Colourfastness to rubbing in activewear describes resistance to colour transferring from a textile surface when it is rubbed against another material. Buyers may also encounter the term crocking. The practical concern is different from a garment simply looking lighter after washing: the review considers colour that can stain a contacting surface. A useful specification identifies the material, test method, conditions and required result before production approval.
Think of an illustrative dark training top worn against a pale garment or carried in contact with other textiles. Colourfastness to rubbing in activewear helps the buyer investigate one potential transfer mechanism, but a laboratory result should not be stretched into a guarantee about every possible use. Our sportswear quality control approach connects agreed requirements with identifiable samples and documented decisions. These eight review points explain how to request and interpret relevant evidence.
1. Define colourfastness to rubbing in activewear separately from other properties
A colourfastness requirement should name the exposure being evaluated. Rubbing, washing, perspiration and other exposures answer different questions. Colourfastness to rubbing in activewear does not establish that a fabric meets every colour performance requirement. Keep the requested property explicit in the material specification and avoid accepting a report headed colourfastness without checking which individual tests it actually contains.
The public scope of ISO 105-X12 describes resistance of textile colour to rubbing off and staining other materials. It includes dry and wet rubbing assessments. This provides a clear starting definition rather than a universal pass threshold for every sportswear product. The applicable method and acceptance criteria should be agreed for the buyer’s intended use, material and market requirements.
2. Keep dry and wet rubbing results distinct
Colourfastness to rubbing in activewear should identify whether the result relates to a dry or wet rubbing cloth. A good result in one condition cannot be used to fill a missing result in the other. Ask the laboratory to show the requested conditions clearly and retain them in the approval record. This is particularly important when a summary email reports only one grade without its corresponding test condition.
AATCC TM8 also addresses colour transfer through rubbing using dry and wet test cloths. Its public description notes that prior treatments can affect transfer and that testing may be performed before or after such treatment. In colourfastness to rubbing in activewear, agree the relevant sample condition with the laboratory. Do not invent a household rubbing exercise and present it as a result from either recognised method.
3. Identify the exact material, shade and area tested
Colourfastness to rubbing in activewear belongs to the tested sample and reported conditions. Record the material code, colourway, dye or print reference, production lot where available and any finish. A report for a similar fabric should not automatically approve a new shade or changed finishing process. Ask whether the submitted specimen represents the material intended for the order or only an early development candidate.
For printed or colourblocked products, identify the area being assessed. A small motif, a dark background and a contrasting panel may need different sampling consideration. Discuss suitable coverage with the laboratory when an area is too small for the selected method. Keep the sample map or description with the report, so a result for one panel is not accidentally interpreted as evidence for the entire multicolour garment.
4. Read grades against the agreed requirement
Colourfastness to rubbing in activewear is only actionable when the buyer knows how the reported grade is assessed and what requirement applies. Read the report’s assessment scale, condition and conclusion. A grade is not a percentage of dye remaining in the garment. Avoid converting it into a claim such as ninety percent colour retention, which describes neither the reported rubbing result nor the stated assessment method.
Use a hypothetical approval record to see the distinction. Suppose a report lists separate dry and wet results, but the purchase specification lists only a dry requirement. The team can evaluate the dry result against that agreed limit; it still needs to resolve the missing wet requirement if wet performance is relevant to the brief. Do not invent a pass limit after seeing the result merely to make the sample acceptable.
Our guide to reading a textile laboratory test report explains how sample identity, method and decision rules support interpretation. Colourfastness to rubbing in activewear should be handled with the same traceability. If the report includes a qualification, deviation or limitation, keep it visible in the decision rather than copying only the most favourable number into the order file.
5. Include care and finished garment conditions where relevant
Colourfastness to rubbing in activewear may need evaluation in more than one agreed sample condition. Identify whether testing is required as received, after a specified care process or both. Where garment finishing or decoration changes the material, confirm which stage the sample represents. A fabric report obtained before an additional process does not automatically cover every effect that might follow that process.
Keep wash testing distinct from rubbing testing even when both appear in the same programme. The colourfastness to washing guide addresses another exposure and should not be used as a substitute. If the buyer also needs dimensional stability, seam strength, stretch recovery or pilling resistance, list those as separate requirements. A complete quality assurance plan explains which properties are covered and which remain unverified.
6. Investigate an unexpected result before changing the product
When colourfastness to rubbing in activewear falls outside an agreed requirement, first confirm the sample identity, report details and comparison basis. Ask whether the result concerns the intended shade, condition and method. This is not a reason to disregard an unfavourable finding; it is a way to ensure that corrective action addresses the actual material and issue rather than an unrelated sample or transcription error.
Ask the supplier for a documented investigation and proposed correction. Depending on the situation, the response may involve material processing, an alternative reference or a revised design proposal, but the appropriate remedy should follow evidence. Do not prescribe a universal chemical treatment from a single reported grade. Record the changed material or process and arrange the relevant retest before treating the issue as closed.
After a proposed correction, also consider whether other approved properties need review. A change intended to improve colour behaviour may affect the appearance or feel that the buyer originally accepted. Keep the review proportionate to the actual change. Defect classification, commercial disposition and technical investigation should be recorded clearly so a discussion about a sample does not silently become approval to ship nonconforming bulk goods.
7. Connect colourfastness to rubbing in activewear with bulk inspection
The inspection plan should explain how approved development evidence relates to production material. Colourfastness to rubbing in activewear cannot be controlled solely by keeping one historical report for all future orders. Identify relevant changes in supplier, shade, lot, finish or construction and decide which evidence needs renewal. The buyer and supplier should agree that scope before the order reaches shipment readiness.
During bulk inspection, check traceability between material records, garment colourways and the samples submitted for textile testing. An informal visual check may identify a concern, but it does not replace the agreed laboratory method. Keep inspection observations and test results as distinct records that inform the same release decision. If a result is pending, state that status explicitly rather than marking the requirement complete because the sample has been sent.
8. Retain a concise colourfastness to rubbing in activewear approval record
Use a compact record that someone outside the original discussion can understand. It should show what was tested, under which conditions, against which requirement and with what conclusion. Include the report reference and any unresolved action. This reduces the chance that an old result, a supplier assurance or a test request is mistaken for a completed approval.
| Record field | What to confirm |
|---|---|
| Sample | Material, shade, production reference and tested area |
| Method and condition | Agreed method, dry or wet assessment and any pretreatment |
| Requirement | Applicable acceptance criteria and assessment basis |
| Outcome | Reported result, limitations, decision and follow-up responsibility |
Colourfastness to rubbing in activewear should remain linked to the current material specification when a repeat order is placed. Confirm whether the approved reference is unchanged and whether the existing evidence still applies. Keep replacement reports and accepted corrections together with the original finding, so the production team can follow the decision trail rather than relying on a general statement that the colour issue was solved.
Frequently asked questions
Does rubbing colourfastness measure abrasion resistance? No. Colour transfer under rubbing and physical resistance to wear are different properties. Specify the required evaluation for each concern rather than treating one test as evidence for both.
Is a washing result enough? No. Washing and rubbing involve different exposures. Request the relevant rubbing assessment when it is part of the buyer’s requirements.
Who should set the passing requirement? Agree the acceptance criteria with the responsible buyer and technical team before testing, using applicable product and market requirements. The method name alone does not supply a universal commercial limit.
