Description
Technical Field
The invention relates to an eddy spinning method, in particular to a low-hairiness eddy spinning method.
Background
The hairiness of the resultant yarn is mainly formed in the spinning process. When spinning is carried out on a ring spinning frame, a spinning triangular space exists in the process of twisting to form yarns. Part of fibers in the fiber strand at the spinning triangular space can not be effectively controlled, and the head ends of some free fibers can not be twisted into the inner layer of the yarn during twisting and are left outside the main body to form hairiness. In addition, the yarn is subjected to tension during the yarn formation process. The yarn tension causes fibers at different arrangement positions in the yarn body to be subjected to centripetal pressure with different sizes, so that the fibers are repeatedly transferred inside and outside in the radial direction of the yarn. During the transfer process, a portion of the fibers are extruded out of the veil to expose the fiber ends. The fibers at the head end are not influenced by centripetal pressure and are left on the surface of the yarn, and finally hairiness is formed. The yarn hairiness has an important influence on the quality and performance of the fabric, and can also prevent the smooth proceeding of the textile processing. The amount of the hairiness has direct influence on the production efficiency of subsequent processing and the appearance of the cloth cover of the fabric. The excessive hairiness on the surface of the yarn not only can cause the problems of unclear texture, uneven dyeing and the like of the cloth surface of the fabric, but also can easily block eyelets and gaps of yarn guiding and knitting parts to influence the knitting process. Therefore, it is necessary to further take corresponding measures to reduce the hairiness.
In order to reduce the hairiness of ring yarns, various methods have been developed. Compact spinning technology is widely adopted in the market, and hairiness of single yarn more than 3mm is greatly reduced by reducing spinning triangle areas. However, the method has large equipment investment, complex mechanism and difficult reconstruction. At present, two methods for reducing yarn hairiness by adding a hairiness eliminating device on a ring spinning machine are mainly adopted, namely a method adopting rotating airflow winding. An air jet device is arranged between a front roller and a yarn guide hook, and yarn hairiness is wound on the surface of the yarn by using rotary air flow, such as a Method and a device (Method and apparatus yarn treatment) disclosed in U.S. patent publication No. 41481779 published as No. 4/10/1979, a Method and an apparatus (apparatus yarn treatment) disclosed in U.S. patent publication No. 5263311 published as No. 8/22/1989, a Method and an apparatus (Method and apparatus for modifying spun yarn performance) disclosed in U.S. patent publication No. 5263311; a composite nozzle device capable of reducing resultant yarn hairiness, which is disclosed in Chinese patent with publication number CN102926056A and publication date 2, month 13, 2013. They mainly study the difference of the elimination effect of yarn hairiness caused by the different winding effect of changing the air jet device to make the surface fiber of yarn receive the force of different directions. These methods and devices only reduce the hairiness of the yarn and do not reduce the residual torque of the yarn. The other method is to carry out heat and moisture treatment on the fiber in the spinning process, reduce the rigidity of the fiber and improve the transfer capability of the fiber in the yarn forming process, thereby reducing the generation of hairiness.
The methods mentioned above all adopt a mechanical treatment mode to reduce the hairiness of the yarn, and have certain effects, but also have certain damage to the fiber, and also have damage to the mechanical properties such as the strength of the yarn. Therefore, it is necessary to develop a spinning method which can reduce the yarn hairiness without damaging the yarn.
