Embodiment 1

[0031] A new dyeing and finishing process for polyester fabrics, which sequentially includes four steps of pretreatment, presetting, dyeing and postsetting. The dyeing steps include dye liquor preparation, dye liquor heating and heat preservation, dyeing, drying and The five-step operation of color fixing, in the dye liquor preparation operation, add dye, retarder, color fixing agent and softener, and the color fixing operation uses steam heating to achieve color fixing.

[0032] Carry out the following preparation by weight in the described dye liquor preparation operation: Retarding agent 0.20g / L; Fixing agent 0.10g / L; The pH was adjusted to 4.0 by dropwise addition of glacial acetic acid. The retarder is an amine salt cationic surfactant, such as N, N-diethylethylenediamine, and the color fixing agent is a cationic quaternary ammonium salt polymer, such as dimethyl diallyl Ammonium chloride polymer, the softener is a cationic long-chain aliphatic softener, such as emollien...

Embodiment 3

[0051] A new dyeing and finishing process for polyester fabrics, which sequentially includes four steps of pretreatment, presetting, dyeing and postsetting. The dyeing steps include dye liquor preparation, dye liquor heating and heat preservation, dyeing, drying and The five-step operation of color fixing, in the dye liquor preparation operation, add dye, retarder, color fixing agent and softener, and the color fixing operation uses steam heating to achieve color fixing.

[0052] Carry out the following preparation by weight in the described dye liquor preparation operation: Retarding agent 0.25g / L; Fixing agent 0.15g / L; The pH was adjusted to 4.3 by dropwise addition of glacial acetic acid. The retarder is an amine salt cationic surfactant, such as N, N-diethylethylenediamine, and the color fixing agent is a cationic quaternary ammonium salt polymer, such as dimethyl diallyl Ammonium chloride polymer, the softener is a cationic long-chain aliphatic softener, such as emollien...

Abstract

The invention belongs to the technical field of textile fabrics, and particularly relates to a novel dyeing and finishing technology for polyester fabrics. According to the technology, dyeing sequentially includes the steps of dye liquor preparation, dye liquor heating and heat preservation, dyeing, drying and color fixation, and the effect of effective dyeing is achieved. The technology has the advantages that the dyeing step is reasonable and effective, the color fastness of dyes after dyeing is high, the fabrics are not likely to fade after long-time use, the sectional type steam fixation effect is good, and the color fastness is further improved.

Description

technical field [0001] The invention belongs to the technical field of textile fabrics, in particular to a novel dyeing and finishing process for polyester fabrics. Background technique [0002] Polyester fabric refers to a kind of chemical fiber clothing fabric made of polyester fiber. It has the advantages of good wrinkle resistance and high shape retention, so it is mostly used in various outerwear fabrics. The dyeing and finishing process of polyester fabrics is generally the same as other fabrics, generally including four steps of pretreatment, pre-setting, dyeing and post-setting, but the dyeing steps in the prior art all have a certain degree of insufficient color fastness, which eventually causes Fabrics fade in a relatively short period of time, so a new dyeing and finishing process with high color fastness and long-term use that is not easy to fade is urgently needed in the market. [0003] The patent publication number is CN 109440502A, and the Chinese invention ...
