Preshrinking is a process that is carried out prior to cutting a fabric in order to ensure that garment does not shrink in its dimensions. The textile materials usually undergo significant lengthwise stress during the weaving and finishing process. This results in considerable shrinkage during subsequent use because of the corresponding relaxation forces. Shrinkage occurs in almost all natural fibers and also blends. Before laying out the paper pattern pieces, one needs to preshrink the fabric and straighten the grain. These two simple steps ensure easy-care garments with straight hanging seams and hems.
