ROPE AND METHOD OF MANUFACTURING THE SAME

NATIONAL INSTITUTE OF ADV...

1. A rope including a yarn twisted by using a raw thread of a polyethylene fiber having an ultrahigh molecular weight and a strand twisted by the yarn and subjected to rope-making through the strand,wherein an oil content is removed from the yarn and an affinity enhancing treatment is performed over a surface of the yarn,
a resin coating layer for protecting the rope is formed on an external surface of the yarn, an external surface of the strand or an external surface of the rope,
the resin coating layer is configured to bind the raw thread in an inner part of the yarn, and
the affinity enhancing treatment includes a UV treatment method or an atmospheric plasma method to cause an oxidation reaction over an exposed surface of the polyethylene fiber of the yarn and thereby to cause introduction of an oxygen containing functional group, O, OH, or a combination thereof, to CH that is included in a chemical formula of the polyethylene fiber of the yarn.
