Good evening, the detection of fluorescent agent is very simple. It can be irradiated with ultraviolet light according to ordinary banknotes. If there is obvious yellow-green fluorescence compared with purple light source, it means that it contains fluorescent agent (usually stilbene biphenyl fluorescent agent such as CBS and XBS, but this is very harmful to human body, so you can ignore it because it is in washing powder). Carcinogenic aromatic amines. You mean benzidine, right? This can't be used for printing and dyeing clothing fabrics. Unless it is a knockoff, no one will use it to color bedding. At present, there is no simple means to detect benzidine, and small samples need to be sent to the laboratory for analysis. Generally, fabric dyeing is acid dye or reactive dye, and sulfonate is essentially non-toxic. I hope you don't worry. Warm noodles indicate that the quality of this quilt is quite good:-)
