    Abstract: 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.

    Abstract translation: 具有改善的耐磨性的多股尼龙绳由多股构成。 每条纱线由多条纱线组成,其中每条纱线由预定数量的细丝形成。 将各纱线的长丝捻合在一起形成规定尺寸的纱线,扭转方向与最后的纱线方向相反。 对于正确的绳索,足够数量的长丝在左或“S”方向上被扭绞在一起以产生预定尺寸的纱线。 然后以这种方式制备的三根或更多根纱线沿相反方向或右方向绞合在一起。 每条线的盖子分别由标准(即圆形)和长方形长丝的交替纱线形成,长方形长丝的改性比为三倍,形成具有增加的耐磨性的绳索,手感和手感不牢固或难以控制 并且其抵抗线对股的湿磨损。

    Abstract: Rope having improved working qualities and hand without need to contain sizing or lubricants consists of a plurality of strands of fibrillated polyolefin film having a delustered surface. The film is delustered by surface abrasion prior to fibrillation and twisting into strands. Such rope exhibits low internal friction producing its good working qualities and low abrasion to objects in which it comes in contact producing its improved hand.
