    摘要: Monofilaments are made from films of unoriented, polymeric resin thermoplastics. The method comprises providing strips or tapes of the unoriented films, twisting the tapes into a generally cylindrical cross-section and drawing the twisted tape to obtain an oriented, round-in-cross-section, monofilament. In the preferred embodiment, molding is carried out by drawing down the twisted tape.
