Abstract
Description
Technical Field
The present invention relates to a two-layer structure woven fabric having a first layer and a second layer and a garment using the same.
Background
Conventionally, woven fabrics used for sportswear and underwear include woven fabrics made of natural fibers typified by cotton, woven fabrics made of synthetic fibers such as polyester and polyamide, and woven fabrics and mixed fabrics of natural fibers and synthetic fibers.
In general, sportswear and underwear are worn in contact with the skin, and are often worn with sweating, and therefore, the following requirements are required: the fabric continuously absorbs sweat generated by sweat for a long time, and the sweat is rapidly moved, diffused to the outer surface of the fabric and dispersed in the outside air, so that the fabric is good in quick-drying property.
However, although a knitted fabric made of natural fibers such as cotton and wool absorbs sweat well, the absorbed sweat is held and hardly scattered, and therefore, continuous water absorption and quick drying properties are poor, and wearing comfort may be impaired due to an increase in weight caused by holding sweat, a cold feeling, and the like.
In addition, a woven or knitted fabric made of synthetic fibers of polyester, nylon or the like has excellent washing and wearing properties, but on the other hand, absorbed sweat is difficult to move and diffuse, and therefore there are the following problems: a sticky and stuffy feel due to wetting by sweat is produced.
As a fabric made of synthetic fibers to which water mobility and water diffusibility are imparted,patent document 1 proposes a water-absorbing fabric in which one surface of the fabric is made of ultrafine fibers of 0.7 denier or less and the other surface of the fabric is made of fibers of 1 denier or more and having a fineness of four times or more of the ultrafine fibers. In the examples ofpatent document 1, there are described: a woven fabric, a nonwoven fabric, a knitted fabric, or the like, in which one surface is composed of ultrafine fibers of 0.05 denier, 0.07 denier, 0.1 denier, or the like, and the other surface is composed of a thread having a very large single yarn fineness 33 to 44 times as large as the ultrafine fibers.
Patent document 2 proposes a knitted fabric in which the surface is composed of hydrophilic fiber yarns such as kapok and the back surface is composed of the hydrophilic fiber yarns and hydrophobic synthetic fiber yarns.
Patent document 3 proposes a water-permeable woven or knitted fabric comprising a plurality of non-hygroscopic fiber strands having different single yarn fineness, one surface of the woven or knitted fabric comprising strands having a single yarn fineness in the range of 1.0 to 2.5 deniers, and the other surface comprising strands having a single yarn fineness 1.5 times or more larger than the single yarn fineness.

Problems to be solved by the invention
When the fabric of the two-layer structure is used for sports wear or underwear, the inner layer on the skin side can rapidly absorb sweat on the skin and transfer it to the outer layer, and the layer on the skin side itself does not retain sweat as much as possible, which is important for reducing the sticky feeling, the stuffy feeling, the moist feeling, and the cold feeling, and not sustaining the above feeling for a long time. On the other hand, once the outer layer retains sweat transferred from the inner layer, it simultaneously quickly diffuses the sweat to the surface and evaporates, which is important for quickly restoring the feeling of wear.
However, the fabric ofpatent document 1 is intended to obtain water absorption and water retention, and although the initial water absorption is good, the ultrafine fiber group retains water after water absorption, and is significantly inferior in continuous water absorption and quick-drying properties, and is not suitable for sportswear and underwear ideally having the above-described properties.
The woven fabric of patent document 2 is said to have relatively good initial water absorbency since it contains hydrophilic fiber threads on the back surface, but is inferior in water permeability, continuous water absorbency, quick-drying property, and the like from the back surface to the front surface.
The water-permeable woven fabric of patent document 3 has a sweat-releasing function, quick-drying property, washing property and wearing property, but may not be sufficiently coped with when sweat is much.
The present invention has been made in view of the above problems, and an object of the present invention is to: provided are a two-layer structure woven fabric suitable for use in clothing worn in contact with the skin, such as sportswear and underwear, and clothing using the same.
Means for solving the problems
The double-layer structure woven fabric of the present invention for solving the above problems is characterized in that:
is a two-layer structure woven fabric with a first layer and a second layer,
the first layer is woven by a first strand with the section void ratio of 30-250%,
the second layer is woven by second strands with the section void ratio of 150-450%,
the second strand has a cross-sectional porosity that is 1.3 to 7.0 times the cross-sectional porosity of the first strand.
According to the two-layer structure woven fabric having the above-described configuration, by having the first layer woven with the first strands having the cross-sectional porosity of 30% to 250% and the second layer woven with the second strands having the cross-sectional porosity of 150% to 450%, the cross-sectional porosity of the second strands is 1.3 times to 7.0 times the cross-sectional porosity of the first strands, it is achieved that moisture is absorbed in the second layer, and at the same time, moisture is rapidly transferred from the second layer to the first layer having a smaller cross-sectional porosity, and is diffused and volatilized. Therefore, the absorption amount is less likely to be saturated, and excellent continuous water absorption and drying rate can be obtained. As a result, in the clothing using the woven fabric having the two-layer structure having such a configuration, the second layer quickly absorbs sweat on the skin and transfers the sweat to the first layer, and the first layer spreads the transferred sweat on the surface, so that the sweat can be dried in a short time. In addition, even in the case of a large amount of perspiration, the perspiration is not easily retained in the second layer, and therefore, the feeling of coolness is small and the wearing feeling can be quickly recovered.
In the woven fabric of the two-layer structure of the present invention,
the first strand preferably comprises hydrophilic fibers.
According to the two-layer structure woven fabric configured as described above, by the first strands containing the hydrophilic fibers, it is possible to quickly suck moisture absorbed in the second layer to the first layer. Therefore, the clothes using the double-layer structure knitted fabric having the above structure can obtain good dry feeling.
In the woven fabric of the two-layer structure of the present invention,
the second strand preferably comprises hydrophobic fibers.
According to the two-layer structure woven fabric configured as described above, by the second strands including the hydrophobic fibers, the moisture absorbed in the second layer can be more quickly sucked to the first layer. Therefore, the clothes using the double-layer knitted fabric having the above-described structure can further improve the dry feeling.
In the double-layered structure woven fabric according to the present invention,
preferably 20g/m per unit area2 ～150g/m2 The first strand of yarn.
The woven or knitted fabric having a two-layer structure comprising 20g/m per unit area2 ～150g/m2 The first strand of (2) can uniformly diffuse appropriately absorbed water without excessively increasing the water retentivity of the two-layer structure woven fabric.
The garment according to the present invention for solving the above problems is characterized in that:
the knitted fabric is composed of the two-layer structure knitted fabric of any one of the above in such a manner that the second layer is the skin side.
According to the garment configured as described above, since the second layer is on the skin side by using the double-structure knitted fabric having the first layer and the second layer of the present invention, sweat on the skin is rapidly sucked by the second layer and transferred to the first layer, and the transferred sweat is diffused to the surface by the first layer, so that the second layer can be dried in a short time. In addition, even in the case of a large amount of perspiration, the perspiration is not easily retained in the second layer, and therefore the feeling of coolness is small, and the wearing feeling can be quickly recovered.

Detailed Description
Hereinafter, the woven fabric and garment having a two-layer structure of the present invention will be described. However, the present invention is not intended to be limited to the following configurations.
< two-layer Structure woven Fabric >
The two-layer structure woven fabric of the present invention has a first layer woven from a first strand and a second layer woven from a second strand. The knitting structure of the double-layer knitted fabric of the present invention is not particularly limited as long as it is a knitted fabric structure having a double-layer structure. For example, there may be mentioned: circular knitted fabrics such as roman weave, milano weave, tuck weave, back deer-point weave, single concavo-convex weave, compound concavo-convex weave and double-sided fabric, single warp knitted fabrics such as half-bed knitting, back half-bed knitting, warp knitting chain weave and warp inclined flat weave, and double warp knitted fabrics such as double raschel and double-sided warp knitted fabric. By the two-layer structure woven fabric of these woven structures, excellent drying properties can be obtained.
In terms of the finished density, the knitting density of the double-layer structure knitted fabric of the present invention is preferably in the range of 30 courses to 100 courses/2.54 cm, and 20 wales to 80 wales/2.54 cm. When the knitting density is within the above range, a knitted fabric excellent in drying property, water absorption property, texture and the like can be obtained.
The weight per unit area of the woven or knitted fabric having a two-layer structure of the present invention is preferably 50g/m2 ～270g/m2 . If the weight per unit area is less than 50g/m2 Woven fabric of double layer structureMay be of poor strength. If the weight per unit area is more than 270g/m2 The texture of the double-layer structure woven fabric may be impaired.
In the case of the strands which are an aggregate of the single yarns, the intervals between the single yarns constituting the strands have the same structure as the capillaries and absorb water, and therefore, the smaller the intervals between the single yarns constituting the strands and the smaller the cross-sectional porosity of the strands, the stronger the water absorption effect of the strands. In the two-layer structure woven fabric of the present invention, by using, as the first strands woven into the first layer, strands having a smaller cross-sectional porosity than the second strands woven into the second layer, it is possible to diffuse moisture such as sweat absorbed by the second layer disposed on the skin surface side into the first layer and volatilize the moisture.
The apparent cross-sectional area of the entire strand was SY (m2 ) The total fineness of the strands is represented by FY (dtex) the specific gravity of the fiber material constituting the strand is set to gF When (1) below, the cross-sectional void fraction of the strand is defined by:
cross-sectional void ratio (%) = { (S)Y ×10000×gF )-FY }/FY ×100 (1)。
In the present invention, a material obtained by embedding a two-layer structure woven fabric with a resin is cut in the warp direction or weft direction, the cut cross section is photographed with a scanning electron microscope, the photographed image is subjected to image processing, and the apparent cross section S of the whole strand measured at 5 positions of the processed image is usedY (m2 ) The average value of (2) is calculated from the above equation (1).
For the first strand, a strand having a cross-sectional void ratio of 30% to 250% is used. When the cross-sectional porosity of the first strand is 30% to 250%, the mobility of water in the first layer is improved, and the diffusivity of water in the two-layer structure woven fabric is improved. In addition, the texture of the double-layer structure woven fabric becomes soft. If the cross-sectional void ratio of the first strands is less than 30%, the density of the strands themselves becomes high, and therefore the texture of the braid may become hard, or the intervals between the strands become large, whereby the needle hole may become large and the weave of the fabric may become transparent. If the cross-sectional porosity of the first strand is more than 250%, the mobility of moisture from the second layer to the first layer on the skin surface side becomes poor, the moisture diffusibility in the two-layer structure woven fabric decreases, and thereby the quick-drying property may decrease.
For the second strand, a strand having a cross-sectional void ratio of 150% to 450% is used. When the cross-sectional porosity of the second strand is 150% to 450%, moisture of sweat or the like on the skin can be rapidly absorbed by the second layer. In addition, the water retentivity in the second layer can be prevented from being excessively high. When the cross-sectional porosity of the second strands is less than 150%, the difference in cross-sectional porosity between the first strands and the second strands becomes small, and therefore, the difference in liquid elevation due to capillary phenomenon becomes small, and moisture is not easily transferred from the second layer to the first layer, and the moisture diffusibility may be reduced, and the quick-drying property may be reduced. In addition, the feeling upon contact with the skin may be impaired. If the cross-sectional void ratio of the second strand is more than 450%, physical properties such as pilling resistance and hooking resistance of the double layer structure woven fabric may be reduced.
In the woven fabric having a two-layer structure of the present invention, the cross-sectional porosity of the second strand is in the range of 1.3 to 7.0 times the cross-sectional porosity of the first strand. By satisfying the above range, the capillary phenomenon effectively acts, and moisture rapidly moves and diffuses from the second layer to the first layer. Therefore, the two-layer structure woven fabric of the present invention suppresses retention of moisture in each layer, and even in the case of a large amount of perspiration, the absorption amount of perspiration does not easily reach saturation, and the continuous water absorption property is excellent, and the drying speed is improved. This can prevent the double-layer woven fabric from becoming heavy due to sweat and from becoming sticky to the skin.
As the form of the first strand, a drawn yarn, a crimp-processed yarn, a spun yarn, or the like can be used. For example, the latent crimp of false twist textured yarns, side-by-side yarns, and the like is preferably used. The total fineness of the first strand is preferably 30dtex to 167dtex. When the first strand is a filament, the single yarn fineness of the first strand is preferably 0.06dtex to 2.3dtex, more preferably 0.3dtex to 1.5dtex. When the first yarn is a spun yarn, the single yarn fineness of the first yarn is preferably 50 to 120. When the total fineness and the single yarn fineness of the first strand are within the above-described ranges, the strength and softness of the two-layer structure woven fabric become good. If the total fineness and the single yarn fineness of the first strand are outside the above ranges, the strength of the double-layer structure woven fabric may be insufficient, or the double-layer structure woven fabric may become heavy.
The fiber material of the first yarn is not particularly limited, and examples thereof include natural fibers such as cotton, wool, and silk, regenerated fibers such as rayon and acetate, and synthetic fibers such as polyester, polyamide, polyacrylonitrile, and polypropylene. In the two-layer structure woven fabric of the present invention, the higher the hydrophilicity of the first layer, the more rapidly the moisture absorbed in the second layer diffuses into the first layer, and therefore the water absorption property as a two-layer structure woven fabric is also improved. Therefore, the first strand preferably comprises hydrophilic fibers. By the first strands comprising hydrophilic fibres, moisture absorbed by the second layer can be quickly absorbed into the first layer knitted from the first strands. In the present invention, the hydrophilic fiber is intended to be a fiber having good wettability with water, and examples thereof include a fiber obtained by hydrophilically processing a natural fiber such as cotton or silk, a semi-synthetic fiber such as rayon, a synthetic fiber, and the like, which have been subjected to refining treatment. The woven or knitted fabric made of these hydrophilic fibers alone is preferably a woven or knitted fabric having a performance of 2 seconds or less when measured by the dropping method according to JIS L1907 water absorption test method. Various combinations of the above hydrophilic fibers may be used for the first strand. The hydrophilic processing of the synthetic fiber is not particularly limited as long as it satisfies the above water absorption performance, and conventionally known methods such as sweat absorption processing in a bath can be mentioned. Further, as the first strand, a strand composed only of hydrophilic fibers may be used, but a composite strand such as a blended yarn of hydrophilic fibers and fibers having a performance exceeding 2 seconds in the dropping method described above, a twisted yarn, an interwoven mixed yarn, and a core yarn may also be used. However, the water absorption performance is preferably 2 seconds or less, more preferably 1 second or less, in the above-mentioned dropping method.
Preferably, the woven fabric having a two-layer structure contains 20g/m per unit area2 ～150g/m2 More preferably 30g/m2 ～120g/m2 Of the first strand of (a). If the woven fabric of the two-layer structure contains 20g/m per unit area2 ～150g/m2 The first strand of (2) can uniformly diffuse the water properly absorbed without excessively increasing the water retentivity of the two-layer structure woven fabric. If the first strand per unit area of the double layer structure woven fabric is less than 20g/m2 Since the moisture is not uniformly diffused, the drying speed may be reduced, if it is more than 150g/m2 The drying speed may be slowed down due to too high water retention. Further, when the first yarns include the hydrophilic fiber, the first yarns preferably account for 20% to 80% by weight of the double-layer structure woven fabric. The first strands containing the hydrophilic fibers account for 20 to 80% of the weight of the two-layer structure woven fabric, and thus moisture such as sweat absorbed by the second layer can be rapidly diffused and volatilized over a wide range.
As the form of the second strand, a drawn yarn, a crimped yarn, a spun yarn, or the like can be used. For example, it is preferable to use a false twist yarn, a side-by-side yarn, or the like, a latent curl line, but in the two-layer structure woven fabric of the present invention, it is more preferable that the second strand is a strand having a form different from that of the first strand. The total fineness of the second strand is preferably 30dtex to 222dtex. Preferably, a filament is used for the second strand, the single yarn fineness of which is preferably 1dtex to 6dtex, more preferably 1.5dtex to 3dtex. If the total fineness and the single yarn fineness of the second strand are within the above ranges, the skin touch of the second layer knitted from the second strand is not impaired. In addition, the moisture can be effectively moved and diffused to the first layer composed of the first strands by the surface tension without impairing the stiffness, texture, and the like of the two-layer structure woven fabric, and the texture of the two-layer structure woven fabric can be favorably maintained. If the total fineness and the single yarn fineness of the second strand are outside the above ranges, the touch of the second layer may be impaired, and the stiffness, texture, and the like of the double layer structure woven fabric may be impaired.
The fiber material of the second yarn is not particularly limited, and examples thereof include natural fibers such as cotton, wool, and silk, regenerated fibers such as rayon and acetate, and synthetic fibers such as polyester, polyamide, polyacrylonitrile, and polypropylene. Wherein the second strand preferably comprises hydrophobic fibers. In the garment using the woven or knitted fabric having a two-layer structure of the present invention, the second yarn contains the hydrophobic fiber, and therefore, the second layer disposed on the skin surface side can provide a good dry feeling. The hydrophobic fiber means a fiber having poor wettability with respect to moisture, and a raw synthetic fiber may be preferably used. Examples of such fibers include polyesters such as polyethylene terephthalate, polybutylene terephthalate, polyoxyethoxybenzoate, polyethylene naphthalate, and cyclohexanedimethylene terephthalate, polyester-based fibers composed of a copolyester obtained by copolymerizing these polyesters with a 3 rd diol component such as isophthalic acid, a sulfoisophthalic acid component, propylene glycol, butylene glycol, cyclohexanedimethanol, and diethylene glycol, polyamide-based fibers such as nylon 6, nylon 66, and aromatic nylons, polyolefin-based fibers such as polyethylene and polypropylene, acrylic fibers, and biodegradable synthetic fibers composed of an aliphatic polyester compound such as polycaprolactone, polybutylene succinate, and polylactic acid. When the knitted fabric comprising these hydrophobic fibers alone is measured by the dropping method according to the above-mentioned "JIS L1907 water absorption test method", it preferably has a performance of 5 seconds or more. As the fibers having such water absorbing property, fibers obtained by subjecting semisynthetic fibers such as rayon and cotton, which are exemplified as the fibers exhibiting hydrophilicity, to hydrophobic processing can be used. Examples of the hydrophobic processing include hydrophobic processing by treatment with a general hydrophobic processing agent containing fluorine, silicon, olefin, or the like, and there is no particular limitation as long as the above water absorption performance is satisfied.
Preferably, the woven fabric having a two-layer structure contains 30g/m per unit area2 ～180g/m2 Of the second strand of yarn. If the second strand is included in the above range, moisture such as sweat can be rapidly absorbed in the second layer. If the second strand per unit area of the double-layer structure woven fabric is less than 30g/m2 The absorption speed of moisture in the second layer is slowed, which may cause the two-layer structure woven fabric to become thick if it is more than 180g/m2 Then the two-layer structure is wovenThe object may become heavy.
< clothing >
The woven fabric having a two-layer structure of the present invention can be suitably used as materials for various clothes. In this case, in view of sweat absorption, it is preferable to use a double-structure knit fabric to constitute the garment as follows: a second layer using a second strand having a large cross-sectional porosity of the strand is disposed on the skin side (back side), and a first layer using a first strand having a small cross-sectional porosity of the strand is disposed on the outer side (front side). If this configuration is made, even if the wearer of the garment of the invention sweats, the second layer can rapidly absorb the sweat on the skin and transfer it to the first layer, which can diffuse the transferred sweat to the surface, drying in a short time. In addition, even when a large amount of sweat is produced, sweat is not easily retained in the second layer, so that the feeling of coolness is small and the feeling of wear can be quickly recovered.
< characteristics of woven/knitted Fabric having two-layer Structure >
[ Water absorption time ]
As for the garment using the two-layer structure knitted fabric of the present invention, if the second layer is used so as to be disposed on the skin surface side as described above, the garment having the higher water absorption rate of the second layer and the more excellent dry feeling can be obtained. Therefore, in the two-layer structure woven or knitted fabric of the present invention, the water absorption time measured by the dropping method according to JIS L1097 is preferably 10 seconds or less as an index of the water absorption rate of the second layer. The measurement of the water absorption time was carried out by the following procedure. First, five 20cm × 20cm test pieces were taken from the two-layer structure woven fabric, and each piece was mounted on a metal ring having a diameter of about 15cm without applying an additional tension. Next, the height from the surface of the second layer of the test piece to the tip of the burette was adjusted to 10mm, and about 0.04ml of distilled water of 20 ℃ ± 2 ℃ was dropped through the burette. Then, the time until the water droplets dropped on the test piece were absorbed by the test piece (until the test piece absorbed the water droplets, the specular reflection disappeared, and only the test piece remained wet) was measured, and the average value was calculated for five test pieces. If the water absorption time is 10 seconds or less, it is evaluated that the garment using the two-layer structure woven fabric can rapidly absorb moisture such as sweat. When the water absorption time exceeded 10 seconds, the garment using the two-layer structure woven fabric was evaluated as sticky.
[ Water absorption diffusion area ]
In order for moisture to be continuously absorbed into the second layer, it is desirable that moisture rapidly diffuse in the first layer. Therefore, in the woven or knitted fabric having a two-layer structure of the present invention, as an index of moisture diffusion in the first layer, a water absorption diffusion area is preferably 23cm2 The above. The water absorption diffusion area was measured by the following procedure. First, 0.1ml of a 2.5% dye aqueous solution (Kayacion Red P-4BN Liquid 25, manufactured by Nippon chemical Co., ltd.) was dropped on the surface of the second layer, and after 120 minutes from the dropping, the longitudinal width and the lateral width of a trace of the dye spreading by wetting on the surface of the first layer were measured, and the water absorption spread area was calculated from the product of the longitudinal width and the lateral width. When the water absorption diffusion area is 23cm2 In the above case, it is evaluated that the moisture absorbed in the second layer is rapidly diffused and the drying property is good. When the water absorption diffusion area is less than 23cm2 In this case, the moisture diffusion property was insufficient, and the absorption of moisture in the second layer was not continued.
[ drying time ]
In order to continuously absorb moisture such as sweat in a garment using a two-layer structure woven fabric, it is desirable that the two-layer structure woven fabric has a water-absorbing quick-drying property. Therefore, the two-layer structure woven or knitted fabric of the present invention is preferably dried for 23 minutes or less as an index of the water absorption quick-drying property. The drying time was determined by the following procedure. First, a test piece of 10cm × 10cm, whose weight was measured in advance by wetting for 2 hours or more at a temperature of 20 ℃ and 65% RH, was allowed to stand on a metal ring having a diameter of 9cm, and then 0.1ml of distilled water was dropped on the surface of the second layer by a syringe to allow the test piece to absorb water, thereby measuring the weight of the test piece. Thereafter, the weight was measured every 1 minute, and the time taken until the residual water content was less than 10% was set as the drying time. If the drying time is 23 minutes or less, the absorbed moisture can be rapidly dried, and thus the garment using such a two-layer structure woven fabric is evaluated to be able to continuously absorb sweat. If the drying time exceeds 23 minutes or less, the water absorption quick-drying property becomes insufficient, and the garment using the two-layer structure woven fabric is evaluated as failing to continuously absorb sweat.
< other embodiment >
The garment using the double-structure knitted fabric of the present invention is mainly intended to improve the water absorption and quick-drying properties of sweat during perspiration of a person, but if the moisture retention is more important than the water absorption and quick-drying properties of sweat, the garment may be configured using a double-structure knitted fabric in which the front and back surfaces are reversed (i.e., a double-structure knitted fabric in which the first layer is placed on the skin side and the second layer is placed on the front surface side). In this case, the garment with the front and back reversed properly wets the surface of the skin by the first layer of the double-structure braid, and thus it is possible to prevent the skin from being excessively dried, for example, in sunny days in winter.

For comparison, woven fabrics having a two-layer structure outside the scope of the present invention were produced (comparative examples 1 and 2), and the same measurements and evaluations were performed.

The finished density of the first layer and the second layer is 55 courses and 33 wales. In the woven fabric having a two-layer structure of example 1, the woven fabric contained 61g/m per unit area2 The proportion of the first strand to the weight of the double-layer structure woven fabric was 46.9%. The weight per unit area of the double-layer structure woven fabric was 130g/m2 。
< example 2>

The following table 1 shows specific information, measurement results and evaluation results of the two-layer structure woven fabrics of examples 1 to 5 and comparative examples 1 and 2.
[ Table 1]
It was confirmed that the water absorption and diffusion area of any of the two-layer structure woven fabrics of examples 1 to 5 was 23cm2 Both the above and drying times were 23 minutes or less, and all had excellent continuous water absorbability. In addition, theThe following trends were found: the larger the porosity ratio of the two-layer structure woven fabric of examples 1 to 5, the larger the water absorption diffusion area and the shorter the drying time. Thus, it is believed that: the excellent continuous water absorbability of the two-layer structure woven fabrics of examples 1 to 5 was obtained by: the porosity ratio is in the range of 1.3 to 7.0, and thus the moisture absorbed by the second layer rapidly moves and diffuses into the first layer.
On the other hand, in the woven fabrics having a two-layer structure of comparative examples 1 and 2 having a porosity of 1.0, neither of the water absorption diffusion areas was sufficient to be 23cm2 And the drying time is more than 23 minutes, and the continuous water absorbability is poor.
Industrial applicability of the invention
The woven fabric having a two-layer structure of the present invention can be used for clothing worn in contact with the skin, such as sportswear and underwear.
