Scientific Use Of Vortex Spinning Technology

Because Vortex spinning technology The time of introduction to the domestic use is relatively short, and the structural performance characteristics and the yarn forming mechanism of the vortex spinning machine have not reached the requirements of scientific application, either theoretically or practically, so there are many problems in the actual production. To solve these problems, we must master the production rule of eddy spinning, analyze and determine the development trend of the market, and solve the problem of insufficient management experience. At the same time, we must attach great importance to our thinking and improve it in practical work in order to make the vortex spinning technology develop healthily.

First of all, there is not enough understanding of the mechanism of vortex spinning, and the pursuit of speed is partial. Vortex spinning is a covering yarn structure consisting of two parts: core yarn and outer fiber. The length, the straightness of the fibers used and the degree of wrapping of the outer fibers will directly affect the evenness, breaking strength and wear resistance of the yarn. If we want to pursue the output, increasing the spinning speed blindly will inevitably affect the coating effect, increase the spinning breakage, reduce the yarn strength and wear resistance, make the knitted cotton fabric's pilling resistance drop, and make the spinning characteristics of vortex spinning inferior. The effective control of the outer wrapping fibers of jet vortex spinning involves the optimization of the technological parameters such as the angle of the nozzle, the diameter of the nozzle, the distance between the front roller and the hollow spindle, and the length of the guide pin. These technological parameters are all related to spinning speed. Therefore, to scientifically use the vortex spinning machine, we must fully understand the spinning mechanism of vortex spinning, optimize the technological parameters of vortex spinning, and rationally determine the spinning parameters. Do spinning Speed, to achieve maximum quality and efficiency.

Besides, there are many kinds of vortex spinning products, but few special products. Because of its yarn forming mechanism, vortex spinning is flexible. fibre The adaptability of spinning is better, so in the initial stage, most enterprises take viscose yarn as the main body. However, with the increase of production capacity and expansion of production capacity, and the wide range of viscose yarn produced by rotor spinning, the viscose yarn produced by vortex spinning is not obvious compared with rotor spunbonded yarn, and the competition is becoming increasingly fierce. The profit margins of vortex spinning are gradually narrowing. At present, some enterprises develop T/R vortex spinning. But this is also a product of ring spinning. Using vortex spinning T/R yarn instead of ring spinning T/R yarn has limited profit margins. Therefore, vortex spinning should achieve better economic benefits, and its varieties can not only take the old road of rotor spinning and ring spinning, but also develop towards differentiation, functionality and variety.

The similarity and lack of characteristics of the former spinning equipment are also one of the reasons that affect the development of vortex spinning to many varieties and differentiation. At present, most of Zhejiang vortex spinning enterprises adopt the process route of blowing carding unit and three way mixing. Blowing carding unit has the advantages of high production efficiency and labor saving, but it is suitable for processing large quantities of raw materials. In order to make the vortex spinning to the differential and functional yarns, the raw materials must be small batch and many varieties. It is difficult to adapt the blowing carding process. If we want to produce high grade, cotton blended or colored spinning vortex yarn, we need to go through the combing process and the cotton blending process. Therefore, the existing pre spinning process configuration must be adjusted to meet the needs of the development of vortex spinning to many varieties.

At present, the production environment of vortex spinning enterprises is quite different, and the control technology is not yet fully in place. Because of the higher production speed of vortex spinning, the surface temperature of draft roller and roller is higher during the production process. To avoid the phenomenon of sucking and wrapping flowers in cots and aprons, the control of temperature and humidity is very important and must be relatively stable. Therefore, the adjustment and control of temperature and humidity must be done according to the change of external climatic conditions and the use of raw materials. At present, although most of the factories are equipped with air conditioning equipment, most of them are newly established enterprises, and their understanding of the importance of temperature and humidity regulation is obviously insufficient. Some enterprises do not have full-time staffs to adjust. In order to save electricity consumption, some enterprises stop at the time of air conditioning equipment, so that production fluctuation and breakage increase, which affect the efficiency of production and the improvement of product quality.
