Embodiment 1

[0031] At present, in the production process of non-woven fabrics, a large amount of scrap non-woven materials are produced due to cutting, and a large amount of waste non-woven materials are also produced in the process of use. The technology of interior materials is aimed at effectively utilizing non-woven waste and leftover materials to produce environmentally friendly automobile interior materials. It is used to replace non-environmentally friendly sound-absorbing layer materials for automotive interiors such as asphalt boards, glass brazing sheets, and rubber sheets. It can effectively remove moisture during the manufacturing process, and prevent the materials from mildew due to high water content during later storage and use. For example, side decoration Provide excellent drying and molding conditions for certain materials such as parts, carpet bases, wheel covers, etc. that require post-baking and compression molding.

Abstract

The invention discloses a technology for producing automotive trim materials through non-woven waste and leftover materials. The technology is characterized by comprising the following technological steps that 1, classification and impurity removal are performed on the recycled non-woven waste and leftover materials to obtain non-woven waste raw materials; 2, the non-woven waste raw materials are mixed with polyester fibers, hollow fibers and low-melt-point fibers to obtain non-woven mixed raw materials; 3, opening, combing, lapping, hot baking forming and cooling setting are sequentially performed on the non-woven mixed raw materials, and then tailoring is performed to obtain the finished products. According to the technology, the automotive trim materials which meet the specification and are environmentally friendly are produced by effectively utilizing the non-woven waste and leftover materials.

Description

technical field [0001] The invention relates to the technical field of non-woven fabric production, in particular to a process for producing automotive interior materials by using non-woven waste and leftover materials. Background technique [0002] Non-woven fabrics, also known as non-woven fabrics, are composed of directional or random fibers and are a new generation of environmentally friendly materials. Textile materials for automotive interior decoration usually have the characteristics of high strength, water repellency, breathability, flexibility, non-combustibility, non-toxic and non-irritating, and stable properties. It is non-toxic, odorless and free of any residual substances when burned, so it does not pollute the environment and is suitable for washing. It directly uses polymer chips, short fibers or filaments to form a new type of fiber product with soft, breathable and planar structure through various web forming methods and consolidation technologies. It ha...
