MOBILTECH (AUTOMOTIVE TEXTILES)
Nylon tyre cord fabric provides strength to a tyre. The tyre industry consumes nearly 98% of the total nylon tyre cord consumption. The nylon tyre cord fabric is 100% technical textile. Nylon tyre cord fabric gradually replaced the usage of rayon and polyester cords in the tyre industry. Nylon 6 grey and dipped tyre cord fabrics having high strength, fatigue resistance, impact resistance, high adhesion characteristics, are mainly used as reinforcements of bus/truck tyres. The tyre cords are generally available with the fabric characteristics of 930dtex, 1400dtex, 1870dtex, 2100dtex. The critical specifications drive the characteristics such as breaking strength, elongation, adhesion, ply twists and hot-air shrinkage.
Seat belts function as a safety harnesses which secure the passengers in a vehicle against harmful movements during collision or similar incidents. Seat belts minimise injuries during accidents. Seat belts are woven narrow fabric made from nylon filament yarns or high tensile polyester filament yarn. The load specification is an important criterion for usage in vehicles. At present, the seat belts, which are used in the cars, are called three-point which has single continuous length of webbing. They are called three-point because these belts help spread out energy of the moving body in a collision over the chest, pelvis and shoulders. The seat belts are made from nylon filament yarn or polyester filament yarn which is woven to produce the webbing pattern. The linear density of synthetic yarns should be between 100dtex and 3000dtex, preferably 550-1800dtex. The filament linear density should be between 5dtex and 30dtex, preferably 8-20dtex. A typical seat belt is made of 320 ends of 1,100 dtex polyester each. Most weft yarns made from polyester are 550dtex.The critical characteristics of the webbing are abrasion resistance, resistance to light and heat, capable of being removed and put back in place easily and good retraction behaviour.
Woven seat cover is one of the important contributors of technical textile in an automobile. With gradual improvement in vehicle models and increased emphasis on luxury and comfort, the seat cover market has witnessed uptrend in the market. Seat covers are made from cotton, vinyl, velvet and leather. The fabric used for the manufacture of seat covers is woven on looms. The desired product characteristics are durability, ultra-violet fade and wear resistance, water-proofing, flexibility and stretchableness. The type of seat cover used varies based on the automobile model and desired styling of the upholstery. The yarn required for the seat covers is in the range of 500 deniers to 1300 deniers.
Airbags are inflatable protective equipment which reduces injuries during an accident or impact in co-ordination with the seat belt. The airbags are manufactured by using the yarn / fabrics, primarily nylon 66 or polyamide 66, lighter denier and silicone coated.
Helmets are used as protective headgear for two wheelers. The typical motorcycle helmet has an inner layer of polystyrene or polypropylene foam and an outer layer made of plastic, glass, and other synthetic fibres. The chief purpose of a helmet is to absorb the impact of a crash and thus prevent primary injury to the brain, rather than preventing skull and face fractures. The outer shell is made from Acrylonitrile-Butadiene-Styrene (ABS) or Polypropylene or glass fibre plastic which is hard in nature. The inner side of the shell is expected to provide cushion to the rider and is made from regulated density concussion padding.
In Railways, the material for seat berths fabric is the key technical textile usage. Material used in the berths is polyurethane foam and Rexene cloth. Rexine material is used in railway seat covers. The Rexene material is constructed from single or multiple poly vinyl film layers with choice of backing cloth. Synthetic cloth like polyester and rayon is used. The Rexene material is fire retardant coated fabric.
Head rest covers, tea pot covers, Head phone bags are the major Air craft disposables used in the Air crafts.
