Abstract

Treatments of polyamide 6, Quiana and Nomex fabrics with β- Cyclodextrin(CD) or monochlorotriazinyl β- Cyclodextrin(CD-T) were investigated. Significant improvements in antimicrobial and thermal stability uniformity were observed. The colour values and fastness of the coloured fabrics to washing and perspiration were given. The untreated and treated fabrics were characterized by infrared spectroscopy (FTIR), differential thermal analysis (DTA) and thermogravimetric analysis (TGA). The changes in yellowness, moisture regain, roughness, tensile strength, elongation and antimicrobial activity have been studied. The TGA indicated that the temperature of burning Tb value lies at 471oC- 472oC for CD treated polyamide 6 while it lies at 475oC-490oC for CD-T treated one. This may afford the use of CD-T in treatment of polyamide 6 to attain also some heat resistance than untreated one.
