Preferred Winding Parts And Technology

< p > > a href= "http://www.91se91.com/news/index_c.asp" > winding < /a > is the most frequent process of yarn Mao Yu. After winding, the Mao Yu increases by 35% to 45%.

It is generally believed that winding speed, winding tension, groove condition and yarn cleaning device are the main reasons for yarn hairiness increasing.

< /p >

< p > this is mainly due to the friction of the friction components of the yarn, which leads to the extraction of the fibers that are not deep into the yarn and form the regenerated Mao Yu.

Under the same conditions, the higher the linear speed of the winder, the greater the increase of hairiness. The winding tension increases with the increase of yarn number. When the yarn is connected with a particular number of yarn, the greater the yarn tension, the more the yarn hairiness will increase.

Generally speaking, the bakelite grooves will increase by 15% to 20% compared with the metal grooved drum. The increase of yarn hairiness is obvious by the mechanical cleaning device, and the electronic cleaning device will hardly increase the hairiness.

The line speed of the P winding machine should not be too high. The linear speed of the traditional winding machine is generally controlled at 500~600 M / min, and the linear speed of the automatic winder is generally controlled at 900~1100 M / min.

Maintaining the good condition of the winder parts is an important measure to reduce the yarn hairiness.

< p > reasonable control of temperature and humidity in the winding workshop is also good for reducing yarn hairiness. Generally, the relative humidity is controlled at about 75%, and the temperature is controlled at 30 degrees Celsius.

< p > there are many factors that affect yarn hairiness, and warping machine is one of them.

The traditional 1452 A warping machine is driven by a roller friction drive shaft. Because of the inertia of the shaft, the warp shaft does not stop completely when it stops. The shaft will slip on the roller, so that the surface of the yarn will be worn and the hairiness will be increased.

For the new warping machine, such as Benin grid warping machine, the driving mode of direct driving the warp shaft with AC motor driven hydraulic pressure regulating pump and variable speed motor can effectively reduce the occurrence of warp fuzzing caused by axial braking.

< p > followed by warping tension.

In the warping, due to the consideration of uniform yarn tension, the weight of the tension washer arranged on different positions of the cheese rack is different, and the influence on yarn hairiness is different.

The warping tension increased with the weight of the tension washer and the number of feather roots increased.

Warping speed also affects yarn hairiness.

We take 14.5 tex polyester cotton blended yarn as an example to test. The results show that the number of feather roots increases with the increase of warping speed.

< p > this is due to the increase in the warping tension after the increase of speed, and the friction between the yarn and the guide yarn components on the warping machine is intensified, and the hairiness on the surface of the yarn is increased.

The distance between warp ends is the distance between the top of the bobbin and the guide eye.

When the warping speed is constant, there must be a distance between the guide yarns and the tension is the minimum.

The distance is usually 180~200 millimeters.

Due to the difference in yarn guide distance and warp tension, the hairiness is different.
