Embodiment 1

[0018] A coloring masterbatch for improving the vividness and tinting strength of polyester fibers involved in this embodiment includes 20% of pigment, 5% of ethylene acrylate copolymer, 2% of dispersant, and the balance is carrier resin. The carrier resin is PET. The dispersant is prepared by mixing polyethylene wax and simethicone in a ratio of 4:1. Ethylene acrylate copolymer has polar groups at both ends, one end can be combined with polyester molecules, and the other end can be combined with pigments. It can improve the binding ability of polyester molecules and pigments.

Embodiment 2

[0020] A coloring masterbatch for improving the vividness and tinting strength of polyester fibers involved in this embodiment includes 25% of pigment, 7% of ethylene acrylate copolymer, 3% of dispersant, and the balance is carrier resin. The carrier resin is PET. The dispersant is ethylene-vinyl acetate wax.

Embodiment 3

[0022] A coloring masterbatch for improving the vividness and tinting strength of polyester fibers involved in this embodiment includes 25% of pigment, 5% of ethylene acrylate copolymer, 2% of dispersant, and the balance is carrier resin. The carrier resin is PET. The dispersant is a mixture of polyethylene glycol and ethylene-vinyl acetate wax in a ratio of 1:1.

Abstract

The invention discloses a coloring masterbatch for improving the vividness and tinting strength of polyester fiber, which comprises 20-30% of pigment, 5-10% of ethylene acrylate copolymer, 2-5% of dispersant, and the balance is carrier resin. The present invention relates to a kind of coloring masterbatch that improves the brightness and coloring strength of polyester, which uses pigments and ethylene acrylate copolymers, so that the brightness and coloring strength of polyester fibers using the coloring masterbatch can be improved, so that The brightness of polyester fiber is increased by 20%, while the spinning stability is improved, the pressure is stable, the spinning cycle is increased by 20%, and in the process of cleaning components, there are less residues, cleaning is more convenient, and cost and energy consumption are significantly reduced.

Description

technical field [0001] The invention relates to the technical field of masterbatches, in particular to a masterbatch for improving the brightness and coloring power of polyester fibers. Background technique [0002] At present, fiber materials have become one of the fastest-growing and most active fields of science and technology in the world. Among them, the improvement and industrialization of key basic material technologies in the field of chemical fibers is to promote high-performance composite materials, advanced structural materials, new functional materials, and green fibers. An important step in the development of materials. Among them, the dope dyed fiber is obtained by adding a colorant (masterbatch) to the spinning solution or melt, and the colored fiber is obtained by spinning, which saves the dyeing process, reduces waste water discharge, and has outstanding environmental friendliness. At present, the output of dope dyed fiber in my country is about 4.5 million...
