Problems & Solutions
Excessive Wool Fabric Shrinkage: Root-Cause Guide
Why can wool fabric shrink after approval?
01 · Define the buyer decision
What must be decided before you compare suppliers
The phrase wool fabric shrinkage problem 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.
Felting versus relaxation
Write the intended result in the brief and ask how the proposed construction, blend or process will reproduce it in bulk.
Wet care versus heat
Write the intended result in the brief and ask how the proposed construction, blend or process will reproduce it in bulk.
Warp and weft behaviour
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 method and result
State the method, unit, tolerance or physical reference where relevant. Record who approves it and at which sample or bulk stage.
Bulk lot test
State the method, unit, tolerance or physical reference where relevant. Record who approves it and at which sample or bulk stage.
Pressing and fusing trial
State the method, unit, tolerance or physical reference where relevant. Record who approves it and at which sample or bulk stage.
Finish-process record
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
Only home laundering is investigated
Include factory processes.
Cutting starts before relaxation
Hold and remeasure.
Bulk finish differs from sample
Compare recipes.

Frequently asked questions
Quick answers buyers can reuse
01Why can wool fabric shrink after approval?+
Shrinkage may come from fibre felting, insufficient dimensional setting, wet care, steam, fusing or delayed relaxation. Reproduce the actual garment process, measure both directions and compare development with bulk finishing records.
02What should an RFQ include for wool fabric shrinkage problem?+
Include Approved method and result, Bulk lot test, Pressing and fusing trial, Finish-process record. State the test methods, tolerance, quantity by colour and intended garment so quotations are comparable.
03What should buyers check before bulk approval?+
Only home laundering is investigated: Include factory processes. Cutting starts before relaxation: Hold and remeasure. Bulk finish differs from sample: Compare recipes.
