Spinning oiling device and control method

Abstract

The invention belongs to the field of spinning and discloses a spinning oiling device and a control method. The spinning oiling device comprises a body, the body is provided with a cavity, and the cavity is filled with oil mist. When fibers for spinning pass through the cavity, the oil mist in the cavity oils the passing fibers. The cavity is divided into an oil mist concentration zone filled withthe oil mist and a fiber oiling zone through which the fibers pass, the oil mist concentration zone is communicated with the fiber oiling zone, and the oil mist in the oil mist concentration zone enters the fiber oiling zone to oil the fibers passing through the fiber oiling zone. A novel spinning oiling concept is provided; through a non-contact oil mist oiling mode, the difference of the oilingquantity of a single fiber in a bundle of fibers within oiling time can be effectively reduced, the spinning process tension in a spinning process is improved, and the quality of the fibers is improved.

Description

technical field [0001] The invention relates to the field of spinning and manufacturing, and relates to a spinning oiling device and a control method. Background technique [0002] In the melt spinning process, the fiber-forming polymer is melted to form a spinning melt, which is then metered by a metering pump, and then refined through the densely distributed spinneret holes of the spinneret of the spinning assembly to form chemical fibers. [0003] The production process of chemical fiber is as follows. The fiber-forming high polymer is melted to form a uniform spinning melt, and then quantitatively metered by a metering pump, it is input to the spinning assembly, filtered and distributed in the spinning assembly, and then from the spinning The small holes of the plate flow out to form a fine fiber stream, which is stretched, thinned and solidified to form a fiber, and the fiber tow is formed into a fiber product after oiling, drafting, winding and other processes.

Problems solved by technology

However, whether it is an oil tanker or a nozzle, it is impossible to oil both sides of the fiber at the same time when oiling, and there is a time difference between the two sides of the tow or the silk, which will cause the difference in heating between the two sides of the silk condition, and the macromolecular structure inside the fiber. In addition, this kind of contact oiling will cause fluctuations in the tension of the spinning process of the tow, increasing the contact points, which will increase the fluctuations. Since the fibers are in the sensitive period of forming on the spinning process, their contact with the oiling parts There is inevitably friction, which interferes with the forming stability of the fiber. In addition, in industrialized fiber production, dozens or even thousands of filaments form a bundle, which causes some filaments to directly contact the oil when they are in contact with oil. However, some filaments can only be oiled by the penetration and infiltration of the oil agent, which inevitably leads to differences in the processes experienced by the filaments during the critical period of forming, resulting in spinning tension, Differences such as internal structure will ultimately affect the quality of fibers; especially for high-performance fibers and special-shaped fibers that require high uniformity, this difference will have a greater impact, and severe cases may cause normal production and limit high performance. fiber manufacturing
