Method for controlling and removing dust and other particles from a material

Research output: Patent

Abstract

An apparatus for delivering electrostatically charged particles to a carpet or fabric material is provided for controlling and removing dust from the material. The apparatus comprises a container for storing particles which are to be electrostatically charged and a tube or pipe for delivering the particles from the container to the carpet or fabric material. A source of compressed air or vacuum is provided for expelling particles at high velocity from the container to the carpet or fabric material. The tube or pipe is made of a material such that a minimum charge to mass ratio of ~1 × 10 -4C/kg is imparted to the particles by frictional contact on the inside of the tube or pipe when the particles are passed down the delivery tube or pipe at high velocity.
