Method of forming twisted multiple strand synthetic twine, twines produced thereby, and fishnets formed thereof

Abstract

A composite multiple strand or filament twisted fishnet twine (11, 11') formed of synthetic material, methods for forming the same, and fishnets (10) formed therefrom, characterized in the use of a plurality of relatively fine, small diameter synthetic filaments (15.sub.a -15.sub.n) which may be on the order of 210 denier and which are twisted together in one of an "S" or a "Z" configuration to form a first multiple filament "B" strand (15) which is thereafter twisted with a plurality of relatively thick monofilament "A" strands (14.sub.a -14.sub.n) formed of synthetic material with either a "Z" or an "S" twist to form a coreless twine (11, 11') in which all of the "A" and "B" strands (14.sub.a -14.sub.n and 15) are of equal length per unit length of the twine (11, 11') and the individual fibers (14.sub.a -14.sub.n) and (15.sub.a -15.sub.n) are all exposed on the outer surface of the twine along substantially the entire lengths of the individual fibers. In one exemplary form of the invention, twenty-six filaments (15.sub.a -15.sub.n) of approximately 210 denier are twisted in a clockwise direction to form an "S" twisted "B" strand (15) which is thereafter twisted with four monofilament "A" strands (14.sub.a -14.sub.n) in a "Z" or counterclockwise direction to form a composite twine (11); while in another exemplary form of the invention, the relatively fine multiple filaments (15.sub.a -15.sub.n) are twisted with a "Z" twist to form a multiple filament "B" strand (15) which is therafter twisted with the monofilaments (14.sub.a -14.sub.n) in an "S" configuration to form a composite twine (11'). Modified forms of twines (11, 11') are described employing a multiple filament twisted "B" strand (15) employing from sixteen to twenty-six or more fine filaments with the multiple filament "B" strand (15) thereafter being twisted together with a plurality of monofilament "A" strands (14.sub.a -14.sub.n) ranging in number from about four to about fourteen strands.
