METHOD FOR PRODUCING ELASTOMERIC COMBINED BULK YARN

摘要

FIELD: textile industry. SUBSTANCE: method involves combining at least two components in the form of ready yarn of natural filaments having ultimate length with twist factor of 27-30 and complex chemical thread with twist factor of 0.1-5; providing joint twisting of combined components, with secondary twist factor being within the range of 18-30; bulking the yarn by selecting twist factors within mentioned values to provide opposite directions of residual twisting of components; selecting linear density values of combined components to provide chemical and natural filaments percentage within the range of 4.5-55%. Selection of twist factors within the limited ranges and in predetermined succession allows new types of elastomeric bulk yarn with increased elastic deformation to be produced. Articles manufactured from such yarn possess increased wear-resistance, crease-resistance, form constancy, hygienics etc. EFFECT: increased efficiency and improved quality of yarn and articles made from such yarn.
