Abstract

The invention discloses a preparation method of polylactic acid fiber/polyester fiber blended fabric with moisture absorbing and perspiration functions. The method comprises the steps that acrylic acid monomers are taken as modified monomers, and modified acrylic acid fiber is obtained by adopting an in-situ aggregation method; a layer of nano silica is condensed on the surface of the modified acrylic acid fiber; finally the fabric is obtained by covering the modified polylactic acid fiber with the polyester fiber and blended. The fabric prepared by means of the method has good moisture absorbing and permeability and is soft, comfortable, simple to prepare and low in cost.

Description

Technical field: [0001] The invention relates to the field of textile preparation, in particular to a method for preparing a moisture-absorbing and perspiration-absorbing polylactic acid fiber / polyester blended fabric. Background technique: [0002] With the acceleration of human civilization, the advancement of science and technology and the change of people's consumption concept, people have higher and higher requirements for clothing, food, housing, transportation and other aspects that affect the quality of human life. As far as clothing is concerned, people's requirements for clothing have shifted from the initial practicality of covering the body, warmth, and protection to functionality, efficacy, and comfort. Among them, especially higher requirements are put forward for the comfort aspect of clothing fabrics. Recently, a survey of consumers in the United States shows that 81% of consumers regard the comfort of clothing as their main choice, and the style and design ...
