Wholesale viscose fiber: specification guide
A reviewable specification separates what is requested, what is offered and what is still unverified. Use these fields to prepare a factory inquiry without treating a checklist as a supplier test report.
A specification worksheet with explicit units
| Record | Write on the request | Check on the response |
|---|---|---|
| Fiber composition | Requested fiber and blend percentages | Exact article identity and declared tolerances |
| Linear density | dtex or denier, with the unit named | Method and acceptance basis |
| Cut length | mm and allowed variation, if defined | Specimen and lot connection |
| Package / quantity | Bales or other format; kg or metric tons | Net weight, packing and moisture basis |
| Yarn request, if relevant | Count system, ply, twist and luster | Do not confuse yarn count with fiber fineness |
Build a reproducible approval path
Give the proposed sample a reference number and retain its supplier article identifier. Before testing, agree the laboratory, method title and edition, sample conditioning, number of specimens and acceptance threshold. Record the date and test result against that reference. A trial approval should state what was accepted and whether a production-lot check is still outstanding. This is a procedure for obtaining evidence, not a claim that testing has been completed.
Separate fiber facts from fabric targets
Fabric construction, GSM, usable width, dye lot, shrinkage and colorfastness concern the appropriate yarn or finished fabric stage. If your project buys fiber first, retain those later-stage targets in the project brief but do not treat them as measured properties of the raw fiber. Ask the supplier to identify any change in composition, finishing or test conditions between the reference sample and bulk material.
Choose what your budget should buy
A narrower budget may favor an existing specification and a simpler documentation scope. A more demanding approval program may require extra trial material, testing and sample coordination. Compare the same currency, quantity basis, destination, packing and exclusions before choosing. High-end or budget is the buyer's preference about scope and cost; the proposed supplier's actual ability still needs review.
Read certificates in context
A requested OEKO-TEX STANDARD 100 record must be checked for issuer, validity, scope and exact proposed-product connection. A supplier quality-system record answers a different question. Consult the AATCC methods listing for method terminology and ask qualified reviewers to determine applicable methods. These references do not establish certification or application suitability.

Leave unknown values marked as open. State whether the request concerns fiber, yarn or finished fabric and include sample needs, approval timing and US destination so candidate manufacturers can respond to the same scope.
