Aojin Chemical is a professional supplier of sodium dithionite (sodium hydrosulfite powder), offering a stable supply of 88% and 90% industrial-grade product. We support full-container exports and welcome inquiries from clients in the textile and paper industries.
sodium hydrosulfite appears as a white crystalline powder. In Egypt, where the textile industry is well-developed, this chemical is primarily used for the reduction dyeing of cotton fabrics, indigo dyeing for denim, color stripping, and the bleaching of silk and wool. It is also utilized for bleaching wood pulp and deinked pulp, brightening kaolin clay, decolorizing leather, and treating wastewater containing heavy metals. It provides consistent bleaching results and ensures vibrant colors, making it a widely used reducing agent in Egyptian industry.
Key Applications of sodium hydrosulfite:
1. Textile and Dyeing Industry: Used as a reducing agent for vat dyes, a color-stripping agent, and for bleaching silk, wool, cotton, and linen. It is extensively employed in indigo denim dyeing, ensuring bright, color-fast results after bleaching.
2. Pulp and Paper Industry: Used for the reductive bleaching of wood pulp, deinked pulp, and mechanical pulp to enhance brightness—a preferred choice for paper mills.
3. Non-metallic Mineral Processing: Used to brighten kaolin and bentonite by reducing impurities, thereby decreasing yellowness and improving the quality of mineral fillers.
4. Other Sectors: Includes bleaching leather and fur, serving as a reducing agent in chemical synthesis, treating heavy-metal-laden wastewater, and decolorizing bamboo or straw-based products.
