Abstract: A separable fastening device, resistant to flame and having a very large number of closely spaced hooking elements of the hook and loop type, such that pressing opposed surfaces of two fastening members together in face-to-face relation will engage a large number of hooks and loops, is disclosed; the loops are formed from a flame and elevated temperature resistant nylon fiber of very low denier, many filaments of which must first be twisted in an S direction and two each of the twisted strands then reverse plied together in the Z direction to produce a stabilized yarn having sufficient strength and body to form the loops.
