Twisting refers to the relative rotation of two cross-sections of the yarn, when the fibers in the yarn that were originally parallel to the yarn axis are tilted into a spiral line. Generally speaking, in the spinning process, the yarn (sliver, yarn, thread, silk) is twisted and twisted around its axis or axially wound, so that the yarn is twisted, wrapped, intertwined, etc., which are all called twisting.
Which raw materials can be Twisted
In the process of spinning production, short fibers need to be twisted in order to be spun into yarn, and filaments also need to be twisted in order to facilitate processing or increase compactness. A single yarn can also become a twisted yarn.
- Staple yarn: On the basis of overlapping the ends of the fibers, they are consolidated to make them into continuous yarns, giving the yarns a certain strength.
- Filament: Form a compact structure that is not easily damaged laterally, improve processability, improve resistance to pilling and snagging, and strong twisting makes the fabric style unique.
- Twisting single yarn into ply yarn: making the yarn structure uniform, increasing strength, reducing strength unevenness, and improving physical properties such as gloss, feel, elasticity, and elongation.
Advantages Of Twisted Yarn
- Increase the strength and wear resistance of nylon yarn (within the critical twist range) to reduce fuzzing and breakage, and improve the fastness of silk fabrics.
- Make the yarn have a certain shape or color, have good length, friction and cohesion, and strong spinnability. Give the fabric appearance with refraction, terry and other effects.
- Increase the elasticity of nylon yarn, improve the wrinkle resistance and breathability of the fabric, and make the fabric cool and comfortable to wear.
- It has certain strength, elongation and elasticity, and can withstand various mechanical forces in textile dyeing and finishing processing and use.
- It has hygroscopicity and thermal instability, which is conducive to dyeing and finishing processing and comfort when wearing.
Conclusion
In the process of yarn production, the twisting technology can make the yarn easily twisted together to form a thicker thread. The purpose of twisting is to increase the strength and elasticity of the yarn, reduce the fuzzing or breakage of the yarn, and at the same time, improve the resistance of the yarn to deformation such as stretching, twisting and deformation.
