Conventional Polyester Yarn

The draft coefficient p affects the entire Conventional Polyester Yarn tension, if the tension is tight, p decreases; if the tension is loose, p increases. The thickness of each layer affects the tension of the large yarn. If the tension is tight, the thickness of each layer increases; if the tension is loose, the thickness of each layer decreases. The bobbin diameter affects the tension of the small yarn. If the tension is tight, the bobbin diameter increases; if the tension is loose, the bobbin diameter decreases.

First check the axial winding density of the two vehicles of this variety. The inspection method is that when the yarn is small, there is a gap of less than 0.5 mm between adjacent yarn loops. Visually, it can be seen vaguely when winding the first layer On the surface of the bobbin, when the gear of the winding part is determined, the elongation of the large, medium and small yarns is adjusted.

 After the rollers are back grinding Remove the paint color of a diameter and replace it with a new color corresponding to the diameter; 4. The rollers are placed in parallel on the tray to prevent the operation hook from being damaged and entangled; 5. The handover inspection of the handover, the bad rollers are picked out at any time . 50. What is the best cleaning time for the top roller of the spun yarn, is it according to the car wash cycle? Some factories only wash once every three months, and some factories wash cars every time they wash cars. Answer: Under normal circumstances,

the cleaning of the top roller is carried out with the wiping of the spinning device. The cleaning cycle is determined according to the company's variety, quality requirements and production management. The basic requirement is about 15 days. The raw cotton is rich in impurities, high in sugar, and the compact spinning time is shorter. Too long time will affect the use of top rollers, and then increase the yarn defects. If the cleaning cycle of the top roller is too long, 10cm mechanical waves are also prone to occur; and some problems cannot be seen on the surface.

 

Replacing the dryer is absolutely impossible for our company, which is about to retire from the city and enter the park. Therefore, we can only make small changes on the existing equipment, deepen the potential, strengthen the sense of responsibility of the air compressor personnel, put all measures into effect, minimize the moisture content of compressed air, and provide high quality for production Air compressor.
