IPC: D01D5/36
Filed: 1984-07-04
Abstract: PURPOSE:The titled fiber that is composed of 2 kinds of fiber-forming synthetic polymers having different melting points from each other in a specific arrangement, thus showing thermal fusibility and improved liquid-holding properties by fusion of the lower-melting component. CONSTITUTION:Component A is mixed with 20-50wt% of component B which has a melting point more than 30 deg.C lower than the melting point of component A. Component B is flat in its cross section, extends almost in parallel along the fiber axis in the form of stripes of polymer bands of uncertain forms. Further, at least one of component B runs from the fiber surface through the hollow part. The percentage of the hollow part is 10-40% in the fiber cross section and the fineness of the filaments is 1.5-30 denier. The self-tacking properties of component B enables the production of hot-melt type nonwoven fabrics and the melt flow of the component B reaching the hollow part forms slits to increase liquid holding.

Abstract: PURPOSE:To uniformize the thickness of the film on a cylinder, by imparting temp. difference between the upper and lower parts of a cylinder to be coated so as to make the temp. of the upper part of said cylinder higher than that of the lower part thereof and applying paint to the cylinder to prepare an electrophotographic photosensitive body. CONSTITUTION:Temp. difference is imparted between the upper and lower parts of a cylinder to be coated so as to set the temp. of the upper part of the cylinder higher than that of the lower part thereof and paint is applied to the cylinder to prepare an electrophotographic photosensitive body. Only the upper part of the cylinder is raised in temp. by preliminarily heating only the upper part of the cylinder in the outside and this heated cylinder may be set to a coating apparatus to perform coating. However, practically, a method for incorporating a heater in the cylinder support mechanism itself of the coating apparatus is simple and temp. stability is enhanced. Since the temp. of an atmosphere is kept constant by employing this method, the uniformity in the thickness of the film to be continuously applied to the cylinder is enhanced.
