Introduction Of Specific Uses Of Decorative Nonwoven Fabric For Automobiles

The rapid development of the automobile industry has led to a sharp increase in the amount of textiles used in automobiles. Non Woven Fabric technology continues to meet the various needs of the huge automobile market, and its application has been growing. Automotive non woven materials mainly include automotive carpet base fabrics, automotive decorative carpets, roof fabrics, door panels and seat pads, trunk linings, and automotive Filter Cloth materials.

1. Car Carpet
Car carpet should not only increase the luxury and comfort of the car, but also have the properties of sound insulation, moisture resistance, shock absorption, stain resistance, good color fastness, mildew resistance, fluff not easy to fall off, flame retardant and other properties. At present, there are mainly two types of car interior carpets: tufted carpets and needle - punched carpets. Low - grade carpets are mostly of polypropylene staple fiber needle - punched and then dipped ( semi - impregnated or fully - impregnated ) type; medium and high - grade automobiles are mostly tufted or needle - punched velvet carpets, and the base fabric of velvet carpets is mostly spunbond.

Car interior veneers and roof fabrics used to be mainly nylon knitted fleece fabrics, which have now been partially replaced by Needle Punched Non Woven Fabric. Needle Punched Non Woven is beautiful and cheap as roofs, but the disadvantages are low tear strength, long elongation, and poor shape after molding. Therefore, a method of laminating and compounding a Needle Punched Nonwoven and a Spunbond Nonwoven is currently tending to overcome this shortcoming.

3. Cushion material
The padding materials include door soft pads, roof pads, rear luggage pads, seat pads, sound insulation pads, sun visor soft pads, etc. The basic performance requirements for such materials are wear resistance, no pilling, good resilience, low density, good sound insulation and thermal insulation. Generally, most of these pad materials use polyester and polypropylene staple fibers as raw materials, and are made of high - loft non woven fabrics by needle punching. In order to reduce costs and improve sound insulation, from the perspective of environmental protection, recycled fibers have been widely used.
4. Automotive filter material
There are many places where filter materials are needed in automobiles, such as carburetor air filtration, air conditioning circulation filtration, cabin air purification crankcase ventilation valve filtration, engine lubricating oil filtration, transmission oil filtration, wiper water filtration, etc. At present, many of the above - mentioned filtration media developed and applied use Non Woven Fabric Roll or composite non woven fabric. For example, the circulating filtration system of the driving air conditioner adopts a composite material of electret Melt Blown Nonwoven and activated carbon. Tank oil filtration adopts needle punched non woven fabric, etc.
