Abstract

The invention discloses intercalated melt-blown sound-absorbing cotton and a preparation method thereof. The intercalated melt-blown sound-absorbing cotton comprises hollow polyester staple fibers, high-modulus staple fibers and a melt-blown polypropylene fiber intercalation, wherein the mass ratio of the melt-blown polypropylene fibers to the total mass of the hollow polyester staple fibers and the high-modulus staple fibers is (1.5-8.0): 1; the mass ratio of the hollow polyester staple fibers to the high-modulus staple fibers is (4.0-20): 1. According to the preparation method, the hollow polyester staple fibers, the high-modulus staple fibers and the melt-blown polypropylene fibers are subjected to intercalation compounding, and the porosity, the fiber fineness and the structure of the sound-absorbing cotton are controlled by controlling the types and the proportions of the fibers, so that the intercalated melt-blown sound-absorbing cotton with high compression resilience and a good sound-absorbing effect is obtained.
