WATER-RESISTANT OPTICAL FIBER YARN, AND APPARATUS AND METHOD FOR MANUFACTURING THE SAME

摘要

Disclosed are a water-resistant optical fiber yarn and an apparatus and a method for manu¬ facturing the same. The method includes steps of supplying an optical fiber yarn 100 having a predetermined diameter, forming a scratch surface 120 on a surface of the optical fiber yarn 100 through a sanding treatment or an etching process, coating the surface of the optical fiber yarn 100 having the scratch surface with a synthetic resin 200, curing a coated optical fiber yarn 100' by naturally drying the coated optical fiber yarn 100 ' or drying the coated optical fiber yarn 100' using a drier, and storing the coated optical fiber yarn 100' by winding the coated optical fiber yarn 100'. The apparatus includes a supplying unit 2, a surface treatment unit 4, a coating treatment unit 6, a drying unit 8, and a winding unit 10.
