Sodium Sulfite Na2SO3 as a Stabilizer for Artificial Fibers

Sodium Sulfite is an inorganic substance with the chemical formula Na₂SO₃. It is a sulfite of sodium and is mainly used as a stabilizer for artificial fibers, fabric bleach, photographic developer, dyeing and bleaching deoxidizer, spice and dye reducing agent, and lignin remover for papermaking.

Reducing bleach has a bleaching effect on food and a strong inhibitory effect on oxidase in plant-based foods. According to Chinese regulations, it can be used for preserves with a maximum usage of 2.0g/kg; 

The printing and dyeing industry, as a deoxidizer and bleach, is used for the cooking of various cotton fabrics, which can prevent local oxidation of cotton fibers and affect fiber strength, and improve the whiteness of the cooked fabric. 
Used for trace analysis and determination of tellurium and niobium, as well as preparation of developer solutions, and also as a reducing agent.

Application

1. Used for trace analysis and determination of tellurium and niobium, as well as preparation of developer solutions, and also as a reducing agent;
2. Used as a stabilizer for artificial fibers, fabric bleach, photographic developer, dyeing and bleaching deoxidizer, flavoring and dye reducing agent, papermaking lignin remover, etc;
3. Used as a common analytical reagent and photosensitive resistor material;
4. Reducing bleach has a bleaching effect on food and a strong inhibitory effect on oxidase in plant-based foods. According to Chinese regulations, it can be used for preserves with a maximum usage of 2.0g/kg; It can also be used for glucose, liquid glucose, sugar, rock sugar, malt sugar, candy, bamboo shoots, mushrooms and canned mushrooms, grapes, blackcurrant concentrate, with a maximum usage of 0.60g/kg. The residual amount (calculated as SO2) of bamboo shoots, mushrooms, canned mushrooms, preserved fruits, grapes, and concentrated black currant juice is ≤ 0.05g/kg; Potato starch residue ≤ 0.03g/kg; The residual amount of biscuits, sugar, vermicelli, and other varieties is less than 0.1g/kg; The residual amount of liquid glucose shall not exceed 0.2g/kg;
5. The printing and dyeing industry, as a deoxidizer and bleach, is used for the cooking of various cotton fabrics, which can prevent local oxidation of cotton fibers and affect fiber strength, and improve the whiteness of the cooked fabric. The photosensitive industry is used as a developer. Organic industry is used as a reducing agent in the production of meta phenylenediamine, 2,5-dichloropyrazolone, anthraquinone 1-sulfonic acid, 1-aminoanthraquinone, sodium aminosalicylate, etc., which can prevent the oxidation of semi-finished products during the reaction process. Used as a lignin removal agent in the papermaking industry. The textile industry is used as a stabilizer for artificial fibers. The electronic industry is used to manufacture photoresistors. The water treatment industry is used for the treatment of electroplating wastewater and drinking water;
6. Used in the food industry as bleaching agents, preservatives, loosening agents, and antioxidants. Also used in pharmaceutical synthesis and as a reducing agent in the production of dehydrated vegetables;
7. Used in the production of cellulose sulfite esters, sodium thiosulfate, organic chemicals, bleached fabrics, etc., as well as reducing agents, preservatives, dechlorinating agents, etc;
