Four levels that a quotation should keep separate
Polymer composition names the materials. Filament architecture describes how components are arranged in an individual filament. Yarn and fabric construction describe how those filaments are assembled. The finished cloth adds dimensions, edges, colour, finishing and care requirements.
Confusion arises when a supplier uses one level as proof of another. Two polymers listed on a cloth can be present through different yarn arrangements. A photograph of the cloth face cannot resolve the filament architecture.
Monocomponent does not mean one performance grade
A monocomponent filament uses one polymer in its filament structure, but fineness, cross-section, yarn construction and finishing can still vary. It should not be equated automatically with a coarse fibre, an unsplit cleaning failure or a lower-quality product.
For a practical example, SM21039 is listed as a 100% polyamide glass cloth. That catalogue composition does not document a full upstream yarn route, splitting history or measured fineness. Use the listing to identify the sample, then ask for the technical information required by the order.
Bicomponent is a family of architectures
Bicomponent filaments can arrange polymers in structures such as sheath/core, side-by-side, segmented or islands-in-the-sea forms. Their purposes differ; the term bicomponent is not synonymous with splittable microfiber or with one cleaning mechanism.
A splittable proposal should identify which architecture is used, which components remain in the finished textile, and how the result is checked. Do not infer those answers from an 80/20 or 90/10 label alone.
| Statement | What it identifies | What it does not establish |
|---|---|---|
| 100% polyamide | Declared finished composition | Complete yarn route or cleaning result |
| 80/20 polyester/polyamide | Declared fibre percentages | A specific filament cross-section |
| Bicomponent filament | An architecture using two components | That it is splittable or superior for every task |
| Approved cleaning sample | Observed result under its recorded routine | Unrecorded upstream manufacturing details |
Make a controlled comparison
Ask each supplier to propose a finished cloth for the same surface and routine. Align dimensions, fabric weight, construction, edge and preparation where possible. If those fields differ, record them instead of attributing every observed difference to the filament type.
Assess the result on the intended task, including residue, handling and care changes. A technical architecture may be necessary for a retailer brief, but it is not a substitute for a finished-product approval.
Choose the evidence that fits the requirement
Where the contract only requires a cleaning outcome and material declaration, a detailed upstream architecture comparison may not be necessary. Where a yarn route or filament structure is part of the specification, request documentation or examination tied to the actual supplied fabric.
Keep the specimen identity, supplier statement and approval revision together. A generic diagram or report for a different construction should be labelled background information until its connection to the proposed item is demonstrated.
Fields for your supplier enquiry
Please identify [full composition], [filament architecture if required], [yarn/fabric construction] and [finished item reference] separately. State the supporting document or examination, sample revision, dimensions, GSM, edge, care and the intended cleaning task.
Sources and what this guide establishes
The item links below identify published SINOCLEAN catalogue references. They do not establish a specific upstream manufacturing route, test result, factory capability or certification. Confirm any proposal-specific information against the quotation and representative sample.
