    Clothing material knowledge -- characteristics of different yarns

    Different yarn twisting processes produce different yarn structures and different product characteristics.

    Yarn depends on the cohesion and friction between the fibers. If the shape and arrangement of the fibers are not good, that is, there are bending, looping, folding, winding and other fibers, it is equivalent to shortening the length of the fiber and weakening the contact degree of the fiber, so it is easy to produce slippage between the fibers and reduce the yarn tension.

    The results show that if ring spun yarn is 1, other kinds of yarn are 0.8-0.9 for rotor spun yarn, 0.6-0.7 for air-jet spun yarn, 0.8 for vortex spun yarn and 1.15 for compact spun yarn.

    2. Hairiness

    The handle and characteristics of textile products are mainly determined by the hairiness. From the production test, it can be clearly seen that the hairiness less than 2mm has little effect on the production process and the appearance quality of the fabric, on the contrary, it will make the fabric have a natural soft handle. However, hairiness longer than 3 mm is a potential factor affecting yarn quality. Compared with the traditional ring spun yarn, the hairiness of rotor yarn, vortex yarn and compact yarn is reduced by 1 ~ 2mm. However, air jet yarn has more short hairiness due to the low number of winding fibers and less coverage of twistless core. Of course, the hairiness can be controlled by adjusting the process parameters in the spinning process.

    The comparison of yarn hairiness of different spinning methods is given. Compared with the traditional ring spun yarn, the harmful hairiness (> 3 mm) of non-traditional spinning is significantly reduced, in which the compact yarn is reduced by 80%, the air-jet yarn is reduced by 85%, and the vortex spinning yarn is reduced by more than 90%. Because the new yarn structure makes the yarn surface more stable, the hairiness increase of post-processing is significantly lower than that of traditional yarn. Especially as warp yarn, the size can be saved about 50% in sizing, which greatly improves loom efficiency and reduces weaving cost. It has been reported that the use of new yarn in the United States can reduce the cost of $2.4 per 100 m of fabric and reduce the flying flower by 72%.
