Nowadays, many materials in the automobile interior are made of non-woven fabrics, such as automobile ceiling, car footrest, automobile interior panel decoration, etc. are made of non-woven fabric. Then, as an automobile interior, there are several requirements for non-woven fabrics. We have summarized four points to understand.

1. air permeability and moisture permeability

Needling nonwoven fabric is generally used for interior decoration of automobile, which is on medium and low-grade cars, and generally, kemeria is the boundary. Needling and sewing are generally used for low and medium-sized cars, and high-grade cars are woven. When the roof is formed, it will be reinforced by spunbond non-woven fabric. There are two kinds of non-woven fabric and knitting. There are also non-woven fabrics: acupuncture, sewing (mainly horsefris), to see if you use the fabric or the roof reinforcement.

Medium and high-grade materials, more and more models are changing this material, without yarn seam knitting ceiling: polyester material, with coil structure, very similar to warp knitting, and the characteristics are good elasticity in thickness direction. Needled ceiling: polyester material, the effect is fluffy, the price is medium and low, many cars, van use

2. UV resistant and light resistant

The textile for automobile must have good light resistance and UV resistance. The large cold and hot cycle may affect the fading and degradation of fabrics, not only the service life of the materials, but also the fabric beauty after fading. With the sun falling, the temperature inside the car decreases and greatly affects the relative humidity of the car. With the sun rising, the temperature inside the car can reach 130 ℃ under some extreme climate conditions. In order to meet the requirements of lighting and lightweight, the 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

The surface area of the front of the fabric is large, and the fog will be more serious. It will cause serious atomization due to the accumulation of chemical reagents used in the process of yarn weaving, dyeing and finishing. This problem must be strictly controlled. The surface area of the front of the fabric is large, and the fog will be more serious. If the fabric has not been fixed for a long time, the fabric will be in the form of a long stretch. Therefore, the automobile interior fabric must have certain anti atomization performance. The "rime" on the window glass is difficult to remove, which will seriously affect the sight of the passengers, and the volatile matter suspended in the air may be inhaled into the human body, thus affecting people's health and safety. These volatile substances will volatilize and condense on windows and windshield when heated, and form a phenomenon of "rime" on its surface. Therefore, the interior materials of the finished automobile may contain many low molecular volatile substances. The interior materials of the car will be sorted out before use and adhesive will be used during the installation.

4. wear resistance

The methods of testing the wear resistance of automobile textiles are Martindale method and Taber wear resistance tester. The automobile seat fabric needs to have high wear resistance, so that it can not kick off and hook the wire in the process of use to ensure the beauty of the seat. Sometimes, it may be used for more than 10 years or more, and the seat fabric is usually used for at least 2 years. Wear resistance is the most important requirement for the fabric of automobile seat and steering wheel.

5. flame retardant performance

Pay special attention to the selection. Generally speaking, the horizontal combustion test method is often used to evaluate the flame retardant performance of automobile interior materials. The thermal and combustion properties are different. The textile materials for automobile may use various fibers, their composition and chemical structure are different, so that once the car is in danger of fire, passengers can be ensured to leave or reduce the fire risk. The interior materials of automobile, especially textiles, must have good flame retardancy and flame resistance, and use flame retardant non-woven fabric.
