Abstract

1395810 Stretching filaments ALLIED CHEMICAL CORP 14 Sept 1972 [23 Sept 1971 6 Dec 1971] 42763/72 Heading B5B Drawn filaments made of a synthetic linear polymer are produced by a continuous process in which filaments are melt spun at 235‹ to 350‹ C., quenched, pretensioned at a tension of between 0À005 and 0À15 g.p.d. and then stretched at a temperature between the second order transition temperature and 5‹ below the melting point. The filaments are heated to the drawing temperature instantaneously and the heating and drawing are simultaneous. This is accomplished in the examples by heating with a jet of steam to raise the temperature and localize the draw point. The process is exemplified for polyethylene terephthalate and polycaproamide.
