Cable spinning technology
Cable spinning technology
Fabrics with a single warp and a single weft are prone to breakage during weaving. The main reason is not only that the yarn is not strong enough, but also that the yarn first fluffs and then pills under the repeated friction of the buckle, resulting in details and even yarn breakage. In order to solve this problem, many new methods have emerged, such as the use of water-soluble vinylon, the use of cold slurry twist, etc. These new processes and new technologies have certain effects. However, these methods all use other media to improve weaving efficiency. There is currently a new spinning technology, and the yarn spun using this technology has a different yarn structure from traditional single yarn. This special yarn structure ensures that the yarn itself has less hairiness and better friction resistance, which can improve the weaving efficiency of the yarn and improve the pilling resistance of the fabric. Because this yarn has a structure similar to a cable, we call this new spinning technology cable spinning.
In the spinning process of spinning engineering, a roving is usually drawn into a spun yarn. Cable spinning is different from traditional spinning. When the drafted sliver is clamped in front of the spinning machine, there is a The splitting wheel splits it into two or more fiber bundles, and those fiber bundles enter the splitting groove of the splitting wheel under the action of spinning tension; the fiber bundles in the groove wrap around themselves under the action of the spinning twisting force. The twist center rotates, thus having a certain twist; at the same time, these fiber bundles with a certain twist move downward with the winding movement of the yarn, and each fiber bundle converges at one point and moves around the twist center of the entire yarn. The rotary motion finally forms a new type of yarn with a special structure that is different from traditional yarn – cable-type spinning yarn.
According to the yarn twist theory, it can be known that the cable-type yarn has fiber bundles with a certain twist in the yarn, and the twist center of the yarn will be at the geometric center of each fiber bundle. Under the condition of the same twist, the number of fibers at the twist center in cable-type spinning is less than the number of fibers in traditional single yarn, and cable-type yarn first has the real twist of each fiber bundle, and then the real twist of all fiber bundles. With mixed twisting, the fiber transfer opportunities of the inner and outer layers are less than that of traditional single yarns, which means that the fiber head ends of cable-type spinning are much less exposed than traditional single yarns, which means that the hairiness of the yarn will be greatly reduced. Especially the hairiness is almost zero. In addition, the dividing roller is generally designed with two to four smooth and groove-free transition sections. The whiskers are not always in a divided state, but have a re-convergence period, which reduces the chance of the fibers being forcibly broken. The increased transfer of fibers results in a more complex structure between fibers than traditional single yarns, and the fibers are more tightly held together, thereby improving the friction resistance of the yarn.
Compared with traditional single yarns under the same process conditions, the special structure of cable-spun yarn determines that its wear resistance is improved by 53 to 83%, and its hairiness and hair particles are also reduced. dropped significantly. When the spindle speed is 8000rpm, the end-breakage rate of cable-type spinning is 50% lower than that of traditional single yarn with the same process.
The cable type spinning device is suitable for traditional wool spinning machines, and is simple to install and easy to use. This device has been tried in Xinjiang, Jiangsu, Zhejiang and other textile mills and has achieved ideal results. The practice of mass production by manufacturers has proven that the weaving efficiency of cable-type spinning is generally about 20% higher than that of traditional single warp and single weft of the same variety. The pilling resistance, air permeability and elasticity angle of cable-type spinning fabrics are better than those of similar traditional single wefts. yarn products. This device is spinning 72-count soybean fiber and mercerized wool blended knitted velvet. The anti-pilling ability of the garments reaches level three to level four. 4hyYjaK
