What aspects should be tested for interior circulation materials?

With the rapid development of the automotive industry and the adjustment of the structure of the textile industry, textiles, especially functional textiles, have very broad prospects in the automotive market. On the one hand, interior decoration of automobiles, seat belts, airbags, seat cushions and car mats, ceiling materials and curtains, etc., as well as textiles are ubiquitous in the materials of reinforcement, noise control and gas filtration; on the other hand, the performance of automotive interior materials is also increasingly influencing today\'s consumer choices for better products.

Due to its use environment, use characteristics, environmental protection and safety considerations, the textAutomotive interior materials generally meet the following basic requirements:

1. Flame-retardant properties

Automotive interior materials, especially textiles, must have good flame retardancy and flame retardance. In this way, passengers can be assured of having sufficient time to leave once a fire hazard occurs in the car, or the occurrence of a fire hazard can be reduced. A variety of fibers can be used in automotive textile materials, with different chemical compositions and structures, as well as different thermal and combustion properties. Pay special attention when choosing. Generally speaking, the horizontal combustion test method is commonly used to evaluate the flame retardancy of automobile interior materials.

2. Atomization performance

MaterialsAutomobile interiors will be sorted according to various functions before use and after installation, adhesives are used in the process, so the finished car interior materials may contain many low molecular weight volatile compounds, which evaporate when heated and condense on windows and windshields, forming a \"frost\" phenomenon. The \"frost\" on the glass is difficult to remove, which will seriously affect the eyesight of drivers and passengers, and airborne volatile substances can be inhaled into the human body, thereby affecting health and safety people. Therefore, automotive interior fabrics must have certain anti-fog properties. If the fabric has not been stretched for a long time, it will cause heavy fogging due to the build-up of chemical agents used in the process of weaving, dyeing and finishing the yarn.This problem must be strictly controlled. The surface area of ​​the fibers on the front of the velvet fabric is large and the fogging phenomenon will be more serious.

3. Resistance to abrasion

Resistance to abrasion is the most important requirement for car seat fabrics and steering wheel fabrics. Seat fabrics generally need to be used for at least 2 years, and sometimes they can be used for more than 10 years or even longer. Therefore, car seat fabrics must have high wear resistance so as not to be damaged during use. Ball, no snagging to the eEnsure the seatThe aesthetics of the chair. Common testing methods for abrasion resistance of automotive textiles include Martindale method and Taber abrasion tester, etc.

4. Light fastness and UV resistance

In modern cars, in order to meet the demandsnces of lighting and lightness, the glass window surface began to occupy a lot of space, which affected the interior space of the car by light. At sunrise, in certain extreme weather conditions, the temperature inside the car can reach 130°C; As the sun sets, the temperature inside the car drops, which greatly affects the relative humidity of the car. Such a large hot and cold cycle can affect the fading and degradation of the fabric, which not only affects the life of the material, but also greatly affects the aesthetics of the fabric after fading. Therefore, automotive textiles must have good light and UV resistance.

Textile materialMetals will degrade under the action of prolonged exposure to ultraviolet rays, humidity and heat. Natural fibers have low UV resistance, fabrics in ccotton have the worst UV resistance and wool has slightly better UV resistance. The UV resistance of synthetic fibers is generally better than that of natural fibers. Polyester and acrylic fibers have better UV resistance. Acrylic fibers have slightly worse wear resistance, so they are not widely used in practical applications. Polyester has the best UV resistance and has good wear resistance, more practical applications. In order to improve the UV and light resistance of automobile interior fabrics, it is necessary to perform anti-UV finishing on automobile interior fabrics to reduce the degradation of interior fabrics and prolong the service life. life of the product.
