Acid Wash Hoodie Manufacturer: Fleece Wash Process and Specs

Acid wash hoodie manufacturer programs tumble dyed 350–500 GSM cotton fleece or French terry hoodies with oxidiser-soaked stones to create a marbled, high-contrast fade. Plan 5–8% wash shrinkage, 1–3 wash trials, 12–20 days for a washed sample and 35–50 days for bulk, with MOQ depending on style and fabric.

Acid wash hoodies are a staple of vintage-inspired streetwear: a dark fleece hoodie covered in bleached, marbled patches that look like decades of wear. The look is bold, but heavy fleece is a demanding fabric to wash. It is thick, brushed on the inside, and attached to trims such as drawcords, eyelets and sometimes zips. This guide explains how an acid wash hoodie manufacturer produces the effect, what can go wrong and how to approve a program with confidence.

What is an acid wash hoodie manufacturer?

An acid wash hoodie manufacturer is a factory that sews cotton fleece or French terry hoodies and then applies an oxidiser and stone wash to create a marbled, high-contrast fade. Most programs use 350–500 GSM cotton fabric, run 1–3 wash trials to lock contrast, and plan 5–8% wash shrinkage in the pattern. A washed sample usually takes 12–20 days, with trims, prints and strength checked after washing.

How does acid wash work on a hoodie?

Despite the name, most acid wash today does not use acid. The wash house soaks pumice or synthetic stones in an oxidiser, traditionally potassium permanganate or a chlorine-based bleach, and tumbles them with the dyed garments. Where stones hit the fabric, colour is stripped, creating patches and veins. The garments are then neutralised to stop the reaction, rinsed, softened and dried.

On a hoodie, the hood, pouch pocket, cuffs and waistband all add layers and folds. Those areas receive less stone contact, so they often come out darker. Some brands like this natural variation; others ask the wash house to adjust load size and tumble time to even it out. Agree which you prefer before sampling.

Which base fleece and dyes work best?

Use 100% cotton or a high-cotton fabric. Polyester fibres do not react to the oxidiser, so a CVC fleece gives a weaker, patchy effect. Heavier 400–500 GSM fleece withstands the abrasion better than light fleece, and French terry gives a crisper pattern because its outer face is smooth. Our comparison of garment dye specifications for fleece hoodies covers how base dyeing affects results.

The base dye decides what colour the bleached areas become. Reactive-dyed black usually strips to a grey or off-white, while some dyes strip to brown or rust. Ask for a quick strip test on fabric swatches before cutting.

How do you protect trims, prints and labels?

Trims are the most common source of complaints on washed hoodies. Plan them deliberately:

• Drawcords. Polyester cords stay in the original colour. Use cotton cords that wash with the body, or fit cords after washing.
• Eyelets and zips. Metal can discolour or rust in oxidisers. Use wash-resistant finishes, or add eyelets after washing.
• Thread. Polyester thread stays dark; cotton or core-spun thread fades closer to the body.
• Labels. Printed labels can fade and woven labels can fray. Test them on the washed sample.
• Prints and embroidery. Decoration applied before washing fades with the garment; applied after washing it stays crisp. Our guide to distressed hoodie manufacturing covers combined wash and damage effects.

What quality checks does acid wash need?

Acid wash weakens cotton, so build testing into the program:

1. Strength. Set a maximum bursting strength loss compared with unwashed fabric, often 10–20%.
2. Pinholes. Inspect folds, seam edges, cuffs and hood edges for thin spots.
3. Shrinkage. Measure the size set after washing and adjust the pattern before bulk.
4. Residual chemicals and pH. Confirm neutralisation and rinsing are complete.
5. Colourfastness. Check rubbing and washing fastness so the hoodie does not stain other clothes.
6. Shade range. Approve a sealed sample plus light and heavy limit samples.

How does acid wash affect fit and hand feel?

Washing changes more than colour. Stones and oxidisers soften the face of the fabric, so an acid wash hoodie usually feels broken-in rather than crisp. The brushed inside of fleece can lose some loft and may pill a little, which is why many brands finish the wash with a silicone or enzyme softener. Ask to feel the washed sample next to an unwashed one so you can judge how much softness you want.

Fit also moves. Length usually shrinks more than width, the hood can shorten, and rib cuffs and waistbands can lose some recovery if the wash is strong. Measure the size set after washing, including hood height and rib widths, and adjust the pattern before bulk. If you sell a matching acid wash sweatpant, wash both in the same recipe so the colour and softness match.

Acid wash vs mineral wash hoodie: which option fits?

Acid wash and mineral wash are the two most requested vintage finishes for hoodies. Compare them on the selection criteria your customers notice.

The trade-offs are impact versus consistency. Acid wash delivers a bold, unique look but varies more between garments and stresses the fabric, while mineral wash is easier to repeat across reorders and kinder to the cotton. For a different route to colour variation, see our dip-dye hoodie manufacturer guide. We also cover the tee version in our acid wash t-shirts guide.

What should you send in an acid wash hoodie brief?

Include fabric type and weight, base colour and dye type, reference photos of the pattern size and contrast, trim materials and whether they go on before or after washing, decoration and timing, finished measurements after washing with tolerances, and the tests you require.

These are typical industry estimate ranges, not quotes; confirm actual figures with your supplier for your fabric, quantity and destination.

Key takeaways

• Acid wash strips colour with oxidiser-soaked stones after the hoodie is sewn and dyed.
• Use 100% cotton fleece or French terry, ideally 400–500 GSM, for the best contrast.
• Plan drawcords, eyelets, thread and labels so they suit the washed look.
• Set limits for strength loss, shrinkage and shade before bulk.
• Choose acid wash for impact and mineral wash for repeatable basics.
