PURPOSE: An adhesive low melting point staple fiber and an inter-fiber attachment method using the same are provided to conduct the attachment operation in simplified and stable manners without generating any pollutant. CONSTITUTION: In a method of preparing a heat insulator or an acoustic absorbent, an adhesive staple fiber(10) bearing a low melting point of 60-90 deg.C is interposed between the respective fibers(1), such as non-woven fabrics, to make a fiber structure, and the fiber structure passes through heating rollers(2) such that the adhesive staple fiber is melt under the application of the heat of 60-90 deg.C to make the desired attachment. The low melting point staple fiber is prepared by adding vinyl chloride to polypropylene in a ratio of 50:50 to produce a staple fiber, and punching the staple fiber such that the staple fiber bears a predetermined cushion and a predetermined thickness. |
