Abstract

The invention relates to a method for improving crease resistance and shrinkage resistance of a Lyocell bamboo fiber. The method comprises the steps that Lyocell bamboo fiber fabric is subjected to two immersion and two rolling in a finishing liquid, and a drying treatment technology, a baking treatment technology and an aftertreatment technology are adopted sequentially, wherein the finishing liquid comprises the following components in parts by weight: 40-60 parts of finishing agent, 2-3 parts of penetrating agent, and 940-960 parts of water. Compared with the prior art, the method adopts a rapid finishing method, and is low in cost, high in baking speed and ultra-low in methanal release; no catalyst is required; and the crease resistance and the shrinkage resistance of the Lyocell bamboo fiber can be improved greatly. In addition, when a softening agent is added during finishing, the draping (smooth in hand feeling) and the air permeability of the fabric can be improved, and the softening agent has no significant influence on the strength of the fabric.

Description

technical field [0001] The invention relates to the application field of printing and dyeing finishing technology in textile materials, in particular to a method for improving the anti-wrinkle and anti-shrinkage performance of Lyocell bamboo fiber. Background technique [0002] Bamboo pulp fiber has a series of good properties and has been loved by consumers. But the bamboo pulp fiber that uses more at present all is the viscose fiber that replaces cotton pulp with bamboo pulp substantially. Because the viscose bamboo pulp fiber adopts the traditional viscose production process, while maintaining the excellent performance of viscose fiber, it also has the same disadvantages as ordinary viscose fiber, such as insufficient wet strength, hard water, easy deformation of the fabric, and environmental impact Larger etc. Shanghai Leo Fiber Enterprise Development Co., Ltd. has successfully developed Lyocell bamboo pulp fiber with bamboo pulp as raw material by using solvent spinni...
