They are not made by weaving or knitting anddo not require converting the fibers to yarn. Nonwoven fabrics are flat structures mainlydefined as sheets or webs made by bonding andentangling fibers or filaments by mechanical,thermal or chemical means.NONWOVEN FABRICRef-INDA LOGO-About nonwoven
Technical Textiles are defined as Textilematerial and products manufacturedprimarily for their Technical performanceand functional properties rather thanaesthetic and decorative characteristics.TECHNICAL TEXTILERef:- Technical textile and nonwoven
Fibre use:- polyester and polypropyleneThe bonding technique mostly used isneedle-punching because needlepunched nonwoven is flexible withrelatively sufficient strength,Making:They are permeable toboth air and water; can beengineered to UVstabilized, and mildewresistant, rot resistantand resistant to micro-organisms. The porousstructure allows light andsun-rays to pass through
Making: The technology used for making geotextilesis needle punching..The three main properties which are requiredand specified for a geotextiles are itsmechanical responses, filtration ability andchemical resistance
Material usenonwovens include fiber, filament, filmsare antimicrobial finishes. Fibers usedmust be non-toxic, non-allergic, non-carcinogenic .Disposable mask is expected to protect 98% of the bacteria , itshould not cause skin irritation, and has to be water proof,therefore SMS structures are used.Uses:-Nonwoven used in gauze swab should absorb exudates, gauzeare normally highly absorbent, softer and have good airpermeability
In a car non woven used instead of the heavy metal.It used in tank ,wheel,barrierMobiltechComponents of seats , disposable head-rest covers, covers of innerpanel of cars and automobiles.

CONCLUTION Technical textiles are generally recognised to be one ofthe most dynamic and promising area for the future ofthe textiles industry. Improvement in nonwoven technology is leading tosignificant cost savings in some cases and enhancedperformance and durability in a vast array ofapplications. Nonwoven fabric gives options of having very lightweight, thin, porous material at reasonable priceperformance ratio for various technical applications. Eco friendly products may be developed from naturalfibres. Versatility.
