1.1 Introduction
Garments industry is the fastest growing together with competitive sector inwards Bangladesh. It is likewise challenging equally well. People's Republic of Bangladesh earns 76 per centum of full unusual currency from this sector past times exporting RMG. Washing is a novel together with of import technique inwards garments trade. That is why the report of washing technology does deserve good practical practice. So our academy provides us a projection piece of employment on garments washing. We bring completed our projection piece of employment inwards HAMS WASHING & DYEING LTD together with around business office inwards our lab.

1.2 Objectives:

The principal object of garments washing is to know the procedure of washing, such as, Stone, Enzyme, Acid together with Bleach wash.
Analyze the resultant of dissimilar washing, together with compare which washing is to a greater extent than preferable for garments washing.
To analyze the piece of employment of dissimilar chemic on garments washing together with compare the resultant of chemic on garments.
To do novel fashion similar dissimilar types of fading resultant inwards garments.
To prepare soft feeling resultant on the garments past times using softener together with do novel outlook.

2.1 Garments washing:
It is a technology past times which outlook, comfort might & fashion of garments is changed or modified & given one-time garment effect. Various types of chemicals & materials may live needed to do the specific wash.

2.2 Types of garment washing:

Normal wash
Bleach wash
Stone wash
Acid wash
Enzyme wash
Caustic wash
Super white wash
Wash & over dyeing(dirty washing)

2.2.1 Normal wash:
Normal launder is used to take size material, adhering dyes, together with whatever dart or oil topographic point of the garments. It is likewise used to prepare the launder expect of garments together with to improve the soft feeling of garments. Detergent is used inwards normal wash. We instruct soft feeling resultant through normal wash.

2.2.2 Bleach wash:
Fading resultant is produced inwards the garments past times partial bleaching action. Color garments are unremarkably dyed amongst straight or reactive dyes. Due to the piece of employment of bleaching agent this launder is called bleach wash. Soda ash, antistant, pulverization enzyme, liquid enzyme together with H2O2 is used inwards bleach wash. Through bleach launder fading resultant tin live done on garments.

2.2.3 Stone wash:
Stone launder is done on garments made from denim together with jeans fabric. Fading resultant is produced inwards the garments inwards irregular pattern. Garments leave of absence comfortable during piece of employment afterwards stone wash. Soda ash, antistant, pulverization enzyme, liquid enzyme together with pneumic stone are used here. Through stone launder nosotros tin instruct soft feeling resultant amongst fading of garments.

2.2.4Acid wash:
Garments made from heavy jeans & denim fabrics are washed past times acid launder technique. Pneumic stone is used for washing. Soda ash, antistant, liquid enzyme, pulverization enzyme acetic acid together with Pneumic stone are used inwards acid wash. Irregular spoty resultant tin live produced inwards the garments through acid wash. Pneumic stones are perforated stones produced past times volcanic explosion. At start it is soft, but becomes cold, it seems to similar the stones amongst stone oil surface. This type of stones floats on water.

The pneumic stones to live used during acid launder should live pre treated inwards the next chemic solution.

Recipe:

Water : 100 L
Potassium permanganate : 1.2 kg
Phosphoric acid : 300 ml

The solution was stirred inwards a stainless steel bowl.

The pneumic stones were soak inwards the stock solution for 2-3 2nd .Then the stones were dried inwards opened upwards air for threescore to ninety min.

2.2.5 Enzyme wash:
Indigo dyed warp yarn are sized amongst Starch together amongst soluble PVA to take this size materials enzyme launder is used. In club to plow over the textile a soft resultant & to plow over the denim a stone launder look, amongst ameliorate prissy bluish together with white contrast on the surface. Soda ash, antistant, pulverization enzyme, liquid enzyme are used during enzyme wash.

2.2.6 Caustic wash:
High density alkali medium is used inwards caustic launder which take the protruding fiber from the textile surface together with likewise fade the color of the fabric. “Caustic” is a chemic amongst corrosive nature, or potent cleaning might peculiarly for oil spot. In this procedure all the dirt fine particles of cotton fiber seeds & all unusual materials are cleaned up.

2.2.7 Garments washes & garments over dyeing:
This type of launder is done on the garments afterwards acid launder or stone wash. Normally, straight or reactive dyes are used for over dyeing. If straight dyes are used for over dyeing, at the terminate of dyeing color fixing agent is needed to ready the straight dyes. If reactive dyes are used for over dyeing, together with then staining of other garments during cleaning tin live avoided.

2.2.8 Super white wash:
During stone launder & bleach launder OBA is used inwards the concluding rinsing to brand the white threads inwards the textile whiter to do stronger contrast betwixt bluish & white on the surface of the fabric.

2.3 Machineries used inwards garments washing industry:
