polyester raw materials factory

5-1%, and it is sprayed into the cotton bales randomly with a sprayer. 2. . Spinning Pima cotton compact spinning varieties, equipped with new upper aprons and lower aprons that have been used for 1-2 months and have been maintained; the upper and lower aprons should be regularly cleaned, sorted and sorted, and the maintenance cycle generally does not exceed 2 Months. The surface is polished with a smoothness of 0. All sticky materials and intarsia adhered to the sliver channel should be cleaned with a soft dry cloth and then polished with a green environmental protection anti-winding agent.

After cleaning, blow dry with compressed air. Before the joint, check the U-shaped yarn guide rod, bell mouth, accumulation slot and front roller. The top roller is washed, cleaned, and dried with warm water at 43℃ every 3 days.3% and the sugar rate is 3. Spinning Pima cotton compact spinning varieties, equipped with 140 mesh grid ring, the maintenance principle of grid ring getting off the car is 'more blowing, less washing, frequent replacement'. (4) Roving top roller: Select a top roller with a shore temperature of about 76 degrees Shore. Around the top roller, the roving has a large stubble, and the spun yarn will wrap around the top roller and the roller as long as the broken ends are broken, making life difficult. Strengthening the configuration, maintenance and rational use of grid circles.

It is necessary to do a good job in the turnover of the top roller. (5) Spinner top roller: choose a top roller with a shore temperature of about 65 degrees Shore. Treatment with raw material sugar remover Add HD type high-efficiency raw polyester raw materials factory cotton sugar remover to 100 liters of 10-30 liters of aqueous solution, and fully stir for 5-10 minutes, then react into milky white for use.3.1mm, staple fiber index 8. (1)

Pre-roller rollers, strip-roller rollers and combing drafting rollers: choose Shaw 80-82 degree rollers, surface polished finish 0. After 48 hours in the dark, dry it and use it in the car. All quality indexes have reached the customer's requirements, see Table 2.8um, JY-Ⅱ colored AB paint is applied twice with 1:4 strokes, and it should be dried in the dark after 48 hours. Strengthen temperature and humidity control According to the requirements of Table 1, temperature and humidity adjustment, life is basically normal

The fiber Polyester Color Yarns factory transferred from the cylinder by the cylinder is first thrown to the fixed cover plate, which has a strong effect and is easy to damage the fiber. From large to small; the use of gradual spacing can make the fiber realize displacement between the cylinder and the fixed cover plate.23mm.2 Re-quantitative carding quality and problems with the process The output has increased, and the amount of carded fibers per unit time has increased several times. The distance between the cylinder and the cover plate should be determined by the state of the adhesion surface of the fiber on the cylinder surface, which mainly depends on the following factors: (1)

The surface linear velocity of the cylinder, the higher the cylinder speed is, the higher the cover plate is. Therefore, if we only increase the output of the carding machine in terms of increasing the delivery speed, it will be subject to the carding quality and the drawing capacity of the subsequent process, and the quantitative increase cannot achieve a breakthrough. Under the condition of heavy weight,

the amount of fiber carried by the cylinder card clothing increases, the needle surface load increases, the cylinder speed increases, and the thickness of the air flow of the surface layer increases. 2. But the heavy weight process is not simply to improve the sliver weight, but on the basis of satisfying the carding effect of the fiber, give full play to the mechanical and technological efficiency of the carding machine, so that the drawing quality of the subsequent process is not affected.3 Design points of the pre-carding board-spur roller, dust-knife-prick roller spacing

The pre-separating board can pre-open the fiber bundles, reducing the carding load in the main carding area.22, 0.20mm from top to bottom. The focus is on improving the fiber transfer effect and reducing quality fluctuations. (4) The longitudinal tooth pitch of the needles of the cylinder clothing is large, and the rear end of the fiber is not easy to be controlled and it is easy to rise. When the defect content of the raw material is high, moderately increasing the speed of the cover plate has a significant effect on reducing the content of sliver defects.71-0. See
