Abstract
The invention provides a water-absorbing cotton core layer of a paper diaper, and relates to a paper diaper, in particular to the water-absorbing cotton core layer of the paper diaper. The water-absorbing cotton core layer of the paper diaper is characterized in that a water-absorbing layer (4) is formed by a wood-pulp macromolecule water-absorbent resin mixed layer (41), a macromolecule water-absorbing resin layer (42) and fluffy non-woven fabric (43) in a sequentially distributed mode, the upper face and the lower face of the water-absorbing layer (4) are wrapped by middle-layer non-woven fabric (3) and bottom-layer non-woven fabric (5) respectively, the lower portion of the bottom-layer non-woven fabric (5) is provided with a waterproof film (6) and skin-friendly non-woven fabric (7), the upper portion of the middle-layer non-woven fabric (3) is provided with a flow guide layer (2), and the upper portion of the flow guide layer (2) is provided with surface non-woven fabric (1). The water-absorbing cotton core layer eliminates the situation that an existing water-absorbing core layer is prone to being broken in production, and a core is prone to being broken after absorbing water, and is softer and more comfortable.
Description
Technical field
The present invention relates to a kind of diaper, relate 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, coated with dust-free paper up and down, its weak point the first, and water suction is the easy tomography of core body afterwards, causes the phenomenon of leakage of urine; The second, during production, dust-free paper easily ruptures, difficult and realize machine high-speed production.
Summary of the invention
The problem that when the present invention overcomes the rear easy tomography of core body of prior art water suction, production, dust-free paper easily ruptures and more soft, comfortable.
For achieving the above object, the present invention 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 pro-skin non-woven fabrics 7, described lock water layer 4 is arranged in order and is formed by wood pulp hydroscopic high-molecular resin mixed layer 41, hydroscopic high-molecular resin layer 42 and fluffy non-woven fabrics 43, 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 pro-skin non-woven fabrics 7; Described middle level non-woven fabrics 3 tops 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 of the present invention is:
First: due to upper and lower surface employing middle level non-woven fabrics and the bottom non-woven fabrics parcel of lock water layer, non-woven fabrics, is environment-friendly materials of new generation, there is 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. softness: form (2-3D) by fine fibre and dub the molding of shape hot melting cohesion.Finished product pliability is moderate, tool comfort.3. drying, ventilative: polypropylene chip does not absorb water, moisture content zero, 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 FDA food grade materials and produce, containing other chemical compositions, stable performance, nontoxic, free from extraneous odour, not chafe.5. antibacterial, anti-chemical agent: polypropylene belongs to inactivity material, does not damage by worms, and can isolate the erosion that has liquid Endophytic bacteria and insects; Antibacterial, caustic corrosion, finished product be not because erosion affects intensity.6. antibiotic property.Goods tool pulls out aqueous, not mouldy, and can isolate the erosion that has liquid Endophytic bacteria and insects, not mould moth.Pliability, by polypropylene spinning, be directly paved into net hot adhesion and form, tension intensity is non-directional, vertical transverse strength is close, not easy fracture.
Second: because 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 heavy sensation of the body hundreds of the high absorbent function to several thousand times of water, and water retention property is good, once imbibition, become hydrogel, even if pressurization is also difficult to water to separate.The polyelectrolyte that hydroscopic high-molecular resin contains hydrophilic group and cross-linked structure.Before water suction, macromolecular chain is drawn close tangle up mutually, is cross-linked to each other and reticulates structure, thereby reach on the whole fastening.While contacting with water, hydrone is penetrated in resin by capillarity and diffusion, and the ionizing group on chain ionizes in water.Because making macromolecular chain, the electrostatic repulsion between homo-ion on chain stretches swelling.Due to electric neutrality requirement, counter ion can not move to resin outside, the poor formation reverse osmotic pressure of ion concentration between the solution of resin inside and outside.Water further enters in resin under the effect of reverse osmotic pressure, forms hydrogel.Meanwhile, the cross-linked structure of resin itself and hydrogen bond action, limited again the unlimited expansion of gel.Wood pulp is the paper pulp of being made by chip steaming extracting fiber, not containing antibacterial, is different from reclaimed waste paper slurry,
Accompanying drawing explanation
Fig. 1 is decomposing schematic representation of the present invention;
Fig. 2 is that the present invention combines schematic diagram.
Fig. 3 is the structure intention that the present invention locks water layer cross section.
Symbol description in figure: 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, pro-skin non-woven fabrics 7, wood pulp hydroscopic high-molecular resin mixed layer 41, hydroscopic high-molecular resin layer 42, fluffy non-woven fabrics 43.
The specific embodiment
Below in conjunction with concrete enforcement, the present invention is specifically described.
Consult Fig. 1-3, according to preferred embodiment provided by the invention, a kind of lock water cotton core layer of diaper comprises 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 pro-skin non-woven fabrics 7, described lock water layer 4 is arranged in order and is formed by wood pulp+hydroscopic high-molecular resin mixed layer 41, hydroscopic high-molecular resin layer 42 and fluffy non-woven fabrics 43, 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 pro-skin non-woven fabrics 7; Described middle level non-woven fabrics 3 tops are provided with guide layer 2, and guide layer 2 tops are provided with top layer non-woven fabrics 1, and every layer fastens with glue and combines.
