Cellulase enzymes.
Cellulase enzymes were introduced in the 80s to assist denim washing to get a faded and abraded look different from what is traditionally provided by pumice stones. Cellulase enzyme fastens the abrasion by a process known as ‘bio stone washing’.

Which enzyme is used for denim washing?
Cellulases
Cellulases are the most successful enzymes used in the textile industry (Kuhad et al., 2011). Cellulases are used in the biostoning of denim garments (jeans) and biopolishing of cotton and other cellulosic fabrics (Bera et al., 2015).
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.
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.
How are stonewash jeans made?
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 stone enzyme wash?
Stone wash means washing garments with special stones so that garments achieve a very strong washed effect. To get a faded look on the garment surface, white stones are used with enzymes during washing. During washing, the fabric comes in contact with stones and the color fades by the rubbing action.
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.
Why do we use enzyme washing in denim?
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 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 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 is neutral cellulase enzyme?
Neutral Cellulase enzyme is a derived from modified strain of Humicola insolens by submerged fermentation. It improves texture and appearance of fabric or garment, especially woven, knit & denim. APPLICATION: Neutral Cellulase enzyme is used for biopolishing of cellulosic fibers under neutral conditions.
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.
How does stone wash work?
The garments are placed in a large horizontal industrial clothes washer that is also filled with large stones. As the wash cylinder rotates, the cloth fibers are repeatedly pounded and beaten as the tumbling stones ride up the paddles inside the drum and fall back down onto the fabric.
How are light wash jeans made?
Chlorine and water is added to a larger drum, after which the denim jeans are placed inside, either with or without pumice stones. As the jeans rotate in the solution of bleach and water, it turns the denim materials into a lighter color; thus, creating the characteristic features of acid wash jeans.
What are the enzymes in laundry detergent?
Most biological laundry detergents contain lipase and protease enzymes, both of which are found in the body. Lipases break down fats and oils, while proteases work to break down protein chains. Their ability to break down these compounds makes them excellent for stain removal.
Why we do enzyme wash in fabric?
In all cases, the enzyme washing process breaks the stain down into smaller molecules which can then be removed. Enzyme washing also produces a softer, more supple garment. For delicate fabrics, enzyme washing can be an excellent way to get clothing fresh and clean without harming the garment.
What is enzyme in textile?
The commonly used enzymes in textile processes are amylases, catalase and laccase. These are used to remove the starch and scale down the effectiveness of hydrogen peroxide, lignin and bleaching textiles. Enzymes are safely used in the textile processes like de-sizing, scouring, bleaching, dyeing and finishing.
What is heavily washed jeans?
Washed denim, on the other hand, is denim that’s washed before it’s sold. It’s produced in the same way as raw denim, with cotton yard being dyed and then spun into denim. The fundamental difference is that washed denim is literally washed in water before it’s sold.
Is Borax an enzyme cleaner?
While vinegar, borax powder, and hydrogen peroxide are impressive cleaning agents, they are unfortunately not an enzyme cleaner. They do break down stains, but it’s not by using enzymes like protease and terpenes.
Is OxiClean an enzyme?
One of the ingredients that helps OxiClean Laundry Detergent attack stains and smells so effectively is enzymes, specifically proteolytic enzymes. They work in much the same way the live enzymes work in Bac Out.
