Today, the rotor spinning machine manufacturer of Shengzhou Keyang Machinery Co., Ltd. will explain and analyze the reasons for reducing the breakage of rotor spinning.
The broken end of rotor spinning is one of the common phenomena in rotor spinning production. The rotor spinning machine applies automatic monitoring system, electronically controlled winding technology and various spinners, which can meet the requirements of spinning mills to quickly change varieties and quickly produce high-quality rotor yarn to meet market demand. The specification, batch number, twist direction and variety of raw materials for the yarn wrapping machine must be strictly verified before they are put on the machine. A twisting machine for spinning fancy yarn. The traditional fancy twister belongs to the "ring spindle yarn inspection machine", which is characterized by that the yarn feeding motion law of the feeding mechanism varies with the requirements of fancy yarn. Breaking has an impact on the yield, quality and productivity of cotton yarn. The higher the breaking rate, the greater the damage. The joint quality forms a certain length, short and thick joint, which has an obvious impact on the yarn quality. The broken end is the concrete embodiment of the management level of the spinning production process. Therefore, reducing the occurrence of broken ends in production is an important way to achieve high yield, high efficiency and high quality. The broken end of our rotor spinning is one of the common phenomena in the production and life of rotor spinning enterprises. After breaking, the yield, quality and production rate of cotton yarn will be affected to some extent by students. The higher the breaking rate, the greater the harm. The quality of the joint can form a certain length of slub, and the impact on the yarn quality is also very obvious. At the same time, the breakage is the specific content of the level of information management in the spinning production and operation process. Therefore, the occurrence of broken ends should be minimized in production, which is a very important way to achieve high yield, high efficiency and high quality.
First, the cause of broken ends in rotor spinning
The breakage of rotor spinning is mainly caused by the weakening of yarn strength ring during fiber coalescence. The rotor speed of the rotor spinning machine is very high, the centrifugal force is very large, and the negative pressure in the rotor is very high, so the air resistance of the tendrils in the rotor is also very large during the torsion process. When the fiber ring is still outside the whisker stage, its twisting ability is poor due to its small rotation. If the strength of the yarn is lower than the friction resistance, air resistance and centrifugal force of the rotor, the yarn will break. Practice and research have proved that most of the broken ends of the rotor sliver occur in the segment between the stripping point and the false twist. The specific content can be divided into the following two types: the broken end before twisting and the broken end after twisting. The main reason for the breakage before twisting is that when the enterprise transports a large number of fibers to the coagulation tank, the arrangement of fiber cells is affected during the process of coagulation and coalescence. The different forces have been seriously damaged, resulting from the leading or lagging development movement. The focus is on the impurities in semi-finished products, fine dust, dead cotton bunches, and the instability of operation and negative pressure. The broken end after twisting is mainly caused by the large loss of twist in the teaching process of twist transfer, and the larger the volume and twist of the sliver, the time change.
Analysis of the reasons for the breakage of rotor spinning enterprises
Turn to 2.1 Causes of temperature and humidity
If the relative humidity is too high, it is not easy to open and remove impurities, resulting in broken ends. If the relative humidity is too low, the fiber is loose and the adhesion is poor, and the ends are broken. The moisture regain of sliver is controlled between 6.1% and 7.2%, which is conducive to the carding and fiber transfer of sliver by the false twist texturing machine, and is conducive to rotor processing. The high moisture regain increases the difficulty of carding and conveying cotton fibers by the false twist texturing machine, and it is easy to form fiber bundles at the tooth end of the false twist texturing machine, leading to breakage.
Go to 2.2 Operation reason
The rotary float is attached to the strip, the condensate tank is not cleaned in time and embedded with impurities, there are too many dust condensate tanks, the process exhaust pipe is blocked, the process exhaust pipe is blocked, and the false twist is twisted around the flower.
