What is color bleeding?#
Color bleeding happens when dye comes off a fabric in washing and transfers to other areas: white or light panels in the same garment, labels, trims, or other garments in the wash. It is a consumer-facing problem, often found only after the garment is sold, and a common reason for complaints and returns.
It is tested as the staining part of color fastness to washing.
What it looks like#
- Dark color spreading into white collars, cuffs, stripes or piping.
- Staining on care labels and inside seams.
- Colored wash water in the first washes.
- Staining on other items washed with the garment.
- Low staining grades on the multifiber strip in test reports.
Where it occurs#
- Garments combining dark and light colors: colorblock designs, white trims on dark bodies, stripes.
- Deep shades: red, navy, black, dark green.
- Printed garments with poorly cured pigment or reactive prints.
- Garment-dyed and washed products.
Likely causes#
Most bleeding is caused by dye that is not fixed to the fiber and has not been removed by washing-off after dyeing. Some dye classes also have limited fastness at higher wash temperatures. The risk grows when a garment combines a dark part with a white or light part that can be stained.
Machine-related causes#
- Insufficient soaping and rinsing after reactive dyeing, leaving unfixed dye.
- Fixation conditions: temperature, alkali and time outside the recipe.
- Print curing too short or too cool for pigment prints.
Material-related causes#
- Dye class not suited to the fiber or the required wash fastness.
- Deep shades with high dye loads.
- Trims and labels dyed with low-fastness dyes.
Operator and process-related causes#
- Garment washing at a higher temperature or longer time than specified.
- Shortened processes to save time.
Method-related causes#
- No wash test of the combined garment, only of each fabric on its own.
- Care label instructions that allow a higher temperature than the fabric can take.
How to confirm the cause#
- Test color fastness to washing of the dark fabric to the buyer's method, and check staining grades.
- Wash a whole garment under the care label conditions and look for staining on light parts.
- Test trims and prints separately.
- Review dyeing and washing-off records for the lot.
- Compare with a lot that passed.
Immediate containment#
- Hold the fabric lot and garments already produced.
- Wash-test garments from bulk.
- Stop production of colorblock or contrast garments using the lot.
Corrective action#
| Cause | Corrective action |
|---|---|
| Unfixed dye | Rewash (soaping) the fabric until wash-off water is clear, then retest |
| Wrong dye class | Change dye selection for future lots |
| Poor print curing | Re-cure where possible; correct curing settings |
| Trims bleeding | Replace trims with tested ones |
| Garment wash too hot | Correct wash recipe |
| Care label | Align care instructions with test results |
Preventive action#
- Wash fastness tests of each color at development and in bulk.
- Garment wash tests for any design combining dark and light parts.
- Trim testing for color fastness.
- Dyehouse process control for washing-off.
- Care labels based on test evidence.
Inspection notes#
- Bleeding is found by testing, not by visual inspection of new garments.
- Keep test reports linked to fabric lots and styles.
- A failed staining grade or visible staining after a garment wash is normally a reason to hold the lot.
Example investigation#
A navy polo with white tipping on the collar shows blue staining on the tipping after a home wash. The navy body fabric passed its own wash test. The collar was knitted with navy and white yarns, and the navy yarn came from a different dyehouse. Testing the collar alone gives poor staining on cotton. The collar yarn dyehouse had shortened soaping. Future collar yarn lots were tested before knitting, and a whole-garment wash test was added for contrast styles.
Bleeding compared with other color problems#
| Problem | What happens |
|---|---|
| Bleeding | Dye leaves the fabric in washing and stains other areas or garments |
| Poor rubbing fastness | Color transfers by friction, dry or wet |
| Fading | The fabric itself loses color, with or without staining |
| Shade variation | Parts differ in color from the start |
Factory checklist#
- Each color tested for wash fastness
- Combined garment wash tested for contrast designs
- Trims and prints tested
- Dyeing and washing-off records reviewed for problem lots
- Care label matches test conditions
