Dimensional stability (in fabric) pertains to a fabric's ability to maintain its initial size and shape even after undergoing wear and care, which is a desirable property. Textile manufacturing is based on the conversion of fiber into yarn, yarn into fabric, includes spinning, weaving, or knitting, etc. The fabric passes through many inevitable changes and mechanical forces during this journey. When the products are immersed in water, the water acts as a relaxing medium, and all stresses and strains are relaxed and the fabric tries to come back to its original state.
The more dimensionally stable a fabric is, the less it is subject to shrinkage. Shrinkage is the change of dimensions in textile products when they are washed or relaxed. The change is always expressed relative to the dimensions before the exposure of washing or relaxing. Shrinkage is also called residual shrinkage and measured in percentage. The major cause of shrinkage is the release of stresses and strains introduced in manufacturing processes.
