Definitions
- a muffler aiming at sound reduction of exhaust gas is arranged in an exhaust system of an internal combustion engine of an automobile.
- an object of the present invention is to provide a sound absorbing material which is superior in acid resistance, alkali resistance and sound absorbing qualities, a muffler using this sound absorbing material, and a method for forming a sound absorbing layer of the muffler.
- the sound absorbing material 2 is wound around a perforated pipe of the muffler.
- the bundled material is supplied into the nozzle while blowing the compressed air into the nozzle, and the bundled material is unraveled by the compressed air to form the continuously fibrillated sound absorbing material from the nozzle, thereby readily and continuously performing the above fibrillation.
