WHAT IS "SANFORIZED"?
The Sanforized trademark was first registered in the United States of America in 1930. Today the trademark is registered in over 100 countries worldwide. Our extensive network of global licensees uses the trademark on both 100% cotton and cotton-blend fabrics which meet special test requirements and conform to a precise standard of shrinkage established by The Sanforized Company.
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.
This is uniformly true everywhere in the world, wherever cotton and cotton-blend merchandise is produced and sold, because the same processing, testing and inspection procedures are carried out with each and every licensee.
Sanforized technical service representatives perform constant inspection and check-testing at the plants of textile mills licensed to produce "Sanforized" fabrics. This insures that a uniform standard is maintained.
The Sanforized trademarks are known at both trade and consumer levels worldwide because of their universal assurance of quality. Textile users — manufacturers, retailers, and consumers — have confidence in Sanforized. They ask for it. They have been asking for it for more than 70 years.
The Sanforized license program is unique and without parallel in the textile and apparel industries. Our leadership and expertise in quality shrinkage control are well-known in every major textile market of the world.
