Abstract
In spinning the saponifized substance of the copolymer of vinylacetate and allilidenediacetate, and in emulsion mixture spinning of the above copolymer choicely saponifized the acetic group of allilidenediacetate, the character of the solution for spinning, and the properties of the fibre were studied, respectively.
The results were following:
(1) The boiling-water resistance and properties of the fibre from the saponifized substance of the copolymer are generally inferior, and they are reduced in proportion to the quantity of the aldehyde group of the copolymer.
(2) The boiling-water resistance, stress-elongation relationships, and elastic recovery of the heat treated fibre by emulsion mixture spinning of the partially saponifized substance of the copolymer and P. V. A. are superior to those of the usual formalized fibre.
