What is Sanforization?
Sanforization is a pre-shrinking process for cotton and cotton-blend fabrics, which reduces the risk of shrinkage after the garment has been washed.
The process was invented by Sanford Lockwood Cluett, and involves the application of moisture, heat, and pressure to the fabric. The fabric is then stretched out and held in place as it is passed through a series of heated rollers. This causes the fibers in the fabric to shrink and settle into their natural position, resulting in a more stable and consistent fabric.
The main advantage of sanforization is that it helps to eliminate the problem of shrinkage in cotton and cotton-blend fabrics. This is particularly important for clothing manufacturers, as it ensures that the finished garments are consistent in size and fit, even after multiple washes. Sanforization also improves the overall quality of the fabric by reducing wrinkles and increasing its durability.
It is widely used in the textile industry, especially for cotton and cotton-blend fabrics such as denim, chino, and poplin. It is a common practice for most clothing manufacturers to pre-shrink fabrics before cutting and sewing garments. This process helps to ensure that the finished garments retain their shape and size, and helps to prevent them from becoming misshapen or distorted after washing.
Sanforization is a critical step in the manufacturing process of many garments, especially those made from natural fibers. It helps to maintain the quality and durability of the fabric and ensures that the finished garments are consistent in size and fit.
