Spinning main process First, spinning principle and basic role 1, opening, removal, mixing and combing role. The compacted material must be opened to make it a fine cotton bundle. Remove impurities, blemishes, and mix evenly. Open cleaning is related to each other. Opening is the prerequisite for impurity removal and mixing. Only by opening the fibers into tiny bundles and further opening them into single fibers can the impurities be completely removed. mixing. To decompose fiber bundles into single fibers, it is not sufficient to open them only. It must also be combed. Specially demanded yarns must be combed in more detail in order to remove more impurities, defects and short fibers.
2. Uniformity, blending and drafting Both yarn and semi-finished products require a certain degree of uniformity. The semi-finished cotton sliver made by opening the combing function has a uniform thickness and cannot meet the requirements. Therefore, it is also necessary to combine and combine multiple slivers so that the uneven thickness segments have the opportunity to compensate each other and improve the uniformity. After the combined slivers are very thick, they must be spun into yarns meeting a certain degree of fineness. Normal slivers need to be drawn 100-200 times or more to produce yarn. The role of this long stretch is called drafting.
3. Twisting and winding action As the length of the sliver is attenuated, the number of fibers in the sliver decreases, the fibers become more parallel, the sliver strength decreases, and it is easy to break and generate unexpected elongation. Therefore, it is necessary to add Appropriate mobility makes it have a certain degree of strength. Spun yarn is the finished product of the spinning mill. In order to ensure that it meets certain physical and mechanical properties, satisfies the strong requirements of the yarn forming standards and a certain appearance appearance of the yarn, an appropriate degree of twist is required. This is how it works. In order to facilitate the storage and transportation of semi-finished products and finished products and the processing of the next process, it is necessary to wind the semi-finished products and yarn into a certain package form, which requires a winding action.
Second, spinning system and process flow
At present, there are two kinds of ring spinning systems, one is carding (carding) spinning system, and the other is combing spinning system.
