Problems solved by technology

The usual method is to add antistatic fibers to wool for blending. Metal antistatic fibers have good conductivity and low resistivity, but the hand feel is poor; carbon black antistatic fibers have a single color, which limits the color of the woolen fabric itself; conductive Polymer fibers have poor stability, and their antistatic properties decline slowly over time

Abstract

The invention discloses an antistatic after-finishing process for woolen fabric. The process includes the steps of: soaking in a first finishing solution, primary squeezing, soaking in a second finishing solution, secondary squeezing, drying, shearing and decating, etc. The woolen fabric produced by the antistatic after-finishing process has good stability, nanoscale metal oxides are uniformly distributed on the cloth and not easy to fall off, and the woolen fabric has excellent antistatic and antibacterial functions. By employing citric acid to perform antibacterial finishing on wool fabric, the antibacterial activity of a wool textile is greatly improved, the creasy recovery angle of the wool textile is enhanced, and also the crease resistance of the wool textile is improved.

Description

technical field [0001] The invention relates to textiles and textile technology, in particular to an antistatic post-finishing technology for woolen fabrics. Background technique [0002] With the improvement of people's living standards and the enhancement of environmental protection and health awareness, the requirements for woolen fabrics are getting higher and higher. The fabrics are required not only to have certain softness and wrinkle resistance, but also to have antistatic and antibacterial functions. The usual method is to add antistatic fibers to wool for blending. Metal antistatic fibers have good conductivity and low resistivity, but the hand feel is poor; carbon black antistatic fibers have a single color, which limits the color of the woolen fabric itself; conductive Polymer fibers have poor stability, and their antistatic properties decline slowly with time. Therefore, it is necessary to improve the antistatic wool fabric production process in the prior art. ...
