Problems solved by technology

However, since the sound absorption coefficient of non-woven fabrics for automotive interiors is often less than 0.2, the current non-woven fabrics for automotive interiors do not have the problem of absorbing the noise generated during the running of the car. The various frequency noises in the car cannot provide a quiet environment. The driving and riding environment has increased the occurrence of traffic accidents caused by fatigue driving due to car noise, so car noise bothers people to drive safely

Abstract

The invention discloses a nonwoven fabric composite sound-absorbing lamination fabric for automobile internal decoration and a manufacturing method thereof. The sound-absorbing lamination fabric comprises a micropore sound-absorbing thin film layer, a connecting layer and an automobile internal decoration nonwoven fabric layer. The manufacturing method comprises the steps: unwinding the automobile internal decoration nonwoven fabric layer and the micropore sound-absorbing thin film layer, arranging the connecting layer on the micropore sound-absorbing thin film layer, laminating the micropore sound-absorbing thin film layer on at least one surface of the automobile internal decoration nonwoven fabric layer through the connecting layer for composite, carrying out hot-pressing, winding, carrying out room temperature ripening, unwinding, carrying out edge cutting and shunt winding, inspecting, and packing. According to the above method, the sound-absorbing lamination fabric can obviously absorb various frequency noises inside an automobile, greatly reduces the automobile internal noise value, gives a person a quiet driving and riding environment, and allows occurrence of traffic accidents caused by fatigue driving due to the automobile noises to be greatly reduced. The novel fabric is allowed to have more significant and remarkable sound-absorbing function, and allows an only beauty decorating effect of a conventional automobile internal decoration nonwoven fabric to be changed.

Description

Technical field [0001] The invention relates to the field of sound-absorbing laminated fabrics, in particular to a sound-absorbing laminated fabric composed of nonwoven fabrics for automobile interior decoration and a manufacturing method thereof. Background technique [0002] The application of non-woven fabrics in automobiles is increasing. As a new type of textile, non-woven fabrics have won a due market for themselves with their lower production costs and excellent performance. They have completely replaced or even surpassed them in many industrial applications. Traditional woven and knitted fabrics. In automobiles, non-woven fabrics can meet the needs of different uses. Each foreign car consumes 20m 2 The left and right non-woven fabrics include cushioning materials, covering materials, filter materials, etc. And the number of applications of non-woven fabrics in automobiles is increasing. According to incomplete statistics, the number of non-woven fabrics used in the autom...
