Key production numbers
Garment washing is a post-production process that changes the surface, hand and colour of the fabric. Common directions include stone wash, enzyme wash, acid wash, garment dye and aged finishes. Wash options are evaluated during sampling once the denim or fabric direction is agreed.
For custom jeans programs, starting quantities can be discussed from 50 units per style, subject to denim, wash and hardware review. Sample development is typically targeted within 15 days after the specification is approved.
Why garment washing matters
Washing is a design tool as much as a finish. It softens fabric, creates depth and character, removes shrinkage and gives the garment a lived-in or premium feel. The same raw fabric can look completely different after a stone wash versus a garment dye.
Washing also stabilises the fabric: most shrinkage occurs in the first wash, so pre-washed garments are more predictable for the buyer and the wearer.
Stone wash
Stone wash uses pumice stones in the washing drum to abrade the fabric surface, softening the hand and creating lighter, irregular fade patterns around seams, hems and pockets. It is a classic denim finish for casual and vintage looks.
Stone wash is heavier on the fabric and equipment; confirm the abrasion level against a reference sample before bulk.
Enzyme wash
Enzyme wash uses cellulase enzymes to break down surface fibres, producing a smooth, soft hand with subtle lightening and minimal mechanical wear. It is gentler than stone wash and works well on knitwear and lighter denim.
Enzyme treatment can be combined with stone for a softer version of the stone-wash look.
Acid wash
Acid wash — also called marble wash — uses chlorine-soaked stones to create irregular light patches across the fabric. The effect is bold and high-contrast, popular in streetwear and retro styles.
Because the effect is inherently irregular, agree acceptable variance before bulk production.
Garment dye
Garment dye colours the finished garment rather than the raw fabric. It produces deeper colour penetration on seams, pocket linings and labels, with a more saturated, lived-in tone and a softer hand.
Garment dyeing affects sizing and shrinkage more than fabric dyeing; test wash and measure the dyed sample before confirming the size chart.
Planning washes in production
Confirm wash direction, effect reference and acceptable variance during sampling. Agree which measurements are checked after washing and what tolerances apply, since washed garments can shift from the pre-wash chart.
Wash effects vary slightly between batches — set expectations with your buyers and keep a sealed wash reference for each production run.
Frequently asked questions
Which wash is best for raw denim? It depends on the look: stone for classic fade, enzyme for a smooth hand, acid for high-contrast streetwear, garment dye for saturated colour. Which wash keeps the garment softest? Enzyme and garment-dye finishes generally produce the softest hand. Can washes be combined? Yes — stone + enzyme or enzyme + dye combinations are common. Do washes affect sizing? Yes; confirm post-wash measurements and tolerances during sampling.
