ABSTRACT:
Cellulosic fibers containing latex solids are recovered from latex bonded broke by agitation of the broke in an aqueous alkaline solution having an alkali metal hydroxide concentration of 0.5 to 1.5 mol percent for a period of time in the range of ten minutes to four hours. The resulting fibers containing cured latex solids may be added to conventional papermaking fibers in amounts as high as 10 to 15 percent by weight for the production of facial quality tissue to produce a high quality product web.
