Wet Process

Enzyme Wash

Enzyme washing is a laundering process that uses enzymes to clean clothing or to finish fabric, especially in the case of jeans and other garments with a worn-in look. Various enzymatic cleaners are available from stores that specialize in laundry supplies, and they can also be special ordered. For regular cleaning, enzymes carry many economic and environmental benefits. On an industrial scale, it has replaced laborious laundering techniques such as stonewashing, saving money and environmental impact for companies.

The enzymes used in this technique are proteins produced by living organisms. All organisms produce a wide range of these proteins to accomplish necessary biological tasks. Some can also be replicated in the lab, or engineered to perform in a particular way. One of the reasons that enzyme washing is so ecologically friendly is the natural origins of enzymes, which biodegrade rather than lingering in the water supply. These products are also much more potent than other laundry products, requiring people to use far less, in terms of volume.

Different types of enzymes are suitable for different stains. In all cases, the washing process breaks the stain down into smaller molecules, which can be removed with water or conventional soap. Amylases will remove starch-based laundry stains, while proteases break down protein chains, making them suitable for protein stains. Lipases work very well on grease and oil, and cellulases are excellent general cleaners. The washing process also yields a softer, more supple garment.

Acid Wash

This is the oldest of fashion washes in denim after stone wash. The name acid wash is in reference to the acids used for this wash in old recipes. In new methods it is done with oxidation. Use of bleach/oxidative is very safe and economical in comparison to acids. Different chemicals are used and among them potassium permanganate (KMnO4) and sodium hypochlorite are mainly used.

Acid wash is typically done by soaking pumic stone in hypochlorite. Some time KMnO4 is used in replace of bleach. Selection of oxidant is very important and mainly depends on the type of fabric. When it is done with pumice stone the washer and garment should not contain any water. Dry garment is much suitable for this process then a damp one. Pumic stones are soaked in bleach and left it to open for little time so they get only damp rather than wet. Then they are processed in machine with garments. The extent of effect is controlled with process time, concentration of oxidant solution and quantitative ratio of garment to stone.

Rinse Wash

In this type of washing, only softening is used. Garments are washed with softener to soften the fabric and this process can be done with clear softener where it only achieves a softer touch. Rinsing can be divided into oxygen bleach and chlorine bleach. Oxygen bleach is the use of hydrogen peroxide in a certain temperature, PH value and the oxidation to destroy the structure of dyes to achieve the fade, the purpose of whitening, general drift slightly reddish cloth. Chlorine bleach is the use of sodium hypochlorite oxidation to destroy the structure of dyes to achieve the purpose of bleaching. The fading effects of chlorine bleach rough, used for indigo blue denim rinse.

Silicone Wash

The process of softening done by the use of macro or micro emulsion softeners known as silicone oil. Silicon washes generally done on all type of fabrics i.e. Twill, Denim,Canvas, Knit,Corduroy.
Silicon wash is required for the following reasons: 1. It gives durable softness, elastic handle.
2. It helps to anti-pilling affects, dimensional stability, and tear resistance.
3. It helps to fabrics to be cut and sewn more easily allows and improving wears and easy careproperties.

Potassium Wash

It is done by tumbling the garments with pumice stones presoaked in a solution potassium permanganate for localized bleaching resulting in a non uniform sharp blue/white contrast. In this wash the color contrast of the denim fabric can be enhanced by optical brightening. The advantage of this process is that it saves water as addition of water is not required.

Bleach Wash

In the process, a strong oxidative bleaching agent like sodium hypochlorite or KMnO4 is added during the washing with or without stone addition. Discoloration produced is usually more apparent depending on strength on the bleach liquor quality, temperature and treatment time. It is preferable to have strong bleach with short treatment time.

Dirty Wash

After stone-washing the jeans or denim jackets, they will be dyed with special chemicals, thus creating a look in which the jeans will appear to be dirty.

Resin Wash

Usually a resin wash is when the denim is treated for a wash with resin, which allows the areas that do not get as much abuse to retain a darker color after washing. It's basically an easy way to get a high contrast fade from cheaper denim.

Dry Process

Hand Sand

Hand sand is step which is generally being done in rigid form of garments to get distress look. Locations can be front thigh & back seat or its can be overall/global application as per Standard.Emery paper is being used to scrape the garments in particular placement & design. Purpose of doing this process is make used worn out look to the garments.

Sand Blast

Sandblasting is defined as the erosive/abrasive process applied to denim by air compressors blowing out sand under pressure in order to bleach and to batter the denim.
Sandblasting achieves a very precise bleached look. Applying sandblasting, particular parts of denim can be treated while others are left out. This way special patterns and effects as demanded by designers can be achieved.Hand sanding must be started from intense part & feathering out on less intense part gradually.

Whiskers

Whiskers/Mustaches/Chevrons are nothing but the worn out lines or impression generated by natural wearing on hip & thigh area. There are many designs & pattern available. This is being done manually with help of sharp edge Emery paper rolled on fine wood stick or pasted on plastic material. Before starting execution placements & pattern must be marked on garments, this will help operator to execute the pattern right to match the aesthetics of garment.

Hot spots are heavy/intense area on thigh or knee which is made purposely to create used look & on knee area if any whiskers line are there, called knee star. All above operations are carried out in width direction hence its appears intense than hand sand with less strokes, because hand sand is carried out in length direction.

Grinding and Tacking

Grindin is being done on pocket edges and bottom hems edges by running against abrasion surface or stone to achieve worn out effect. Many different make of machines and pen grinding tools are available in the market which runs with pneumatic system.

Tacking is a process which is being done by swift tag machine with the help of plastic or nylon tag pins in rigid form of garment to get very heavy contrast ( rigid & washed ) on waistband, bottom hems, back pocket & front pocket corners, etc. After completing wash cycle, it must be removed from garment before making softening.

Destruction

"Destruction" is an art which make denim look unique and used. To make destruction pen type of stone tools being used in mid of wash process to apply on desired area. It can also be achieved by cutting it thru knife the warp yarns and keep the weft yarn as is to show white thread. Holes also can be made by cutting weft and warp yarns. These are all manual processes and every garment will look unique and different than others.

3D Whiskers

There are several different techniques to make the jeans or denim jackets look old, worn and /or used. Most of these techniques involve actual sandblasting or abrading by some kind of power tool. Whiskers, which normally appear around the hip to crotch area of the pant, are usually made by using a grinder. Another popular way to make jeans appear damaged is to cut the edges at bottom, (back-) pockets, fly and knee area before the (stone) washing.

Bleach Spots

Bleach spotting is a manual process to give denim a unique and vintage look. Denims are first cut or damaged intentionally and then repaired by hand or machine to look natural. Diluted bleach can then be used to spot the desired area followed by neutralization in wet process.
