Keep Chunqiuding and 春秋丁 together in the enquiry
For an English enquiry, write Chunqiuding (春秋丁) luggage lining and attach a sample reference. Use Chunqiuding as a transliteration of the Chinese trade name, not as a claim that a single international fabric specification exists. Do not translate the name into satin, twill or pongee until the proposed cloth's construction has been confirmed.
Record the fibre composition, yarn size and weave from the proposed cloth's technical sheet. Retain the familiar trade name alongside those details and the approved sample reference. That gives the buyer, trading team and weaving or finishing supplier a common reference even if their catalogues use different labels.
Keep 春秋丁 distinct from 春亚纺 in the enquiry. Similar-looking Chinese names are not sufficient evidence that two samples are interchangeable. If a supplier proposes another category as an equivalent, request the specification and finished swatch for that alternative and compare it explicitly.
Give the reference sample an identity that survives forwarding
Assign the sample a short code and photograph its label with the cloth. Record whether it is a loose fabric swatch, material removed from a suitcase or a finished sewn liner. Mark the visible face and note any coating or backing that can be observed. Treat visual observations as observations until the supplier confirms them technically.
When sending the enquiry between companies, keep the original code. Ask each supplier to map its own article number to that reference. A message saying 'same as the grey sample' becomes unreliable when several grey materials are being discussed. A versioned code also makes a proposed substitution easier to separate from the original request.
If the only starting point is a photograph, state that material identification is pending. Ask for candidate samples rather than approving a bulk specification from the image. Include a ruler in a detail photograph when scale matters, but do not use the photograph as proof of yarn size, composition or fabric weight.
Ask the supplier to fill the technical gaps
Send the specification fields below with the sample. Ask the supplier to enter confirmed values, identify the measurement stage and flag anything inferred. ASTM D3775 covers woven end and pick counts, while ASTM D3776/D3776M addresses mass per unit area. These give names to measurable properties; they do not certify that a material belongs to the Chunqiuding category.
Leave an unknown value marked 'to confirm' rather than filling it with a typical internet specification. A specific number copied from another seller can unintentionally become a requirement for a different cloth. Add the agreed numeric tolerances after the reference and proposed production fabric have been matched.
| Field | Information to request |
|---|---|
| Material identity | Chunqiuding (春秋丁), reference-sample code and supplier article number |
| Composition and yarns | Fibre percentages; separate warp and weft yarn descriptions with units |
| Construction | Confirmed weave; separate end and pick counts with units |
| Finished dimensions | GSM, usable width and agreed tolerances after the specified finish |
| Surface and colour | Approved face, colour reference, coating or other treatment |
| Supply form | Fabric rolls, cut panels or sewn liners, with scope clearly stated |
| Acceptance | Finished-sample approval and any agreed performance requirements |
Close the fabric decision before approving cut panels or liners
For roll supply, confirm the usable width and the finished fabric reference. For cut panels or sewn liners, add the suitcase's internal dimensions, pattern files or an agreed physical reference, seam allowances and component details. An external suitcase size label alone does not describe the available interior shape around handles, wheels and shell features.
Have the proposed fabric made into a trial liner and install it in the intended suitcase shell. The buyer should approve the internal fit, visible face, zipper clearance and assembly details before production. Retain the approved fabric and fitted-liner references together, identified by shell model and pattern revision. A material-name agreement alone does not approve the finished part.
A clear purchase description can therefore begin 'Chunqiuding (春秋丁), matching reference CQ-01' and continue with the confirmed technical sheet and supply scope. CQ-01 is an illustrative reference code, not a SHIRE LINING stock item. The name helps people find the discussion; the reference and specification define what is being ordered.
