They prevent the transition of colors between washed items and catch released dirt particles.
During each wash in water, in addition to dirt particles, washed dyes also collect, which in turn can dye other fabrics. Colour- and dirt-catching wipes trap dyes and dirt particles from the water and prevent them from collecting on washed fabrics. Washed fabrics do not lose their colors, and white remains snow-white.
The package contains 50 pcs.
