Disperse leveling agent for dyeing polyester fibers and method for manufacturing polyester fiber dyed products using the same

Abstract

This invention provides a dispersible leveling agent and a method for manufacturing polyester fiber dyed products using the same. This dispersible leveling agent, during high-temperature and high-pressure dyeing of polyester fibers using disperse dyes, exhibits good oil removal properties even when dyeing fabrics that have not been adequately scouring and retain residual oil, and prevents dye aggregation, enabling spotless and uniform dyeing. In one embodiment, this invention provides a dispersible leveling agent for dyeing polyester fibers, comprising: a glycerol monofatty acid ester (A), an ester compound having a specific structure of a polyoxyalkylene group and / or a glycerol group (B-1), and a hydroxyl compound having a specific structure of a polyoxyalkylene group and / or a glycerol group (B-2).
