Denim acid washing machine is designed for denim stone washing (non-water) and sand wash (non-water). To soak the pumice stone with potassium permanganate solution then put it into an acid washing machine and rotate with denim. During this washing process, PP will oxidize the touch parts and there are some nice snow patterns on denim.

History of Acid Washing

In the early days, denim washing involved traditional methods such as stone washing and sandpaper abrasion. While these techniques achieved a worn-in look, they lacked the distinctive character that acid washing would later bring.

There are 3 major steps involved in the acid washing process. These are as:

Acid Washing Steps
Steps of Acid Washing

1. Pre-Washing Preparation

Before acid application, denim goes through a thorough pre-washing process to prepare the fabric for treatment.

2. Acid Application

Acid is applied evenly, reacting with the denim to create the desired faded effect. This step requires careful calibration to achieve consistent results.

3. Neutralization and Rinse

To ensure the garment is safe for wear, a neutralization process follows, eliminating any residual acid. A thorough rinse completes the process, leaving the denim ready for further treatment or finishing.
