Application of atmospheric pressure low temperature plasma in cotton fabric desizing

Abstract

In order to solve the problem of high energy consumption and high pollution in traditional alkali desizing process of cotton fabric, atmospheric pressure low temperature plasma was used to treat pure cotton fabric containing sizing. Through single factor variable experiment, the optimum desizing process was determined. The optimum process conditions were as follows: the optimum treatment power of plasma is 400 W, the optimum treatment time is 15 min, the distance between discharge electrode and grey cloth is 1 mm, the optimum alkali boiling concentration is 8 g/L. Compared to traditional desizing process, the usage of caustic soda was saved by 60%.

Utilization of factory tea (Camellia sinensis) wastes in eco-friendly dyeing of jute packaging fabrics

“…There are four main types of desizing methods: oxidative, alkali, enzyme, and acid. In most cases, alkaline desizing was used [ 19 ]. To achieve the best desizing effect, a high desizing temperature is recommended.…”

A sustainable desizing process for PVA-sized cotton fabric using ultraviolet C

“…Because of its high viscosity, PVA is not removed completely from fabric in the conventional desizing process. 22,23 The water usage in desizing is 33.5% of the total water consumed in pretreatment. Degradation of PVA during desizing can facilitate easy removal from the fabric.…”
