Two-component sound absorption and heat insulation cotton based on polypropylene superfine fibers and polyester staple fibers and preparation method thereof

Abstract

The invention relates to two-component superfine fiber material used for heat insulation and sound absorption based on polypropylene superfine fibers and polyester staple fibers and a preparation method thereof, in particular to two-component sound absorption and heat insulation cotton based on the polypropylene superfine fibers and the polyester staple fibers and a preparation method thereof. The material is specially designed for reducing noise power in a high-noise environment, and has the effects of sound absorption and heat insulation particularly in the aspects of automobiles, high speed trains and the like. The material is also suitable for the aspects of pocket-type or plate-and-frame type filters of heating and ventilating systems, household air cleaners and vacuum dust catchers, factory purification and the like. The two-component sound absorption and heat insulation cotton based on the polypropylene superfine fibers and the polyester staple fibers comprises the polypropylene superfine fibers and the polyester staple fibers, wherein the average fineness of the polypropylene superfine fibers is 1-2 micrometers, and the fineness of the polyester staple fibers is 25-35 micrometers. The two-component material formed by mixing of the polypropylene superfine fibers and the polyester staple fibers is processed through electrostatic electrets, and then the two-component sound absorption and heat insulation cotton is formed.

Description

technical field [0001] The invention relates to a two-component sound-absorbing and heat-insulating cotton based on polypropylene superfine fiber and polyester staple fiber and its preparation method, which relates to a two-component sound-absorbing and heat-insulating cotton based on polypropylene superfine fiber and polyester staple fiber. 1. Ultrafine fiber material for filtering and preparation method thereof, the material is specially designed for reducing noise energy in high-noise environments, especially in automobiles, high-speed trains, etc., and plays the role of sound absorption and heat insulation. For example: car doors, front and rear car covers, instrument panels, car beams, car driver control panel guards, roof fabric linings and other automotive interior materials. It is also suitable for bag or plate and frame filters of heating and ventilation systems, as well as household air cleaners and vacuum cleaners, and can also be used for purification of air condit...

AI Technical Summary

Problems solved by technology

[0003] Traditional textile fabrics cannot meet the thickness and hardness of materials required by the modern automobile industry, and the organizational structure cannot be evenly distributed, which greatly reduces the heat insulation and sound absorption effects

[0004] At present, the filter materials used in heating, ventilation and air conditioning systems usually use glass fiber filter materials and woven or knitted fabric filter materials made of yarn. The material has poor alkali resistance, brittleness, and is irritating to the skin
