Methods for removing foreign fibers in cotton spinning enterprises

Many people have misunderstandings or do not understand “Methods for removing foreign fibers in cotton spinning enterprises“. Next, let the editor take everyone together to share with friends and explore about “cotton spinning enterprises” Knowledge of foreign fiber removal methods”…

Foreign fibers refer to non-cotton fibers and colored fibers mixed into cotton that have a serious impact on the quality of cotton and its products, such as chemical fibers, hair, silk, hemp, plastic films, plastic ropes, colored threads (ropes, cloth) etc. Foreign fibers have the characteristics of small content, great harm and uncertainty. Not only are they difficult to remove during the fabric process, but they are also pulled or combed into shorter, thinner and more fibrous defects during the cleaning and carding process, which degrades the quality of cotton products and causes uneven coloring of the cloth. ,Affect the appearance. The problem of foreign fiber removal has always troubled fabric companies. Due to the shortage of labor resources and rising wage costs, manual picking of foreign fibers has gradually been replaced by intelligent instruments or equipment. At present, companies generally start from raw cotton manipulation and foreign fiber sorting in the blowroom process. The three stages of machine processing and winding process yarn clearing are strictly controlled, striving to remove the influence of foreign fibers to the greatest extent.
1. Strictly control the source of raw cotton
To solve the problem of foreign fibers, we must first control the raw cotton. The total amount of foreign fibers in the raw cotton directly affects the removal rate during the production process and the amount of foreign fibers in the yarn. We should look for raw cotton suppliers with good foreign fiber control and high quality reputation to ensure the quality of raw cotton. Secondly, after the raw cotton enters the factory, while conducting routine physical indicators inspection on the raw cotton, the foreign fiber content in the raw cotton should also be randomly inspected. According to the classification of foreign fibers in raw cotton from each origin and the company’s internal standards for the control of foreign fibers in raw cotton, the foreign fiber content in the raw cotton should be randomly inspected. The purchased raw cotton is classified according to its foreign fiber content for easy matching.

2. Foreign fiber machine removes foreign fibers
At present, there are two main detection methods for foreign fiber detection in the cotton cleaning process at home and abroad: electric detection and ultrasonic detection. Among them, the electric type is divided into two types: electric tube type and CCD. The main features are as follows:

In practical applications, due to many factors such as the blocking, wrapping and noise of cotton, even though a foreign fiber machine is used, foreign fibers are still leaking through, and the detection rate is not high. Therefore, the company began to implement “one line, two machines”, that is, two foreign fiber machines of different models are used in series to solve the foreign fiber blocking problem through secondary opening and secondary detection, and further improve the foreign fiber removal effect. After the cotton passes through the foreign fiber machine for the first time, most of the three yarns are removed, but there are still some three yarns that hide in blind corners, are wrapped and blocked by cotton and cannot be removed. The cotton flow passes through the foreign fiber machine for the second time and is fully mixed through the cotton box. Re-open and ensure that the three wires hidden in the blind corners are spread out evenly and the three wires that have slipped through the net are removed.

3. Self-interlacing, yarn clearing and foreign fiber removal ensure the last step
The automatic winding machine is equipped with an electronic yarn clearer with the function of detecting colored foreign fibers. After detecting foreign fibers, the spinning yarn is cut off, which can effectively remove foreign fibers. It is based on the original fully electric electronic yarn clearer and adds a fully electric foreign fiber detection device. This electricity is specially designed to detect colored fibers of the opposite sex. It can not only remove colored fibers and foreign fibers, but also colorless foreign fibers, which can effectively solve the problem of foreign fibers in bleached yarn. The methods and effects of spinning mills to control foreign fibers are limited. The fundamental way to solve the problem of foreign fibers is to strengthen the management of foreign fibers during the planting, picking and finishing stages of cotton to avoid the mixing of foreign fibers. It is hoped that domestic cotton can be improved during the picking and finishing stages. Completely solve the problem of foreign fiber mixing and improve the overall quality level of domestic cotton.
