  • Patent number: 10047219
    Abstract: Provided is a polyolefin-based resin composition capable of obtaining a molded product having a high modulus of elongation and a low coefficient of linear expansion. The polyolefin-based resin composition includes a polyolefin-based resin containing either one or both of an acid-modified polyolefin-based resin and a polyolefin-based resin with a hydroxyl group, and flaked graphite. The flaked graphite is uniformly dispersed in the polyolefin-based resin. As a result, a molded product formed by using the polyolefin-based resin composition has excellent mechanical strength such as a high modulus of elongation, a low coefficient of linear expansion, and high dimensional stability, and can be used for various applications such as a material that is suitable for use as the exterior panels of automobiles or a steel sheet replacement material.

  • Patent number: 9963804
    Abstract: A polyamide monofilament is characterized in that the abrasion tension thereof when passed through a ceramic guide is 0.3 cN/dtex or less and in that the amount of static electricity generated at the exit of a chromium round bar guide, which is a frictional body, when the polyamide monofilament is passed through the chromium round bar guide, is 300 V or less. This polyamide monofilament and fiber package provide a gauze woven fabric for which tension is low when passing through a thread path guide when warping warp yarn, for which generation of static electricity is suppressed, and which has excellent weaving productivity.

  • Patent number: 9889598
    Abstract: A system for forming a waterproof seam between to sewn materials. The seam is formed using an adhesive coated thread. A thin strip of adhesive is placed between the two materials at the seam line. As the coated thread is sewn into the seam heat and pressure are simultaneously applied, melting the adhesive coating thereby filling the needle punctures. The melted adhesive coating will also flow into the areas between the needle punctures and between the materials. The heat and pressure applied to the coated thread will also melt the adhesive strip, causing additional adhesive to flow into the needle punctures and the areas between needle punctures.

  • Patent number: 9828728
    Abstract: The present invention relates to an improved process for producing chemical cellulose pulp wherein biopolymers are added immediately before, during or after a bleaching step, depending on pulp characteristics and on process conditions used. The biopolymers according to the present invention are starches chemically modified by an etherification reaction. This treatment results in a differentiated pulp having improved physical, chemical and mechanical properties when compared with cellulose pulps obtained by traditional processes. The use of said biopolymer alters the relations between important pulp properties rendering their application in papermaking process advantageous. This differentiation increases the possibilities of use and also of new applications, including for the substitution of pulps produced from other cellulose sources.
