A broad synthetic-fibre label can be useful background, but it is not a substitute for the actual material identity. Different polymer families should not be merged casually in a product record.
Textile Exchange discusses polyester and nylon as distinct synthetic-fibre families. Textile Exchange — Synthetics.
Keep the specification clear
For a character textile, retain the supplier's actual composition and product reference. Do not infer material identity from touch or a familiar surface appearance.
Evaluate the relevant property
The intended use may depend on properties of the finished textile, not only its polymer family. Connect any quantitative or care claim to appropriate evidence. A general statement about synthetics does not establish that two proposed materials are interchangeable in the same assembly.
