DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0026] The preferred embodiments of the present invention will now be described with reference to the drawings. Identical elements in the various figures are identified with the same reference numerals.

[0027] Reference will now be made in detail to each embodiment of the present invention. Such embodiments are provided by way of explanation of the present invention, which is not intended to be limited thereto. In fact, those of ordinary skill in the art may appreciate upon reading the present specification and viewing the present drawings that various modifications and variations can be made thereto.

[0028] Referring now to FIG. 1, there is a diagram demonstrating a phase change material utilized in an embodiment of the present invention. The cooling chemistry or phase change material comprises a microencapsulated phase change material (PCM) in any form such as but not limited to a slurry, wet cake, and/or dry powder or combinations thereof. The microencapsulated PCM may comprise at least one of the following components and/or properties: organic center types of PCM, paraffin, fatty acids and/or polyglycols, inorganic or bio-based centers, formaldehyde, acrylic, or any hybrid shell. The PCM may further be inclusive of any available or customized melting point (e.g. 24 C., 28 C., 32 C., 37 C., 43 C., 58 C. and 65 C.).

[0029] The application of the cooling chemistry can applied onto any type of textile substrate. The add-on of the cooling chemistry can be from 0.01 oz/sq. yd. to 100 oz/sq. yd. dry weight. The applied solution can be from 1% to 100% cooling chemistry. Inactives comprising the cooling chemistry may comprise water, hydrocarbons or other materials capable of having the PCM suspended therein. The cooling chemistry may be applied evenly over a particular surface or may comprise various patterns or configurations on the textile material.

[0030] Referring now to FIG. 2, there is a diagram showing a screen printing methodology of the present invention such as a rotary, flat or hand printing, or automatic screen printing press. The process of applying the cooling chemistry to the textile through a screen involves a blade that squeezes the cooling technology through openings in the screen onto the fabric or textile. The openings can be continuous over the confines of the screen or could create a design and/or pattern. The mesh used to apply the cooling chemistry includes any available size mesh from 40 to a Galvano screen. In some embodiments, multiple coatings may be required to fully complete the application of the cooling chemistry to the textile.

[0031] Referring now to FIG. 3, there is a knife over roller coating methodology. The cooling chemistry is being applied to the textile which then passes through a gap between a knife and a support roller. As the coated cooling chemistry and the substrate pass through, the excess is scraped off leaving behind the cooling chemistry to dry on the textile.

[0032] Referring now to FIG. 4, there is a dip coating methodology illustrated. In this process, the textile is dipped into a bath of the cooling chemistry coating, passed through squeeze rollers to control the cooling chemistry coating thickness or add on, then carried through a series of ovens (either horizontally or vertically) for drying and curing.

[0033] Referring now to FIG. 5, there is an air knife coating methodology. This is a relatively simple process where the cooling chemistry coating is applied to the substrate and the excess is blown off by a powerful jet from the air knife with the remaining cooling chemistry being allowed to dry.

[0034] Other coating methodologies may include but are not limited to gravure coating, reverse roll coating, metering rod coating, and slot die coating. The gravure coating process relies on an engraved roller running in a coating bath, which fills the engraved dots or lines of the roller with the cooling chemistry coating material. The excess coating on the roller is wiped off by the Doctor Blade and the coating is then deposited onto the substrate as it passes between the Engraved roller and a Pressure Roller. In reverse roll coating, the cooling chemistry coating material is measured onto the applicator roller by precision setting of the gap between the upper metering roller and the application roller below it. The coating is wiped off the application roller by the substrate as it passes around the support roller at the bottom. In metering rod coating, an excess of the cooling chemistry coating is deposited onto the substrate as it passes over the bath roller. The wire-wound metering rod, sometimes known as a Meyer Rod, allows the desired quantity of the coating to remain on the substrate. The quantity is determined by the diameter of the wire used on the rod. In the slot die process, the cooling chemistry coating is squeezed out by gravity or under pressure through a slot and onto the substrate.

[0035] Referring now to FIG. 6, there is a dyeing methodology shown. The technique or process used in pad-batch dyeing starts with saturating first the prepared fabric with pre-mixed cooling chemistry. Then it is passed through rollers. The rollers, or padders, effectively forces the cooling chemistry into the fabric. In the process, excess cooling chemistry is also removed.

[0036] FIG. 7 illustrates a prior art pillow which exhibits breathability issues. Here, the pillow is formed of a first face and a second face. The first face is directly affixed to the second face via stitching. As a result, there is limited, if any, exchange of air from inside of the pillow to the outside of the pillow. The result is a pillow that does not provide adequate temperature regulation to a user and is uncomfortable to use.

[0037] FIG. 8 illustrates a pillow of the present invention where the gussets allow for breathability and enhanced performance of the pillow. Here, the top and bottom fabrics are a textile treated with cooling chemistry. The side of the top and bottom fabrics comprising the cooling chemistry could be inside or outside (inner surface or outer surface) of the pillow. The cooling chemistry may be applied by any of the above described methodologies or another methodology not explicitly described herein.

[0038] The pillow, as shown in FIG. 8, further comprises an untreated textile gusset on all (four) sides of the pillow. That is, a gusset that does not contain the cooling chemistry treatment as described herein. In some embodiments, the gusset may be on less than all sides of the pillow. In other embodiments, the pillow has more or less than four sides with the gusset being on all sides or less than all sides of the pillow.

[0039] This gusset can have a height size from 0.01 in to 10 in or more depending on the pillow size and the desired amount of air exchange between an interior of the pillow and an environment of the pillow. Preferably, as stated above, the gusset is disposed around an entire periphery of the pillow. With most textiles that may be used in implementations of the present invention, the cooling chemistry creates an unbreathable layering or coating, preventing the pillow the proper breathability. Thus, the gusset construction described herein allows the proper breathability on all sides of the pillow. The gusset can be made of any type of substrate, in any color or pattern. The pillows can be filled with any type of fill. The pillow is then closed shut and is ready for use.

[0040] Further embodiments of the present invention may include but are not limited to pillow covers or pillow protectors, mattress pads and protectors, comforters, duvet covers, blankets, pet beds, furniture covers, etc.

[0041] A pillow cover is typically any cover used to protect any type and size of bed sleeping pillow, body pillows and travel pillows. In accordance with the present invention, the pillow covers comprise a top and a bottom fabric comprising a textile treated with the cooling chemistry. The treated side of the textile with the cooling chemistry may be an inner surface, an outer surface, or a combination thereof of the pillow cover or protector. Further, the pillow protector preferably has an untreated textile gusset on all sides of the pillow cover or protector. This gusset have a height from 0.01 in to 10 in or more.

[0042] Mattress pads, as shown in FIG. 9, a covering that goes under a sheet on a bed to protect the mattress. It can be single or multi layers. The top layer has the cooling chemistry application on either or both sides of the textile. It can be quilted or not. Can have a skirt that goes around the platform of the mattress or anchor bands that holds it in place on four corners.

[0043] A comforter is a thick, quilted, fluffy blanket that is used to keep you warm. It is usually filled with synthetic fiber filler which is quilted or stitched to secure the filling and keep it evenly distributed. The cooling chemistry can be used on the back side of the comforter.

[0044] A duvet cover comprises fabrics sewn together creating a protector or cover for a comforter or duvet with any style of closure.

[0045] A blanket can be a single layer of a textile or a triple layer, etc. On a single layer, the cooling chemistry is applied to one side of the textile. The triple layer blanket consists of a face and back textile with a natural or synthetic inner layer. All three layers are quilted together. In this case, the cooling chemistry can be applied to one side or both sides of the blanket.

[0046] A pet bed is a bed designed for a pet. It can be single or multi layered using any type of substrate or design. The layer that is in contact with the pet will have the cooling chemistry applied to either or both sides of the substrate.

[0047] Furniture protectors comprise a single or multi-layer cover to protect any style/type of furniture. The top layer of the protector will have the cooling chemistry application on both or either side.

[0048] Although this invention has been described with a certain degree of particularity, it is to be understood that the present disclosure has been made only by way of illustration and that numerous changes in the details of construction and arrangement of parts may be resorted to without departing from the spirit and the scope of the invention.
