METHOD FOR DYEING POLYESTER-BASED CONJUGATE FIBER FABRIC AND DYED FABRIC

摘要

PROBLEM TO BE SOLVED: To provide a dyed fabric made of a polyester-based conjugate fiber excellent in levelness.;SOLUTION: When dyeing a fabric composed of a side-by-side type or eccentric sheath-core type conjugated polyester-based conjugate fiber in which at least one layer is a layer containing polytrimethylene terephthalate as a main component, dyeing is carried out in a heat-up control temperature range from 50°C to 105°C carried out when temperature is raised and at ≥110°C dyeing temperature.;COPYRIGHT: (C)2005,JPO&NCIPI
