Problems solved by technology

Even in the case of wet use, since the abrasive particles are peeled off after the water-soluble binder is dissolved in the solvent, it takes a while until the abrasive particles are peeled off.

Embodiment Construction

[0021] Below, while referring to the attached Figure 1 The present invention will be described based on preferred embodiments of the present invention. figure 1 and figure 2 The cleaning sheet 1 of the embodiment shown is suitably used for cleaning of hard surfaces. The cleaning sheet 1 is a dry type, and does not substantially contain liquid components such as cleaning liquid. "Substantially not containing" means that the ratio of the liquid component in the cleaning sheet 1 is 3% by mass or less. The cleaning sheet 1 has a liquid retaining layer 4 and an air-laid layer 5 . That is, the cleaning sheet 1 has a two-layer structure including the liquid holding layer 4 and the air-laid layer 5 . Therefore, no other layer is interposed between the liquid retaining layer 4 and the airlaid 5 . However, this does not prevent other layers from being interposed between the liquid-retaining layer 4 and the air-laid layer 5, and may also be interposed between the liquid-retaining ...

Abstract

This cleaning sheet (1) comprises a laminate of a liquid holding layer (4) and an airlaid layer (5) disposed on one side of the liquid holding layer (4). The airlaid layer (5) includes large-diameter fibers (2) having a denier of 10 to 150 dtex and small-diameter fibers having a denier of 0.5 to 5 dtex. A plurality of tips of large-diameter fibers (2) are present on the surface of the airlaid layer (5) and provide abrasiveness and scraping properties against soil on a surface to be cleaned. Also, a plurality of tips of large-diameter fibers (2) are present on the surface of the liquid holding layer (4) opposite to the surface facing the airlaid layer (5), and the number thereof is less than the number of tips of large-diameter fibers (2) present on the surface of the airlaid layer (5).

Description

technical field [0001] The present invention relates to a cleaning sheet. Background technique [0002] The applicant previously proposed a cleaning sheet comprising 10 to 90% by mass of thermoplastic fibers with a fiber length of 2 to 15 mm and a fineness of 10 to 150 dtex, and 10 to 90% by mass of cellulose-based fibers. There are many front ends of the thermoplastic fibers, which have abrasiveness or scraping properties on the dirt present on the surface to be cleaned (Patent Document 1). This cleaning sheet has a feature that it has sufficient abrasiveness or scraping ability against dirt. [0003] As other cleaning articles that are abrasive to dirt, an abrasive cleaning article is proposed in Patent Document 2, which includes a base material, a water-soluble adhesive, and a cleaning material releasably fixed to the base material by the water-soluble adhesive. Multiple abrasive particles. Regarding this abrasive cleaning article, when the abrasive particles come into...
