1.hi tech textile Introduction

Friction (DREF) spinning system is an Open-end and or Core sheath type of spinning system. Along with the frictional forces in the spinning zone the yarn formation takes place. The DREF spinning system is used to produce yarns with high delivery rate(about 300mpm). Still it has to gain its importance with the growth along with  hi tech textile  technical textiles in India. Amongst the spinning systems, DREF provides a good platform for production of core spun yarns due its spinning principle.It offers less spinning tension to the core and core will be positioned exactly at the centre of the yarn.

Development of DREF core-spun yarns unveils a path for new products including high performance textiles, sewing threads and in the apparels due to its exceptional strength, outstanding abrasion resistance, consistence performance in sewing operation, adequate elasticity for the stretch requirements, excellent resistance to perspiration, ideal wash and wear performance and permanent press. hi tech textile

2.0 Principle of Friction (DREF) spinning hi tech textile Systems

The friction spinning system consists of opening & individualization of fibres from slivers, reassembling of individualized fibres, twisting and winding of yarn. The figure 1 describes the DREF spinning principle where the opened fibres made roll with an aid of a mechanical roller for reassembling and twisting. Due to separate yarn winding and method of twist insertion, it has hi tech textile capability to go for high production rate.

2.1. DREF-1

DREF-1 friction spinning system was developed in 1973 by Dr.Fehrer.A.G. of Austria.The schematic diagram of DREF 1 spinner is shown in the figure 2.The fibres were opened with an opening roller and allowed to fall on a single perforated cylindrical drum slot ,which has negative pressure for fibre collection.The hi tech textile rotation of the drum impart twist to fibre assembly [1].

The ratio of perforated drum to yarn surface is very large, hence the drum speed can be kept relatively low, even if one takes the unavoidable slippage into account [2]. Due to the absence of positive control over the fibres assembly, slippage occurred between the fibre assembly and perforated roller, which reduced twist efficiency of hi tech textile . Hence this development could not be commercialized.

2.2. DREF-2

This is the development with earlier machine. DREF-2 was exhibited in the year 1975 at ITMA exhibition. The feasibility of using two perforated rotating cylinders, (as fibre collecting means), while at the same time the spinning-in of fibres into yarn occurred [3]. It operates on the basis of mechanical/aerodynamic spinning system with an internal suction and same direction of drums rotation [4]. The schematic diagram of the DREF-2 friction spinner is shown in the figure3. Drafted slivers are opened into individual fibres by a rotating carding drum covered with saw tooth type wire clothing. The individualized fibres are stripped off from the carding drum by centrifugal force supported by an air stream from the blower and transported into the nip of two perforated friction drums where they are held by suction. The fibres are sub-sequentially twisted by mechanical friction on the surface of the drums. Suction through the perforations of the drums assists this process besides helping in the removal of dust and dirt, thereby contributing to production of cleaner yarn [5]. The hi tech textile low yarn strength and the requirement of more number of fibres in yarn cross-section(minimum 80-100 fibres) were restricted the DREF-2 spinning with coarser counts (0.3-6s Ne).


2.3. DREF-3

The DREF-3 machine is the next version of DREF 2 for improving the yarn quality came to the market in the year 1981.Yarns up to 18s Ne. can be spun thro this hi tech textile  system.

This is a core-sheath type spinning arrangement. The sheath fibres are attached to the core fibres by the false twist generated by the rotating action of drums. Two drafting units are used in this system, one for the core fibres and other for the sheath fibres. This system produces a variety of core-sheath type structures and multi-component yarns, through selective combination and placement of different materials in core and sheath. Delivery rate is about 300 m/min. DREF 3 schematic diagram is shown in the hi tech textile figure 4.

2.4. DREF-5

It was developed by Schalafhorst, Suessen and Fehrer Inc. The range of count to be spun from this system is from 16�s to 40�s Ne.Production speed is up to 200m/min.The schematic diagram of the DREF 5 is shown in the figure 5. The individualized fibres from a single sliver are fed through a fibre duct into the spinning nip at an angle to the yarn axis, so that they are stretched as far as possible, when fed into the nip[7]. This hi tech textile spinning system was not commercialized due to some reasons.

PARIS (AFP) — Green-friendly fabrics may be expensive, but increasing consumer demand for the environmentally-correct now is forcing Asia's asia textile giants to go the extra mile to produce clean cloth.
In a sign of the times, at Paris' twice-yearly Texworld asia textile trade fair this week, around 60 of the 660 firms exhibiting from around the world flew the green flag, a sharp increase on previous sessions, organisers said.
In China, Bangladesh and India, the world's top asia textile producers, as well as in Pakistan, South Korea and Taiwan, natural fibres, organic yarns, fair trade practices and clean processing are creeping into an industry often chided for polluting soils, wasting water and employing child labour.
"We will be starting organic and fair trade by next year," said Sajedur Rahman Talukder, a marketing manager asia textile for Bangladesh's biggest asia textile-maker, Norman Group of Industries, whose tens of thousands of workers supply western firms such as Ikea.
"It is a market demand."
Eco-friendly fabrics, added South Korean firm Ludia, asia textile might currently be a niche product around 15 percent more expensive than run-of-the-mill asia textile, "but in two or three years the consumers will pay the difference."
"Eco-friendly is our key item, the market has changed," said a company manager.
2009 is being branded UN "International Year of Natural Fibres" to give a shot in the arm to the 40-billion-euro global annual business in cotton, linen, sisal, hemp, alpaca, jute, wool, asia textile angora, cashmere, and the like ... much of it grown by asia textile small farmers in poor nations.
"Some 30 million tonnes of natural fibres are produced annually," 25 million of them cotton, the UN's food and agricultural agency FAO said last month. "Since the 1960s, the use of synthetic fibres has increased and natural fibres have lost a lot of their market share."
But 15 years ago, Chinese entrepreneur H.L. Ding already had his sights asia textile set on homegrown hemp, a 4,000-year-old fibre used in sails for old ships that he describes as the "fabric of the future."
Strong, resistant, in need of little water or care, and no fertilisers, "it is a very special plant, the strongest of the natural fibres, even better than linen."
Five years ago, said the head of Hemp Fortex, based in Qingdao with a design asia textile studio in Seattle in the United States, almost nobody had heard of hemp. Now Nike uses the breathable, anti-bacteria, anti-UV fabric for its shoes.
"We believe organic cotton and hemp will be the main direction in the future," said Ding, whose turnover has grown from 400,000 to 10 million dollars a year selling to asia textile Walmart stores and labels such as Banana Republic and Patagonia.
Taiwan's Chia Her, a 30-year-old asia textile-maker, said it turned to eco-friendly asia textile three years ago "because it was popular in Europe." Sales of green fabrics since have grown 100-fold.
India's Vardhman Fabrics, a firm founded 40 years ago that says it is the country's top yarn producer, also tip-toed down the green path four years ago "because everyone's asking for eco-friendly to save nature from global warming."
But going green is no easy business. And the first hurdle is winning the right to tag products as being environmentally-correct.
A guide to eco-asia textile labelling published by the organisers of the Texworld fair lists around 30 eco labels variously issued in Japan, Europe and the US, that all set standards for organic asia textile and yarns as well as environmental and fair trade certifications.
"It's very expensive and very difficult to get the certifications," said Syed Adeel Haider, deputy marketing manager for Pakistan firm US Denim Mills, one of the big players on the jeans front, supplying to Levi's and Esprit.
Bringing in consultants, ensuring supplies such as yarns and chemicals met all the right standards, and re-adapting the manufacturing process called for sizeable investment, he said.
"We don't want to harm the environment, the soil or the crops, which are a livelihood for our people," he said. "So being green-friendly is a social attitude, but it's also business.
"Organic materials are in high demand and stores such as Marks and Spencers for example won't buy anything unless we're clean from the environmental point of view."
Two years ago, he said, when the firm began offering green-friendly products, there was no interest. "Now we have enquiries every day."
Even in China, world asia textile leader with a workforce of 20 million and turnover last year at 400 billion euros, green fabrics are gaining a toe-hold.
"China is receiving increasing orders for eco-friendly asia textile, with European customers handing you a thick book like a dictionary with standards and certifications, from the raw material to the finished product," said Yan York, the Chinese representative for Texworld.
"And in China too wealthy people are demanding green," he added. "They want trendy and fashionable clothes that also respect the environment."

ingapore. Asian textiles, once considered a asia textile fading industry, are now showing strong growth prospects thanks to technology and demand from expanding middle classes, a leading industry player said.

Known in the past for alley shops churning out cheap materials, many Asian companies are losing their sweatshop image as they move to compete globally, said Paul Hulme, president of Huntsman Textile Effects.

Stricter environmental standards required by Western countries are asia textile prompting consolidation and innovation in the industry, said Hulme, whose company is one of the asia textile world’s top suppliers of textile dyes and chemicals.

It moved its headquarters from Basel, asia textile Switzerland to Singapore in March to be closer to its Asian customer base .

“These sweatshops and poor facilities — that is changing,” Hulme said.

“When I visit our customers, I’m impressed with the facilities in terms of the equipment, in terms of the housekeeping standards and the way they treat their employees. I would not pretend that sweatshops don’t exist. I’m sure you can go to parts of India and China where that is the case. But I think that image will asia textile change.”

Hulme said the global asia textile dyes and chemicals market was worth $16 billion, and Asia accounts for some 45 percent of total consumption, much of it destined for export markets.

“The market is changing, customer taste and demand is changing. For example, as you go into the provinces in China, the spending power is increasing,” said Hulme.

“In this business, the future is in Asia. It’s going to be driven from Asia, not from Europe and America. You’ve got to be part of the region.”

China, Bangladesh and India are the world’s top asia textile producers and are major consumers. Pakistan and Southeast Asia are important and growing players.

Apart from apparel, a major driver for the industry is demand for “technical asia textile” or fabrics used in cars, mattress covers, bags, tents and parachutes, among others, Hulme said.

Car fabrics that do not fade easily even in extreme heat enhance the vehicle’s resale value, and there is rising demand for fire-resistant materials in the construction sector as well, he said.

In the medical field, chemicals are incorporated in surgeons’ gowns to repel blood and dirt, raising the hygiene level.

As Asia’s spending power rises, “people want different products and that’s going to lead to the development of a whole new market for technical asia textile which didn’t exist before,” said Hulme.

The market for technical asia textile is likely to grow by 20 percent per year over the next decade, he said, urging Asian companies to ride the growth by moving up to higher value-added products.
