Latest Patents

Oshima's latest patents include a synthetic fiber treatment agent and synthetic fibers that incorporate this treatment agent. The synthetic fiber treatment agent contains a silicone and a polyoxyalkylene alkyl ether, which is formulated with an alkylene oxide of 2 to 4 carbon atoms. This is added at a ratio of 1 to 30 moles in total to 1 mole of a monohydric aliphatic alcohol with a hydroxy group at the β-position of an alkyl chain containing 4 or more carbon atoms. Another notable patent is for a treatment agent for carbon fiber precursors, which includes a specific (poly)oxyalkylene derivative and a smoothing agent. The smoothing agent is composed of at least one selected from amino-modified silicone, polyether-modified silicone, dimethyl silicone, and an ester compound. The carbon fiber precursor treatment agent is designed to contain the (poly)oxyalkylene derivative at a mass ratio of 5% to 80% and the smoothing agent at a mass ratio of 20% to 95
