Knitting Machinery Industry: Trend Of Intelligence And Diversification

With the increasing demand for knitted products and the gradual strengthening of the textile industry to fine and deep processing, knitted products are gradually becoming underwear.

The characteristics of fashion.

The diversified demand of knitting products has brought great development space to knitting machinery.

At present, knitting machinery is developing in the direction of high speed, high efficiency, intelligence, high precision, diversification, differentiation, easy operation, easy maintenance, good stability and high reliability.

Component integration still needs to be strengthened

With the development of computer technology, the application of electronic jacquard technology on large circular machines has been gradually popularized.

At present, electronic jacquard technology has been successfully applied to single side jacquard circular knitting machine, double-sided jacquard circular knitting machine, and multi-function jacquard circular knitting machine, jacquard terry knitting machine, etc.

ITMA ASIA CITME 2010 recently held

On the basis of the double-sided four / six color line knitting machine introduced by Quanzhou Bai Yuan Machinery Company, the newly developed computerized color selection control system with international level has the characteristics of accurate color selection and high stability.

The direct selling panel of this machine adopts a unique heart design, effectively reducing the weaving resistance, and the maximum speed is 22 revolutions / points.

According to experts, at present, the control level of many weft knitting machines is much higher than before. Users can use PC computer to input production procedures, and complete the tasks of weaving pattern design, production data management and analysis.

Some large circular machines can not only feedback the real-time operation parameters and fault analysis of the equipment, but also input certain technology processes and production instructions through the device control panel.

Although the rapid progress of big circular machine is pleasing to the world, there is still a certain fact that the precision degree and mechanical and electrical integration level of the machined machine made by home-made large circular knitting machine are still different. These differences are mainly reflected in the fine-grained degree of roundness of large circular knitting machines, the steady running speed of large diameter circular weft knitting machines, and automatic control.

At the same time, there is still a certain gap between the domestic knitting equipment manufacturing industry and the integration of imported advanced components and domestic common parts. Sometimes, due to the unreasonable configuration of the equipment parts, the quality of the whole machine will be affected, resulting in the larger vibration and noise of the equipment when running, and the wear and tear that may occur for a long time and then affect the technological location.

In order to strengthen international integration and always aim at the frontiers of international development, large circle production enterprises should also spend more time and energy in improving the automation level of domestic equipment.

The stability of differentiation is still insufficient.

Seamless underwear, because it has no side gap, has stronger elasticity than sewing garment. It is especially suitable for knitted underwear and sports suit. This kind of clothing has been favored by consumers because of its lack of oppression and discomfort.

At present, the seamless underwear machine embodies highly mechanical and electrical integration, and gradually enhances its ability to adapt to various kinds of yarns, and is more adaptable to computer aided.

Function and so on.

Song Guangli, Professor of the Textile Institute of Tianjin University of Technology, told reporters that at the ITMA ASIA CITME 2010 exhibition this year, a total of 4 machines were displayed by Italy Saint east company, 3 of which were single sided machines and one double sided machine.

SM8TR1 is a single side moving machine, with 3 stitches on each path, 2 needle points for 3 bit stitches, and 1 needle points for needle selection.

Jumbo Chroma is a product of Sheng GE company. It has 8 channels of yarn, 2 needle points per channel and 7 feeder yarn. Besides having the characteristics of other seamless underwear machines, the high machine number is one of its characteristics. Its machine number is 40 pin /25.4mm, which is the highest seamless underwear machine with the highest machine number.

The 1 double faced machines on display are Sm9-MFS, 8 way braided 4 ring shifting, and can be converted to 12 braided without moving the ring.

These devices are highly intelligent and automatic.

The domestic seamless underwear machine, represented by Ningbo Cixing and Wuxi Jinlong, has reached the advanced level of foreign countries in terms of its basic functions. However, due to its late start, there are still many aspects needed to be further studied in terms of the accumulation of technology and technology. Therefore, there is a certain gap in the function, performance index, stability, reliability and differentiation of the domestic slit underwear machine, and there are still many links to be improved.

The single product category needs to be changed.

Composites, industrial fabrics and other warp knitted products with high added value have brought great development opportunities for warp knitting industry.

At present, China's warp knitting machine manufacturing industry is entering a period of rapid development, which is high speed, high efficiency, high stability, high adaptability and energy saving and environmental protection.

The remarkable improvement of the manufacturing level of the domestic tricot warp knitting machine is mainly reflected in the machining accuracy and the mechatronics water greatly increased, and the design and manufacture of some key parts of the equipment have made great breakthroughs.

For example, at the ITMA ASIA CITME 2010 exhibition, which was recently concluded, the Changzhou double run warp knitting machine introduced a double lined warp knitting machine lining system, which can be inserted into 24 weft yarns at a time, and the weft yarn can be accurately positioned. The speed of the equipment can reach up to 1200 rpm.

Fujian Xin Gang Textile Machinery Co., Ltd. has exhibited the HGM63/1 full computer carbon fiber multi bar jacquard warp knitting machine at this exhibition. Its jacquard system is controlled by piezoceramic, with a maximum speed of 600 rpm.

Generally speaking, the manufacturing technology of warp knitting machine has been improved progresses in recent years, but there is still a big gap between the reliability and stability of the equipment in the high-speed running state and the advanced equipment abroad.

The domestic multi comb jacquard carraschel warp knitting machine has made remarkable progress in appearance and electrical control, but it still needs to be further improved in terms of equipment processing accuracy and braiding speed.

Experts stressed that the types of warp knitting machines in China are relatively simple, mainly concentrated on products such as Tricor, multi bar Raschel, double needle bed Raschel and so on. The scope of application of these products is not very wide. They also need to further refine the product functions and expand the scope of application.

Lack of high functional refinement

Due to the increase of domestic labor costs, the demand for intelligentization and automation of knitting equipment has been increasing. The development of computerized flat knitting machine coincides with this trend.

In recent years, the production of computerized flat knitting machines has greatly exceeded the imported computerized flat knitting machines.

At present and in the future, computerized flat knitting machines will always focus on improving the production efficiency, increasing product variety and improving product quality. These three main lines are developing.

Song Guangli, a professor at the Textile Institute of Tianjin University of Technology, told reporters that at the end of the ITMA ASIA CITME 2010 exhibition, there were 19 computer flat knitting machines exhibiting in mainland China and Taiwan, of which 15 were mainly computerized jacquard flat knitting machines, and 4 were computerized collar machines.

The foreign exhibitors at the exhibition are mainly German Stoll, Japan island Jing and Switzerland.

Island fine company exhibited 3 new model machines.

Two of them are new type of applique (no dashed jacquard) flat knitting machine, the models are MACH2SIG123-SV and MACH2SIG123-SC respectively. On the basis of the original Island fine series computerized flat knitting machine, they increase the yarn guide track to 5, thus increasing the number of yarn to 40, removing the starting yarn, the waste yarn and the elastic yarn yarn mouth, and also can be used for the mosaic yarn of the inlaid flower yarn to reach 37-38.

It can be seen from the exhibition that the technological progress of domestic computerized flat knitting machines is mainly embodied in the aspects of efficiency and diversification, while there are still deficiencies in high function and refinement.

For example, Changshu Jinlong (Long Xing) company has developed a new ultra-thin yarn mouth and adjustable yarn mouth holder, so that the efficiency of weaving is obviously improved.

Ningbo Yu Ren (Ci Xing), Nantong Tianyuan, Zhejiang Vietnam and Taiwan Gao Heng and other companies have exhibited 3 needle flat knitting machines, which can solve the market demand for coarse machine models.

Nantong Tianyuan and Zhangjiagang China fly in the triangular pformation mechanism with stepper motor instead of solenoid valve, so that the reliability of the machine is enhanced, the failure rate of the machine is reduced.
