METHOD OF YARN PRODUCTION Russian patent published in 1997 - IPC

Abstract RU 2081218 C1

FIELD: textile industry. SUBSTANCE: the offered method includes formation of fibrous component from modified polyester fibers of linear density of 0.17-2.0 tex with increased flexibility and reduced rigidity of molecular chains with regulated melting temperature of 210-230 C, preparation of their blend in the amount of 20-98 mas.% with 2-80 mas.% of natural fibers, or their blend with chemical fibers and formation of yarn from blended fibers. Modified polyester fibers has shrinkage of 1.5-2.0% or 20-60%. EFFECT: higher efficiency. 3 cl, 1 tbl
