Wool Fabric Lab Dip Approval Guide
How should a lab dip be reviewed and approved?
01 · Define the buyer decision
What must be decided before you compare suppliers
The phrase wool fabric lab dip 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.
Correct substrate and dye route
Write the intended result in the brief and ask how the proposed construction, blend or process will reproduce it in bulk.
Primary and secondary light source
Write the intended result in the brief and ask how the proposed construction, blend or process will reproduce it in bulk.
Visual and measured tolerance
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.
Lab-dip numbering
State the method, unit, tolerance or physical reference where relevant. Record who approves it and at which sample or bulk stage.
Light sources and metamerism check
State the method, unit, tolerance or physical reference where relevant. Record who approves it and at which sample or bulk stage.
Approval signature or record
State the method, unit, tolerance or physical reference where relevant. Record who approves it and at which sample or bulk stage.
Bulk continuity standard
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
Verify the supplier and production role
Keep the reference, result and approval owner in the order file so the next stage uses the same definition of acceptable.
- 02
Issue one structured RFQ
Keep the reference, result and approval owner in the order file so the next stage uses the same definition of acceptable.
- 03
Record samples and approvals
Keep the reference, result and approval owner in the order file so the next stage uses the same definition of acceptable.
- 04
Link payment and shipment to acceptance
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
Approval is given from a phone photo
Review controlled samples.
Wrong fibre base changes colour
Use representative material.
Metamerism appears at retail lighting
Check more than one agreed source.
