Abstract

The invention discloses a preparation method of fiber and flax blended yarn. The weight content of the flax fiber is 45-75%, and the rest is elastic polyester fiber. The preparation includes: pretreatment, cleaning, carding, drawing and roving , degumming, bleaching, pickling, washing and spinning. The production method provided by the invention can prepare the elastic polyester fiber and flax fiber blended yarn with hygroscopicity, lightness, glossiness, air permeability, antibacterial property and anti-mite property. The blended yarn of elastic polyester fiber and flax fiber of the present invention has high spinnability and good elasticity, and the cloth woven with it is soft, comfortable, breathable, sweat-absorbing, antibacterial and elastic, and has a novel and fashionable appearance. The invention blends elastic polyester and flax fiber, which can make up for the low elasticity of the hemp fiber, and makes the fabric feel comfortable and elastic, and can improve the style and feel of the blended yarn.

Description

technical field [0001] The invention relates to the textile field, in particular to a preparation method of fiber and flax blended yarn. Background technique [0002] The main components of hemp are cellulose, lignin, hemicellulose, pectin and so on. The biggest difference between hemp products and other natural cellulose textiles is that degumming is required. The degumming process has a great impact on the quality of hemp, and it is also one of the research topics that the hemp industry has devoted itself to in recent years. The traditional degumming process is mainly based on chemical degumming, that is, the chemical reagents that can dissolve pectin are used to boil the hemp fiber for a long time to remove the gum. The treatment of large volumes of degumming wastewater puts 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 flax and dry hemp. There are 5 degumming production enterprise...
