Embodiment Construction

[0025] In order to deepen the understanding of the present invention, the present invention will be further described below in conjunction with the embodiments and accompanying drawings. The embodiments are only used to explain the present invention and do not constitute a limitation to the protection scope of the present invention.

[0026] A kind of preparation method of automobile sound-absorbing carpet as shown in Fig. 1, this carpet is formed by high-temperature pressing from top to bottom by four layers respectively A layer, B layer, C layer and D layer, wherein A layer is pile fabric layer, areal density 500g / m 2 , B layer is the bottom felt layer laid horizontally, with a surface density of 600g / m 2 , C layer is PE film, surface density is 100g / m 2 , the D layer is a PEPA asymmetric membrane with a surface density of 80g / m 2 ,

[0027] Its preparation method comprises the following steps:

[0028] a. 100% fine denier PET fibers are opened, mixed, carded, folded and...

Abstract

The invention discloses a making method of an automobile sound-absorption carpet. The carpet is formed by pressing a layer A, a layer B, a layer C and a layer D from top to bottom at high temperature. The preparation method includes the steps that a, opening, mixing, carding, cross lapping, needling forming and raising shaping are performed on 100% fine Danny PET fibers to form the layer A having excellent sound-absorption performance; b, opening, mixing, carding, cross lapping and needling forming are performed on three-dimensional crimped fibers and L-PET fibers to form the layer B having a certain thickness and a certain tightness degree; c, a three-roll hot ironing machine is used for pasting the PE face of a PEPA asymmetrical film of the layer D to the layer B, and then cooling is performed to form PET bottom felt finally; d, a PE film is used for pasting the fabric of the layer A to the face, without the PEPA asymmetrical film, of the PET bottom felt formed in the step c, so that the automobile sound-absorption carpet is formed. The automobile sound-absorption carpet has the advantage that the fine Danny fibers are adopted for achieving the sound-absorption effect of the product according to requirements.

Description

technical field [0001] The invention relates to a preparation method of a carpet, in particular to a preparation method of an automobile sound-absorbing carpet. Background technique [0002] The existing sound-absorbing products used in car main carpets are generally divided into two types: cotton felt type and PU foam type; now as the country has higher and higher air quality requirements for passenger cars, PU foam products have VOC The value of the car has remained high all the time, which seriously affects the life safety of the passengers; the sound absorption effect of the pure cotton felt type is not good. [0003] Therefore, in order to solve the above problems, a new technical solution is provided. Contents of the invention [0004] The invention provides a method for preparing an automobile sound-absorbing carpet, which is formed by laminating fine denier structure fiber fleece fabric and PET bottom felt, so that it has excellent sound-absorbing performance and ...
