Description

   Dust removal article composed of EASYTRAP and inner gauze   

The present invention relates to dust removal articles. More specifically, the present invention relates to a dust removing article having an adhesive layer on an outer surface and a barrier layer on an inner surface.

Private or commercial buildings also need dust removal as part of their maintenance and cleaning schedule. Dust removal tools and materials are made of various structures. For example, some dust removal tools are designed to reach high or low areas. Such tools may include an extension handle with dust removal material on one end. Such dust removal materials can range from feathers to burr nonwovens. In many cases, this type of dust collector causes the dust to shift but does not actually capture the dust.

Some dusting materials using adhesives are known. For example, U.S. Patent No. 7,560,398 describes a cleaning wipe comprising a web and an adhesive material. The web defines opposing surfaces and an intermediate region between the opposing surfaces. The adhesive material is applied to the web such that a level of the adhesive material is greater than a working surface in the intermediate region. However, in some cases, the adhesive material on the opposing surfaces may adhere to a user's hand. Improvements in cleaning and dust removal tools and materials are welcome.

This disclosure provides several advantages over existing dust removal tools, materials, and articles. For example, a dust removal article according to the present disclosure may be fitted on an existing dust removal tool without damaging the surface of the dust removal tool or leaving adhesive residue on the surface of the dust removal tool. A dust removal article according to the present disclosure can be worn on one hand and can be used to collect (rather than just move) dust and particles while keeping the user's hands clean and free of dust or other residues. In some embodiments, the edges of the dust removal article can be used to clean dust in corners or gaps or other surfaces of furniture. In some embodiments, the shape of the dust-removing article allows the dust-removing article to be easily mounted on a dust-removing tool, but is still fastened and cannot easily fall off the dust-removing tool unintentionally. The invention also provides the advantage of being disposable (unlike one of the dust removal tools designed to be multipurpose). In some embodiments, the present invention does not have side bias, in other words, both sides of the dust removal article can be used for dust removal.

In one example, the disclosure includes a dust removal article. The dust-removing article includes a first material including a fluffy non-woven web, the first material forming a continuous loop having an inner surface and an outer surface, and a first end and a second end. The dust removal article further includes an adhesive layer, and the adhesive layer is at least on the outer surface of the first material. The dust removal article further includes a second material, the second material includes a barrier layer, and the barrier layer is disposed on the inner surface of the first material. The first end includes an opening.

In another example, the present disclosure includes a dust removal article, the dust removal article includes a first material, the first material includes a fluffy nonwoven web, the first material is formed with an inner surface and an outer surface, and a first One continuous ring at one end and a second end. The outer surface is treated, and the particles are attracted or collected when the outer surface is in contact with the particles; and the inner surface is untreated.

In some examples, the adhesive layer includes a pressure-sensitive adhesive or a mineral oil tackifier.

In some examples, the first material forming a continuous loop includes a seam extending from the first end to the second end.

In some examples, the seam is joined using adhesive, lamination, stitching, thermal, laser, or sonic techniques.

In some examples, the second end is joined using adhesive, lamination, suture, heat, laser, or sonic techniques.

In some examples, the joined second end forms a stiff surface.

Examples

Examples of dust removal media are prepared and tested for debris picking and towing. Functionality is shown by appropriate blocking of adhesive transfer relative to the control group and increased removal relative to the control group. These examples are for illustrative purposes only and are not intended to limit the scope of the accompanying patent application.

Test Method: Dry Debris Pickup

Each instance uses this test. The sample items were weighed before the test to obtain the pre-test weight. The test was performed using a crumb mixture, the mixture is as follows: 5 g of media test dust (can be purchased from ISO 12103-1 A3 media test dust from Powder Technologies, Inc, Arden Hills, MN)

Example items were attached to a 30.5 cm mop head (available from 3M Company, St. Paul MN, 3M EASY SCRUB FLAT MOP). A test path as shown in Fig. 9 was prepared on a vinyl composite brick floor fastened to a workbench. Path 90 is 1 'x 8' (0.3m x 2.4m) on which ¼ of the debris mixture 92 is poured at intervals of one foot (0.3m) (Fig. 1).

To perform the test, the mop head is pulled from the beginning to the end of the path, and the leading edge of the mop is reversed before the third debris pile. At the end of the path, the mop was carefully removed and weighed to obtain the post-test weight.

Subtract the pre-test weight from the post-test weight to get the amount of debris picked. This test was performed 3 times for each instance, and the equivalents were averaged. Debris pickup results are reported in grams (g). After each test, the path was cleaned for four passes using a clean duster (available from 3M EASY TRAP DUSTER from 3M Company St. Paul MN).

Drag

A Model 100 dynamometer (commercially available from Chatillon Ametek Company, Brooklyn, N.Y.) was attached to the example being tested. On each item, a 1.36 kg weight (12.7 × 15.2 cm × 2.5 cm aluminum block) was placed. The example article was then pulled by the dynamometer across the vinyl composite brick path (see above) for 1.83 meters. Record the highest value measured after 0.3 meters. This test was performed three times for each instance item, and the results were averaged. The drag result is reported in kilograms (kg).

Remove

Place each instance on a tool designed for use with it: standard 25.4cm dust collector (available from Impact Products, Toledo, OH, Lambswool Duster 3106-90), Swiffer 15.2 dust collector (available from SWIFFER 360 ° DUSTER EXTENDER from Proctor & Gamble, Cincinnati, Ohio), and Unger 61cm Dust Collector (Unger ProFlat Duster 75 is available from Unger Global, Bridgeport, Conn.). The tool is held by clamps so that the length of the handle is parallel to the ground. A DFE Ametek dynamometer (commercially available from Chatillon Ametek Company, Brooklyn, N.Y.) was attached to the top end of the example (opposite the handle). Pull the dynamometer horizontally away from the tool in a line parallel to the ground along the axis of the handle of the tool. The maximum force (in kg) that would cause the instance to be pulled away from the tool was recorded on a DFE Ametek dynamometer. The maximum force recorded is specified as the removal value for this example, and is recorded in kilograms (kg). Information reported is the average of at least three tests.

Barrier effect

Two scrub pads with a diameter of 10.2 cm (available from 3M SCOTCH-BRITE 96 General Purpose Scouring Pad from 3M Company, St. Paul, MN) were prepared. Wrap the first piece with dust removal media (available from 3M EASY TRAP DUSTER from 3M Company, St. Paul, MN), and wrap the second piece with the same dust removal media and then with non-woven gauze (HYDROPHOBIC 0.50 OSY COVERWEB WHITE (Purchased from PGI, Charlotte, NC). They were then attached to the top holder of a Frazier Schiefer uniform wear tester (available from the Frazier Company, Hagerstown, MD). A clear acrylic disk (available as Clear Acrylic GP Discs 1/8 "x 4" Dia from Crown Plastics, Inc) was attached to the bottom holder. A 2.27 kg weight was placed on top of the column and the test machine was run up to 100 cycles. After each run, the acrylic disc was removed and 5 g of crushed quartz (available from MIL-AV-E-8593F Crushed Quartz from Powder Technologies, Inc, Arden Hills, MN) was sprinkled on one of the pads in contact with the pad. side. Then shake the disc against the inside of the trash can and tap the disc to remove any unattached quartz. If there is quartz adhered to the surface, the test is classified as a failure. The results are shown in FIG. 10. The disc 100 on the left shows the adhesion of quartz to the surface of the disc, which illustrates the amount of adhesive transfer that occurs without a barrier. The disk 102 on the right shows the surface of the disk in the context of using a barrier layer.
