WHAT JEANS ARE "SANFORIZED"?
DOES ANYBODY HAVE A LIST OF SANFORIZED JEANS?
Manufacturers of garments made of these fabrics may label their merchandise Sanforized. Thus the retailer and the ultimate consumer can tell at a glance that the fabric in a garment so labeled will not shrink out of fit.
WHAT CAUSES SHRINKAGE?
During spinning, weaving, bleaching, dyeing and the various finishing processes, yarns and cloth are under a continuous tension.
Yarns and/or fabrics are not fixed materials. They consist of separate, stretchable fibers which submit to the tension. In other words, fabrics do stretch in length and width. The tension within the yarns, which is caused by this stretching, can be eliminated when the friction within the fabric is reduced. This reduction in friction occurs during laundering where both water and soap act as a lubricant. The lubricant, along with the mechanical action of the washer, helps the fibers relax and contract to their original length before the elongation takes place. This means that the fabric shrinks and recaptures its original equilibrium.
