Potential of Non Woven, Woven and Knits in the World of Transportation

摘要

Technical and nonwoven textiles and fibres are widely regarded as the most thriving and most promising sector of the global textile industry. Innovation in new materials, processes and applications is expanding non-traditional end uses for both new and existing textile products. In short, technical and nonwoven textiles are about function rather than fashion. Nonwoven fabrics have been in use from times in memorial. Nonwovens are probably the only products to have a negative definition. It does not give a positive definition of what it is but instead states that it is not woven. With such a description it is not surprising that most people are not aware of nonwovens despite the fact that most of them may be directly or indirectly using or coming across it several times each day. It can be seen below how nonwoven have been a part of your daily life and yet some of you may not even be aware of this. The tea bag used is a light nonwoven fabric. The filter in the coffee-makar is a nonwoven. The mop used to clean the floor and the scrubber to clean the utensils is a nonwoven. The interlining of shirt collar and cuffs is a nonwoven. The shoe upper is a polyurethane coated non-woven. In car we find nonwovens. The carpet, door-panels, parcel-shelf, roof-liner etc. could all be nonwoven. The filter for the engine-air intake and the air-conditioner is also made from nonwovens. Nonwoven felts are used extensively for insulation of heat, noise and vibration (NVH components) in cars. The non wovens are also found in Rail and Road application.
