The purpose of the fluorescent agent on the textile is to whiten the color, which is difficult to wash off, just like the dyeing on the textile. Fluorescent agent (also known as brightener, optical brightener, fluorescent brightener) detection, here is a simple and low-cost method, you can use 365nm ultraviolet small flashlight irradiation (can also be ultraviolet money detector), if there is blue-purple fluorescence (generally blue, purple, but also green, red, and the original color contrast changes, obviously a lot more bright and bright, just look at a few more other items to compare), it contains fluorescent. This kind of flashlight is sold on TB, search (fluorescent agent detection), not expensive generally more than 10-30 yuan, or more practical, textiles, plastic products, skin care products, paper, etc. (some foods have special fluorescent reactions, such as rice fat will fluoresce reactions) containing fluorescent agents can be irradiated.
In the future, pay attention to testing, especially for babies, or personal products and skin care products. If it is a three-no product, there is indeed a risk of containing fluorescent agents. In everyday life, there are many opportunities to come into contact with fluorescent agents.
As long as it does not exceed a certain standard (the above method can only detect whether it contains fluorescent agent, not whether it exceeds the standard), it will bring a lot of benefits to our lives. If you come into contact with it in excess, it can cause harm to the human body. Hint:
Ultraviolet light cannot be seen without irradiating the fluorescent substance (if there is a small amount of white light, it is part of the visible light emitted by the lamp beads, not ultraviolet light), and if the reflection can be seen, it means that the irradiated object has a fluorescent reaction. Ultraviolet rays are harmful to the human body, avoid direct exposure to the human body and use for a long time. If you don't understand, you can continue to ask, hope, thank you.
