METHOD AND APPARATUS FOR PRODUCING SYNTHETIC RESIN FILM YARN USING MONO YARN, AND THE SYNTHETIC RESIN FILM YARN

摘要

The present invention relates to production of synthetic resin film yarn, in which during or after the production of synthetic resin mono yarn, synthetic resin mono yarn (2) of 0.15-0.3 mm diameter (W1) is press-processed by a press roller (10) to produce a synthetic resin film yarn (4) having a lateral width (W2) which is 2-7 times the diameter (W1) of the finished mono yarn (2) and tensile strength which is 1-1.8 times of a synthetic resin film yarn of equal denier rating due to the forging effect. As such, the present invention exhibits markedly higher tensile strength in comparison to the conventional synthetic resin film yarn of equal denier rating and also allows the unit production cost of the film yarn to be lowered.
