Acid Wash
Acid wash refers to a process where a denim garment has been treated with bleach-containing chlorine-soaked stone so that the color fades and the material becomes softer. For acid washing, pumice stones are used. Pumice stones create an irregular fading effect on heavy garments such as denim, thick canvas/twill, and sweaters. The pumice stone brushing action acts on the fabric surface. Acid washing can create a fading effect on the garment.
Acid Wash is a patented process. Only permission can be granted to use it. It can also be used as a type of stonewash. The garment is washed in two steps. In the first, it is washed with no water, while in the second, it is washed with water. Use potassium permanganate to soak volcanic stones. Stones absorb chemicals and are then saturated. The stones are dried in sunlight or ordinary air. The stones can now be used.
The denim garments have been prepared for washing. They are washed in warm water and tumble-dried in a spin dryer. The garments are then placed in a separate tumble dryer filled with treated stone. The garments are not washed with water. Run the tumble dryer to wash the garments. The garments can now be washed in the tumble dryer. The exposed parts of the garments can be abraded with stone. Hidden parts won’t be abraded.
The clothes are then taken out of their tumblers and transferred to another tumbler containing water for washing. After the rinse, you will see the acid wash effect. The chemicals in the treated stones can bleach exposed parts and whiten them. However, the remaining hidden parts of the stone remain untreated. To show acid wash, whitening agents are often added during rinse to whiten the blue jeans.
