摘要： PROBLEM TO BE SOLVED: To provide soundproof fiber which is lightweight and has superior sound absorbing/proofing properties.
SOLUTION: Disclosed is a soundproof material made of a fiber structure using a fiber base body and fine powder particles stuck on the periphery of it. Silicon dioxide or activated carbon is used as the fine particle. The mean particle size of the fine powder particle is 0.1 nm to 100 μm. Soundproof fiber obtained by sticking the fine powder particle on the surface of fiber is made into non-woven fabric by a mechanical bonding method, an adhesion method, a fusing method, a wet method, etc., and the non-woven fabric is used as the fiber structure. The fiber is made into the non-woven fabric by the mechanical bonding method, adhesion method, fusing method, wet method, etc., and the fine powder particle is stuck on its surface.

摘要： PROBLEM TO BE SOLVED: To provide a piece mat for automobiles having sound absorptivity and non-permeability for water. SOLUTION: A non-water permeable foam sheet including an activating agent to increase the dipole moment is joined in discontinuity to the rear surface of a drafty facial material layer 21 of a gray fabric of tuft carpet, needle carpet, etc. using polyethylene powder, ethylene vinyl acetate resin powder, low melting point fiber web, emulsion binder, and a hot-melt adhesive. Also a non-slip unwoven cloth for precluding slip with a floor laying material 1 is joined in discontinuity. COPYRIGHT: (C)2005,JPO&NCIPI
