Problems & Solutions
Wool Fabric Shade Variation Between Rolls
What should buyers do when wool-fabric rolls vary in shade?
01 · Define the buyer decision
What must be decided before you compare suppliers
The phrase wool fabric shade variation 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.
True colour difference versus nap effect
Write the intended result in the brief and ask how the proposed construction, blend or process will reproduce it in bulk.
Roll grouping
Write the intended result in the brief and ask how the proposed construction, blend or process will reproduce it in bulk.
Garment panel matching
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.
Approved standard and light sources
State the method, unit, tolerance or physical reference where relevant. Record who approves it and at which sample or bulk stage.
Roll shade map
State the method, unit, tolerance or physical reference where relevant. Record who approves it and at which sample or bulk stage.
Tolerance and grouping rules
State the method, unit, tolerance or physical reference where relevant. Record who approves it and at which sample or bulk stage.
Replacement plan
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
Quarantine and map the affected lot
Keep the reference, result and approval owner in the order file so the next stage uses the same definition of acceptable.
- 02
Reproduce the issue with the agreed method
Keep the reference, result and approval owner in the order file so the next stage uses the same definition of acceptable.
- 03
Trace material and process records
Keep the reference, result and approval owner in the order file so the next stage uses the same definition of acceptable.
- 04
Trial the correction and retest side effects
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
Opposite nap is read as shade variation
Align direction.
Mixed lots enter one garment
