In order to prevent and control the generation of yarn black stars, properly reduce the process speed, timely remove part of cotton wax in a yarn channel, keep fibers in a stretched state in the drafting process, reduce the fiber hooking phenomenon and keep flat and straight fiber slivers smooth. Operation management is strengthened, semi-finished product protection work is well done, and high strips and messy strips are not allowed to appear. The reserve strip is kept covered by a protective cover, thereby preventing flying flowers from attaching and avoiding the phenomenon of fiber mixing caused by adhesion between the reserve strip and other semi-finished products. The roving process adopts the process principles of low vehicle speed, large gauge length, heavy pressurization, large twist factor and small back traction. Because the spun yarn is of a siro compact spinning variety, the quantity of the spun yarn is designed to the maximum on the premise of meeting the drafting requirement of the spun yarn. By doing isolation protection work, the graphene fibers are black fibers, and the phenomenon of fiber mixing caused by collision of semi-finished products and fiber floating is avoided.

The method has the advantages that key spinning special equipment such as card clothing, rubber covered rollers, rubber rings, steel rings and the like is optimized, the spinning suitability of differential yarns is improved, and production requirements and the like are met by reasonably controlling the speed and optimizing the spinning equipment.

5.

In order to prevent the problems of unsmooth strand drafting, lump yarn, yarn-saving coal ash, large difference of cvb between spindles and the like in the spinning process of spun yarn, the control on special compact spinning and drafting parts is enhanced, and the generation of lump yarn defects is strictly prevented.

The special parts for enhancing compact spinning and drafting are controlled by checking whether a bell mouth is deviated or not, whether cradle pressure is small or not, whether cradle screws are loosened or not, whether a negative pressure pipe joint falls off and leaks air, whether an air suction groove of a special-shaped pipe cover plate is blocked by hanging flowers or not, whether a tension hook part is wound with flowers or not, whether a grid ring is damaged or not, and whether transmission gears are accumulated with flowers and lack teeth or not.

The length of the first broken bar is 300mm.

Combining the waste cotton generated by pre-drawing through a second waste drawing and tearing device to form a second waste strip and tearing the second waste strip to form a second broken strip; the second waste drawing and tearing device is a second waste drawing machine for removing the foremost leather roller of the four drawing leather rollers.
