POLYETHYLENE-TEREPHTHALATE FIBERS AND METHOD OF PREPARATION THEREOF

摘要

FIELD: synthetic fibers. SUBSTANCE: obtained fibers are distinguished with improved volume characteristic which is achieved by introducing into polyester 0.05-2 wt % of ester compound of general formula [CH(CH)CO(O-CH-CH)OPh]A where a is C-C-alkylene and 0.01-2 wt % of a nucleating agent. Spinned and stretched fibers in the form of nonwoven material are characterized with both high initial bulking and especially high elasticity after maximum loading. EFFECT: improved performance characteristics.
