1. Bleaching Powder
It is hypochlorite of calcium and sodium. Bleaching powder on treatment with small quantities of dilute acid liberates hyopchlorous acid, whcih can easliy furnish nascent oxygen and thus acts as an oxidizing and bleaching agent. It is used for the following purposes:
1. As an oxidising agent in garment processing
2. For bleaching cotton, linen and wool.
3. In rendering wool unshrinkable.
2. Hydrogen Peroxide, H2O2
Hydrogen peroxide is a colorless, odorless, syrupy liquid in the anhydrous state. It is a powerful oxidizing agent. It destroys the color of some organic compounds and is used in garment and textile industry for bleaching delicate fabrics like wool, straw and silk.
3. Potassium Chlorate KClO3
Potassium chlorate is a white crystalline solid, which is soluble in water. On heating it decomposes to give oxygen. The ease with which it can lose oxygen, it acts as a strong oxidizing agent. It is used for garment printing.
4. Potassium Chromate
Potassium chromate is available in the form of lemon yellow crystals with no water of crystallization. In garment industry it is used as a mordant.
5. Potassium Dichromate
It is available in the form of orange red crystals. It is soluble in water. In neutral or acidic solution, potassium dichromate furnishes nascent oxygen and thus acts as an excellent oxidizing agent. It is used in garment industry as an oxidizing agent and as mordant in dyeing.
6. Potassium Permanganate
It acts as a powerful oxidising agent in neutral, alkaline or acidic solution and hence used in the garment industry as an oxidising agent.
7. Sodium Perborate
Sodium perborate is mainly used as a bleaching agent for a variety of fabrics namely wool, cotton, rayon, linen etc. It is also used as an oxidising agent and dye fixing agent.
8. Sodium Hypochlorite
Sodium hypochlorite liberates hypochlorous acid and thus acts as a powerful oxidizing and bleaching agent. It is used in textile and garment industry for bleaching process.
9. Sodium Bisulfite, NaHSO3
An aqueous solution of sodium bisulfite is obtained when an aqueous solution of sodium carbonate is saturated with sulphurdioxide. It is an important reducing agent and is used as an antichlor after bleaching garments with chlorine.
10. Sodium Hydrosulfite
It is used as reducing and bleaching agent in garment and textile industry.
11. Sodium Metabisulfite
On heating, it decomposes into sodium bisulfite and sulfur dioxide and hence it is an important reducing agent. It is used as an antichlor after bleaching garments with chlorine.
12. Sodium Sulfite
It forms colorless crystals very soluble in water. It is decomposed by dilute mineral acids with the evolution of sulfur dioxide. It is used as mild bleaching agent for silk and woollen fabrics and as an antichlor after chlorine bleach.
13. Sodium Sulfide
Its aqueous solution shows and alkaline reaction due to hydrolysis. It is used for manufacture of sulfur dyes and as reducing agent in garment industry.
14. Sodium Sulfoxylate Formaldehyde
It is also known as Rongalite C. It is a powerful reducing agent and exerts its full reducing action only at high temperatures. It finds extensive application in garment and textile industry for printing and stripping dyed fabric prior to re-dyeing.
15. Sodium Thiosulfate
It is also know as hypo. It is a colorless, crystalline and efflorescent substance. It is used as an antichlor after bleaching garments with chlorine.
16. Stannous Chloride: It is used as mordant in garment dyeing and printing.
17. Dextrin
It is a modified starch prepared by heat treatment of starch in the dry state, with or without the addition of small quantities of chemicals. It is a white powder, and finds extensive use as sizing and finishing agent.
18 Glucose
It acts as a strong and cheap reducing agent in garment industry.
