Abstract
Reaction products of diethylaminoethyl (DEAE)-cotton and aminoethyl-cotton (aminized) with 1,2-epoxy-3-chloropropane (epichlorohydrin), 1,2-epoxy-3,3-dichloropropane, 1,2-epoxy-3,3,3-trichloropropane, and 1,2-epoxy-4,4,4-trichlorobutane, 1,2-epoxypropane, 1,2-epoxyhexafluoropropane, and 1,2-epoxy-3-bromopropane were studied microscopically. The methacrylate layer-expansion technique was used to evaluate the extent of chemical reaction. Epichlorohydrin appeared to be the most efficient cross-linking agent. The chlorinated epoxides capable of dehydrohalogenation after epoxide ring openings appeared to be good cross-linking agents. Electron mcirographs demonstrate the effects of the above treatments on fiber morphology.
