Yarn Specifications and Technical Data

Practical terminology for professional buyers discussing denier, TPM, twist direction and custom yarn requirements.

Technical reference

Navigate the specification details that shape a yarn brief.

This hub helps buyers and textile teams move from broad product questions to the technical terms that support clearer selection. Denier, TPM, S-twist, Z-twist, colour, finish, packing and application context can each influence how a requirement is understood.

Use the guides below as a shared reference before discussing a custom yarn specification or a suitable product category. For technical education about yarn properties and terminology, use Zari Lab; this hub stays focused on practical specification guidance for a buyer brief.
