What is strong twisted yarn? What are the advantages of strongly twisted yarn?
In order for the yarn to have certain physical and mechanical properties such as strength, elasticity, elongation, gloss, and feel, the cotton yarn must be changed by twisting, which is achieved by the fiber structure. Yarn twisting actually uses the relative angular displacement between the cotton yarn cross-sections to tilt the originally straight and parallel fibers and the yarn axis to change the yarn structure. During the twisting process, the thick strips gradually shrink in width and gradually fold on both sides. It is rolled into the center of the yarn line one after another to form a twisted triangle. In the twisted triangle, the width and cross-section of the sliver change, from a flat ribbon to a cylindrical yarn.
(1) Definition of twist: A 360-degree rotation of the yarn around its axis is a twist.
(2) Definition of twist: The number of twists of the yarn within a specified length before untwisting, usually the number of twists per inch (T.P.I) or per meter It is represented by the number of twists (T.P.M).
(3) Definition of twist coefficient: It is a measure of the degree of twisting of yarn, based on twists per unit length. T. M: Calculated by multiplying the number by the square root of the yarn density. T.M = T.P.I / the square root of the yarn count T.P.I = T.M The inclined direction of the spiral formed by rotating around the axis of the yarn.
(5) S twist definition: The inclination direction of the fiber in the yarn is consistent with the middle of the letter S. It is a right-hand or clockwise twisted yarn.
Strongly twisted yarn is mainly used in woven weft yarns, which can produce a unique style of wrinkles on the cloth.
Due to the above unique functions, strongly twisted yarn as a special yarn has always occupied a place in the yarn market. Strongly twisted yarn can be produced without improving equipment or adding accessories, and the product has high technical content and added value. However, the production of strongly twisted yarn is difficult and the product quality is difficult to control. Production companies must have certain technical capabilities and management experience.
Strongly twisted yarn is a very common fabric. In daily life, it is made into a variety of clothing and for other purposes. However, not many people know the characteristics of this fabric. In order to help people understand it better, here is a brief introduction to this issue. I hope it can be helpful to those in need.
Strongly twisted yarn has good dimensional stability and small washing shrinkage. Simply put, clothing or other textiles made of this fabric do not need to worry about shrinkage after cleaning.
Advantages of strong twisted yarn
Strongly twisted yarn has good luster, is very beautiful, and feels very smooth and comfortable. It’s great for making underwear and won’t harm your skin.
In addition, the strongly twisted yarn has a unique silk-like feel and is elegant and vertical. In addition to this feature, Tencel bamboo cotton fabric also has good air permeability and moisture resistance. When textiles made from it are worn in summer, people do not need to worry about its breathability and moisture resistance.
The comprehensive performance of strongly twisted yarn fully meets the requirements of modern people, and it contains a large amount of cotton and uses plant fibers, so it does not cause any harm to the human body. It has strong plasticity, so it can make a variety of clothes. It is also very comfortable to wear, has a soft hand feel, and a very strong drape. It has no smell after burning, so it is a healthy and green textile. .
The commonly used twist coefficient is that woven warp yarns are higher, while knitting warp yarns are generally lower, about 3.5-3.6. Due to different uses of yarn, there are different twist coefficient yarn products. According to Japanese textile calculation data, they are divided into: ordinary twist = 4.0 (twist coefficient), loose twist = 3.4 (twist coefficient), special loose twist = 1.32- 2.8 (twist coefficient), strong twist=5.0-5.4 (twist coefficient), special strong twist=5.0-6.5 (twist coefficient). High-twist yarn generally needs to be steamed before it can be woven, and sometimes it is necessary to install a twist remover before it can be woven. </p
