| Best for | Finding Taiwan products certified for a named textile function | Replacing a discontinued or unavailable yarn | Using construction codes without treating classification as a machine setting, material assignment, supplier translation, or performance guarantee |
| Know before using | A listed approval applies to the identified product and function, not every output from the company; confirm scope, validity, test method, supply terms, and current certificate status. | A suggested match is a data-based shortlist, not proof that the yarn suits the pattern or maker. Yarn records can be incomplete or wrong, prices and availability vary by market, and the site uses affiliate links. Confirm the required gauge, total length, fibre behavior, construction, care, color, dye lot, accessibility, and seller terms, then make and assess a representative swatch before committing. | The record does not reproduce licensed code diagrams, verify a user's proposed code, authorize an ISO and ASTM crosswalk, select a construction, set stitch density or machine settings, prove supplier repeatability or performance, or replace the licensed standards and qualified construction, sewing, production, testing, safety, and quality review. |

| What the source establishes | The registry returned current approval records with supplier names, functional claims, and approval numbers under the Taiwan Functional Textiles system. | YarnSub's official FAQ says its matching software compares gauge, texture, yarn weight and density, fibre content, and fibre qualities such as drape and softness. Discontinued yarns remain searchable as starting points but are excluded from suggested replacements, and each yarn page provides a route to report source-data problems. | The guide cites the current public scopes and statuses of ISO 4915:1991, ISO 4916:1991, and ASTM D6193-16(2025), plus current seam-failure and seam-tensile methods; it keeps classification, translation, complete process definition, physical verification, and performance evidence separate. |
