ABSTRACT:
An integrated string consisting of plural mono-filaments, each of which being fused together with adjacent mono-filaments at the contact points and externally having sharp grooves produced by twisting along its length and internally defining confined spiral bores between the component mono-filaments along its length. The external spiral grooves produced by twisting provide frictional resistance against slipping without deteriorating the specific surface tenacity and the tensile strength of the component synthetic mono-filaments. The internal spiral bores between the component mono-filaments improve the flexibility of the string.
