Abstract of the Disclosure The invention provides rapidly shrinking fibers having low solubility in water and capable of shrinking in water at 20°C by not less than 30% in not longer than 10 seconds. These fibers are obtained, for example, by spinning, draw- ing and heat-treating a carboxy-modified polyvinyl alcohol under specific conditions. Yarns made from a fiber of this kind in conjunction with a fiber for slowing the shrinkage in water as well as nonwoven fabrics made by incorporating yarns containing said rapidly shrinking fibers in nonwoven fabric shrinkable upon absorption of water are suited as means of tightly fitting edge por- tions of disposable diapers to the thigh.
