CORE-SHEATH TYPE CONJUGATE SPUN YARN, FABRIC MADE OF THE YARN AND METHOD FOR MANUFACTURING THE YARN

摘要

PROBLEM TO BE SOLVED: To provide an apparatus capable of manufacturing a core-sheath type conjugate spun yarn excellent in homogeneity of properties. SOLUTION: The ring spinning frame has the following construction: two cylindrical bodies (2, 3), and a large diameter-having body and a small diameter- having body both of which are directly connected on the axis of a positively rotationally driving front bottom roller (1), and arranged coaxially for every spindle, and two cylindrical front top rollers are arranged respectively on each of the two cylindrical bodies in an independently rotatable state.
