[Previous technology] In the yarn knitting process of using the sea-island type composite fiber to prepare yarn knitting fabrics, because of the high knitting speed, high-quality yarns are required, especially the smoothness of the yarns. In addition, a large number of complicated steps are required after the manufacturing of the yarn knitting product. For example, reducing the weight of the mouth | fluffing, technical color, etc. 'Therefore, it is necessary to properly control the thermodynamic properties and viscoelastic properties of the yarn. … ^ In particular, the thermodynamic properties and viscoelastic properties of the sea-island composite, the various sea components of the sea-island and the island structure are very important for the preparation of yarn knitted fabrics. I-bismuth bismuth sea-island composite fiber is made of π ... factory and made of polymer that can form fibers as island components, and can be made by combining two components with two weaving. Formed into a sea-island type fiber, its manufacture is mainly to prepare ultra-fine Daniel fiber. In other words, the sea-island type composite fiber is made, and the sea-island type composite fiber is treated with an alkali liquid to dissolve the sea component of the alkaline soluble polymer, so that ultra-fine Daniel fiber containing only the island component is prepared. " In this way, the method for preparing the ultra-fine Daniel fiber from the sea-island type composite fiber is more advantageous for obtaining the textile and drawing of the ultra-fine Daniel fiber than the method for preparing the ultra-fine Daniel fiber by the direct spinning method. Excellent processability, however, the former requires 2 spinning & knitting or the final process after weaving to dissolve and remove the sea hydrate by a process using an organic solution. 2.

其王要係使用驗性可溶聚酯共聚物。其理由係可利用鹼性溶液溶解該 海成份’及其減少重量之設備已廣泛使用於一般聚酯纖維之重量減少 製程中，因而不需特殊設備，且該有機溶液之回收成本不高。 若該島成份為尼龍，由於當溶解該海成份時該尼龍被該鹼性溶液 渗透之程度極低’故該海成份之溶解速度較不具重要性。然而，若該 島成份為聚酿’則在該海成份完全溶解前該島成份將被滲透，其係因 居水Ss對之A解性較弱，而使該海成份之溶解速度較低，以致於溶 解後紗線之物理性質大幅的降低變差。結果，該起毛性質變得較差， 及難以使最終產物具有所需之外觀及觸感。 另一方面，若該海成份之溶解速度快，則可避免上述問題發生， 並且1液始、度、4解溫度及時間皆可減少，因而能減少溶解所需成本 及增加產率。 為了增加該海成份之溶解速度，則需增加一共聚化合物之含量。 然而，若戎共聚化合物之含量增加過多，則該海成份在改善溶解性同 時，亦將變成一非定形聚合物，其將不具固定熔點而僅具有一軟 丨softening point〕，因而造成紡織困難。 t 用於製備/母島型衩合纖維之習用驗性可溶聚醋之製備技術係包含 下列方法：〔1〕一種方法，其係將二甲基—5—磺基苯二甲酸鈉 | dimethy卜5-sulfoisophthalate sodium，DMIS〕或低分子量之聚 ’蹄二醇〔polyalkyleneglycol，PAG〕以一聚酯聚合反應製程使其共 聚化·’〔 2〕一種方法，其係混合聚酯與高分子量之pAG ;及〔3〕— 種方法，其係混合聚酯聚合物與高分子量之pAG。 在藉由紡織、拉絲及假撚以製備海島型複合纖維的過程中，利用 上述^用技術之fe性可/谷I g旨做為該海成份及利用該聚g旨做為該島成 份，該紗線之平坦性質將降低及其編織性質將變差。藉由減少該紗線 及編織機之缝針間之摩擦力，該紗線之平坦性質將可用以改善可製備 性。 Θ績次頁（發明說明頁不敷使用時，請註記並使用續頁)The king is to use an experimentally soluble polyester copolymer. The reason is that an alkaline solution can be used to dissolve the sea component ’and its weight reduction equipment has been widely used in the general polyester fiber weight reduction process, so no special equipment is needed, and the recovery cost of the organic solution is not high. If the island component is nylon, the dissolution rate of the sea component is less important because the nylon is extremely low in penetration by the alkaline solution when the sea component is dissolved. However, if the island component is poly-fermented, the island component will be infiltrated before the sea component is completely dissolved, which is due to the weak A-solubility of the resident water Ss, and the dissolution rate of the sea component is low. So that the physical properties of the yarn after the dissolution are greatly reduced. As a result, the fluffing properties become poor, and it is difficult to give the final product the desired appearance and feel. On the other hand, if the dissolving speed of the sea component is fast, the above problems can be avoided, and the starting temperature, degree, and temperature and time of one solution can be reduced, so the cost required for dissolution can be reduced and the yield can be increased. In order to increase the dissolution rate of the sea component, it is necessary to increase the content of a copolymer compound. However, if the content of the Rong copolymer compound is increased too much, the sea component will also become an amorphous polymer while improving the solubility, which will not have a fixed melting point but only a softening point, thus causing textile difficulties. t The preparation technique of customary soluble polyacetate used for the preparation / mother island-type fiber is composed of the following methods: [1] A method which uses dimethyl-5-sodium sulfophthalate | dimethy 5 -sulfoisophthalate sodium, DMIS] or low-molecular weight poly'ene glycol [polyalkyleneglycol, PAG] is copolymerized by a polyester polymerization process · '[2] a method, which is a mixture of polyester and high molecular weight pAG; And [3] a method in which a polyester polymer and a high molecular weight pAG are mixed. In the process of preparing sea-island composite fibers by weaving, drawing, and false twisting, the fe characteristics of the above-mentioned application technology can be used as the sea component and the polyg can be used as the island component. The flatness of the yarn will decrease and its weaving properties will deteriorate. By reducing the friction between the yarn and the needles of the knitting machine, the flatness of the yarn can be used to improve manufacturability.

According to the present invention, the melting viscosity of the sea component and the island component can be appropriately adjusted to improve the hair-cutting property and the sea-island shape property. Normally, during the textile process, an extruder is used to apply pressure to a spinner so that the fiber holder can change everything. The extruder has a lower flow rate and shear rate, and the mud of the spinner is lower. The rate and shear rate are high. The shear stress of the shear rate is called melting viscosity (MV), which varies with polymer properties. However, 'about the sea-island type composite fiber prepared by combining two or more polymers with textiles', because the melting viscosities of the sea ingredients are different from each other, the shear stress is also different, and the result affects the The formation of the sea and island components of the composite fiber and the physical properties of the composite fiber. Therefore, in order to obtain the physical properties required for the uniform formation of the sea-island type cross-section for supply, it is necessary to select a polymer having sea and island components with appropriate melting viscosity. In particular, as for the products of knitted fabrics with raised yarns, in order to exhibit the raising properties, appearance, and feel of extremely fine yarns, the polymers used in this sea-island composite fiber maintain relatively viscous properties, rather than maintaining melt viscosity. Sex. l · ^ The melting viscosity of the island component polymer and the seawater component polymer of the present invention are cut at a rate of _G [l / s]. The difference [△ _] is the island component polymer. The difference between the melt viscosity and the melt viscosity of the sea-component polymer at a shear rate of 500 [l / s] is 20% to 70%. That is, the delta solution at the spinner position-the delta Mv value at the extruder position. ^ In other words, the melting viscosity difference between the island component polymer and the sea component polymer due to the increase in shear rate should be reduced [ΑΜν]. Otherwise, it is difficult to achieve a sufficient amount of drawing and tangling of the raised fibers in the yarn = knitted fabric, which may reduce the directional properties of the island component and its knitting properties. Please refer to the graph shown in Fig. 5 of the present invention, which reveals the Δ grab and h conditions when all variability increases. As shown in Figure 5, it confirms that the melting viscosity between the island component and the sea component is poor Θ’Ι′Μ rhyme (please note and use 顚 when the page is not enough to use) »3/03/12 9 200415271

The graph in Figure 4 reveals the correlation between the melt viscosity and shear rate of each component. When the melt viscosity [MVs] of the right child component is greater than the melt viscosity [MV:] of the island component polymer, the cross section of the island-type fiber will be difficult to form. It will cause the island composition to decrease in miles or form uneven sea composition, so the fluffing properties during the fluffing process will be poor, and it will be difficult to show the appearance and feel of the final product. Furthermore, the difference in melting viscosity [ΔΜν] between the sea component and the island component is preferably less than 1,000 poise. If the melting viscosity difference [ΔΜν] of the sea component and the island component is greater than 1,000 poises, the island component will stick to each other during the textile process, and the island component may produce unprecipitated fibers, which are dissolved It still cannot be precipitated after processing. Based on the above-mentioned reasons, there may be a risk that the fiber fluffing state becomes uneven when the yarn is knitted, and the outer appearance is changed, the writing effect is deteriorated, and the touch is coarse. The melting viscosity of the island component polymer can be adjusted by the original viscosity. The melting viscosity of the sea component polymer can be adjusted by appropriately adjusting the type of copolymer and the copolymer. Quantitative and copolymerization reaction conditions are adjusted. / For example, when adjusting the melt viscosity of the sea component polymer, 3 to 15 mol% of DIMS is a poly (p-phenylene) copolymer, and the average molecular weight is greater than & 4 to 20% by weight of polyethylene. Alcohol [polyethyleneglyc〇1]. Compared with preparing a large number of sea-island composite fibers by the method of weaving, drawing, and false twisting, the present invention can prepare materials with flat properties, so it is more suitable for high-speed yarn weaving. ^ In addition, by appropriately adjusting the thermodynamic and viscoelastic properties of the sea and island components of the yarn, the appearance and feel of the yarn knitted fabric of the present invention can also be improved. Furthermore, the thermodynamic properties and viscoelastic properties of the sea and island components of the yarns in the first and second aspects of the present invention can be adjusted in the preparation process, so that The thermodynamic and viscoelastic properties of the island components are adjusted to a predetermined range.

Therefore, the maximum temperature value in a temperature combination in which a polymer crystal can be melted is regarded as the melting point of a crystalline region. The melting point of the same polymer varies depending on the crystal size. The larger the crystal, the higher the melting point. When the melting point of a polymer can be divided into two or more, the main value of the melting point is the peak value at a low temperature of a car parent, and the secondary value is the symptom value at a higher temperature. The reason that the melting point of a polymer is separated into two is because the polymer's crystal size distribution is separated into two by external factors. If the temperature of the peak of the primary melting point is higher than the temperature of the peak of the secondary melting point, it means that there are more crystals of large size than crystals of small size. However, if the temperature of the peak of the primary melting point is lower than the temperature of the peak of the secondary melting point, it means that there are more small-sized crystals than large-sized crystals. In addition, the total heat of fusion | AHi] of the island component crystals is about 2 to 5 times greater than the total heat of fusion [ahs] of the sea component crystals with respect to the textile drawn yarn [y] of the present invention. Furthermore, the total heat of fusion [AHy] of the textile drawing yarn [y] crystal is about 1 to 1.5 times greater than the total heat of fusion [^ Ηχ] of the spinning & drawing yarn "X] crystal. The total heat of fusion [eight] of the textile drawing yarn [y] is equal to + ahs. The heat of crystallization refers to the heat per unit weight required to melt the large and small crystals in a polymer. The heat of dissolution becomes larger as its crystallinity becomes larger. At the same time, relative to the textile drawing yarn [y] of the present invention, a first transition peak temperature [Ta] is in a graph of a viscoelastic index [tan account]. 120 to 150 ° C, and a second transition temperature [T <] is -50 to -20 ° C. In addition, the first transition peak [a-peak] < viscoelastic index [tan δ a] is 0. 10 spirit 0. 20, and the second transition peak [Lu-Peak "viscoelastic index [tan5 phantom 0. 03 to 0. 08.

Regarding the sea-island composite fiber of the present invention having the above-mentioned thermodynamic properties and viscoelastic properties, since it has excellent fuzzing properties, it can improve the appearance and feel of the yarn knitted fabric. As described above, the sea-island type composite fiber of the present invention has the melt viscosity of the sea and island components mutually matched. Therefore, in the process of dissolving sea ingredients and fluffing, the formability, the fluffing property, and the tactile feeling of the cross-section of the fiber become better, and the probability of worsening the physical properties of the yarn is reduced to a small size. As a result, the sea-island composite fiber of the present invention is particularly suitable as a yarn for producing a yarn-knitting fabric. The measurement of changes in the physical properties of yarns and yarn-knitted fabrics is as described in Ding. Crystal melting point [° C] / heat of fusion [Joules / gram] Crystal melting point [° c] and heat of fusion [Joules / gram] are measured by differential scanning calorimetry 丨 differential scanning calorimetry (DSC).
