Abstract

Polyester knit-fabrics were treated by argon-helium plasma at room temperature and ambient pressure, subsequently graft-polymerized with acrylic acid in vapor. Plasma interaction to the polyester fibres and graft-polymerization of carboxyl functional groups were investigated. Finally, the polyester knit-fabric grafted with carboxyl groups were treated with cationic direct dyes at around 800C and ambient pressure. Results obtained show that grafted surface of the knit fabrics was dyed with the red color, and then their color surface becomes dark pink while their untreated surface has pinkish white. The graft polymerization of the carboxyl groups and the absorption of cationic direct dyes will be discussed in details. Keywords: plasma-induced graft-polymerization, polyester-fiber knit-fabrics, cationic direct dyes, polyester
