A wet spinning device and wet spinning process

Abstract

The invention provides a wet spinning device and a wet spinning process, which belong to the field of textile industry and are used to improve the strength and softness of spun yarns and reduce the hairiness of spun yarns. The wet spinning device of the present invention comprises an upper drafting roller, a lower drafting roller, a yarn guide hook, a traveler, a spinning spindle and a fiber wetting device; the wet spinning process steps include (1) The water tank is placed under the lower drafting roller, and the dripping head of the dripping device is installed above the upper drafting roller; (2) operate the operation button on the control panel to make the slurry or water drip from the dripping head; The spun fibers pass through the gap between the upper drafting roll and the lower drafting roll, and the slurry or water attached to the surface of the upper drafting roll will wet the fibers below the upper drafting roll with the rotation of the upper drafting roll; (4 ) The wetted fiber is spun into yarn under the rotation of the spinning spindle, and is wound on the spinning spindle after passing through the yarn guide hook and the traveler.

Description

technical field [0001] The invention relates to the field of textile industry, in particular to a wet spinning device and a wet spinning process. Background technique [0002] In the spinning industry, the dry spinning process is generally used at home and abroad at present. After research, it is found that the dry spinning process is not a very ideal spinning process. It has the following problems: (1) The fiber strength is very important for spinning It is a very important indicator. The test shows that the strength of natural fibers is directly proportional to the moisture content of the fiber. The higher the moisture content of the fiber, the greater its strength, and vice versa. The dry spinning strength of the fiber and the wet spinning The strength varies greatly; (2) The softness of the fiber is also a very important indicator for the spinning process. The test shows that the softness of the fiber increases with the increase of the moisture content of the fiber, and ...

[0002] In the spinning industry, the dry spinning process is generally used at home and abroad at present. After research, it is found that the dry spinning process is not a very ideal spinning process. It has the following problems: (1) The fiber strength is very important for spinning It is a very important indicator. The test shows that the strength of natural fibers is directly proportional to the moisture content of the fiber. The higher the moisture content of the fiber, the greater its strength, and vice versa. The dry spinning strength of the fiber and the wet spinning The strength varies greatly; (2) The softness of the fiber is also a very important indicator for the spinning process. The test shows that the softness of the fiber increases with the increase of the moisture content of the fiber, and the softness of the wet fiber is equal to that of the dry fiber. Several times; (3) The cohesion of dry fibers is poor, and it is easy to generate static electricity

Due to the above shortcomings in the dry spinning process, the following problems will occur. One is to affect the yarn breakage rate and reduce the labor productivity of spinning; the other is to limit the improvement of spinning count; the third is to increase the hairiness of spun yarn Especially those relatively thick and hard fibers such as jute, flax, wool, ramie, etc. perform better, which not only reduces the strength of the yarn, but more importantly, affects the improvement of the quality of the spun yarn. Clothing performance will have a greater impact

[0003] Some problems in the wet spinning process: In order to overcome the above problems, in the dry spinning process, in order to increase the moisture content of the fiber, air conditioning is generally used to humidify, that is, to increase the temperature and humidity in the spinning workshop, but this method not only water The consumption of energy such as electricity, gas, etc. is large, the production cost is high, and the humidity in the fiber is relatively small, the moisture content of the fiber can only be increased by about 3%, and the strength and softness of the fiber are small, which is far from meeting the requirements of spinning. People use wet spinning process, and it is first used in flax spinning, but because the wet spinning process is to humidify the roving, that is, the roving is completely soaked in water, and the moisture content is completely saturated, although the strength of the fiber The softness and softness have been greatly improved, but due to the certain viscosity of water, it will inevitably bring great difficulties to the drafting of the spun yarn. It can reduce the speed of the front roller and reduce the draft ratio, which will inevitably greatly reduce the spun yarn output and greatly increase the production cost, so it has not been widely used
