Description

FIELD OF TECHNOLOGY

The present invention relates generally to cooling textiles, and more particularly to three-layer circular knitted jacquard textile fabrics made from different yarns to provide a cooling effect on the body of a wearer or part thereof lying on such textiles. The application includes bedding made from such textile materials and methods of using them.

BACKGROUND OF THE INVENTION

Sleep is a very important process for people to experience and ensure they are at their best in every aspect of their lives. Sleep is an essential pathway for better health and personal goals. Indeed, sleep affects all aspects from business qualities to the firm memorization of new information to increase wages. Thus, it is essential for people to use bedding that is personalized, both to provide the sleep conditions for a particular person and body type, to achieve a comfortable, restful sleep.

Choosing the right type of bedding is an important aspect to ensure a good night's sleep. For example, selecting a pillow, mattress, mattress topper, mattress cover, and the like that provide a cool feeling because they absorb the heat generated by the user's body can greatly influence the comfort of users while they sleep. The feeling of coolness from such bedding can be controlled by choosing bedding made from textile fabric or other material that provides the desired level of coolness. Cooling textiles or other materials may be formed from materials such as, for example, various foams or gels. However, conventional cooling textiles used in bedding are known to cause a stiff or otherwise uncomfortable feeling to the touch, which can interfere with restful sleep. The present invention provides improvements to these prior art technologies.

It is envisaged that the viscose can be impregnated with a phase change material and/or can be wetted with a phase change material. In some embodiments, the wicking polyester was a high performance polyester. Its cross section is different from regular polyester fiber. Moisture-absorbing polyester fiber has a "cross" shape with many depressions around its circumference. Depressions formed by using channels with a specially created cross-section and located one behind the other, through which the process of transport and diffusion of moisture is accelerated. Absorbent channels in the fiber and between the fibers of the threads quickly move sweat to the surface of the textile fabric, where it evaporates. This cross-section also creates a large surface area that takes moisture in and away from the body, spreading it outward for easy evaporation on the outside of the textile web through capillary action over a wider surface area. Moisture-wicking polyester fiber can also be bonded to a moisture-wicking finishing material on the surface of the textile web or textile web's unique design to control the temperature to achieve a balanced temperature to prevent overheating.

In the embodiments discussed herein, wherein the textile web comprises ultra-high molecular weight polyethylene and a filler such as wicking polyester and/or viscose fiber with a phase change material; where a phase change material is used to provide a long lasting cooling effect. Once the heat is transferred from the wearer's body to the textile material, the molecules of the phase change material meet with the ultra-high molecular weight polyethylene, which acts as a heat source. This heat exchange between the wearer's body and the molecules of the phase change material causes the core of the phase change material to change from a solid state to a liquid state to create a cool sensation. When the heat source is removed, for example by removing the wearer's body from the textile web, the core of the phase change material emits stored latent heat and solidifies. As a result, the cooling capacity of the molecule is restored. As such, the phase change material acts as a body heat storage mechanism, thus allowing the ultra-high molecular weight polyethylene to constantly exchange heat. In some embodiments, the phase change material is provided to absorb excess body heat, providing an insulating effect created by the heat emission of the phase change material into the textile web, and to provide a heat regulating effect whereby the microclimate temperature is maintained near a constant value. It is envisaged that any of the layers and/or any of the filaments may be impregnated with a phase change material and/or may be wetted with a phase change material.

In one embodiment, in accordance with the principles of the present invention, the bedding product comprises first and second panels, where a cavity is defined between the inner surfaces of the panels; and in the cavity is a filler, where at least one of the panels is made of one or more of the textile materials discussed in this description. In one embodiment, in accordance with the principles of the present invention, the bedding product is selected from the group consisting of: mattress covers, mattresses, pillows, sheets and duvets. In one embodiment, in accordance with the principles of the present invention, the bedding product comprises an insert positioned between the first panel and the second panel such that the first panel is spaced from the second panel by the insert.

The following discussion contains a description of a three-layer circular knitted jacquard textile fabric 10, providing a cooling effect when used as a bedding. Alternative embodiments are also disclosed. Detailed reference is made below to exemplary embodiments of the present invention.

The components of the textile web 10 may be made from materials containing polymers and/or composites, depending on the particular application. For example, the textile web 10 may be made from materials such as: fabrics or textile materials, threads, fibers, paper or paperboard, cellulose-based materials, biodegradable materials, plastics and other polymers, semi-solid and solid materials. The textile web 10 may also be made from a heterogeneous material, such as a combination of two or more of the materials disclosed above. The web 10 and/or its components may be knitted, woven, extruded, molded, injection molded, cast, molded, and/or machined.

Fabric 10 is a three-layer circular knitted jacquard textile fabric, as discussed in this description. In some embodiments, the process for making a circular knit fabric comprises knitting in the round a yarn or other material to form a textile web, such as a textile web 10. Knitting in the round may include forming knitting needles into a knitting system. With the help of knitting needles, a circular knitted textile fabric is made, which has a tubular shape with a cylinder center. The circular knitted textile web is then cut to form a textile web 10 such that the textile web 10 has a square or rectangular shape. This enables the textile web 10 to be formed from a single continuous piece of finished textile web made using a knitting process in the round. As such, the textile web 10 can extend from the first side surface to the second side surface without any seams between the first side surface and the second side surface. The textile web 10 may also extend from the top surface to the bottom surface without any seams between the top surface and the bottom surface.

In some embodiments, the textile web 10 is subjected to finishing processes such as dyeing, shrinking and/or rolling (packaging) after the tubular knitting process disclosed herein. In some embodiments, the textile web 10 is subjected to finishing processes such as dyeing, shrinking and/or rolling (packaging) prior to the tubular knitting process disclosed herein. In some embodiments, the textile web 10 is subjected to finishing processes such as dyeing, shrinking and/or rolling (packaging) during the tubular knitting process disclosed herein. In some embodiments, the textile web 10 is subjected to finishing processes during the yarn processing step as well as, for example, when the textile web 10 is dyed. /min). In some embodiments, the textile web 10 is washed before, during, or after the circular knitting process disclosed herein. In some embodiments, the textile web 10 is washed at a pH of about 2.0 to about 9.0. In some embodiments, washing at a pH level of about 2.0 to about 9.0 is a pretreatment where the pH levels are acidic or mildly acidic for health and skin comfort. In some embodiments, the textile web 10 is washed at a pH level of about 4.0 to about 7.0. In some embodiments, the textile web 10 is treated with a blending agent before, during, or after the manufacturing process for the tubular material disclosed herein. In some embodiments, the blending agent is a smoothing agent. In some embodiments, the implementation of the mixing agent contains dimethyl terephthalate, ethylene glycol and/or polyethylene glycol. In some embodiments, the mixing agent is introduced in an amount of from about 1% to about 10%. In some embodiments, the implementation of the mixing agent is injected in an amount of from about 4% to about 6%. In some embodiments, the implementation of the mixing agent is injected in an amount of about 5%. In some embodiments, the implementation of the mixing agent is injected in an amount greater than about 10%.

As used herein, ultra-high molecular weight polyethylene comprises a material that is a type of thermoplastic polyethylene. Ultra high molecular weight polyethylene can also be referred to as high modulus polyethylene or high activity polyethylene. Ultra high molecular weight polyethylene contains very long chains. Ultra-high molecular weight polyethylene is a type of polyolefin having melting points of about 130°C to about 136°C (about 266°F to about 277°F). Ultra High Molecular Weight Polyethylene has a very high thermal conductivity, resulting in a cool feeling to the touch. Ultra high molecular weight polyethylene provides thermal conductivity and removes heat from the wearer's body. Heat travels from a source to an object of lower temperature, such as from a warmer or hotter body to a colder or colder body. When using bedding, the hotter body is the human body, and the colder body is the textile web of the bedding made from the textile web containing ultra-high molecular weight polyethylene. The ultra-high molecular weight polyethylene has a very high rate of heat conduction, thereby creating a temperature differential/gradient between the human body and the surface of the textile web, thus allowing heat to be dissipated from the human body to the textile material. Over time, the temperature difference decreases and thermal equilibrium is reached, which contributes to the achievement of a restful sleep of the user with a long-lasting cooling.

When used in this description, the polyester contains a polyester fiber derived from terephthalic acid. Polyester is a man-made, thin, regular and transparent filament or staple fiber. It is spun into fiber by extruding a heated polymer through a die. This results in a fiber having a cross section similar to the shape of the spinneret opening. Regular polyester fiber differs from moisture wicking polyester fiber based on the cross section of the fiber. The cross-section of a regular polyester fiber has a round, rod-like appearance with a uniform diameter, while the cross-section of a moisture-wicking polyester fiber contains depressions/grooves and has, for example, a star shape.

As used herein, a moisture-wicking polyester fiber is a functional polyester fiber with a particular cross-section where the polymer is extruded through an opening with cavities around four edges, whereby moisture absorption and dissipation is accelerated. The depressions provide spaces between the parts of the polymer, as a result of which channels are created for the rapid absorption of moisture. Compared to regular polyester, nylon and cotton, the moisture-wicking polyester's cross-section provides higher vertical moisture absorption and dispersion. The moisture absorbent polyester may include 50, 75, 100, 150 and 200 denier yarns (1 denier = 1.11 dtex).

As used herein, viscose contains semi-synthetic fibers obtained by treating cellulose with a solution of caustic soda and carbon disulfide. It is used in the production of regenerated cellulose fibers, sheets or pipes, such as viscose or cellophane.

As used herein, a phase change material comprises reactive microencapsulated materials having the ability to change their physical state (phase) from “solid to liquid” and from “liquid to solid”, within a certain temperature range, within response to ambient temperature differences. Phase change materials absorb heat as the temperature rises, store that energy temporarily, and release energy as heat as the temperature falls.

In one embodiment shown in Figures 1-3, the textile web 10 comprises a layer 12 containing yarns 14 made from a first material; layer 16 containing threads 18 made from the second material; and a layer 20 containing threads 22 made from the third material. At least one of the first, second and third materials contains ultra-high molecular weight polyethylene. Layer 16 is positioned between layer 12 and layer 20 such that layer 16 provides elastic movement between layer 12 and layer 20. In some embodiments, layer 16 contains thick filaments with a high linear thread density, for example: 600D, 900D, 1200D, 1500D , 2400D or higher (D - denier). By using such thick filaments, elasticity is provided. Through the use of layer 16, elasticity or mobility is also provided, since the threads of this layer 16 are made of non-needle knitted threads with the formation of a pattern. Instead, the yarns are fed between layers 12, 14 and held by layers 12 and 14. In some embodiments, layer 16 is bonded and/or woven with layer 12 and layer 20 such that yarns 18 are intertwined 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 outer surface 16a of layer 16 mates with inner surface 12a of layer 12 and outer surface 16b of layer 16 mates with inner surface 20a of layer 20, as shown in FIG. 3. The surface threads (for example, the threads that form layer 12) are left in place, and the bottom threads (for example, the threads that form layer 14) are brought to layer 12 and returned back to form the surface patterns and leave the stitches behind to form the pattern. . The filler threads (eg, the threads that form layer 16) are simply fed between layers 12, 14 while the bottom threads are fed back and forth to create a pattern on the top to hold the two layers together. Through this patterning process, the use of the bobbin threads helps to keep the filler threads in place. In some embodiments, the filler threads are pulled towards the surface as well as to form part of the pattern. In some embodiments, the implementation of the surface threads are not retracted down.

In one embodiment, in accordance with the principles of the present invention, the first material comprises ultra-high molecular weight polyethylene and the second and third materials comprise polyester.
