Polyester fiber sound-absorbing
cotton (cotton insulation) internal fiber fleeciness crisscross,
there are lots of tiny pore, is a typical porous sound-absorbing
material, has good sound-absorbing properties. Polyester fiber
sound-absorbing cotton (cotton insulation) can be made into
wallboard, ceiling, and other sound-absorbing body, can be
absorbed in a room acoustic energy, reduce reverberation time,
reduce indoor noise. So the polyester fiber sound-absorbing
cotton is cotton insulation.
Polyester fiber sound-absorbing cotton (cotton insulation) the
sound absorption characteristics is not only related with the
thickness and density, but also related to overlay materials and
structure factors. In the construction application also needs to
take into account the cost, beautiful, environmental protection,
moisture, dust, resistance to aging and other aspects of the
problem.
