In the process of making household paper with virgin wood pulp, in order to achieve its softness, manufacturers will add a certain amount of virgin short wood pulp fibers to the pulp, and the combination of short fibers and other long fibers is not very strong , So a very small amount of short fibers will escape during use, which is what we commonly call "paper powder drop".
If the paper powder is used properly, it will not cause harm. In the process of using virgin straw pulp or recycled pulp to make household paper, some manufacturers, in order to achieve the purpose of improving softness and reducing production costs, A certain amount of talc is added to it. Therefore, the talc powder is easy to fall out during the user's use, which is what we commonly call "dark powder".
