The invention relates to a composite fiber felt and a preparation method thereof, an automobile trunk protection face and an automobile. The composite fiber felt comprises a body layer, and the body layer is prepared from, by weight, 25%-70% of natural fibers, 25%-70% of noctilucent polypropylene fibers and 5%-15% of low-melting-point fibers; the diameter of the natural fibers ranges from 9 micrometers to 17 micrometers, and the length of the natural fibers ranges from 50 mm to 150 mm. The diameter of the noctilucent polypropylene fiber ranges from 20 micrometers to 48 micrometers, and the length of the noctilucent polypropylene fiber ranges from 50 mm to 150 mm. According to the composite fiber felt, the preparation raw materials of the body layer are controlled in a specific proportion, and the diameters and lengths of the natural fibers and the noctilucent polypropylene fibers are in a specific range, so that the prepared composite fiber felt has relatively low density and better rigidity, tensile strength and bending modulus, the supporting performance of the composite fiber felt can be improved while the weight is reduced, and the service life of the composite fiber felt is prolonged. And meanwhile, a noctilucent function is achieved.
本申请涉及一种复合纤维毡及其制备方法、汽车行李箱护面和汽车。该复合纤维毡包括本体层,本体层的制备原料按照重量百分含量计,包括天然纤维25%~70%、夜光丙纶纤维25%~70%以及低熔点纤维5%~15%;天然纤维的直径为9μm~17μm,天然纤维的长度为50mm~150mm;夜光丙纶纤维的直径为20μm~48μm,夜光丙纶纤维的长度为50mm~150mm。上述复合纤维毡中控制本体层的制备原料在特定比例、上述天然纤维和夜光丙纶纤维的直径和长度在特定范围,从而使制得的复合纤维毡具有较低的密度、更好的刚性、拉伸强度和弯曲模量,故而可在轻量化的同时提升其支撑性能,同时兼顾夜光功能。
