Embodiment 1

[0053] A kind of preparation method of non-woven fabric, comprises the following steps:

[0054] (1) material preparation: uniformly mixing cupro fibers and bamboo fibers to obtain mixed fibers, wherein the mass fraction of the cupro fibers accounting for the mixed fibers is 85%;

[0055] (2) carding: the mixed fibers are subjected to a carding process to obtain carded mixed fibers;

[0056] (3) Combing: the combed mixed fiber is subjected to a combing process to obtain the combed mixed fiber;

[0057] (4) Cross-lapping: the combed mixed fibers are subjected to a cross-lapping process to obtain a mixed fiber web;

[0058] (5) Spunlace: the mixed fiber web is processed by a spunlace process to obtain a nonwoven fabric after spunlace treatment;

[0059] (6) Drying: drying the non-woven fabric after the spunlace treatment to obtain a dried non-woven fabric;

[0060] (7) Winding: the finished non-woven fabric is wound up.

Embodiment 2

[0062] A kind of preparation method of non-woven fabric, comprises the following steps:

Abstract

The invention discloses a non-woven fabric and a preparation method thereof. The preparation method comprises the following steps of (1) preparing materials, namely, uniformly mixing copper ammonia fibers, polylactic acid fibers and bamboo fibers to obtain mixed fibers; (2) oiling treatment, namely, spraying an oil preparation on the mixed fibers to obtain oiled mixed fibers; (3) performing common combing; (4) combing; (5) performing cross lapping, namely, carrying out cross lapping process treatment on the combed mixed fibers to obtain a mixed fiber web; (6) performing spunlace; (7) performing drying; (8) performing deoiling treatment, namely, performing deoiling treatment on the dried non-woven fabric by using a deoiling agent, and then performing water washing and drying to obtain the de-oiled non-woven fabric; and (9) winding, namely, winding the finished product of the de-oiled non-woven fabric. The prepared non-woven fabric is soft, breathable and antibacterial, and has good water absorption performance and mechanical properties.

Description

technical field [0001] The invention belongs to the technical field of textiles, and in particular relates to a nonwoven fabric and a preparation method thereof. Background technique [0002] Non-woven fabric has the characteristics of soft, breathable, cotton-like, and recyclable. It is a kind of direct use of polymer slices, short fibers, and filaments to pass the fibers through airflow and mechanically into a net, and then through spunlace, acupuncture, heat, etc. Non-woven fabric formed by rolling and strengthening. The main raw material of non-woven fabrics is polypropylene, in addition to polyester, nylon, polypropylene, viscose fiber, chitin fiber, microfiber, tencel, silk, bamboo fiber, wood pulp fiber, seaweed fiber, etc. [0003] The production process of non-woven fabrics is simple and the price is cheap. It is widely used in sanitary absorbent materials, medicine, transportation, and textile materials for shoemaking. Among them, medical and health applications i...
