PURPOSE:To make improvements in the permeability and sound-absorbability of a trimming outer layer material by impregnating resin on the opposite side to the needling surface of a needle punched nonwoven fabric, needling one side of a fiber web containing a specified quantity of a thermoadhesive composite fiber, and applying printed finish and embossing finish on the surface. CONSTITUTION:Needling is applied to a fiber web made up of blending a composite fiber such a core-sheath type polyester thermoadhesive fiber as much as 5-25wt.% from one side, thereby forming a needling punched nonwoven fabric. Next, urethane resin emulsion is impregnated on a surface where needling is not applied so as to cause it to become about 15g/m<2> in solid quantity, and acrylic resin is printed on this surface in leather-drawing pattern form so as to cause its sticking quantity to become about 10g/m<2>. Then, embossing finish is applied to this surface with a leather-drawing pattern embossing roll and it is made so as to cause its aeration degree to becomes 50-120cc/cm<2>/sec. An outer layer material obtained like this is excellent in permeability and sound-absorbability, and it is light in weight and, also has a soft and warm feeling. |
