    摘要: A fine powder of an alkaline earth metal carbonate selected from the group consisting of barium carbonate, strontium carbonate and calcium carbonate, in which a primary particle of the powder has a mean diameter of 30 to 90 nm, in which the mean diameter is measured on a circle obtained from a projected area of the primary particle, and in which an accumulated volume of micropores having a pore size in the range of 10 to 20 nm is not less than 5×10−2 cm3/g can be easily dispersed in an aqueous medium in the form of essentially primary particles by an industrially employable dispersing method.

    摘要: The silicone-based fiber finishing agent is particularly suitable for synthetic fiber-made fabric materials such as waddings of polyester fibers to impart excellent softness and smoothness in touch and free from yellowing even by heating with high resistance against dry cleaning. The fiber finishing agent comprises (A) an organopolysiloxane of a substantially linear molecular structure terminated at each molecular chain end with a silanolic hydroxy group or alkoxy group and having at least one amino-substituted hydrocarbon group bonded to the silicon atom in a molecule, (B) an epoxy-containing alkoxy silane compound such as methyl dimethoxy 3-glycidyloxypropyl silane and (C) an epoxy-containing organic compound free from silicon such as glycidyl alcohol and glycidyl methacrylate.
