Rotor spinning method

Abstract

The invention discloses a rotor spinning method. A blowdown pipe communicated with a fiber conveying channel is arranged between a combing roller and a false twister; the other end of the blowdown pipe is connected with a blowdown air pump; and an opening / closing valve is arranged between the blowdown pipe and the blowdown air pump. Water vapor is produced in the blowdown air pump, the humidity in a rotor is extremely low, the opening / closing valve between the blowdown pipe and the blowdown air pump is opened when the humidity is less than 50%, the water vapor of the blowdown air pump is conveyed to the fiber conveying channel through the blowdown pipe and flows into the rotor through the fiber conveying channel, so that the humidity in the rotor is increased; when the humidity in the rotor is extremely high, the opening / closing valve between the blowdown pipe and the blowdown air pump is closed when the humidity is more than 75%, and the blowdown air pump stops supplementing the water vapor into the rotor. According to the rotor spinning device disclosed by the invention, the humidity in the rotor can be directionally regulated, the device can be used for spinning combed noil yarns of 14.7tex or below, the application range of the rotor spinning is widened, and cost can be saved for enterprises.

Description

technical field [0001] The invention belongs to the spinning field and relates to a rotor spinning method, in particular to a rotor spinning method with adjustable humidity in the rotor. Background technique [0002] Rotor spinning is also called open-end spinning in our country, which is a new type of spinning technology and belongs to the category of open-end spinning technology. Due to the advantages of high production efficiency, good yarn evenness, short process flow, good working environment and high degree of automation, rotor spinning is currently the most popular new spinning form. Rotor spinning has become more popular in my country, and its total production of cotton yarn is second only to ring spinning. Therefore, rotor spinning also has a greater influence in the spinning industry and plays a pivotal role. [0003] The structure of the rotor spinning device in the prior art is as figure 2 As shown, when the rotor spinning device in the prior art is used for s...

Problems solved by technology

[0005] When using rotor spinning to spin combed noil, traditional rotor spinning can only be used to spin yarns with low count and poor quality. When it is used to spin fine yarns below 14.7tex, the spinning process is interrupted The head phenomenon is more serious, and it is even difficult to form a yarn

Increasing the humidity in the workshop can be beneficial to the twisting of fibers in the rotor, but too high humidity is not conducive to the transfer of fibers in the opening roller and fiber delivery channel. Therefore, in order to enhance the spinnability of combed noil, It is necessary to regulate the humidity in the rotor in order to achieve the purpose of spinning finer yarns below 14.7tex
