Lin Guangxing Talks About Textile Warp Knitting Technology

Along with the rapid development of warp knitting industry, technology has also been improved. Recently, the reporter has focused on the hot topic of warp knitting technology development in textile and related industries, and interviewed Lin Guangxing, vice president of China Knitting Industry Association. Lin Guangxing talked freely about the development of warp knitting industry, and clearly outlined the process of warp knitting technology in concise language.

Reporter: how do you evaluate the technological progress of domestic warp knitting industry?

Lin Guangxing: the production technology of warp knitting industry has continuously made new achievements, and the strength of a number of superior enterprises, especially the R & D strength has been steadily enhanced. What is more important and gratifying is that many advanced and practical technologies have been continuously transmitted and popularized. The technological progress of the industry is obviously advancing in an overall way, rather than simply promoting individually. This trend is already very obvious.

Reporter: you have emphasized the importance of practice in various conferences and forums. Can you talk about the importance of practice in the process of warp knitting?

Lin Guangxing: Yes, theory is the foundation and practice is the real knowledge. In the late 80s of last century, many studies of warp knitting theory and trial production of products were launched in some units, and many achievements have been made. Many progress can be called the cornerstone. For example, the research and development of axial warp knitting technology has brought new applications to users and users. When the colourful large scale light box decoration and large-span outdoor canopy facilities are displayed, when light high-strength materials are applied in construction, transportation, transportation, water conservancy, aviation, aerospace, agriculture, medicine and many other fields, whether warp knitted or weft knitted, both axially and moulded, high-end technology and products are amazing inside and outside the industry, and some are even breathtaking. Many products have been successfully built on the machine and many technologies have been passed down. Mature technology has created many product classics. Today's products, which are well known, can be seen as a magnificent development, which is benefited from practice.

Reporter: is it necessary to expand the application of raw materials in warp knitting?

Lin Guangxing: the development of raw materials is very important, but it should be done according to the mechanical characteristics of warp knitting and the needs of product application. In fact, in the initial stage of warp knitting, there are successful applications of cotton and other natural fibers in warp knitted products development. The cotton mesh vest is a vivid example. The product made in China has been popular in the international market. Cotton and other natural fibers used in lace production are also very successful in some enterprises. The natural fiber content of this end product can reach more than 70%, which is also fashionable and comfortable. Natural fiber technology needs further research and development. Warp knitting materials should be made full use of the properties of fibers. For example, the application of high-performance fibers in warp knitting is an advantage and a key point. The main material of warp knitting is, of course, chemical fiber. Warp knitted products require the chemical fiber products, and the chemical fiber industry has continuously introduced high-quality new products and injected vitality into warp knitted fabrics. The supply of all kinds of new fibers and other raw materials is still favorable for the warp knitting industry. This understanding must be firm.

Reporter: how to understand the coordinated development of warp knitting products in the three major categories?

Lin Guangxing: the application of products has been continuously expanding, and the three major products of warp knitting have been developed, the starting point is higher, the foundation is better, and some of them soon reach the international advanced level. According to industry research, the rapid development of warp knitting industry appeared after 2005. clothing The pattern of using the three major fields of industry to go hand in hand and coordinate development. The coordinated development of the three categories of products is not a set of stereotypes. Instead, it means that the development and application of warp knitted products in these three fields have formed a scale, formed a system and formed strength, and the product structure has been gradually intact. This is also the crystallization of technological progress and technology extension in the industry. Because of the advanced technology, some specifications of products meet the needs of different consumption levels, leading to international consumption to a considerable extent.

Reporter: where is the key to warp knitting products to expand their applications?

Lin Guangxing: warp knitting industry has been a group of enterprise product development to reach the international advanced level or oriented to the industry. For example, there are a number of enterprises in the research and development of multi jacquard products, a group of enterprises in the development of elastic fabric strength. In recent years, a number of enterprises have focused on leisure fabrics, and have accumulated a lot. There is also a very successful precedent for application promotion. Some underwear fabrics, jacquard decorative fabrics, automobile interior decoration fabrics, skeleton reinforcement materials and other applications and promotion, warp knitted products in the transportation, energy, aerospace and other fields of application and promotion are all professional promotion, most product names originate from warp knitting enterprises. It is still necessary to strengthen cooperation with the field of use, which is the key to expanding application. The experience of professional application and promotion needs to be promoted. The joint development of products is not enough. We should learn from the promotion methods of warp knitting products and carry out close cooperation with the field of use. It is noteworthy that many developers in the warp knitting industry believe that even if the quality fabric is developed successfully, it is not enough to research and develop. It is possible that the fabrics developed can meet all kinds of application requirements, and it is necessary to exploit the products according to the requirements and explore the unique properties.

Reporter: what do you think about the product standard of warp knitting industry?

Lin Guangxing: for a long time, enterprise standards, regional standards and industry standards should be promoted in the promotion of the whole industry. It can be seen that most clusters have distinctive products with obvious advantages in production and marketing. These advantages are international advantages and will exist for a long time, which is an important support for the warp knitting industry. The regional brand effect of warp knitting cluster has a great influence, but the standard needs to be strengthened. We should speed up the formulation of standards that reflect the actual situation of the industry, guide the development of the industry, and guide the consumption of products. Product standards must include production and utilization. Now, there are already enough enterprises to realize the importance of standards and attach importance to the guiding role of standards. They are getting important guidance according to their own development strength, and the product standards with advanced international standards are worthy of expectation.

Reporter: what is the trend of global warp knitting products?

Lin Guangxing: Global warp knitting products upgrading and industrial upgrading have been going on. The trend of development is still that the traditional products are upgraded under the background of the infiltration and promotion of all kinds of related technologies. It is the main theme to play the dominant performance of products, expand the application fields and improve the product structure. In short, of course, speed up the survival of the fittest. The development of China also clearly embodies this rule. Some developed countries have advantages in technology research, product design, part standard orientation, especially in the field of new industry and part of high-end products. Our warp knitted products have been successfully developed and produced in velvet, Terry, elastic, mesh, jacquard, lace, cylinder, spacer and full width lining weft. With the increasing proportion of various new materials, especially functional fibers and high performance fibers, with the development of warp knitted apparel and decorative products to functional, high-grade and special specifications, with the joint development and rational allocation of resources, warp knitting new industry will also show a variety of series. product Go hand in hand.
