SPUN YARN AND TEXTILE PRODUCT USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a spun yarn using ultrafine fibers and to provide the spun yarn using polymer alloy fibers as a precursor for feeding the spun yarn. SOLUTION: The spun yarn comprises the polymer alloy fibers in at least a part thereof. The polymer alloy fibers exhibit a sea-island structure in which islands are composed of a slightly soluble polymer and the sea is composed of a readily soluble polymer in 10-90 wt.% blending ratio of the readily soluble polymer. The number-average diameter of the islands is 1-500 nm. COPYRIGHT: (C)2008,JPO&INPIT
