The invention provides a coconut hemp mixed fiber composite material for an automotive interior material and a preparation method thereof, and belongs to the technical field of automotive interior materials. The coconut and hemp mixed fiber composite material for the automotive trim material comprises a coconut and hemp mixed fiber felt layer, wherein the coconut and hemp mixed fiber felt layer is formed by opening, scattering, fully mixing and carding mixed fibers of coconut fibers and hemp fibers and oil/oil-free polypropylene short fibers to form a fiber net which is hooked together, and then needling the fiber net into a dense felt material. The coconut and hemp mixed fiber composite material produced from the coconut and hemp mixed fibers and the oiled/oil-free polypropylene short fibers, provided by the invention, is corrosion-resistant, mildew-proof, antibacterial, breathable and high in cost performance, and compared with a composite material produced from hemp fibers and common polypropylene short fibers, the coconut and hemp mixed fiber composite material is harmless to a human body and has remarkable advantages in the aspect of odor.

    本发明提供了一种用于汽车内饰材料的椰麻混合纤维复合材料及其制备方法,属于汽车内饰材料技术领域。本发明提供的用于汽车内饰材料的椰麻混合纤维复合材料包括椰麻混合纤维毡层;其中,所述椰麻混合纤维毡层为椰棕纤维和麻纤维的混合纤维与有油/无油聚丙烯短纤维经开松、打散、充分混合梳理形成互相勾连在一起的纤维网后,通过针刺为密实毡材而成。本发明提供的用椰麻混合纤维与有油/无油聚丙烯短纤维生产所得的椰麻混合纤维复合材料防腐、不霉变、抗菌、透气,并且性价比高,相比用麻纤维与普通聚丙烯短纤维生产的复合材料而言,对人体无害且在气味方面具有显著优势。
