Non-woven composite material with sound absorption function

Abstract

The invention discloses a non-woven composite material with sound absorption function. The main components comprise terylene staple fiber and hollow staple fiber as well as low-melting fiber, whereinthe terylene staple fiber accounts for 20-40% of the total weight of the components, the hollow staple fiber accounts for 10-30% of the total weight of the components, and the low-melting fiber accounts for 48-52% of the total weight of the components. The non-woven composite material with sound absorption function of the invention has the advantages of good sound absorption performance, no toxicity and no pollution.

Description

technical field [0001] The invention relates to a non-woven composite material, in particular to a non-woven composite material with sound-absorbing function. Background technique [0002] Non-woven composite material, also known as non-woven fabric in the industry, is composed of oriented or random fibers. It is a new material with good strength, breathable and waterproof, environmentally friendly, flexible, non-toxic and tasteless, and cheap Etc. It is a new generation of environmentally friendly materials, with the characteristics of water repellency, breathability, flexibility, non-combustibility, non-toxic and non-irritating, and rich colors. If the material is naturally decomposed outdoors, its longest lifespan is only 90 days, and it decomposes within 8 years when placed indoors. It is non-toxic, tasteless, and free of any remaining substances when burned, so it does not pollute the environment. [0003] In addition, non-woven fabrics also have the effect of sound i...

However, the sound insulation effect of non-woven sound insulation products on the market is not ideal

The applicant believes that the main reason is that polypropylene yarn is used as the adhesive of the product. Since the oxidation temperature of polypropylene yarn is relatively high, about 180°C, this temperature directly leads to the oxidation and decomposition of the fiber itself, thus affecting the sound insulation performance of the material.
