Introduction
The new technologies are now evolving expressively. One of the great evolutions is the creation of nanotechnology which was predicted as the second industrial evolution in the world. The created fresh properties not only improve the human’s quality of living, little amount material utilisation will help saving environment and energy.
Based on this viewpoint for nanotechnology, thorough studies have been commenced across industries and disciplines globally. And from this, textiles industry is not exception and nano textile products have already materialized in the marketplace and the quantity of by-products or nano-claimed products is increasing dramatically.
Discussion
UK clothing and textile market was once a foundation of the UK economy but since the production work has been outsourced to other countries most of production houses and factories in UK have been closed. In previous years, the prices of clothing and textile products are falling due to outsourcing in the developing countries and generating cheaper supplies. The technology and innovation in the industry also affects its development. However, the most important issue in clothing and textile market is the Republic of China, after the end of world trade agreement in 2005, China has flooded the UK and US markets with cheap products. This has resulted in a drop in employment in textile and leather industries from half a million in 1980 to less then 140,000 in 2005. According to Business Monitor PA1003 there were 12,030 VAT-registered companies involved in clothes retailing in the UK in 2003, where the vast majority of clothing retailers (89.3%) employed fewer than ten people in 2003, while 72.1% employ fewer than five. Those employing 50 or more accounted for just 1.9% of the total (Key Note, 2006). Despite of this, the key notes in the UK reveals that clothing and footwear market was worth an estimated £44.45bn in 2005, which accounted for less than 6% of total consumer expenditure (Key Notes 2006) and as of 2009 the industry was continuously growing with regards to the help and current evolution in technology.
The UK clothing and textile industry is growing strong in fashion and design and with regards to the development of technology in this industry such as the integration of nanotechnology in their manufacturing procedures, the costs of production are falling. However the UK clothing industry has lower productivity than leading European competitors and is increasingly being threatened by low-cost foreign competitors who are eroding the profit margins. Also downturn in the economy is a major threat to the clothing industry as it could cause men, in particular, to cut back on overall spending in this sector.
It is now a widely held view that the world economy has entered a much more complex phase where individual national economies have become inextricably linked. In this new world economy, resources and markets have ceased to have the indelible national identity of the past. Restricted resources and markets that were once legally isolated have become much more accessible to enterprises that have acquired a global strategic vision. To the more visionary global enterprises, the world is but a borderless environment with homogeneous consumers who have developed an unforgiving taste for the most sophisticated and high-quality products. In response to the needs of these global consumers, the enterprises have developed global products. How such homogenised consumers are served, however, is a question of the strategic orientation of the enterprises and their ability to exploit the ever-evolving global economic environment. One of the strategic orientations that has been practiced in textile industry was the integration of nanotechnology.
Nanotechnology is a sub-classification of technology in colloidal science, biology, physics, chemistry and other scientific fields. As a field of applied science, it focuses on the design, synthesis, characterization and application of materials and devices on the nanoscale. It is also used as an umbrella term to describe emerging or novel technological developments associated with microscopic dimensions (Allhoff F & Lin P (eds.), 2008).
In its broader term, nanotechnology includes the many techniques used to create structures at a size scale below 100 nanometers or 100 billionths of a meter. This includes those used in semiconductor fabrication such as deep ultraviolet lithography, electron beam lithography, focused ion beam machining, nano-imprint lithography, atomic layer deposition and molecular vapor deposition, those used for fabrication of nano-wires and those used at the molecular self-assembly techniques such as those employing di-block copolymers (Allhoff F & Lin P (eds.), 2008).
Nanotechnology uses two main approaches in its operation processes. First is the bottom-up approach where materials and devices are built up atom by atom. Second is the top-down approach where they are synthesized or constructed by removing existing materials from larger entities. The vastly increased ratio of surface area to volume present in many nanoscale materials is a unique aspect of this technology opening new possibilities in surface-based science such as catalysis. However, this catalytic activity also opens potential risks in their interaction with biomaterials (Allhoff F & Lin P (eds.), 2008).
According to Port (2002), nanotechnology is the new Industrial Revolution. It leaves virtually no business untouched or unscathed. The ability to create materials from building blocks the size of a virus unleashes unprecedented capabilities. Autos and airplanes, chemicals and plastics, computers and chips, cosmetics and drugs and plenty of the other industries face upheavals because of this technology (Port, 2002). Basically, the prefix 'nano' is used to indicate the billionth part or 109th part of a quantity. Sometimes, nanotechnology was also known as molecular manufacturing which is a branch of engineering that is related in manufacturing and designing of extremely small electronic circuits and mechanical devices built at the molecular level of matter. Actually, this type of technology has enabled researchers and scientist to gain precise control over matter at the atomic and molecular level. A scientist had once said that some of the problems of chemistry and biology could be simplified if we could work at the atomic level and actually see what we are doing.
This technology promises humans’ ways of making systems that are smaller, lighter, stronger and more efficient but cheaper to produce. Some of these current products include chemicals produced with microscopic catalytic particles, sun lotions with invisibly small zinc-oxide flakes to shield against ultraviolet rays, emulsifiers that keep paint from separating and coatings that make eyeglass lenses more scratch resistant or extend the life of industrial tools. More alluring products can be found in nanotechnology company laboratories but many need a year or two to reach the market because new manufacturing systems also must be developed (Port, 2002).
As explained by Professor Mark Welland, head of the University of Cambridge Nanoscale Science Laboratory, “Nanotechnology is not a technology in its own right. It is an enabling technology, so it will appear in many different products”. Welland added that such technology is already appearing in flash memory, computer chips and will increasingly be an enabling technology in other products like coatings and new types of sensors (as cited in Twist, 2004).
On the other hand, because of the very precise way in which their atoms are arranged, nano-materials exploit unusual electrical, optical and other properties. This means that fabrics could change colour electronically. Thus, exposing an army uniform to ultra-violet light could activate changes without undressing. But in medicine, nanotechnology offers the most remarkable advances (Twist, 2004).
With regards to the development of the Textile industry, the integration of the nanotechnology is a breakthrough (David R. 2009). As the extent of materials to which nanotechnology can be applied is increasing. Moreover, the opportunities for application are widening. Aside from the textile industry, nanotechnology has potential applications in computers (nano chips), aerospace (launch vehicles, nanotubes), colorants, and biotechnology and in varies other fields. Nanotechnology is without doubt, the technology of the future. In the field of textiles, nanotechnology has been employed in the synthesis of quantum dot (semiconductor nanocrystals) (David R. 2009). David R. (2009) stressed that dye molecules are used to cloud fibres. In nanocrystals, the colour changes with increase in particle size. It is thus possible to create different size particles from a single material having different optical properties that cover the entire visible region. Moreover, in textile manufacturing, the idea in which colour is imparted to fabrics through a process called subtractive colours mixing and later on many of the colours produced in nature are a result of interaction of light with matter, by interference or diffraction phenomenon is actually can be applied to textile dyes to obtain pure and bright hues which is known as Nanocrystals as colourants (David R. 2009). Finishing of textiles and fibre manufacturing are areas where nanotechnology has great potential for application. The lotus effect finish mentioned earlier is an example. Moreover, it is estimated that nanotechnology in textiles will be billion dollar business in the next few years.
In addition to the development of nanotechnology in the textile industry around the globe, the review of the products exported by USA to China in January-April 2005 shows that the top three textiles and apparel products in terms of percentage enhance in exports were Non-woven fabrics, tire cords and tire fabrics and textile/fabric finishing mills products (FICCI, 2005). These products are not seen in the items that India has provided. The entrance into an innovative application domain of industrial textiles, homes furnishings, nano-textiles and others becomes imperative if the market are to grow 5-6% of global market a these regions are projected to significantly grow. On one hand, innovation includes synthetic textiles which compose of 50% of the global textile market. However, in Indian synthetic industry, this aspect is not well entrenched. In this regard, the Technology Upgradation Fund of the Indian government is being utilised to motivate investment of small scale business in new processes.
Accordingly, textile and apparel policy has come along ways in decreasing uncertainties for the industry. Such policies are driven by global competition and also by the international trade provisions. However, in the Textile industry, few areas of policy weakness has been noted, which include the labour context, power availability and the customer clearance, credit for large scale investment, shipment operations from ports and quality, which are necessary for upgrading the technology, and enhancement of the manpower of the textile and apparel industry (Cover story 2002).
Moreover, the Massachusetts Institute of technology (MIT) in USA initiated a plan using nanotechnology to develop chameleon-lick uniforms and materials that could help protect soldiers against detection, threats, bullets and chemical agents, monitor their life support systems and even heal those who are wounded (Uldrich J 2002). Basically, it is a textile, which is woven together bringing lots of dissimilar kinds of potentials together in a single garment. It would offer chemical protection, ballistic protection, sensing, it could vary from a soft fabric to a hard kind of shell for defense.
Basically, it is designed to automatically generate splints and cast through so-called Ferro fluids filling the hollow Faber of the fabric. These will permit the suit to be converted from a flexible garment into a rigid shell of liquid armour or a splint for a broken bone when the wounded soldier activates power supply.
In addition, the research of Massachusetts Institute of technology (MIT) in accordance to the creation of Nanotechnology was actually design from being seen by using sensors so that the uniform would also blend into whatever background might be (Uldrich J 2002). The soldiers would also wear boots that would build-up a charge of energy so that, if needed, a leap of 20 feet up would be possible. A garment with Proshied phase change fibers senses body temperature, excess heat generated by the body is absorbed into the Outlast Thermocouples and the stores heat is released back to the skin when needed (Uldrich J 2002).
With regards to environmental effect, nanotechnology has the potential to substantially benefit the environment through pollution prevention, treatment and remediation. This would include improved detection and sensing, removal of the finest contaminants from air, water and soil, and creation of the new industrial processes that waste products and are green' (environment-friendly) (Allhoff F & Lin P (eds.), 2008).
Nanotechnology has the potential to have a positive effect on the environment. For example, airborne nano-robots could be programmed to rebuild the thinning ozone layer. Contaminants could be automatically removed from water sources, and oil spills could be cleaned up instantly. Manufacturing materials using the bottom-up method of nanotechnology also creates less pollution than conventional manufacturing processes (Port, O. 2002).
In addition to the positive benefits of nanotechnology, clean energy becomes possible (Port, O. 2002). The people dependence on non-renewable resources would diminish with nanotechnology. Many resources could in fact be constructed by nano machines. Cutting down trees, mining coal or drilling for oil may no longer be necessary. Resources could simply be constructed by nano-machines.
Basically, Global industrialisation requires the rapid development of clean energy in order to preserve the clean air we all breathe. And global energy catalyst markets are huge. For instance, consider Nano stellar, a US-based company that is currently tapping nanotechnology to develop highly efficient Platinum nano-composites catalyst solution to increase the efficiency of automobile catalytic converters and dramatically reduce their cost this, according to them, is the first in a series of Nanocomposites catalyst products to address the energy catalyst, hydrogen fuel cell, and solar power and battery markets (Port, O. 2002).
Nanotechnology is expected to transform the performance of materials like polymers, electronics, paints, batteries, sensors, fuel cells, solar cells, coatings, computers and display systems. “In five years' time, batteries that only last three days will be laughable. To say that in five years, an iPod will have 10 times its current storage capacity will be conservative”, said Professor Welland. “Similarly, in 10 years' time, the way medical testing is done now will be considered crude”, he added (as cited in Twist, 2004).
Likewise, in the not-so-distant future, a terabit of data equivalent to 10 hours of fine quality uncompressed video will be stored on an area the size of a postage stamp. Clearly, the devices themselves will not be nano-sized. But nanotechnology will play its part in shrinking components and making them work together a lot more efficiently (Twist, 2004).
Conclusion
We can therefore conclude that nanotechnology is the biggest breakthrough in the present development of textile industry. This biggest advance is the new materials and products that are developed and going to be developed. In this respect, nanotechnology could enable developing nations to leapfrog older technologies. Whatever nanotechnology does for the future, it will be an evolutionary process.
Nanotechnology is a high-tech wave that is designing to sweep the world. It holds an extremely promising future for textiles. The development if ultra fine fibres, functional finishes and smart textiles based on nanotechnology has endless possibilities and at present the application of nanotechnology in textile has merely reached the starting line. In future, one can expect to see many more developments in textile based on nanotechnology.
