Concavo-convex non-woven fabric and its application in diapers and diapers

A technology of non-woven fabrics and diapers, which is applied in the direction of textiles and papermaking, textile material processing, non-woven fabrics, etc., which can solve the problems of high tide feeling and easy to produce red buttocks, and achieve enhanced water absorption and infiltration speed, absorption and the effect of fast infiltration

Problems solved by technology

The pure cotton non-woven fabric after degreasing processing is very hydrophilic, and its water absorption rate can reach more than 20 times its own weight. Although the diapers using this pure cotton non-woven fabric as the surface layer absorb quickly, they are water-retaining and water-locking. Good, but there is a problem of high tide, and babies are especially prone to red buttocks after using it

Embodiment 1

[0025] Such as figure 1 The concave-convex non-woven fabric shown is made of cotton fiber after degreasing treatment, the length of the cotton fiber is 26-29mm, and the diameter is 1.3-1.6D. The non-woven fabric is provided with a plurality of convex points 1 protruding upwards. The convex points 1 are water-repellent. Between the adjacent convex points 1 is an inner concave surface 2. The inner concave surface 2 is hydrophilic. The hole 3, the connecting surface 4 between the edge of the convex point and the edge of the inner concave surface gradually reduces water repellency from top to bottom, which not only ensures the comfort of use, but also improves the speed of infiltration, and the resulting surface layer has a good use effect.

[0026] Concavo-convex non-woven fabrics are produced in the following steps:

[0027] (1) Cotton fiber after degreasing treatment in advance, the length of cotton fiber is 26-29mm, and the diameter is 1.3-1.6D;

[0028] (2) Since the cotton...

Embodiment 2

[0036] The application of concave-convex non-woven fabrics in diapers, concave-convex non-woven fabrics are used as the surface layer of diapers. The paper diaper comprises an outer cover and a core therein, and the outer cover includes a bottom layer and the concave-convex nonwoven fabric described in Example 1.

Abstract

The invention relates to the field of non-woven fabric materials, in particular to a concave-convex type non-woven fabric. Cotton fiber after ungrease treatment is taken as a raw material, a pluralityof protruding points which protrude upwards are arranged on a non-woven fabric, concave surfaces are formed between adjacent protruding points, the protruding points are hydrophobic, and the concavesurfaces are hydrophilic. The concave-convex type non-woven fabric has the advantages that the non-woven fabric is soft, pure white, dry and comfortable and rapid in absorption and infiltration speed,and the natural cotton fiber is used.

Description

technical field [0001] The invention relates to the field of nonwoven materials, in particular to a concave-convex nonwoven used as the surface layer of diapers. Background technique [0002] Many surface layers of paper diapers adopt 3D embossing structure, such as the Chinese patent whose publication number is CN203677388U, the title is a diaper with a 3D three-dimensional embossed surface layer, and a plurality of 3D three-dimensional embossed patterns are distributed on the surface layer. Due to the addition of 3D three-dimensional embossing, the surface of the diaper is more beautiful and the contact area between the baby's buttocks and the diaper is reduced, thereby enhancing the breathability and making the baby healthier and more comfortable during the use of the diaper. [0003] At present, there are two main materials for the surface layer of diapers on the market, one is synthetic fibers, such as hot-melt bonded non-woven fabrics and spunbond non-woven fabrics, an...
