Abstract: A water-soluble polyvinyl alcohol resin filament is provided, which is formed by melt-spinning a material consisting essentially of a water-soluble polyvinyl alcohol resin having a 1,2-diol structural unit represented by the following general formula (1). A nonwoven fabric is also provided, which is produced by using the water-soluble polyvinyl alcohol resin filament. Therefore, the nonwoven fabric is excellent in water solubility at a lower temperature, and substantially free from bubbling during dissolution thereof in water. In addition, a fully saponified PVA can be used for melt-forming. This suppresses emanation of acetic acid odor, thereby improving the working environment. wherein R1, R2, R3, R4, R5 and R6, which may be the same or different, are each a hydrogen atom or a monovalent organic group, and X is a single bond or a connecting chain.
