New information concerning spontaneous elongation of acetate fibers

Structure, Properties


The ability of acetate fibers to experience spontaneous changes in their linear dimensions under the action of vapors of aprotic, amphiprotic, and protic solvents, which are widely used in scientific studies and engineering practice, has been investigated. In the vapor phase of solvents that are able to produce the lyotropic LC phase in cellulose derivatives, the phenomenon of spontaneous elongation of fibers has been discovered. This phenomenon has been observed for both cellulose diacetate and triacetate yarns, and their elongation can achieve ∼ 120–180%. In some systems, one can observe the reverse process that represents a spontaneous contraction of the sample after its self-elongation in solvent vapor. To study the above phenomena, a well-known system based on cellulose acetate and nitromethane is considered to be a reference system. The phenomenon of spontaneous elongation is proposed for use as a test for estimating the ability of the (cellulose ether)-solvent system to experience LC ordering.
