Vinylidene fluoride resin monofilament and process for producing the same |
摘要 |
A vinylidene fluoride resin monofilament excellent in tensile strength and knot strength is further improved in abrasion resistance by heat-treating the oriented monofilament for such a short time period as to relax the orientation of only the surface portion of the monofilament. The vinylidene fluoride resin monofilament improved in abrasion resistance is characterized by a lower birefringence at the surface relative to a high average birefringence in a section perpendicular to the axis thereof.
