Embodiment Construction
[0021] Refer to attached figure 1 The composition of the two-component sound-absorbing and heat-insulating cotton based on polypropylene superfine fiber and polyester staple fiber includes polypropylene superfine fiber and polyester staple fiber, wherein the average fineness of polypropylene fiber is 1-2 μm, and the polyester staple fiber The fineness is 25-35μm. The two-component material mixed with these two components is subjected to electrostatic electret to form a two-component sound-absorbing and heat-insulating cotton. The electrostatic electret voltage is 50-70KV.
[0022] The content of the polypropylene superfine fiber accounts for 65%-80% of the whole sound-absorbing and heat-insulating cotton.
[0023] The mass ratio of the polypropylene superfine fiber and polyester staple fiber is 70:30.
[0024] The preparation method of the two-component sound-absorbing and heat-insulating cotton based on polypropylene microfiber and polyester staple fiber is as follows:
