Abstract
A method for the manufacture of fiber ropes, according to which a braid with or without a core is produced, and this assembly, made of high performance, degreased fibers is impregnated by passing it through an impregnation bath, containing polyester urethanes and some aromatic isocyanate, which constitutes the reticulant, and then drying.
Claims7
A method of making braided ropes of aromatic polyamide fibers in a manner to provide high strength, little elongation and high flexibility and which are resistant to deterioration comprising the steps of:
- providing a plurality of strands of aromatic polyamide fibers, braiding said fibers together to form a rope, impregnating said braid with an aqueous dispersion of a flurocarbon resin, heating said rope to remove moisture therefrom, applying a predetermined tension on said rope, and removing said rope.
