    Abstract: A friction material has a resin amount distribution that is the largest at a portion near a non-friction surface, that becomes lower toward an inside and that is the lowest at a portion near a friction surface. For example, such friction material is manufacture as follows. First, two friction materials are overlapped while the friction surfaces faced with each other. Then, the friction materials are dried at a room temperature. At this time, the resin has such a characteristic as to move while dragged by a solvent that dries from the non-friction surface located outside. Using such characteristic, the resin amount at the portion near the friction surface is lessened. Then, a temperature at the friction surface is made low and a temperature at the non-friction surface is made high in a drying step of the friction material. Thereby, the resin amount at the portion near the friction surface is lessened.

    Abstract: An industrial fabric used in the manufacture or processing of at least one material web includes a base fabric having a board side and a machine side. The base fabric includes a plurality of spirals extending in a cross machine direction (CMD). The spirals are interconnected together with each other along adjacent peripheral edges to form a spiral link fabric. The base fabric has opposite lateral side edges extending in a machine direction (MD). One or more electrostatic control yarns are positioned within a corresponding spiral and extend in the CMD direction to the lateral side edges. A pair of conductive edge coatings is applied to at least the board side of a respective lateral side edge for a predetermined width. The conductive edge coatings and the one or more electrostatic control yarns form an electrostatic grid. A traction coating covers substantially all of at least the board side of the base fabric, but does not cover the pair of conductive edge coatings. The traction coating has a coefficient of friction greater than approximately 2 on the board side. The industrial fabric has a completely non-marking seam because of its integral nature with the base fabric and the equal amount of traction coating at the seam compared with rest of the fabric.
