SUMMERY OF THE UTILITY MODEL

Therefore, aiming at the content, the utility model provides a paper diaper with a reinforced structure and a composite core body, and solves the problems of low liquid absorption speed and limited liquid absorption capacity of the conventional paper diaper.

In order to achieve the purpose, the utility model is realized by the following technical scheme:

a reinforced structure paper diaper with a composite core body comprises a paper diaper body, wherein the paper diaper is defined to have a longitudinal direction along the length direction and a transverse direction along the width direction, a front waistline and a rear waistline are arranged on the two longitudinal sides of the paper diaper body, hook surface magic tapes are arranged on the two transverse sides of the rear waistline, a hair surface magic tape is arranged on one surface, away from the skin, of the front waistline, the hook surface magic tapes are in adhesion fit with the hair surface magic tapes, a health-care layer is arranged on one surface, close to the skin, of the front waistline, the health-care layer corresponds to the navel position of an infant, the health-care layer is formed by blending magnetic yarn fibers and cotton fibers, leakage-proof guards are arranged on the two transverse sides of the paper diaper body, the paper diaper body comprises a breathable surface layer, a flow guide layer, an absorption layer and a leakage-proof bottom layer which are sequentially stacked from top to bottom, a plurality of bulges are arranged on the breathable surface layer, the middle part of water conservancy diversion layer is equipped with the horizontal guiding gutter of echelonment, the absorbed layer includes compound core, the upper surface of compound core is equipped with elasticity non-woven fabrics, the lower surface of compound core is equipped with down elasticity non-woven fabrics, compound core includes by the first absorbent core body, fluffy non-woven fabrics and the second absorbent core body that from top to bottom set up of stromatolite in proper order.

Further improvement: and C-shaped fixing parts are arranged at two longitudinal sides of the absorption layer.

Further improvement: the air-permeable surface layer is formed by weaving warp and weft, and the warp and the weft all include antibacterial fiber and crisscross cotton fiber and the viscose of winding in the antibacterial fiber outside.

Further improvement: the breathable surface layer is provided with liquid permeating holes, and the liquid permeating holes penetrate through the upper surface and the lower surface of the breathable surface layer.

Further improvement: the positions of the liquid-permeable holes and the bulges do not intersect.

Further improvement: the first water absorption core body and the second water absorption core body are a mixture of fluff pulp and high water absorption resin.

Further improvement: the water absorption multiplying power of the first water absorption core body is smaller than that of the second water absorption core body.

Further improvement: the leak protection bottom layer includes ventilative film and sets up the hydrophobic non-woven fabrics in ventilative film below.

By adopting the technical scheme, the utility model has the beneficial effects that:

the raised arrangement can increase the gap between the skin of the infant and the liquid-permeable surface layer, so that urine discharged by the infant can permeate downwards for sufficient time to be absorbed by the absorption layer, and is not easy to adhere to the skin of the infant, thereby improving the wearing comfort and the air permeability of the paper diaper.

The health-care layer is arranged at the position corresponding to the navel of the infant, the blood microcirculation is promoted by utilizing the characteristic of the magnetic yarn fiber, the health-care function on the navel is good, and the comfort level of the navel position when the paper diaper is worn is improved by utilizing the soft and breathable characteristic of the cotton fiber.

The setting of water conservancy diversion layer can guide the urine from the infiltration nature of liquid permeability surface course infiltration fast, is absorbed by the absorbed layer and pins, keeps the dry and comfortable nature on close skin top layer. Because infant's urine is mostly infiltrated by the middle part of liquid permeability surface course, is equipped with the horizontal guiding gutter of echelonment in the middle part of water conservancy diversion layer, can increase the infiltration space of urine, when a large amount of urine were discharged, the urine was earlier along horizontal guiding gutter infiltration downwards, and the part is absorbed by the absorbed layer middle part, and the part rethread guiding layer longitudinal diffusion that is too late to absorb is finally absorbed by the absorbed layer.

The absorbed layer includes upper and lower two-layer elasticity non-woven fabrics and sets up the composite core body between two-layer elasticity non-woven fabrics, and the setting of composite core body has improved panty-shape diapers's imbibition ability, goes up the structure of absorbed layer is reinforceed in the setting of elasticity non-woven fabrics and lower elasticity non-woven fabrics, and the elasticity of increase absorbed layer avoids forming gel hard to one side after the composite core body absorbs the urine inflation, extrudes infant's skin influence travelling comfort of wearing. Furthermore, the C-shaped fixing parts are arranged on the two longitudinal sides of the absorption layer, so that the connection of each layer of the absorption layer is more stable, and the fault phenomenon is avoided. The composite core body comprises a first water absorption core body, fluffy non-woven fabrics and a second water absorption core body, the fluffy non-woven fabrics can enable urine to be uniformly distributed, and the composite core body is prevented from forming a lump fault. The first water absorption core body and the second water absorption core body adopt different water absorption multiplying powers, have reverse osmosis, and the liquid that seeps down is absorbed and locked by the second water absorption core body when the first water absorption core body can't be.

The breathable surface layer is formed by weaving warps and wefts, wherein the warps and the wefts comprise antibacterial fibers and cotton fibers and viscose fibers which are wound on the outer sides of the antibacterial fibers in a staggered mode. The antibacterial fiber has good antibacterial and bactericidal functions; the viscose fiber has the characteristics of good moisture absorption, softness and air permeability; the cotton fiber has the characteristics of softness, fluffiness, no irritation, good hygroscopicity and the like, and the three fibers are matched with each other, so that the urine of infants can be absorbed and conducted and diffused downwards, the dryness and comfort of the liquid-permeable surface layer are kept, meanwhile, the air permeability and the antibacterial property of the paper diaper are improved, and the peculiar smell emitted by excrement is reduced. The arrangement of the liquid permeable holes further accelerates the infiltration speed of urine.
