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)
