Abstract
In order to improve the dyeing properties of a wet spun fiber, the latices of various polymers containing quaternary vinyl pyridinium salts described in the previous paper (part III) were used for blending with polyvinyl alcohol. The dye absorption and color-depth and washing fastness of dyeings of a fiber containing the copolymer particles were increased with increasing degree of quaternization in the copolymer. By spinning the polyvinyl alcohol solution containing the quaternary vinyl pyridinium salt-methyl acrylate copolymer latex, followed by hot drawing, hot shrinking and benzalization, the fiber having fairly good dyeing properties was obtained. And also, as results of dlending of the copolymer, acid resistance and heat setting properties of the benzalized fiber were somewhat improved. By using chlorobenzaldehyde to impart a better acid resistance, the fiber sufficiently stable under the dyeing condition of wool with acid dye was obtained. The fiber may be suitable for blending with wool.
