Embodiment 1

[0036] refer to Figure 1a , figure 2 , a method for preparing a three-dimensional embossed cotton layer non-woven fabric, comprising the steps of:

[0037]a. Prepare ES fiber and comb it into a web. This step is realized through two production links:

[0038] As a well-known ES fiber production process, it includes: polyethylene / polypropylene melt spinning - oiling - winding - bundling - drafting - oiling - crimping - drying - shearing - -Package.

[0039] The preparation link of the ES fiber of the present embodiment comprises the following steps:

[0040] a1, according to the known ES fiber preparation steps, polyethylene and polypropylene are melt-spun to obtain ES fiber filaments;

[0041] a2, carry out oiling treatment to the fiber filament tow of step 1 by oiling roller, oiling agent is the mixture of polyether silicone oil and isomeric alcohol ether, the weight ratio of polyether silicone oil and isomeric alcohol ether is 5: 1. The oiling rate is controlled at 0.2...

Embodiment 2

[0055] Embodiment 2: In view of the fact that the three-dimensional embossed cotton-containing layer non-woven fabric is applied on the surface material of diapers or sanitary napkins, Embodiment 2 provides a more friendly skin-friendly three-dimensional embossed cotton-containing layer non-woven fabric. The preparation method differs from Example 1 in that:

[0056] refer to Figure 1b , in the step b, the cotton fiber layer 1' is composed of a plurality of cotton fiber units tiled on the upper surface of the ES fiber layer 2' in a grid arrangement, and the laying area of ​​the cotton fiber layer 1' occupies an area of ​​ES 65% of the area of ​​the fiber layer 2 ', this web forming process will greatly sacrifice the speed of the non-woven fabric production line, under the same process conditions, its power consumption will increase more than 20% relative to Example 1, but the obtained The skin-friendly touch of the three-dimensional embossed non-woven fabric is significantly...

Abstract

The invention relates to a three-dimensional embossed cotton-layer-containing non-woven fabric and a preparation method thereof, and mainly solves the problem of skin touch and reverse osmosis of theexisting cotton-layer-containing non-woven fabric. The non-woven fabric prepared by the preparation method comprises a laminated ES fiber layer and a cotton fiber layer fixedly arranged above the ES fiber layer through hot air or spunlace, wherein the cotton fiber layer contains 0.05% to 0. 10% of a water-repellent oil agent; the laying area of the cotton fiber layer accounts for 30%-70% of the area of the ES fiber layer; the square gram weight of the cotton fiber layer is 10-25 g / cm2, and the line density of the cotton fibers is 1.8-2.2dtex; the square gram weight of the ES fiber layer is 15-25 g / m2, and the line density of the ES fiber layer is 2.0-2.3dtex; the cotton fiber layer and the ES fiber layer below the cotton fiber layer are provided with embossing, wherein the embossed area accounts for 15-30% of the area of the cotton fiber layer; and the ES fiber contains a mixture of polyether silicone oil, isomeric alcohol ether and citric acid. The prepared non-woven fabric is mainlyused as a surface layer material of disposable absorbent articles.

Description

technical field [0001] The invention relates to a nonwoven fabric and a manufacturing method thereof, in particular to a three-dimensional embossed cotton-containing layer nonwoven fabric which can be used for the surface layer of absorbent products and a preparation method thereof. Background technique [0002] At present, non-woven fabrics are widely used in the surface layer of sanitary absorbent products such as sanitary napkins, sanitary pads and diapers. Mainly air-through non-woven fabrics, hot-rolled non-woven fabrics and spun-bonded non-woven fabrics. When non-woven fabrics are used as the surface layer of absorbent products, they need to be in close contact with the human body, so non-woven fabrics must be soft, breathable and skin-friendly. Although the current air-through non-woven fabrics, hot-rolled non-woven fabrics and spunbond non-woven fabrics are soft to the touch, compared with spunlace non-woven fabrics, spunlace non-woven fabrics are softer and skin-fr...
