    • A cleaning sheet including a base sheet and at least one surface layer of filaments placed on the base sheet is described. The filaments extend in one direction and each of the filaments extends over the whole length of the surface layer in the extension direction of the filaments. The base sheet and the surface layers are bonded to each other at a plurality of bonding lines intersecting the extension direction. The surface layer includes a plurality of filaments-holding regions, each of which includes at least one end of the bonding line other than the bonding lines forming the filaments-holding region. Accordingly, in the filaments-holding regions, differences-in-level for collecting dust are formed and gaps (pockets) for capturing the dust therein are exposed.
    • 描述了包括基片和布置在基片上的至少一根细丝表面层的清洁片。 长丝在一个方向上延伸,并且每根细丝在长丝的延伸方向上在表面层的整个长度上延伸。 基片和表面层在与延伸方向相交的多个接合线上彼此接合。 表面层包括多个长丝保持区域,每个长丝保持区域包括不同于形成长丝保持区域的接合线的接合线的至少一个端部。 因此,在灯丝保持区域中,形成用于收集灰尘的水平差,露出用于捕获灰尘的间隙(袋)。
