Technical Review & Testing
Yarn Technical Laboratory
Technical review organises the parameters and reference information relevant to a metallic or zari yarn requirement, sample discussion and manufacturing plan.
What we review
Technical parameters for a clearer buyer brief
These terms create a shared vocabulary for the enquiry. Their relevance and target values come from the individual requirement; this page does not imply a fixed testing method or tolerance.
Twist level
TPM
Turns per metre provides a way to describe twist intensity where it is relevant to the yarn brief.
View TPM guide → Fineness contextDenier
Denier helps frame yarn fineness in relation to the required product and application context.
View denier guide → Construction directionTwist Direction
S or Z direction can form part of a construction or processing requirement.
View twist guide → Specification inputConstruction
Construction describes how the required yarn is framed for the technical discussion.
View construction guide → Visual referenceColour & Shade
Colour or shade direction can be discussed against a supplied or approved reference.
View colour guide → Comparison contextSample / Reference
A sample gives buyer and manufacturing teams a common reference for review.

What each technical term helps a buyer discuss
The table is a specification aid, not a statement of a particular test method, testing standard or measured output.
| Parameter | What it describes | Why the buyer may use it |
|---|---|---|
| TPM | Twist intensity expressed as turns per metre | To frame the required yarn character in the specification |
| Denier | Yarn fineness context | To discuss visual and application suitability |
| Twist direction | S or Z construction direction | To state a processing or design requirement |
| Construction | The way the yarn requirement is technically framed | To make the product brief clearer for review |
| Colour / shade | Visual direction against a reference | To align the sample and required appearance |
Requirement documentation
Information to align in the enquiry
Specific testing methods or documentation are confirmed against the individual requirement. No test certificate, COA, laboratory certificate or inspection certificate is promised by this page.
- Sample reference
- The buyer-supplied or approved comparison context.
- Product specification
- The known technical details relevant to the required yarn.
- Quality-review requirement
- The controls or documentation important to the buyer.
- Packing context
- The order information relevant to packing and dispatch preparation.
