MANUFACTURING METHOD OF NON-WOVEN FABRIC FOR SOUND ABSORPTION MATERIAL OR HEAT INSULATION MATERIAL, AND NON-WOVEN FABRIC FOR SOUND ABSORPTION MATERIAL OR HEAT INSULATION MATERIAL
To provide an easily weight-savable non-woven fabric for a sound absorption material or a heat insulation material, capable of striking balance between excellent sound absorption property and powder fall prevention; and to provide a manufacturing method of them.SOLUTION: In a manufacturing method of a non-woven fabric for a sound absorption material or a heat insulation material, coating liquid containing thermal expansion particles is impregnated into a non-woven fabric base material formed by blending non-woven fabric base material fibers with fibers having a lower melting point than the non-woven fabric base material fibers, followed by thermobonding thereof, then a thickness of the non-woven fabric base material is adjusted to be 5 mm or more by expanding the thermal expansion particles, and on the other hand, the content of the thermal expansion particles after expansion is adjusted to be 20 g/mor less.SELECTED DRAWING: None
【課題】本発明は、軽量化が容易であり、優れた吸音特性と粉落ち防止とを両立し得る吸音材用又は断熱材用不織布、及びそれらの製造方法を提供する。【解決手段】不織布基材繊維と、前記不織布基材繊維よりも融点の低い繊維とを混綿して熱接着した不織布基材に、熱膨張性微粒子を含む塗布液を含浸し、前記熱膨張性微粒子を膨張させて前記不織布基材の厚さを5mm以上にする一方、前記熱膨張性微粒子の膨張後の含有量を20g/m2以下とすることを特徴とする吸音材用又は断熱材用不織布の製造方法。【選択図】なし
