Abstract
The present invention provides a method of removing contaminants from industrial process fabrics relying upon cryogenic techniques, wherein the fabric is impacted with solid particles of carbon dioxide. A cryoblaster projects the carbon dioxide particles at the fabric. The cryoblaster scans over the entirety of the fabric at a scanning rate particle velocity, and particle flow rate in order to insure that the fabric is cleaned without suffering any damage.
Claims10
A process for removing contaminants from industrial process fabrics used in wet laid and dry laid processes comprised of the steps of impacting a surface of an industrial process fabric having contaminants on the surface with solid particles of carbon dioxide and removing the contaminants from the industrial process fabric.
A process for cleaning the surfaces and interstices of industrial process fabrics, the process comprising:
- impacting the inorganic and organic materials deposited on the surface of the fibrous components of industrial process fabrics during use in wet laid or dry laid processes, selected from a group consisting of cellulosic fibers, synthetic staple fibers, latex adhesives, olefinic polymer deposits, resin, pitch, tar, fillers, extenders, and starch residues with carbon dioxide particles to effect dislodgment and removal of the surface contaminants.
