Abstract
The chapter discusses coloration methods of various synthetic fibres, namely acetate, polyester, nylon, acrylic, polyolefins and elastomeric fibres. These thermoplastic fibres cannot be dyed at ambient temperatures. Dyeing is carried out at a temperature higher than their respective glass transition temperatures. Dyeing may be carried out by exhaust (batch) method or continuous method using dry-heat. The dyes mostly used for dyeing these fibres are disperse, acid and basic dyes.
