PRODUCTION OF LOW THERMALLY SHRINKABLE THICK AND THIN COMPOSITE YARN

PURPOSE: To obtain a base yarn capable of obtaining a large thermal contraction difference, when processed into a differently shrinkable blended yarn, because of having a soft touch not having been obtained from conventional multifilament yarns and a specific dyeing property due to the thick and thi...

Zusammenfassung:	PURPOSE: To obtain a base yarn capable of obtaining a large thermal contraction difference, when processed into a differently shrinkable blended yarn, because of having a soft touch not having been obtained from conventional multifilament yarns and a specific dyeing property due to the thick and thin shape, and further because of having a low thermal shrinkage degree. CONSTITUTION: The method for producing the low thermally shrinkable thick and thin composite yarn comprises spinning a fiber-forming polymer and a polymer having higher solubility than that of the fiber-forming polymer through a spinneret into the undrawn composite multifilament yarn wherein the fiber- forming polymer is divided into plural segments containing ultrafine segments of
