An object of the present invention is to provide a fiber treatment agent that is capable of forming on fibers a film that has excellent water resistance and excellent adhesion to a matrix resin. The present invention provides a fiber treatment agent comprising an aqueous medium, a water-insoluble polyamide dispersed in the aqueous medium, and a water-soluble polyamide that is present in an amount of 2 to 50 parts by mass per 100 parts by mass of the water-insoluble polyamide.

Fiber treatment agent, carbon fibers treated with fiber treatment agent, and carbon fiber composite material containing said carbon fibers

A chlorosulfonated polyethylene latex, which is safe for living bodies and the environment and can be used as a latex component in a resorcin-formalin-latex adhesive, contains an aqueous dispersion medium, chlorosulfonated polyethylene, and an emulsifying agent of a polyoxyalkylene alkyl ether sulfate of formula (I) below and a fatty acid salt. The latex is excellent in standing stability and mechanical stability. In formula (I), R, R, n, and M represent an alkyl group of 6 to 20 carbon atoms, hydrogen or a methyl group, an integer of 2 to 40, and an alkali metal, respectively.R&#x2014;O&#x2014;(CHCHR&#x2014;O)&#x2014;SOM&#x2003;&#x2003;(I)

An aqueous dispersion of polyamide rubber elastic body, which contains an aqueous medium and a polyamide rubber elastic body emulsified and dispersed in the aqueous medium in the presence of a surfactant. The surfactant is used in an amount of 1 to 20 parts by weight based on 100 parts by weight of the polyamide rubber elastic body, and is for example at least one member selected from the group consisting of a polyoxyalkylene alkyl ether sulfate, a dialkyl sulfosuccinate, a fatty acid salt and an ethylene oxide/propylene oxide copolymer. This aqueous dispersion can produce a molded article having the characteristics of the polyamide rubber elastic body, particularly a molded article which hardly suffers from bleeding of the surfactant and is excellent in transparency.

The present invention provides an aqueous dispersion comprising a polyamide-based rubber-like elastomer emulsified and dispersed therein, wherein 0.8 to 10 parts by weight of a copolymer of ethylene with an ethylenically unsaturated carboxylic acid, relative to 100 parts by weight of the polyamide-based rubber-like elastomer is contained. The aqueous dispersion of the present invention is a novel aqueous dispersion of polyamide-based rubber-like elastomer that is excellent in storage stability at low temperatures, and that can provide processed products excellent in flexibility and heat resistance when used as a coating material.
