What are the improvements of new spinning technology in recent years?

First, the opening and cleaning process should speed up the use of various forms of blowing and carding machines to increase the proportion of no coiling rate.

In recent years, many companies have transformed the original traditional blowing, cleaning and carding into simple blowing and carding machines. The quality of yarn and the effect of saving labor, this advanced technology should accelerate the pace of promotion and application.

Second, the carding machine is known as the "core of spinning", and various carding elements on the carding machine are its core.

Enterprises can improve the quality of cotton webs and reduce the generation of neps and short staples by adding fixed covers and other measures to ordinary A series carding machines. The newly introduced double-toothed cylinder clothing makes the density of needle teeth exceed 1400 teeth per square meter per hour, which can increase the output and carding degree of the carding machine by 30%, and reduce the short pile rate and needle surface load by 20%. And reduce the processing cost of ton yarn by 30%.

Third, it is more important to improve the sliver quality of the drawing frame than to improve the speed of the drawing frame.

The key point of drawing technology transformation is to use autoleveling technology in the last process to realize on-line inspection and monitoring of sliver quality. On the premise of improving sliver quality, the number of drawing lanes can be appropriately reduced to reduce labor, reduce consumption and increase efficiency.

Fourth, the quality of roving is closely related to the quality of finished yarn.

The enterprise transformed the conical wheel drive roving frame into a multi-motor-controlled roving frame, which effectively reduced the breakage rate during operation and increased production efficiency by about 20%. In addition, the participants believed that the technical transformation direction of the roving process can be divided into two steps. First, the conical wheel drive roving frame will be transformed into a multi-motor controlled roving frame, and the enterprises with the conditions will carry out the promotion and application of the automatic doffing and thickness connection technology of the roving. .

The fifth is to improve the automation degree of the conventional spinning frame and realize the replacement of the machine.

At present, there are two transformation methods, one is to use intelligent doffing machine to replace manual doffing; the other is to use collective automatic doffing and automatic management technology on conventional spinning frames. These two transformation methods have their own advantages and disadvantages. The former requires less investment but saves 30% of labor, and requires higher maintenance for the small doffer. The latter has a higher one-time investment, but due to the high degree of automation and intelligence of the device, the stability and reliability in operation are good, and the labor can be saved by 50% to 70%.

Sixth, choose a good automatic winder to reduce labor.

There are two types of automatic winders: yarn magazine type and tray type. At present, most enterprises use yarn magazine type automatic winders. Some companies have renovated all the yarn magazine winders that have been used for more than ten years into new tray-type automatic winders. The winding speed has been increased from 1200 m/min to 1500-1600 m/min, saving twice the labor. . The use of tray-type winders to gradually replace the original yarn bank-type winders will be another key point in the technological transformation of spinning enterprises.
