Definitions

  • the present disclosure relates to a composite surface cleaning article, useful for cleaning a variety of different surfaces.
  • a wide variety of cleaning implements are known to aid in the cleaning of a variety of surfaces. Such implements include brushes, scrubbing pads, scrubbing cloths and the like. Many of such implements are designed to be disposable, washable or replaceable.
  • An example of a replaceable cleaning implement is a mop which contains a re-usable handle and a detachable mop head which can be removed and either washed or replaced by a new detachable mop head.
  • Pads containing 3 zones are disclosed.
  • the pads comprise an assembly zone comprising a low density, open non- woven fibrous structure, a supporting zone adjacent to the assembly zone comprising an intermediate density, open non-woven fibrous structure, and a cleaning zone adjacent to the supporting zone comprising a high density, open non- woven fibrous structure and abrasive.
  • Also disclosed are methods for preparing a pad comprising assembling a non- woven fiber web with a thickness and a first side and a second side, roll coating the fiber web in a 2 roll coater with a first thermosetting adhesive liquid, spray coating the first side of the fiber web with a second thermosetting adhesive liquid which has a lower viscosity than the first thermosetting adhesive liquid, such that the adhesive penetrates no more than 66% of the non- woven fiber web thickness, spray coating the first side of the fiber web with abrasive particles, such that the abrasive particles penetrate no more than 33% of the non-woven fiber web thickness, and curing and/or drying the fiber web.
  • Surface cleaning articles comprise a composite assembly comprising a base member comprising a glove or mitten comprising an array of hooks on a portion of an outer surface, and a three zone pad comprising an assembly zone comprising a low density, open non- woven fibrous structure suitable for joining with the hooks of the base member, a supporting zone adjacent to the assembly zone comprising an intermediate density, open non-woven fibrous structure, and a cleaning zone adjacent to the supporting zone comprising a high density, open non- woven fibrous structure and abrasive, wherein the pad is removably attached to the base member.
  • Methods for cleaning a surface comprise assembling a surface cleaning article, comprising providing a base member comprising a glove or mitten comprising an array of hooks on a portion of an outer surface, and providing a three zone pad comprising an assembly zone comprising a low density, open non- woven fibrous structure suitable for joining with the hooks of the base member, a supporting zone adjacent to the assembly zone comprising an intermediate density, open non- woven fibrous structure, and a cleaning zone adjacent to the supporting zone comprising a high density, open non-woven fibrous structure and abrasive, wherein the pad is removably attached to the base member, attaching the assembly zone of the pad to the hooks of the base member, and wiping a surface with the surface cleaning article.
  • Figure 1 shows a cross sectional view of a pad of the present disclosure.
  • Figure 2 shows a base member of the present disclosure.
  • Figure 3 shows a base member of the present disclosure.
  • Figure 4 shows a composite cleaning article of the present disclosure.
  • a wide variety of cleaning implements are know to aid in the cleaning of a variety of surfaces.
  • Such implements include brushes, scrubbing pads, scrubbing cloths and the like.
  • Such implements are designed to be grasped or held by the user when used.
  • grasping or holding a cleaning implement can become difficult, especially if done for long periods of time.
  • the wearing of a glove can make it more difficult to grasp cleaning implements such as brushes, scrubbing pads, and the like. Therefore it is desirable to have a cleaning implement which includes a glove or mitten for protection and has a built in, but replaceable, cleaning implement which can be used without having to be grasped or held by the user.
  • a composite surface cleaning article which comprises a base member that is a glove or mitten which has an array of hooks on a portion of the outer surface and a multilayer cleaning pad which is removably attachable to the glove.
  • the pad may be removed from the base member, washed and reattached or discarded and replaced by a different pad.
  • base member refers to a glove or mitten.
  • a glove is a fitted covering for the hand with a separate sheath for at least one finger and the thumb, typically a glove has a separate sheath for each finger and the thumb.
  • a mitten is a covering for the hand that encases the thumb separately and the four fingers together.
  • pad refers a multilayer fibrous construction useful for cleaning a surface.
  • the term "removably attached" when dealing with composite cleaning articles means that the pad can be attached to the base member, removed from the base member and reattached to the base member repeatedly.
  • non-woven refers to a web or batt of random or directional fibers held together through mechanical, chemical, or physical methods, or any combination of these; but does not include weaving, knitting, stitching traditional felting as well as conventionally formed paper.
  • low density when dealing with a non-woven web refers to an extremely open structure having an extremely high void volume.
  • intermediate density and high density are relative to the above defined low density.
  • the term "open" when dealing with a non-woven web refers to a web structure that has interspersed spaces.
  • One method for characterizing an open web is that, for a web thickness of about 6 millimeters (one quarter inch), when held up to a light the web is highly translucent or even transparent to a viewer's eyes, i.e. substantially all of the light registering on the viewer's eyes passes through the web structure.
  • the pad which attaches to the base member described below comprises three zones.
