Enzymes are a biological solution and they can cut consumption of chemicals, water and energy for textile producers. Used for stone washing of jeans, the enzymes break off small fiber ends on the yarn surface, thereby loosening the dye so the jeans get that vintage look.

How do enzymes affect jeans?
Khan et al. 2012). Enzyme washing is a process involving the use of enzyme to produce soft, comfort, luster and fade effect on denim fabric. The surface cellulose fibers of the denim fabric are broken down by enzymes and removes during washing.
How are enzymes used in denim jeans?
Enzymes such as cellulases have been used for finishing of denim garments since the 1980s. Cellulases primarily attack the surface of the fiber, since enzymes cannot access the interior of the tightly packed cellulose chains (Cavaco-Paulo, 1998).
What does cellulase do to jeans?
Cellulase enzymes are natural proteins which are used in denim garment processing to get stone wash look on to the denim garments without using stones or by reducing the use of pumice stone.
What does amylase do to jeans?
The most widely used enzyme in textile is amylase which is usually utilized to desize fabrics by hydrolyzing starch. Lipase is also co-applied along with amylase to remove lipids from the fabric surface (Jegannathan and Nielsen, 2013).
How do you wash jeans with enzymes?
Sprayed on the jeans
Stone washing of jeans normally takes place in large, open washing machines where the enzymes are added in the water. But spraying the enzymes on the garment instead is more efficient and reduces water consumption.
What are denim enzymes?
Enzyme washing or “bio stoning” is a textile manufacturing technique in which cellulase enzymes are applied to denim. As with traditional stone washing, the intended effect is a faded appearance and softer feel.
How do they make stone washed jeans?
Simply put, stonewashing is a laundry process where garments—in this case jeans—are washed with pumice stones. The stones are added to the laundry machine, and the rough surface of the stones abrades the fabric and wears off the indigo dye. The result is a softer touch and washed-down look.
What is a rinse wash jean?
A rinse wash is exactly what it sounds like, a quick rinse of water to help remove any excess dye. Typically a process for dark wash jeans, this simple treatment helps preserve as much rich color as possible.
How do you make an enzyme wash?
In a spray bottle or other container, mix one part enzyme cleaner with 20 parts water. Shake or stir to combine. This mixture can be used to wash cars, wash floors, and for other jobs around the house that don’t require a super-powered cleaner.
What fungus is used in acid washed jeans?
Using his Russian connections, Emalfarb hired some local scientists who discovered that the fungus Myceliopthora thermophila could give jeans that stone-washed look for one-third of the price of the enzymes. That became his second successful business venture.
What is bio stone denim?
BIOSTONE. A ceramic-based stone with special abrasive surface designed for denim garments stone wash treatment.
Where can cellulase be found?
Cellulases are a complex group of enzymes which are secreted by a broad range of microorganisms including fungi, bacteria, and actinomycetes. In the natural environment, synergistic interactions among cellulolytic microorganisms play an important role in the hydrolysis of lignocellulosic polymer materials.
What stains does amylase remove?
How amylases break down starch stains. Starch molecules are formed of long chains of sugars, making them difficult for detergents to remove. That’s why stains containing starch are so stubborn. Amylase enzymes cut the starch molecules into tiny sugars that are lifted off the fabric in the wash more easily.
What does an enzyme wash do?
Enzyme washing is a laundering process which uses enzymes to soften and finish fabric; providing jeans and other garments with a worn-in look and feel. The use of enzymes comes with various benefits both economically and environmentally. Enzyme can be used for garment washing as well as fabric washing.

Do enzymes fade clothes?
The enzymes present in biological detergent can sometimes break down the proteins that construct certain fabric dyes. Many fabric dyes are derived from natural sources, meaning they can be broken down by enzymes just like other chemicals. This means that the enzymes within bio detergent can cause some colours to fade.
What is enzyme washed fabric?
You may have seen the phrase ‘Enzyme washed’ in some of our recent product listings and might be wondering what that means! Enzyme washing refers to the process where fabric is washed using an enzyme-based solution to improve the softness.
What should I do if I want to deactivate enzyme in washing bath?
The enzymes can be stopped by changing the alkalinity of the bath or its temperature when the desired color will be achieved.
What are two disadvantages of using enzymes in washing powder?
Disadvantages
- Could have allergic reaction if misuse washing powders.
- Enzymes may enter water ways through sewage system.
- Industrial enzymes can be costly to produce.
- Denature at the high temperatures needed to kill pathogens in the washing.
- Some fabrics e.g wool are digested by proteases.
What is the difference between stone wash and acid wash?
The main difference between stone wash jeans and acid wash jeans is that the former are physically distressed, whereas the latter are chemically distressed. Stone wash jeans are physically distressed with stones. Acid wash jeans, on the other hand, are chemically distressed with acid.
