Abstract
A method of manufacturing a cleaning member includes a fiber bundle conveying step conveying a fiber bundle to a merging section, a nonwoven fabric conveying step conveying the nonwoven fabric strips to the merging section; a multilayer web forming step forming a multilayer web by overlaying the fiber bundle on the nonwoven fiber strips at the merging part; and a joining step joining the fiber bundle and the nonwoven fabric strips to each other in the multilayer web. In the fiber bundle conveying step, the fiber bundle is conveyed at a tension at which there is no width shrinkage in the fiber bundle, and in the multilayer web forming step, the multilayer web is formed by overlaying the fiber bundle on the nonwoven strips while applying a tension that does not cause width shrinkage in the fiber bundle.
