Taking Black Polyester Ya Suppliers as an example, when the polyester content is below 50%, It is the same as pure cotton, it is wound around 3 times; if it exceeds 50%, it is wound around 2 times, and 100% pure polyester only needs to be wound once. The total amount of antistatic agent is generally 1. , Take innovation as the driving force, vigorously adjust the product structure, increase the development of non-cotton fiber products, establish a variety of non-cotton fiber blending models based on multi-fiber, multi-variety, small batch and multiple spinning technology combinations,
for revitalization China's cotton textile industry makes efforts. In order to reduce the net drop, increase the horizontal stripes on the side of the doffer needle teeth to improve the control ability of the fiber web. The clear flowers are difficult to roll, and there are many short piles and flying flowers.)
Layer treatment to reduce the generation of static electricity.5:1), fast transfer, small draft' process principles.3 Coarse technical measures Modified chemical fiber is generally smoother, thicker and less curled, and needs to be strengthened in the process, so the principle of 'light weight, heavy pressure, large gap' should generally be adopted.1.
The main physical indicators of hemp fiber: linear density 4500 metric, average length 17-32mm, breaking strength 5. (2) Long-staple cotton: Due to the large amount of fibers, the principle of 'less grasping, diligent grasping, more carding, less impact, early fall, and less breakage' should be adopted in the carding process; the main process parameters: grasping cotton beater speed 740r /min, the rotating speed of the carding roller is 600r/min, the comprehensive beater speed is lower than 1000r/min, the lap roller speed is 12r/min.4 cN/dtex, moisture regain rate 8.0mm.
Therefore, how to reduce the content of effective fibers in combed noil is worth studying. Therefore, after adjusting the nodding interval, the opening adjustment technology of the nipper should be used to make up for the deficiencies in the opening of the Navy Polyester Ya nipper, so that the maximum opening of the nipper is basically unchanged, and the opening timing of the nipper is basically unchanged.
Optimize the combing preparation process and improve the fiber straightness. Dialectically grasp the motion coordination relationship between the nipper, cylinder, and separation roller 1. Here, take the 90° and 111° cylinders on the E62 comber as an example to explain the time when the last cylinder needle passes the tightest point to separate the roller and cylinder (see Table 3). In order to make the front hook straight enough time, the drafting distance should be controlled to increase the distance from the fiber shift point to the front jaw; reduce the drafting roller speed appropriately.2
Optimize the strip parallel winding process to fully eliminate the fiber back hook from pre-merging to strip parallel winding, and the sliver has gone through a reverse direction, so on the strip winding machine, the fiber hook mainly appears as the back hook. If the nipper plate is opened too late, the upper nipper plate will affect the lifting of the whisker during separation and binding, causing excessive long fibers in the whisker to be intercepted by the top comb, and then brought into the combed noil by the cylinder at the next clamp time.
Table 1 Correspondence between E62 comber's nodding scale and the maximum opening of the nipper plate 1. We should first determine the division value when the last cylinder pin passes through the tightest point between the separation roller and the cylinder, and then adjust the overlap scale in the front box to optimize the reverse timing of the separation roller. I hope that colleagues will actively express their opinions and brainstorm to jointly reduce the effective fiber content in combed noil.2 According to the timing of closing and opening of the nipper plate, the cylinder is optimized to locate different types of combers.
