Description

  The present invention relates to a wiping material that can be cleaned using a tufted portion by a single fiber layer in which single fibers are gathered in a substantially parallel shape to form a layer shape having a required thickness.

  Japanese Patent Application Laid-Open No. 2002-369883 (Patent Document 1) discloses a cleaning article characterized in that a brush portion is formed of a plurality of strips formed of a soft sheet and elongated and a fiber bundle. It is disclosed. In this cleaning article, since the brush portion is formed of a strip piece and a fiber bundle, the fiber bundle is less likely to be entangled or rounded, and the shape retention of the brush portion can be improved. When the fiber bundle is partially joined, the rigidity of the fiber bundle forming the brush portion can be increased, and the fiber bundle can be prevented from curling or shrinking even after long-term use. ing.

Such cleaning articles are mostly premised on disposable, but it is possible to use a wiping material holder that can hold a sheet-like cleaning material, which is the most common form of disposable cleaning material. This is not possible, and a wiping material holder other than the conventional wiping material holder must be used separately. In addition, with respect to dust such as groove portions, other concave portions, and corner portions, it may be difficult to obtain a sufficient scraping effect with a strip formed from a soft sheet.

  In the wiping material A shown in FIGS. 1 to 4, the heat-meltable single fibers 10 having a substantially constant length (not necessarily required to have a constant length) are arranged substantially in parallel (single fibers on the end side). As long as the tuft-shaped part is formed, the single fibers may be entangled to some extent.) A predetermined length with the required thickness (perpendicular to the plane of the drawings in FIGS. 1 and 2) , The longitudinal direction in FIG. 3) and a single fiber layer 12 having a planar rectangular layer shape, and a length longer than the single fiber 10 (not necessarily long), and the predetermined length is long. A non-woven fabric 14 made of rectangular hot melt fibers (may be a non-woven fabric composed of hot melt fibers and non-heat melt fibers and having heat melt properties as a whole. 1 may be laminated, as shown in FIG. Layer was (sides of the nonwoven fabric 14 is configured to have an expanded portion 14a that has spread to the single fiber 10 both sides of the monofilament layers 12 [free end]) may be prepared using.

  At a pair of symmetrical positions across the center in the direction of each single fiber 10 (left-right direction) of this laminate, the single fiber layer 12 is formed by a pair of heat-sealing wires 16 orthogonal to each single fiber 10 over the entire length direction. All the single fibers 10 and the nonwoven fabric 14 are heat-sealed in the thickness direction as indicated by arrows. As a result, the outer portions of the two heat-sealing wires 16 in the single fiber layer 12 each constitute a tufted portion 18, and both ends are heat-sealed between the two heat-sealing wires 16 in the single fiber layer 12. The substantially parallel single fiber group 20 is comprised. In addition, the formation position of such a heat sealing | fusion wire 16 is not necessarily restricted to a symmetrical position. Further, the heat-sealing wire 16 is not limited to one orthogonal to the single fiber 10, and is not limited to a straight line but may be a curved line or a wavy line. Moreover, the heat-sealing wire 16 does not need to be continuous in the length direction.
