Environment-friendly polyester dyeing repair agent and preparation method thereof

Abstract

The invention belongs to the technical field of dyeing and finishing in the textile industry, and relates to an environment-friendly polyester dyeing repair agent and a preparation method thereof. Theenvironment-friendly polyester dyeing repair agent is prepared by blending the following raw materials in percentage by weight: 20-30% benzyl alcohol, 10-20% propyl benzoate, 10-20% of benzyl alcoholpolyoxyethylene ether, 10-20% of fatty alcohol polyoxyethylene ether, 5-10% of Tween-80, 8-15% of tristyrylphenol polyoxyethylene ether, 5-10% of a solvent and 2-4% of an efficient defoaming agent. Compared with the prior art, the environment-friendly polyester dyeing repair agent has the advantages that not only can the level dyeing effect of the polyester fiber dyeing process be improved, colorspots, dying defects and the color difference be prevented, the long-term colorfastness be achieved, the color fading be prevented, and the high elasticity be achieved, but also the coloring rate canbe improved during the use process, the product quality stability can be high, and the abrasion-resistance property can be excellent; and the environment-friendly polyester dyeing repair agent further has the advantages of being low in production cost, achieving energy conservation and emission reduction, and beneficial to environmental protection.

Description

technical field [0001] The invention belongs to the technical field of dyeing and finishing in the textile industry, and specifically aims at the application of dyeing in the textile industry, and provides an environment-friendly polyester dyeing and repairing agent and a preparation method thereof. Background technique [0002] Polyester is an important variety of synthetic fibers. The fibers made by spinning and post-processing have many advantages such as light weight, high strength, good elasticity, good wear resistance, mildew and moth resistance, and are widely used in textiles. industry. The traditional process of polyester dyeing is to dye polyester fibers with disperse dyes in an acidic environment of 130-140 ° C. Since the dyeing process of polyester fibers and dyes is a relatively complicated process, in the post-dyeing stage, disperse dyes are adsorbed on polyester fibers.

The traditional process of polyester dyeing is to dye polyester fibers with disperse dyes in an acidic environment of 130-140 ° C. Since the dyeing process of polyester fibers and dyes is a relatively complicated process, in the post-dyeing stage, disperse dyes are adsorbed on polyester fibers. After that, it will no longer be redistributed, so it is easy to cause irreparable color spots, color flowers, color differences and other defects in polyester fibers, it is difficult to achieve uniform dyeing, and it is easy to cause large areas of color differences in textiles, which cannot be reused. Repairs become genuine products and produce waste products, resulting in a great waste of textiles, which affects the economic benefits of the enterprise
