Biomimetics Colouring Textiles without Dyes

Through the course of billion years, nature has gone through a process of trial and error to refine the living organisms, processes and materials on planet Earth. The emerging field of Biomimetics has given rise to new technologies created from biologically inspired engineering in both the macro scale and nano-scale levels. Biomimetics may also offer solutions to environmental and social problems caused due to dyeing. Dyes have been recognized as carcinogenic and harm the flaura and fauna as well. Natural color mechanisms and structural study of such natural phenomenon may offer best alternate to dyes and therefore may revolutionize the dyeing and printing industry. Animals, plants and insects in nature evolved over billions of years to develop more efficient solutions than comparable man-made solutions to date. Some of these solutions have inspired humans to achieve outstanding outcomes. Several examples can be quoted for this and self cleaning materials which are derived from emulating the lotus leaf effect, production of hollow fibers inspired from polar bears, etc are just a few of them. Why do we need a substitute for dyes? Dyes usually are of synthetic origins and have aromatic molecular structures. The dye effluents are highly coloured and their disposal

Enabling the Efficient Exchange of Information

The RFID market is set for further robust growth despite many a challenge. While turnover is likely to increase by an average of 19% p.a. in Germany between 2006 and 2016, the pace may reach as high as 25% p.a. worldwide. With the shift in the market shares of individual RFID components and the exodus of production of less sophisticated products from the high-wage countries, Asia is likely to contribute an ever increasing share and become the continent with the strongest turnover by 2016.

RFID links the physical good with the corresponding information. In fact, the RFID principle has been used in a broad spectrum of military and civilian applications for decades. However, it was not until the introduction of the electronic passport and the use of RFID tags on some consumer goods in the retail sector that public interest in the technology surged.

Political and technological challenges will shape RFID’s commercial outlook. In the technology area, the issues seem to focus primarily on energy consumption, production costs, manufacturing speed and reading errors, while politically the focus will be on frequency harmonisation, standardisation, and environmental and data protection.

Not every RFID project driven by a technological vision

A Tool for Denim Processing

Over the last eight years, Ozone has made a prominent place for itself in the garment processing industry all over the world. Widely used as a bleaching agent, Ozone remains a powerful, secret tool within the denim industries that gave denim garments an unique and distinctive look and feel from other traditional processing.

Even today, many manufacturers in India still feel that by using Ozone Gas their denim garments they would simply bleach them to lighter blue only. This is true since the Indian denim manufacturers and users are used to the brighter colour of Indigo achieved with the help of optical brighteners that sometimes it is difficult for them to accept the duller colours achieved through Ozone processing.

Though it changes the colour of the Indigo dye, Ozone eliminates tinting from the reverse of the denims as also from the sewing thread, pocket fabric, labels, zippers, buttons etc. giving the garment a cleaner look. Ozone also destroys all air borne micro-organisms including bacteria, virus, mold, fungi, spores, etc. It also oxidizes the volatile organic chemicals, including aromatic chemicals reducing them into lower molecular organics which are no more aromatic in nature; hence the hand-feel

New technology promises fast, accurate stroke diagnosis

Minutes count when treating stroke, but current diagnostics take as long as three hours, careful lab work, and skilled technicians to arrive at a conclusive diagnosis. Scientists at Cornell University’s Baker Institute for Animal Health have developed a device that helps diagnose stroke in less than ten minutes using a drop of blood barely big enough to moisten your fingertip. Having demonstrated proof of principle, the technology could eventually be expanded and used in point-of-care testing devices to diagnose other conditions in humans and animals, including traumatic brain injury (concussion), some forms of dementia, and even some types of cancer and heart disease. The study appears in the journal PLOS ONE.

The study’s lead author, author Roy Cohen, a Research Scientist at the Baker Institute, says the technology represents the successful pairing of two big goals in medical diagnostics–small size and simplicity–a combination that means testing could be carried out at a patient’s bedside.

“Three quarters of stroke patients suffer from ischemic stroke — a blockage of a blood vessel in the brain. In those cases, time is of the essence, because there is a good drug available, but for a successful outcome it has to be given within

Textile takes a step towards the future with IT

The infrastructure of any industry is based as much on technical support system as it is on human resource.

The expanding world of flawless machines and superior software programmes has made it mandatory for industries to adapt to technology to communicate with customers, find prospective consumers, understand market requirements, keep an inventory and many other aspects.

What was once a Herculean task, either ignored or done manually, was prone to error. Now, it is easily done with information technology. This has brought with it operational efficiency, stronger customer loyalty, better security and higher profitability in the technologically advanced textile and apparel industry.

IT leads the way
Information technology (IT) has touched every aspect of the textile and apparel sector. It is required at every step from yarn production to finished product. One of the reasons of increased dependency on IT is the changing demographics and pace of growth in the fast-paced market environment in the Asian subcontinent. The average age of the population likely to splurge on clothes has decreased considerably. Earlier, teenagers and office goers conveniently ignored attire or spent very little on the same. Today, there is increased awareness among teenagers and professionals that apart from style statements, clothes also symbolise

A cloudy state of things

The phenomenal evolution of telecommunications now makes cloud technology accessible everywhere. An apparel executive can now see whether they are at the sewing stage of a manufacturing cycle or at that the goods are already in transit and where it is in the world. Since supply chain and logistic analysts of a brand can now track in real time every step of a supply chain, informed decisions and forecasts for capacity management and contingency planning have become easier. All these lead to a much streamlined industry.

If there is any sector that has been totally transformed – or is in the process of being transformed – by cloud computing, it is logistics and supply chain management. In many ways, the cloud concept itself was tailor-made for this industry because of its global scope and involvement of stakeholders.

The cloud allows data from many sources to be centrally collected, transformed, and presented in dynamic dashboards. Therefore, by taking recourse to the cloud, supply chain and logistic analysts can track in real time every step of a supply chain. This results in informed decisions and forecasts for capacity management and contingency planning. Since cloud platforms for logistics are far more dynamic and

Scope for sustainable technologies is huge

Sustainable technology refers to that which caters to the needs of the present without compromising the ability of future generations to meet their own needs. It enables more valuable use of natural resources and greatly reduced ecological impact among other technological benefits. Though sustainable technology deals with energy efficiency, reduction in pollution, use of renewable sources, it should also be economically sustainable too, says Avinash Mayekar.

The consumption of natural resources has increased exponentially in the past decades in rapidly industrialising countries and it is rather recently that we have started recognising the unpleasant consequences of the carefree attitude towards the environment.

The textiles industry is among the most essential consumer goods industry in the world, as it fulfils one of the basic needs of human beings. Today, the world of fashion is glamorous and stylish; however, its impact on ecology is worsening day-by-day. The textiles industry is condemned as being one of the most polluting industries in the world. Not only production, but even consumption of textiles produces waste. At every stage of textile production, vast amounts of energy, clean water and chemicals are used to process textiles and apparel. In turn, these processes generate air, water and soil

Cellular textile and 3D Printing: Designing for perfection

Technology has been changing the face and nature of work and the value of skills since the starting of the industrial revolution. This has resulted in change in demand for conventional skills. In textile sector also, the technology has evolved and today even the most basic process of knitting and weaving have changed. Today textiles known as cellular textiles can be created with the help of 3D printing. The complex interlocking patterns have not deterred the young designers from learning and adopting this new skill as part of their designs. Until only last year the cellular textiles and 3D printing were seen as futuristic textile. Nevertheless, some top-notch designing houses and designers have already started displaying cellular textile on ramp and this has made cellular textile a part of the contemporary design rather than a futuristic one.

The most miraculous aspect of this new textile is that a little modification in the structure of the textile can give fabric diverse properties. The cellular textile repeats the interlocking units that differ to create varied functions of flexibility and stretch throughout a textile. As per the ongoing efforts, a software is being developed to help the cellular

The designer of tomorrow

The fashion industry is predicted to change as much in the next ten years as it has over the last 100. Consolidation, computerization and globalization are the major disruptions of today, and will continue to be as they morph and change. Fashion designers are at the forefront of these disruptions.

In partnership with the Council of Fashion Designers of America (CFDA), a not-for-profit trade association whose membership consists of more than 450 of America’s foremost womenswear, menswear, jewelry and accessory designers, Lectra surveyed the leading professionals working within today’s ever-changing, fast-paced international fashion and apparel industry.

This investigation explores why and how the role of the fashion designer is changing. It presents the most important challenges, disruptions and changes that affect fashion designers today… and will continue to influence the profession for years to come. We piece together a vision of how next-generation fashion designers continue to create in today’s modern fashion environment.

Great expectations
“As a fashion designer, I was always aware that I was not an artist, because I was creating something that was made to be sold, marketed, used, and ultimately discarded.” Tom Ford.

Arguably, designers are artists. Today, a new dichotomy between artist and technician lies at the heart of

Affective computing and its applications in the apparel retail industry

“Any sufficiently advanced technology is indistinguishable from magic”, said Arthur C. Clarke, author of many science fictions. Technology has an important role to play in transforming businesses in a big way. With the growing usage of smartphones and tablets, apparel retailers want to use technology to their advantage to stay ahead in the times of fierce competition.

For apparel retailers and in the fashion industry understanding consumer behaviour is a direct route to achieving higher revenues and better sales. Data analytics and sensors are a few methods used in the sector for making better decisions. Lately advances in the field of neuroscience can reveal a great deal about emotions that are at the very crux of human decision making. Essentially emotions trigger the way individuals engage with brands and products rather than cognitive thoughts.

Conventionally used techniques like surveys and focus groups do not measure emotional responses accurately and are prone to biases. They fail to capture honest, unfiltered, and spontaneous feelings. It would be so much simpler if just by reading the facial expressions, gestures, voices, heart rates, and sweat to identify the emotions of an individual. Enter affective computing, a technology that does just that through personal devices like

Electrospun nanofibre technology Stops bleeding instantly

Healthcare is expanding at an astonishing pace all over the world. Quality medical assistance is one of the top priorities. While the expertise of the medical practitioner’s skill is vital to ensure quality treatment, it is also the use of medical technology and advancements that reap favourable results. Over the years, with rise in demand for developments like anti-bacterial bandages, scaffolds for tissue culture and prosthesis for implants, medical textile has taken a new meaning. Medical textile’s application in wound healing and infection control is appreciated for assisting rapid recovery.

Professionals in life-threatening work like fire fighters, military and police personnel benefit from advancements in medical textile. Hospital emergency rooms witness several critical cases every hour where medical textile can save a patient’s life.

One of the recent breakthroughs in medical textile is nano bleed-stop technology. Textile applications of nanotechnology are already growing and the recent addition of nano bleed-stop technology will strengthen nanotech medical textile made from electrospun nanofibre technology.

Application in textile
Electrospun nanofibre technology has revolutionised the medical industry. However, nanofibre net is delicate and cannot be used on its own, so conventional dressings are coated with electrospun nanofibre to harvest their full potential. Electrospun nanofibre dressing enhances moisture management

Application of Biotechnology on denims

Biotechnology is changing the production of denim fabric

Biotechnology is a group of technologies which is characterised by working with organisms and their products. This is done with the aim of improving our lives. Modern biotechnology has a great effect on world economy and society. The best example of that is genetic engineering, a process of modifying genes in an organism to remove or add any characteristic. Modern biotechnology has a huge application in textiles like in enzymatic desizing, enzymatic scouring etc.

Use of enzymes has gained global recognition as it is non-toxic and eco-friendly. Enzymatic applications are mainly in textile wet processing and few areas of textile processing. Other advantages of enzyme technology is comparatively lower cost, less processing time, energy and water savings and improved quality. Enzymes are proteins which consist of long linear chains of amino acids that produce three-dimensional products. Each amino acid sequence has a unique property. Novozymes has recently performed two life cycle assessment at textile mills in China. One is bioscouring, which removes impurities in the cotton. The other is bleach clean-up to remove excess bleaching agent prior to dyeing.

Washing clothes improve their comfort. The

Technology in World of Fashion

An ever-growing progress in technology is not just limited to the retailing and manufacturing industries of the textile industry. It is also seen in textile logistics. Textile logistics make use of advanced transportation that is speedier and cheaper than ever before. They also make sure that the mode of transport is environment friendly. The concept of sustainable modes of transportation is getting popular all over the world.

In fact, the concept of sustainable technology is strived for in modern times. Consumers understand the value of eco friendly products and are willing to pay any amount of money to obtain the same. Machines that consume less energy, water, and fuel are made use of in manufacturing units. Machines that produce lesser waste and consume lesser raw materials to manufacture textiles are utilized in the fashion industry.

Fashion industry, like all others, makes immense use of technology. But there is room for more. Manufacturers and retailers indulge in market research to understand market requirements in deep. They look for technologies that make their goal of satisfying market demands easy. Machines and software that are relevant are purchased for any amount of money. Thus, technology is something that rests in the heart

Introduction to Plasma

Modern science reports the existence of three states of matter, namely solid, liquid and gas. Most people, however, thanks to the advent of modern television displays, are vaguely aware that a fourth state known as plasma also exists. Fortunately, plasma exists in various forms, and a lot of it can be harnessed to study and possibly achieve desired outcomes on various substrates, including textiles.

Simply apply plasma is nothing more than ionized gas. When the temperature of a gas is raised its molecules gain energy until a point reaches when the molecules gain enough energy to make the electrons in the gas

Habert Spencer said “The consciousness of being well dressed gives peace such as religion cannot give.” Dress has become a vital part of our living. Aesthetically dress serves two purposes, it helps to accentuate the

Application of Robotics in Textiles

Application of Robotic automation in the textile industry provides so many benefits like labour savings, reduced cycle times, improved part quality, improved safety, increase productivity and efficiency. The application of such Robotic automation has resulted in significant benefits to textile industry. High levels of consistency and precision in work pieces and high levels of repeatability and accuracy in manufacturing equipment have been required. Economic Justification can be shown only for large quantities of production. To achieve this, we need adaptive manipulation systems having some “Artificial Intelligence”. This article shows a wide range of automation in textile process by using robots which ultimately increase the both basic requirement of textile industry i.e. productivity and efficiency.

Robots are being used in textiles today with substantial developments already being made and the future use of this new technology will develop as the economics of each area of manufacturing dictates. These are machine systems that can be conveniently directed to change their mode and sequence of operations by means of software instruction. Ideal examples are numerical controlled machine tools and industrial robot arms. These programmable systems still require high levels of consistency, precision, repeatability and more importantly, adaptability.

Self-repairing textiles mending its way into future

Smart textile innovations are opening up a brand new avenue for producers and bringing new purposes to it, moving beyond the conventional. Today, textiles are being used for architecture, in wearable technologies, as environmentally responsible fabrics, and bio leathers. With the help of nanotechnology many value additions can be made to a normal piece of textile material.

Taking the textile industry a step further to the future of fabrics is a mind blogging invention of different self-healing materials. There are several strategies used in the industry to achieve such results on fabrics such as reversible cross-links, using nanotechnology that releases healing agents, and employing technologies like shape memory effect, nano particle migration, electro hydrodynamics, conductivity, and co-deposition.

The self-healing or the automatic repairing gave rise to the innovative idea of self-repairing textile materials. However, the concept of self-repairing has been common in the plastic, ceramic, and metal industries. Increasing the life of assets can be a huge cost saving for consumers and will become a highly desirable product in any sector. There is a huge buzz around the business of self-repairing products. Around 200 papers have been published in the year 2011 generating curiosity everywhere. Re-healable polymers and composites are popular technologies

E-Commerce in Textile and Apparel A FUTURE TREND

E-commerce is an exemplary concept in the future of textile and apparel industry. It is playing a major role in the present scenario of textile and apparel industry. It is also very significant that the future of textile and apparel industry is complete only with E-commerce. Diverse e-commerce applications are being implemented in the textile and apparel supply chain. Information and communication technologies (ICTs) have the capacity to make extravagant amounts of information available to users located in various parts of the world. ICTs also facilitate rapid communication between them. One application of these technologies is in the development of e-commerce to support electronic trading.

E-Commerce A New Concept and Scope

E-commerce can be specified as any form of economic activity conducted through computer-mediated networks. The potential of e-commerce caught public’s attention as a result of ventures such as the electronic bookshop. As a result there are a growing number of other Internet-based retailers in the business-to-consumer (B2C) e-commerce area. However, business-to-business (B2B) ecommerce is growing much more quickly than B2C forms of electronic trading. E-commerce is a new and exciting technology, attracting much interest. It has the power of fundamentally changing the ways in which companies do business. It is having

Process-integrated Resource Management

Process-integrated Resource Management-An Efficient Instrument for environmentally Friendly Textile Finishing

Environmental awareness has long ceased to be the preserve of production plants in Europe. In the so-called developing countries, authorities are focussing increasingly on big polluters. Unfortunately, in this context textile wet finishing has an extremely bad reputation all around the world. However, there is some hope that a new, integrated environmental concept from Swiss textile machinery manufacturer Benninger, which can run without producing any waste water at all, may well make this bad reputation a thing of the past in the next few years render this negative reputation a thing of the past

Worldwide, only around 10% of total water consumption is accounted for by direct human needs .The lion’s share of 70% is used in agriculture, and the remaining 20% is used in industry. Regional variations give an indication of the degree of industrialisation of the different national economies. For example, China uses 80% of its water to irrigate fields, whereas in Europe half of the water is pumped into factories. All this is in stark contrast to the geographical distribution of the resource “water”. While China is home to around 20% of the world’s population, it only has access

Design and Technology Interface in Global Economy

In current scenario of Indian Textile Industry, technical developments are not blended with good design and design developments lack technical feasibility. The mutual inter-dependence of design and technology has little been put to practical use for the benefit of the user.

New technological innovations need to be utilized by textile designers to develop aesthetically attractive and functionally relevant products/solutions for the benefit of the industry. Design needs to innovate and find the alternative applications of the technology and similarly technology needs to innovate to support new design trends and designers’ aspirations. The approach will help to foster innovation in our products and create a competitive edge in the global market place.

Proposed paper will initiate a dialogue on above issues related to technology and design interface. Following are the key areas of discussions with Indian context:

  1. State of Indian textile industry
  2. Technology, design and consumer preferences
  3. Innovation and textile Industry in new economy
  4. Textile design- role and responsibility
  5. Creating innovation culture and managing new frontiers

Changing Face of Indian Industry

Indian textile industry is at crossroads today and apprehensions are many. Some of the fears are worst than the times when we faced the closure of a large number of mills. However, this time the fear is not only
