[Product Description]
Heat yellowing refers to the yellowing of fabric and fading of light-colored fabric that occurs when nylon/spandex fabric is exposed to various heat sources during processing. The main component of anti-yellowing agent SD-3520 is an antioxidant with special structure. It is mainly used to avoid yellowing of nylon fibers when exposed to heat treatment (compression molding) or air heat treatment (heat setting).
