Shantou Customs Promotes Textile Industry In Eastern Guangdong To Promote Automation

< p > recently, the Shantou Customs said that Shantou customs implemented the national structural tax relief policy and encouraged the textile enterprises in the customs area to introduce advanced foreign equipment and advanced technology, improve the level of product technology, reduce labor costs, improve competitiveness and promote the pformation and upgrading of traditional industries in eastern Guangdong.

Before we need 5000~6000 < a href= "http://www.91se91.com/news/index_c.asp" > workers < /a >, only about 20 workers are needed now, which can effectively alleviate labor shortage.

< /p >

< p > > a href= "http://www.91se91.com/news/index_c.asp" > knitting technology > /a > has also been greatly improved. Many complex processes can only be accomplished easily by design programmers on the computer. The computerized horizontal knitting machine can accomplish many complex workmanship that can not be finished by hand, so that the products can be trusted by more customers.

In the past 3 years, the total export volume of the company has reached US $156 million, with an annual export growth rate of 28.3%.

< 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.

< /p >

< p > 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.

< /p >

< p > the warping tension increases with the weight of the tension washer, and the number of feather roots increases.

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 >

< 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.

< /p >

< p > 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.
