Problems & Solutions
Uneven Nap on Wool Fabric
How can an uneven raised surface be corrected or prevented?
01 · Define the buyer decision
What must be decided before you compare suppliers
The phrase uneven wool fabric nap 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.
Hair height
Write the intended result in the brief and ask how the proposed construction, blend or process will reproduce it in bulk.
Edge-to-centre uniformity
Write the intended result in the brief and ask how the proposed construction, blend or process will reproduce it in bulk.
Direction and shade effect
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 nap reference
State the method, unit, tolerance or physical reference where relevant. Record who approves it and at which sample or bulk stage.
Full-width inspection
State the method, unit, tolerance or physical reference where relevant. Record who approves it and at which sample or bulk stage.
Raising and shearing records
State the method, unit, tolerance or physical reference where relevant. Record who approves it and at which sample or bulk stage.
Pilling and strength after correction
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
Extra raising damages weak areas
Protect base performance.
Mixed brush directions look patchy
Standardize review.
Only centre cuttings are approved
Check edges.
