This multi-purpose polyester fabric is a non-woven material, somewhat similar to an interfacing fabric. It is available in two weights and we constantly use them in our studio in a variety of ways. The mediumweight is useful as a support material in vacuum table work and for pulp spraying. We also use it in our drying system, putting the wet sheets between 2 layers of mediumweight polyester, to keep the blotters clean. The mediumweight is also a perfect couching weight for Asian style papermaking.
To clean the polyester felts, simply hose them off with water, and allow to dry.
