Effective application of dendrimers in dye industry
1) dendrimers have good performance in promoting cotton fiber dyeing of reactive dyes. After pretreatment of dendrimers, reactive dye dying degree of cotton fabric can be significantly improved, even coloring without strong base and electrolyte. Pretreatment by dendrimers can save a lot of strong base and electrolytes, and unreacted dyes can be recycled. 2) the unique structure and properties of dendrimers shows a good prospect in treating wastewater containing dye. Dendrimers as an efficient decolorization flocculant, has the characteristics of less dosage, wide pH applicable range, high decolorization rate, easy to operate, treated water reusable for high concentrations of dye wastewater with high chroma. For some dye wastewater, decolorization rate can be 98%, COD removal rate could reach 96%, therefore, dendrimers will have a good application prospects in dye wastewater treatment.

Effective application of dendrimers in calcium alginate fiber dyeing.
With the increase of dendrimer generation, dye effect on calcium alginate fibers was gradually increased, dyeing rate reached 43% when dendrimer was the fourth generation.The modified calcium alginate fiber has higher K/S values for reactive dyes. Dendrimer modified calcium alginate fibers washed four times in 40 ℃ distilled water, K/S value reached the stable value, the loss rate of K/S values ​​was about 4%, which indicates that fiber sample has high water resistance fastness.
