ABSTRACT:
Poly(2-methyl-1,5-pentylene) terephthalamide is discussed herein. It is manufactured in a process starting with a nylon salt made from terephthalic acid and 2-methyl-1,5-pentylene diamine and an excess amount of the diamine. The polymer is spun to form monofilaments. The monofilaments may be used, among other things, to form dryer screens for use in a paper forming process.
