Define the finish you need before choosing a texture
A glass-cleaning brief should state what an acceptable finish looks like under the chosen lighting. A general wiping brief should identify the surface and soil. A drying brief should state the area, starting water load and how wet the cloth may become before a change is needed.
These are different decisions. A construction that feels pleasant in the hand is not automatically the best choice for glass, and a photograph of a deep pile does not establish drying capacity.
Compare controlled catalogue examples
SM21001, SM21005, SM21011 and SM21016 are all listed at 80% polyester / 20% polyamide, 300 GSM and 30 × 30 cm. That makes them a useful starting group for investigating construction without changing every published specification at once. It is not a completed performance comparison.
SM21033 is listed as a glass cloth at the same blend, dimensions and GSM. Request its sample alongside the proposed textured alternatives rather than inferring a streak-free result from the catalogue name.
| Item | Catalogue description | Published common specification |
|---|---|---|
| SM21001 | Weft-knitted grid cloth | 80/20 polyester/polyamide; 300 GSM; 30 × 30 cm |
| SM21005 | Waffle towel | 80/20 polyester/polyamide; 300 GSM; 30 × 30 cm |
| SM21011 | Pearl weave | 80/20 polyester/polyamide; 300 GSM; 30 × 30 cm |
| SM21016 | Coral fleece, weft-knitted | 80/20 polyester/polyamide; 300 GSM; 30 × 30 cm |
Use the supplier’s exact construction description
The catalogue explicitly calls SM21001 a weft-knitted grid cloth and SM21016 a weft-knitted coral fleece. A waffle or pearl marketing name alone does not establish warp knitting, yarn architecture or finishing. Ask for those details if they are contractual requirements.
There is no controlled warp-versus-weft cost or durability study in this guide. To compare those production routes, obtain confirmed constructions at matched specifications and agree a test and quotation basis. Do not infer a universal winner from the knitting term.
Inspect face, reverse and edge separately
Check whether both faces match the approved sample and whether the product has a stated working face. Examine the corners, label and edge for loose material or a raised contact area. For a dual-sided or layered proposal, record each layer and its role separately.
Any claim about ultrasonic, heat-sealed or overlocked edges should identify the actual supplied item. This article does not confirm that every edge process is available or that one edge treatment is safe on all coatings.
Approve samples using the same routine
Compare new samples and samples prepared according to the proposed care instructions. Use the same surface, soil, cleaning solution and observation method. Record residue, visible lint, wet handling, wringing and the condition after use. Keep the reference cloths labelled by code.
The RFQ should combine the texture or construction with full composition, dimensions, GSM, face and reverse requirements, edge and retail pack. Attach the acceptance record to the sample approval so a repeat order is tied to the same specification rather than just the same pattern name.
A shortlist by application
For a glass brief, request SM21033 alongside a candidate texture and compare streaks and visible residue. For a general wiping brief, SM21001 grid, SM21005 waffle and SM21011 pearl provide published specification references. Treat these as candidates for testing, not as guaranteed application ratings.
For vehicle drying, consider a separate size and weight comparison using the car-cloth range rather than extrapolating from a 30 × 30 cm household cloth. SM71008 and SM71009 have the same listed size and blend but different GSM. Compare their handling and drying result on the approved vehicle finish before fixing the retail description.

Please submit [candidate codes] for [surface and routine]. Record face and reverse construction, composition, size, GSM, edge and care instructions. Identify the approved physical reference and any changed specifications.
Catalogue references and scope
The item specifications cited in this guide come from the linked SINOCLEAN catalogue entries. They identify the proposed products; they are not independent performance results. Sample routines and calculation examples are buyer guidance, not reports of completed factory or laboratory tests. Confirm the final specification and supporting evidence with the quotation.
