In the complex landscape of textile manufacturing, the quality and efficiency of fiber processing are heavily reliant on the effective use of chemical auxiliary agents. Among these, Fluorescent Brightener 140 (Optical Brightening Agent SWN) stands out as a fundamental component, playing a crucial role in achieving desired aesthetic and performance outcomes.


This versatile brightening agent, a specialized coumarin derivative, is particularly valued for its ability to enhance the whiteness and brightness of a broad spectrum of fibers, including natural materials like wool and cotton, as well as synthetics such as polyamide and acrylic fiber. Its mechanism involves absorbing ultraviolet light and re-emitting it as visible blue light, effectively masking yellowing and imparting a vibrant, clean appearance to the processed fibers. For manufacturers, understanding how to best buy fiber processing auxiliary agent for optimal results is key.
