High-twist Yarn

Definition and Overview

High-twist yarn is yarn made by applying a stronger twist than usual to fibers bundled into thread. Twist refers to the process of spirally twisting fibers or single yarns together. It is used for woven warp and weft yarns, as well as yarn for knitted fabrics, and adjusts the appearance and wear feel of the textile.

There are many fibers that can be made into high-twist yarn, including cotton, linen, wool, silk, rayon, and polyester. Even with the same high-twist yarn, the finish differs in firmness and drape depending on the raw material, yarn thickness, direction and amount of twist, weaving or knitting structure, and finishing process.

Features

Because the twist is strong, the fibers are tightened, and the surface tends to feel smooth and have a crisp, cool texture. It also develops resilience, making it less likely to cling to the skin, and in thin fabrics it is sometimes used for materials that make use of sheerness and a delicate appearance.

On the other hand, because the force from the twist remains in the textile, crimping, skewing, or twisting may appear depending on the material and structure. In particular, with thin or drapey fabrics, it is important to check stability before and after cutting and the grain line.

• It is easy to achieve a dry, crisp hand.
• It has good separation from the skin and is used for spring and summer materials.
• It tends to create moderate firmness, body, and resilience.
• Depending on the raw material and structure, it can also create a drapey appearance.

Main Applications

Fabrics made with high-twist yarn are used for blouses, shirts, dresses, skirts, pants, and jackets. In addition to spring and summer clothing that emphasizes breathability and separation from the skin, they are also used for formal and dress applications that make use of surface texture and graceful drape.

In woven fabrics, the characteristics of high-twist yarn are brought out in plain weave, twill, Georgette, and voile. In knits, it may be used to give T-shirts and cut-and-sew items a dry touch.

Selection and Handling Notes

When selecting, do not judge by the label high-twist alone; check the blend ratio, industry weight, density, thickness, sheerness, stretch, and the finished hand with an actual sample. Depending on the application, it is important to sort out whether you prioritize crispness or drape and opacity.

Before cutting, let the roll rest sufficiently and check the grain line and twisting at the fabric edges. In sewing, because needle holes, puckering, and seam shrinkage are more likely to stand out in thin fabrics, adjust the needle, thread, and feed conditions through test sewing. For washing and ironing, always follow the care label and handling conditions for each fabric.

Differences from Similar Terms

High-twist yarn is a term that describes the degree of twist in the yarn and is not a fabric structure name. For example, voile and Georgette are treated as fabric names or structures, and by using high-twist yarn, their characteristic sheerness, texture, and dry hand are created.

Slubbed thread is thread with intentional unevenness in thickness, and its nature differs from high-twist yarn. Single yarn and ply yarn are classifications that indicate yarn construction. High-twist, slub, and single yarn or ply yarn can also be used in combination.

Frequently Asked Questions

Is fabric made with high-twist yarn suitable for summer?

Because fabrics made with high-twist yarn are easy to give a smooth hand and good separation from the skin, they are generally used often for spring and summer clothing. However, how hot or cool they feel also depends on the type of fiber, thickness, density, structure, and finishing process, so it cannot be judged by high-twist alone.

Does fabric made with high-twist yarn shrink easily?

The degree of shrinkage depends not only on whether it is high-twist, but also on the raw material, woven or knitted structure, dyeing and finishing process, and washing conditions. Fabrics made with high-twist yarn may show crimping or deformation caused by the force of the twist during washing, so washing tests and dimensional change checks are carried out before mass production.

What is the difference between high-twist yarn and voile?

High-twist yarn refers to the yarn itself that has been strongly twisted, while voile is a name commonly used for a thin woven fabric with sheerness. Voile may use high-twist yarn, but the two are terms from different stages: yarn and fabric.
