    摘要: A method for grounding reinforcement (12) and composites (17) on a calender line reduces static build up on the composite (17), and makes it possible to subject a wire reinforced composite to electron beam processing (EBP). The method employs a slip ring (36) attached to rolls which contact composite (17) on the calender (11), and reinforcement (12) before it reaches the calender (11), wherein the slip ring (36) rotates with the rolls while the rolls are working polymer into the reinforcement, and a terminal (34) connected to the slip ring (36) remains stationary, and the terminal (34) is attached to ground (27). The method effectively grounds the composite as well as the reinforcement to prevent electrical discharge during EBP.

    摘要: The invention relates to a fibrous acoustical material for reducing noise transmission. This fibrous acoustical material comprises first, second and third fibers. The first fiber has a first fineness of 1.5-20 deniers and a first softening point. The second fiber has a second fineness of 1.5-15 deniers. At least a surface of the second fiber has a second softening point which is at least 30° C. lower than the first softening point. The third fiber has a third fineness of 1.5-15 deniers. At least a surface of the third fiber has a third softening point which is lower than the second softening point and at least 80° C. lower than the first softening point. The first, second and third fibers are respectively in amounts of 10-90 wt %, 5-85 wt % and 5-85 wt %, based on a total weight of the first, second and third fibers. The first, second and third fibers are each within a range of from 20 to 100 mm in average fiber length. The fibrous acoustical material has an average apparent density of from 0.01 to 0.8 g/cm3. The fibrous acoustical material is light in weight and superior in acoustical capability, heat resistance and resistance to compressive force.
