Problems solved by technology

[0003] Compared with the rapid development of the automobile industry, the current development status of nonwoven materials for vehicles in my country is not optimistic. The most prominent performance is that most of my country's high-performance chemical fiber raw materials, composite materials for automobiles, and high-end nonwoven materials for vehicles The parts are mainly imported, and the new product development capabilities of domestic enterprises are relatively weak; moreover, automotive nonwoven materials have high requirements on fabric functionality, and must have fiber strength indicators, hygroscopicity, air permeability, color fastness, and sunlight resistance. , cleaning resistance, flame retardancy, anti-static, anti-lint, recyclable, antibacterial and more than a dozen functions, the production is difficult

Abstract

The invention belongs to automotive non-woven textiles, in particular to an environmentally friendly differential fiber non-woven automotive interior trim material and a preparation method thereof. The preparation method comprises the following steps of: preparing needle-punched grey cloth through feeding fibers, roughly opening, mixing fibers, fine opening, carding the fibers into a net, crosswise spreading the net and needling by using environmentally friendly colored flame retardant terylene short fibers as a raw material; and then carrying out foam gum dipping in flame retardant polyacrylate foaming rubber latex to obtain the differential fiber non-woven automotive interior trim material, wherein the adhesion quantity of the rubber latex is controlled to be 12-18g / m<2>. The environmentally friendly differential fiber non-woven automotive interior trim material has good property, high quality, environmental protection and high safety; and the preparation method provided by the invention has low energy consumption, no pollution and low cost.

Description

technical field [0001] The invention belongs to nonwoven textiles for automobiles, in particular to an environment-friendly differential fiber nonwoven automobile interior decoration material and a preparation method thereof. Background technique [0002] Since entering the 21st century, the world's automobile industry has undergone earth-shaking changes, and its development is extremely rapid. The rapid development of the automobile industry has driven the application of automotive textiles. Among them, non-woven fabrics account for an increasing proportion. In the entire car structure, textiles can account for 3% of the total weight of the car. On average, 1 ton of cars will use 30 kg of textiles, of which 2 / 3 are non-woven fabrics. Weaving cloth; China is the country with the most rapid development of the automobile industry in the world. In recent years, the production of automobiles has increased year by year. In 2007, the sales volume reached 8 million. In 2007, the ...
