Desizability and Biodegradability of Textile Warp Sizing Materials and Their Mechanism: A Review.

Desizing and biodegradability are considered among the most important processes in the textile industry. Desizing removes the protective coating on the surface of yarn to ensure high efficiency and enhanced quality of subsequent stages such as bleaching, scouring, dyeing and printing, while good biodegradation ensures green environment. Many different factors including the interaction in the sizing agent, the interaction between the sizing agent and textile fibers, and desizing agent influence the desizing efficiency of sizing agents. During the last decades, sizing with new agents with enhanced properties have been extensively studied. However, reviews on desizability, biodegradability of sizing agents and their mechanism seem very rare. In this review, methods of desizing which are frequently used and the factors that influence desizing mechanism and biodegradability have been discussed. Knowledge about the effect of these factors in desizing and biodegradation, and the mechanisms could serve as a platform to develop sizing agents with good desizing efficiency and biodegradability.
