What an edge specification should include
Describe the cut perimeter, stitching or binding, corners and any label that may touch the surface. An edgeless marketing description may mean no sewn border, not literally an edge with no physical characteristics.
Ask for the final supplied cloth, including its label and packaging preparation. Evaluating only a cut piece of fabric can miss the contact area that users encounter at the corner or seam.
Overlocked edges
Overlocking uses stitching around the perimeter. The result depends on thread, stitch formation, tension, fabric stability and corner treatment. It may be appropriate for a brief, but the route name does not establish low cost, long life or suitability for every surface.
Inspect loose loops, thread ends and the edge after the proposed care routine. Record requirements for appearance, fraying and contact separately instead of assuming a stitched edge is either always safe or always damaging.
Ultrasonic and thermal descriptions
Ultrasonic processing uses vibration and local energy at the joining or cutting area; thermal cutting applies heat by other means. With suitable thermoplastic components, local softening or melting can affect the cut edge. The exact equipment and construction matter.
A heat-affected perimeter can feel different from the cloth face, but that does not establish a universal defect or advantage. Ask for the actual process and resulting edge specification, not just a premium-sounding machine name.
Compare performance at the finished-product level
Examine the perimeter and corners before and after the agreed wash routine. Evaluate lint, loose threads, stiffness, distortion and any raised area. For sensitive surfaces, test contact and compatibility using the entire cloth and appropriate handling.
Changing the edge while also changing fabric weight or pile does not isolate the effect of finishing. Where possible, compare the same base fabric with the proposed treatments and record any other differences.
| Description | Inspect on the sample | Verify with supplier |
|---|---|---|
| Overlocked | Thread, loops, corners and wash change | Stitch/thread specification |
| Ultrasonic | Finished perimeter and local stiffness | Actual cutting/joining route |
| Thermal/heat-cut | Edge condition and loose material | Treatment applicable to the fabric |
| Edgeless | Physical perimeter and surface contact | Meaning of the supplier’s description |
Confirm availability before building the retail promise
SINOCLEAN’s available material information describes edge customisation generally; it does not confirm every specific ultrasonic or thermal process for every catalogue item. Ask for a selected-code proposal and representative sample.
If the required treatment is unavailable at the target quantity or changes the sample, revise the brief and approve again. Keep the process description and the finished edge acceptance record together with the order.
Fields for your supplier enquiry
For [selected code/base fabric], propose [edge treatment] and identify any changed dimensions or construction. Include corners and label, care conditions, loose-fibre/appearance checks and intended-surface compatibility. Confirm actual process availability and sample revision.
