Military Enterprise Cooperation Warp Knitting Military Application Widely

along with Warp knitting industry Prosperity and development, warp knitted fabrics are increasingly becoming an indispensable resource for army building. In recent years, the marketization and openness of military procurement has also promoted more textile enterprises to participate in the R & D, production and transformation of military products, and more new textile materials and textile products have entered the ranks of military procurement. In December 17th, sponsored by the China knitwear industry association, Xi'an Polytechnic University and the knitted Association of China knitted Association organized the 2013 national military knitting materials promotion conference held in Beijing. A communication between military and warp knitting enterprises has enabled more companies to use warp knitted products in military equipment construction.

　 Military enterprise exchanges need to be strengthened

Yang Shibin, President of the China Knitting Industry Association, said that when textile products enter the military market, the channels and products are most critical. Usually, the military requires the products to be finished, serialized and low cost. Once the product is purchased by the military, it will enjoy the stable and continuous orders of the army for many years. He believes that there are several possible modes of cooperation between military and enterprise cooperation. First, the military is docking with the whole industrial chain. The two is the direct counterpart development between the military and large enterprises, and the three is the targeted research and development of military docking special enterprises. In order to further promote the further cooperation of military enterprises, the military and enterprises should strengthen exchanges on the docking of R & D and product development.

In 2015, the whole army was confronted with a new generation of combat equipment, and in 2014, the military's new generation of combat equipment will also end. Quartermaster textiles are developing products in the spirit of "three technology clusters" and "two transformations". Among them, "three technological clusters" means reducing technology clusters, functional materials clusters, and information technology clusters. In the technology alleviation cluster, the army is faced with the problems of better use of light weight and high performance textile equipment research and development. Functional materials cluster faces the use of textile materials technology such as fire prevention, stab prevention and bullet proof. The military representative reminded enterprises that the products developed jointly by the enterprises and the military were often rejected by the actual demand of the military. Therefore, enterprises should strengthen exchanges with the military in order to win greater opportunities for cooperation.

How to carry out scientific research cooperation and procurement of materials? The military representative said that the scientific research project of the army mainly came from the research on the actual needs of the army, combing out the main technical problems faced by the army, and analyzing the domestic and foreign comparative analysis. If a company collaborate with the military, it is best to start cooperation when selecting research projects for military research. This is the best time for enterprises to enter the military.

As an expert in textile and clothing co operation with the military for many years, Professor Xu Qingqing, Dean of School of art engineering, Xi'an Polytechnic University, said that warp knitted products have many unique advantages. Over the years, she has always believed that warp knitting has a better development and application prospects in the field of military industry. For this reason, she strongly promoted the close cooperation between warp knitting industry and the military.

　　 Warp knitting is widely used in military products.

High performance and multi-function Knitting material It has been widely used in the field of Quartermaster Equipment and has great potential. Professor Chen Nanliang of Donghua University said that warp knitted textiles were widely used in the army. In recent years, due to the rapid development of the knitting axial technology, the development and development of multi axial, biaxial fabrics and weft knitted axial fabrics of knitted warp knitted fabrics, especially due to the unique outstanding molding properties of knitted high performance fabrics, have attracted more and more attention to the knitting body armor materials. The warp knitted axial liner bulletproof fabric made of PPTA fiber (aramid) and the weft knitted axial lining air helmet, made of PPTA, are characterized by complex shape without cutting and molding.

In the field of protective gloves, the NBC protective gloves launched by GENTEX are made of composite materials, the outer layer is PBI/Nomex warp knitted fabric, the middle layer is a compressed foam layer impregnated with activated carbon, and the inner layer is nylon fabric, which not only has the functions of chemical protection, waterproof, cold proof, heat radiation protection, flame retardance prevention, and also has breathability and comfort.

Knitted fabrics made of knitted fabrics, military socks, cold proof sleeping bags, bullet proof clothing, bandages and other products can be weft knitted fabrics or warp knitted fabrics. Raw materials include cotton, nylon, polyester, polypropylene, polyester, etc. Usually these products are interwoven with more than two fibers. For example, the cold proof sleeping bags are made of polyester cotton interwoven fabric. After special finishing, the fabric has the characteristics of small moisture absorption, softness and heat preservation. The military mosquito net is made of warp knitted mesh fabric made of low elastic high strength polyester fiber. Warp knitted mesh fabric is widely used in military antenna and large camouflage network. Its fabric has special properties such as high strength, small surface density, grid size design, and no separation. Warp knitted mesh fabric can meet the performance requirements of special materials such as Quartermaster Equipment and other high technology fields through the selection of special raw materials, the design of the organizational structure and the adjustment of the warp knitting machine's ring forming mechanism.

　　 Warp knitted fabric It also has applications in aerospace. Semi rigid battery array is the development trend of the power system of the international space station and spacecraft. Its key mechanism is a carrier which can carry battery sheets, withstand the erosion of space environment and light weight. Advanced countries in the world use glass fiber raw materials and warp knitting technology to produce. This material requires light weight, dense, mesh structure, high strength, high modulus, resistance to atomic oxygen, and self repair ability. The glass fiber warp knitted mesh material has been applied to the "Tiangong-1" spacecraft, which provides the Tiangong-1 with the maximum generating capacity while reducing the weight of the battery wing. With the continuous development of space technology, large aperture antennas become indispensable equipment in the field of high-power communication satellites, electronic reconnaissance satellites and deep space exploration. The deployable parabolic antenna, consisting of flexible mesh, cable net and deployable supporting structure, has been applied more and more widely in aerospace field due to its light weight and small volume. The flexible mesh surface is a warp knitted mesh material produced by superfine metal wire and warp knitted weaving process. Its product requires light weight, high strength, softness, extensibility of longitudinal and lateral direction, and design of grid size. The satellite antenna project needs to overcome the problem of the connection of very fine wire. Through the special design of warping machine and warp knitting machine's corresponding mechanism, the metal mesh can be made in high quality on warp knitting machine. Through theoretical research on the structure of wire warp knitted structure, we design and weave warp knitted metal mesh material to meet the mechanical performance requirements of the antenna. At present, the metal mesh material has been tested by a series of mechanical and electrical properties to reach the international advanced level.

As the main R & D manufacturer of warp knitting machinery in China, Changzhou Run Yuan warp knitting machinery Co., Ltd. has a very systematic research and product development capability in the development and application of munitions warp knitting products. Huang Jun, director of the company's R & D department, said that warp knitting is widely used in military fields for composite use of axial warp knitted fabrics. Axial warp knitted fabric is a kind of unique warp knitted fabric produced by warp knitting machine with weft insertion system. At present, the company has studied in many fields such as aerospace, warships, automobiles, missiles, medical treatment, communication cables, parachutes, assault boats and other fields in the military field. The engineering research center set up by the company accumulated R & D cost of 50 million yuan in 2013. The center has achieved good results in the special military training clothing, aircraft elastic tapes, invisible clothing materials, ultra-high temperature protective clothing materials, stab resistant fabrics, and anti cutting fabrics, which are co operated with Jiangnan University in the military field. In the future, the development direction of the company is multi axial warp knitting machine.
