Since the partially alcoholized PVA contains more acetate groups, and the volume of the acetate group is much larger than the hydroxyl group, there is a large steric hindrance, so that the partially alcoholized PVA cannot form a compact crystal structure. It can only form loose structures with large
The degree of alcoholysis has an effect on the water solubility, viscosity, adhesion and serosity of the slurry.1． Water solubility:PVA with fully alcoholysis is poor in water solubility,for example,PVA with Alcoholysis degree more than 99%(Mole fraction) begin to dissolve when it is heated above 9
Melamine formaldehyde molding compound is made of "melamine formaldehyde resin" as a base material, "Alpha" cellulose as a filler, and added with pigments and other additives. It has the characteristics of water resistance, high temperature resistance, non-toxicity, bright color and convenient moldi

Caustic soda is used in agriculture, industry, medicine, etc. The following is a brief introduction to the application of caustic soda in the textile industry：
1,Excellent color build-up
Caustic soda is used instead of soda ash for fixing, and even if the amount of 1/10 is substituted for soda ash, sufficient color yield can be guaranteed. Inadvertent addition of caustic soda during operation will have no effect on fiber coloration.
2. Wide adaptability in dyes and equipment, good dye reproducibility
Applicable to all kinds of reactive dyes, it has high color yield and reproducibility for reactive dyes of various structures; it is suitable for various equipments, especially in low bath ratio and aerosol dyeing machine, it shows its unique superiority. In the production of cheese yarn, the inner and outer layer difference can be effectively solved.
3,Shorten the dyeing time
Caustic soda is a new type of buffered solid base with less electrolyte and low ionic strength in the dissolution. Therefore, the coloring is slower during the caustic soda addition process, which makes the dye leveling better. Whether dyed dark or light, the caustic soda can be added in about 20 minutes, shortening the dyeing time.
4, Improve the quality of dyed products, reduce the repair rate.
