heat-setting

Heat-setting is a process that uses heat to permanently fix materials like plastics or fabric pleats into a desired shape. In textiles, it's a finishing process that sets the weave of fabrics to their final dimensions, removing wrinkles and straightening the weave. This is sometimes called heat-setting when applied to synthetic fibers, and it's also used to permanently set pleats and surface effects. Heat transfer printing is another textile application where a pattern printed on paper is transferred to fabric using heat. In food preservation, thermal processing involves using specific temperatures and times to eliminate microorganisms, a method pioneered by Nicolas Appert for canning foods.1234
