Yarn Construction Guide

Yarn construction describes how the components of a yarn are brought together for a product requirement.

Construction is part of the application decision

Construction describes the components in a yarn and the way they are combined. A buyer brief may identify a metallic film or strip, a core or support yarn, and a twist or wrapping relationship.

Construction varies by product requirement. Use the known film, core or support yarn, wrap and sample information to describe the required structure alongside TPM, denier, twist direction, colour and application.

Original technical concept

Understanding the Components of a Yarn Construction

A yarn construction can combine different components in different ways. A buyer specification should identify the components and arrangement that are already known from the requirement or sample.

This exploded visual is a generic technical concept. The components and their arrangement should be confirmed from the buyer requirement, specification or sample.

Custom construction discussion

For a custom requirement, share the application, intended effect, available construction details and any sample or reference. The film or strip, core or support yarn and twist or wrap relationship can then be reviewed as one structure.

Why does yarn construction matter?

Construction is part of the information that connects a yarn requirement to its intended application and appearance.

Can I discuss a custom construction?

Yes. Start with the application, known product details and a sample requirement so the enquiry can be reviewed in context.
