Some factors affecting the dimensional stability of vinylon fabrics under various washing conditions is discussed. It is shown that the water holding capacity of the fabrics has significant effect on their dimensional stability. It appears that the mechanism of shrinkage of vinylon fabrics is similar to that of cotton fabrics. The effect of temperature and agitation during washing on the shrinkage of the fabrics, and also progressive shrinkage during washing are interpreted qualitatively in terms of the influence of the change of the water holding capacity. As with rayon fabrics, the tighter the construction of the fabrics is, the less their dimensional stability. The stress to extend the fibers 5% in 90°C water has a fairly important influence on the dimensional stability, but the water holding capacity is more important. The fiber shrinkage index in hot water has little effect on the dimensional stability of vinylon fabrics.
