The handkerchief is a kind of sweat-sweeping tool that our fathers often use. At that time, the users of the handkerchief appeared in front of us by the image of a modest gentleman. Nowadays, it is difficult to find the handkerchief in the market. Instead, we have handkerchief paper, and each of us can use handkerchiefs anytime, anywhere.

How can we choose the quality and safety of non-toxic handkerchief paper? Xiaobian has compiled several methods for everyone.
There is a certain basis for the cancer of handkerchief paper. Inferior handkerchief paper merchants add too much talcum powder and fluorescent agent to the manufacture of handkerchief paper in order to increase the aesthetics of handkerchief paper. They are all chemicals that cause great harm to the human body. The main basis for distinguishing between true and false handkerchiefs is to see if excessive amounts of talc and fluorescein are added.

In order to increase the brightness and whiteness of handkerchiefs, unscrupulous merchants often add phosphors in excess. We can use some methods to detect handkerchiefs: cut out a small piece of each paper handkerchief in the same position. And discharge the underside of the money detector to see if each paper handkerchief contains a fluorescent agent. Inferior paper towels emit bright fluorescence when illuminated by an ultraviolet detector.

We all know that the main material of handkerchief paper is wood pulp, and the wood pulp is made of wood. Its main component is carbon. The quality handkerchief paper is grayish after burning. The handkerchief paper made by unscrupulous merchants can't see the difference between the handkerchief and the qualified handkerchief paper. In fact, they use inferior wood pulp. The handkerchief paper made of inferior wood pulp is not enough brightness and softness, so they only Excess phosphor and talcum powder will be added. Our identification method is: in the same environment, put the paper towel in a white porcelain plate to burn, compare the color of each ash, and observe whether there is oil in the porcelain plate. Handkerchief paper with oil marks is an unqualified handkerchief paper.
