Performance characteristics:

Fluorescent brightener CXT is currently considered to be an excellent brightener for printing and dyeing, detergents. The introduction of morpholine genes into the brightener molecule improves its performance. It is suitable for whitening cellulose fibers, polyamide fibers and fabrics. The ionization of fluorescent brightener CXT is anionic, and the fluorescent tone is cyan. Fluorescent brightener CXT has good chlorine bleaching resistance, better than VBL and 31#. The best dye bath PH=7~10, the light fastness is level 4. The biggest feature of CXT used in washing powder is: high whiteness, which can meet any dosage requirements of the detergent industry.

Scope of application:

1. Applicable to detergents, added to synthetic washing powders and soaps to make them white.

2. Used for whitening cotton fibers, nylon and other fabrics, it has excellent whitening effects on man-made fibers, polyamides, and vinylons; it also has good whitening effects on protein fibers and amino plastics.

Usage:

The solubility of fluorescent brightener CXT in water is lower than that of brightener VBL and 31#. It can be used with hot water to make a suspension of about 10%. When preparing the solution, use it immediately after preparation. The solution should be kept away from direct sunlight. The dosage of fluorescent brightener CXT in washing powder is 0.1-0.5%, and the dosage in the printing and dyeing industry is: 0.1-0.3%

Packaging:

Packed in iron barrels or paper barrels lined with plastic bags, net weight of each barrel is 25kg.

Notes:

This product should also be stored in a cool, dry and ventilated warehouse, the storage period is two years.
