Dry and Wet Rubbing Fastness for Wool Fabric
Why should buyers test both dry and wet rubbing fastness?
01 · Define the buyer decision
What must be decided before you compare suppliers
The phrase wool fabric rubbing fastness can describe several constructions, finish levels or commercial assumptions. Use the following three gates to keep samples and quotations tied to the same end use.
Dark shade transfer
Write the intended result in the brief and ask how the proposed construction, blend or process will reproduce it in bulk.
Raised surface contact
Write the intended result in the brief and ask how the proposed construction, blend or process will reproduce it in bulk.
Pale lining or accessories
Write the intended result in the brief and ask how the proposed construction, blend or process will reproduce it in bulk.
02 · Make the request comparable
RFQ and specification checklist
Put each point in the written enquiry. Ask whether a quoted figure is a nominal target, a guaranteed range or a result from the actual production-representative sample.
Named rubbing method
State the method, unit, tolerance or physical reference where relevant. Record who approves it and at which sample or bulk stage.
Dry and wet grades
State the method, unit, tolerance or physical reference where relevant. Record who approves it and at which sample or bulk stage.
Face and reverse testing
State the method, unit, tolerance or physical reference where relevant. Record who approves it and at which sample or bulk stage.
Bulk shade frequency
State the method, unit, tolerance or physical reference where relevant. Record who approves it and at which sample or bulk stage.
Include the garment, selling market, care route, order quantity by colour, delivery location and target schedule. A technically precise fabric can still be wrong for the commercial program.
03 · Control the approval path
A four-stage working method
- 01
Name the test and conditioning method
Keep the reference, result and approval owner in the order file so the next stage uses the same definition of acceptable.
- 02
Set target and tolerance by end use
Keep the reference, result and approval owner in the order file so the next stage uses the same definition of acceptable.
- 03
Approve a representative development sample
Keep the reference, result and approval owner in the order file so the next stage uses the same definition of acceptable.
- 04
Verify production-finished bulk
Keep the reference, result and approval owner in the order file so the next stage uses the same definition of acceptable.
04 · Prevent predictable failure
Common risks and practical corrections
Only the face is tested
Include any visible or contacting reverse.
Loose surface fibre contaminates the crock cloth
Interpret fibre and dye transfer separately.
A pale trim is added late
Test real material combinations.

Include Named rubbing method, Dry and wet grades, Face and reverse testing, Bulk shade frequency. State the test methods, tolerance, quantity by colour and intended garment so quotations are comparable.
03What should buyers check before bulk approval?+
Only the face is tested: Include any visible or contacting reverse. Loose surface fibre contaminates the crock cloth: Interpret fibre and dye transfer separately. A pale trim is added late: Test real material combinations.
