Reinforcement starts with yarn consistency
Tongyang Yarn supports composite and technical product manufacturers with high-tenacity, high-modulus and specialty-function yarn systems. We review the load path, laminate construction, cable design or processing environment before recommending a yarn structure.
From prototype winding and braiding through repeat supply, our goal is to help customers balance tensile performance, dimensional stability, thermal behaviour and predictable processing.

FAQs
Frequently asked questions
Answers to common questions about working with us on composite structures programs.
How do you recommend a yarn for a composite structure?
We start from the load path, geometry and processing method — winding, braiding or weaving — then propose filament type, denier and twist. Sampling against your test criteria confirms the choice before production.
Can you supply both reinforcement and binding yarns?
Yes. High-modulus reinforcement structures, binders and stitching yarns are all part of the portfolio, so preform and laminate programs can be sourced consistently.
Do you offer specialty functions such as water blocking?
Yes — water-blocking, dielectric and anti-wick constructions are available for cable and technical applications.
How do you keep strength consistent between batches?
Through controlled raw materials, fixed twist parameters and batch-level mechanical testing, with documentation supplied for your quality system.
Can you develop a custom structure for a new design?
Yes — our custom development family works directly from your specification, from denier and twist to finish, with sampling before scale-up.
