ZWC coordinates supplier selection and production follow-up. The requirements below are a buyer specification framework, not published performance results for a specific factory or product.
Make quotations technically comparable
| Control | Specify and record | Comparison trap |
|---|---|---|
| Fabric specification | Fibre percentages; construction; g/m²; finish; width and tolerances | The same fabric weight does not establish equivalent drape, opacity or durability. |
| Dimensional change | Wash method; cycle count; drying; conditioning; length/width changes in % | Do not compare a line-dried specimen with a tumble-dried specimen without explaining the difference. |
| Colorfastness | Separate wash, dry rubbing, wet rubbing and perspiration conditions; grade scale | A pass for one property or color does not cover the others. |
| Pilling | Method; duration or cycles; rating scale; minimum grade | A grade without the test exposure is incomplete. |
| Garment dimensions | Measurement points; size chart; tolerance in cm; before/after laundering | Do not silently average away out-of-tolerance critical measurements. |
Start with what the garment must do
A light summer top, a uniform and a stretch sports garment have different use conditions. Tell the supplier the wearer, climate, care routine and intended selling channel. Those inputs determine which properties deserve tight control and which trade-offs are acceptable.
Track the fabric through sampling and cutting
Bind the approved sample to a fabric code, mill or source, composition, finish and color lot. Before cutting, compare incoming bulk fabric with that reference. Record substitutions explicitly; a photograph cannot verify composition or fabric weight.
Interpret dimensional change correctly
Record the initial and final measurement at each defined location. Dimensional change is (final minus initial) divided by initial, multiplied by 100%; a negative result represents shrinkage under this convention. Label the sign convention because some reports express shrinkage as a positive loss. This calculation does not select the wash method or acceptance limit.
Treat trims as part of the garment
A zipper, elastic, print or label can fail even when the main fabric meets the brief. Confirm trim revision, color, dimensions, attachment and the relevant care conditions. Use the same approved bill of materials in sampling, quotation and production follow-up.
Evidence to request with the quotation
Request the specification revision, supplier and production site, quantity by style/color, report identifiers and tested materials, unit price and exclusions, sample milestones, available production slot, packing details and named shipment point. Mark each item as requested, received or checked. A supplier statement alone should not become a verified entry in the comparison matrix.
Supplier questions and answers
What fabric composition, weight and shrinkage can be controlled?
Apparel specifications should state fibre composition, fabric weight in g/m², construction and tolerances. Dimensional change needs a defined wash procedure, drying method and number of cycles, with length and width results reported separately. A sample result is relevant only to the tested fabric and finish. ZWC coordinates apparel sourcing against the approved brief rather than a universal shrinkage promise.
What colorfastness and pilling grades should buyers require?
State separate requirements for washing, dry rubbing, wet rubbing and perspiration, then specify pilling method and duration. Every grade needs its scale and method; a bare grade 4 is insufficient. Compare reports for the actual color, fibre, finish and intended use. Acceptance requirements belong in the product brief, not in a company-wide quality slogan.
What is the MOQ per style, color and size?
MOQ is confirmed against the product specification and supplier route. Ask for separate minimums by style, color, material batch and size assortment, plus repeat-order conditions. Existing materials or tooling may reduce minimums, but no universal low-MOQ quantity is promised. Record any surcharge alongside the reduced order quantity.
What are the sample lead time and on-time delivery rate?
Sampling and bulk timing are quoted after material, tooling and approval requirements are defined. ZWC does not publish a verified six-month on-time delivery rate on this page. Compare suppliers using orders due in the same period and the same milestone, including overdue open orders. Preserve the original agreed date instead of hiding delays through revised dates.
