As cyclohexanone is insoluble in water, acetalization of polyvinyl alcohol fiber with emulsion was undertaken
Nonionic emulsifier, such as polyethylene glycole laulylether, give good emulsion and are stable even in acid medium.
Although acetalization takes place smoothly, it is defficult, as in methanol solution, to obtain higher degree of acetalization than 30 mol%.
There the acetalized fibers are non-resistent to boiling water.
