When the mechanical condition permits, the distance between the cylinder and the cover plate should be properly adjusted to strengthen the carding effect, which can effectively reduce the cotton in the sliver. If the cylinder and the cover are both newly covered clothing, the distance between the cylinder and the cover should be enlarged by 1 to 2 inches than usual, because the new clothing has a higher sharpness.Control points of neps impurities
The main factors affecting the carding quality of the working area ofcylinder cover: card clothing state, process configuration, and mechanical state. Ensure that the clothing has sufficient sharpness, which is one of the elements to control the neps impurities.3 . One is the transitional cover plate, such as A186 type or FA201 type.5 The roundness, balance and cover root of the cylinder Wire difference is a necessary condition that restricts the correct implementation of the process. 1. The selected process configuration is also different.
Sooner or later, there will Black Polyester Yarn Manufacturers be problems. Only with a good equipment foundation can the correct implementation of the process be ensured. Before coating the new clothing, first check the straightness and roundness of the cylinder, especially the straightness of the point where a major crush accident occurs an examination. 2. In short, the correct selection of card clothing, reasonable process settings, and stable mechanical state are the necessary technical elements to reduce neps impurities. Middle and lower grades:
The needles and teeth are slightly sharp, with a sense of positive and negative directions. Drum treatment, and the welding steel plate drum has a lower probability of deformation due to the material relationship. (2) Insert the distance piece with a distance greater than 2 inches of wire into the distance point, and hold it by hand
