Low-twist
Low twist refers to yarn that is given fewer twists so as to make use of the fiber’s natural loft and softness, or to the use of such yarn.

Definition and Overview
Low twist refers to a state in which the twist used to bind fibers together in spun yarn and similar yarns is relatively light. The less twist there is, the more air the fibers can trap, and the yarn becomes bulkier and softer. It is not a term for fabric names or weave structures; it is mainly a term related to yarn design.
There is no standardized criterion for the degree of low twist. Even when the term “low twist” is used, the twist strength varies depending on the material, count, single yarn or plied yarn, application, and other factors. In general, it is used when aiming for a softer texture than ordinary twisted yarn.
Texture and Function
Fabrics made with low-twist yarn are characterized by a plump thickness, a soft touch, and a light, airy feel. With cotton, it creates a gentle feel against the skin; with wool, it gives fullness and a warm appearance. When fuzziness or yarn irregularity is used to good effect, it can also create a natural, relaxed look.
On the other hand, because the force that tightens the fibers through twist is smaller, it tends to be difficult to achieve the crisp feel, cool sensation, and resilience seen in highly twisted yarns. The strength of the yarn or fabric, fuzzing, and pilling also vary greatly depending on the raw material, spinning method, density, and finishing process.
Main Applications
Low-twist yarn is used for cut-and-sewn items, sweatshirts, shirts, blouses, dresses, knitwear, and other products where softness and fullness are important. It may also be combined with brushed or washer finish processing to enhance a soft, natural appearance.
Light to medium-weight materials made with low-twist cotton yarn are used for spring and summer light clothing, as well as underwear and loungewear worn throughout the year. Low-twist wool yarn is suited to applications that require bulkiness and warmth, such as autumn and winter knitwear, jacket fabrics, and coat fabrics.
Selection and Handling Notes
When selecting fabric, do not judge it by the “low twist” label alone; check the actual texture together with the blend ratio, fabric weight, density, structure, and finishing process. It is important to confirm the surface fuzz, sheerness, stretch, recovery, and pilling from friction through swatches or prototypes according to the intended use.
Shrinkage or shape change caused by washing, moisture, or heat depends on the fiber type and finishing conditions. Before cutting, allow the fabric to relax off the roll and, if necessary, check for shrinkage. In sewing, do not pull the fabric strongly; adjust feed amount and thread tension to prevent seam shrinkage and puckering.
- If product washing is planned, confirm the post-wash dimensions and surface changes in advance.
- For materials with fuzz, check for pilling and fuzz disturbance in areas subject to frequent friction.
- For thin or low-density fabrics, pay attention to seam slippage, needle holes, and seam shrinkage.
Difference from Highly Twisted Yarn
Highly twisted yarn is yarn with a large amount of twist added. The fibers are tightened, making it easier to express a crisp feel, dry touch, cool sensation, and crinkled texture, so its texture direction is opposite to that of low-twist yarn. Highly twisted yarn is also used in spring and summer materials with a smooth feel and in woven or knitted fabrics with surface texture.
Low twist is an option when softness and bulk are desired, while highly twisted yarn is chosen when firmness and a smooth feel are desired. However, final fabric characteristics are not determined by twist alone, so even with the same fiber, compare the weave or knit structure and finishing as well.
Frequently Asked Questions
Do fabrics made with low-twist yarn shrink easily?
Shrinkage cannot be determined from low twist alone. In particular, cotton and wool can change dimensions depending on moisture, heat, finishing, and structure. Before mass production, check the fabric test results, and confirm product shrinkage and twisting through relaxation off the roll before cutting and through washing tests.
Is low-twist yarn difficult to sew?
Fabrics made with low-twist yarn can be soft and low-density, which may cause seam shrinkage, puckering, and seam slippage. However, sewability depends on the fabric structure. Perform trial sewing on the fabric edge and adjust needle size, thread count, thread tension, presser foot pressure, and feed.
Are low-twist and untwisted yarn the same?
No, they are not the same. Low twist is yarn with less twist than usual, and it still has twist to bind the fibers together. Untwisted yarn is yarn with little or no twist, or yarn made to be close to untwisted through manufacturing techniques. Check the actual twist level in the material specifications.
