Abstract

The utility model relates to a paper diaper, in particular to a water retaining cotton core layer of the paper diaper. The water retaining cotton core layer of the paper diaper is characterized in that a water retaining layer (4) is formed by sequential arrangement of a wood pulp macromolecule water-absorbent resin mixed layer (41), a macromolecule water-absorbent resin layer (42) and fluffy non-woven fabric (43). The upper and lower faces of the water retaining layer (4) are wrapped up through middle layer non-woven fabric (3) and bottom layer non-woven fabric (5), a waterproof thin film (6) and skin-friendly non-woven fabric (7) are arranged below the bottom layer non-woven fabric (5), a guide layer (2) is arranged above the middle layer non-woven fabric (3), and surface layer non-woven fabric (1) is arranged above the guide layer (2). The water retaining cotton core layer of the paper diaper overcomes the defects that an existing water retaining core layer is prone to fracture when produced, and layers of a core body are prone to breakage after absorbing water. Moreover, the water retaining cotton core layer of the paper diaper is softer and more comfortable.

Description

A kind of lock water cotton core layer of diaper

Technical field

This utility model relates to a kind of diaper, relates in particular to a kind of lock water cotton core layer of diaper.

Background technology

The lock water sandwich layer of conventional paper urine pants adds hydroscopic high-molecular resin in fluffy non-woven fabrics, coats with dust-free paper up and down, and its weak point the first, suction is the easy tomography of core body afterwards, causes the phenomenon of leakage of urine; The second, dust-free paper ruptures easily during production, and is difficult and realize the machine high-speed production.

The utility model content

The problem that dust-free paper ruptured easily when this utility model overcame the rear easy tomography of core body of prior art suction, production and more soft, comfortable.

For achieving the above object, this utility model is by the following technical solutions:

A kind of lock water cotton core layer of diaper, comprise: top layer non-woven fabrics 1, guide layer 2, middle level non-woven fabrics 3, lock water layer 4, bottom non-woven fabrics 5, waterproofing membrane 6 and close skin non-woven fabrics 7, described lock water layer 4 is arranged in order by wood pulp hydroscopic high-molecular resin mixed layer 41, hydroscopic high-molecular resin layer 42 and fluffy non-woven fabrics 43 and forms, and the upper and lower surface of lock water layer 4 adopts middle level non-woven fabrics 3 and bottom non-woven fabrics 5 parcels; Described bottom non-woven fabrics 5 belows are provided with waterproofing membrane 6 and close skin non-woven fabrics 7; Non-woven fabrics 3 tops, described middle level are provided with guide layer 2, and guide layer 2 tops are provided with top layer non-woven fabrics 1.

Compared with prior art, the lock water cotton core layer beneficial effect of a kind of diaper described in the utility model is:

First: because the upper and lower surface of lock water layer adopts middle level non-woven fabrics and bottom non-woven fabrics parcel, non-woven fabrics is environment-friendly materials of new generation, have following characteristics, 1. light weight: take acrylic resin as main production raw material, proportion only 0.9, only has 3/5ths of Cotton Gossypii, tool bulkiness, good hand touch.2. soft: as to form (2-3D) by fine fibre and dub the molding of shape hot melting cohesion.The finished product pliability is moderate, the tool comfort.3. drying, ventilative: polypropylene chip does not absorb water, moisture content zero, and the finished product water-repellancy is good, and by 100% fibrous tool porous, breathability is good, easily keeps cloth cover dry and comfortable.4. nontoxic, nonirritant: product adopts and meets the FDA food-grade raw materials and produce, and does not contain other chemical constituents, stable performance, nontoxic, free from extraneous odour, not chafe.5. antibiotic, anti-chemical agent: polypropylene belongs to the inactivity material, does not damage by worms, and can isolate the erosion that has antibacterial and insects in the liquid; Antibiotic, caustic corrosion, finished product do not affect intensity because of erosion.6. antibiotic property.The goods tool pulls out aqueous, and is not mouldy, and can isolate the erosion that has the interior antibacterial of liquid and insects, not mould moth.Pliability, directly be paved into the net hot adhesion by polypropylene spinning and form, tension intensity is non-directional, vertical transverse strength is close, not easy fracture.

Second: because the lock water layer is comprised of wood pulp, hydroscopic high-molecular resin and fluffy non-woven fabrics 43, hydroscopic high-molecular resin it have absorptance from the heavy sensation of the body hundreds of the high absorbent function to several thousand times of water, and water retention property is good, when in case imbibition becomes hydrogel, even pressurization also is difficult to moisture from out.Hydroscopic high-molecular resin contains the polyelectrolyte of hydrophilic group and cross-linked structure.Before the suction, macromolecular chain is drawn close tangle up mutually, and being cross-linked to each other reticulates structure, thereby reaches on the whole fastening.When contacting with water, hydrone is penetrated in the resin by capillarity and diffusion, and the ionizing group on the chain ionizes in water.Owing to making macromolecular chain, the electrostatic repulsion between homo-ion on the chain stretches swelling.Because the electric neutrality requirement, counter ion can not be moved to the resin outside, the poor formation reverse osmotic pressure of the ion concentration between the solution of resin inside and outside.Water further enters under the effect of reverse osmotic pressure in the resin, forms hydrogel.Simultaneously, the cross-linked structure of resin itself and hydrogen bond action have limited again the unlimited expansion of gel.Wood pulp is the paper pulp of being made by the chip steaming extracting fiber, does not contain antibacterial, is different from the reclaimed waste paper slurry,
