Cotton chlorine-resistant fixing agent DS-1319
Textile printing and dyeing industry require increasingly color fastness of the chlorine-resistance for reactive dyes, Which promote research on improving chlorine fastness by using fixing agent. Europe, America, Japan and other countries have introduced special cationic polymers to improve the color fastness of reactive dyes with a view to improving chlorine-resistance of reactive dyes, They had applied for patents as well later, Desheng Fine chemical are the first manufacturer in China who developed a new kind of fixing agent DS-1319, A excellent chlorine-resistance with high quality fixer on the basis of long term research on the production of color fixing agent
The study show that the fixation of reactive dyestuffs with DS-1319 not only attain excellent washing fastness of dyed fabrics and but also obtain the color fastness of excellent chlorine-resistance of dyed fabric notably through the interaction between reactive chlorine and the fixing agent on reactive layer by covalent bond notably
Property and benefits:
1/The fastness to soaping and dry and wet rubbing can be improved by about 1 grade when used in the post-treatment fixation of cotton fabric after dyeing.
2/The fabric treated with chlorine-resistant fixing agent can improve the fastness to sunlight by about 1 grade, and the fastness to chlorine bleaching is up to more than 4 grades
3/This product is a color fixing agent of non-toxic, Free of phosphorus and APEO, It can reduces waste water pollution easily.
