Abstract
Approaches to reducing the content of oligomers on the surface of PET fibres are substantiated. The first one is based on reducing surface sorption of oligomers on the fibre by rational selection of textile auxiliaries for dyeing polyester fabric and creating new preparations based on them; the second consists of chemical decyclization of the oligomers by use of catalysts of ammonolysis and hydrolysis in low concentrations. A method of eliminating cyclic oligomers and unfixed dye from the surface of the dyed textile material was developed based on use of aqueous solutions of ammonia in 0.04-0.06% concentration. Technology is created for giving polyester fibres stable antistatic properties, and this significantly reduces its resistivity from 2.8·1014 to 2.68·109Ω.
