Specifications & Testing
Water-Repellent Finish on Wool Fabric
How should a water-repellent wool finish be specified?
01 · Define the buyer decision
What must be decided before you compare suppliers
The phrase water repellent wool fabric 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.
Light shower resistance
Write the intended result in the brief and ask how the proposed construction, blend or process will reproduce it in bulk.
Finish durability
Write the intended result in the brief and ask how the proposed construction, blend or process will reproduce it in bulk.
Natural handfeel retention
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.
Repellency method and rating
State the method, unit, tolerance or physical reference where relevant. Record who approves it and at which sample or bulk stage.
Care-cycle durability
State the method, unit, tolerance or physical reference where relevant. Record who approves it and at which sample or bulk stage.
Restricted-substance needs
State the method, unit, tolerance or physical reference where relevant. Record who approves it and at which sample or bulk stage.
Approved handfeel and shade
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
Water repellent is marketed as waterproof
Use accurate language.
Finish changes shade or handle
Approve after treatment.
Performance disappears after care
Specify durability cycles.
