1. Introduction of bentonite
Bentonit, metalik olmayan bir mineraldir. montmorillonit as the main component. Bentonite reserves of China rank first in the world, and it is known as “universal kil” for its diverse properties. The properties include: non-toxicity, no chemical pollution, strong adsorption, hygroscopicity, expansion and lubricity, etc. In textile printing and dyeing industry, with unique physical and chemical properties, bentonite has shown significant advantages in anti-dyeing and color fixing.
2. Effects of anti-dyeing and color fixing of bentonite
● Effect of anti-dyeing
In terms of anti-dyeing performance, bentonite, with excellent adsorption property, can effectively adsorb and fix dye molecules. This can prevent the dye from diffusing to non-target areas during printing and dyeing process, thereby achieving precise pattern printing and color control. Especially in multi-color printing and dyeing process, bentonite can ensure clear boundaries between colors, avoid mutual penetration of colors, and improve color purity and clarity of printed products.
● Effect of color-fixing
Bentonite also plays an important role in color-fixing performance. Due to its layered structure and ion exchange property, bentonite can form a stable bond with dye molecules, and then enhance the adhesion and durability of dyes on fibers. This not only improves the color fastness of printed and dyed products, making them less likely to fade during daily use and washing, but also improves the softness, improving the overall quality of the products.
In addition to anti-dyeing and color-fixing effects, bentonite also has good dispersibility and rheological properties, and it can form a uniform coating or slurry during printing and dyeing process, improving the coverage and uniformity of products.
3. Application prospects of bentonite in printing and dyeing industry
With the improvement of environmental awareness and the advancement of printing and dyeing technology, the application of bentonite in printing and dyeing industry will be further expanded. The application prospects of bentonite in printing and dyeing industry will become increasingly broad.
Before being used in printing and dyeing, bentonite needs to be purified, crushed and graded to improve its dispersibility and stability. After deep processing, bentonite has higher montmorillonite content, fewer impurities, finer particle size and more stable chemical properties. All these are helpful for bentonite to play a better role in textile printing and dyeing industry.
