Description

Wood pulp composite non-woven fabric

Technical Field

The utility model relates to the technical field of non-woven fabrics, in particular to a wood pulp composite non-woven fabric.

Background

At present, as medical consumables such as disposable bedsheets, polypropylene spun-bonded non-woven fabrics or spun-laced non-woven fabrics are generally adopted for film coating manufacture. The disposable bed sheet prepared by adopting the polypropylene spun-bonded non-woven fabric laminated film is poor in water absorption of polypropylene fibers, so that the comfort and the water absorption of the disposable bed sheet are not ideal. The primary bed sheet prepared by the spunlaced non-woven fabric laminated film is usually the spunlaced non-woven fabric prepared by viscose fiber, has good liquid absorption, the spunlaced non-woven fabric gathers more moisture, the surface of the water-needled non-woven fabric is also relatively moist, and poor use experience is caused to a user.

In the Chinese patent of utility model with publication number CN 211334986U, an antibacterial spunlaced laminated super-absorbent composite non-woven fabric is mentioned, which comprises a rapid water-absorbent non-woven fabric layer, an antibacterial fiber layer, a super-absorbent fiber layer, a spunlaced non-woven fabric layer and a laminated layer which are sequentially arranged. The fiber used by the quick water-absorbing non-woven fabric layer is PE/PP sheath-core composite fiber, and the quick water-absorbing non-woven fabric layer can lead the liquid on the surface of the composite non-woven fabric to be quickly led to the fiber layer adjacent to the quick water-absorbing non-woven fabric layer, so that the surface of the composite non-woven fabric is kept dry.

However, the PE/PP sheath-core composite fiber is used, and when the PE/PP sheath-core composite fiber is used, the sheath layers are mutually bonded and fixed to form the non-woven fabric, and the softness of the rapid water absorption non-woven fabric layer on the surface layer is poor due to the existence of bonding points.

The labels in the figures are illustrated below: 1-a skin-friendly layer; 2-hydrophilic spunbond nonwoven layer; 3-wood pulp spunlaced nonwoven fabric layer; 4-super absorbent fiber layer; 5-an antimicrobial fiber layer; 6-a waterproof breathable film; 7-terylene spunlaced non-woven fabric layer.

Detailed Description

The utility model will be further described with reference to the drawings and specific examples.

Example 1

This embodiment will be described in detail with reference to fig. 1. The wood pulp composite non-woven fabric comprises a skin-friendly layer 1, a hydrophilic spun-bonded non-woven fabric layer 2, a wood pulp spun-bonded non-woven fabric layer 3, a super absorbent fiber layer 4, an antibacterial fiber layer 5 and a waterproof breathable film 6.

The skin-friendly layer 1 is a polylactic acid spunlaced non-woven fabric, and the cross section of the polylactic acid fiber is Y-shaped, cross-shaped or I-shaped. In this example, the polylactic acid fiber is selected to have a Y-shape, a length of 38mm and a fineness of 1.5D. Grooves are formed on the surface of the Y-shaped polylactic acid fiber, so that the Y-shaped polylactic acid fiber has a good flow guiding effect. The liquid on the surface of the device can be quickly guided, so that the liquid can not be gathered at one place, and the absorption of the liquid is quickened.

The hydrophilic spun-bonded non-woven fabric used for the hydrophilic spun-bonded non-woven fabric layer 2 can rapidly guide the liquid in the polylactic acid non-woven fabric to the wood pulp spun-laced non-woven fabric layer 3 adjacent to the liquid.

Further, water permeable holes are formed in the hydrophilic spun-bonded non-woven fabric layer 2, so that liquid can be quickly guided to the wood pulp spun-bonded non-woven fabric layer 3.

The super absorbent fiber layer 4 is super absorbent fiber dust-free paper or super absorbent fiber non-woven fabric. The super absorbent fiber is a novel fiber with large liquid absorption capacity and high liquid absorption speed. Can absorb water, urine, body fluid, blood, etc. The liquid absorption is different from the physical absorption of common fibers, but the liquid is absorbed by a chemical absorption principle, and then the liquid is self-expanded, so that the liquid is stored in the fibers and is difficult to squeeze out. Therefore, the liquid retention capacity is strong. In this example, a superabsorbent fiber nonwoven was selected. Super absorbent fiber dust-free paper or super absorbent fiber non-woven fabrics are purchased from Nantong Jiangchao textile technology Co., ltd.

Further, the antibacterial fiber layer 5 is formed by weaving bamboo charcoal fibers and silver ion yarns. Specifically, the bamboo charcoal fiber yarn and the silver ion yarn are interwoven as warp yarns and weft yarns. The strength of the wood pulp composite non-woven fabric can be increased, and damage to the composite non-woven fabric due to modes such as pedal and the like in the using process is avoided.

Further, the waterproof and breathable film 6 is a TPU, PU, TPFE microporous film. The TPU microporous membrane is selected in the embodiment, has an average pore diameter of 1-10 microns, and has the waterproof and breathable effects.

Example two

This embodiment will be described in detail with reference to fig. 2. The wood pulp composite nonwoven fabric according to the present embodiment differs from the first embodiment in that: one side of the waterproof breathable film 6 far away from the antibacterial fiber layer 5 is compounded with a terylene spunlaced non-woven fabric layer 7. The terylene spunlaced non-woven fabric layer 7 is arranged to protect the waterproof breathable film 6 from being damaged by the outside in the using process.

The foregoing describes in detail preferred embodiments of the present utility model. It should be understood that numerous modifications and variations can be made in accordance with the concepts of the utility model by one of ordinary skill in the art without undue burden. Therefore, all technical solutions which can be obtained by logic analysis, reasoning or limited experiments based on the prior art by the person skilled in the art according to the inventive concept shall be within the scope of protection defined by the claims.
