Description

Technical Field

[0001] The utility model relates to the technical field of textile manufacturing, in particular to a skin-friendly cooling mat fabric with temperature regulating function and a cooling mat. Background Art

[0002] With the improvement of living standards and people's growing demand for quality of life, the functionality and comfort of cooling mats, as a common daily necessity in summer, have received more and more attention.

[0003] Traditional cooling mats include bamboo mats, straw mats, and mahjong mats. With the widespread use of indoor air conditioning in summer, traditional cooling mats are too cold to use in air-conditioned environments, making them unsuitable for people with frail health or temperature sensitivity, such as the elderly, children, and women. Existing all-cotton soft cooling mats are typically made of coarse cloth, woven with coarse yarn and a heavy plain weave. This can be rough on the skin and can easily cause discomfort for infants and those with sensitive skin. Furthermore, the cooling effect is achieved through the granular texture created by the weaving structure, which can provide a less than optimal cooling experience.

[0004] As consumers have higher and higher requirements for the comfort and functionality of cooling mats, there is an urgent need for a cooling mat that is comfortable to the touch and has an appropriate cool feeling when used. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide a skin-friendly and temperature-regulating device.

[0006] The utility model adopts the following technical solutions:

[0007] The utility model discloses a skin-friendly summer mat fabric with a temperature-regulating function, comprising a knitted surface layer treated with liquid ammonia and a woven surface layer containing phase-change microcapsules, wherein both the knitted surface layer and the woven surface layer are made of pure cotton material. It should be noted that the knitted fabric is formed by interlacing one or more yarns through knitting needles. The characteristic of this structure is that the yarn forms a ring structure in the fabric, so the knitted fabric has good elasticity, ductility, breathability and softness, and is more comfortable and skin-friendly; the woven fabric is formed by interlacing warp yarns and weft yarns, and the woven fabric is usually tighter and smoother than the knitted fabric. The woven fabric has the advantages of wear resistance and strong stability. The woven fabric structure has a distinct texture and has strong heat absorption, heat conduction and heat dissipation; the knitted surface layer and the woven surface layer are both made of pure cotton material and are relatively skin-friendly; in addition, the knitted surface layer is treated with liquid ammonia to further improve the softness of the fabric. , and improve the cool touch feeling of the fabric; phase change microcapsule is a material that encapsulates phase change material into tiny particles through microcapsules. The microcapsule wrapping can protect the phase change material from the influence of the external environment and make it easier to add to textiles, etc. The woven surface layer contains phase change microcapsules, which can use the phase transition of the phase change material to absorb and release heat to achieve temperature regulation. When the temperature reaches the melting point of the phase change material contained in the fabric, the phase change material absorbs heat and converts from solid to liquid, causing the fabric to heat up later; when the external temperature reaches the crystallization point of the phase change material contained in the fabric, the phase change material again undergoes phase transition and converts from liquid back to solid, and the heat released can delay cooling.

[0008] In one implementation of the present invention, the knitted surface layer is made of single yarn with a fineness of 20S to 100S, thereby improving the softness and comfort of the fabric.

[0009] In one implementation of the present invention, the woven surface layer is made of a plurality of single yarns with a fineness of 20S to 60S, which is conducive to improving the strength, durability and wrinkle resistance of the fabric.

[0010] In one implementation of the present invention, the woven surface layer is made of a plurality of strands of single yarn with a fineness of 20S to 60S that are plied together.

[0011] In one implementation of the present invention, the woven surface layer is made of two strands of single yarn with a fineness of 20S to 40S, or is made of three strands of single yarn with a fineness of 60S to 80S.

[0012] In one embodiment of the present invention, an intermediate layer is further included between the knitted surface layer and the woven surface layer, and the knitted surface layer and the woven surface layer are fixed to each other by the intermediate layer. It should be noted that for larger-sized summer mat products, traditional quilting is not suitable. The two fabrics are combined through a composite process to achieve a stable bond, good washability, and less prone to delamination.

[0013] In one implementation of the present invention, the intermediate layer is a hot melt adhesive or a microporous membrane, and the intermediate layer contains a microporous structure. It should be noted that the microporous structure is conducive to draining moisture from the skin and maintaining thermal and moist comfort of the skin.

[0014] In one embodiment of the present invention, the microporous membrane comprises at least one of a polytetrafluoroethylene (PTFE) membrane, a polyurethane (PU) membrane, a polyester (PU) membrane, a polypropylene (PP) membrane, and a polyethylene (PE) membrane. It should be noted that the composite membranes can impart waterproof and breathable properties to the fabric, thereby enhancing user comfort.

[0015] In one implementation of the present invention, the knitted surface layer and the woven surface layer are fixed to each other by quilting lines. It should be noted that for a smaller-sized summer mat, the two layers of fabric are fixed to each other by quilting, which is easy to operate and has a strong bond.

[0016] In one implementation of the present invention, the mat fabric is reversible. It should be noted that both sides of the mat fabric have a cool feel, with different body sensations. The knitted surface layer feels delicate, silky, and cool to the touch, while the woven surface layer on the other side has a supporting function and a phase change energy storage function. When used as a direct skin contact layer, the knitted surface layer is skin-friendly, soft, and provides a direct cool feeling. At the same time, the phase change material in the woven surface layer avoids direct contact with the skin, which can reduce friction and extend the use time of the phase change material. When used as a direct skin contact layer, the woven surface layer also provides a cool feeling to the touch.

[0017] The present invention also provides a skin-friendly cooling mat with a temperature-regulating function, comprising the aforementioned cooling mat fabric, and having a rim wrapped around the periphery of the cooling mat, wherein the rim is made of a pure cotton woven fabric. It should be noted that the rim helps to relatively secure the knitted surface layer and the woven surface layer, and the woven fabric helps to provide friction and maintain the shape of the cooling mat, thereby reducing displacement or deformation during use. The rim is made of pure cotton and is relatively skin-friendly and comfortable.

[0018] Due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0019] According to the utility model, a cooling mat fabric and a cooling mat can be provided which are comfortable, skin-friendly, have a suitable cool feeling and have a temperature regulating function. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The present invention is further described in detail below through specific embodiments in conjunction with the accompanying drawings. In the following embodiments, many detailed descriptions are intended to enable the present invention to be better understood. However, those skilled in the art can easily recognize that some of the features can be omitted in different situations, or can be replaced by other materials or methods. In some cases, some operations related to the present invention are not shown or described in the specification. This is to avoid the core part of the present invention being overwhelmed by too much description. For those skilled in the art, it is not necessary to describe these related operations in detail. The related operations can be fully understood based on the description in the specification and the general technical knowledge in the field.

[0025] In addition, the features, operations, or characteristics described in the specification may be combined in any appropriate manner to form various embodiments. Furthermore, the steps or actions in the method description may be reordered or adjusted in a manner readily apparent to those skilled in the art. Therefore, the various sequences in the specification and drawings are provided solely for the purpose of clearly describing a particular embodiment and are not intended to be mandatory, unless otherwise specified.

[0026] A cool mat is a type of bedding. A traditional cool mat refers to a bamboo mat or straw mat, a mahjong cool mat, etc., which is laid out in the summer for cooling. With the widespread use of indoor air conditioning in the summer, using a traditional cool mat in an air-conditioned environment is too cold and is not suitable for people who are weak or sensitive to temperature, such as the elderly, children, and women. In addition, a traditional cool mat is not easy to clean and is prone to bacterial growth. Existing all-cotton old coarse cloth cool mats are generally woven with coarse yarn strands and a heavy plain weave. Multiple weft yarns are inserted during the wefting process, and the multiple yarns are interwoven with a heavy plain weave structure. When used, they feel hard and heavy, and have poor tactile comfort during use. They are not suitable for infants and people with sensitive skin. In view of this, the present invention proposes a cool mat fabric and a cool mat. The knitted fabric and woven fabric of the present invention are compounded together by a microporous membrane. The surface layer uses a knitted fabric with a cool touch feeling, and the middle layer uses a film with a microporous structure. The microporous structure is conducive to extracting moisture from the skin and maintaining skin thermal comfort. The bottom layer uses a woven fabric with a supporting effect and has a temperature-regulating phase change function. The mat product has a cool feeling on both sides and can be used on both sides, and the two sides have different body sensations. The knitted fabric on the surface feels delicate and silky and has a cool feeling to the touch. The bottom layer has multi-functions - support, antibacterial, mildew-proof, anti-mite function, phase change energy storage, etc. The temperature between the human body and the mat is kept within a comfortable range, cool but not icy, and has a temperature regulation function. When the surface layer is used as a direct contact layer with the skin, the knitted structure is soft, skin-friendly and soft, and has a cool feeling when directly contacted; when the bottom layer is used as a direct contact surface, it also has a cool feeling when directly contacted, which improves the user's experience of the all-cotton soft mat, improves the practicality and usability of the all-cotton soft mat, and solves the problem that the existing all-cotton old coarse cloth soft mat is not cool enough to use and has a poor experience effect. The new structure mat of the utility model does not deform after multiple washings, and at the same time solves the problem that the soft mat products made of conventional single fabrics are not formed.

[0027] Hereinafter, the cooling mat fabric and the cooling mat of the present invention will be described in detail with reference to specific embodiments and accompanying drawings.

[0028] Figure 1 It is a structural schematic diagram of an embodiment of the summer mat fabric 100 involved in the present invention.

[0029] like Figure 1 As shown, in a specific embodiment, the mat fabric 100 may include a knitted surface layer 11 and a woven surface layer 12. It should be noted that the knitted fabric is formed by interlacing one or more yarns through knitting needles. The characteristic of this structure is that the yarn forms a ring structure in the fabric, so the knitted fabric has good elasticity, ductility, breathability and comfort; the woven fabric is formed by interlacing warp yarns and weft yarns. The woven fabric is usually tighter and smoother than the knitted fabric. The woven fabric has the advantages of wear resistance and strong stability. The woven fabric structure has a distinct texture and has strong heat absorption, heat conduction and heat dissipation.

[0030] In a specific embodiment, the knitted surface layer 11 and the woven surface layer 12 are both made of pure cotton material, thereby having good air permeability and comfort.

[0031] In one embodiment, the knitted surface layer 11 is a knitted fabric treated with liquid ammonia.

[0032] In a specific embodiment, the coolness coefficient of the knitted surface layer 11 is ≥ 0.15 J / (cm 2 ·s). The cooling coefficient test method is carried out in accordance with GB / T 35263-2017.

[0033] In a specific embodiment, the coolness coefficient of the knitted surface layer 11 is ≥ 0.2 J / (cm 2 ·s).

[0034] In one embodiment, the woven surface layer 12 is a woven fabric containing phase change microcapsules.

[0035] In one embodiment, the cooling coefficient of the woven surface layer 12 is ≥ 0.15 J / (cm 2 ·s).

[0036] In one embodiment, the cooling coefficient of the woven surface layer 12 is ≥ 0.2 J / (cm 2 ·s).

[0037] In a specific embodiment, the phase change materials (PCM) in the phase change microcapsules can be paraffin, fatty acids, normal alkanes, etc.

[0038] In one specific embodiment, the phase change temperature of the phase change material is 28°C to 31°C. It should be noted that when used in an air-conditioned room, the phase change temperature-regulating fabric utilizes the phase transition of the phase change material to absorb and release heat to achieve temperature regulation: when the temperature reaches the melting point of the phase change material contained in the fabric, the phase change material absorbs heat and transforms from solid to liquid, causing the fabric to heat up more slowly; when the external temperature reaches the crystallization point of the phase change material contained in the fabric, the phase change material undergoes another phase transition, transforming from liquid back to solid, and the heat released can again delay cooling.

[0039] In a specific embodiment, the knitted surface layer 11 is made of single yarn with a fineness of 20S to 100S.

[0040] In a specific embodiment, the woven surface layer 12 is made of a plurality of single yarns with a fineness of 20S to 60S.

[0041] In a specific embodiment, the woven surface layer 12 can be made of two strands of single yarn with a fineness of 20S to 40S.

[0042] In a specific embodiment, the woven surface layer 12 can be made of three strands of single yarn with a fineness of 60S to 80S.

[0043] In a specific embodiment, the knitted surface layer 11 and the woven surface layer 12 are fixed to each other.

[0044] In a specific embodiment, the cooling mat fabric 100 may include a middle layer 13 , and the knitted surface layer 11 and the woven surface layer 12 are fixed to each other via the middle layer 13 .

[0045] In one embodiment, the middle layer 13 comprises a microporous structure.

[0046] In a specific embodiment, the middle layer 13 is a hot melt adhesive or a microporous film. It should be noted that the middle layer 13 can be a continuous film layer or a discontinuous film layer. For example, when the hot melt adhesive is dot-coated or unevenly coated, a discontinuous film layer may appear.

[0047] In a specific embodiment, the microporous membrane includes at least one of a polytetrafluoroethylene (PTFE) membrane, a polyurethane (PU) membrane, a polyester (PU) membrane, a polypropylene (PP) membrane, and a polyethylene (PE) membrane.

[0048] In a specific embodiment, the thickness of the knitted surface layer 11 is 0.2 mm to 1 mm. Preferably, the thickness of the knitted surface layer 11 is 0.40 mm to 0.61 mm.

[0049] In a specific embodiment, the thickness of the intermediate layer 13 is 0.01 mm to 1 mm.

[0050] In a specific embodiment, the thickness of the woven surface layer 12 is 0.2 mm to 2 mm. Preferably, the thickness of the woven surface layer 12 is 0.75 mm to 0.95 mm.

[0051] In one specific embodiment, the mat fabric 100 can be used on both sides. It should be noted that both sides of the mat fabric 100 have a cool feeling, with different body sensations. The knitted surface layer 11 has a delicate, silky touch and a cool contact feeling, while the woven surface layer 12 on the other side has a supporting function and a phase change energy storage function. When used as a direct skin contact layer, the knitted surface layer 11 is skin-friendly and soft, and has a direct contact cool feeling. At the same time, the phase change material in the woven surface layer 12 avoids direct contact with the skin, which can reduce friction and extend the use time of the phase change material. When used as a direct skin contact layer, the woven surface layer 12 also has a cool contact feeling.

[0052] Figure 2 It is a structural schematic diagram of another embodiment of the summer mat fabric 100 involved in the present invention.

[0053] like Figure 2As shown, in a specific embodiment, the knitted surface layer 11 and the woven surface layer 12 can be fixed to each other by quilting lines 14. In other words, the mat fabric 100 may not have the middle layer 13, and the knitted surface layer 11 and the woven surface layer 12 are not fixed to each other by the middle layer 13. It should be noted that quilting is a sewing technique that fixes two or more layers of fabric together by sewing lines. The sewing methods include: straight quilting: sewing with parallel straight lines; pattern quilting: sewing according to a specific design or pattern, such as diamonds, squares, flowers, etc.; freestyle quilting: irregular sewing lines can create a more natural or abstract effect. It should also be noted that the mat fabric 100 of the present invention has a very different softness between the surface knitted fabric and the bottom woven fabric. The combination of the two materials places high demands on the quilting process. The existing quilting equipment limits the general single-needle quilting process, which is prone to needle breakage, discontinuity, and difficulty in operation. Therefore, the traditional quilting process is not suitable for large-sized mat products. The two fabrics can be compounded through a composite process, which has a stable combination, good washability, and is not prone to stratification. For small-sized mat products used in children's and toddler beds, this can be achieved through quilting.

[0054] This embodiment also provides a cool mat 200. Figure 3 It is a structural schematic diagram of the cooling mat 200 involved in the present invention.

[0055] In a specific embodiment, the cooling mat 200 includes the cooling mat fabric 100 described above.

[0056] like Figure 3 As shown, in a specific embodiment, the cooling mat 200 may include a cooling mat body 21 .

[0057] In one embodiment, the mat body 21 is made of a mat fabric 100 .

[0058] In a specific embodiment, the mat body 21 is a mat fabric 100 .

[0059] In a specific embodiment, the cool mat 200 is 70 cm to 220 cm long and 50 cm to 200 cm wide.

[0060] In a specific embodiment, the cooling mat 200 may include a rim 22 .

[0061] In one embodiment, the cooling mat 200 is surrounded by a rim 22 .

[0062] In a specific embodiment, the binding edge 22 is connected to both the knitted surface layer 11 and the woven surface layer 12 of the mat fabric 100 , so that the binding edge 22 covers the side edge of the mat 200 .

[0063] In one embodiment, the binding 22 is made of pure cotton woven fabric. It should be noted that the binding helps to relatively fix the knitted surface layer and the woven surface layer. The woven fabric helps to provide friction and maintain the shape of the cool mat 200, reducing the possibility of displacement or deformation during use of the cool mat 200. The pure cotton material is relatively skin-friendly and comfortable.

[0064] In a specific embodiment, the cooling mat 200 may include a fixing belt 23 .

[0065] In a specific embodiment, the cooling mat 200 can be matched with the size of the bed, and fixing straps 23 are respectively provided at the four corners of the cooling mat 200 to fix the cooling mat 200 relative to the bed, thereby preventing the cooling mat 200 from slipping during use.

[0066] In a specific embodiment, the fixing belt 23 may be elastic or retractable, thereby facilitating matching with mattresses of different thicknesses.

[0067] The present invention will be further described below with reference to specific examples. It should be understood that the examples are merely illustrative and do not limit the scope of protection of the present invention. Unless otherwise specified, the materials and instruments used in the examples are all commercially available, and the operations are performed according to common methods in the art.

[0068] Example 1

[0069] (1) The surface layer is a knitted surface layer:

[0070] The surface layer is made of 50S / 1~100S / 1 high count and high density double-sided cotton fabric with a gram weight of 100g / m 2 ~180g / m 2 , the specific process is as follows:

[0071] Yarn: High count yarn 50S / 1~100S / 1, with long-staple cotton ratio ≥50%, using compact spinning process, the yarn surface is smooth and less hairiness;

[0072] Weaving method: Double-sided weft knitting process. The weft knitting process is to feed one or more yarns into the working needles of the knitting machine from the weft direction, so that the yarns are sequentially bent into loops and then strung together to form a weft knitted fabric.

[0073] Dyeing and finishing process: The fabric is treated with liquid ammonia and mercerized to achieve a cool touch effect similar to liquid ammonia fabric. Specifically, the fabric is immersed in liquid ammonia for 10 minutes and then dried immediately. Then, a 200g / L sodium hydroxide solution is prepared and immersed in the lye for 10 minutes at room temperature. The fabric is then washed with water three times and dried.

[0074] Cooling test: The fabric was tested before washing, after washing 10 times, and after washing 100 times. The test method was carried out in accordance with GB / T 35263-2017. The results showed that the cooling coefficient was ≥0.24, and the contact cooling sensation of the fabric after multiple washings met the Q-max ≥0.15J / (cm 2 ·s), it still has a cool touch effect after 100 washes.

[0075] (2) Middle layer: It is made by hot melt adhesive double-point compounding process without adding film. Hot melt adhesive is a single-component reactive hot melt adhesive with a solid content of 100%. It does not contain any chemical solvents. As an adhesive, hot melt adhesive has the advantages of being environmentally friendly, non-toxic and odorless.

[0076] (3) The bottom layer is a woven surface layer:

[0077] The bottom layer is made of woven twill weave.

[0078] Fabric weaving process: spinning - weaving - dyeing / printing - functional finishing - finished product - packaging;

[0079] Yarn: Compactly spun yarn with cool feeling, antibacterial, mildew and mite proof functions, 21S / 2-40S / 2 low count yarn strands;

[0080] Weaving method: Woven twill weave is used to enhance the feel and wear resistance;

[0081] Functional finishing in dyeing and finishing process: Before the cooling function finishing, the grey fabric is first subjected to singeing, desizing and tentering treatments. Then, the phase change material TEXSUN COOL-PCM and the cross-linking agent isocyanate are added, and the cooling function finishing is achieved by padding. The fabric is then baked at 120°C for 3 minutes in a tentering and setting device. The finished fabric is then processed in a pre-shrinking machine.

[0082] Cooling test: The fabric was tested for contact cooling coefficient before washing, after washing 10 times, and after washing 100 times. The test method was carried out in accordance with GB / T 35263-2017. The results showed that the cooling coefficient of the fabric after cooling treatment was 0.18~0.28J / (cm 2 ·s), and the cool feeling of the fabric after multiple washings meets Q-max ≥ 0.15J / (cm 2 ·s), it still has a cool touch effect after 100 washes; the enthalpy value meets the A-level requirements of phase change textiles.

[0083] Example 2

[0084] The surface layer is a knitted surface layer, which is a 20S / 1 to 40S / 1 single-sided knitted fabric that has just been treated with liquid ammonia. Single-sided knitted fabric: the extension lines or coils of the coils are concentrated on one side of the knitted fabric, which has a front and a back. The front and back of the knitted fabric have a large difference in appearance. The front looks smooth and flat, while the back is loose and rough. When compounded with the bottom layer, the back is combined with the middle layer. The front of the fabric is the side that directly contacts the skin and has a delicate touch and a significant cool feeling. The coolness coefficient is ≥0.2J / (cm 2 ·s).

[0085] The middle layer is the same as that in Example 1.

[0086] The bottom layer is woven with 60S / 3 to 80S / 3 high-count multi-strand yarns in a twill or heavy plain weave, which has cooling, antibacterial, mildew-proof, and anti-mite properties. The high-count multi-strand weaving of the fabric improves the softness and creates a more delicate surface. This structure improves the overall comfort of the fabric, with a contact coolness coefficient of ≥0.2; it provides a more comfortable experience when used as a skin-contact surface. The remaining processes are the same as in Example 1.

[0087] The above content is a further detailed description of the present invention in conjunction with specific implementation methods, and the specific implementation of the present invention cannot be considered to be limited to these descriptions. For those skilled in the art of the present invention, without departing from the concept of the present invention, they can make several simple deductions or substitutions, which should be considered to fall within the scope of protection of the present invention.
