Description

TECHNICAL FIELD

The present disclosure generally relates to cooling fabrics, and more particularly to three-layer circular knitted jacquard fabrics made from different yarns to provide cooling to the body of a user, or a portion thereof, resting on the fabrics. Articles of bedding made from such fabrics and methods of use are included.

BACKGROUND

Sleep is critical for people to feel and perform their best, in every aspect of their lives. Sleep is an essential path to better health and reaching personal goals. Indeed, sleep affects everything from the ability to commit new information to memory to weight gain. It is therefore essential for people to use bedding that is personalized to fit both their individual sleep preference and body type, in order to achieve comfortable, restful sleep.

Selecting the appropriate type of bedding is an important aspect in achieving proper sleep. For example, selecting a pillow, mattress, mattress cover, mattress topper, etc. that feels cool as it absorbs heat from the user's body can greatly affect how comfortable the user is when they sleep. The cool feel of such bedding may be controlled by selecting bedding made from a fabric or other material that provides a desired level of coolness. Cooling fabrics or materials may be formed of materials, such as, for example, various foams or gels. However, conventional cooling fabrics used in bedding are known to feel coarse or otherwise uncomfortable to the touch, which can prevent restful sleep. This disclosure describes an improvement over these prior art technologies.

The second layer is positioned between the first layer and the third layer such that the second layer provides loft between the first layer and the third layer. In some embodiments, the layers can be made with the same materials. For example, the second layer may be made from a material, such as, for example, a polyester material and the third layer can also be made from the same material as the second layer. In some embodiments, a top layer, such as, for example, the first layer can be coated with a phase change material and a bottom layer, such as, for example, the third layer can be coated with a phase change material. It is envisioned that the first layer and/or the third layer can be soaked with a phase change material and/or can be infused with a phase change material.

The percentages are calculated based on total volume.

In one embodiment, in accordance with the principles of the present disclosure, the first material comprises ultra-high weight molecular polyethylene; the second material comprises polyester, moisture wicking polyester, and viscose with a phase change material, and the third layer comprises polyester. It is envisioned that the viscose can be soaked with a phase change material and/or can be infused with a phase change material. In some embodiments, the moisture wicking polyester is a high-performance functional polyester fiber. Its cross section differs from regular polyester fiber. The moisture wicking polyester fiber is “cross” shaped with multiple ditches around it. The ditches formed by the specific cross section create channels and when placed next to each other, which speeds up the moisture transport and diffusion process. The wicking channels within the fiber and between fiber yarns quickly move sweat to the surface of the fabric where it is evaporated. Such cross section also creates a large surface area which picks up moisture and carries it away from the body, spreading it out, to evaporate easily on the outside of the fabric through capillary action over a wider surface area. Moisture wicking polyester fiber can also be combined with a moisture wicking finish on fabric surface or a unique fabric construction in order to achieve balanced temperature regulation to prevent overheating.

In one embodiment, in accordance with the principles of the present disclosure, the viscose is a yarn that is coated with the second phase change material. In one embodiment, in accordance with the principles of the present disclosure, the yarn of the first layer is made from the ultra-high weight molecular polyethylene and the phase change material is embedded within the yarn of the first layer.

In one embodiment, in accordance with the principles of the present disclosure, the first layer and the third layer form a substrate that surrounds the second layer, with all three layers then calculated by total volume as comprising 33% ultra-high weight molecular polyethylene, and 50% polyester, including moisture-wicking polyester, and 17% viscose inclusive of the phase change material; with the second material included in this calculation and comprising of 50% of the viscose with phase change material, 7% of the moisture-wicking polyester, and 43% standard polyester, by the volume calculation for this layer.

In the embodiments discussed herein wherein the fabric includes ultra-high weight molecular polyethylene and a filler material, such as moisture-wicking polyester and/or a viscose fiber with phase change material, the phase change material is used to provide a long-lasting cooling effect. Once heat is transferred from the user's body to the fabric, molecules of the phase change material meet the ultra-high weight molecular polyethylene, which acts as a heat source. This heat exchange between the user's body and the molecules of the phase change material causes a core of the phase change material to change from a solid to a liquid to create a cooling sensation. When the heat source is removed, such as, for example, by removing the user's body from the fabric, the core of the phase change material releases stored latent heat and solidifies. This resets the molecule's cooling capacity. As such, the phase change material acts as a storing mechanism for body heat, thereby facilitating the ultra-high weight molecular polyethylene for continuous heat exchange. In some embodiments, the phase change material provides for absorption of surplus body heat, provides an insulation effect caused by heat emission of the phase change material into the fabric, and provides a thermo-regulating effect that keeps the micro climate temperature nearly constant. It is envisioned that any of the layers and/or yarns can be soaked with a phase change material and/or can be infused with a phase change material.

In one embodiment, in accordance with the principles of the present disclosure, an article of bedding is provided that includes first and second panels, inner surfaces of the panels defining a cavity; and a fill material disposed in the cavity, wherein at least one of the panels is made from one or more of the fabrics discussed herein.

DETAILED DESCRIPTION

The exemplary embodiments of fabrics are discussed in terms of three-layer circular knitted jacquard fabrics that provide a cooling effect when used in bedding, such as, for example, pillows, mattresses, mattress covers, mattress toppers, blankets, etc. The present disclosure may be understood more readily by reference to the following detailed description of the disclosure. It is to be understood that this disclosure is not limited to the specific devices, methods, conditions or parameters described and/or shown herein, and that the terminology used herein is for the purpose of describing particular embodiments by way of example only and is not intended to be limiting of the claimed disclosure.

Also, as used in the specification and including the appended claims, the singular forms “a,” “an,” and “the” include the plural, and reference to a particular numerical value includes at least that particular value, unless the context clearly dictates otherwise. Ranges may be expressed herein as from “about” or “approximately” one particular value and/or to “about” or “approximately” another particular value. When such a range is expressed, another embodiment includes from the one particular value and/or to the other particular value. Similarly, when values are expressed as approximations, by use of the antecedent “about,” it will be understood that the particular value forms another embodiment. It is also understood that all spatial references, such as, for example, horizontal, vertical, top, upper, lower, bottom, left and right, are for illustrative purposes only and can be varied within the scope of the disclosure. For example, the references “upper” and “lower” are relative and used only in the context to the other, and are not necessarily “superior” and “inferior”.

The following discussion includes a description of three-layer circular knitted jacquard fabric 10 that provides a cooling effect when used in bedding. Alternate embodiments are also disclosed. Reference will now be made in detail to the exemplary embodiments of the present disclosure.

The components of fabric 10 can be fabricated from materials including polymers and/or composites, depending on the particular application. For example, fabric 10 can be fabricated from materials such as fabrics or textiles, yarns, fibers, paper or cardboard, cellulosic-based materials, biodegradable materials, plastics and other polymers, semi-rigid and rigid materials. Fabric 10 may also be fabricated from a heterogeneous material such as a combination of two or more of the above-described materials. Fabric 10 and/or components thereof can be knitted, woven, extruded, molded, injection molded, cast, pressed and/or machined.

Fabric 10 is a three-layer circular knitted jacquard fabric, as discussed herein. In some embodiments, the circular knitting process includes circularly knitting yarn or other material into a fabric, such as, for example, fabric 10. Circular knitting may include organizing knitting needles into a circular knitting bed. The knitting needles produce a circular fabric that is in a tubular form through the center of the cylinder. The circular fabric is then cut to produce fabric 10 such that fabric 10 has a square or rectangular shape. This allows fabric 10 to be formed from a single, continuous piece of performance fabric that is produced using circular knitting. As such, fabric 10 may extend from a first side surface to a second side surface without including any seams between the first side surface and the second side surface. Fabric 10 may also extend from an upper surface to a bottom surface without including any seams between the upper surface and the bottom surface.

In some embodiments, fabric 10 undergoes finishing processes, such as, for example, dyeing, setting and/or rolling (packing) after the circular knitting process described herein. In some embodiments, fabric 10 undergoes finishing processes, such as, for example, dyeing, setting and/or rolling (packing) before the circular knitting process described herein. In some embodiments, fabric 10 undergoes finishing processes, such as, for example, dyeing, setting and/or rolling (packing) during the circular knitting process described herein. In some embodiments, fabric 10 undergoes a finishing process at yarn stage as well when fabric 10 is dyed, for example. In some embodiments, the heat setting is done at about 120° C. at about 10 yards/minute. In some embodiments, fabric 10 is washed before, during or after the circular knitting process described herein. In some embodiments, fabric 10 is washed at a pH level of about 2.0 to about 9.0. In some embodiments, the washing at a pH level of about 2.0 to about 9.0 is a pre-treatment wherein pH levels are acidic or faintly acidic for health and to be comfortable to the skin. In some embodiments, fabric 10 is washed at a pH level of about 4.0 to about 7.0. In some embodiments, fabric 10 is treated with a mixing agent before, during or after the circular knitting process described herein. In some embodiments, the mixing agent is a smoothing agent. In some embodiments, the mixing agent comprises dimethyl terephthalate, ethylene glycol and/or polyethylene glycol. In some embodiments, the mixing agent is applied at an amount between about 1% to about 10%. In some embodiments, the mixing agent is applied at an amount between about 4% to about 6%. In some embodiments, the mixing agent is applied at an amount of about 5%. In some embodiments, the mixing agent is applied at an amount greater than about 10%.

As used herein, ultra-high weight molecular polyethylene includes a material that are a subset of the thermoplastic polyethylene. Ultra-high weight molecular polyethylene may also be referred to as high-modulus polyethylene or high-performance polyethylene. Ultra-high weight molecular polyethylene has extremely long chains. Ultra-high weight molecular polyethylene is a type of polyolefin having a melting point of about 130° C. to about 136° C. (266° F. to 277° F.). Ultra-high weight molecular polyethylene has very high thermal conductivity properties that feel cool to the touch. Ultra-high weight molecular polyethylene provides thermal conduction while transferring heat away from a user's body. Heat flows from source to sink, such as, for example, from a warmer or hotter body to a cooler or colder body. When used in bedding, the hotter body is the human body and the colder body is a fabric the bedding is made from, the fabric comprising ultra-high weight molecular polyethylene. Ultra-high weight molecular polyethylene has a very high rate of thermal conduction, which creates a temperature differential/gradient between the human body and a surface of the fabric, thus allowing heat to diffuse from the human body to the fabric. Over time temperature differences decay and a thermal equilibrium is achieved to help the user achieve a restful sleep with long lasting cooling.

As used herein, polyester includes a polyester fiber that is derived from terephthalic acid. Polyester is man-made fine, regular and translucent filament or staple fiber. It is formed into a fiber by extruding the heated polymer through a spinneret. This results in the fiber taking the cross-section of the spinneret. Regular polyester fiber differs from moisture wicking polyester based on the cross section of the fiber. The cross section of a regular polyester is circular, rod like appearance with a uniform diameter while moisture wicking polyester fiber cross section has ditches/grooves e.g. star shape.

As used herein, moisture wicking polyester is a functional polyester fiber with a special cross section where polymer is extruded with ditches around the four edges, which speeds up the moisture absorption and diffusion. The ditches provide spaces between the polymers that create channels for fast moisture wicking. As compared to regular polyester, nylon and cotton, the cross section of moisture wicking polyester provides higher vertical moisture wicking and diffusion. Moisture wicking polyester may include yarns having 50, 75, 100, 150 and 200 deniers.

As used herein, viscose includes semi-synthetic fibers that are obtained by treating cellulose with a caustic alkali solution and carbon sulfide. It is used in manufacturing regenerated cellulose fibers, sheets, or tubes, such as, for example, rayon or cellophane.

As used herein, phase change material include reactive microencapsulated materials that possess the ability to change their physical state (phase) from “solid to liquid” and from “liquid to solid”, within a certain temperature range, in response to ambient temperature differences. Phase change materials absorb heat when the temperature goes up, stores this energy temporarily, and releases the energy as heat when the temperature cools down.

In one embodiment, shown in FIGS. 1-3, fabric 10 includes a layer 12 comprising yarns 14 made from a first material, a layer 16 comprising yarns 18 made from a second material, and a layer 20 comprising yarns 22 made from a third material. At least one of the first, second and third materials comprises ultra-high weight molecular polyethylene. Layer 16 is positioned between layer 12 and layer 20 such that layer 16 provides loft of float between layer 12 and layer 20. In some embodiments, layer 16 includes thick yarns with a high thread count, such as, for example, 600 D, 900 D, 1200 D, 1500 D, 2400 D or higher. Such thicknesses of the yarns help to create loft. Layer 16 also provides loft or float because the yarns that layer 16 is made from do not get knitted by needles to form a pattern. Instead, the yarns are fed between layers 12 and 14 and are held by layers 12 and 14. In some embodiments, layer 16 is knitted and/or woven with layer 12 and layer 20 such that yarns 18 are woven with yarns 14 and yarns 22, as shown in FIG. 2. In some embodiments, layer 16 is positioned between layer 12 and layer 20 such that an outer surface 16a of layer 16 engages an inner surface 12a of layer 12 and an outer surface 16b of layer 16 engages an inner surface 20a of layer 20, as shown in FIG. 3. Surface yarns (e.g., yarns that make up layer 12) stay in their place and bottom yarns (e.g., yarns that make up layer 14) come to layer 12 and back again to form surface patterns and leave stitches behind in form of a pattern. Filler yarns (e.g., yarns that make up layer 16) are simply fed between the layers 12, 14 as the bottom yarns go back and forth to create a pattern on top to hold the two layers together. This bottom yarn patterning process helps filler yarns to stay intact. In some embodiments, filler yarns are pulled to the surface as well to form part of a pattern. In some embodiments, surface yarns do not go to the bottom.
