Abstract

Worsted corona discharge was under operation, while the operation conditions were optimized. Processed woolen surface properties such as water absorption and staining properties were investigated. In addition, the bending length, wrinkle recovery and tensile strength retention (%) of treated samples were evaluated. Corona discharge after operation worsted water absorption property increased and the staining became high. The scanning electron microscope (SEM) showed that a number of scales on the surface epicuticle wool have dropped. The fourier transform infrared (FT-IR) analysis indicated that the rate of oxygen levels of wool increased and the rate of sulfur decreased after the operation.

Key words: Corona discharge, wool fabric, surface properties, SEM, absorption.
