YUKING Vinylpyrrolidone/vinylimidazole copolymer (VP/VI) for texile industial use

English translation: Vinylpyrrolidone/vinylimidazole copolymer
English abbreviation: VP/VI
Product appearance: Light yellow transparent viscous liquid

Product Details
The VP/VI has a stronger affinity for dye molecules and possesses greater complexing ability. Due to the presence of vinyl imidazole, the water solubility of VP/VI is stronger than that of PVP. It also has good compatibility with other surfactants and excellent salt (potassium metasilicate) resistance. It is suitable for preparing high-performance anti-stain and detergent-resistant products.

Main function: Anti-staining agent for printing and dyeing / washing

Main application
• Use the post-washing agents and soaping agents for reactive dyeing or printing on cellulose fibers and their blended fabrics.
It enables the hydrolyzable reactive dyes to remain in the cleaning bath, ensuring that there is no white ground staining on the printed fabrics or dyed fabrics, and they are not affected by salt, hardness ions and alkali.
• Quickly and efficiently remove unbound hydrolyzed reactive dyes. The post-cleaning process of reactive dyes can be completed in four to five baths. Even at a lower washing temperature, it saves water and energy, thereby reducing the negative impact on the environment and reducing wastewater discharge.

Packaging and Storage
25KG, 200KG / Blue plastic drums; Sealed, stored in a cool and dry place; After opening the container, if the contents are not used up, they should be sealed and stored again. Shelf life: 12 months.
