New high-speed spinning machine

Abstract

The present invention relates to a spinning equipment, in particular to a novel high-speed spinning machine, comprising a frame, a glue supply device, a filament forming device, a spinning device and a winding device, the forming part of the winding device Located on the outside of the area between the wallboards on both sides of the frame, on the other side opposite to the spinning surface, and the glue supply device and winding device are respectively located on the outside of the wallboard, the spinning device includes at least one set of spinning Spinning rolls, each set of spinning rolls includes an upper spinning roll and a lower spinning roll responsible for drafting, the two ends of the upper spinning roll and the lower spinning roll are fixed, and the gap between the upper spinning roll and the lower spinning roll It is equipped with independent drying and drafting rollers. The winding device is installed outside, so it is less corrosive to the filaments, winding equipment and its control system in an acidic environment. There is an independent drying and drafting roller between the upper spinning roller and the lower spinning roller. When drying silk strips, it can effectively control the drying temperature and time.

Description

technical field [0001] The invention relates to a spinning equipment, in particular to a new high-speed spinning machine. Background technique [0002] Pure methyl cellulose is extracted from cellulose raw material, called pulp. Treat with caustic soda and carbon disulfide to obtain orange-yellow cellulose sodium xanthate, and then dissolve it in dilute sodium hydroxide solution to become viscous spinning stock solution, called viscose. After the viscose is filtered, matured and defoamed, it is wet-spun, and the coagulation bath is composed of sulfuric acid, sodium sulfate and zinc sulfate. Sodium cellulose xanthate in the viscose reacts with sulfuric acid in the coagulation bath to decompose, and the cellulose is regenerated and precipitated. The obtained cellulose fiber becomes viscose fiber after washing, desulfurization, bleaching and drying. Viscose filament is a kind of viscose fiber, which is also made by the above process. [0003] In the process of spinning and p...

Problems solved by technology

[0033] In order to solve the problem that the winding device of the existing spinning machine is easily polluted by the water and acid solution on the spinning roll, the spinning roll integrates structures such as de-drawing, washing to remove acid, and drying, and the existing spinning machine has at least There are four spinning rollers to realize the basic function of spinning, which makes the structure of the whole machine complex and the energy consumption of the whole machine is high. In particular, a new type of high-speed spinning machine is proposed, which can ensure that the filaments are not spun during winding. The residual solution on the silk roll is polluted, and the structure of the spinning machine is simplified, the energy consumption of the spinning machine in the spinning process is reduced, and filaments with different moisture contents can be obtained according to different subsequent processing steps
