Fabric mass per area helps describe a textile but does not by itself establish weave, strength, comfort, finish or garment suitability.
Frame the decision
Evaluate weight beside fibre content, construction, finished thickness, shrinkage, color, hand feel and the test method used for the approved swatch.
The specification should use weight as one controlled material attribute within a complete construction sheet.
Build the controlled worksheet
Keep these five topic-specific inputs together so the quotation, sample and inspection teams do not work from different assumptions:
- Fiber composition: state the requirement, reference, status and approval owner.
- Weave or knit structure: state the requirement, reference, status and approval owner.
- Mass per unit area: state the requirement, reference, status and approval owner.
- Finish and shrinkage: state the requirement, reference, status and approval owner.
- Approved swatch and test method: state the requirement, reference, status and approval owner.
Evidence to request
- Approved source or drawing for fiber composition
- Order-specific record covering weave or knit structure
- Written acceptance basis for mass per unit area
- Controlled decision history for finish and shrinkage
- Release evidence connected to approved swatch and test method
Evidence must identify the relevant product, material, revision or lot. Record any limitation, substitution or item still awaiting approval.
Risks to close before approval
- Treating heavier fabric as automatically better
- Comparing unconditioned or differently finished samples
- Ignoring how construction changes after washing or finishing
Assign an owner, due date and written disposition to each unresolved risk. Do not allow an informal answer to replace a controlled revision.
Use the result in the RFQ
Attach the worksheet, quantity, destination, required date and current sample status. Ask the supplier to list assumptions and exceptions against the same five inputs.
