Abstract:
A waved meltblown fiber web of the present invention relates to a fiber web prepared by a meltblown method and is characterized by a preparation method in which a meltblown microfiber comes in contact with collection portions having different surface velocities so as to be collected. The waved meltblown fiber web of the present invention is characterized in that: a part of meltblown microfibers reaches a low velocity collection portion so as to be horizontally layered, thereby forming a horizontal fiber layer ( 10 ); another part of the meltblown microfibers reaches a high velocity collection portion of which the surface velocity is greater that of the low velocity collection portion so as to form a serpentine vertical fiber layer ( 20 ); and the upper end of the vertical fiber layer ( 20 ) becomes entangled so as to form a wave shaped wave layer ( 30 ) forming the uppermost portion of the fiber web.

Claim (Index 1):
A method of absorbing sound comprising incorporating a waved meltblown fiber web into sound insulation or soundproofing material,\n wherein the waved meltblown fiber web is produced by a melt-blown method, and comprises a horizontal fiber layer, a vertical fiber layer formed on the horizontal fiber layer, and a waved layer forming an uppermost portion of the vertical fiber layer the horizontal fiber layer is formed by allowing a portion of meltblown microfibers to reach a low-velocity collection portion and to be deposited on the low-velocity collection portion in a horizontal orientation hereby the microfibers are in a horizontal orientation; the vertical fiber layer is formed in a serpentine shape of vertically oriented microfibers and deposited on the horizontal fiber layer after the horizontal fiber layer is deposited, by allowing the other portion of the meltblown microfibers to reach a high-velocity collection portion having a surface velocity higher than that of the low-velocity collection portion; and the waved layer is formed by entanglement of the microfibers at a top of the vertical fiber layer and forms the uppermost portion of the fiber web; the horizontal fiber layer and the vertical fiber layer being present in thicknesses such that a ratio of the thickness of the horizontal fiber layer to the thickness of the vertical fiber layer being 1:1 to 1:9 in a state in which no external compressive load is applied to the fiber web and the fiber web is freely spread out, or in a state in which no external compressive load is applied to the fiber web and the fiber web is covered with a covering fabric and is freely spread out, or in a state in which the fiber web is pulled up upwardly by an external force by 0.1-2 times the total thickness of the fiber web in a load-free state; wherein 70% to 90% of the meltblown microfibers have a diameter of 10 \u03bcm or less and 10% to 30% of the meltblown microfibers have a diameter of 3 \u03bcm or less; and wherein the waved meltblown fiber web is capable of absorbing sound ranging from 400 Hz to 10,000 Hz.
