PURPOSE: A sound absorbing material is characterized by using polyester, forming round dots and adding inorganic powder to a silicone type binder resin. The sound absorbing material is capable of increasing workability, dissolving environmental pollution, increasing sound absorption power, preventing a slip, improving handling and construction, radiating far infrared ray, preventing mildew and a bad smell and getting fire resistance. CONSTITUTION: The polyester sound absorbing material is comprised of: 10-45wt.% of a cellulose fixing agent of polyester fiber having 3-10denier of fineness, 30-80mm of fiber length and low melting-point; 55-90wt.% of polyester fiber mixed a first polyester fiber having 10-15denier of fineness and 51-81mm of fiber length with a second polyester fiber having 3-5denier and 51-81mm of fiber length in a ratio of 1:1-1:2; and web. The sound absorbing material is obtained by forming the dots out of 80-100pts.wt. of the inorganic powder based on 100pts.wt. of the binder resin. |
