  • Plasma treatment method, plasma treatment apparatus, and plasma-treated long object
    Patent number: 10192722
    Abstract: A plasma treatment method subjects a long object to be treated to plasma treatment by placing the long object to be treated in contact with plasma, the density distribution of which varies while selectively passing the long object to be treated through an area having high plasma density so that a surface of the long object can be thoroughly and uniformly subjected to plasma treatment. The method is applied to a plasma treatment apparatus, and a plasma-treated long object can be obtained by the method.
    Type: Grant
    Filed: April 8, 2013
    Date of Patent: January 29, 2019
    Assignees: SUNLINE CO., LTD.

  • Fishing line and method for production thereof
    Patent number: 8025970
    Abstract: A fishing line is produced by forming a monofilament by subjecting a resin composition (C) containing 90 to 99.3% by weight of a polyamide resin (A) and 0.7 to 10% by weight of a silicone compound (B) having a number average molecular weight of 100,000 to 2,000,000 to melt-spinning and then drawing. This method can provide a fishing line which is excellent in abrasion resistance and also excellent in visibility. In this method, it is preferable to conduct melt-kneading of a part of the polyamide resin (A) with the silicone compound (B) in advance, adding of the residual polyamide resin (A) and further melt-kneading, subsequent melt-spinning, and drawing at a draw ratio of from 4 to 7.
