Embodiment 1

[0016] An anti-yellowing finishing process for light-colored fabrics. Four optimized anti-yellowing finishing processes are added to the dyeing and finishing process of ordinary light-colored fabrics. The second is to carry out the anti-yellowing soaking process before soaping, the third is to carry out the anti-yellowing same-bath process at the same time as the last water washing process, and finally carry out the anti-yellowing finishing process in the heat setting process;

[0017] The simultaneous anti-yellowing process of the dyeing process and the washing process is to add the anti-yellowing auxiliary agent AY, leveling agent and citric acid with a mass ratio of 4:1:1 while dyeing, and the bath ratio is 1 : 15, the pH is 4.5, the temperature is 80°C, and the time is 50min;

[0018] The anti-yellowing soaking process before the soaping is to add the anti-yellowing auxiliary agent AY, citric acid, and water to soak for 20 minutes, the pH is 4.5, and the temperature is 50°...

Abstract

The invention discloses an anti-yellowing finishing process for light-colored fabrics. The anti-yellowing finishing process is implemented by adding an optimized anti-yellowing finishing process for four times in processing, dyeing and finishing processes of common light-colored fabrics, specifically, firstly, carrying out an anti-yellowing one-bath process simultaneously a dyeing process is performed, secondly, carrying out an anti-yellowing soaking process before soaping is performed, thirdly, carrying out an anti-yellowing one-bath process while the last washing process is performed, and finally carrying out an anti-yellowing finishing process in a heat setting process. The optimization of the four-time anti-yellowing finishing process effectively reduces the probability of yellowing of the light-colored fabrics, so that finished fabric products are balanced in color; the anti-yellowing finishing process for the light-colored fabrics disclosed by the invention has the advantages of environmental friendliness and high quality, and has strong practicability.

Description

technical field [0001] The invention relates to a fabric processing technique, in particular to an anti-yellowing finishing technique for light-colored fabrics. Background technique [0002] White or light-colored fabrics such as nylon and elastic fibers and blended fabrics are prone to yellowing. Yellowing may occur during the dyeing and finishing process, or may occur during storage or hanging in shop windows, or occur There are many reasons why yellowing can occur during seasonal storage at home, such as chemicals used in fabrics, processing conditions in dyeing and finishing processes, packaging and storage conditions, etc. At present, no effective solution has been proposed to prevent and alleviate the yellowing phenomenon of light-colored fabrics. [0003] Therefore, a new technical solution is needed to solve the above problems. Contents of the invention [0004] Purpose of the invention: In order to solve the problems in the prior art, the present invention provi...
