Effects of Ozone Treatment on Wool Scales and Mechanical Properties

Abstract

The aim of this study was to investigate the ozone treating effects on wool scales and wool fabrics mechanical property through experiments and observation. For this purpose, detailed investigations on the role of mechanical properties surfacing topography, changes in component and membrane structure were investigated. Then, a micro explanation was given to discuss the mechanism of wool shrinkage. Because scales are the necessary factor for shrinking, this study is of great significance to the work of shrinkproofing.

A review of the sustainable methods in imparting shrink resistance to wool fabrics

“…One of the advantages of O 3 treatment is that it can etch the edge of cuticles like the chlorination treatment and the reaction is limited to the surface of the fiber without affecting the bulk properties and the dyeability of wool fibers. The continuous aqueous ozone treatment of wool fabric provided excellent shrink-resistance but the top treatment showed poor results [34], [35]. The wool fabric treated with gaseous ozone at 70 °C also produced excellent shrink-resistance [36].…”
