A disadvantage of known breathable fabrics is the fact that if an article made from the breathable fabric is placed between a part of a human or animal body and a surface, the ventilation will be impeded. This disadvantage is particularly acute when the surface is hard and / or unperforated and / or when the article is subjected to additional external pressure, for example from the weight of a human or animal, or from a surface that leans heavily on the article.

It is an object of the present invention to go at least in part towards resolving the above disadvantages, or to at least provide an alternative to existing products.

[0006]

[Means for Solving the Problems]

According to a first aspect of the present invention, a first major surface and a second major surface are addressed to each of a first side and a second side of an article, and in use, a human or animal of the first side is used. An article comprising a sheet adapted to be disposed at least intermittently between a portion and a surface on a second side, the sheet comprising a substantially impermeable material having through holes therethrough. In, the sheet, from a part of a human or animal, from the surface,
Or a plurality of spacer members protruding from at least one of the major surfaces of the sheet between the through holes in the sheet to provide a certain distance from both, so that the surface and the portion of the person or animal are used in use. An article is provided, characterized in that the article has a breathability between the two and reduces discomfort to humans or animals. Such articles are not always, but always in the form of a sheet, i.e. do not include additional component parts that are not sheets.

[0007] According to a second aspect of the present invention, there is provided, but not limited to, a breathable fabric for special use in manufacturing an article according to the first aspect of the present invention, the fabric comprising: A breathable fabric comprising a sheet having a first major surface and a second major surface and formed of a substantially impermeable material having through holes therethrough; A plurality of spacers projecting from at least one of the major surfaces of the sheet between through holes in the sheet to space the sheet from a portion of a human or animal, from a surface, or from opposite major surfaces of the sheet. It consists of a breathable cloth to which the member is attached. The fabric is generally cut into a desired shape and then any desired additional component parts of the article are attached or formed to produce the final breathable article.

In one specific embodiment, a spacer member protrudes from at least a second major surface of the sheet in order to space the sheet from the surface (optionally, a second member of the sheet). From the main face only).

[0009] In a further embodiment, a spacer member may protrude from at least a first major surface of the sheet in order to space the cloth sheet from a person or animal (optionally a first sheet of the sheet). Only from the main face).

In a preferred embodiment of the present invention, the fabric sheet further comprises a hollow depression or chamber formed in the first major surface of the sheet in the region of each through-hole. WO-A91 / 1295
8, according to such an arrangement, air can pass from the first side of the article to the second side and accumulate in the cavity or chamber under increased vapor pressure,
Exit to the second major surface of the article.

Further, one recess or chamber may be in communication with two or more through holes. The cross-sectional dimensions of the recess or chamber may range, for example, from about 0.4 mm to about 50 mm, and more typically from about 0.4 mm to about 30 mm. The sheet densities or surface densities of the chambers may be up to about 500,000 m ^-2 , for example, from about 200 to about 500,000 m ^-2 . The surface density of the depressions or chambers can be chosen by a person skilled in the art according to the required breathability properties. For example, surface densities of small depressions or chambers of greater than 100,000 per m ² typically communicate with through-holes including cross-sectional dimensions that may be less than about 0.1 mm, for example, as small as about 0.01 mm, It may be useful for specialized articles such as medical or veterinary bandages or other dressings.

[0012] The thickness of the sheet can be selected to match the desired use of the article.
For example, this thickness may be between 0.5 and 100 mm, for example less than about 50 mm, in particular 1
To 30 mm, and in the most special cases from about 3 to about 15 mm.

The through holes may be of any convenient or useful shape, such as, for example, circular, slit-like or elliptical, and when viewed along their length, may be up to about 5 mm (eg, about 0.5 mm). Preferably, it has a cross-sectional dimension of from about 1 mm to about 5 mm). This through-hole preferably has a size, for example, pierced by a pin having a diameter of about 0.2 to about 2 mm. Preferably, the center between adjacent through-holes is separated by a maximum of about 100 mm, for example, a maximum of about 30 mm. For example, the through-holes may be arranged in a repeating diamond pattern or another repeating pattern over the entire surface of the sheet.

As used herein, the expression “cloth” includes a cloth portion, and the expression “sheet” includes a sheet portion.

For example, the article conforms to the shape of a human or animal or surface in use, since the spacer member protrudes from the sheet by a substantially constant distance over at least a majority of the major surface of the sheet. Alternatively, the spacer member changes in length as one moves away from the sheet, for example to adapt to a surface or a particular contour of a human or animal.
This spacer member may be discontinuous or continuous. The spacer member preferably comprises a rib extending from the sheet or a separate or point-like projection. For example, the spacer member may be adhered to the sheet or may be integral with the sheet.

[0016] The substantially impermeable sheet may be a single sheet or a laminate, and is preferably an elastomeric system. The element can be foamed or non-foamed. In the case of a foamed product, the foamed structure may be closed cells or open cells. Open cells are usually inherently permeable to some degree, but the perforations significantly improve the permeability, so that the foam is referred to in the present specification as "substantially inefficient." It is understood to be "osmotic". Suitable elastomeric materials include, for example, synthetic and natural rubbers such as neoprene rubber,
And / or all types of synthetic polymers. In the case of a laminate, various materials may be used for other lamina as needed.

The sheet is preferably a sheet of the above-mentioned well-known stomatex type. Most preferably, a dome-shaped protrusion is arranged on the second major surface of the seat in the area of each through-hole corresponding to the hollow chamber of the first major surface of the seat. In use, the pressure change occurs in the chamber, causing the dome projection to bend, and this bend removes humid air from human skin in contact with the first major surface of the seat. Is encouraged.

In such a preferred embodiment, the spacer member is adapted to keep the dome at a fixed distance from the surface, so that the bending action is not impeded during normal use.

The spacer member preferably projects from the second major surface of the sheet by at least a substantial amount at least a majority of the second major surface of the sheet so that, in use, the article conforms to the shape of the surface. Match. The spacer member has such a degree that the through-holes of the sheet remain open to the second side of the article during normal use, that is, the second side of the article does not easily deform when the surface is pressed. Preferably have sufficient elasticity.

Preferably, the spacer member comprises a network of ribs extending over substantially all of at least one side of the article or fabric, such that the ribs allow each dome-shaped portion of the second major surface of the sheet. A side wall of the protrusion is provided. Optionally, this allows the space formed above the dome-shaped protrusion to extend between each rib and be fixed (eg, tightly fastened) to the rib. It can be covered with a cover member.

In a particularly preferred arrangement, the breathable seat cover member may be a water-absorbent garment or another fabric, for example a hydrophilic fiber such as highly wicking microfibers, especially polyester. Such a cover member exerts a high suction effect of absorbing moisture passing through the through hole from the first major surface to the second major surface of the sheet.
In this way, the surface against which the article is pressed can be kept as dry as possible. Alternatively, for example, the breathable sheet cover member may be a waterproof but moisture permeable member. Further, such a waterproof but moisture-permeable member can be used together with a water-absorbing cloth. For example, an apparently water-absorbing cloth which exhibits waterproofness may be used. If desired, such a composite may be a laminate in which the various layers are adhered in a conventional manner.

The surface on which the article of the present invention can rest may be difficult to bend or bend easily, may be perforated or not perforated, and may be permeable or non-permeable. The article of the present invention can also be wrapped around a portion of a human or animal body (eg, a limb), in which case the "surface" is the article wrapped around the portion of the article that is in contact with the human or animal body Ie, an article (eg, a bandage) is wrapped on itself.

The articles of the present invention may be, for example, semi-permanent or removably attached surface finishes, cushions for wearing or positioning on any surface or between a person or animal and any surface It can take the form of materials and patches: (a) all types of garments, such as water sports garments, and parts of such garments (eg seated trousers); (b) cloth parts of wheelchairs (E.g. seats, backrests and armrests); (c) car chair upholstery, office chair upholstery, home chair upholstery, boat chair upholstery, transportation chair upholstery. (D) all types of hats; (e) boots and shoes, for all types of chairs, such as (upholstery for bus, train and airplane chairs); Inside (F) a helmet patch, the surface in this case is the helmet inner surface; and (g) a protective clothing, in this case. The surface is the inner surface of the protective gear; (h) the patch cloth for bulletproof vests, the surface in this case is the inner surface of bulletproof vests; (J) Underlay blanket for bedding, the surface in this case is the upper surface of a mattress or the like; (k) Upholstery cover, the surface in this case is the surface of the upholstery (L) a garment patch, where the surface is the inner surface of the garment; (m) an orthopedic cast patch, the surface being the orthopedic cast inner surface; (n) Orthopedic support or hard anchor pad , The surface of the case is the inside surface of the orthopedic support or rigid fixture; the portion of the case where, as well as (o) otherwise, parts particularly subject to compressive forces in use.

The articles of the present invention may also take the form of medical or veterinary bandages, for example,
overlying members (optionally with or without the use of a contact adhesive between the bandage and the skin of the person or animal), or over the bandage around a body part (eg, limb) It is fixed to the body by wrapping a bandage.

The basic principle underlying the preferred mode of operation of the through holes in the sheet is WO-A 9
1/12958. This basic principle applies when the corresponding sheet is used together with the spacer member according to the invention. Essentially, as the sweat evaporates from the surface of the human skin, the vapor pressure (density) in the hollow chamber of the sheet increases. Human body movement,
For example, when walking using the article of the present invention as an insole, compression of the sheet and subsequent deformation of the room or dome occurs. This will actively push steam from the chamber through the through hole to the second side of the article. If the temperature is lower than the wearer's body, then the vapor will tend to condense.

When the spacer member is used with a breathable hydrophilic fiber, the water-absorbent sheet cover member surrounds the space above the dome-shaped protrusion on the second major surface of the seat, thereby condensing sweat. Is absorbed into the fibers of the water-absorbing cover member. Once condensed, sweat cannot return through the through hole. Even if the sweat remains vapor in the space above the dome-shaped protrusion, the sweat will be a positive heat and diffusion gradient from the first major surface of the sheet to the second major surface, so that the sweat will be the first major surface of the sheet. Will not return to the main room.

[0027] The through-hole and the chamber following it allow the natural biological function of the user's skin to remain substantially unhindered for a long time, while controlling the user's body temperature (but It is preferred to have sufficient dimensions and spacing (not to be excessive).

The elements of the article and fabric are not only non-toxic, non-irritating and comfortable to wear (in the sense of being light, soft and comfortable), but also of the entire body of the user. It should also be resistant to the effects and degradation from natural excretions (eg, gases such as sweat, blood, tissue fluids, urine, juice and carbon dioxide).

The article substantially protects the wearer from cold or other external hazards (eg, water, chemicals, bacteria, air, etc.) while increasing air exchange efficiency as soon as the wearer's activity is increased. It is preferred that the through-holes be opened because this can increase the flexibility of the article and / or the temperature and pressure inside the sheet chamber. In such articles, the through-holes also preferably vary with a relatively small number of other types of through-holes according to the invention and / or other (eg, conventional) through-holes. In one particular configuration, the through hole is opened when the water vapor pressure of the chamber reaches the saturated vapor pressure.

Specific elastomeric materials, specific lamina thickness, specific dimensions of chambers and through-holes, various aggregations of through-holes across the sheet surface and / or through-holes throughout the sheet surface By choosing various types of arrangements, the properties of the article can be adjusted to suit the intended use. In addition, through careful selection of materials and shapes, the article may be "breathable" to accommodate external conditions and / or changes in the biological function of the user, and to some extent this Such articles can self-adjust their "breathability" so that the environment can be automatically controlled within a preset temperature range, very close to the wearer's skin.

[0031] Fabrics and articles made from such sheets can be manufactured by conventional methods. Thus, for example, by pressing, for example thermoforming under pressure, or vacuum forming from a foamed or non-foamed elastomeric sheet, the required chambers, dome and spacer members are obtained, and the sheet is perforated with pins. By doing so, a through hole can be obtained. The perforation of the sheet may be performed at the same time as the press forming or the vacuum forming, or at a different time from the press forming or the vacuum forming.

Alternatively, a spacer member can be laminated to the rest of the sheet.
This is suitable when the elasticity of the spacer member must be different from the elasticity of the portion of the article where the through hole is formed. In such a method, the required chamber and dome can be obtained by pressing or vacuum forming the first sheet portion of the first elastomeric material, and the perforation can be obtained by perforating the sheet with a pin. . As mentioned above, the through-holes in the sheet can be made simultaneously with the press or vacuum forming, or at a different time from the press or vacuum forming. A second sheet portion of the second elastomeric material (typically separate from the first elastomeric material) is passed through a relatively large hole large enough to comfortably receive a dome protruding from the first sheet portion. I can do it. The two sheet parts can be laminated together in such an arrangement, so that the spacer member according to the invention is obtained from the second sheet part.

If an additional transmissive layer is to be laminated or glued to the fabric, this lamination or gluing may be, for example, to confine the space above the dome to the second major surface of the sheet over the entire spacer member. It can be performed in a conventional manner using known materials and methods.

After the initial shaping of the fabric, the article of the present invention, if necessary, with or without additional elements to the perforated sheet as described above, can be cut, pressed and / or pressed, for example. Or, formed from the fabric by any suitable means, such as stamping, the desired type of article can be combined with any conventional optional additional elements to form the final article. For many surface finishes, cushioning or patch fabric articles, no or little processing is required after the fabric has been cut, pressed or stamped and shaped. Such matters are well known to those skilled in the art because of their simple similarities to the corresponding handling and processing of known fabrics.

The present invention provides a simple, inexpensive, easy to wear or position between a person or animal and a jacket.
At least one way toward providing a comfortable, thermally insulable and washable yet effective facing, cushioning or patching system has been undertaken, thereby explaining the aforementioned problems of introduction.

To facilitate understanding of the invention and to explain how the invention can be effectively carried out, reference will now be made, with reference to the drawings, without limitation, by way of example only,
An embodiment will be described below.

[0037]

BEST MODE FOR CARRYING OUT THE INVENTION

In the drawing, the same parts are given the same names and show a fabric sheet 1 from which a breathable article can be produced. The fabric sheet has a first major surface 2 and a second major surface 3 that define a first side and a second side of the fabric. These first and second major surfaces of the fabric sheet 1 are addressed to corresponding first and second sides of the finished article. In use, the article made from the cloth is close to the human or animal body 4, the human / animal is on the first side 2 of the cloth and the surface 5 is close to the second side 3 of the cloth. As such, the article is placed between the human / animal and the surface 5.

The cloth sheet 1 is a sheet made of a foamed elastomer neoprene having a through hole 6 of a size formed by a small diameter pin. A circular hollow chamber 7 is formed in the first major surface 2 of the sheet, one chamber being in the region of each through-hole 6, the through-hole coinciding with the tip of each chamber. The second major surface 3 of the seat has a dome-shaped projection 8, one dome-shaped projection 8 being in the area of each through-hole 6, the through-hole also coinciding with the tip of each dome.

With this arrangement, air passing from the first side of the fabric to the second side is compressed and accumulates in the chamber 7 before passing through the through holes 6 to the second side of the fabric. I do. In this process, the elastomeric sheet can deflect both under the effects of pressure changes and as a result of mechanical bending. Such flexible movement contributes to the positive pumping effect, which effectively pumps moist air from the first side of the fabric to the second side.

A plurality of spacer members in the form of ribs 9 projecting from the second major surface 3 of the sheet between the through holes 6 and serving to separate articles made of cloth from the surface 5 are provided. Even if the article 1 is about to be crushed against the surface 5 by the weight of a human, the flexing action can be maintained without interruption.

If desired, the elastomeric material may be coated with a thin layer (not shown) of a material that is compatible with the skin, the material comprising natural fabrics of cotton, nylon or mixtures thereof and / or Or a synthetic cloth is suitable. Although the ribs 9 are shown integrally with the sheet, they may alternatively be laminated to the sheet generally as described above.

As shown in particular in FIG. 3, the sheet 1 is provided with a water-absorbent cloth layer 10 (for example, a hydrophilic microfiber fabric) bonded to a rib 9 so as to surround a space above the dome-shaped protrusion 8. Each space may have a dome-shaped protrusion 8, a rib 9, and a water-absorbent cloth layer 1.
It is surrounded by 0. As described above, the water-absorbing cloth layer may be replaced with a waterproof but vapor-permeable membrane, or may be added, as needed, for example, to provide waterproofing.

It is preferred that the water-absorbent fabric layer 10 exhibit a high wicking effect and absorb any liquid water that comes into contact with this layer. This layer retains moisture inside the fabric and suppresses accumulation of moisture on the surface 5. The fabric can be easily replaced or periodically cleaned, eliminating accumulated moisture. If this is hygienic and acceptable, the fabric may be allowed to dry overnight for reuse without washing.

After the fabric is formed, various articles according to the invention are made from the fabric, for example, by any suitable method of cutting, pressing and / or punching. Examples of such articles have been described above and will not be repeated here. If the article includes a sheet element and another element conventionally used with the sheet, the final article is formed by incorporating these elements in a generally known manner. However, in many cases, after the fabric has been cut, pressed or stamped and formed, a simple facing, cushioning or patching article requires little or no processing. The foregoing is well known to those skilled in the art, simply by analogy with the corresponding handling and processing of known fabrics.

The illustrated fabric is suitably manufactured by conventional press molding or vacuum forming of a foamed neoprene sheet to form a chamber 7, a dome 8 and a spacer member 9. If necessary, the water-absorbent cloth layer 10 can be bonded to the spacer member 9 by a conventional method using a conventional contact adhesive. The through hole 6 is preferably formed by a pin.
Or you may form simultaneously by applying a press molding process.

It can be seen that the cloth shown retains the advantages of breathability and the positive pumping effect of the dome 8 and chamber 7 even when compressed by human weight. Such important advantages have never been exploited for use as a patch within a relatively neat outer cover, severely limiting the application of modern breathable fabrics.

The above description has broadly described the present invention without being limited to the specifically illustrated embodiments. Variations and modifications which are obvious to those skilled in the art are included in the scope of the present application and later patents.
