摘要: The invention comprises treating asbestos cloth and other asbestos products to reduce the dust emitted by them during handling and use. This is done by distributing a small amount of polymeric particles throughout the product to bond the fibers to one another, while leaving the properties except the dustiness essentially unchanged. The preferred method consists in impregnating asbestos cloth with an aqueous emulsion or suspension of the polymeric material and removing the water.
