The spinning process is the last process of spinning production. During the spinning process, the semi-finished rovings or slivers are drafted, twisted, and wound into spinning spinning machines. The slivers are drafted on a roving frame and twisted to make rovings, and the rovings are drawn and twisted by a spinning machine to make spun yarns. The slivers are drafted on a roving frame and twisted to make rovings. The combing machine is used to comb the fibers into combed slivers and needles. The combers combine the slivers, the needle row draws to improve the sliver structure, and the rovings are further twisted into a spun yarn on a ring spinning machine.
Second, the task of spinning
1. Drafting: The rovings or slivers fed are evenly elongated to the required number of fines.
2. Twist: Add the appropriate twist to the drafts after drafting, so that the yarns have certain physical and mechanical properties such as strength, elasticity, gloss and feel.
3. Winding and forming: The spun yarn is wound on the bobbin according to certain forming requirements to facilitate transportation, storage and subsequent processing.
Third, the status of spinning process in spinning
1. The size of the spinning machine determines the size of the company.
2. The output of the spinning machine determines the production level of the company.
3, the quality of fine yarn determines the quality of the yarn.
4. How much spinning process consumes determines the cost of spinning.
5. The breakage rate when spinning thousands of spindles is an important indicator of corporate assessment.
Fourth, the main basis for measuring the quality of spinning machinery production
1, spindle and spindle speed
The production level of the spinning frame - the spinning machine is the main machine for spinning. The production and quality of the spinning yarn is a comprehensive reflection of the advantages and disadvantages of the spinning process. The production unit of a spinning machine is a spindle, and the production level of a spinning machine is often measured in terms of the output per kilo-hour (kg). The spinning mill production scale is expressed in terms of the total number of spindles that own the spinning frame.
2. Breakage rate
The yarn spun on each spindle breaks its head for a variety of reasons, often representing breakage rates as the number of breaks per thousand ingots. The rate of breakage affects labor productivity, equipment productivity, fine yarn quality and dust content in the workshop.
3, package
The spinning machine is the most energy-consuming machine in spinning production. In the production process of a spinning machine, spinning a package (coil) will stop the production. After the falling pipe yarn is replaced with an empty tube, the spinning can continue. Therefore, the size of the package affects labor productivity, equipment productivity, and energy consumption.
The spindle speed, package, and breakage rate, which are linked to each other and restrict each other, are indicators of the technical level of the spinning frame. Comprehensive considerations in society, technology, and economy are needed to determine more appropriate values.
In short, spinning is a very important process for spinning. The size of a cotton spinning mill is often expressed as the number of spinning spindles. Spinning production is the basis for determining the number of machines used in each step of a spinning mill; production quality, raw materials, machine materials, and electricity The consumption, labor productivity, equipment availability, etc. reflect the production technology and management level of spinning mills.
