Document Type and Number:
WIPO Patent Application WO/2017/221318
Kind Code:
A1
Abstract:
Provided are a rope having excellent abrasion resistance and bending resistance, and a manufacturing method for realizing such a rope. The rope (1) includes yarns obtained by twisting starting yarns (5) comprising ultra-high molecular weight polyethylene fibers (6) and strands (2) obtained by twisting the yarns, and is manufactured from the strands (2). A resin coating layer for protecting the rope (1) is formed on the outer surface of the yarns, the outer surface of the strands (2), or the outer surface of the rope (1). The manufacturing method for the rope (1) comprises performing a pretreatment step I for removing oil included in the rope (1) and treating the surface thereof so as to have affinity to a given resin, followed by a resin coating step II for forming the resin coating layer for protecting the rope (1) on the outer surface of the yarns, the outer surface of the strands (2), or the outer surface of the rope (1). Since the resin coating layer for protecting the rope (1) is provided, foreign substances such as sand in seawater do not enter into the interior of the rope (1). As a result, the longevity of the rope (1) is improved.
