Different Types of Chemicals Used in Garment Washing Plant



Today’s textile industry uses a variety of chemicals to clean clothes and fabrics, depending on the level of treatment. In particular, the washing of denim products is now an essential process in the production of casual wear fashion items. Laundering of clothes with or without mottling is done to produce effects such as color fading, creases, seam creases, fuzzing, shedding, softer hand, and stable dimensions. is a very important part of different types of chemicals used in different stages to get the right cleaning effect. Chemicals with specific parameters, amounts, and conditions give these clothes a different look. Here are some common chemicals used in laundry facilities.

Garment-washing chemicals and their functions are described below:

1. Enzyme:

The action of the enzymes during the enzymatic wash hydrolyses the cellulose. First, it attacks and hydrolyses protruding fibres. It then attacks the thread content of the fabric and partially hydrolyses the thread content. As a result, the color will come out of the threads, creating a fading effect.

2. Detergent:

The chemistry is a fatty alcohol polyglycol ether in an aqueous glycol solution. Detergents are widely used for continuous and discontinuous pre-treatment of all types of fibers and their mixtures. For removing stains, oil spills, and sizing clothes.

3. Acetic Acid:

Acetic Acid is used to neutralize the garments from the alkaline condition and to control the pH value in the wash bath.

4. Wetting Agent:

Wetting agents are chemicals that lower the surface tension of liquids. In general, liquid molecules try to bond together, causing surface tension. Wetting agents stretch these bonds and reduce the tendency of molecules to stick together, making it easier for liquids to spread over solid surfaces.

5. Desizing Agent:

A Desizing agent is used to remove mainly starches, CMC, waxes, fats pectin, minerals, and unfixed indigo dye from denim, twill, poplin and canvas fabrics etc.

6. Hygroscopic Agent:

Moisture absorbers are substances that easily absorb moisture from the natural world. If the environment becomes wet, this remedy can be used to avoid excess moisture from clothing. Examples: Calcium chloride, amylopectin, etc. Active ingredients that easily absorb moisture from nature are called hygroscopic active ingredients. If the environment becomes wet, this remedy can be used to avoid excess moisture from clothing. Examples: calcium chloride, amylopectin, etc.

7. Whitening Agent:

Chemicals that whiten clothes after use are called whiteners. Basically, this chemical was used on white clothes to make them whiter. Like optical brighteners, 4bk and others are whitening agents. When you use optical brighteners, the brightener molecules stick to your clothes. When light hits the clothes, the molecules emit light, making the clothes appear white and bright.

8. Antistain:

Resists or Antistains are used to prevent stains on the weft (white) threads of denim, white pockets of clothes, solid colors, and touched clothes and to increase the lustre of the fabric. It also works as an anti-wrinkle agent.

9. Bleaching Powder:

Bleaching powder is an oxidizing agent. It is used in washing plants for color out from denim garments. We can achieve different shades of color on garments i.e. Dark, Medium, and Light shade.

10. Sodium Hyposulphite:

Sodium hyposulphite is used to neutralize the garments from chlorine bleach.

11. Caustic Soda:

Caustic created the role in bleach technique without color change the garment and has good cleaning power. It works as fading affect/old looking effect come rapidly on garments.

12. Soda Ash:

Soda ash creates an alkaline medium for the breakdown of pigment dye. Soda ash help to uniform bleaching action on bleach bath. It has a cleaning power and helps the color fading effect of the garment. It is used also for color fixing in the dye bath.

13. Sodium Bicarbonate:

Sodium bicarbonate is used in washing plant in the bleach bath with bleaching powder for Denim Light shade because easily color out within a short time. As a result production increases and costing are low.

14. Potassium Permanganate:

Potassium permanganate is used in the Acid wash with Punic stone for color out from the garments. It is used also spray chamber by nozzle for color out (whitish effect) from the garments.

15. Flax Softener (Cationic, nonionic):

Softener is used to make the garments treated textiles a surface feel that is both sickly and soft and also provides excellent lubricating properties.

16. Micro Emulsion Silicon:

Amino Silicon is a textile finishing agent consisting mainly of amino-modified silicon. When applied on fabrics, it gives durable softness, lubricity, elastic handle, anti-pilling, dimensional stability, and tear resistance, and fabric to be cut and sewn more easily allows and improving wear and easy care properties.

17. Sodium Chloride (Salt):

It helps to exhaust dye into the fiber

18. Buffer:

Buffer is used in washing plants for pH control of enzyme bath, softener bath, and desizing bath.

19. Hydrogen Peroxide:

Hydrogen peroxide creates a prime role in the bleach wash technique. In an alkaline medium, hydrogen peroxide breaks up and gives some per hydroxyl ion, which discolors the coloring materials, and as a result fading effect is developed. Hydrogen peroxide is used in scouring, and bleaching baths for white/ready-for dyeing of gray fabric garments. It is used also neutralized the garment from the alkaline condition.

20. Stabilizer:

Hydrogen peroxide works a good conditioner and stabilizer at a temperature above 90°C, when the temperature rises to 90°C then it breaks into hydrogen and oxygen. The stabilizer is used to protect the breaking of hydrogen peroxide and peroxide works in the bath smoothly.

21. Fixing Agent:

The fixing agent is used for the unfixed dye to fix on fabrics, when fabric color will be proper fixing then color fastness and rubbing fastness will be increased.

22. Catanizer:

Catanizer is used in pigment exhaust method processing. The pigment is color that is not a dyestuff. Pigment colors have no affinity to the fabric thus catanizer is used in fabric to increase the affinity between pigment color and fabrics.

23. Optical Brighteners:

Two types of optical brighteners are used in the washing plant – a) Red brightener. b) Blue brightener. Mainly optical brightener is used to improve the brightness of garments.

24. Resin:

Resin is high-efficiency textile resin based on etherified-dimethylolglyoxalin mono urine urea. Resin is used for the creation of semi-permanent creases in denim and other cellulose fabrics. It is used also cotton and polyester fabric. The fabric retains a soft handle after washing.

25. Sodium Metabisulphite:

Sodium metabisulphite is used in the washing plant to neutralize the garment from potassium permanganate.
