Abstract

1,170,640. Thermoplastic nets. E.I. DU PONT DE NEMOURS & CO. 23 May, 1967 [23 May, 1966], No. 23835/67. Heading B5B. A patterned thermoplastic web 10 is made by passing the molten resin under pressure along a laterally confined path 26, substantially without pressure drop, the path terminating in an outlet passage 28, from the mouth of which it is forced into a patterned casting surface 8 which moves past the said mouth, cooling the web on the surface and removing it. The outlet mouth may have a doctor blade 32 which is provided with a slant surface 44 so as to define a wedge-shaped cavity 42, whereby movement of the roll 8 assists in forcing the resin into the pattern. The blade 32 may also have a ridged surface where it contacts the resin. Suitable apparatus is claimed per se. The web produced may be drawn longitudinally and/or biaxially. The pattern on the web may take the form of relief on a continuous base film; such a base film may be removed, e.g. by a blast of hot air at 700-800‹ C., followed by rapid quenching, to produce an openwork structure of interconnected filaments. A web comprising (a) a plurality of longitudinally extending filamentary shapes joined together at widely spaced longitudinal points relative to the spacing between the filamentary shapes, or (b) a network of strands running parallel and perpendicular to the length of the web, the intersections of the strands being integrally moulded, and wherein, in each case, the remaining portions of the filaments are joined by a thin film, are claimed per se. A long list of suitable thermoplastic resins is specified, with optimum temperatures for extruding and drawing them.
