Abstract

The invention relates to a preparation method of a backrest carpet part for an automobile. The backrest carpet part comprises a napping fabric layer, a bonding layer and a base layer felt which are sequentially arranged from top to bottom. The preparation method comprises the following steps: preparing the napping fabric layer, preparing the base layer felt, compounding the napping fabric layer and the base layer felt, napping and needling and forming the carpet part, wherein napping and needling are characterized in that the composite material is subjected to needling napping on one surface of the surface layer of the napping fabric layer through main needling to process the surface layer with fluff to obtain the composite carpet; in the napping and needling process, fibers of the nappingfabric layer are pulled out through a fork-shaped needle, the pulled-out fibers are clamped and kept through bristles of a napping brush, fluff with the length ranging from 3 mm to 4 mm appears on the surface of the carpet and the needling density is 495 +/-25 c/cm < 2 > * min. Compared with the methods in the prior art, the backrest carpet part has the advantages of attractive product surface quality, compact structure, simple process, low influence on the environment and the like.

Description

technical field [0001] The invention relates to a method for manufacturing various automobile parts, in particular to a method for preparing a backrest carpet part for automobiles. Background technique [0002] The backrest carpet is made by molding and is mainly installed in the backrest area of ​​the car seat. Its main function is to cover the sheet metal, play the role of shock absorption, decoration, beauty and comfort. The integration of the surface carpet and the felt embryo is now used to replace the previous production process of spraying rubber powder on the felt embryo and attaching the surface carpet to improve the quality of the car interior, the interior environment and VOC requirements. For example, Chinese patent CN 104108218 A discloses a composite formable carpet and a manufacturing method thereof. The manufacturing method includes the following steps: A. Opening, mixing, carding, and netting the fiber raw materials according to a preset ratio to form a uni...
