There are many types of felts on the market, and the felt manufacturers will introduce us how to distinguish the quality of felts.
On the one hand, if the unit volume weight of the felt is too large, it will lose its elasticity; while the unit volume weight is too small and it will lose its abrasion resistance. In addition, the thickness, the thickness of the hair, etc. all have an impact on various properties, and the user can be appropriately selected according to the requirements of use. In addition, each type of felt is divided into special felt and general felt. The difference between the varieties is divided according to the thickness of the raw material, the size of the unit volume weight and the difference in color.
This is the introduction to the knowledge of felt quality discrimination, I hope it can be helpful to everyone, so that you can also buy good quality felt products.
