Embodiment 1

[0023] In this example, 25.0wt% of polyester fiber, 25wt% of hollow polyester fiber and 50wt% of wood pulp fiber are used to prepare by the following spunlace method;

[0024] (1) Raw material preparation: adopt weighing machine to weigh above-mentioned proportioning raw material;

[0025] (2) Preliminary opening and mixing of raw materials: put the raw materials into the cotton blending window opener for preliminary opening and mixing;

[0026] (3) Mixing: use a cotton mixer to further evenly mix the raw materials after the initial opening;

[0027] (4) Fine opening: Use a cotton opener to finely open the evenly mixed raw materials;

[0028] (5) Feeding adjustment: feed the finely opened and loosened raw materials to the carding machine through the finishing cotton box and the air pressure cotton box;

[0029] (1) Carding into a web: the carding machine combs the finely opened raw materials into a fiber web. The range of technological parameters of the carding machine: main...

Embodiment 2

[0039] The preparation method of this example is the same as that of Example 1, except that the raw material hollow polyester fiber is 50wt% and wood pulp fiber is 50wt%. The performance parameter test report of the product under this ratio is as follows:

[0040]

[0041] In the present invention, the wood pulp fiber has good hygroscopicity, and when spunlace, the wood pulp fiber absorbs water and expands, so that the area facing the water becomes larger, the efficiency of the water needle driving the fiber movement is improved, and the fiber entanglement effect is good;

[0042] Polyester fiber has high modulus, good elasticity and ductility, and good wear resistance, so the three-layer composite material has good wear resistance, and the three-layer structure reduces the loss rate of wood pulp fibers;

[0043] In addition, the invention innovatively adopts hollow polyester fiber, which has many curls, increased thickness, and good water absorption, so that the wood pulp ...

Abstract

The invention relates to the technical field of wood pulp wet tissue manufacturing and concretely relates to a different-shape polyester fiber and wood pulp cellulose compound spunlacing wet tissue cloth and a preparation method for the same. The different-shape polyester fiber and wood pulp cellulose compound spunlacing wet tissue cloth is prepared by 25wt% of polyester fibers, 25wt% of hollow polyester fibers and 50wt% of wood pulp fibers via a spunlacing way, or prepared by 50wt% of hollow polyester fibers and 50wt% of wood pulp fibers via a spunlacing way. Compared with the prior art, a wet papermaking technology and carded web-forming spunlacing technology are integrated to one production line and the products are mainly composite cloth; the product prepared by the method is mainly characterized by great water absorbing property, static resistance, even net formation, binder avoidance, bacteria shielding, softness and ventilation; the wood pulp layer and the polyester fiber layer can be formed online; and the proportion of the hollow polyester fibers, the polyester fibers and the wood pulp fibers can be flexibly adjusted, so the thickness of the product can be flexibly adjusted.

Description

technical field [0001] The invention relates to the technical field of wood pulp wet cloth manufacturing, in particular to a composite spunlace wet cloth made of special-shaped polyester fibers and wood pulp fibers and a preparation method thereof. Background technique [0002] In nonwoven fabric processing technology, the hydroentangling method is to continuously spray the fiber web through high-pressure water flow, and under the action of hydraulic force, the fibers in the fiber web will move, displace, rearrange and entangle with each other, so that the fiber web can be strengthened and obtained. Certain physical and mechanical properties. Spunlace non-woven materials have the characteristics of high strength, soft hand feeling, good drapability, no chemical adhesives and good air permeability, and are widely used in various fields; Spunlace composite technology uses fine high-pressure water flow as a means, through two Or the penetration of two or more materials, so tha...
