SLIVER COMPRISING ULTRAFINE FIBER

PROBLEM TO BE SOLVED: To provide a sliver finished in a spinning process, using as a constituent fiber an ultrafine fiber having ≤0.7 dtex single fiber fineness and having approximately the same qualities as those of conventional slivers made of a synthetic fiber. SOLUTION: The sliver comprises a sy...

Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a sliver finished in a spinning process, using as a constituent fiber an ultrafine fiber having ≤0.7 dtex single fiber fineness and having approximately the same qualities as those of conventional slivers made of a synthetic fiber. SOLUTION: The sliver comprises a synthetic fiber carded in a carding process, having ≤30 mm fiber length and obtained by using a fibrillated-type composite yarn having ≤0.7 dtex single fiber fineness and ≥2 segment number in the single yarn, wherein, in a sliver state in which single fibers are collected in an amount of ≥5,000 dtex, U % is ≤10.0% and the number of neps (count/g) is ≤8.0, and wherein the segment is slit along its axis at least randomly.
