ABSTRACT:
There is disclosed an improved process for phosphating asbestos fibers by reacting phosphorus chlorides with asbestos fibers in a first reaction vessel heated to a temperature within the range of the boiling temperature of the selected phosphorus chloride at atmospheric pressure and 200.degree. C. above the boiling temperature of said phosphorus chloride, then the phosphated asbestos fibers are cured in a second chamber and purged of any volatile by-product formed during the phosphating step. The products obtained possess reduced haemolytic activity.
