    摘要： The present invention provides an electret nonwoven web useable in a variety of applications. The nonwoven web is prepared from continuous fibers and once formed, a binder composition is applied to the nonwoven web. Generally the binder composition is sprayed on or impregnated into the nonwoven web and the binder composition is cured forming a nonwoven web/binder composite material. After the binder composition is cured, the composite is electret charged. The application of the binder composition to the nonwoven web provides the nonwoven web with stiffness and with characteristics such that it can be pleated and such pleats can be retained without the use of a supporting substrate. This makes the electret charged nonwoven web highly suitable and cost effective for filter media by eliminating the need for laminating the media to a supporting member.

    摘要： The present invention relates an acoustical insulation material for sound attenuation containing a nonwoven web. Surprisingly, it has been discovered that an acoustical insulation material made from a nonwoven web of thermoplastic fibers having an average fiber diameter of less than about 7 microns, wherein the acoustical insulation has a thickness less than about 3 mm and a density of greater than about 50 kg/m3 is effective as a sound insulation material. The acoustical insulation is very effective as an acoustical insulation material, despite the low thickness and high density of the acoustical insulation. A method of attenuating sound waves passing from a sound source area to a second area using the acoustical insulation material is also disclosed.
