20130130029 | SUPER-HIGH-MOLECULAR-WEIGHT POLYOLEFIN YARN, METHOD FOR PRODUCING SAME, AND DRAWING DEVICE - An ultrahigh molecular weight polyolefin yarn of the present invention has been drawn and has a melting point that is determined as a maximum peak temperature measured by a differential scanning calorimeter (DSC) at a temperature rise rate of 20° C./min, and the melting point is higher than a melting point of the yarn before drawing. In a production method of the present invention, a drawing bath ( | 05-23-2013 |
20130125739 | PROTECTIVE SLEEVE FOR MOTOR COMPONENT AND METHOD FOR MANUFACTURING SAME - The protective sleeve for a motor component of the present invention is obtained by braiding multifilament yarns made of synthetic fibers into a cylindrical braided cord of at least 24 strands. The multifilament yarns have a single-yarn fineness of at least 15 dtex but less than 30 dtex and the yarn total fineness of a single braid unit of the braided cord is in the range of 800 to 1500 dtex. This protective sleeve has good covering properties and few voids. Therefore, a protective sleeve for a motor component is provided that has high partial discharge characteristics (electrical insulation performance) and good electrical insulation properties even when a step of washing away the raw yarn oil solution applied to the filaments was omitted. | 05-23-2013 |
