Car carpet with enhanced sound insulation

Abstract

The invention provides an automobile carpet capable of enhancing sound insulation. The automobile carpet comprises a PET / PP (Polyethylene Terephthalate / Polypropene) composite layer, wherein a PE film layer is arranged on the front surface of the PET / PP composite layer; a PP film layer is arranged on the back surface of the PET / PP composite layer; a PET fabric layer is arranged on the front surface of the PE film layer; a PET non-woven fabric layer is arranged on the back surface of the PP film layer; an antistatic layer is arranged on the front surface of the PET fabric layer; an anti-sliding layer is arranged on the back surface of the PET non-woven fabric layer; anti-sliding lines are arranged on the anti-sliding layer; and a waterproof and ventilated layer is arranged on the front surface of the antistatic layer. The invention further provides a manufacturing method of the automobile carpet capable of enhancing sound insulation; the automobile carpet capable of enhancing sound insulation, provided by the invention, has excellent sound insulation and strength; sound absorption and sound insulation are combined so that inner noises of an automobile are effectively reduced; furthermore, the automobile carpet capable of enhancing sound insulation, provided by the invention, has very light weight and also has a good anti-sliding effect; and the antistatic performance and the waterproof and ventilated performance of the carpet are enhanced on the basis.

Description

technical field [0001] The invention relates to a carpet and a manufacturing method thereof, in particular to a car carpet with enhanced sound insulation and a manufacturing method thereof. Background technique [0002] Carpet is a floor covering made of cotton, linen, wool, silk, grass and other natural fibers or chemical synthetic fiber materials, which are knitted, tufted or woven by hand or mechanically. It is one of the arts and crafts categories with a long history and tradition in the world.

AI Technical Summary

Problems solved by technology

[0005] Existing car carpets are generally divided into two types, one is a PET needle-punched fabric and a layer of PE film between the bottom felt for decoration and sound insulation, which is cheap, but the sound insulation effect is poor with only one layer of PE film; One is a heavy coating between the PET needle-punched fabric and the bottom felt, which has a good sound insulation effect, but the product has high weight and high cost, and does not meet the lightweight requirements of automobiles.
