Abstract

A drying mat having an open-hole mesh with jersey backing top layer and a terry cloth bottom layer.

Description

BACKGROUND OF THE INVENTION

1. Field of the Invention
This invention relates to drying mats, and in particular to bonding two or more layers into a drying mat constructed to provide for fast drying of persons, animals or objects while providing a surface for receiving the persons, animals or objects or subjects which prevents damage or discomfort to the persons, animals or objects.
2. Description of the Prior Art
Drying mats for people, animals and objects are well known in the art. These drying mats include one layer of absorbent material for receiving wet objects such as both dinnerware and silverware after being washed, fruit or vegetables after being washed and wet persons and animals after they have been washed, caught in the elements or after swimming. There are one-layer materials including different types of paper and various textiles such as terry cloth. These types of one-layer materials often receive water drippings which drippings are either absorbed to cause the one-layer material to remain wet, or to transfer the water drippings to the counter, floor or other support surface upon which the one-layer material is resting. These one-layer materials usually provide a damp surface which can cause damage to the support surface or to make the support surface become slippery causing possible damage or injury due to slipping or falling, and provide an environment for the presence of unhealthy microbes or other disease-causing matter. Furthermore, the one-layer drying mats often remain damp or wet, causing the object, person or animals resting upon them to remain partially damp or wet, and further leaving an odoriferous atmosphere after use.
Multi-layer drying mats are also known. These can be two-layer mats, but usually include at least three-layer drying mats composed of at least three layers for receiving wet people, animals or objects, and receiving water drippings therefrom and absorbing such water drippings to facilitate the drying of the objects, persons or animals. For example, U.S. Patent Publication Nos. 2010/0143640, 2010/0143645 and 2010/0209661 (all to Wilmsen, 2010) each describes a drying mat which respectively includes a first microfiber layer and a second microfiber layer sandwiching a foam layer, the layers being held together by adhesive layers between the respective foam layer and the respective microfiber layers. A binding around the perimetrical edges of the microfiber layers and the foam layers assist in attaching them together. The microfiber layers allegedly have a soft and cushioning nature which cushions stemware and glasses and protects countertops from dishes and cookware while drying. The microfiber also allegedly has a wicking action. The foregoing microfiber is non-woven. It has a honeycomb or other pattern for increasing the surface area of the drying mat. The foam layer allegedly serves the purpose of absorbing water and cushioning dishes placed thereon. The microfiber layers have honeycombed surfaces to increase their absorbency by reason of their wicking action and by reason of gravity. To produce the foregoing product, the microfiber layers are bonded to the foam layer by heat compression, and the binding material is connected to the laminate material by sewing. A shortcoming of the foregoing type of drying mat is the requirement that it has three layers, and there is no structure suggested for making the foregoing mats attractive when in use. Another shortcoming is limited absorbent capacity of the microfiber material. Although the foregoing drying mat allegedly can absorb four to five times its own weight in water, there is no allegation that the foregoing drying mat retains such absorbed water. Therefore, water can ooze from the drying mat or be forced therefrom by the weight of dishes, glasses, a person, etc., disposed thereon, causing possible damage to the surface upon which the drying mat rests which and possibly re-wets the dishes, glasses, person, etc., disposed thereon. A serious shortcoming is that these prior drying mats become odoriferous following use, and they fall apart upon repeated washings. Importantly, there is no provision in the foregoing drying mat that permits air flow in the mat for evaporating moisture absorbed in the mat, causing the above-described mat not to dispense the absorbed moisture. The foregoing drying mats presently on the market are three-ply having matching top and bottom layers using polyester woven into a waffle-type weave (called “waffle dobby”), and its middle portion is an inexpensive polyurethane foam.
Other drying mats are also known. There are various disposable drying mats usually composed of cellulose material such as absorbent paper products, but these can be cumbersome to store and discard, and are not frequently used for aiding in the drying of dishes and the like, nor for assisting in the drying of persons or animals. Disposable drying mats are discussed in U.S. Pat. Nos. 2,251,372 (Nicholson 1941), 3,616,134 (Palenske 1971), 4,328,275 (Vargo 1982) and 7,208,216 (Ackerman 2007), and in U.S. Patent Publication 2006/0093788 (Behm et al. 2006). Another disposable mat for absorbing oil and other liquids is U.S. Pat. No. 5,500,267 (Canning 1996), which is composed of a plastic sheet with an oil-absorbing layer and additional layers.
As mentioned above, there are known a couple of one-layer towels (not drying mats) composed of something more than plain terry cloth. These include U.S. Pat. Nos. 6,961,969 (Nichols 2005) and 7,137,157 (Nichols 2006) which disclose towels with an absorbent base layer and non-absorbent projections.
There were also four patents located describing mats having two layers. A two-layer sorbent article is described in U.S. Pat. No. 5,733,629 (Insley 1998) having a sorbent layer with a texturized polymeric skin layer secured to a surface of the sorbent layer to give the article a non-slip property. U.S. Pat. No. 6,579,816 (Lockett 2003) describes a cut-resistant and shred-resistant absorbent sheet having an absorbent and cut- and shred-resistant layer and a base layer. In U.S. Pat. No. 6,774,067 (Demott et al. 2004), there is described a mat having micro-knitted plush polyester fabric to which is bonded a rubber backing.
There are included in known mat constructions complicated drying mats having many layers (four or more) with presumably added manufacturing costs. The latter drying mats are discussed in U.S. Pat. Nos. 5,962,350 (Krotine 1999—a floor mat), 6,899,940 (Leriget 2005) and 6,911,407 (Sherrod et al 2005).
Also known are drying mats having three layers. One such mat is the subject of U.S. Pat. No. 7,067,174 (Carkeek 2006) which discloses a mat having a non-slip backing layer, a top absorbent layer and an intermediate stabilizing layer. U.S. Patent Publication 2004/0229535 (Tang 2004) describes an anti-slide mat having a woolly layer, a base layer and an anti-slide layer formed with an anti-slide paste. U.S. Pat. No. 4,684,562 (Hartkemeyer 1987) has a cardboard layer that is liquid absorbent and permeable, a liquid absorbent, cork intermediate layer, and a liquid-resistant, foil protected bottom support layer.
There are also other patents disclosing products which may be of general interest although they are not relevant to drying mats. A container, shelf or drawer liner is explained in U.S. Pat. No. 6,926,862 (Fontenot et al. 2005) as having a liquid impervious layer and an absorbent layer containing a material for controlling odors. U.S. Pat. No. 7,208,216 (Ackerman 2007) is directed to a disposable cutting sheet for use with food items and has a cut-resistant layer made of apertured thermoplastic ply, an absorbent ply and a liquid-impervious layer.
Included in the latter group of patents are yoga and exercise mats. A composite yoga mat and straps is described in U.S. Pat. No. 7,485,071 (Edwards 2009) and its divisional U.S. Publication 2005/0192158 (2005), which disclose a product composed of an absorbent terry cloth or other absorbent sheet embedded on one side with a flexible foam coating of frictional material for protecting the flooring from sweat, and to prevent moisture from moving up out of the ground when the mat is used outside. The foam allegedly provides a cushioning effect. U.S. Publication 2004/0250346 (Vasishth 2004) describes an anti-slip, multi-layer exercise mat having an upper fabric layer, a lower pliable foam layer and an intermediate adhesive layer.
There are presently no known drying mats composed of two plies which are bonded together which provide both for air circulation and are very absorbent. Furthermore, no such construction of drying mats is known which prevent substantial water penetration and are economical to make and use. The inventor is also unaware of drying mats having a three-ply construction which enable air circulation, are very absorbent, and provide a cushioning effect to prevent damage to either persons or animals or objects placed thereon and to protect the counter, floor or other surface for supporting the drying mat.

SUMMARY OF THE INVENTION

It is an object of the present invention to provide a drying mat which both enables the circulation of air therethrough and provides for the absorption of water.
It is also an object of the present invention to provide a drying mat for drying of dishware, dinnerware and cookware, including dishes, glasses, stemware, eating implements, cooking implements and the like which is water absorbent, protects countertops from both chipping damage and water stains and enables the draining of objects placed thereon without subjecting such objects to damage by being chipped, broken or scratched due to being tipped over or against other objects, this feature being due to thickness and cushioning effect of the drying mat.
Another object is to provide a drying mat for persons or animals which provides great water absorbency, air circulation, and limits water penetration therethrough to protect the floor, countertop or other supporting surface for the drying mat against water stains.
It is another object to provide a two-ply laminated drying mat which is effective in operation, durable, washable and inexpensive to produce.
A further object of the present invention is the provision of a drying mat which is highly water absorbent yet provides for sufficient evaporation to prevent the drying mat from being saturated or retaining excessive moisture which would prevent the objects, or persons or animals disposed thereon from remaining wet or damp.
It is still an additional object of the present invention to provide a drying mat for cushioning objects, or persons or animals placed thereon which is absorbent, durable, does not retain absorbed water, limits the flow of water therethrough, is protective of both persons or animals and objects disposed thereon and is protective of the surface supporting the drying mat.
Yet still an additional object of the present invention is the provision of a drying mat having the provisions discussed above which can be provided with attractive colors and designs.
It is also an object of the present invention to provide a drying mat with a highly water absorbent characteristic and is attractive, durable and resists water penetration therethrough.
These and other objects are achieved by the invention described hereinafter and from the appended claims.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

According to a preferred embodiment of the invention, a drying mat is provided composed of a knit double-face, open-hole mesh with a jersey backing and a double-faced terry cloth layer for absorbing water. The open-hole mesh with a jersey backing both absorbs water and enables air circulation within the mat to evaporate water from the terry cloth layer. The drying mat also has a border binding for securing the open-hole mesh with jersey backing layer and the terry cloth layer. An important aspect of the present invention is the bonding of the two layers together, yielding a very efficient and effective drying mat. The drying mat of the present invention is unusually beneficial for its drying function due to the unique placement of the holes of the open-hole mesh to allow for any fluid and moisture movement while the portions of the top layer lacking holes supports objects, persons or animals on top of the drying mat. Drying mats according to the present invention enable air to circulate in the mat to evaporate moisture absorbed or otherwise in the mat causing it to dry unusually quickly.
FIG. 1 shows a drying mat 10 according to one embodiment of the invention. Drying mat 10 has an opposing open-hole mesh with jersey backing top layer 14, and a double-faced terry cloth bottom layer 12 which is shown as being visible due to a rolled-up corner 16 of drying mat 10. Open-hole mesh with jersey backing top layer 14 and terry cloth bottom layer 12 are joined together by bonding. A decorative binding 18 is attached to layers 12 and 14 by means of stitching 20 for covering loose edges of the bonded fabrics. While FIG. 1 shows open-hole mesh with jersey backing layer 14 as being the top or upper layer and terry cloth bottom layer 12 as being the bottom or lower layer, these could in fact be reversed so that the open-hole mesh with jersey backing layer 14 is the bottom layer and layer 12 is the top layer. However, it has been found that the preferred embodiment is that as shown in FIG. 1.
Referring to FIGS. 2 and 3, double-face terry cloth bottom made of a double-sided knitted terry bottom layer 12 terry which is made on a circular knitting machine that knits the material course by course with defined loop sizes in a continuous tubular form, which is cut into a flat material prior to heat setting the terry material at a specified width that determines the thickness and weight of the material. Terry cloth knitwear is usually manufactured using multiple yarns. The terry loops are interconnected or knitted jointly with the ground yarn into the base fabric. That is, the terry loop fabric has terry loops on both the front and back surfaces and in which the front loop and the back loop are inter-knitted. The construction of the terry cloth bottom layer 12 in the preferred embodiment is made from uniquely blended yarns of 100D/18F×150D/144F (these relate to the yarn size and filament count in the two transverse directions) with an overall content of 88% biconstituent fiber and 12% polyester. Biconstituent fiber is a blended yarn of 78% micro-polyester and 22% polyamide nylon (sometimes called microfiber or micro-filament yarn). The micro-filament yarn blended with the polyamide nylon has many performance attributes, like better wicking, absorbing moisture quickly and very fast drying as compared to cotton. The loop sizes allow the wicking transfer from the surface, and moisture is held in the drying mat until the drying mat is dry.
FIG. 3 is a detailed, schematic, magnified drawing of part of terry cloth layer 12 showing only a few loops of threads in parallel rows 22 (running across the width) with the location of the other rows being shown with straight lines. The rows running along the length are identified by the numeral 24, with most loops being omitted for the sake of clarity.
As shown in FIG. 3, terry cloth bottom layer 12 is composed of transverse rows or courses 22 and 24. Terry cloth bottom layer 12 is thus composed of continuous closed loops 23 which run at every row or course as shown in FIGS. 2 and 3 to form a pile fabric. Continuous closed loops 23 are heat bonded with a heat-activated bonding material at a bonded face 28, with loops 23 having an exterior portion 30, outside of mat 10 which could have various lengths, starting at less than 1/32″ long for relatively high absorbency and softness, and an interior portion 32 extending from bonded face 28 with a length at least as long as that of loop 23, and preferably of about 1/16″. The interior loops are longer to enhance their moisture absorption capability. The terry cloth in the preferred embodiment is a double knit material having loops 23 on both sides of bonded face 28. Its density is in the range of 320-340 grams per square meter (“GSM”). The overall content of the terry cloth is 88% biconstituent fiber (made of 78% micro-polyester and 22% polyamide nylon) and 12% polyester.
The double-sided terry cloth has been specifically knitted in the above blend of microfiber polyester and polyamide to provide for heavier and more dense loops to add higher absorbency than conventional cotton terry cloth. The foregoing terry cloth had the following test results for water absorption:


TEST RESULTS
TEST PROPERTY
SURFACE WATER ABSROPTION OF TERRY FABRICS
(ASTM D4772, after one wash)

AIR DRY	FACE	BACK
(%)	50.0%	50.0%
TUMBLE DRY LOW	FACE	BACK
(%)	50.0%	50.0%

In the event that higher absorption is required, such as for bath mats, terry cloth with loops 23 can be replaced with terry cloth with cut loops or with cut pile. The terry cloth could be quilted with stitching, and designs could be put in the terry cloth using stitching such as a diamond pattern and stripes.
Other types of fine circular knits in variations of terry cloth can also be used for different appearances. Some which can be used are 3/up and 1/down (three rows of loop terry up and one row down with no loops), 2×3/up box terry (alternating rows of two and three rows of loop terry and one row down with no loop) about ½ cm. thick, and 2/up and 1/down terry (two rows of loop terry up and one row down with no loops) composed of 88% biconstituent fiber (composed of 78% micro-polyester and 22% polyamide nylon) and 12% polyester.
The top layer of drying mat 10 according to the preferred embodiment of the invention is open-hole mesh and a jersey backing. Layer 14 is composed of an open-hole mesh front face 33 and a jersey backing 34, as shown in FIG. 2. Open-hole mesh with jersey backing top layer 14 is thus a double knit structure, meaning that it has a front face 33 and a jersey backing which front face 33 and jersey backing 34 cannot be separated. Double knit materials are made with circular knitting machines having two complete sets of needles. The thickness of the open-hole mesh is determined by the amount it is stretched on the circular loom. The circular knitting machine uses a jacquard template. Open-hole mesh with jersey backing top layer 14 is preferably 100% polyester, and its weight is about 230-245 GSM. Open-hole mesh top layer 14 is shown in enlarged form in FIG. 4. The two-sided open-hole mesh with jersey backing top layer 14 has a yarn size construction of 75D/36F×68D/24F. This weight makes open-hole mesh with jersey backing top layer 14 strong enough to keep the objects placed thereon to keep drying mat 10 from being crushed and to allow air to circulate therethrough and to enable moisture to flow therethrough as discussed below. Open-hole mesh front face 33 has a series of openings 36 with a cross dimension of 1/16″, and has knit 38 with a length between openings 36 of 1/16″ with a half-drop repeat. Openings 36 could vary from 1/16″ to ⅛″, but the side-to-side dimension of 1/16″ works most effectively. Other arrangements are also available such as an open-hole mesh with half-drop repeat with alternating ribs between the half-drop repeat.
Jersey backing 34, like front face 33, is a type of knit fabric made from 100% polyester. Jersey backing 34 is flexible, stretchy and soft, and has small, even, closed-grained stitches. Open-hole mesh with jersey backing top layer 14 is heat bonded completely to terry cloth bottom layer 12. Binding 18 is stitched along the opposing outer edges of mat 10 to assure the edges of mat 10 will have a clean professional finish. The binding material weight is preferably 111 GSM. The jersey backing 34 is a flat material which enhances the heat bonding to the adjacent fabric.
The combination of open-hole mesh with jersey backing top layer 14 and terry cloth bottom layer 12 enables air circulation for air flowing through openings 36 of open-hole mesh front face 33 into jersey backing 34 and then to the atmosphere. The purpose of this air circulation is to effect the evaporation of water from objects placed on mat 10, and to expedite the wicking of moisture into terry cloth bottom layer 12; terry cloth bottom layer 12 dries faster than other drying mats and conventional terry cloth because of the microfiber construction. This is shown schematically in FIG. 5. It can be observed that moisture M is shown schematically as flowing in the direction of arrows A_Aand being absorbed by terry bottom layer 12. Moisture from bottom layer 12 is evaporated by air circulating as shown by arrows A_Ethrough top layer 14 and loops 23 in bottom layer 12 to which top layer 14 is bonded.
The foregoing embodiment can be modified in various ways. Referring to FIG. 6, wherein original components have their original identifying numbers, a loop 42 shown in FIG. 1 can be added so that drying mat 10 could be hung on a supporting hook, handle or the like to dry. Parallel stitches 44 could be added extending across mat 10 to facilitate folding of the mat. For a mat that is about 18″ long, the stitches 44 could be 6″ apart so mat 10 could be folded in thirds. Any number of stitches could be employed depending on the dimensions of the mat and the size the mat is to be folded into.
Furthermore, an inner absorbent layer could be added, such as a jersey layer (called a “chamois”), or an additional terry cloth layer could be employed. As shown in FIG. 7, a drying mat 100 is similar to drying mat 10 but further includes a plain jersey layer or chamois 46 made of highly absorbent material such as one made out of 80% micro-polyester and 20% polyamide nylon. Even though terry cloth bottom layer 12 is very absorbent, some moisture could go through the terry cloth, and an added highly-absorbent jersey layer 46 could eliminate or greatly attenuate such a transfer of moisture. Furthermore, the circulating air through open-hole mesh with jersey backing layer top 14 would evaporate moisture in chamois 46. It should be noted that terry cloth bottom layer 12 is heat-bonded to chamois 46, and the long loops from bottom layer 12 are in contact with chamois 46.
Another variation would be to add printed latex/rubber dots of an appropriate size, such as 1 cm ½ drop repeat, for engaging the floor, countertop or whatever support surface is provided, to prevent the drying mat from slipping or skipping. It may be necessary to use a shorter exterior loop from terry cloth bottom layer 12 to use a practicable dot.
Referring to FIG. 8, a drying mat 200 is shown, which is like drying mat 10 shown in FIG. 1, having imprinted on bottom layer 12 latex/rubber dots 52 of 1 cm with ½ repeats to prevent skipping or slipping of mat 200.
Drying mats according to the invention have different opposing surfaces. They can be S-folded, as shown in FIGS. 9 and 10, when displayed for sale. An S-fold means folding a drying mat in thirds, with two of the same surfaces on opposite sides of one fold portion 48 facing each other (the two surfaces of terry cloth bottom layer 12 face each other above fold portion 48, and the two surfaces of top layer 14 face each other below fold portion 48), and two of the surfaces on the outwardly-facing surfaces of a top fold portion 50 and a bottom fold portion 52 are the opposite of each other. This enables a potential customer to see both sides of the mat without opening the mat from its folded position. This permits one to see and feel the texture and color of both sides of the mat without undoing the fold.
Drying mats according to the invention have many uses for drying, ranging from small parts, dishes, tableware, pots, pans, etc., which mats could be relatively small, such as for example 16″ by 18″, to larger objects, people and animals, in which case the drying mats would be larger. Drying mats according to the invention dry extremely well, and may well be the best drying mats for their intended function in existence. Drying mats made as described above wash very well in warm water. The drying mats discussed above are attractive in appearance and can be made without any wrinkles on either of their surfaces. They can be made inexpensively, and are ideal household items.
