Disclosed is a sponge roller (1) which comprises: a generally cylindrical roll body (3) which is formed from a porous polyvinyl acetal resin material that is elastic in a wet state; and a plurality of projections (5) which are integrally formed on the outer circumferential surface (3a) of the roll body (3). The sponge roller (1) cleans a surface to be cleaned by bringing the plurality of projections (5) into rotary contact with the surface to be cleaned. The polyvinyl acetal resin constituting the sponge roller (1) has an anionic functional group.
Roll bodies (3) consist of a porous material having elasticity in a wet state. Rotating shafts (2) of the roll bodies (3) are inserted through inner diameter sections of the roll bodies (3) and fixedly support the roll bodies (3). When the rotating shafts (2) are rotated and flat surfaces (11) to be cleaned, which are arranged substantially parallel to the rotating shafts (2), are rotated about an imaginary rotation axis (12) provided in an imaginary plane substantially perpendicular to the rotating shafts (2), outer peripheral portions of the roll bodies (3) make rotational contact with the rotating surfaces (11) to be cleaned, causing the roll bodies (3) to perform scrub cleaning of the surfaces (11). The outer peripheral portions of the roll bodies (3) each include a center region (6) making contact with that inner region (13) of a surface (11) to be cleaned which is near the imaginary rotation axis (12) and also each include outer end regions (7) making contact with that outer region (14) of the surface (11) to be cleaned which is spaced from the imaginary rotation axis (12). The contact strength, during one rotation of the roll bodies (3), of the outer peripheral portions of the roll bodies (3) with the surfaces to be cleaned is set such that the contact strength in the center region (6) is lower than the contact strength in the outer end regions (7).
A sponge roller (1) for cleaning has a substantially cylindrical roll body (3) consisting of a polyvinyl acetal based porous material and exhibiting elasticity in a wet state, and a plurality of protrusions (5) integrally formed on the outer circumferential surface (3a) of the roll body (3), and cleans a surface to be cleaned by bringing the plurality of rotating protrusions (5) into contact with the surface to be cleaned. The outer surface of a protrusion (5) has a top outer surface (internal exposed surface) (5a) which is in contact with the surface to be cleaned during cleaning, while exposing the internal texture of the protrusion (5).
The problem that in the use of a central core covered with sponge roller in cleaning, with the passage of time, the sponge roller twists in a rotational direction (circumferential direction) and slips in an axial direction to thereby cause nonuniformity in cleaning is solved. There is disclosed an approximately cylindrical central core (1) for cleaning sponge roller having an axially extending internal hole (2) and multiple small holes (3) realizing communication from the internal hole to the circumferential external surface. The central core for cleaning sponge roller is characterized in that the external surface of the central core is provided in the circumferential direction with multiple axially slender projections (4) and that the projections (4) each have an axial section viewed from a direction perpendicular to the axial direction that is not flat (5A,5B).
A core for a cleaning sponge roller and a cleaning sponge roller set include a core and a cleaning sponge roller mounted on the core. The core for the cleaning sponge roller is in a substantially cylindrical shape including a bore extending in an axial direction and a plurality of small holes communicating between the bore and a circumferential outer surface of the core. The diameter of the bore is 10 mm or more. The diameter of the small holes is 2.5 mm or more. A total of cross-sectional areas of openings of all the small holes is larger than a cross-sectional area of the bore.
