The colors (patterns) of the interior fabrics are completed through processes such as dyeing and printing. The dyeing fastness requirements for automotive seat fabrics include fastness to sunlight, fastness to water immersion, fastness to sweat, and fastness to rubbing. Due to the large inclination of the front windshield of the car, the car seat should be exposed to the sun for a long time, and the seat textile should have good fastness to sunlight. Due to the large contact area between the driver and the passenger for a long time, they may be eroded by sweat and may be immersed in water. Therefore, good fastness to rubbing, fastness to perspiration, and fastness to water immersion should become the basic requirements for automotive seat fabrics.

Car decorative fabric is fixed in the car, often accompanied by the life of the car. Car seat covers are not washed as often as clothing, so the anti-stain performance of fabrics in cars has attracted much attention. Fluorine-containing fabric finishing agents show advantages not available in ordinary hydrocarbon or silicone waterproofing agents, and have become the mainstream of today's waterproof and oil-repellent agents. And multifunctionalization has become an inevitable trend of the development of this type of finishing agent, that is, the fabric treated with the fluorine-containing finishing agent not only has water and oil resistance, but also has antifouling, decontamination, antistatic, dry cleaning, and washing resistance. Multiple characteristics.

Since the price of fluorine-containing finishing agents is much more expensive than general fabric finishing agents, this has greatly affected its development. Mixing fluorine-containing finishing agents with other types of finishing agents and producing durable washing resistance can not only improve product performance, but also reduce production costs.

The static phenomenon of functional fabrics in automobiles is a problem that cannot be ignored. First of all, static electricity will make passengers (especially when wearing chemical fiber clothing) feel uncomfortable, and a frictional discharge phenomenon will occur when leaving the seat. The driver's electrostatic beaters are likely to cause secondary accidents. Secondly, the electrostatic charge accumulates on the fiber surface and easily adsorbs dust, which causes a lot of trouble for cleaning and maintenance inside the car. In addition, gasoline vapor or smoke generated from smoking may be present in the car, which is likely to cause a fire under the action of static electricity. At the same time, static electricity can reduce the sensitivity of electronic components in the car.

Antistatic finishing of synthetic fiber fabrics for automotive interiors is more mobile and flexible than antistatic methods such as chemical modification from polymerization and blending from spinning. And the processing flow is short. Less investment in industrialization, quick results.
