Application of Non Woven Fabric in Automobile Industry

In recent years, non-woven fabrics are widely used in the automotive industry. The performance of non-woven fabric can realize auto parts of good performance and security, and make the car weight, improve comfort and highlight car of the beautiful, advanced technology can make automobile heat insulation, fire, waterproof, against extreme temperature, greatly improve the effect of wear and tear.

They continue to replace products made of textiles, plastics, metals, or other heavier materials.

Compared with textile fabrics, non woven materials are easier to be engineered and can be deeply molded to meet the requirements of complex surface shapes of various interior accessories. At the same time, the thickness, hardness and other indicators of the materials can be personalized according to the requirements of automobile manufacturers. In addition, non woven materials can be used in many parts of the cockpit, making it consistent in color and structure, and showing better color fastness to wear.

Compared with other textile fabrics, non woven materials have more balanced tensile properties both vertically and horizontally, and they are more uniform in appearance after molding.

At present, non wovens have been used in many parts of automobiles. Its application in the car is mainly divided into two parts, the power train part is mainly used for the car hood, filter (including the air conditioning filter in the compartment, engine filter, etc.), battery diaphragm and sound-absorbing materials (including the dashboard rear and wheel cover);

Interior applications include car ceilings, carpets, sound-absorbing materials and seat materials.

At the present stage, the floor material is still the largest application of non wovens in the automotive interior, and the ceiling is the second largest application field, spun bonded non wovens are mainly used as reinforcement material and backing, and dry non wovens are used as surface covering material because of their excellent coverage and uniformity.

Generally speaking, the development of automotive non wovens mainly revolves around comfort, safety and environmental protection. Comfortable, including quiet inside the car, air purification of the air conditioning function, in the form of sound-absorbing materials, heat insulation materials and other solutions; Safety is reflected in the improvement of flame retardancy and durability; Environmental protection is not the use of environmental pollution substances and VOC (volatile organic compounds) to produce the possibility of substances, and efforts to reduce the use of car energy and carbon dioxide emissions.

For the above requirements, not only need to develop environmental protection technology, such as seeking automobile lightweight, recycling, etc, the products at the same time should also make non wovens high functional, such as the use of flame retardant fiber, PPS fiber and other high-performance materials, also can undertake multiple functions, such as using ultra-low weight sound-absorbing insulation, multi-functional product development, etc.
