摘要： An inorganic fiber sizing agent that contains at least one carbon nanostructure selected from the group consisting of carbon nanotubes and carbon nanofibers, a resin, and a surfactant. If the total content of a nonvolatile content of the resin and the surfactant is taken as 100 parts by mass, the inorganic fiber sizing agent contains the surfactant at a ratio of 2 to 50 parts by mass.

摘要： An object of the present invention is to provide a sewing thread treatment agent, and a sewing thread, each achieving low friction properties across a wide range of sewing speeds. As a solution, a sewing thread treatment agent is provided, which is characterized in that it contains a hydroxy-terminated polydimethylsiloxane (A), a nonionic surfactant (B), and at least one type of wax (C) selected from paraffin wax, oxidized paraffin wax, polyethylene wax, oxidized polyethylene wax, and carnauba wax.

摘要： The present invention addresses the problem of suitably suppressing fluffing during a spinning process. This method for producing a treatment agent for synthetic fibers, wherein the boron content in the nonvolatile content of the treatment agent for synthetic fibers as detected by ICP emission spectrometry is 200 ppm or less, comprises: an addition step wherein a (poly)oxyalkylene derivative is produced by adding an alkylene oxide to an alcohol in the presence of a catalyst that has a boron atom in each molecule; and a removal step wherein the catalyst is removed so that the boron content in the nonvolatile content of the treatment agent for synthetic fibers as detected by ICP emission spectrometry becomes 200 ppm or less.

摘要： The present invention addresses the problem of suitably improving the converging ability of synthetic fibers. This synthetic fiber treatment agent contains a polyoxy alkylene alkyl ether obtained by proportionally adding, to 1 mole of a monovalent aliphatic alcohol having a hydroxy group at the beta-position of an alkyl chain having 4 or more carbon atoms, a total of 1-30 moles of an alkylene oxide having 2-4 carbon atoms.
