Description

Technical Field

[0001] This utility model relates to the field of textile manufacturing technology, and in particular to a pure cotton fabric with moisture-wicking and heat-insulating functions. Background Technology

[0002] With continuous social progress and technological development, people have increasingly higher demands for clothing comfort. Synthetic fibers such as nylon and polyester are mostly hydrophobic, with poor moisture absorption and wicking capabilities, easily leading to stuffiness and lack of breathability when worn, especially in hot weather or during exercise when sweating and sticking to the skin, causing discomfort. Cotton fibers, on the other hand, are soft and skin-friendly, and have excellent moisture absorption and breathability, making them commonly used as clothing fabrics. However, traditional pure cotton fabrics have limited functionality and usually cannot simultaneously provide warmth and moisture wicking, failing to meet people's diverse clothing needs for various applications. Utility Model Content

[0003] To address the problem that existing pure cotton fabrics typically cannot simultaneously provide both warmth and moisture wicking, this invention provides a pure cotton fabric with both moisture-wicking and warmth-insulating functions. The technical solution adopted by this invention is as follows:

[0004] This utility model discloses a pure cotton fabric with moisture-wicking and heat-insulating functions. It is woven from cotton fibers and has a double-knitted structure, including an inner layer and an outer layer. The outer layer is a plain weave, and the inner layer is a jacquard weave with a perforated mesh structure. At least one of the inner and outer layers is loaded with phase change microcapsules. It should be noted that the fabric of this utility model, woven from cotton fibers, has good moisture absorption. Simultaneously, the jacquard weave design of the inner layer allows for moisture absorption and sweat removal in the skin-contacting portion, quickly absorbing sweat from the skin surface and transferring it to the outer layer for evaporation through capillary action between fibers, keeping the skin dry. The perforated mesh structure of the jacquard weave creates air trapping spaces; air is a poor conductor of heat, reducing heat transfer from the body to the outside and improving heat retention. The plain weave of the outer layer enhances the abrasion resistance of the pure cotton fabric. In addition, the fabric has phase change microcapsules, which enable the fabric to have dynamic temperature regulation capabilities of absorbing / releasing heat. When the ambient temperature rises, the phase change material changes from solid to liquid, absorbing heat and storing it inside the fabric; when the ambient temperature drops, the phase change material changes from liquid to solid, releasing the stored heat. Thus, it has a heat preservation effect, keeping the human body in a comfortable state.

[0005] In one embodiment of this utility model, the perforated mesh is regularly distributed in the inner layer.

[0006] In one implementation of this utility model, the shape of the perforated mesh is selected from at least one of the following: square, rhombus, hexagon, circle, and ellipse.

[0007] In one embodiment of this invention, the porosity of the jacquard fabric is 20% to 40%.

[0008] In one implementation of this utility model, the jacquard weave is a biomimetic honeycomb structure. It should be noted that a biomimetic honeycomb structure refers to an inner layer similar to a honeycomb structure, possessing a hexagonal perforated structure (the openwork mesh is hexagonal), capable of creating air-trapping spaces.

[0009] In one implementation of this invention, the warp and weft density of the plain weave is 120×70 threads / inch to 200×120 threads / inch. It should be noted that the high density of the plain weave provides good support and abrasion resistance.

[0010] In one embodiment of this utility model, the count of the cotton fiber is 50S to 100S.

[0011] In one implementation of this invention, the phase change microcapsules are distributed in the gaps, surface, and interior of the cotton fibers, and the particle size of the phase change microcapsules is 20nm to 200nm. Therefore, the phase change microcapsules in the fabric have good dispersibility, which is beneficial for providing more uniform temperature control. It should be noted that the small particle size of the phase change microcapsules helps maintain the softness of the cotton fibers.

[0012] In one embodiment of this invention, the all-cotton fabric is further loaded with a thermosensitive hydrogel. The thermosensitive hydrogel is distributed in the gaps, surface, and interior of the cotton fibers. The thermosensitive hydrogel swells at temperatures ≤32℃ and shrinks at temperatures >32℃. It should be noted that the thermosensitive hydrogel regulates its expansion or contraction through temperature changes, thereby adjusting the fabric's breathability and moisture absorption. For example, at low temperatures, the hydrogel swells to store moisture, and at high temperatures, it shrinks to release moisture and absorb heat. Simultaneously, it forms a thermosensitive hydrophilic-hydrophobic dynamic equilibrium surface, releasing moisturizing factors when the skin is dry and forming a breathable barrier when moist, thus regulating the microenvironment.

[0013] In one embodiment of this invention, the thermosensitive hydrogel is an N-isopropylacrylamide copolymer.

[0014] Due to the adoption of the above technical solutions, the beneficial effects of this utility model are as follows:

[0015] This new fabric, woven from cotton fibers, possesses excellent moisture absorption. The inner layer features a jacquard weave design; the portion of the jacquard in contact with the skin absorbs moisture and sweat quickly, transferring the moisture to the outer layer through capillary action between fibers for evaporation, keeping the skin dry. The jacquard weave also incorporates a perforated mesh structure, creating air pockets. Since air is a poor conductor of heat, this reduces heat loss from the body, enhancing insulation. The outer layer is a plain weave, improving the abrasion resistance of the pure cotton fabric. Furthermore, the fabric incorporates phase change microcapsules, enabling dynamic temperature regulation through heat absorption and release. When the ambient temperature rises, the phase change material changes from solid to liquid, absorbing and storing heat within the fabric; when the ambient temperature decreases, it changes back to solid, releasing the stored heat. This provides insulation, keeping the body comfortable. Attached Figure Description

[0018] The present invention will now be described in further detail with reference to specific embodiments and accompanying drawings. In the following embodiments, many details are described to facilitate a better understanding of the present invention. However, those skilled in the art will readily recognize that some features may be omitted in different situations, or may be replaced by other materials or methods. In some cases, certain operations related to the present invention are not shown or described in the specification. This is to avoid obscuring the core parts of the present invention with excessive description. For those skilled in the art, detailed description of these related operations is not necessary; the relevant operations can be fully understood based on the description in the specification and general technical knowledge in the art.

[0019] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments. At the same time, the steps or actions in the method description can be rearranged or adjusted in a manner obvious to those skilled in the art. Therefore, the various orders in the specification and drawings are only for the clear description of a particular embodiment and do not imply a necessary order, unless otherwise stated that a particular order must be followed.

[0020] The following describes in detail the all-cotton fabric (hereinafter sometimes simply referred to as "pure cotton fabric" or "fabric") with moisture-wicking and heat-insulating functions of this utility model, in conjunction with specific embodiments and accompanying drawings.

[0021] Figure 1 This is a structural breakdown diagram of the all-cotton fabric 100 with moisture-wicking and heat-insulating functions involved in this utility model.

[0022] like Figure 1 As shown, in one specific embodiment, the pure cotton fabric 100 can be a double-knitted structure, which may include an inner layer 10 and an outer layer 20.

[0023] In one specific embodiment, the inner layer 10 is a surface layer that is close to or in contact with the skin, and the outer layer 20 is a surface layer that is close to or in contact with the external environment.

[0024] In one specific embodiment, the inner layer 10 is a jacquard weave. A jacquard weave is a fabric structure that forms a pre-set pattern or design through a special weaving process.

[0025] In one specific embodiment, the jacquard weave has a perforated mesh structure 11. It should be noted that the perforated mesh can increase air circulation channels and improve the overall breathability of the fabric. In addition, the perforated mesh structure 11 can form air retention spaces. Since air is a poor conductor of heat, it can reduce the conduction of body heat to the outside and improve the heat preservation performance.

[0026] In one specific embodiment, the openwork mesh 11 is regularly distributed in the inner layer 10. This facilitates weaving. Of course, the openwork mesh 11 can also be irregularly distributed; for example, the jacquard weave can be a specific pattern (e.g., an animal cartoon pattern).

[0027] In one specific embodiment, the shape of the perforated mesh 11 is selected from at least one of the following: square, rhombus, hexagon, circle, and ellipse.

[0028] Figure 2 This is a schematic diagram of the inner layer structure of an embodiment of this utility model, as shown below. Figure 2 As shown, in one specific embodiment, the jacquard weave is a biomimetic honeycomb structure.

[0029] In one specific embodiment, the porosity of the jacquard fabric is 20% to 40%. For example, the porosity of the jacquard fabric can be 20%, 25%, 30%, 35%, or 40%. This allows the inner layer 10 to have a large surface area and pores, which helps to quickly absorb sweat from the skin surface.

[0030] In one specific embodiment, the outer layer 20 is a plain weave (with unidirectional continuous loops). This provides the cotton fabric 100 with a certain degree of protection (blocking external dust and wind and rain, while reducing the exposure of the inner mesh, improving the smoothness and abrasion resistance of the fabric) and support.

[0031] In one specific embodiment, the warp and weft density of the plain weave is 120×70 threads / inch to 200×120 threads / inch. This results in a high density, providing good support and abrasion resistance. For example, the warp and weft density of the plain weave can be 133×72 threads / inch.

[0032] In one specific embodiment, the cotton fiber count can be 50S to 100S. For example, the cotton fiber count can be 50S, 60S, 70S, 80S, 90S, or 100S.

[0033] In one specific embodiment, pure cotton fabric 100 is loaded with phase change microcapsules. It should be noted that phase change microcapsules are functional micro / nano-scale capsules based on phase change material (PCM) technology. The core principle is to encapsulate phase change materials (such as paraffin wax, fatty acids, etc.) and utilize their ability to absorb or release a large amount of latent heat during solid-liquid or liquid-solid phase transitions to achieve intelligent temperature control. Their structure typically consists of a core material (phase change material) and a wall material (polymer). The wall material protects the core material, controls phase change behavior, and maintains dispersion stability.

[0034] In one specific embodiment, at least one of the inner layer 10 and the outer layer 20 is loaded with phase change microcapsules. For example, both the inner layer 10 and the outer layer 20 may be loaded with phase change microcapsules.

[0035] In one specific embodiment, phase change microcapsules can be loaded onto fabric 100 or cotton fibers through coating finishing, printing process, spinning blending, impregnation treatment, etc.

[0036] In one specific embodiment, the phase change microcapsules may be distributed in at least one of the gaps, surface, and interior of the cotton fibers. Therefore, the phase change microcapsules in the fabric 100 can have good dispersibility, which is beneficial for providing more uniform temperature control.

[0037] In one specific embodiment, the particle size of the phase change microcapsules is 20 nm to 200 nm. For example, the particle size of the phase change microcapsules can be 20 nm, 50 nm, 100 nm, 100 nm, or 200 nm. It should be noted that the smaller particle size of the phase change microcapsules is beneficial for maintaining the softness of cotton fibers.

[0038] In one specific embodiment, the cotton fabric 100 is also loaded with a thermosensitive hydrogel.

[0039] In one specific embodiment, the thermosensitive hydrogel can be loaded onto fabric 100 or cotton fibers through coating finishing, impregnation treatment, or other methods.

[0040] In one specific embodiment, the thermosensitive hydrogel may be distributed in at least one of the gaps between cotton fibers, on the surface, and inside.

[0041] In one specific embodiment, the thermosensitive hydrogel swells at temperatures ≤32°C and shrinks at temperatures >32°C. It should be noted that the thermosensitive hydrogel regulates its expansion or contraction through temperature changes, thereby modulating the breathability and moisture absorption of fabrics. Simultaneously, it forms a dynamically balanced hydrophilic-hydrophobic surface with a temperature-sensitive response, releasing moisturizing factors when the skin is dry and forming a breathable barrier when moist, thus regulating the microenvironment.

[0042] In one specific embodiment, the thermosensitive hydrogel is an N-isopropylacrylamide copolymer.

[0043] In one specific embodiment, the thermosensitive hydrogel can be a microcapsule structure. That is, the thermosensitive hydrogel can be encapsulated within microcapsules.

[0044] In one specific embodiment, the cotton fabric 100 may also be loaded with an antibacterial agent. This further enables the cotton fabric 100 to possess antibacterial properties.

[0045] In one specific embodiment, the antibacterial agent may be distributed in at least one of the gaps between cotton fibers, on the surface, and inside.

[0046] In one specific embodiment, the antibacterial agent can be applied to fabric 100 or cotton fibers through coating finishing, printing, impregnation treatment, etc.

[0047] In one specific embodiment, the antibacterial agent can be a microcapsule structure. That is, the antibacterial agent can be encapsulated in microcapsules. This helps to avoid performance degradation caused by direct contact between the hydrogel and the fiber.

[0048] In one specific embodiment, the antibacterial agent may be AgNPs.

[0049] In one specific embodiment, the weight of pure cotton fabric 100 can be 40-300 g / m². 2 For example, 100g of pure cotton fabric can have a weight of 40g / m². 2 60g / m 2 80g / m 2 100g / m 2 120g / m 2 150g / m 2 180g / m 2 200g / m 2 250g / m2 Or 300g / m 2 .

[0050] In one specific embodiment, the thickness of the inner layer 10 can be 0.05 mm to 1 mm. For example, the thickness of the inner layer 10 can be 0.05 mm, 0.1 mm, 0.25 mm, 0.5 mm, 0.75 mm or 1 mm.

[0051] In one specific embodiment, the thickness of the outer layer 20 can be 0.05 mm to 1 mm. For example, the thickness of the outer layer 20 can be 0.05 mm, 0.1 mm, 0.25 mm, 0.5 mm, 0.75 mm or 1 mm.

[0052] The above description, in conjunction with specific embodiments, provides a further detailed explanation of this utility model. It should not be construed that the specific implementation of this utility model is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of this utility model, and all such modifications and substitutions should be considered within the protection scope of this utility model.
