Nowadays denim wash is popular for both dry and wet washing processes. Consistent with the style and appearance, it includes new washing processes and technology like chemical and mechanical washing techniques. Denim washing is used to obtain colour fading effects and helps in giving a vintage look to the fabric. The vintage effect makes denim wear a permanent trend, especially the jeans, and the role of accurate denim wash is paramount in keeping denim in the heart of fashion.

Read on and we discuss in detail the types of denim washing.

  • Chemical Washing Techniques

-Acid Wash

-Bleach Wash

-Enzyme Wash

-Ozone Fading


  • Mechanical Washing Techniques 

-Stone Wash 

-Rinse Wash

-Water Jet Fading



-Laser Treatment 

Most used techniques for chemical washing are acid, bleach, and enzyme wash:

Denim Bleach Wash:

Discoloration produced is typically more apparent counting on strength of the solution quantity, temperature, and treatment time. It is preferable to have strong bleach with a short treatment time. Care should be taken for the bleached products so that they ought to be adequately anchored or washed with peroxide to attenuate yellowing. The main concern for using bleaching is that the chemicals used during washing can cause health problems to workers, so the industry has started opting out of using this method. 

Denim Enzyme Wash:

An enzyme may be a living biochemical substance and it works as a catalyst within the washing process. Initially, it involves step enzyme hydrolysis of the cellulose and taking away the projecting fibers from yarn, therefore giving the faded effects. For getting proper fading effects on garments, enzyme wash may be the most essential wash within the apparel industry. 

Denim Acid Wash:

Pumice stones are mostly used together with various types of acids during garment wash. By the action of pumice stones, the uneven fading effect is developed on heavy denim garments. Pumice stones’ abrasive structure creates a brushing effect on the surface of denim fabric. With more brushing action a more discolored or fading effect is developed and, by contrast, the areas where less brushing action takes place less fading effect is developed. 

Most used techniques for mechanical washing are:

Denim Micro Sanding:

In this fabric washing technique, a set of cylindrical rolls during a horizontal arrangement, either wrapped with an abrasive paper or chemically coated with an abrasive are washed to create a soft and suede effect.

Denim Stone Wash:

To enhance the garment wash effect and to offer garments a unique appearance and softer fabric, abrasive stones are introduced into the washing process. Natural or artificial stones are available for stone washing with perhaps the foremost widely used being the pumice stone. If natural stones are used, they slowly disintegrate, reducing the severity of the stonewash effect. The stones not only abrade the material but also gradually abrade within the rotary drum. A machine used for stone washing shouldn’t be used to dye delicate articles or else abrasion would be detrimental to the material.
