[ How to Revive our Textile Industry.]

The textile Industry over the last two decades has been in constant turmoil:production has migrated,with ever growing acceleration,towards Asia,particularly in India where the textile Industry was the Mother of all Industries.
Even the manufacturers of textile and textile end products has changed.So the effects have been felt by supplier industries,including raw material suppliers,fiber manufacturers,machinery manufacturers,even research organizations and trade associations.This process shows no sign of ending,presenting traditional textile manufacturers with continuing problems.
The one area of the industry which has shown strong growth and offers the opportunity for companies to expand and innovative is technical textiles:high performance materials for a wide variety of industrial and consumer end uses.So the desire to enter these markets must grow in India, In addition the big industries in India need to keep progressing in order to compete with greater involvement in Technical Textiles in India.

The word Technical Textiles was coined in the year 1980.

At a major international exhibition,Technical Textiles,was launched in 1985 to reflect the growth of technical textiles and soon developed a simple taxonomy that has been used ever since to describe the scope of this new industry and market sector:
Agrotech -agriculture,horticulture,forestry and aquaculture textiles.
Buildtech - building and construction textiles.
Clothtech - technical components of shoes and clothinge.g.linings.
Geotech - Geo textiles and civil engineering materials.
Hometech - technical components of furniture,household textiles & floor coverings.
Indutech - textiles for industrial applications-filtration,conveying,cleaning etc.
Medtech - hygiene and medical products.
Mobitech - automobiles,shipping,railways and aerospace.
Oekotech - environmental protection.
Packtech - packing materials.
Protech - personal and property protection.
Sporttech - Sport and leisure.
Within each of these headings are literally hundreds of products and applications for textiles,some traditional,some replacing other well established materials and techniques and some have been newly created by the unique properties and capabilities of textile materials and structures.The automotive industry is not only one of the largest single markets of technical textiles but also one of the most diverse.
Applications range from tyre cord,hose and drive belt reinforcement to thermal and sound insulation,safety belts and air bags,filters,cable harnesses and textile reinforced composites for body and suspension parts.
Even the internal furnishings of a car - headlines seatings,carpets,parcel shelf and trunk liners - all are regarded as technical textiles because of the extremely demanding specifications to which they are made and tested. As just one another example,the medical and hygiene textile markets ranges from high volume disposable products for baby's nappies,feminine hygiene and adult incontinence through to extremely specialized and high value textile products for use in blood filtration,surgical sutures,prostheses and most recently,scaffolds for tissue growth.
The economic importance of technical textiles.

Technology.----------------->. Consumer.------->Function . Consumer------------------> Performance.<------->Technical . Performance.-------> Interactive & advanced materials.
The new promise of technical and performance textiles is an emerging generation of products combining the latest developments in advanced flexible materials with advances in computing and communications technology,bio materials, nano technology, ( Nano technology has been described as the through three -dimensional control of materials,processes and devices at the atomic-scale level (1 X 10 to the power of -9m ).In the case of textiles,treatments on the nano scale can impart interesting properties such as water and oil repellent,stain resistance,antibacterial properties,fragrance release,antiseptic properties, etc. )and novel process technologies such as plasma treatment.These will eventually have a direct impact on all sorts of consumer textiles markets including clothing and furnishings.The field of a "wearable electronics" has already captured the imagination of many researchers and large corporations and although most products on the market today are relatively unsophisticated 'implants' of conventional electronics and wiring,the prospect of truly interactive textiles.

What is Geo textile.
A Geo textile is typically defined as any permeable textile used to increase soil stability,provide erosion control or aid in drainage.More simply put,it is made of fabric and buried in the ground it's probably a geotextile !.
Geo textile have been in use for thousands of years dating back to Egyptian pharaohs.These early Geo textile applications were basically natural fibers or vegetarian mixed directly with soil.
Modern Geo textiles are usually made from a synthetic polymer such as polypropylene,polyester polyethylenes and Poly amides.Geo textiles can be woven,knitted or non woven.Varying polymers and manufacturing processes result in a array of Geo textiles suitable for a variety of civil construction applications.
Non woven Geo textiles resemble felt and provide planar water flow.They commonly known as filter fabrics ( although woven mono filament filtration fabrics exist) Typical applications for non woven Geo textiles include aggregate drains,asphalt pavement overlays and erosion control.
A woven Geo textile is a planar textile structure produced by interlacing two or more sets of strands;slit films,which are flat and mono filaments which are round.Woven Geo textiles are generally preferred for applications where high strength properties are needed and filtration requirements are less critical.These fabrics reduced localized shear failure in weak subsoil conditions and aid construction over soft subsoils.Woven mono filament Geo textiles are preferred for applications where both strength and filtration are a concern such as shore line rip rap applications.
Geo textile related materials such as fabrics formed in to mats,webs,nets,grids,or formed plastic sheets are not the same as geo textiles.These would fall under the more general category of geo synthetics.

Rotatex & Rotaflex a product manufactured by M/s,ABG Geo synthetics:
Used in landfill,drainage and Gas dispersion is a cost saving Geo synthetic material.
Rotatex is an asphalt reinforcing system comprising grids of glass fibers coated in PVC and designed to prevent premature road break up due to increasing axle loads experienced today.
Rotaflex: Comprises the same coated grids laminated within a polyester Geo textile which extends pavement life by a factor of 10 and continues to water proof and hold surface together.
Another product by the same manufacturer Abtex N range of thick needle punched non woven Geo textile (100 - 2000 gm/m2 ) is used for protection of Geo membrane liners,filtration in coastal revetments and drainage trenches in very fine grained materials.Further another product Abtex W Geo textiles are low cost wovens used for access roads and landscaping.
Abtex N which is a chemical resistance Geo textiles are manufactured from polypropylene fibers and as such are resistant to all common chemicals found in soils.This includes acids,alkalies,chlorides,sulphates and leachate.
There products cover further,which includes lining of reservoirs,canals and environmental ponds,Basement drainage for underground car parks suitable for existing and new structures.
Traditional methods of ground water exclusion are difficult to install reliably in the modern deep basement with piled slabs and secant piled walls.This is a cost effective water proofing system. Courtesy ABG Geo synthetics

Nano Coated Textiles Kills flu Virus.
Researchers at the North Carolina State University USA,have developed a Nano coated fabric that kills or inactivates most viruses and bacteria.The key is a photo catalyst (light activated chemical) that can be applied to almost any fabric,the inventors say. When exposed to visible light,there is a chemical reaction and the fabric has been shown to kill 99.90 %of influenza virus and 99.99 % of vaccinia,which causes rashes,fever,headache and body aches.
