126.96.36.199 Relaxation Shrinkage
This type of shrinkage occurs when the latent strains in the fabric, acquired in manufacture, are released by the fibers. This tends to occur more readily in laundering than in drycleaning. Heat, steam or water, and mechanical action are the primary causes. Such shrinkage can be minimized by manufacturing controls or special finishes. It is beyond the control of the consumer, drycleaner, or launderer. Puckering or bubbling can result when relaxation shrinkage occurs unevenly in a fabric. This condition may not respond to restorative measures.
