Compact spinning is a new spinning technology that is spun on an improved new ring spinning machine. The main spinning mechanism is: a condensation area is added in front of the traction device of the ring spinning machine, which basically eliminates the spinning twisting triangle area between the front roller and the twisting point. The following textile technology – five major advantages of compact spinning .
Five advantages of compact spinning
1. Because before twisting, the single fibers in the yarn are fully straightened and parallel to each other , and are arranged tightly, so at the nip of the twisting roller (also called the twist roller, because it prevents the transfer of twist), the diameter of the yarn becomes very small, so the “twisting triangle area” is basically eliminated. Before twisting, the single fibers are fully straightened and parallel, and there is no hairiness extending out of the main body of the yarn, so the yarn has very little hairiness, especially hairiness above 3 mm.
2. In spun yarn, since each single fiber is twisted in a straight and parallel state, when the single yarn is subjected to tension, the force on each single fiber is basically the same, so The strength of compact spinning is higher than that of traditional single yarn. And because the single fibers in the compact yarn are closely arranged and have strong cohesion with each other, this also helps to improve the strength.
3. In the compact spinning process, the yarn is gathered after completing the draft specified by the process, so the unevenness of the yarn has not been greatly improved. However, there is a finishing effect on the yarn in its gathering area, and when twisting at the twisting roller nip, the transfer of the inner and outer layers of fiber is not as strong as in the traditional process, so the compact yarn is uneven, and the thickness and detail indicators are less than Traditional yarn is better.
4. Due to the above characteristics of compact yarn, it provides very good conditions for the next process. Compact yarn has less hairiness, so it reduces the pressure of sizing, singeing and other processes. When using compact yarn as the weft yarn of a shuttleless loom, the resistance of weft insertion is greatly reduced and the efficiency of the loom is improved.
5. Because the fibers of compact yarn are closely arranged and have a smaller diameter than traditional yarns of the same number, the cloth woven with the same warp and weft density has good air permeability. The cloth surface is flat and smooth, making it an ideal high-grade yarn.
