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.
