Garment washing transforms the appearance, comfort, and fashion of garments through various processes. The document discusses 10 types of washes including normal wash, pigment wash, caustic wash, enzyme wash, stone wash, super white wash, bleach wash, acid wash, silicon wash, and detergent wash. Each wash is used for specific reasons such as creating fading effects, softness, shrinkage, abrasion, consistent quality, and removing impurities. Stone wash in particular mimics natural wear by tumbling garments with stones to roughen fabrics like denim.
