Information

In an interview with Li Lingshen, vice president of China National Textile and Apparel Council and president of China Industrial Textile Industry Association, he said that industrial textiles are still active in innovation and need to vigorously develop and fully expand the application of textile sub-fields. But looking back over the 40 years of reform and opening up, industrial textiles are also a textile sub-field with rapid development and tremendous changes. From high-performance fiber raw materials and equipment manufacturing level, to technological process innovation and application field expansion, industrial textiles can be described as "upper control of the sky, lower control of the earth, and middle air", until the end of the 13th Five-Year Plan period It is expected to account for one-third of textile fiber processing.

Industrial progress

 

Industrial textiles are an important part of my country's textile industry. With the rapid development of the industry, it has made more and more contributions to the development of the national economy and people's lives and health, and the industry has gradually become well-known inside and outside the textile industry.

In the early days of the founding of the People’s Republic of China, due to my country’s weak industrial foundation, there were few types of industrial textiles, mainly screens, industrial felts, cords, cords (threads), etc., as well as special textiles used in national defense and military industries. The Ministry of Textiles of the People's Republic of China has set up a special product department under the Department of Science and Technology, which is mainly responsible for the management and services of the textile and military industry. This has become the starting point for the development of my country's industrial textile specifications and system.

In 1984, the Ministry of Textile Industry of my country divided textile products into three areas: clothing, decoration, and industrial use. In 1985, the Ministry of Textile Industry held the first working conference on industrial textiles and divided industrial textiles into 16 categories.

In 1978, the output of cord fabrics in my country was 46,800 tons, the output of industrial fabrics was 2,695 tons, the output of industrial felts was 1,602 tons, and the output of sacks was about 320 million. Cotton is the main raw material for industrial textiles, and the proportion of chemical fiber is relatively small. For example, in the production of cord fabrics in 1978, cotton cord fabrics accounted for 77% and chemical fibers accounted for only 23%; and in 1998, 20 years later, the proportion of cord fabrics The output reached 194,000 tons, the proportion of cotton cord fabric was less than 1%, and the proportion of nylon cord fabric reached 84.9%; in 2017, the output of China cord fabric had reached 804,000 tons, and the output of nylon and polyester cord fabrics was basically Flat, cotton cord fabric has not been produced. In the past 40 years, China's cord fabric production has increased by an average annual rate of 7.37%.

In 1988, there were 1,200 enterprises in China's industrial textile industry, and fiber consumption was about 1.2 million tons, accounting for 22% of all textile fiber consumption, but the consumption of chemical fiber was only 400,000 tons, accounting for about one-third. Although the fiber consumption is large, sacks occupy a large part. In 1988, the output of sack bags in my country reached 930 million, and the fiber consumption was about 600,000 tons. If the sack factor is deducted, the fiber consumption of industrial textiles was about 530,000 tons, and the proportion of textile fiber consumption was reduced to 11%. The fiber consumption of clothing and decorative textiles accounted for 67% and 22% respectively.

In 2017, the amount of fiber consumed by industrial textiles in my country has reached 15.083 million tons, accounting for 27.8% of textile fiber processing. The proportion of chemical fiber in industrial textiles has reached about 90%. Other fibers consumed include glass fiber. The consumption of cotton, hemp and wool fibers has been very low. From 1988 to 2017, the fiber consumption of industrial textiles in my country increased by 12.24% annually, and its share in the textile industry increased by nearly 18% (the data for 1988 does not include the consumption of sacks).

In 2017, my country’s export of industrial textiles was 24.261 billion US dollars, industrial coated fabrics, non-woven fabrics, felts, tents, synthetic leather and base fabrics, packaging textiles, diapers and sanitary napkins, cord (cable) belts, wipes Cloth, industrial glass fiber products non-woven protective clothing are my country's main export products. In 2005, my country's industrial textile exports were only 5.4 billion U.S. dollars. From 2005 to 2017, my country's industrial textile exports increased by 13.3% annually. If we take Chapter 59 industrial textiles as an example, in 2000, the export value of my country's products in this chapter was only 396 million US dollars, and in 2016 it reached 6.9 billion US dollars, an average annual increase of 19.6%.

 

 

Association development

 

Since the Ministry of Textile Industry proposed that textiles be divided into three areas: clothing, decoration, and industrial textiles in the 1980s, my country's industrial textile industry has developed rapidly. In 1987, the Ministry of Textile Industry proposed a plan to establish 12 industry associations including China's nonwovens and industrial textiles; in 1994, the National Textile Industry Working Conference also proposed the establishment of 4 industrial textile associations; 1995 At the beginning of the year, the China National Textile and Apparel Council approved the establishment of the China Nonwovens and Industrial Textile Industry Association. In the following years, in accordance with the requirements of the China National Textile and Apparel Council to "build and work" International exchange and other industry work. With the rapid development of the industry in the 1990s, especially in the flood relief in 1998, the leaders of the State Council attached great importance to the promotion and application of geotextile synthetic materials in industrial textiles, and it is increasingly urgent to formally establish a national industrial textile industry association.

In 2000, the State Administration of Textile Industry proposed to the State Economic and Trade Commission and the Ministry of Civil Affairs to change its subordinate "China Textile Industry Enterprise (Group) Company Federation" to "China Industrial Textile Industry Association".

In 2001, Guojingmao Industry (2001) No. 266 and Minfa (2001) No. 252 formally approved the application of "China Textile Industry Enterprise (Group) Company Federation" to be renamed "China Industrial Textile Industry Association". In June 2002, the China Industrial Textile Industry Association held its first general meeting in Xiaoshan, Hangzhou, and Zhu Minru was elected as its chairman; in September 2006, the Association held its second general meeting in Shanghai, and Zhu Minru was re-elected as its chairman; March 2011 , The Association held its third membership meeting in Changzhou, and Li Lingshen was elected as its president; in May 2016, the Association held its fourth membership meeting in Foshan, and Li Lingshen was re-elected as its president.

From 2001 to 2010, the association continued to improve its internal management, actively develop members, and successively established spunbond nonwovens branch, spunlace nonwovens branch, interlining material branch, papermaking textile branch and strengthened the management of the branch. The association assists the government in carrying out research on the industry situation, strives for policies and measures that are beneficial to the industry, gives full play to the role of bridges and bonds between the government and enterprises, helps enterprises to expand domestic and foreign markets, and strives to do a good job in exhibitions, statistics, information, standards, and training. Provide information services for the industry. In major incidents such as the fight against SARS, the H1N1 influenza virus, the association gave full play to the advantages of industry organizations and highlighted the social responsibility of the association in serving society, enterprises and the people.

Since 2011, the association’s internal rules and regulations have become more and more perfect, and the organization has become more and more perfect. It has successively established the Filtration and Separation Textile Branch, the Geotextile Synthetic Material Branch, the Special Textile Branch, the Rope (Cable) Net Branch, the Wire Belt Branch, and the Hygiene Branch. And Maternal and Child Products Branch. Starting from the concept of “equal emphasis on broad industry and morality, and both service and gathering of people”, the association focuses on capacity improvement, performance improvement, management improvement, and cultural improvement. By transforming service models and extending service chains, it is guiding the healthy and orderly development of the industry, Promoting industrial transformation and upgrading, accelerating the cultivation of collaborative innovation in the industry, deepening international exchanges and cooperation, creating public service platforms, using relevant national industrial policies to promote the coordinated development of large and small enterprises, improving industry standardization work, and deep integration of application fields. The association was rated as a 4A-level association by the Ministry of Civil Affairs in 2012, and was rated as a national advanced social organization by the Ministry of Civil Affairs in 2015.

 

 

Non-woven

 

Nonwovens are an important field of industrial textiles. In terms of non-woven fabrics, my country first began to study non-woven fabric technology and equipment in 1958 by the Shanghai Institute of Textile Science. In 1966, the first non-woven fabric factory was put into production, using web stitching and saturated impregnation bonding. Production of non-woven fabrics. In 1986, there were about 300 companies in my country, with an output of 180 million square meters, equivalent to a weight of about 54,000 tons. At that time, the global output was about 1 million tons. Interestingly, of the 300 nonwovens companies, only 18% of them are in the textile system, while 82% of the companies are in the light industry, building materials, petrochemical, handicraft and commercial systems, reflecting the industrial textile industry from one side. The characteristics of cross-field and cross-industry. From the process point of view, thermal bonding and chemical fiber bonding are the mainstream technologies, accounting for more than 70%. At present, the mainstream spunbonding process is still in the equipment debugging stage. The spunlace process has not been introduced in China, and the application is sprayed cotton , Interlining, etc. The current medical and health field with the largest application volume is still blank.

By 1997, the number of nonwoven production lines in my country had exceeded 1,000, with a production capacity of 540,000 tons and an actual output of 290,000 tons. Compared with 1986, the output had increased by 437%, with an average annual growth rate of 16.5%. In 2017, the output of China's nonwovens was 5.643 million tons, the proportion of spunbonded nonwovens was nearly 50%, and the proportion of thermal bonding and chemical bonding was less than 13%. From 2000 to 2017, my country’s export volume of non-woven fabrics increased from 34,000 tons to 894,000 tons, and the export volume increased from US$94 million to US$2.61 billion, with an average annual growth rate of 21.21% and 21.59%, respectively. The share in global trade Increased from 2.1% to 17.6% in 2016.

The industrial textile industry is widely used in medical and health, environmental protection, geotechnical construction, transportation, emergency safety, aerospace and other fields. It has high technical content, wide application scope, and large market potential. It is a component of strategic new materials and is a global The focus of competition in the textile field. Since the reform and opening up in 1978, the rapid development of the national economy has not only provided the material basis for the development of the industry’s science and technology, but has also continuously put forward new needs and directions for the industry’s technological innovation work. The issuance and implementation of the scientific and technological plan provides guidance and support for the technological progress of the industry. Enterprises and scientific research institutes in the industrial textile industry have actively adopted independent innovation, integrated innovation, introduction, absorption and re-innovation, and achieved a series of results and rapid promotion and application. Continuous support has promoted the overall development of the industry.

 

Industry national honors are increasing

 

Since the reform and opening up, the industry's scientific and technological work has achieved many major successes. According to statistics, from 1978 to 2017, more than 40 scientific and technological achievements in the industry and related fields have won the National Science and Technology Progress Award or the Technology Invention Award. In the early stage of reform and opening up, the industrial textile industry was in its infancy, and the scientific and technological achievements of the industry were mainly concentrated in the use of production and processing equipment and innovative applications. For example, in 1979, two industry-related cotton grabber projects won the third and fourth prizes of the National Technical Invention Award respectively. After entering the 1980s, some industrial textile products that meet the needs of people’s lives and basic industrial production have achieved breakthroughs, such as "soluble hemostatic gauze", "water- and oil-proof and breathable coated cloth", needle-punched paper blanket, high-grade synthetic leather, Antarctic Scientific research cold-proof clothing and other projects have won the National Technology Invention or Science and Technology Progress Award; at the same time, the industry has paid attention to some international cutting-edge technologies and product development trends, and carried out in artificial blood vessels, electrospinning technology, hollow fibers and ultrafilters. Part of the exploration and research and achieved certain results, respectively won the National Technology Invention or Science and Technology Progress Award; fiber raw materials and mechanical equipment are the foundation and important driving force for the rapid development of the industrial textile industry. At the end of the 20th century, with breakthroughs in key technologies and products in the chemical fiber and textile machinery fields such as water-soluble fibers, high-strength and high-modulus vinylon, high-yield carding machines, and needle punching machines, the industrial textile industry has made great achievements in product performance and application fields. Significant improvement and expansion.

After entering the 21st century, the industrial textile industry has better met the application needs of industrial production, national defense and military industry, people’s life, environmental protection and other fields. The industry has even more embodied the characteristics of high technology content, wide application fields and unlimited substitution. Achievements are more recognized and valued, and the level and weight of national awards won are increasing. In 2017, Dalian University of Technology's "High-quality and efficient processing technology and equipment for high-performance carbon fiber composite components" won the first prize of the National Technology Invention Award; Zhongfu Shenying Carbon Fiber Co., Ltd. "Dry Jet Wet Spinning 1000-ton high-strength/100-ton "Key Technologies and Applications for the Industrialization of Grade Medium Model Carbon Fiber" won the first prize of National Science and Technology Progress Award.

 

Spunbond meltblown technology leaps three stages into the world's advanced

 

On January 18, 1987, the spunbond production line of Reifenhäuser from Germany, introduced by the Guangzhou Second Synthetic Fiber Factory, was put into operation, which ended the history of China without spunbond nonwovens equipment and products. The production line has a width of 2.4 meters. , The production capacity is 1,000 tons/year, and the whole board, negative pressure drafting process is adopted. On July 11, 1992, the first domestic spunbonded nonwovens production line was put into trial run at Jinzhou Nonwovens Factory. The line adopted a multi-board, small slit drafting method with a width of 2.5 meters. The production capacity is 1,000 tons/year. In July 1993, Jiangyin Jinfeng Special Textile Co., Ltd. first introduced the 2.4-meter-wide meltblown production line of Reifenhäuser from Germany, and Tianjin Teda Clean Material Co., Ltd. and Anhui Aohong Ultrafine Filter Material Co., Ltd. introduced Accurate from the United States. (Accurate) The company's 1.6-meter meltblown equipment, these continuous coil production lines have changed the history of our country that only intermittent processes can produce meltblown sheets. In May 1996, Beijing Baosite Company successfully developed a domestically-made meltblown die head with a width of 1 meter, realizing the domestically-made meltblown nonwoven production line wide continuous coil production.

For more than 30 years, China’s spunbond meltblown industry has experienced three stages of initial construction, rapid growth, and adjustment and upgrading through digestion and absorption, independent innovation, product development and market expansion. At present, China’s spunbond meltblown industry has a complete range of products and a wide range of applications. , Equipment manufacturing has also made considerable progress. Some technologies and product performances are close to or even surpassing the world’s advanced level. Applicable raw materials include polypropylene, polyethylene, polyester, polyamide, polylactic acid and polyphenylene sulfide. The production process includes thermal Rolling, acupuncture, spunlace, meltblown, SMS, multi-die head combination, two-component composite and other categories have not only basically met domestic demand, but also been successfully exported to many countries around the world.

 

The rapid development of spunlace technology has become the largest production and sales base in Asia

 

In 1995, Hainan Xinlong Company introduced a European spunlace production line with a width of 2.5 meters; in 1996, Ningbo Yuhao Company successfully installed a Taiwanese spunlace production line; in 1998, Changshu Feilong Company developed the first domestic flat-net spunlace Production line: In 2001, Hebei Donglun Industrial Co., Ltd. built the first domestically-made rotary drum spunlace production line. The production line equipment was provided by Zhengfangji with a width of 2.5 meters. For more than 20 years, my country's spunlace nonwoven industry has developed rapidly. my country has become the largest spunlace nonwoven production and supply base in Asia, and the largest OEM manufacturer of wet wipes and medical products. In recent years, the spunlace nonwovens industry has gradually transformed into product structure adjustments according to the law of market demand, and the industrial technology routes and product categories have shown a trend of differentiation. At present, there are three main categories of spunlace nonwoven products. The first category is a wide range of medical and health materials, mainly dry/wet wipes, surgical gowns and valances, medical accessories, and mask substrates; second The main category is industrial materials, mainly ordinary synthetic leather base fabrics, microfiber leather base fabrics, automotive composite base fabrics, etc.; the third category is building decoration materials, mainly decorative wall cloth, curtain cloth, clothing interlining, etc. .

 

Acupuncture technology started late and the market matures

 

my country's needle punching non-woven technology started relatively late. In the 1980s, Shanghai Textile Machinery Research Institute introduced and designed a 112 type needle punching machine with a width of 1120 mm and a frequency of 120 times per minute. Shanghai Textile Machinery Research Institute commissioned Jiangsu Changshu Renyang Agricultural Machinery Factory to process and manufacture prototypes. Renyang Agricultural Machinery Factory has the manufacturing technology of acupuncture machines, and gradually formed my country's earliest acupuncture machine production base in Renyang, Changshu. At the end of the 20th century, my country's needlepunching nonwovens market gradually matured, technology progressed rapidly, and competition became increasingly fierce. 250 and 360 type wide needle punching machines began to appear. The needle punching frequency reached 600 times per minute, and the variety of needle punching machines increased. To pile needle punching machine, jacquard needle punching machine, etc. At present, my country's acupuncture machine can process products with a width of 8,500mm and acupuncture frequency of 1,800 times per minute. There is still a gap between the overall level and the international leading technology.
