Enzyme: The action of enzyme during enzyme wash it hydrolysis the cellulose. At first it attacks the having projecting fibres and hydrolyzed them. Then it attacks the yarn portion inside fabric and party hydrolyzed the yarn portion. As a result colour comes out from the yarn portion and fadded affect is produced.

Detergent: Chemical character is fatty alcohol polyglycol either in an aqueous, glycolic solution. Detergent is widely applicable in the continuous and discontinuous pretreatment o all types o fibre and their blends. To remove impurities, mineral oil, contamination and sizes from the garments. Scouring of oods for dyein and printin fully white and colour articles

Acetic Acid (CH₃ CooH): Acetic acid is used to neutralize the garments from alkaline condition and to control the P^H value in wash bath.

Antistain: Antistain is used to prevent the staining on weft yarn of the denim (White yarn). White pockets of garment, levels, contacted fabrics of garment and increased to brightness of fabrics. It is also acts as anticreasing agent.

Bleaching powder: Bleaching powder is an oxidizing agent. It is used in washing plant for colour out from the denim garments. We can achienc different shade of colour on garment i.e. Dark, Medium, Light Shade.

Sodium Hyposulphite: Sodium Hyposulphite is used to neutralize the garments from chlorine bleach.

Caustic Soda: Caustic Created the role in bleach technique with out colour change the garment has a good cleaning power, it is work as fadding affect / old looking affect come rapidly on garments.

Soda ash: Soda ash creates alkaline medium for the breakdown action on bleach bath. It has a cleaning power and help colour fadding affect of garment. It is used also for colour fixing in the dye bath.

Sodium Bicarbonate: Sodium bicarbonate is used in washing plant in the bleach bath with bleaching powder for denim light shade because easily colour out with in short time. As a result production increases and costing is low.

Potassium permanganate: Potassium permanganate is used in acid wash with punic stone for colour out from the garments. It is used also spray chamber by nozzle for colour out (whitish affect) from the garments.

Flax Softener (cationic, non ionic): Softener is used to make the garments treated textiles a surface feel that is both sickly and soft and also provides excellent lubricating properties.

Micro emulsion Silicon: Amino silicon is a textile finishin aent cousistin mainly of an amino modified Silicon. When applied on fabrics, it gives durable Sofness, lubricity, tear resistance ad fabric to be cut and sewn more easily allows and improving wear and easy care properties.

Sodium Chloride (Salt): It helps to exhaust dye in to the fibre.

Buffer: Buffer is used in washing plant for P^H control of enzyme bath, Softener bath, desizing bath.

Hydrogen per oxide: Hydrogen peroxide create the prime sole in bleach wash technique. In alkaline medium, hydrogen peroxide breaks up and give some perhydroxhyl ion. Which discolour the colouring materials and as a result fadding affect is developed. Hydrogen peroxide is used in scouring bleaching bath for white / ready for dyeing o gray fabric garments. It is used also neutralized the garment from alkaline condition.

Stabilizer: Hydrogen peroxide is work a good condition a temperature above 90^oC, when temperature raise to 90^oC then break the hydrogen peroxide. Stabilizer is used to protect break the hydrogen peroxide and peroxide works in bath smoothly.

Fixing Agent: Fixing agent is used for unfixed dye to fixed o fabrics, when fabric colour will be proper fixing them colour fastness & subbing fastness will b increased.

Catanizer: Catanizer is used is pigment exhaust method processing. Pigment is colour not dyestuff. Pigment colour have no affinity to fabric when catanizer is used in fabric then increase the affinity between pigment colour & fabrics.

Optical brightness: Two types of optical brightner are used in the washing plant- (a) Red bightner (b) Blue brihtner. Mainly optical brightner is used for improve the brightness of garments.

Resin: Resin is high efficiency textile resin based on etherified dimethylol glyoxal monoureine 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. Fabric retains soft handle after washing.

Sodium Metabisulphite: Sodium metabisulphite is used in the washing plant to neutralized the garment from potassium permanganate.

Desizing Agent: Desizing agent is used to remove mainly Starches, CMC, Waxes, Fats pectin’s, Minerals & Unfixed indigo dye from denim, twills, poplin & canvas fabrics.

Colour Shade Variation & Solution: When fabrics come in to garment factory against any order from abroad / local fabric dyeing factory, its found different colour shade roll in the same colour i.e. Slide Light, Slide Dark, Slide Tone different for this reason garment factory to control Shade variation work as follows:

• 8″ x 8″ Size fabric cut from every roll.
• Marking roll number by permanent marking pen a back side of cutpes.
• Every cutpes joint each other and make a blanket.
• Then it wash into standard approval shade.
• Garment factory now segregate same colour tone in one bundle and shade grading A, B, C, D.
• First A shade roll cutting by pattern then B, C, D shade separately.
• After garment making shade level attached on body.
• Then go to washing plant for standard washing.
• Washing plant shade level wish washing in respective wash.
• After wash it any bid shade variation found then again rewash to match with buyer approval standard.
• Final quality checking garment go to finishing section for thread cutting, button attached, iron & poly etc.
