Non-woven fabric as auto interior materials which need to be standard

Now many materials of automobile interior trim is made use of non-woven fabric, such as car roof, car MATS, car interior decorative plate etc are made of non-woven fabric, so as the car interior, non-woven fabric needs to have the time requirements, we sum up the total of four below for everyone to understand. 1. Breathable moisture acupuncture non-woven fabrics are used for car interior, is on the low-standard cars, general with the camry this level as the boundary. Acupuncture and lockstitch, generally belongs to the low and medium car use, limousine with woven, ceiling molding also will add spun-bonded non-woven fabric reinforcement. Has two kinds of non-woven fabric and knitting. Non-woven fabric is: acupuncture, stitch-bonded ( Mainly horsepower vries sewing weaving cloth) , see you in the fabric or the ceiling. In high-grade material, now more and more models to switch to this kind of material, no yarn seam roof: polyester material, the coil structure, with warp knitting alike, characteristics also lies in the thickness direction has good elasticity. Acupuncture ceiling: polyester materials, the effect is fuzzy, the price is cheap, a lot of cars, vans in 2. Uv light automotive textiles must have good light resistance and uv resistance. Big psychro-thermal cycles may affect the fabric fading and degradation, not only affect the service life of the material, and fade textiles will greatly influence the fabric after beautiful sex. As the land of the sun, the car temperature drop and greatly influence the relative humidity of the compartment. As the sun rises, in certain extreme weather conditions, the inside temperature can reach 130 ℃. Modern cars in order to meet the requirements of lighting and auto lightweight, window glass began to occupy large area, resulting in car interior space will be affected by light. 3. Atomization performance velvet fabric fiber surface area is large, positive rime phenomenon is more serious, because the yarn weaving, dyeing and finishing process of chemical reagents used in the accumulation and severe atomization, the problem must be strictly controlled. Velvet fabric fiber surface area is large, positive rime phenomenon is more serious, if the fabric not stenter setting for a long time. Therefore, car interior fabric must have certain atomization resistance. 'Rime on the window glass' it is difficult to remove, will seriously affect the company by personnel in the line of sight, and volatile matter suspended in the air may be drawn into the human body, then affects people's health and safety. The volatile matter in heated evaporates when condensation on the Windows and windshield, forming a 'rime' phenomenon on the surface. So the finished car interior materials may contain many low molecular volatile matter. Auto interior materials before use through a variety of functions, and adhesives are used during the installation process. 4. Abrasion resistance for automotive textiles wear-resisting performance test methods of common martindale method and taber abrasion tester and so on. Car seat fabric need has high wear resistance, can't afford to make it in use process, not hook wire to ensure the beautiful sex of seats. Some of the time, it may use more than 10 years or longer, the seat fabric in general to use at least 2 years of time. Wear resistance is the most important for car seat fabrics and fabrics of the steering wheel. 5. Flame retardant performance when the choice to pay special attention to. In general, commonly used by the method of horizontal burning test, auto interior materials of the flame retardant performance evaluation. The combustion properties and thermal properties are different. Automobile textile material may be used in all kinds of fiber, their composition and chemical structure of each are not identical, so that once the car after the fire danger can ensure passengers have plenty of time to leave, or reduce the occurrence of fire danger. Car interior materials especially textiles must want to have a good flammability and flame retardant, flame retardant non-woven fabrics.
