SLIVER COMPRISING EXTRA FINE FIBERS

Document Type and Number:

WIPO Patent Application WO/2001/038619

Kind Code:

A1

Abstract:

A sliver comprising extra fine fibers, characterized in that it comprises carded synthetic fibers having a fiber length of 30 mm or less, wherein the fiber is a fibrillated composite fiber having a single yarn fineness of 0.7 dt or less and a number of segments in the single yarn of 2 or more, wherein in a sliver state in which single fibers are collected in an amount of 5,000 dt or more, U % is 10.0 % or less and the number of neps (pieces/g) is 8.0 or less, and wherein the segment is slitted along its axis line at least randomly. The above sliver provides a spun sliver which uses extra fine fibers having a single yarn fineness of 0.7 dt or less as constituent fibers and at the same time has almost same sliver properties as those of a conventional sliver made of a synthetic fiber.
