When you think of textiles, not many of us think of the technical factor.

Technical textile includes material that is mainly used for its technical properties and superior performance. A report by Transparency Market Research predicts that the demand for technical textile will increase to US$ 160.38 billion by the end of 2018. The report also says that technical textile will maintain a Compound Annual Growth Rate (CAGR) of 3.3 per cent in terms of volumes, taking the global demand to 30.71 million tons by the end of 2018.

Pushing the development of technical textile is the escalating demand for nonwovens. According to a new study by Grand View Research, Inc, the global nonwoven fabric market is expected to reach US$ 42.1 billion by 2020. The sector also owes its growth to accelerated demand for technical textile in Asian giants like China and India. The Chinese economy and the sheer bulk of the population are some of the factors that have been supporting swift development of technical textile, especially nonwovens.

A success story

Even as the global consumption of technical textile rises, it is eastern Asia that alone accounts for one-fifth of total technical textile consumption. Globally, United States consumes 23 per cent of total technical textile. A close second is Western Europe at 22 per cent. China gobbles up 13 per cent.

According to China Nonwovens and Industrial Textile Association, domestic consumption of technical textile in China is forecast to reach US$ 46.5 billion by the end of 2015. Technical textile exports and imports are projected to stand at US$ 23.2 billion and US$ 4.2 billion, respectively. The technical textile industries in China rely on Taiwan, Japan, South Korea, United States of America and Germany for export of plastic-coated fabric, nonwovens, industrial fibreglass products, medical and health care textile.

The major technical textile sectors in China include filtration and separation that is growing at an average annual rate of 13 per cent followed by the civil engineering sector at 12.5 per cent. The transportation, medical and healthcare sector are each growing at 12 per cent. Structural modification stands at 11 per cent.

Prompting the growth

The growing elderly population in China aids vast demand for adult hygiene products and with China relaxing its one-child policy, the baby boom is once again likely to result in high demand for diapers, boosting the technical textile sector. Construction spending in China is greater than ever, and this is also expected to have an encouraging influence on the growth of the market.

China’s automobile sector is on top gear. The burgeoning automobile market in China has led to the rapid increase in demand for airbags. In 2013, demand in the domestic market for airbag fabric was 28.94 million meters. With laws taking safety issues seriously, demand for automotive airbags will gradually rise and it is expected to be 43.86 million meters by 2018.

Technical textile industry is new and growing sector in India. It generates good revenue for the country. This industry is rich with many natural and synthetic fibres. All these fibres are useful in different ways. Synthetic fibres are made from doing some special chemical processes on natural fibres or obtained directly from chemicals. These fibres have greater qualities than simple man made fibres so it is widely used in the industry not only for the apparel use but is used in other various applications also. Some synthetic fibres are Acetate, Rayon, Nylon, Polyester, Acrylic, Olefin, PLA and Modacrylic and some fibres with special properties are Saran, Vinalon, Vinyon, Spandex, Modal, Sulphar, Twaron, Kevlar, Nomex, PBI, Loycell, M5, Zylon, Dyneema/Spectra, Vectran, Glass fibre, Metalic fibre and Acrolynite. In this article we are covering the major five fibres used in the technical textile industry. The properties, applications and leading manufacturers of these fibres are also covered. These fibres are listed below.

1. Polyethylene
2. Polyester
3. Nylon
4. Carbon
5. Polypropylene

Introduction:

Polyethylene is a polymer. Many no. of ethylene monomers join with each in the synthesis of polyethylene polymer. Polyethylene is obtained by the polymerization of ethane. Cationic coordination polymerization, anionic addition polymerization, radical polymerization and ion polymerization are the different methods by which polyethylene can be produced. Every method gives different types of polyethylene. Mechanical properties of Polyethylene depend on the molecular weight, crystal grouping and branching. Some properties are as follows:

Properties:

• Very good ultra violet resistance
• Excellent electrical and chemical resistance
• Low moisture absorption level
• Very good abrasion resistance
• Low specific gravity
• Higher energy is needed to break because of specific modulus and high specific strength

Application of polyethylene

• Medical implants
• Cable and marine ropes
• Sail cloth
• Composites like Pressure vessel boat hulls, sports equipment, impact shields
• Fish netting
• Concrete reinforcement
• Protective clothing
• Can be used in radar protective cover because of its low dielectric constant
• Can be used as a lining material of a pond which collects evaporation of water and containment from industrial plants
• Useful in geotextile applications

Technical textiles are technologies of the future for several sectors of strategic importance to our society: transport, defense, health, construction. Technical textiles are considered an essential component of tomorrow’s leading-edge products.

The program of the NSERC Industrial Research Chair in Innovative Technical Textiles focusses on three key the matics :

• Sustainable development, sustainable construction, re-use,
• Protection, safety and comfort, and toxicity, and
• Smart textiles.

The Chair head multi-partner technology watch projects and contract projects. Through multidisciplinary teams, the projects foster innovation and other activities that lead to productivity gains and increased competitiveness.

They commercialize patented products developed in partnership with CTT GROUP, a key partner of the Chair. As the founding members of the Chair, they rely on innovation as their corporate development strategy in a demanding business climate, collaborating along the entire value chain.

The involvement of the ÉCOLE DE TECHNOLOGIE SUPÉRIEURE, and particularly its Research Chair on Materials and Protective Equipment used in Occupational Health and Safety, will promote mutually beneficial networking between the two levels of post-secondary education in shared areas of research.

New areas of applications of cyclodextrins with technical textiles are possible. The ability of cyclodextrins to form inclusion complexes can be used, e.g., to remove malodor from technical textile materials. The permanent fixation of cyclodextrins offers new textileswith interesting properties. Thus the formation of body odor is reduced by the complexation of the organic compounds of sweat. The release of perfumes from cyclodextrins is possible by the use of technical textiles with fixed cyclodextrins. Pharmaceutical compounds are also set free in contact with the skin. Last but not least the analysis of the different compounds of the human sweat complexed by the cyclodextrins offers new possibilities in medical diagnostics.

Uses of cyclodextrins in connection with technical textiles

Two fundamental possibilities have to be distinguished:

(1)There are no chemical or physical interactions between cyclodextrin and the textile materials.

In this case cyclodextrins or their complexes are used to positively influence the quality of ues. It is known that cyclodextrins from complexes with perfumes or fragrances which can be stored over a long period without loss of these substances. The complexes organic substances are only set free in contact with moisture. Thus it is possible to add a fresh smell in a drier to just washed laundry using cyclodextrins complexes. The fragrance complexes inside the drier. Cyclodextrins complexes with fragrances and perfumes are stable over a long period and may therefore also be used in washing powder and other products for the cleaning or care of technical textiles.

On the other hand unpleasant odours of technical textiles can be removed by the complexation with cyclodextrins. Spraying such a textile with a solution of cyclodextrins results in complex formation with the substances responsible for the unpleasant odour. No interactions between these complexes and the textile materials take place. As a result the complex is removed from the surface by mechanical stress. For example, during the cleaning of carpets the solid complex is removed together with dirt particles. Afterwards the textile material is completely odourless again because the unpleasant odour was removed not masked. Cyclodextrins or their complexes remaining are very soluble in water and they are at least removed from the material with the next washing.

(2)There is permanent fixation of cyclodextrin on the fibre surface.

Another possible use of cyclodextrins results from the permanent fixation on different polymeric materials. Cyclodextrin derivatives with a reactive group, the monochlorotriazinyl group are able to react with the hydroxyl groups of cellulosic fibres like reactive dyes. Permanent fixation on fibres made from polyester is only possible with cyclodextrin derivatives with long alkyl chains or other hydrophobic groups. Comparable with disperse dyeing, the hydrophobic part of the substituted cyclodextrins migrates into the fibre above the glass transition temperature.
