The production process of compact spinning yarn mainly includes the following steps:
Fiber preparation: Select suitable fibers as raw materials, such as cotton fiber, polyester fiber, etc. The fiber needs to be pre-treated, including cleaning, impurity removal, etc., to ensure the quality and purity of the fiber.
Fiber opening: the pre-treated fiber is sent to the opening machine, and the fiber is loosened through the action of mechanical force and air flow, which is convenient for subsequent spinning treatment.
Fiber juxtaposition: the fiber after opening is sent to the juxtaposition machine, and the fiber is juxtaposition through the action of the juxtaposition machine to form a fiber belt.
Fiber stretching: the fiber belt is fed into the stretching machine, and the fiber in the fiber belt is stretched through the action of the stretching machine to increase the length and strength of the fiber.
Fiber spinning: the stretched fiber belt is fed into the spinning machine, and the fiber belt is spun into yarn after the spinning machine is processed. The working principle of the spinning machine is to stretch, twist and refine the fiber strips, so that the fibers are combined with each other to form yarn.
Yarn finishing: finishing the spun yarn, including cleaning, removing impurities, drying and other processing, in order to improve the quality and purity of the yarn.
Packing: The finished yarn is packed, usually with a paper tube or a plastic tube, to facilitate transportation and storage.
The above is the general production process of tight spinning yarn, the specific process may vary depending on the spinning process and fiber type. Other processes such as dyeing, warping and warping may also be involved in the production process to meet different needs and product requirements.
