Описание: Potassium permanganate is sprayed in specific parts of the garment to fade color and bring a bright effect on the hand scraped area. It is often done on Denim, Twill, poplin, corduroy fabrics. It is done after the first wash. Liquid potassium permanganate color is pink but after applied to garment turns to muddy brown or grey on drying. Sometimes acetic acid or phosphoric acid is mixed to increase its intensity. It is always followed by the neutralization by Na-meta bysulphate or other neutralizing agents. The concentration of potassium permanganate will control the extent of brightness or effect.
