WOVEN OR KNITTED FABRIC AND INITIAL YARN FOR POLYAMIDE SHEATH-CORE TYPE BLENDED YARN

摘要

PROBLEM TO BE SOLVED: To obtain a woven or knitted fabric having a large difference in yarn length that cannot be obtained from a woven or knitted fabric comprising a conventional polyamide blended yarn and to provide a woven or knitted fabric having an excellent feeling and excellent physical properties in which polyamide yarns having different shrinkage stresses are blended and used for a woven or knitted fabric to develop a difference in shrinkage stress even at a low temperature.;SOLUTION: The woven or knitted fabric comprises polyamide sheath-core type blended yarns at least in a part of the woven or knitted fabric. A difference in yarn length between a polyamide multifilament yarn A constituting a sheath yarn of the blended yarn and a polyamide multifilament yarn B constituting a core yarn is 10% or more. The polyamide multifilament yarn A constituting the sheath yarn substantially does not have a loop. It is preferable that the polyamide multifilament yarn A has a single fiber fineness of 1.4 dtex or less, the polyamide multifilament yarn B has a single fiber fineness of 0.9-3.0 dtex, and the polyamide multifilament yarn A is a false-twisted yarn.;SELECTED DRAWING: None;COPYRIGHT: (C)2018,JPO&INPIT
