Structure
TECHNICAL PARAMETER
one
It can whiten cellulose effectively in cold water and warm water. High whiteness can be achieved in a short time.
two
It can be widely used in washing powder, washing cream, liquid detergent, fabric softener and finishing agent
three
High fluorescence intensity. The dosage is only 1 / 10-1 / 6 of Das brightener
four
It has bright neutral white light on cotton, polyester cotton, nylon and wool fabrics. It is suitable for whitening of nylon, especially elastic nylon and cellulose fibers. It has excellent fastness.
five
Repeated washing will not make the fabric yellowing or turning green, but the more washing, the brighter. However, DAS brightener can make it green, dark and whiteness decrease.
six
It is suitable for liquid detergent because of its high solubility at low temperature. It has excellent stability and whitening effect in super concentrated liquid detergent and heavy scale detergent.
seven
Because there is no nitrogen in the molecule, it is very resistant to chlorine bleaching, oxygen bleaching agent, strong acid and alkali, and has excellent perspiration fastness. This makes NFW play a very high efficiency in detergent containing bleaching agent.
eight
Excellent dry and wet fastness to sunlight make it more effective in practical use. Most of the DAS brighteners are decomposed by sunlight during the drying process.
nine
It can significantly increase the whiteness of washing powder, soap and soap, and improve their appearance.
ten
Extremely low toxicity ensures high safety to human body during operation and use
