Industry Perspective: What Is Missing From Printing And Dyeing Equipment?

In China's textile industry system, the printing and dyeing industry has a long history, and the printing and dyeing equipment manufacturing industry has followed it for decades. Development Distance. Last year, the output of printed and dyed fabrics reached 60 billion 100 million meters in China. yield It can account for more than 40% of the world's total.

Most of the printed and dyed fabrics produced in China are produced by continuous dyeing and printing equipment, and intermittent printing and dyeing equipments are mostly used for production. Small batch High grade products, dyeing and finishing of knitted fabrics are also widely used in batch equipment. Because continuous printing and dyeing equipment can solve the problem of mass printing and dyeing of textiles, we are more concerned about its development.

At present, the development of woven fabric continuous dyeing and printing equipment has reached a calm stage. The manufacturing technology has been relatively mature. The equipment flow and unit structure determined by the 74 type equipment have been able to adapt to most printing and dyeing processes after more than twenty years of improvement, and the adaptability and versatility of the equipment are getting stronger and stronger. At present, there are many enterprises producing printing and dyeing equipment, but there are not many breakthroughs in mechanical structure and mechanical performance indicators. The power of innovation is becoming weaker and weaker, and products are becoming homogenized.

The continuous scouring and bleaching and washing equipment for knitted fabrics has been developed in recent years. It is a new high efficiency continuous dyeing and finishing equipment which can adapt to the production of large quantities of knitted fabrics. Nowadays, more and more knitted garments are being chosen, and the output of knitted fabrics is increasing year by year. Traditional knitted fabric scouring and rinsing rarely uses continuous equipment, mostly in dye vats. The production efficiency is relatively low, and water is specially charged. The continuous scouring and rinsing equipment can effectively reduce the water consumption to 1/3. However, because of the traditional knitting technology, the producers are unwilling to change the process, resulting in the slow application of the continuous knitted dyeing and printing equipment. The continuous wet finishing equipment of woollen fabrics has no products in our market. Due to its high manufacturing accuracy, the demand is small, making it difficult for domestic enterprises to take a foothold in this field. In the next few years, the promotion and improvement of continuous scouring and rinsing and washing equipment is a challenging task.

In short, upgrading the mature and widely used continuous production equipment is one of the main tasks of the textile machinery field during the "12th Five-Year" period.

In recent years, new technologies and concepts have been produced, some of them have been put into use, and some of them are still in ivory towers. For many years, new technologies such as plasma desizing and ultrasonic washing are still being tested. These technologies still have various problems, and they can not replace the more practical traditional technologies. An effective way to improve the traditional equipment is to introduce automation system monitoring technology.

During the "11th Five-Year" period, the on-line detection and control technology of printing and dyeing equipment developed rapidly. Some enterprises, such as Hangzhou Kaiyuan, Changzhou Hongda and Xi'an German higher enterprises, have been leading the industry in the research and development of on-line printing and dyeing process parameters control technology. Some new products have been released and achieved gratifying results. The online monitoring of printing and dyeing equipment is a highlight of the future development of the industry. It plays a good role in stabilizing the quality of fabric processing, saving energy and reducing emissions, and cost control.

After several years of research and development, the domestic on-line monitoring and control system for printing and dyeing process parameters has solved many monitoring problems, such as tension control, multi unit accurate synchronization, pH value detection, concentration detection, moisture regain detection and control, and developed many advanced high technology products, such as alkali concentration detection system and alkali adding system, automatic distribution system of dye auxiliaries, automatic high-speed flower control system of rotary screen printing machine based on machine vision technology, humidity detection and exhaust control system of shaping machine, drying room, etc. The application of new technology effectively reduces energy consumption and water consumption in printing and dyeing production, and saves production costs. Accurate distribution of dyes and auxiliaries reduces the waste of dyes and chemicals and reduces pollution. The application of the automatic flower system not only guarantees the printing quality, but also reduces the fabric loss due to the visual measurement of flowers. The continuous dyeing machine equipped with monitoring system has obviously reduced the problem of chromatic aberration.

Some printing and dyeing high and new technology systems that have been in existence for many years are still being improved and improved. They are effective forces in the printing and dyeing equipment industry. The most representative ones are computer inkjet printing machines and computer direct manufacturing network equipment. The printing speed of inkjet printing machine has increased from 30 square meters per hour a few years ago to 140 square meters per hour, and it is developing towards higher speed indicators. The machine is no longer satisfied as a small sample machine, but has become a special and important production equipment, and a large number of high-end fabric manufacturing enterprises have been formed around it. The computerized direct network equipment has sent manual manuscripts to the museum, so that the accuracy of the printing network links has been significantly improved. After the introduction of the inkjet and wax spraying machine, we have developed laser netting equipment, and the industry standard of the direct net making machine has also been worked out.

With the gradual application of new technologies and systems in the industry, the benefits they will bring will gradually appear. Automation technology, control technology and computer technology are leading the development of printing and dyeing equipment industry. They will bring a bright future to the printing and dyeing industry.

An effective way to improve the traditional equipment is to introduce automation system monitoring technology. The online monitoring of printing and dyeing equipment is a highlight of the future development of the industry. It plays a very good role in stabilizing the quality of fabric processing, saving energy and reducing emissions, and cost control.
