Illustrative situation
A brand’s black fleece hoodie looks grey and tired after a handful of washes. The first batch looked deep and even, and the buyer wants to know what to change in the product and what is simply the nature of black cotton.
Main answer
Black fades because some dye leaves the fabric in washing, surface fibres abrade and lighten, and light and detergent add to the effect. Deep shades need a lot of dye and good wash-off during production, so the factory controls part of it, but some fading of black cotton is normal. Ask for a colour fastness to washing result and agree a minimum grade.
Why black is the hardest colour
A deep black needs a high amount of dye on the fibre, and any dye that is not firmly fixed or washed off in production can leave in the first home washes. Abrasion lifts surface fibres, which look paler because they scatter light, and brushed fleece has many of them. The result is a greyed look even when the dye in the fibre is intact.
What the factory can control
Dye selection and process. The dye class and fixation method affect how firmly colour stays. Wash-off. Thorough rinsing removes unfixed dye. Fabric finish. Excess brushing or enzyme steps increase surface fibre loss. Yarn. Better yarn sheds less. Pre-wash. A garment wash can remove loose dye before it reaches the customer.
How to test it
ISO 105-C06 specifies how to test colour fastness to domestic and commercial laundering, using a reference detergent and measuring colour change and staining, and AATCC TM61 provides accelerated laundering tests that approximate multiple washes in one test. Ask for the result on your colour and fabric, state the method, and agree the grade on the grey scale you will accept for colour change and staining.
What to tell customers
Add clear care instructions: wash inside out, in cold water, with similar colours, and avoid bleach and long tumble drying. Be honest that dark colours show wear sooner. Consider a garment-dyed or pre-washed finish if you want a lived-in look from the start. See options on hoodie manufacturer and washed hoodies.
Fact, recommendation, uncertainty
- Established fact
- ISO 105-C06 and AATCC TM61 are laundering colour fastness methods, and results are expressed as colour change and staining grades.
- Recommendation
- Request a laundering fastness result for your exact colour and fabric, agree a minimum grade and print care instructions that limit fading.
- Uncertainty
- Laboratory grades do not predict exactly how a garment will look after a customer’s own washing habits.

More perspectives from the team
Three further views on the same question, each by function. They add conditions and limits to the main answer; they are editorial notes, not customer reviews.
Sino Finetex Editorial Team Sourcing
Ask the supplier for fastness results on the same colour and fabric, and for the dyeing method used, then compare quotes on that basis. Limit: a low price for black may reflect a lighter dyeing process. Ask whether the black is piece-dyed, yarn-dyed or garment-dyed, since each ages differently.
Sino Finetex Editorial Team Product selection
If fading matters to your customer, consider a garment-dyed or washed black that is designed to age, or choose a charcoal that hides wear. Limit: lighter shades change the brand look. A slightly softer black or charcoal shows wear less than jet black.
Sino Finetex Editorial Team Quality & care
Wash a sample against a retained original and record the colour change, using the same wash settings each time. Limit: judge under the same lighting, or the comparison misleads. Keep a retained unwashed swatch for comparison.
