Summary: | PURPOSE:To provide an apron and a condenser for woollen spinning, having antistatic properties and capable of imparting sufficient 'rubbing' performances to a web. CONSTITUTION:This apron is a cylindrical molded body 4 composed of a laminate of a tensioning body layer 1 composed of a rubber-coated woven fabric, a cord layer 2 for improving the elastic modulus and an outer layer rubber 3, covering the cord layer 2 and laminated onto the tensioning body layer 1. The rubber-coated woven fabric in the tensioning body layer 1 comprises warp or weft yarn parallel in the circumferential direction of the cylindrical body and the cord layer for improving the elastic modulus comprises cords composed of natural or synthetic fiber, and the cord layer is crossed at 30-45 deg. angle to the warp or weft yarn of the woven fabric and arranged in a wrapped state at a pitch of an equal space in (3:10) to (5:10) ratio of the diameter of the cords 2 to the thickness of the outer layer rubber 3. The rubber composition constituting the rubber-coated woven fabric has <=1 MOMEGA electric resistance and the rubber composition in the outer layer rubber is a bright color rubber composition having <=1,000 MOMEGA electric resistance. |
