Before ordering, check that the fabric specification identifies the exact material, gives the conditions behind each measurement and states what counts as acceptable. Composition, GSM and width are essential starting fields; sample identity, tolerances and approval references make the sheet useful for an actual order.
Read the specification as a purchasing agreement in development. Separate supplied descriptions from measured results, and record which version applies to the order you are discussing.
Establish the identity of the fabric
Start with the supplier's fabric reference, specification revision and date. Add the sample identifier, color and finish. If the same commercial name is used for several variations, ask for a code that distinguishes the exact option.
Fiber composition should identify each component and its declared proportion. When independent composition testing is necessary, the laboratory should select a method appropriate to the blend. ISO 1833-1 provides general principles for quantitative chemical analysis, while other parts address particular mixtures. Ask which part applies to the declared blend and whether the report identifies that method. ISO 1833-1
Record seller-supplied composition as a declaration until the agreed verification is available. Appearance and hand feel can guide a discussion, but they are not a composition analysis.
Read each number with its conditions
| Field | What to clarify | Common ambiguity to resolve |
|---|---|---|
| Composition | Components, percentages and evidence basis | A broad fiber name with no blend breakdown |
| Mass per area | Unit, target, tolerance and sampling basis | A nominal GSM presented as a lot result |
| Width | Full or usable width, open or tubular form | A width figure that cannot support cutting calculations |
| Color | Reference, approved sample and assessment conditions | Approval based only on a screen image |
| Stretch | Direction, method and relevant conditions | A stretch percentage without a stated procedure |
| Finish | Exact treatment or agreed description | A functional label without performance evidence |
ASTM D3776/D3776M concerns mass per unit area, while ASTM D3774 concerns width. Read these measurements alongside the functional requirements for the finished product. ASTM mass method, ASTM width method
For unit comparisons, the GSM calculation guide connects mass and width to the quotation.
Separate targets from test results
A target states what the buyer is requesting. A result states what was measured on an identified specimen. A tolerance defines an acceptable range. Keep those roles visible instead of placing a single unexplained number in a column called quality.
For each critical property, ask for the method and edition, specimen identity, test date, relevant conditions, units and result. Check whether the report concerns the proposed color and finish or merely a related development sample.
Set acceptance criteria before commissioning the test. The method explains how to measure; your product requirement sets the limit.
If two laboratories report different values, compare sample identities and methods before treating the results as comparable.
Read certification claims narrowly
OEKO-TEX STANDARD 100 concerns testing for harmful substances. Check the certificate and the products within its scope; strength, fit and other purchasing requirements need their own evidence. OEKO-TEX STANDARD 100
The same discipline applies to any claim about recycled input or traceability: ask which scheme is claimed, what material and transaction the evidence covers, and how validity will be checked. Use the certificate details to complete that check.
Add the commercial fields needed for an order
The technical sheet should be linked to a quotation stating the price unit, quantity basis, color breakdown, packaging, delivery arrangement and approval milestones. Keep commercial terms separate where that makes them easier to update, but refer to the same fabric revision.
Ask how changes will be handled after approval. An alternative yarn, altered finish or reduced usable width may affect performance or consumption even if the supplier retains the same product name. Agree which changes require a new sample and written acceptance.
Before placing the order, confirm that the quotation, retained sample and specification all identify the same material. Resolve missing fields explicitly rather than allowing different teams to make different assumptions.
