At this time, in order to make the fabrics white and bright, a small amount of fluorescent whitening agents are usually added (national standard fluorescent whitening agents are safe). With the increase of using time, the original Fluorescent Brightener on the textile will be lost, and the textile will appear yellow again. At this time, it is necessary to use the detergent containing fluorescent whitening agent for rinsing.
