Entangling sheets with a high degree of freedom to increase fiber density,
Although a bulky sheet having a large number of irregularities formed on the surface is effective, there is a problem that it is not possible to sufficiently collect fine dust such as soil dust. In addition, in order to maintain the strength and shape retention required for a cleaning sheet, and to satisfy both the degree of freedom of fibers required to enhance dust collection performance, insert a net manufactured in a separate process between fibers, A means for performing secondary embossing on a sheet once manufactured is often used.
