METHOD FOR MANUFACTURING AIR-JET CORE YARN HAVING EXCELLENT ELASTICITY AND FRICTION RESISTANCE

摘要

The present invention relates to a method of manufacturing an air-jet core yarn covering a filament of a core part with any one of cotton, a synthetic fiber, and a regenerated cellulose staple fiber, by inserting a filament yarn having elasticity as a central yarn. By the present invention, it is possible to provide the air-jet core yarn having a clean appearance, evenness, and friction resistance by reducing hairness rather than an existing a ring spinning frame core yarn.;COPYRIGHT KIPO 2020
