How to detect the wear resistance of leather interior materials

1. Fire retardant performance 94dTextile Testing Instruments, Testing Equipment Manufacturer

Automotive interior materials, especially textiles, must have good flames and flame retardability. In this way, once the car is in danger, it can ensure that passengers have enough time to leave, or reduce the risk of fire. Various fibers may be used in vehicle textile materials. Their composition is different from the chemical structure, and their thermal performance and combustion performance are also different. Pay special attention when choosing. Generally speaking, the combustion test method is commonly used to evaluate the flame retardant performance of car interior materials. 94dTextile Testing Instruments, Testing Equipment Manufacturer

2. Abrasion resistance 94dTextile Testing Instruments, Testing Equipment Manufacturer

wear resistance is the most important requirement for car seat fabrics and steering wheel fabrics. The seat fabric generally uses at least 2 years, and some time may be used for more than 10 years or even longer. Therefore, the car seat fabric needs to have high wear resistance, so that it cannot afford it during the use process. Balls and no hooks to ensure the aesthetics of the seat. Martin Delfa and Taber wear -resistant test machines are common for testing methods for wear -resistant performances for vehicle textiles. 94dTextile Testing Instruments, Testing Equipment Manufacturer

3. Atomizing performance 94dTextile Testing Instruments, Testing Equipment Manufacturer

The car interior material will be organized by various functions before use, and adhesives will be used during the installation process, so finished products The car interior material may contain many low -molecules of hair waves. These volatile objects will volatilize on the window and windshield when heated, forming a fog phenomenon on its surface. The fog on the window glass is difficult to remove, which will seriously affect the attention of the staff, and the volatile objects suspended in the air may be inhaled into the human body, which will affect people's health and safety. Therefore, the car interior fabric must have a certain resistance. If the fabric is fixed for a long time, it will be severely atomized due to the accumulation of chemical reagents used in the yarn weaving, dyeing and post -finishing process. This problem must be strictly controlled. The fiber surface area of the velvet fabric is large, and the phenomenon of fog will be more serious. 94dTextile Testing Instruments, Testing Equipment Manufacturer

4. Light resistance and ultraviolet performance 94dTextile Testing Instruments, Testing Equipment Manufacturer

In order to meet the requirements of lighting and car lightweight in modern cars, window glass began to occupy a large amount Space will be affected by light. As the sun rises, under certain extreme climate conditions, the temperature inside the carriage can reach 130 ° C; as the sun falls, the temperature in the car decreases and greatly affects the relative humidity of the carriage. Such a large hot and cold cycle may affect the fading and degradation of the fabric, which not only affects the service life of the material, but also greatly affects the aesthetics of the fabric after the fading of textiles. Therefore, it is required to have good optical resistance and anti -ultraviolet performance. 94dTextile Testing Instruments, Testing Equipment Manufacturer

Textile materials will cause degradation under the action of ultraviolet radiation and humidity. Natural fiber's anti -ultraviolet performance is poor, cotton fabrics have the worst anti -ultraviolet effects, and wool anti -ultraviolet performance is slightly better. The anti -ultraviolet performance of synthetic fibers is generally better than heavenHowever, the anti -ultraviolet performance of fiber, polyester, and acrylic fibers is better, and the abrasion resistance of acrylics is slightly poor. Therefore, there are not many actual applications. The polyester anti -ultraviolet resistance is the best, and it has good abrasion resistance.EssenceIn order to improve the anti -ultraviolet and light resistance of car interior fabrics, it is necessary to use the interior fabric to resist ultraviolet arrangement to reduce the degradation of the interior fabric and extend the service life of the product.94dTextile Testing Instruments, Testing Equipment Manufacturer

In addition, the car interior material should also have good self -cleaning properties, good dyeing firmness, and other performances such as the self -cleaning properties of water and oil and refusal.94dTextile Testing Instruments, Testing Equipment Manufacturer
