Problems solved by technology

Photocatalyst materials can be used in many fields at present. Applying photocatalyst fibers to the knitting and weaving industry can endow fabrics with good sterilization and health care properties. At present, scientific researchers have developed photocatalyst fibers. When applying photocatalyst fibers to textiles In the field of fabrics and other fields, there is a complex relationship between the dyeing and finishing technology and the final function and wearability of the fabric during the processing process of photocatalyst knitwear. However, the current research basically stays at the exploratory stage and cannot be industrialized. Production

[0029] A. Preparation of photocatalyst fabric:

[0030] The dyeing and finishing process of photocatalyst fabrics, the dyeing and finishing process is to dye and finish the original cloth (fabric) sequentially according to the following steps: singeing → desizing → bleaching → pre-soaping → cationic dyeing → reactive dyeing → post-soaping Washing→softening→heat setting→finished product inspection→rolling→warehousing.

[0031] The specific process parameters are set as follows:

[0032] Wrap the raw fabric on a chilled roll for dyeing and finishing. The speed of the chilled roll is 120m / min. Singeing is performed in a positive and negative manner, and the singeing flame temperature is controlled at 900°C. Desizing is refined with biological enzymes and hydrogen peroxide. After bleaching, refining and rinsing, rinse with water, first rinse with 80°C water, then rinse with 50°C warm water; the pre-soaping liquid is M-260, the concentration is 2 wt %, and the pH value is 7~8 neut...

Embodiment 2

[0055] The setting of this embodiment is the same as that of Example 1, the difference is that: the washing temperature of pre-soaping is 85°C, and the washing time is 25 minutes; the washing temperature of post-soaping is 85°C, and the washing time is 40 minutes; the cationic dye is red X -GRL, the reactive dye is Anoxol Dye Crimson L-4B, the softening temperature is 45°C, soaked for 55 minutes, and the liquor ratio is 4%.

Embodiment 3

[0057] The setting of this embodiment is the same as that of Example 1, the difference is that: the washing temperature of pre-soaping is 80°C, and the washing time is 25 minutes; the washing temperature of post-soaping is 85°C, and the washing time is 40 minutes; the cationic dye is black X -RBL, the reactive dye is Anoxol dye Zhiqing L-3G, the softening temperature is 50°C, soaked for 60 minutes, and the liquor ratio is 5%.

[0058] B. Characterization of Photocatalytic Fabrics

[0059] 1. Antibacterial performance test

[0060] Put the 1# control sample (pure cotton), 2#~5# samples and blank samples into conical flasks with a certain concentration of test bacteria liquid, vibrate at a specified temperature and frequency for a certain period of time, and extract each conical flask. Dilute a certain volume of bacterial liquid in the bottle and put it into a petri dish for culture after dilution by a million times; after a certain period of time, count the number of colonies...

Abstract

The present invention discloses a photocatalyst fabric dyeing and finishing process, and belongs to the technical field of textile fabric processing. According to the process, an original cloth (fabric) is subjected to dyeing and finishing sequentially according to the following steps: singeing, ?desizing, ??bleaching, pre-soaping, ??cation dye dyeing, active dye dyeing, post-soaping, a soft treatment, ?heat setting, finished product inspection, winding and warehousing. With the dyeing and finishing process, the multifunctional photocatalyst knitwear with characteristics of good wearing performance, bacterial resistance, ultraviolet resistance, deodorization, and static electricity resistance can be obtained, and the process can be applicable for textile fabric processing and post-treatment processes.

Description

technical field [0001] The invention provides a photocatalyst fabric dyeing and finishing process, which belongs to the technical field of fiber product treatment. Background technique [0002] Knitted products, as people's personal products, directly contact our skin. In addition to the conventional functions of covering the body and keeping warm, it also extends the function of health. Therefore, our positioning of knitwear is 24-hour skin care textiles that are beneficial to health, which is also the direction of the future development of the knitting industry. [0003] At present, knitting enterprises are facing various development pressures such as rising raw material prices, labor shortages, and rising labor costs. They need to develop and produce functional knitwear, increase the proportion of high-end knitwear, and then improve product added value and market competitiveness. It can be seen that the research and development of new functional knitting products has imp...
