Textile Term: Heat Set Finish
Heat set finish is a process used in the textile industry to improve the dimensional stability of certain fabrics. This involves exposing the fabric to high temperatures and pressure to permanently set the fibers in place.
Heat set finishing is typically applied to synthetic fabrics like polyester, spandex, and nylon, to improve their resistance to deformation, shrinkage, and wrinkles. The heat setting process can also improve the fabric's drape, hand, and overall appearance.
The heat set finish may be executed during the manufacturing process, or separately after the fabric has been knitted or woven. The fabric is usually passed through a series of heated rollers, which apply the necessary heat and pressure to set the fibers in place.
Heat set finishes are commonly applied in a range of textile products, such as home furnishings, industrial fabrics, and apparel. The process is particularly important in the production of items that require a precise fit, such as sportswear, swimwear, and lingerie.
