  1. Normal Wash
  2. Pigment Wash
  3. Enzyme Wash
  4. Stone Wash

Wet Washing Process

Normal Wash:  Normal Wash is a process of cleaning, removing dust, dirt, and starch from the surface of the garments by the form of a solution. It is a simple washing process.

Purpose of Normal Wash:

  1. To remove starch from the surface
  2. To remove dust and dirt from the garment’s body.
  3. To look, Shine.
  4. To make the soft hand feel.
  5. To make it able to wear after purchasing.

Steps of Normal Wash:

Desizing

Softening

Hydro extract

Dryer

QC & Delivery

Steps are described with the recipe:

Step 1: Desizing: Desizing means to remove size materials from the surface.

 Let, The batch contains 70kg twill/denim garments.

                        Detergent=0.5gm/L

Temperature= 40-60˚C

Time =5-10 min

Drop the liquor

Cold wash

Step 2: Softening: Softening is done to soften the garments for soft hand feeling.

Recipe: 

M:L        =1:8

Time =5-10 min

Temp= 20˚C  

Softener =0.6gm/L

Acitic Acid =0.5gm/ L

Drop the liqure

Unload the garments

Hydro extract: In this step, the extra water is removed by using the Hydro extractor machine.

Dryer: A dryer is used to dry the garments.

 Load the dryer

Temp= 60-70˚C

And Time =10-15 min for cold dry

QC & Delivery:   After drying, the garments are checked, and if ok, they are then sent to finishing.

Acid Wash: Acid Wash is the most common and popular washing process in the washing section. Acid washing is a process of partially bleaching with chlorine bleach. Most of the time, Pumic stone is used during acid wash. Pumice stone is a lightweight stone produced from volcanoes explosion. The pumic Stone is used as a brush. The action between garments and pumic stone surface produce a fading effect. The more action happens, the more fading effect produce and vice versa. To minimize the cost and Washing standard matching foam is used.

Purpose of Acid Wash:

  1. To make the garments old-looking.
  2. To improve softness.
  3. To achieve buyer standards.
  4. To increase rubbing fastness.

Steps of Acid Wash: The following Steps are maintained through the acid washing process.

Dry Washing Process

Whisker: Whisker is the first process in a dry wash. This is the most common popular in the dry process. An individual design is created and then transfer the design on a rubber board or pattern. After that, the pattern is placed inside the garments and scrabbed over the pattern where the design will be depicted.

Whisker can be done in three ways.

  1. By Whiskering pattern.
  2. By manual hand scrap.
  3. Using a laser machine.  

Whiskering Pattern :

1.      At the first design is selected then a white poly is placed on the garments

2.      Marking the design with a marker with a seam line

3.      Take the rubber board or pattern and replace the poly on the rubber.

4.      Create a design on a rubber board by engraving it with a cutter or knife.

5.      The pattern is created.

6.      Now it is inserted into the garments.

7.      Scrape over the engraved area and a whisker design is made.

Manual Hand scrap :

Manual Hand scrapping is used to bring whiskering pattern design on the garments. Abrasive paper or emery paper, Pattern, Chalk is used for manual hand scrapping. Abrasive paper has variation according to use.

(i)                             P-400 (very rough) 

(ii)                           p-800 (medium rough)

(iii)                          P-1000  (very less rough)

Laser Machine: Laser machine is used In whiskering or burning effect on denim garments. This process is done after washing.

Hand Scrapping:  Hand scrapping is the manual and widely used process in the dry washing section. This process is applied after whiskering process to remove the color or fade specific area. Abrasive paper, gum tape, Air dummy, Hand is used for doing this. While scrapping on garments by hand the pressure should be uniform.

Grinding:  

A grinding machine is used to destroy the edges. Grinding is the destruction of edges of the garments. It is often done on hem, pocket opening, a pocket flap of the garments. For grinding small size stones are used in the machine.

Destroy: 

Destroy is the most common and nowadays it becomes most popular in the fashion market. To do this rocess pen grinding machines with different size stones are used. By this process, white yarn or weft yarn has worn out which makes garments unique and fashionable.

3D Crinkle/Wrinkle:

Wrinkle or crinkle bears the same meanings. This is the last process of dry Wash. If a buyer requires this wash, then it is done after completing all types of dry and wet wash. For this process, all garments wash with resin and then dried by the hydro extractor. Then the special effect is depicted. Wrinkle or crinkle is done on all types of fabrics like denim, twill, poplin, knit, viscose, Nylon, etc. In 100% solution contains 20% resin and 80% water for producing crinkle effect. Various supporting auxiliaries are used for better penetration of the solution. This solution uses because it prevents the transformation to a normal position and that causes wrinkles or creases.

These are the Different Types of Garments Washing Techniques used for the washing process.
