Scanning electron micrograph (SEM), coloured gold, of the hooked surface of a hooks and loops fastener. A common fastener, it is made of nylon material manufactured in two separate pieces, one with a surface consisting of loops, the other with a surface of hooks (shown here) which catch in the loops & fasten the two pieces together. The loops are loosely woven strands in an otherwise tight weave; the hooked surface is made by cutting the loops. Magnification: X 16 at 35mm size.
