Abstract
Disclosed is a wearable thermal protection and perspiration management apparatus that includes a two-ply composite main body and an inner layer of elastic material. The two-ply main body includes an outer layer made of moisture absorbent material and an interior layer made of moisture wicking material this is arranged in contact with the outer layer of moisture absorbent material. The interior layer provides a moisture barrier which is adapted for preventing captured moisture from contacting a wearer's body. The inner layer of elastic material is adapted and configured to secure the two-ply composite main body in contact with the wearer's body. Preferably, the two-ply composite main body has a Thermal Protective Performance rating of greater than 35 cal/cm.sup.2.

Description
BRIEF DESCRIPTION OF THE SEVERAL VIEWS OF THE DRAWING
(1) While the specification concludes with claims particularly pointing out and distinctly claiming the subject matter of the invention, it is believed the present disclosure will be better understood from the following description taken in conjunction with the accompanying drawings, wherein:
(2)
(3)
(4)
(5)
(6) These and other aspects of the subject disclosure will become more readily apparent to those having ordinary skill in the art from the following detailed description of one or more embodiments of this disclosure taken in conjunction with the drawings.
DETAILED DESCRIPTION OF THE INVENTION
(7) Embodiments of this disclosure are now described more fully with reference to the accompanying drawings, in which illustrated embodiments are shown. This disclosure is not limited in any way to the illustrated embodiments as the description below is merely provides exemplary embodiments in various forms, as appreciated by one skilled in the art. Therefore, it is to be understood that any structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a basis for the claims and as a representative for teaching one skilled in the art to variously employ the embodiments disclosed herein. Furthermore, the terms and phrases used herein are not intended to be limiting but rather to provide an understandable description of the embodiments herein.
(8) Referring now more particularly to the accompanying drawings which show several of the preferred embodiments of the invention,

(13) Lastly,
(14)
(15)
(16)
(17) Item 31 represents the elastic layer which is comprised of a 4-way stretch material such as Lycra, Spandex, Luan, or similar This material allows the apparatus to adjust to fit multiple parts of the body and various sized users and to conform the apparatus to the shape of the wearer. This elastic property will be the primary mechanism that allows the device to remain positioned on the body of the wearer by means of the compressive properties of the elastic.
(18) Item 32 represents the moisture absorbency layer of the apparatus that is utilized as the mechanism to manage perspiration. This layer contains multiple materials that are woven together as a single element comprised of Cotton, Bamboo, Polyester and other fibrous materials designed to absorb and transfer perspiration away from the surface. The surface being defined as the area that is in direct contact with the air and the point of contact with which the wearer would use the apparatus to remove sweat from other parts of the body (e.g. the forehead). This layer is also designed to distribute perspiration from the surface down the layer in order to maximize absorbency while allowing the surface to absorb more perspiration.
(19) Item 33 serves as an additional wicking layer that transports the perspiration captured in layer 32 and distributes it laterally to increase absorption capacity. This layer additionally provides a barrier between captured perspiration and the wearer's skin inside the apparatus.
(20) In order to utilize the apparatuses, garments or articles of the present disclosure in applications wherein a user such as a chef, firemen or racecar driver may potentially be exposed to a heat source or flame, they must be certified in accordance with the National Fire Protection Association standards.
(21) Whether its culinary service garments or firefighter turnout gear, boots or gloves, rigorous tests are performed to ensure the product can withstand the thermal conditions associated with the job. National Fire Protection Association 1971 certification requires the greatest number of tests, across the widest range of protections (heat, flame, liquids, viral penetration, and durability tests).
(22) Amongst the most well-known and discussed test results are Thermal Protective Performance (TPP) and Total Heat Loss (THL). The presently disclosed apparatuses, devices, garments have been tested to determine a TPP rating (Thermal Protection Performance). TPP is a calculated value that manufacturers use to rate the exposure to heat, energy and the approximate time before skin is subject to second degree burns (when skin starts to blister). Typically, the only way to increase the TPP value is by adding layers.
(23) A two-ply fabric cut from forearm sweat sleeve that was constructed in accordance with the present disclosure was tested to determine its TPP rating. One layer was a quilted fabric and the other a knit fabric. The test was conducted with the quilted layer closest to the heat source. The results of the test were as follows:
(24) TABLE-US-00001 Burn # Time to Burn (sec) TPP Value (cal/cm.sup.2) 1 17.681 35.501 2 19.566 38.891 3 20.406 40.560 4 17.756 35.292 5 20.064 39.880 Average 19.094 38.027
(25) TABLE-US-00002 Calibration Parameters Calibrated HF (kW/m.sup.2) 83.218 Calibrated HF (cal/sec .Math. cm.sup.2) 1.988
(26) A total of six samples were submitted for testing. The sixth sample was separated and the two component layers were tested individually. This was done to provide an idea of how each individual layer would perform under similar conditions as the combined fabrics were tested.
(27) TABLE-US-00003 Burn # Time to Burn (sec) TPP Value (cal/cm.sup.2) Quilt Layer only 10.346 20.563 Knit Layer Only 4.965 9.868
(28) As shown above, the sample article exhibited a TPP rating of 38 cal/cm.sup.2 on average and the results ranged between 35 and 40 cal/cm.sup.2. Such a TPP rating will protect the wearer from suffering second degree burn for 17 seconds and is considered acceptable for articles or garments such as firefighter turnout gear. As a result of the materials performance, the articles, apparatuses and garments of the present disclosure provide sufficient thermal protection such that they can be utilized in applications that have the potential for exposure to heat, such as culinary applications.
(29) The information provided and invention as presented have been described to the inventor's preferred incarnations, it will be understood by those skilled in the art that various changes may be made and elements or materials substituted or modified without departing from the true intent and scope of the invention.
