Description
Technical Field
The invention belongs to the technical field of viscose staple fiber production, and particularly relates to a method for improving the moisture regain uniformity of viscose staple fibers.
Background
During the production and processing of the viscose staple fiber, the fiber is dried, which is an indispensable processing procedure, and the drying is mainly used for removing the redundant moisture in the fiber, so that the moisture content in the fiber reaches a certain requirement, namely a certain moisture regain is achieved. The moisture regain of the fiber has great influence on the downstream spinning forming and quality, and if the moisture regain of the fiber is not controlled well, the fiber is easy to be complained by downstream customers. Therefore, the control of the moisture regain of the fiber by viscose staple fiber manufacturers is a particularly important control index.
At present, in viscose staple fiber production enterprises, the control and the method of the moisture regain of the fiber by each manufacturer are different, and particularly the control of the uniformity of the moisture regain of the fiber is different. Some manufacturers control the uniformity of the moisture regain of the fiber by controlling the drying temperature, the drying wool-spreading effect, the drying chain speed adjustment and the like, and some manufacturers add a moisture regain humidifying device which is a device for improving the moisture regain of the textile fiber before the packaging and forming process, and the patent number is as follows: CN201020287326.4, the moisture regain of the fiber is adjusted again to achieve the effect of making the moisture regain of the fiber uniform.
However, the above-mentioned method for adjusting the uniformity of the moisture regain of the fiber does not necessarily completely solve the problem fundamentally because the factors affecting the uniformity of the moisture regain of the fiber are particularly numerous, and some of the factors cannot be solved at all by the above-mentioned method. During the production process of the viscose staple fiber, after the viscose staple fiber is spun and formed, the viscose staple fiber enters post-treatment processes, namely desulfurization, washing, bleaching, oiling and the like, in the post-treatment processes, some viscose fibers, bulk fibers or blocky fibers are generated, and if the viscose staple fiber is not opened, the problems can not be solved no matter how to adjust the drying temperature and the drying and hair spreading effect or adjust the fiber moisture regain before the viscose staple fiber is packaged and formed. Once these fibers are formed by baling without being removed, the uniformity of the moisture regain of the fibers is greatly affected. Therefore, in order to improve the uniformity of the moisture regain of the fiber, it is necessary to remove the gummy, bulky or lumpy fiber.
Disclosure of Invention
The above prior art cannot solve the problems completely and fundamentally because the uniformity of the moisture regain of the fiber has a large number of factors, some of which cannot be solved by the above method. During the production process of the viscose staple fiber, after the viscose staple fiber is spun and formed, the viscose staple fiber enters post-treatment processes, namely desulfurization, washing, bleaching, oiling and the like, in the post-treatment processes, some viscose fibers, bulk fibers or blocky fibers are generated, and if the viscose staple fiber is not opened, the problems can not be solved no matter how to adjust the drying temperature and the drying and hair spreading effect or adjust the fiber moisture regain before the viscose staple fiber is packaged and formed. The invention provides a method for improving the moisture regain uniformity of viscose fibers, which has the defect that once the fibers are not removed and formed by packing, the moisture regain uniformity of the fibers is greatly influenced.
A method for improving the uniformity of moisture regain of viscose fibers is characterized by comprising the following steps:
A. starting a fine opening fan after the fibers reach the outlet of the dryer;
B. carrying the fiber at the outlet of the dryer into a cyclone separator, and carrying out separation treatment in the cyclone separator;
C. starting fine opening cotton, and opening the fibers subjected to cyclone separation;
D. after the fibers reach the fine opening outlet, starting a condenser fan to bring the fibers in the fine opening into the condenser;
E. and starting the packaging machine, and packaging the fibers entering the packaging machine in the condenser.
The detailed steps of the step B are as follows: after the fibers are dried by the dryer, the fibers are conveyed into the cyclone separator by the fiber dryer under the action of the fine cotton opening fan, and in the cyclone separator, because of the cyclone separation effect, the fibers with larger weight in the fibers, such as the gummed silk, the bulk fibers or the blocky fibers can be separated from the fibers with normal weight and fall into the bottom of the cyclone separator.
The detailed steps of the step C are as follows: after the fiber is dried by the dryer, the fiber is sent into the cyclone separator by the fiber dryer under the action of the fine cotton opening fan.
The working principle of the invention is as follows:
after the fibre is dried through the drying-machine, under the effect of the cotton fan of smart opening, send into cyclone by the fibre drying-machine, in cyclone, owing to receive cyclone's effect, the great cellosilk of weight, nodular or massive fibre can with normal weight fibre separation in the fibre, fall into cyclone's bottom, and the fibre under the normal weight is through the cotton fan of smart opening, open in getting into the cotton of smart opening, carry into the condenser by the condenser fan at last, finally get into and pack the processing in the baling press.
The invention has the beneficial effects that:
1. the glue thread, the bulk or the block fiber in the fiber can be directly removed, and meanwhile, the sundries in the fiber can be removed, so that the uniformity of the moisture regain of the fiber can be greatly improved.
2. The technical scheme of the invention has the advantages of low investment cost, good effect, long service cycle of equipment and low maintenance cost.
3. The invention has simple process control, convenient operation and small safety risk.
