High Purity Trisodium Phosphate Na₃PO₄·12H₂O For Industrial
Riel chemical Trisodium phosphate is an important chemical additive in the textile industry, which is widely used in many production processes because of its basic, complexation and dispersibility properties. The following is its main role in the textile industry and detailed description:
1. Desizing and refining (pretreatment)
Desizing: During fabric weaving, warp yarns are usually starched (such as starch, PVA, etc.) to increase strength. The alkaline solution of trisodium phosphate can effectively dissolve the slurry, make it dissolve and fall off, and prepare for subsequent dyeing and printing.
Refining and removing impurities: Remove natural impurities (such as wax, pectin, protein) in cotton fiber, the strong alkaline of trisodium phosphate can saponify oil, and cooperate with other additives (such as surfactants) to improve the gross effect and fabric cleanliness.
2. Soft water and complex metal ions
Water softness agent: if the textile processing water contains calcium and magnesium ions (hard water), it is easy to form insoluble substances with dyes or soap, resulting in stains or rough touch. Trisodium phosphate can form a soluble complex with these ions and prevent precipitation.
Metal ion blocking agent: in bleaching (such as hydrogen peroxide bleaching), trisodium phosphate can complexate metal ions such as iron and copper, prevent their catalytic degradation of fibers or bleaching agents, and improve bleaching stability.
3. Dyeing and printing assistance
pH regulator: maintain the alkaline environment of dyeing bath or printing paste to ensure that the fixation reaction of certain dyes (such as reactive dyes) proceeds smoothly.
Dispersion and anti-fouling: prevent dye aggregation and improve leveling; In the post-printing treatment to help the unfixed dye wash away, reduce the white dirt.
4. Washing and finishing
Detergent components: trisodium phosphate is often combined with soap and synthetic detergents to enhance detergency, especially emulsifying and dispersing effects on oil and granular dirt.
Neutralization of acid residues: used to neutralize residual acids after pickling or bleaching to avoid equipment corrosion or fabric damage.
5. Boiler and equipment maintenance
Anti-scaling agent: adding trisodium phosphate to boiler water in textile mill can prevent scale deposition, improve thermal efficiency and prolong equipment life.
