Preparation method of hot-blast non-woven fabric containing cellulose fiber

Abstract

The invention provides a preparation method of a hot-blast non-woven fabric containing cellulose fiber. By adopting modified bicomponent fiber, the bicomponent fiber and cellulose fiber are subjectedto cotton blending and carding, after hot-blast bonding is adopted, the mixture is fed to a take-up machine to be taken up, and the hot-blast non-woven fabric is obtained; due to the fact that the adopted modified bicomponent fiber and the cellulose fiber are subjected to the hot-blast effect, after the bicomponent fiber skin is molten, the bicomponent fiber and cellulose are subjected to hydrogenbond crosslinking, and therefore the cellulose fiber and the bicomponent fiber are stuck together, and no fiber falling phenomenon is caused. According to the modified bicomponent fiber, strong-polarity groups are introduced into the skin, and the hydrogen bond affinity characteristic is achieved; in the hot-blast machining process, the bicomponent fiber and the cellulose fiber are subjected to hydrogen bond crosslinking, the strong-polarity groups are introduced into the skin, functional master batches containing the strong-polarity groups are added into the bicomponent skin raw materials, and the weight ratio of the master batches is 0.1-20% of the skin. The hot-blast non-woven fabric has the advantage of being skin-friendly, comfortable and the like.

Description

technical field [0001] The invention relates to the field of materials for sanitary products, in particular to a method for preparing a hot-air nonwoven fabric containing cellulose fibers. Background technique [0002] Cellulose fibers, such as cotton and viscose fibers, are increasingly favored by consumers of hygiene products due to their hydrophilic and comfortable characteristics. However, since cellulose fibers do not have thermal bonding properties, only spunlace or Mechanical reinforcement such as acupuncture, the resulting non-woven fabric is relatively compact, with poor bulkiness and fluid conductivity. If the cellulose fiber is directly mixed into the low-melting bicomponent fiber for processing, the cellulose fiber is easy to fall out due to the incompatibility between the hot-melt process and the bicomponent fiber, which will affect the use. Contents of the invention [0003] In order to solve the above problems, the purpose of the present invention is to pro...

[0002] Cellulose fibers, such as cotton and viscose fibers, are increasingly favored by consumers of hygiene products due to their hydrophilic and comfortable characteristics. However, since cellulose fibers do not have thermal bonding properties, only spunlace or Mechanical reinforcement such as acupuncture, the resulting non-woven fabric is relatively compact, with poor bulkiness and fluid conductivity

If the cellulose fiber is directly mixed into the low-melting point bi-component fiber for processing, because the hot-melt process is not compatible with the bi-component fiber, the cellulose fiber is easy to fall out, affecting the use
