Socks & Hosiery
Start with the sock type and the yarn’s position in its construction. Requirements for the body, cuff or another section depend on the intended use and knitting setup.
Key Requirements
- Define handle, stretch and recovery targets for the sock body, cuff or other section.
- Set color and appearance expectations alongside intended wear and care conditions.
- Clarify yarn feeding and knitting requirements for the proposed sock construction.
Yarn Options to Discuss
- Material: Discuss nylon or polyester, considering any spandex component needed for the intended section.
- Structure: Compare textured and air-covered directions against the knitting setup and stretch target.
- Color: Share shade references to discuss coloration routes and agreed evaluation conditions.
What to Share
- Describe the sock type, intended use and yarn position within its construction.
- Provide the current yarn specification or a physical reference sample, when available.
- Share machine details, processing conditions and the specific issue you want to improve.
Activewear & Stretch Apparel
Describe the garment and fabric construction before discussing yarn options. Connect stretch, recovery and handle targets with how the fabric will be processed, worn and cared for.
Key Requirements
- Define stretch and recovery targets for the intended garment and fabric construction.
- Describe the required handle, color and appearance using an appropriate reference fabric.
- Identify processing conditions and relevant wear or care requirements for evaluating the yarn.
Yarn Options to Discuss
- Material: Discuss nylon or polyester, identifying whether the fabric brief requires an elastic component.
- Structure: Consider textured yarn for handle, or air-covered directions for proposed spandex combinations.
- Color: Compare coloration routes against shade references, fabric processing and agreed evaluation conditions.
What to Share
- Describe the garment’s intended use, fabric construction and the properties you want to assess.
- Provide current material details, yarn specifications or a reference fabric for comparison.
- Share processing information and explain the changes you want to evaluate through trials.


Underwear & Seamless Garments
Begin with the next-to-skin garment, its knitted structure and intended manufacturing method. Discuss comfort and appearance alongside stretch, recovery and the yarn-feeding conditions relevant to your process.
Key Requirements
- Define next-to-skin handle, stretch and recovery targets for the proposed garment construction.
- Describe color and appearance expectations, including the care conditions relevant to evaluation.
- Clarify seamless or other knitting requirements and any known yarn-feeding constraints during processing.
Yarn Options to Discuss
- Material: Discuss nylon or polyester and any spandex component required by the fabric brief.
- Structure: Evaluate textured or air-covered directions against handle, stretch and the knitting method.
- Color: Share references and care requirements to discuss coloration and fabric appearance checks.
What to Share
- Describe the finished garment, knitted structure and manufacturing method you intend to use.
- Provide the current yarn specification or a reference sample showing the desired result.
- Share machine information and identify handle, structure or processing issues you want to improve.
Other Textile Applications
Working on a different textile product? Share the finished use, fabric construction, reference sample and the result you are trying to achieve. You can start with a product or a problem even when the yarn specification is not yet clear.
Prepare Your Yarn Requirements
You do not need a complete technical specification to begin. A product, a sample or a current issue can be the starting point.
- Finished product.
- Fabric construction.
- Current yarn specification, if available.
- Target performance and color requirements.
- Reference sample or current issue.
Keep material, yarn structure, coloration and performance goals separate in your brief. These are connected choices, not interchangeable product categories.
