Abstract
The invention is a hollow fiber and tubesheet assembly which comprises (A) a non-random fiber bundle comprising water wet cellulose ester hollow fibers wherein the fiber is water wet when the assembly is fabricated, wherein any of said fibers processed using plasticizers have been leached to remove the plasticizer; and (B) a tubesheet which comprises the reaction product of: (i) an epoxy resin comprising about (a) between about 10 and 100 percent by weight of a diglycidyl ether of a dihydroxy benzene; (b) between about 0 and about 90 percent by weight of a polyglycidyl ether of a polyhydric phenol which is not a diglycidyl ether of dihydroxy benzene; (ii) a curing agent in sufficient amount to cure the epoxy resin composition; wherein a portion of the hollow fibers are embedded in the tubesheet.
