A multi-strand nylon rope having improved abrasion resistance is comprised of a plurality of strands. Each strand is comprised of a plurality of yarns wherein each yarn is formed of a predetermined number of filaments. The filaments of each yarn are twisted together to form a yarn of a predetermined size, the twist direction being opposite that of the final ply yarn direction. For a right lay rope a sufficient number of filaments are twisted together in the left or 'S' direction to produce a yarn of a predetermined size. Three or more yarns prepared in this manner are then plied or twisted together in the opposite or right direction. The cover for each strand is formed of alternate yarns of standard (i.e. round) and oblong filaments, respectively, the oblong filaments having a modification ratio of three, forming a rope having increased abrasion resistance, a hand and feel that is not stiff or unmanageable and which resists strand-to-strand wet abrasion.

Method for producing a rope having superior friction and wearing

A unique rope for use in commercial fishing comprising floating and sinking portions. The sinking portion has blended yarns made up of a blend of first and second non-metallic synthetic filaments in proportions to yield a sinking rope portion having a specific gravity greater than one. The sinking rope portion comprises strands having yarns of substantially the same diameter. The floating portion of the rope is formed by replacing selected ones of the blended yarns in each strand with yarns formed of a material having a specific gravity of less than one. The replacement yarns and the blended yarns are of the same diameter to enhance the integrity and strength of the rope. The yarns omitted from the sinking section and replaced with the yarns having a specific gravity less than one are terminated at staggered intervals along the rope and their replacement yarns are inserted at like staggered intervals forming a merged region between the sinking and floating portions having a tensile strength which is equivalent to the tensile strength of the sinking and floating portions. The rope material sensitive to ultraviolet radiation is surrounded and thus protected by the material resistant to ultraviolet radiation. The ultraviolet sensitive material may also be treated with a stabilizer material which enhances resistance to ultraviolet radiation. A method is also disclosed for producing the floating/sinking rope.
