The sliver weight should be appropriately increased. The spindle speed is 13500r/min, the front roller speed is 143r/min, the design twist factor is 380, the total draft multiple is 67. 4. 4. For this reason, the workshop controls the relative Colorful Yarn company humidity at 60-65%, the vehicle speed is low, and the top roller with good anti-winding resistance is selected. To reduce the damage to the fiber.2

Carding process Carding uses the 'multi-comb, less drop, low speed, fast transfer' process principle. 7tex Siro compact spinning blended yarn as an example to introduce the production experience of multi-component hemp yarn. (3) Antibacterial T: Because the fiber is smooth and soft, no impurities, and only a small amount of hard parallel wire, the opening and closing process should be based on the principle of 'more loose, lighter,

more combing, less falling, fine grasping'. 4. The pressure of the large and small pressure rollers should be appropriately increased to enhance the cohesion between the fibers in the cotton web and the cotton sliver, so that the cotton web does not float.21, the spindle speed is 950r/min, the front roller speed is 155r/min, the roving twist factor is 135, the roving weight is 3. Now it is made of long-staple cotton/antibacterial T/HM 50/30/20 11.35-6.,

the lap rice weight is 380g/m, and the lap length is 34. Each process has unexpectedly large drafts, many details and hairiness, and the workshop humidity should be too large to prevent the generation and accumulation of static electricity to reduce the entanglement of each process phenomenon. The hemp fiber has poor spinnability, and the fiber is easy to stick to rollers and rubber rollers, which affects the normal drafting. Reasonably set electrical clearing parameters to remove harmful yarn defects. If necessary, water the floor.1 Flower cleaning process (1) Long-staple cotton/hemp:
