Now a lot of materials used in automotive interior decoration are made of non-woven fabric, such as car ceiling, car mat, car interior decoration board decoration and so on are made of non-woven fabric, so as automotive interior decoration, non-woven fabric needs to have those several requirements, we have a total of four points to understand.
Non Woven Fabric
1. Breathable and moist
Needle-punched non-woven fabric is generally used in automotive interior decoration, are in the middle and low - end cars, generally in the camry this level as a division.Needling and sewing, generally used for low and medium cars, high cars are woven, when the ceiling molding will be added to the non-woven spunbonded fabric for reinforcement.There are two kinds of non-woven fabric and knitting.Non-woven fabrics and: needling, sewing (mainly malefice sewing), depending on your use in fabrics or ceiling reinforcement.
Medium and high-grade materials, now more and more car models change to this material, no yarn seam knitting ceiling: polyester material, with coil structure, very similar to warp knitting, characterized by good elasticity in the direction of thickness.Needle-punched ceiling: polyester material, the effect is furry, low - and medium-price, many cars, vans used

2. Anti-ultraviolet and light resistant
Automotive textiles must have good light resistance and uv resistance.Large cooling and heat cycle may affect the fading and degradation of fabrics, not only affecting the service life of materials, but also greatly affecting the aesthetics of fabrics after fading.As the sun sets, the temperature inside the car drops, greatly affecting the relative humidity of the car.As the sun rises, the interior temperatures can reach 130 degrees Celsius in some extreme weather conditions.In order to meet the requirements of lighting and lightweight of modern cars, window glass starts to occupy a large area, which leads to the influence of light on the interior space of cars.

3. Atomization performance
Due to the large surface area of the fibers on the front of velvet fabrics, the rime phenomenon will be more serious, resulting in severe atomization due to the accumulation of chemical agents used in the process of yarn weaving, dyeing and finishing. This problem must be strictly controlled.The surface area of fibers on the front of velvet fabrics is large, and the rime phenomenon will be more serious, if the fabric has not been tensioned for a long time.Therefore, automobile interior fabric must have certain anti-atomization performance."Rime" on the window glass is difficult to remove, will seriously affect the line of sight, and suspended in the air volatile matter may be inhaled into the human body, which affects people's health and safety.These volatile substances in the heat will volatilize condensation on the Windows and windshield, in its surface to form a "rime" phenomenon.Therefore, the finished automobile interior materials may contain many low-molecular volatile substances.Automotive interior materials are functioned prior to use, and adhesives are used during installation.

4. Abrasion resistance
Martin dale method and taber wear - resistant tester are common testing methods for automotive textiles.Car seat fabric needs to have a high wear resistance, so that it does not ball in the use of the process, not hook wire to ensure the seat aesthetics.In some cases, it may be more than 10 years old or even longer, and the seat fabric is generally at least 2 years old.Wear resistance is the most important requirement for automobile seat fabric and steering wheel fabric.
5. Flame retardant performance
Pay special attention to your choice.Generally speaking, the flame retardant performance of automotive interior materials is evaluated by horizontal combustion test.Its thermal properties and combustion properties are also different.Textile materials for vehicles may use various fibers, which have different compositions and chemical structures, to ensure sufficient time for passengers to leave in case of a fire hazard, or to reduce the risk of fire.Automotive interior materials, especially textiles, must have a good flame retardant and flame retardant non-woven fabrics.
