　　 Through a production line, the flexible production of automobile ceiling, cushion and other automotive products is realized, which is well received by automobile interior decoration enterprises; In addition to shale gas exploitation, it also extends to the application fields of trenchless repair of urban pipeline network and emergency rescue of water regime events.

　　 On July 20, Chen Siqi, Deputy Secretary General of textile light foundation, Li Yuhao, Deputy Secretary General of China Industrial Textiles Industry Association, and other four people visited Jiangsu Yingyang non-woven machinery Co., Ltd. (hereinafter referred to as "Jiangsu Yingyang") which had won the first prize of "textile light" science and technology award of China Textile Industry Federation Wuxing Technology Co., Ltd. (hereinafter referred to as "Wuxing technology") understands the industrialization progress and technology update of the project.

　　 Project Name: key technology and equipment for flexible composite production of vehicle Nonwovens

　　 Honor: first prize of science and technology award of China Textile Industry Federation in 2019

　　 Jiangsu Yingyang was founded in 1992. Fan Liyuan, the chairman of the board, decided to be the first in the field of non-woven machinery and equipment at the beginning of the company. In his view, technology research and development is the foundation of the establishment of enterprises. He devoted all his energy and enthusiasm to his beloved non-woven business without any regrets. Over the past 30 years, Yingyang, Jiangsu Province, has been closely following the national development strategy, closely following the needs of industry development and downstream customers, and has continuously achieved technological breakthroughs. At the same time, it also contributes to the progress of science and technology in the industry.

　　 In the exhibition hall full of modern atmosphere, Liu Lu, assistant general manager of Jiangsu Yingyang, introduced the company's development history, digital production workshop and intelligent nonwoven equipment.

　　 In the forum, Yu Shufa, director of Jiangsu Yingyang general manager's office, introduced the project situation and related progress of "key technology and equipment for flexible composite production of vehicle nonwovens".

　　 Nonwovens for vehicles have the characteristics of high resilience, sunlight resistance, heat resistance, high color fastness, wear resistance of more than 10000 times, safety and non-toxic. The existing production equipment has single function and can not adapt to the mixing of various raw materials and composite on-line molding. The products can not meet the multi-functional requirements, which seriously restricts the popularization and application of composite vehicle nonwovens.

　　 The project innovates the multi process flexible composite methods such as needling, powder spreading and hot melting, solves the problem of single function of the production line, and realizes on-line composite one-time molding from fiber to various products (needle punched cloth / fiber mesh, needle punched cloth / PP film, needle punched cloth / fiber web / PP film); The key mechanism of multi fiber blending carding was invented, which solved the industrial problems of fiber breakage, delayed transfer and uneven meshing during blending carding, and the evenness of fiber web was less than 2%, and the blending output of carding machine was increased by 30%; The load distribution technology and conjugate balance technology of acupuncture machine were developed, which solved the imbalance problem of heavy load and high-speed operation of acupuncture machine, realized 1800 times / min high-frequency needling molding of 2000g / m2 high-G vehicle nonwovens, and the acupuncture efficiency was increased by 50%; A complete set of flexible composite equipment for vehicle nonwovens was developed. The expert system for process parameters and the Internet of things system were developed to realize the digital production of vehicle nonwovens.

　　 According to Yu Shufa, the successful R & D of the project has reduced the comprehensive investment of downstream user enterprises by 60%, increased the production efficiency by 30%, and reduced the production cost by 40%. The project equipment has enhanced the international competitiveness of China's automotive nonwovens, and has made positive contributions to the structural adjustment, transformation and upgrading of the industrial textiles industry.

　　 Project Name: key technology of braiding and compounding for large diameter high pressure resistant fracturing fluid delivery pipe

　　 Honor: first prize of science and technology award of China Textile Industry Federation in 2020

　　 China is rich in shale oil and gas reserves, and the exploitation of shale oil and gas plays an important role in ensuring energy security. Hydraulic fracturing is the main means of shale oil and gas exploitation. The long-distance transportation hose of fracturing fluid is one of the most important materials to determine the fracturing production efficiency. The problems of small caliber and low blasting pressure commonly exist in the existing products, which leads to the small delivery flow and low production efficiency; And the single length is short and there are many joints, so the risk of fracturing fluid leakage is high; In addition, the coating structure is unreasonable and the production process is long. The key technology of braiding and compounding of super large diameter high pressure resistant fracturing fluid delivery pipe effectively solves the above problems.

　　 Zhou Gang, vice president of Wuxing science and technology, Qin Qingwu, executive vice president, and Ji Tao, a professor of Nantong University, had in-depth exchanges with the visiting team.

　　 Wuxing technology is committed to becoming the world's leading supplier of flexible reinforced composite pipes and an invisible champion of composite materials in many high growth fields. According to Qin Qingwu, a series of innovative achievements have been made in the "key technology of braiding and composite integration of ultra large diameter high pressure resistant fracturing fluid delivery pipe".

　　 Firstly, TPU aramid EPDM inner and outer heterostructure hose was invented; The outer layer material of the blend system was invented to solve the problem that the decomposition strength of TPU decreased due to excessive extrusion pressure and temperature; The "anchoring structure" of internal and external coating polymer to fiber was constructed, and the special adhesive for aramid reinforcement was invented, which solved the common problem of difficult bonding between aramid fiber and EPDM, and the peel strength increased from 75n / 25mm to 152n / 25mm.

　　 Secondly, the damage model of fiber progressive failure in the fiber reinforced body is established, the blasting strength formula is proposed, and the safety criterion of reinforcement structure design is constructed; It has broken through the key technologies of warp tension control and transmission mode in the weaving of super large diameter aramid reinforcement; The diameter of the product is increased from 300 mm to 600 mm, and the burst pressure is increased from 6.21 MPa to 12.62 MPa.

　　 Thirdly, a complete set of knitting and compounding integrated continuous molding equipment was invented, which broke through the key technologies of braiding extrusion collaborative mechanism design and extrusion pressure closed-loop control, invented the reinforcement plasma on-line processing technology, significantly activated the aramid fiber interface, and realized the integrated continuous production of ultra-large diameter and high-pressure fracturing fluid delivery pipe. The length of single product is increased from 200m to infinite length (considering transportation, the product with diameter of 800mm is 1200m / container).

　　 The R & D and application of the project provides strong technical support for the production of unconventional oil and gas such as shale oil and gas in China, and is of great significance to ensure China's energy security.

　　 In the forum with the project completion unit, Chen Siqi focused on the public welfare projects such as "textile light" China Textile Federation science and technology award, basic research, promotion of scientific and technological achievements, and "textile light · knowledge Exhibition" activities. Li Yuhao focused on the cooperation with the textile light foundation, application of scientific and technological awards, standard formulation, etc In depth communication was conducted with the project completion unit on the requirements of industrialization development. On behalf of the foundation, Chen Siqi presented Qian Zhiguang Zhuan to the project completion unit.
