| Abstract: | Conclusions A brightening and sizing preparation has been developed which is based on a copolymer having a high content of acrylic ester units, prepared by a one-stage, high-temperature hydrolysis of an acrylonitrile copolymer in the presence of a mixture of water and an aliphatic alcohol.Use of this preparation (as compared with the use of polyvinyl alcohol) ensures a 15–25% reduction in breakage and amount of waste in rewinding viscose textile yarn.Translated from Khimicheskie Volokna, No. 2, pp. 27–28, March–April, 1988. |
