Wet spinning of high-strength, low-elongation polyvinyl alcohol fibers
article
The considerations that influence the selection of polymers and spinning conditions for the purpose of preparing a high-strength, low-elongation type of polyvinyl alcohol fiber for use as a reinforcing component in rigid, cold-hardening resins are discussed. A number of polyvinyl alcohol products from commercial sources were spun, and their fibers evaluated. The two products that gave the best over-all results yielded fibers with a tensile strength of 9-10 g/den and a breaking elongation of 4.5-5%. Elongations at break as small as 3.5% were obtained with two low-molecular-weight samples.
To attain optimum values of strength and stiffnes with any polyvinyl alcohol, a careful build-up of the fiber fine structure is necessary. This was brought about in wet spinning by slowing down fiber coagulation, as well as other processing steps.
