Sanforized®
Sanforized is a term used in textiles to refer to a specific treatment process applied to fabric or garments to prevent them from shrinking after washing. This process was developed in the early 20th century by Sanford Lockwood Cluett, an American inventor and entrepreneur, and has since become an industry standard.
The sanforizing process involves treating the fabric or garment with a controlled amount of moisture and heat, which causes the fibers to shrink and stabilize. The fabric is then stretched to its original length and width to ensure that it will not shrink any further during washing or use. This process is especially important for cotton and other natural fibers, which are prone to shrinkage due to their high water absorbency.
The sanforizing process has several advantages over other methods of fabric shrinkage control, such as mercerization or resin finishing. Firstly, it is a mechanical process that does not involve the use of chemicals, making it a more eco-friendly option. Secondly, it is effective at controlling shrinkage even after multiple washes, which is important for garments that are frequently laundered. Finally, it does not affect the feel or appearance of the fabric, as can be the case with other shrinkage control methods.
Sanforized fabric and garments are commonly used in a variety of applications, including clothing, bedding, and upholstery. In the garment industry, sanforization is especially important for items such as jeans, which are made from cotton denim that is prone to shrinkage. Sanforized denim is typically used for high-quality jeans that are designed to retain their shape and size over time, even after multiple washes.
When purchasing sanforized fabric or garments, it is important to follow the care instructions provided to ensure that the treatment remains effective. In general, sanforized items should be washed in cold water and dried on a low heat setting to minimize shrinkage. It is also important to avoid ironing sanforized items on high heat, as this can cause shrinkage and damage to the fabric.
In summary, sanforization is a process used in textiles to control fabric shrinkage after washing. It involves treating the fabric or garment with moisture and heat, which causes the fibers to shrink and stabilize, and then stretching the fabric to its original dimensions. Sanforized fabric and garments are commonly used in a variety of applications, including clothing, bedding, and upholstery, and are especially important for cotton and other natural fibers that are prone to shrinkage. Following proper care instructions is essential for maintaining the effectiveness of the sanforization treatment.
