Provided is a space filling material having excellent strength in reinforcing a predetermined space to be filled with the space filling material and/or strength in fixing a material to be fixed therewith. The space filling material (11) includes reinforcing fibers and a thermoplastic resin, wherein the reinforcing fibers form a plurality of intersections at least a part of which are bonded with the thermoplastic resin, and among all of the reinforcing fibers, a proportion in volume of reinforcing fibers each having a bent ratio of 1.004 or higher is 20 vol % or more relative to a total volume of the reinforcing fibers, the bent ratio being defined as a ratio of fiber length/shortest distance between opposite ends of fiber. The space filling material (11) expands to fill a predetermined space (13) when the thermoplastic resin is softened by heating to release bending loads of the reinforcing fibers.

In some implementations, printer roller cleaning sheets may include a nonwoven fabric having a blend of polyester fibers and cellulose fibers, the nonwoven fabric being in the form of a continuous sheet wound around a core, the nonwoven fabric designed and configured to effectively remove debris from printer rollers, the roll of polyester cellulose material configured to replace a roll of paper in the printer in order to perform a cleaning function of the one or more printer rollers.

A process for the production of a nonwoven fabric. In particular, it relates to the production of a nonwoven fabric having desirable tactile and haptic as well as mechanical properties, as well as to the nonwoven fabric itself. The process requires the selection of specific polylactic acid polymers and corresponding process conditions.
