Abstract

The utility model discloses a novel pass through liquidity fiber non -woven fabric, by constituteing in upper fibre (1), mean fiber (2) and lower floor's fibre (3), connect gradually about upper strata fibre (1), mean fiber (2) and lower floor's fibre (3) and be in the same place, the constitution be the surface course and the water conservancy diversion layer of panty -shape diapers, sanitary towel, saved the colloid between traditional surface course and the water conservancy diversion layer, whole design grammes per square metre is 40~50gsm. The utility model discloses the non -woven fabrics takes 3 kinds of different fibres to comb the web formation separately, guarantees when liquid pierces through this product, pierces through upper strata, middle level fast and spreads at the quick multiple spot of lower floor for the panty -shape diapers of this production, sanitary towel surface course are superior to ordinary non -woven fabrics on infiltration speed, dry and comfortable degree, and have improved the soft handle degree of disposable urine trousers, sanitary towel, and have better fluffiness, be fit for the knurling processing of surface course, make the product more have market competition.

Description

A kind of novel liquid-permeable nonwoven fibrous fabric

Technical field

This utility model belongs to diaper, sanitary towel field, particularly liquid-permeable nonwoven fibrous fabric, more specifically relates to the liquid-permeable nonwoven fibrous fabric of the top flat use being suitable as the disposable liquid absorbing article such as disposable diaper or sanitary towel.

Technical background

At present, well-known liquid-permeable nonwoven fibrous fabric is by single fiber or two kinds of fibers by single combing or two combing carding, and the fibrous layer of non-woven fabrics is made up of 2 layers of non-woven fabrics at most; Present disposable sanitary napkin, diaper are formed by surface layer and guide layer, because surface layer and guide layer laminating need glue (not hydrophilic), ooze (permeability) under having influence on product, make sanitary towel, the dry and comfortable degree of diaper, soft degree all unsatisfactory, need to be improved.

Summary of the invention

Goal of the invention: design a kind of novel liquid-permeable nonwoven fibrous fabric, improves the water absorbing properties of sanitary towel, diaper surface layer, strengthens sanitary towel, the dry and comfortable degree of diaper, soft degree.

Technical scheme: a kind of novel liquid-permeable nonwoven fibrous fabric, be made up of top fiber 1, mean fiber 2 and lowermost fibre 3, described top fiber 1, mean fiber 2 and lowermost fibre 3 be with 3 carding machines to different fibers respectively combing form, pass through hot blast net-forming process again by the PE melting layer of fibrous outer, be connected in turn up and down after being cooled to net.

Described top fiber 1 is the ET fiber of Superfine Thermoplastic's synthetic resin, PET sandwich layer/PE cortex or integument, and this layer directly contacts human skin, and short fiber improves product sense of touch; And this layer of fiber surface is coated with low diffusion, high hydrophilic hydrophilic oil preparation, make human body fluid control minimum at the diffusingsurface of this layer, human body fluid is ooze under vertical single-point;

Described mean fiber 2 is the short fiber of high fluffy thermoplastic synthetic resin, and belong to high crimped fibre, elastic effect is good, and form loft and the good supporting layer of dry and comfortable degree, human body fluid oozes under this layer presents bending single-point;

Described lowermost fibre 3 is the EP fiber of Superfine Thermoplastic's synthetic resin, PP sandwich layer/PE cortex or integument, and hydrophilic oil preparation that is hydrophilic at its surface smear height, high diffusivity, after making human body fluid penetrate described top fiber 1, mean fiber 2, the diffusion of large area multiple spot is carried out by described lowermost fibre 3, human body fluid evenly, is rapidly absorbed by the core body of disposable urine trousers, sanitary towel, is diffused into every one side of core body.

The surface layer of just diaper, the sanitary towel of described top fiber 1, mean fiber 2 and lowermost fibre 3 composition and guide layer, eliminate the colloid between traditional surface layer and guide layer, whole design grammes per square metre is 40 ~ 50gsm; The core body of diaper, sanitary towel refers to their water-absorbing body.

Beneficial effect: this utility model non-woven fabrics takes 3 kinds of different fibers to carry out respective carding, ensure when liquid penetrates this product, quick penetration upper strata, middle level in lower floor's quick multiple spot diffusion, make the diaper of this production, sanitary towel's surface layer be better than common non-woven fabric on lower infiltration rate degree, dry and comfortable degree, and improve the soft degree of disposable urine trousers, sanitary towel; And there is good bulkiness, be applicable to the embossing processing of surface layer, make product have more the market competitiveness.

Accompanying drawing explanation

Detailed description of the invention

This utility model is described further below in conjunction with embodiment and accompanying drawing thereof:

A kind of novel liquid-permeable nonwoven fibrous fabric, be made up of top fiber 1, mean fiber 2 and lowermost fibre 3, described top fiber 1, mean fiber 2 and lowermost fibre 3 be with 3 carding machines to different fibers respectively combing form, pass through hot blast net-forming process again by the PE melting layer of fibrous outer, be connected in turn up and down after being cooled to net.

Described top fiber 1 is the ET fiber of Superfine Thermoplastic's synthetic resin, PET sandwich layer/PE cortex or integument, and this layer directly contacts human skin, and short fiber improves product sense of touch; And this layer of fiber uses low diffusion, high hydrophilic hydrophilic oil preparation, make human body fluid control minimum at the diffusingsurface of this layer, human body fluid is ooze under vertical single-point; Described mean fiber 2 is the short fiber of high fluffy thermoplastic synthetic resin, and belong to high crimped fibre, elastic effect is good, and form loft and the good supporting layer of dry and comfortable degree, human body fluid oozes under this layer presents bending single-point; Described lowermost fibre 3 is the EP fiber of Superfine Thermoplastic's synthetic resin, PP sandwich layer/PE cortex or integument, and employing height is hydrophilic, the hydrophilic oil preparation of high diffusivity, after making human body fluid penetrate described top fiber 1, mean fiber 2, the diffusion of large area multiple spot is carried out by described lowermost fibre 3, human body fluid evenly, is rapidly absorbed by the core body of disposable urine trousers, sanitary towel, is diffused into every one side of core body.

The foregoing is only preferred embodiments of the present utility model, not in order to limit this utility model, any amendment done within spirit of the present utility model and principle, equivalent replacement, improvement etc., all should be included within system structure of the present utility model.
