Problems solved by technology

However, as the dyeing temperature increases, the dynamic balance begins to be broken, that is, the "adsorption" trend gradually increases, while the "desorption" trend gradually weakens, and the disperse dyes are no longer redistributed after being adsorbed on the polyester fiber. Make polyester fibers have irreparable color spots, color flowers, color differences and other defects

Embodiment Construction

[0017] A kind of environment-friendly repairing agent of the present invention and performance comparison experiment process are further described below in conjunction with embodiment.

[0018] An environment-friendly repair agent is composed of polyoxyethylene ether compounds.

[0019] A performance comparison experiment process of an environmental protection repair agent, comprising the following steps:

[0020] 1) Test materials: environmental repair agent, disperse dye, polyester knitted fabric, glacial acetic acid, high temperature dyeing machine;

[0021] 2) Test process:

[0022] A: Migration

[0023] The microfiber knitted fabric dyed with 1% disperse violet retrieved from the dyeing factory was used as a unified dyed fabric, and the dyed fabric and the dyed fabric were sewn together for a dye migration test. 0.5g / L environmental protection repair agent, bath ratio 1:10, adjust the pH=4.5-5.0 with glacial acetic acid, control the heating rate 2°C / min, and carry out ...

Abstract

The invention belongs to the technical field of textile printing and dyeing processing, and particularly relates to an environment-friendly repairing agent and a performance contrast experiment process. The environment-friendly repairing agent is composed of a polyoxyethylene ether compound. The beneficial effects are that the solubility in water is good and the stability is high; the repairing agent has a swelling effect on fibers and can promote rapid dispersion and uniform permeation of dye in the fibers; the repairing agent has excellent dispersibility and extremely strong migration performance on the disperse dye dispersant and is continuously desorbed to generate obvious migration so that the dye on the cloth cover is uniformly distributed, and thus the ideal reconditioning effect ondyeing defects such as dyeing defects, color spots, streaks and the like formed on fabrics can be realized and the repairing agent is excellent in various fastnesses.

Description

technical field [0001] The invention belongs to the technical field of textile printing and dyeing, and in particular relates to an environment-friendly repair agent and a performance comparison experiment process. Background technique [0002] During the dyeing process of polyester fabrics, due to improper operation or unclean degreasing of fabrics, dyeing defects such as colored flowers, color differences, and stripes will occur, which will cause economic losses to the factory. At present, polyester dyeing refers to the dyeing of polyester fibers with disperse dyes under acidic conditions of 130 °C. In the traditional sense, if there are defects such as color spots, color flowers, and color differences in the process of polyester dyeing, or even more seriously, when there is a large difference in hue, it can only be judged as a waste product because it cannot be repaired into a genuine product. Therefore, Cause great waste of textiles. [0003] During the dyeing process ...
