Process configuration of carding machine in polyester processing

According to the determined characteristics of polyester fibers, carding process parameters should be considered to reduce static combing, combing to improve network quality, to ensure smooth transfer and to reduce many factors in cotton webs. Grinder A spinning machine that turns fiber strands into rovings. The main function is to draft and twist, and to wind the roving into a certain package to meet the processing requirements of the spinning frame.

The structure of the double twisting unit of the double twisting machine mainly includes the spindle braking device, the spindle part of the double twisting machine, the yarn winding device, and the special device of the double twisting unit. During the spinning process of the spinning frame, the semi-finished roving or sliver is drafted, twisted, and wound into a spinning machine. The combed sliver and the needle-carding machine combine the sliver, the needle row is drafted to improve the sliver structure, and the roving is further spun into spun yarn on the ring spinning frame, which is the main spinning machine. 1. The determination of the speed of the licker-in and Xinjinlong must be comprehensively considered through the following various influencing factors.

1. The important role of reducing the carding effect of the electrostatic carding machine for students is achieved by the mutual promotion of a pair of needle surfaces in the high-speed development movement. Polyester fiber is a bad influence conductor, and the friction correlation coefficient between fibers and fibers and between fibers and metals can be very large. Static electricity is easily generated during carding, and when electricity is generated between two different objects, the friction force increases significantly. Therefore, in addition to providing appropriate oil on the surface of polyester fiber cells, and reasonably and effectively controlling the temperature of the workshop, we must also pay attention to reducing trade friction as much as possible, that is, the speed of licker-in and Xinjinlong should not be too high.

2. Improve the quality of students' carding work The quality management of carding teaching is generally expressed by the damage of fibers, the different degrees of fiber separation and the quality of sliver (focusing on fiber kinks) after processing by the carding machine. Of course, the development of carding information quality is not entirely determined by the speed of carding in China. For example, the selection of card clothing, the main gauges, the status of machinery and equipment, etc., all have an impact on the quality of our carding service. However, under the principle of insignificant level increase and fiber cell damage, it is possible to increase the speed of self-carding and analysis appropriately, which is beneficial to the elimination of cotton webs and the reduction of sliver neps, especially for polyester that contains more parallel and hard filaments. When the fiber is used, the speed of the licker-in and Xinjinlong should be appropriately increased, but the cotton-type polyester raw sliver below 20 mm should be controlled below 3%.

3. The smooth transmission of optical fibers There are many factors that affect the smooth transmission of optical fibers. Properly increasing the speed of the licker-in and the centrifugal force of fiber carding is conducive to the smooth transmission of fibers. Especially when processing polyester with poor spinnability, transfer printing is more necessary, otherwise winding phenomenon is easy to occur.

The ratio of cylinder surface speed to licker-in surface speed has almost the same effect on preventing licker-in surface spots and even affecting the cylinder surface. Due to the large speed ratio between the licker-in and the licker-in, the fibers on the licker-in can be in contact with more Jilin bell teeth, so as to transmit the fibers to the large teeth. When carding polyester fiber, due to the friction between the fiber and the needle surface, it is not easy to transfer. Therefore, compared with the carded fiber on the surface of the licker-in, the drum is generally controlled at about 2.0 (when cotton spinning, it is maintained at 1.6-1.8) 4. The licker-in, Xin King Long speed and main output of carding machine The output of the carding machine can vary according to the yarn quality requirements and the different countries of the carding machine.

In order to reduce the needle surface load when students are carding, when the output of the carding machine is increased, the cost of the licker-in and Xinjinlong speed must also be increased accordingly to ensure the quality of the system carding work. 2. Gauge When processing polyester fiber, the gauge of each part of the carding machine should follow the principle of full carding and smooth transfer. The carding gap is small, and the carding effect is good, but when processing polyester fiber, you must pay attention to the fluffy property of polyester fiber and fiber fineness and length.
