In the process of manufacturing household paper with native wood pulp, in order to achieve its good softness, the manufacturer will add a certain amount of native short wood pulp fibers to the pulp. However, the combination of short fibers with other long fibers is not very strong, so a very small amount of short fibers will escape during use, commonly known as "paper drop powder".
Dropping paper powder under reasonable use will not cause harm; In the process of manufacturing household paper using native grass pulp or recycled pulp, some manufacturers add a certain amount of talc powder to the pulp in order to improve softness and reduce production costs. So, when users use it, talc powder is very easy to fall out, which is commonly known as "powder shedding".
