5) Development Center of Automotive Textile Materials 

Various materials are used in auto manufacturing, metal material, rubber material, and textile material, a material the application of which is on the rise. Its serving as both decoration and reinforcement has developed very fast. Statistics show that automotive textile material accounts for 1/3 of all the industrial textiles and in recent years, it has reached the highest percentage, 35% of industrial textiles in Western Europe.

With development of auto industry, the decorative material of interior automobile has experienced three changes. In the 1950s, polyvinyl chloride (PVC) was widely used as the   interior automotive decoration. Later, besides the traditional woven fabric, the fabric mixed by PVC fiber and nylon was used in the seat of the Ford car but proved unpopular. However, a teasel cloth for automobile made by the French people was immensely popular and the Company Volvo received a great deal of benefits from producing polyamide and polyester fabric. Since the 1970s, textiles were used as decorative materials of interior automobile instead of PVC abroad. By the 1980s, with reduction of PVC, some parts of automotive decoration were replaced entirely by the textile. In the 1990s, textiles occupied an important position in the interior automotive decoration. In 1993, the textile of interior automotive decoration in the world took up 371 million square meters. And statistics show that in America, it covers about 220 million square meters per year; in Western Europe, 100 million. The general tendency is that the interior automotive textile is still growing at a rate of 2% per year.

Development of the auto industry provides a developing opportunity for the textile industry in China. However, the automotive textile in our country is in a seriously short supply and most of it depends on imports because our industry of automotive decorative textile started late. In the past, the basic material of the interior automotive decoration was artificial leather and there was no professional manufacturer of automotive carpet in China for a long time. Until the late of the 1980s, there emerged the first fabric manufacturer of car seats. Up to now, there have been dozens of manufacturers producing fabrics of interior automobile. Nowadays, textiles account for over 50% of interior automotive fabrics. Textile fabric has replaced artificial leather as the basic interior decorative fabric in top-grade automobile while in low and middle-grade automobiles it has been adopted gradually. It is predicted that the demand for the textile of interior automotive decorative fabric will have reached 30,000 ton per year and 100,000 ton by 2010.

Decorative Textile for Interior Automobile(DTIA) is a high-technique production with strict demands for its stuff and complicated processing skills. In countries with advanced auto industry like the USA, Germany and Japan, the research of DTIA has been drilled deeper while the research and production in our country are just on the threshold. In recent years, with development of the auto industry, many enterprises in our country have developed this kind of textiles and achieved a certain progress. However, we still have a long way to go.


6) Textile Technology Development Centre for Building Materials

Since Ninth Five-Year Plan, the building material industry has been regarded as one of the four pillar industries of our national economy.

Urbanization is a major step for the economic development of our country. Since dwelling places are in great need, there will be lots of transformation work, including rural housing and public buildings, which constitutes a big market.

Investment in capital construction helps encourage not only the present but also the long-term development of our national economy. According to the economic plan, building material industry is of great significance in developing national economy. The goal of construction industry is to develop “intelligent structures”. According to the Eighth Five-Year Plan intelligent structure is light-duty, energy-saving and safe. Intelligent structure also demands increasingly comfortable environment of living and work, which is embodiment of the sustainable development in buildings.

This development trend of construction industry involves application of advanced technology in traditional building materials, which calls for the multi-disciplinary research, study of textile included. Donghua University thus shall broaden her research field to promote innovation of science and technology in textile industry, which is also necessary for the development of national economy. In such a background, we deliberated with the Science and Technology Committee of Shanghai Municipal Construction and Management Commission and its companies on the development of new building materials around 1998. Finally we initially confirmed that the following aspects are pressed for the participation of textile technology.
  ①  materials for wall
  ②  cement mortar
  ③  waterproof materials
  ④  matrixes for the greening of buildings
  ⑤  materials for cover
  Though building material industry covers wide fields, research work is still very arduous. Research fellows in textile technology should actively break the former barrier between different regions to enter this field. Since many foreign firms have already entered Chinese market, competition in this field is intense. Teachers in our universities are expected to take an active part in research work and development of this field, which is not only necessary for development of the new building material field but also for development of textile study itself.


7) Technological Development Center of Agricultural Textile

Agricultural textile, a new industrial product, is an important material to change backward agriculture and extensive operation mode, whose application constitutes a part of great importance in agricultural modernization. Textiles are widely used in agriculture in some developed countries.

At present, foreign agricultural textiles mainly include textile materials for agricultural covering, substrate materials in plant growth, greenhouses, farmland and water conservation and other sectors. Varieties and quantities of agricultural textiles are on the rise in the developed countries. There should be a high demand in China, a large agricultural country with development of agricultural science and technology. However, the fact is that a considerable disparity exists between marketing share and ideal potential market.

In 1993, the consumption of agricultural textile fibers in China was 1.5 million tons. And it’s predicted that the demand of agricultural textiles will be over 8-10 million tons till 2000. It can be used to improve the level of agricultural production, but meanwhile, it’ll become a chance and a challenge to the textile industry. Undoubtedly, it’s of great significance to the research, development, production and application of agriculture and textile industries by means of combining with the growth of crops.

Here three main agricultural textiles are introduced as follows:                     
  Ⅰ. Agricultural Covering Materials
  Agricultural covering materials consist of films and fabrics. Films have been widely used in foreign countries in the sixties and seventies. In late seventies, a new-generation agricultural covering materials with non-woven was used in two thermal screen of greenhouses for the early post-cultivation.
  Ⅱ.Textiles in Greenhouses
  As a kind of agricultural facility, greenhouse plays an important role in the modern agriculture at home and abroad. It significantly improves people’s life and provides them with fresh vegetables and fruits all the year round.
  Temperature and climate inside the greenhouse should maintain relatively constant at all seasons. Thus materials for lowering temperature, storing energy and keeping warm are needed.
  Ⅲ.Textiles in Flower Industry
  Since clean potted flowers with a long flowering period and easy management replace fresh flowers, flower industry constitutes an important part in urban agriculture. Apart from planting, cultivation, fertilization and management technology, a large number of textiles are to be consumed.
  The main varieties go as follows:
  ⅰ. A large number of textile materials are needed in substrate cultivation of potted flowers as fiber materials can reinforce the root system, water and fertilizer and help breathe.
  ⅱ. Before entering a family, we should firstly consider its beautifying effect. The layer of non-woven cloth covered on the surface of substrate materials can prevent water evaporation and pests, and keep warm. What’s more, printings and colors on the non-woven fabrics add the beauty.
  ⅲ. The traditional clayey and plastic flower pots only fit the long-term use and pose great pollution to cities. Therefore, most foreign countries turn to flower pots which are composed of degradable fibers, such as wood fiber, straw fiber, and appropriate adhesive. The permeability of pots, degradation of life and other properties are controlled through adjusting adhesives.
  ⅳ. At present, foreign countries largely adopt the special non-woven cloth to package the fresh flowers. This kind of non-woven cloth is not beautiful, but also helps keep flowers fresh.


8) Technology Development Center of Geosynthetics 

1. Geosynthetics has been regarded as the fourth largest building material (after the three main materials: steel, cement and timber) in the world, the characteristics of which go as follows:
(1) Different Constituents
  Steel and cement are inorganic substances, chemically combining elements like Fe, C, Ca, Mg, Si, O by metallic and electrovalent bond, while Geosynthetics is an organic one, chemically combining elements like C、H、O、N by covalent bond. Thus it is characterized by thermo-optical instability, heat-resistance, inflammability, etc.
(2) Different Mechanical Properties
  Compared with that of steel and cement, strength and modulus of Geosynthetics are low. Geosynthetics, with the properties of malleableness, flexibility and impact-resistance, is especially suitable for building projects of great deformation, such as projects in soft soil, marsh, frozen soil areas, etc.
(3) Light Weight
  Specific gravity of Geosynthetics is smaller than that of steel and cement. (Geosynthetics: 0.88~1.6t/cu. cm.; Steel: 7.8g/cu.cm.; Cement: 2.7g/cu.cm.)
(4) Different Processing Methods

The technology of pyrolytic smelting is adopted to process steel and the technology of high temperature calcination is chose for cement. But in Geosynthetics, geotextile is woven with chemical fibers (such as PA, PP, PET, etc.), needle-punched geotextile is needled with staple fibers (such as PP PET, etc), and the basic chemical fiber is made by melt spinning. In a broad sense, geotextile, a kind of building materials, is much better than traditional textile for clothes. Apart from cohesive soil, cohesionless soil and other peculiar soils are involved in the geosynthetics which is beyond the scope of the common soil and stretch to the study of tailing, ocean soil, polluted soil, etc. Thanks to interdisciplinary, the application of Geosynthetics will be expanded to a broader material space.

2. Simple in application as it is, Geosynthetics is multi-functional and can bring significantly economic benefits. In many projects such as projects of construction, water conservancy etc, no material can be as useful as Geosynthetics that has so many functions to solve the problems of those projects. Generally speaking, Geosynthetics can help consolidate subsoil, prevent erosion, drain and stabilize slopes and so on. With the development of normalization, standardization and legalization, application of Geosynthetics on a large scale will be bound to happen.

3. The output of major raw materials of Geosynthetics has increased from 2,900,000 tons to 4,000,000 tons per year during the Ninth Five-Year Plan period. Proportion of differential and functional fibers has been raised from 16% to 25% in particular. Chemical fiber industry will lay solid foundation for the development, application and spread of Geosynthetics.

4. China’s textile industry is now under structural adjustment. The proportion of the three main applications (clothing, decoration and industry) has changed from 74:17:9 to 60:25:15. In recent three years, the cost of the infrastructure construction in China is up to RMB750 billion, 1~2% of which is spent in Geosynthetics by foreign standard (i.e. RMB7.5~15billion).  It is predicted that geotextile’s development will become a new breakthrough and it will turn into a new economic growth point in the textile sector of China.

5. Geosynthetics, a comprehensively interdisciplinary subject and a new product of modern disciplines, involves study of textile, plastic, petrochemical, soil, water conservancy, geotechnical construction, etc. The development of Geosynthetics will raise the whole level of infrastructure construction. As technology is the first productive force, we must value technical reformation and innovation. “Innovation sustains the progress of a nation and is an inexhaustible motive force for the prosperity of a country. A nation without innovative capability is hard to stand among the nations of the world.” Jiang Zemin pointed out.

11) Technology Development Center of Textile Material for Biomedicine

 The medical textile has come into being for quite a long time. It is based on fiber and fabric, specializing in medical application. It is a novel and unique part in the field of textile industry.

(1) Categories of medical textile
  According to the functions and applications, the medical textile can be divided into general medical textile and high-functional medical textile. The former involves medical care cloth, cloth for patients and wards, isolated clothes for medical care personnel, and cloth for operating room, etc. The latter is made by high-tech fabric material, which holds various functions, including the following four categories:
  --health care: sterilization and deodorization for clothes, shoes and hats, etc.
  --medical treatment: the textile for homeostasis and itch-free, comfort, and anti-viral   ones
  --imitation device: artificial blood vessel, artificial airway, artificial esophagus and artificial kidney
  --protection type: various kinds of radiation proof clothes (x-ray proof, neutron proof, electromagnetic radiation proof)
      It can also be categorized as follows:
          Non-graft material-- for external use, such as wound dressing, bandage and plaster
          Transplant material--used as suture for the wound mending or replacement, blood vessel graft, artificial joint
          Artificial organ--kidney, liver, lung
          Sanitary health care product--bedding, clothes, surgical clothes, fabric, and the device for the separation, filter, gathering and     condensation for plasma

(2) The medical field and related products of medical textile

Fibers used in medical treatments and operations can be divided into natural fiber and synthetic fiber, biodegradable fiber and non-biodegradable fiber, which should have the quality of non-toxicity, non-allergy, non-carcinogenicity and no physical or chemical changes during disinfection. Cotton, silk and rayon of viscose, the widest use of natural fiber, are used as non-graft material and sanitary health care product. The common chemical fiber includes polyester, polyamide, PTFE, polypropylene, carbon fiber and glass fiber.

Compared to the traditional pure cotton woven medical textile, the medical non-woven fabric holds the qualities of high filter capacity to bacteria and dust, low infection rate in operation, convenient sterilization and easy composition to other materials.

In recent years, the R & D of new anti-bacterial textile are taking process in many countries, including the research of new fiber, new polymer, new processing technology, and many new applications of sanitary health care, which can kill the bacteria more efficiently.

For example, France has recently adopted the grafting technology into medical textile, which is called “medical textile”. Dupont Dacron uses fiber to produce pillows and quilts, which are called “the breathing bedding” because of its advantages of mould proof and allergy proof. ANTRON carpet yarn is a kind of special fiber, holding the features of anti-static, high resistance to flame, high color fastness and smooth surface, etc.

In conclusion, the medical textile is based on material and fabric. Its rapid development responds to the medical need of people and the research of new textile materials. Medical textile is a quite potential and promising field.
