Problems solved by technology

However, traditional base materials are generally woven polyester fiber nets, or thin-weight non-woven materials that are needle-punched and reinforced with PET or PP, which not only do not have the function of sound absorption and noise reduction, but also do not have a good flame retardant effect. poor environmental friendliness

Abstract

The invention discloses a production process for a new sound absorption and noise reduction automotive interior spunlace non-woven material and belongs to the technical field of textile materials. Acetate fibers are adopted as raw materials and are sequentially fed into a long curtain, a horizontal type opener and a large-bin cotton blending box; then, layering processing is conducted through a first fine opener and a second fine opener, the raw materials processed by the first fine opener are sequentially fed into a first cotton storage box, a first airflow cotton box, a first carding machine, a cross lapping machine and a drafting machine, and the raw materials processed by the second fine opener are sequentially fed into a second cotton storage box, a second airflow cotton box and a second carding machine; the two layers of the raw materials are overlapped and sequentially subjected to the spunlace procedure, the drying procedure, the online detecting procedure and the take-up procedure. The new sound absorption and noise reduction automotive interior spunlace non-woven material is good in sound absorption effect, high in flame retardancy and degradable.

Description

technical field [0001] The invention discloses a production process of a new spunlace nonwoven material for sound-absorbing and noise-reducing automobile interior decoration, and belongs to the technical field of textile materials. Background technique [0002] The automobile industry has the characteristics of obvious technology-intensive, capital-intensive, comprehensive performance, high added value, and good economic benefits. The automobile industry is closely related to social production. The development of automobile production can drive a large number of parts manufacturers and raw material industries. The development of the country has a huge driving effect on the entire social economy. Parts are estimated to account for more than two-thirds of a car's total value. Automobiles are high-value-added products with deep processing, high value-added, and higher labor productivity than other products. The international market value of automobiles has exceeded US$100 ...
