摘要

PROBLEM TO BE SOLVED: To provide a knitting yarn for sweaters suitable for producing a weft-knitted sweater (stretch sweater) good in stretchability and also excellent in wearing feeling and form stability. SOLUTION: This knitting yarn for the sweater is a doubly covered yarn obtained by doubly winding thermoplastic synthetic fiber filament yarn as the sheath yarn on a rubbery elastic yarn as the core yarn, wherein the rubbery elastic yarn has a PSD value at 140 deg.C (a permanent set deformation after 100% elongation of the elastic yarn followed by dry heat-setting at 140 deg.C for 60 s) of 55-95%.
