Draw a simple layer map
Name the working face, core, reverse face and any edge, handle or binding. Record composition and dimensions for each where needed. Do not copy the composition of one face onto the entire product if the core or other face uses different materials.
Define which face contacts which surface and whether the instructions permit switching between them. A buyer should not imply that an abrasive reverse has the same compatibility as a textile face.
Separate joining methods from marketing names
Possible joining routes in this product family can include stitching, bonding or thermal techniques where the materials and design allow. The actual method, joining pattern and production sequence must be confirmed for the proposed item.
Do not state that SINOCLEAN performs a specific lamination or adhesive process on the basis of a product photograph. Ask who supplies each layer, who joins it, who converts the finished product and who checks the final item.
Inspect interfaces under relevant conditions
Wet use, squeezing, repeated handling, cleaner exposure and the proposed drying or care routine can affect the product. Assess separation, bubbles, loose edges, exposed adhesive or layers moving relative to one another where those are relevant risks.
Where a formal bond or peel requirement is needed, agree a suitable method, specimen and limit with the buyer or laboratory. An informal pull is a screen, not a universal measurement for every shape and joining system.
Use real multi-material examples carefully
The car-cleaning catalogue lists SM71005 as a microfiber car sponge with polyester, polyamide and PU, in a 23 × 12.5 × 5.5 cm format. It identifies a multi-material finished product but does not publish a complete layer-by-layer drawing or joining method.
Request those details before using the listing as a template for a new composite. An abrasive-layer variation is a separate proposal requiring its own material, interface and surface checks; it is not automatically confirmed by the existing car sponge.
| Part | Define | Check on the finished sample |
|---|---|---|
| Textile face | Composition and construction | Residue, wear and intended-surface result |
| Sponge/core | Material, shape and dimensions | Handling, deformation and recovery where required |
| Abrasive face if proposed | Material and intended use | Surface compatibility and particle release |
| Interfaces | Joining route and responsibility | Separation, loose edges and care response |
Approve the complete use description
Connect the layer drawing, material statement, sample revision and instructions. If the design changes core thickness, face fabric or joining route, review the effect on dimensions, handling, care and any claim that depended on the earlier sample.
Keep packaging and shipping compression in the approval where shape recovery matters. A successful loose sample should still be checked in the proposed selling format so the approved product is the item the customer receives.
Fields for your supplier enquiry
Provide a layer map for [proposed item], naming face, core, reverse, edge and joining route. Confirm each material and responsible production stage, finished dimensions, use/care instructions, interface checks and sample revision. Assess the packed selling unit as well as the loose sample.
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.
