Abstract

The invention discloses a novel polyester fiber dyeing composition. The novel polyester fiber dyeing composition is prepared from, by mass, 10-60 parts of disperse dyes, 10-40 parts of alcohol compounds, 5-10 parts of unsaturated fatty acid, 5-40 parts of hydrophobic compounds, 1-4 parts of dispersant, 1-8 parts of levelling agents, 3-10 parts of surfactants and 10-300 parts of water. The novel polyester fiber dyeing composition has super light fastness and discoloration avoiding performance under the high-temperature condition, so that fabric dyed with the dyeing composition has excellent washing fastness after heat setting or soft finish is carried out and is easy to color and bright in color, and colors of the fabric are abundant.

Description

technical field [0001] The invention relates to printing and dyeing auxiliaries, in particular to a novel polyester fiber dyeing composition. Background technique [0002] At present, the types of fibers on the market are becoming more and more abundant. New polyester fibers mainly include polylactic acid fibers, etc., which are the main source of fibers for textiles. The requirement of high standard of color fastness has become an urgent need in the market. Among the new polyester fibers used in textiles and clothing, polyester fibers based on polyethylene terephthalate have the fastest growth rate. The dyeing performance and color fastness of existing disperse dyes cannot meet the requirements of new polyester fibers. . [0003] Therefore, a new technology is needed to solve the above problems. Contents of the invention [0004] Purpose of the invention: In order to solve the problems in the prior art, the present invention provides a novel polyester fiber dyeing comp...
