A cleaning toolhaving at least one side openingand a cleaning rollat a cleaning head, wherein a dust guide surfacefor leading dust from a surface to be cleaned to the side openingis provided along a lower end of the side opening; the cleaning rollis formed of an elastic roll having a surface covered with a thin film, and is rotatably arranged in a position to close the side openingand to be in contact with the surface to be cleaned; and the cleaning rollrotating according to movement of the cleaning headtakes the dust through the dust guide surfaceinto the side openingwhile pushing the dust against the surface to be cleaned.

Cleaning tool

A cleaning sheet (A) includes: a substrate sheet (); and a plurality of long-fiber bundles () provided thereon, each long-fiber bundle () being made by aggregating long fibers (), the long-fiber bundles () being arranged side-by-side and joined to the substrate sheet (). Each long-fiber bundle () is joined together by fiber-joining sections (). Each long-fiber bundle () is joined to the substrate sheet () by sheet-joining sections (). Each sheet-joining section () is provided so as to overlap one of the fiber-joining sections (). Each long-fiber bundle () has been cut by linear cut sections (), each linear cut section () being formed in a region between adjacent sheet-joining sections (). Each long-fiber bundle () includes cut fibers () and uncut fibers ().

Cleaning sheet

The invention provides a means capable of effectively inactivating and removing allergen or a precursor thereof. The invention relates to an allergen-reducing agent containing water and a water-soluble polymer compound having units having hydroxy or carboxy groups wherein at least a part of hydrogen atoms of the hydroxy or carboxy groups are substituted by specific groups containing a polyether group.

Allergen depressant and depression method

The invention relates to an allergen remover composition containing component (a): an organic compound forming an azeotropic mixture with water and having an azeotropic point of lower than 100&#xb0; C. with water at 1013.25 hPa, component (b): a component which upon evaporation of a liquid component in the allergen remover, forms a solid containing a compound represented by the following general formula (1) or component (b'): a combination of potassium ion, sodium ion and sulfate ion at a potassium ion/sodium ion molar ratio of from 2/8 to 9/1 and component (c): water.KNa(SO)&#x2003;&#x2003;(1)wherein x is a number of 0.8 to 3.6, y is a number of 0.4 to 3.2, and x+y is 4.

Allergen remover

A magnetic recording medium comprising a nonmagnetic substrate, an intermediate layer provided on the nonmagnetic substrate, and a magnetic layer provided on the intermediate layer, wherein the magnetic layer contains, as a lubricant, (A) a fatty acid ester derived from a straight-chain or branched aliphatic alcohol having 3 to 7 carbon atoms and a straight-chain or branched fatty acid having 12 to 18 carbon atoms and (B) a fatty acid ester derived from a straight-chain or branched aliphatic alcohol having 8 to 14 carbon atoms and a straight-chain or branched fatty acid having 12 to 18 carbon atoms.
