Now many materials of car interior are made of non-woven fabric, such as car ceiling, car mat, car interior board decoration and so on are made of non-woven fabric, so as car interior, non-woven fabric needs to have the several requirements, we sum up four points to understand.
1. Breathable and wet
Needle-punched non-woven fabric is generally used for automotive interior decoration, which is in the middle and low grade car, generally with camry this level as the boundary. Needling and sewing, generally belong to low and medium cars, advanced cars are made of woven, spunbond non-woven fabric will be added to reinforce the ceiling when forming. There are two kinds of non-woven and knitted. Non-woven fabric and: needle-punched, stitched (mainly horsepower frith stitched cloth), see you use in the fabric or roof reinforcement.
Medium and high-grade materials, now more and more models change this material, no yarn seam knitting ceiling: polyester material, coil structure, very similar to warp knitting, the characteristics also lies in the thickness direction of good elasticity. Needle ceiling: polyester material, the effect is furry, low price, many cars, vans
2. Uv resistance and light resistance
Automobile textiles must have good light resistance and uv resistance. Large heat and cold cycles may affect the fading and degradation of the fabric, which not only affects the service life of the material, but also greatly affects the beauty of the fabric after fading. As the sun sets, the interior temperature drops and greatly affects the relative humidity of the compartment. As the sun rises, temperatures inside the train can reach 130 degrees Celsius in some extreme weather conditions. In modern cars, in order to meet the requirements of lighting and vehicle lightweight, window glass begins to occupy a large area, which leads to the influence of light on the interior space of the car.
3. Atomization performance
Because of the large surface area of the fibers on the front side of velvet fabrics, rime is more serious and can cause serious atomization due to the accumulation of chemicals used in yarn weaving, dyeing and finishing. This problem must be strictly controlled. Velvet fabrics have a large surface area on the front, and rime is more severe if the fabric has not been drawn for a long time. Therefore, automotive interior fabric must have a certain anti-atomization performance. The "rime" on the window glass is difficult to remove, will seriously affect the line of sight of the company and passengers, and the volatiles suspended in the air may be inhaled into the human body, and then affect people's health and safety. These volatiles in the heat of time will volatilize condensation on the window and windshield, on the surface of the formation of a "rime" phenomenon. Therefore, the finished automotive interior materials may contain many low molecular volatile substances. Automotive interior materials are treated for various functions prior to use, and adhesives are used during installation.
4. Wear resistance
The common testing methods for the wear resistance of automotive textiles are Martindale method and Taber wear testing machine. Car seat fabric needs to have high wear resistance, so that it can not ball in the use of the process, no hook to ensure the seat beautiful. In some cases, it may be used for more than 10 years or even longer, and the seat fabric generally needs to be used for at least 2 years. Wear resistance is the most important requirement for car seat fabric and steering wheel fabric.
5. Flame retardant performance
Be careful in your choice. Generally speaking, horizontal combustion test is commonly used to evaluate the flame retardant performance of automotive interior materials. Its thermal and combustion properties are also different. A variety of fibers may be used in automotive textile materials, which vary in composition and chemical structure, to ensure that passengers have enough time to get out of the vehicle in the event of a fire hazard, or to reduce the risk of fire. Automotive interior materials, especially textiles, must have good flammability and flame retardant, flame retardant non-woven fabric.
