A heat resistant and/or fire retardant synthetic fiber is obtained by a process comprising immersing a polyethylene fiber into a solution of acrylic acid or impregnating a polyethylene fiber with a solution of acrylic acid and irradiating the polyethylene fiber with an ionizing radiation to graft polymerize the polyethylene fiber with at least 15%, based on the weight of the polyethylene fiber, of acrylic acid, or a process comprising irradiating a polyethylene fiber with an ionizing radiation and then immersing the polyethylene fiber into a solution of acrylic acid or impregnating the polyethylene fiber with a solution of acrylic acid to graft polymerize the polyethylene fiber with at least 15%, based on the weight of the polyethylene fiber, of acrylic acid.
