Wool Fabric Shrinkage Testing Guide
How should shrinkage be tested before cutting wool fabric?
01 · Define the buyer decision
What must be decided before you compare suppliers
The phrase wool fabric shrinkage 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.
Actual care route
Write the intended result in the brief and ask how the proposed construction, blend or process will reproduce it in bulk.
Relaxation before cutting
Write the intended result in the brief and ask how the proposed construction, blend or process will reproduce it in bulk.
Pressing and fusing exposure
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.
Test method and dimensions
State the method, unit, tolerance or physical reference where relevant. Record who approves it and at which sample or bulk stage.
Warp and weft limits
State the method, unit, tolerance or physical reference where relevant. Record who approves it and at which sample or bulk stage.
Sample conditioning
State the method, unit, tolerance or physical reference where relevant. Record who approves it and at which sample or bulk stage.
Garment-process trial
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 washing shrinkage is checked
Include steam and production processes.
Rolls relax after cutting
Set relaxation time.
Average results hide one direction failure
Report warp and weft separately.

Frequently asked questions
Quick answers buyers can reuse
01How should shrinkage be tested before cutting wool fabric?+
Test the finished fabric under the intended care or relaxation process, in both warp and weft, and agree limits before production. Garment pressing, steaming and fusing can add dimensional change beyond a standard wash test.
02What should an RFQ include for wool fabric shrinkage?+
Include Test method and dimensions, Warp and weft limits, Sample conditioning, Garment-process trial. State the test methods, tolerance, quantity by colour and intended garment so quotations are comparable.
03What should buyers check before bulk approval?+
Only washing shrinkage is checked: Include steam and production processes. Rolls relax after cutting: Set relaxation time. Average results hide one direction failure: Report warp and weft separately.
