Abstract

The invention discloses a preparation method of elastic polyester fiber and flax fiber blended yarns by adopting a bio-enzyme method. The weight content of flax fibers is 45 percent to 75 percent and the balance is elastic polyester fibers; the preparation method comprises: pre-treating, blowing, cotton carding, drawing, roving, degumming, bleaching, acid washing, washing and spinning. By adopting the preparation method provided by the invention, the elastic polyester fiber and flax fiber blended yarns with moisture absorption, lightness and thinness, glossiness, air permeability, antibacterial property and mite inhibition property can be prepared. The elastic polyester fiber and flax fiber blended yarns provided by the invention have high spinnability and good elasticity; cloth woven by the elastic polyester fiber and flax fiber blended yarns is light and soft, comfortable and breathable, has sweat-absorbing and antibacterial properties and has elasticity; the cloth has novel and fashionable appearance. The elastic polyester fibers and the flax fibers are blended and the disadvantage of low elasticity of the flax fibers can be made up; a prepared fabric has a comfortable hand feeling and has good elasticity; the style of the blended yarns can be improved and the hand feeling of the blended yarns can be improved.

Description

technical field [0001] The invention relates to the field of textiles, in particular to an elastic polyester fiber and flax fiber blended yarn. Background technique [0002] The main components of hemp are cellulose, lignin, hemicellulose, pectin, etc. The biggest difference between hemp products and other natural cellulose textiles is that they need to be degummed. The degumming process has a great impact on the quality of hemp, and it is also one of the topics that the hemp industry has been working on in recent years. The traditional degumming process is mainly chemical degumming, that is, using chemical reagents that can dissolve pectin to scour the hemp fiber for a long time to remove the gum. The disposal of large volumes of degumming wastewater places great pressure on the environment and costs. Taking Hubei as an example, Hubei Province has an annual output of more than 4,000 tons of refined and dried flax. There are 5 degumming production enterprises, and only 2 h...
