There are several fabric treatments, and each gives the denim fabric a unique look and feel.
A process that physically removes color, adds contrast and causes abrasion. A 20-meter roll of fabric or (20 to 50 stitched garments) is put into a 100 kg washing machine along with pumice stones. The fabric rotated along with the stone for a cycle period. Then the denim fabric rinsed and tumble dried. Using pumice stones are the real method but nowadays other methods are followed like enzymes, ceramic balls and sands are used.
Sand or other abrasive substances are used in the wash bath to soften the denim and give it a faded appearance.
Acid Wash (also known as Marble wash, Frosted wash, Whitewash, Ice wash, Moon wash or Snow wash) and this finish give indigo jeans sharp contrasts. The process is achieved by soaking pumice stones in chlorine and then tumbling them with dry or slightly damp garments.
Actually, the term "acid wash" is a misnomer since acids alone are never used for this process.
A more efficient and environmentally friendly way to cause fading. Cellulosic enzymes are used to “eat” away at the indigo fibers. Denim treated with an enzyme wash is stronger than those subjected to other washing techniques that experience the higher level of abuse.
A laundry process (performed before washing) in which sewn garments are shot with sand in order to abrade them and cause a worn and discolored appearance. Useful for removing color from specific areas. This process is being banned as it is unhealthy for the operator.
River wash gives a vintage, the worn hand feel denim by the combination of pumice stones and cellulose enzymes. In the first cycle, the fabric and stones are loaded with the washer. In the second stage, the stone combines with the enzyme and tumbles until a natural look appears.
Manual treatment with sandpaper to create worn-in creases at the front thigh, crotch, and back and front knee which gives the appearance of “use marks”.
Denim manufacturers apply a sulfur dye before the indigo dye, which is known as sulfur-bottom dyeing, to create a grey or yellow vintage-look cast in the fabric. Colour can also be applied to the fabric after the indigo dye. This process of over-dying can change the main cast or it can be applied to specific areas to create ‘dirty denim’.
Dirty denim can also be made by using brown instead of a white weft.
