A very important reason for salt for direct dyes acceleration effect is to reduce the dyeing process charge effect. The surface potential of the cellulose fibers with a neutral or weakly alkaline dyebath with anionic direct dyes of anhydrous sodium sulphate to produce the electric repulsion, sodium sulfate 99, a large amount of positively charged sodium ions in the electrolyte is added dye , the anionic charge on the holding and neutral dyes, the dyeing process to eliminate obstacles to the dye molecules in close contact with the fiber surface, reducing the dye concentration near the interface and the fiber is poor, thereby increasing the percentage of dye staining. Anhydrous sodium sulfate (Na2SO4) Properties: white fine crystal or powder, soluble in water, hygroscopic neutral sodium sulphate, odorless, non-toxic Uses: Widely used in Vinylon sodium sulfate, sodium silicate, dyeing, synthetic detergent, glass, paper, leather, oil and gas pipelines corrosion, metal smelting, surface treatment, fillers and other industries. Packaging and storage: PE bag lined plastic woven bag, net weight 25kg, 50kg or 1000kg. Should be stored in ventilated, dry coffers. In the summer or high temperature areas prone to melt and form large, storage and transportation should be moisture, rain. Be careful not to be nails or sharp tip edges of a hard object punctured bags caused by product leakage. Do not mix with food, coal, cement, etc. to prevent contamination. When fire, water and a variety of fire extinguishers to fight the blaze. Weifang Rui Desheng Chemical Co., Ltd.
