  What are strong twist yarns? What are the advantages of strong twist yarn?

  In order to make yarn with certain physical and mechanical properties such as strength, elasticity, elongation, luster and handfeel, cotton yarn must be changed by twisting, and yarn twisting is achieved by fiber structure. In the twisting triangle, the width and cross-section of the cotton strip change from flat and ribbon-like to a cylindrical yarn.

  (1) Definition of twist: A yarn strip rotating 360 degrees around its axis is a twist.

  (2) Definition of twist: The number of twists in a specified length of yarn before retwisting, usually expressed as the number of twists per inch (T.P.I) or the number of twists per meter (T.P.M).

  (3) Definition of twist factor: A measure of the degree of twist in a yarn, calculated by multiplying the number of twists per unit length by the square root of the yarn density, T.M = T.P.I / square root of yarn count, T.P.I = T.M x square root of yarn count.

  (4) Definition of twist direction: The direction of inclination of the spiral formed by the rotation of the units of the yarn strip around the axis of the yarn strip when the yarn strip is in a straight position.

  (5) Definition of S-twist: The inclination of the fibers in the yarn strip in the same direction as the middle of the letter S. It is the right-hand direction or clockwise direction of the twist back yarn.

  Strong twist yarns are mainly used in weft yarns for weaving, which can produce a unique style of wrinkling on the fabric surface.

  Because of these unique effects, strong twist yarns, as special yarns, have always had a place in the yarn market. Strong twist yarn can be produced without improving equipment and adding accessories, and the technical content and added value of the product are high. However, the production of strong twist yarn is difficult and the quality of the product is difficult to control, so the producer must have certain technical ability and management experience.

  Strong twist yarn is a very common fabric, which is used in daily life to make different kinds of clothes and for other purposes. However, not many people know the characteristics of this fabric, in order to help people better understand, the following is a brief introduction to the issue, I hope it can bring help to those who need it.

It is very malleable, so it can be used to make a variety of clothes, and it is very comfortable to wear, soft to the touch, with a strong drape, and no smell after burning, so it is a healthy, green textile.

  The common twist factor is higher for woven warp yarns and lower for knitted yarns, about 3.5-3.6. Depending on the use of the yarn, there are different twist factors for yarn products. 5.0-6.5 (twist factor). High-twist yarns are usually steamed before they can be knitted, and sometimes they need to be equipped with an untwister before they can be knitted.
