POLYESTER CONJUGATE FILAMENT YARN PACKAGE

摘要

PROBLEM TO BE SOLVED: To provide a polyester conjugate filament yarn package which prevents the irregularity of crimps in the package to eliminate sink marks and stripes, thereby obtaining an excellent fabric. SOLUTION: This polyester conjugate filament yarn package is obtained by rewinding a side-by-side type or eccentric sheath-core type polyester conjugate filament yarn having one constituent consisting mainly of polyethylene terephthalate and the other constituent consisting mainly of polytrimethylene terephthalate to have a winding amount of <2 kg. The package satisfies the following (1) to (4): (1) a difference between the stretch elongation rate of the conjugate filament yarn in an outermost layer of the package and the stretch elongation rate of the conjugate filament yarn in an innermost layer of the package is≤5%; (2) the winding hardness of the package is 45-80 degree; (3) the winding width of the package is 10-25 cm; and (4) the winding diameter of the package is 5-30 cm.
