    Abstract: A method for continuous weight reduction and mercerization of a cloth material. The cloth material which is impregnated with a caustic liquid is first treated with humid heat in a no tension condition to effect reduction in weight and then the cloth material is brought into frictional contact with friction rolls under the same humid heat to mercerize the cloth material in a continuous manner. The method is carried out within a high pressure steamer drum body in which the high humid heat is maintained. A group of rolls are arranged within the fore half portion of the high pressure steamer drum body to convey the cloth material in the no tension condition. In the hind half of the drum body, there are arranged a group of guide rolls to further convey the cloth material with a predetermined degree of tension applied thereto. Some of the group of guide rolls are driven at a variable speed to bring the cloth material into frictional content with them.

    Abstract: Polyester polymer is recovered from polyester fibers (in the form of filaments, yarns or fabrics and the like, both dyed and undyed), and used in the production of new undyed fibers, films, and other polymer products through the process of: stripping the dye from the dyed polyester fibers by contacting the fibers with a dye-stripping solvent for polyester polymer at a temperature below which the polyester fibers dissolve and above which the crystalline lattice of the polyester fibers swell so as to release the dye; then removing essentially all of the dye-containing dye-stripping solvent which is not absorbed by the fibers and fabrics; then contacting the wet solvent-laden fibers, possibly containing residual dye, with sufficient addition of a dissolution solvent under dissolution conditions for polyester fibers; thereafter precipitating the polyester out of; and, separating the polyester from the solution.
