The long-staple cotton fiber is slender, the gap between the licker-in and the feeder board, the gap between the Xinjinlong and the cover plate can be larger, the gap between the licker-in and the Xinjinlong can be slightly tighter, and the distance between the Xinjinlong and the doffer is the same as that of fine-staple cotton. Similarly, the tighter trend should be grasped. The structure of the double twisting unit of the double twisting machine mainly includes the spindle braking device, the spindle part of the double twisting machine, the yarn winding device, and the special device of the double twisting unit. Special equipment for the textile industry on the winder.
As the last process of spinning and the first process of weaving, winding is the link between the past and the next.“bridge”Therefore, it occupies an important position in the textile field. During the spinning process of the spinning frame, the semi-finished roving or sliver is drafted, twisted, and wound into a spinning machine. The combed sliver and the needle-carding machine combine the sliver, the needle row is drafted to improve the sliver structure, and the roving is further spun into spun yarn on the ring spinning frame, which is the main spinning machine. The speed of the cover cylinder can be lower than the average speed of medium and fine yarn counts in enterprises.
Commonly used gauge licker-in~Xinjinlong is 0.1778mm (7/1000 inch), Xinjinlong~cover is 0.2286 x 0.2032 x 0.1778 x 0.1778 x 0.4032mm (9 x 7 x 7 x 8/1000 inch) , crew ~ Xin Jinlong is 0.1778mm (7/1000 inch), Doffer ~ Xin Jinlong is 0.127mm (5/1000 inch). The adhesion of impurities and fibers in the plush cotton is strong, and the cotton drop rate is low when the rear belly process is the same. Therefore, the position of the dust collector can be appropriately lowered to shorten the distance between the bottom of the leakage and the inlet of the drum.
The length of the card feeding board should be roughly equal to the length of the raw cotton body, the length of the long staple cotton body should be about 37 mm, the length of the card feeding board should be 32-34 mm, a186g card feeding board The length of the cotton should be 30 mm, the length of the spinning long-staple cotton should be about 37 mm, and the cotton cylinder should be lengthened appropriately. The cotton wax layer of long-staple cotton is thicker, and the phenomenon of cotton wax floating on the working surface and each channel of the machine is more systematic and serious. The number of actions that can be removed should be increased to make it easier for students to remove impurities.
