Screen printing on nylon fabric: start with the finish
Choose nylon screen printing ink around the actual fabric, surface finish and finished-upper test. Woven nylon, water-repellent fabric and open mesh need a trial of the full construction. The reviewed documents identify SND solvent-based waterproof nylon ink and a separate water-based ink for water-repellent nylon. Our factory team in China can review the material, basecoat, colour ink and finish together; current 37B / 37C correspondence still needs confirmation.
| Selection point | Product options | Application distinction |
|---|---|---|
| Solvent-based colour ink | 37B / 37C | Existing solvent-based nylon series labels. Current model and TDS correspondence to SND or catalogue SU remains unconfirmed; compare an approved candidate on the actual fabric. |
| Woven nylon or MONO construction | HT-2 basecoat | Existing water-based basecoat label. The catalogue lists nylon / MONO clear primers separately from colour ink, without confirming an HT-2 match or an approved ink pairing. |
| Water-repellent or anti-wicking fabric | HXL / HT-2 basecoats | Existing application-guide labels; confirm current grades and compatible layers. A water-repellent or anti-wicking finish needs evaluation on the actual fabric. |
| Nylon mesh pretreatment | SQ-363 | Existing website label. The catalogue lists YR-363 for nylon mesh and other scoped materials; its correspondence to SQ-363 and pairing with the proposed ink remain unconfirmed. |
Check the complete printed construction
Review the basecoat, colour layer and finish together. Yunrui case notes identify layer compatibility and the interval between coats as possible causes of delamination. The material guide also distinguishes ordinary mesh from woven and treated fabrics.
If ink is not sticking to nylon, show whether it releases from the fabric or between printed layers, and whether failure appears after printing, forming or testing. Record the current treatment, basecoat, colour ink, hardener, drying interval and finish. For colour bleeding, include the fabric colour and any heat-processing step. These observations define a comparison; they do not establish the cause.
Review adhesion problemsFor bending cracks: record the affected layer, conditioning, temperature, cycles and acceptance criterion. Compare the current and agreed candidate constructions under the same test conditions. A source flex count with no method does not establish a cold-flex rating. Review footwear ink cracking during flexing.
Application questions
Is 37B the same product as H37B?
Treat the complete names as separate listings. This website lists 37B in its solvent-based nylon range and H37B in water-based categories; the current reviewed documents do not confirm interchangeability or a 37B-to-SND match. Request the exact supplied model and its TDS / SDS.
Can I select a nylon ink from the fabric name alone?
The fabric name is a starting point. Surface treatment, weave, basecoat and later processing also affect the trial. A representative fabric sample helps the team review the combination.
