What heat set means?
Heat setting is a process of treating synthetic fibers or fabrics with heat to stabilize their shape and size. Synthetic fibers like polyester, nylon, and acrylic have a memory of their original shape, and heat setting helps to “lock in” the new shape and prevent them from returning to their original shape.
The heat setting process typically involves applying heat to the fabric at a specific temperature for a set amount of time. This can be done through methods such as steaming, ironing, or passing the fabric through a hot air oven. The heat causes the synthetic fibers to relax and take on the new shape, which is then cooled and set in place.
Heat setting is important because it helps to ensure that synthetic fabrics maintain their intended shape and size throughout their lifespan. This process is commonly used in the manufacturing of clothing, upholstery, and other textile products made from synthetic materials.
