WATER CONTAINING AROMATIC POLYAMIDE PULP AND PROCESS FOR PRODUCING THE SAME

摘要

A water-containing aromatic polyamide pulp which is good in dispersibility in water and good in openability, is excellent in adhesiveness to rubber and gives a high mechanical strength when used in a beater sheet, which pulp can be obtained by dispersing the aromatic polyamide pulp in an epoxy resin emulsion in which the glycidyl groups of the epoxy resin have been partially hydrolyzed to allow the epoxy resin to adsorb on the aromatic polyamide pulp, and then dispersing RFL in the system to instabilize the latex rubber, thereby allowing the RFL to adhere to the surface of the aromatic polyamide pulp, and thereafter dehydrating the pulp to obtain an aromatic polyamide pulp having a water content of 30 to 95 % by weight.
