Textile bleaching and dyeing: In the textile industry, ZFS is commonly used as a bleaching and reducing agent for the bleaching and dyeing process of natural fibers such as cotton, linen, silk, and wool. Due to its reducing performance, it can help remove natural pigments from fibers, making them easier to color.
Printing process: ZFS is also very important in textile printing, especially in reduced dye printing. It can be used as a reducing agent to help fix dyes onto fibers, thereby improving the quality and durability of printing.
Dye manufacturing: In the preparation process of certain dyes, ZFS is used as a reducing agent to synthesize specific dyes, especially those that require a reduction step to form the final color.
Rubber Industry: ZFS is used as a vulcanization promoter in the rubber industry to help improve the processing performance of rubber and the physical properties of the final product.
Paper industry: In the papermaking process, ZFS can be used as a bleaching agent to help remove pigments from pulp and improve the whiteness and brightness of paper.
Cleaning and maintenance products: ZFS is also used in certain cleaning and maintenance products, such as certain special laundry detergent, bleach, and other cleaning agents, to remove stains and bleach.
Chemical synthesis: In organic synthesis, ZFS can be used as a reducing agent in the synthesis process of specific compounds.
