Abstract

7678. Hatschek, L. March 30. Waterproof fabrics.-In making a waterproof felt which may be used for roofing or insulating purposes, finely-powdered Trinidad or other asphalt is mixed with the fibrous material in a mill or mixing-vat, such as is used in paper manufacture. The mixture is then felted in the ordinary way. and passed over heated calendering-rollers. When a small percentage of asphalt is used, asbestos is the fibrous material employed.
