Description

Technical Field

[0001] This utility model relates to the field of textile technology, specifically to a moisture-absorbing, heat-generating, and warm fleece-feel air-layer fabric. Background Technology

[0002] As people's demands for warmth, comfort, and aesthetics in winter clothing continue to rise, traditional thermal fabrics are no longer sufficient to meet market needs. Traditional thermal materials often rely on increasing fabric thickness or using natural insulating materials such as down and wool to achieve insulation, but this often results in bulky clothing, poor breathability, restricted movement, and difficulty in moisture wicking away, leading to a stuffy feeling. In recent years, the development of moisture-wicking and heat-generating fibers has provided a new direction for thermal fabrics. These fibers absorb human sweat and convert it into heat energy, achieving dynamic thermal regulation. However, fabrics with only moisture-wicking and heat-generating functions still have shortcomings in terms of long-term warmth retention. The heat generated is easily lost through air convection and conduction, and the lack of effective insulation structural design makes it difficult to maintain temperature continuously in cold environments.

[0003] Patent CN107503031A discloses a moisture-absorbing and heat-generating fabric, comprising an inner fabric and an outer fabric, woven from a first moisture-absorbing and heat-generating fiber blended with Porel and spandex fibers, and a second moisture-absorbing and heat-generating fiber blended with modal and acrylic fibers. The weaving method includes the following steps: (1) blending 85% Porel fiber and 15% spandex fiber by weight; (2) blending 70% modal fiber and 30% acrylic fiber by weight; (3) weaving the first moisture-absorbing and heat-generating fiber into the inner fabric using a 1-thread-6-hole yarn threading method; (4) the outer fabric is woven into a fish-scale structure by weaving the first and second moisture-absorbing and heat-generating fibers on a double-sided circular knitting machine; (5) the inner and outer fabrics are sewn together using a loop-sewing process. This invention utilizes blends of Porel and spandex fibers, and blends of modal and acrylic fibers, to weave inner and outer fabrics, achieving a moisture-absorbing and heat-generating effect. Although this patent has a certain moisture-absorbing and heat-generating effect, the heat generated is easily lost through air convection and conduction, resulting in poor heat preservation.

[0004] This application is submitted in order to solve the above-mentioned technical problems. Utility Model Content

[0005] The technical problem solved by this invention is that, in the prior art, the heat generated by moisture-absorbing and heat-generating fabrics is easily lost through air convection and conduction, resulting in poor heat preservation.

[0006] To address the aforementioned issues, this utility model discloses a moisture-absorbing, heat-generating, and warm fleece-like air-layer fabric, comprising a surface layer, an air layer, and an inner layer. The surface layer and the inner layer are woven from moisture-absorbing and heat-generating blended yarns, and are connected by a connecting yarn layer. A certain gap exists between corresponding surfaces of the surface layer and the inner layer, forming an air layer.

[0007] Furthermore, the moisture-absorbing and heat-generating blended yarn is formed by blending moisture-absorbing and heat-generating fibers with cellulose fibers.

[0008] Furthermore, the thickness of the moisture-absorbing and heat-generating blended yarn is 50S-30S.

[0009] Furthermore, the outer and inner layers are respectively formed by weaving moisture-absorbing and heat-generating blended yarn and spandex yarn.

[0010] Furthermore, the spandex filament has a thickness of 15D-40D.

[0011] Furthermore, an upper connecting wire layer is provided on the surface layer, a lower connecting wire layer is provided on the inner layer, and an intermediate wire layer is provided between the upper and lower connecting wire layers. The intermediate wire layer is coiled between the upper and lower connecting wire layers to connect the surface layer and the inner layer and form a hollow air layer.

[0012] Furthermore, the upper connecting filament layer, the lower connecting filament layer, and the middle filament layer are all polyester filaments.

[0013] Furthermore, the thickness of the upper and lower connecting filament layers is 30D-75D, and the thickness of the middle filament layer is 50D-100D.

[0014] Furthermore, the fabric pattern is arranged in a six-way cycle, in the following order from bottom to top: The first way's structure is, in sequence, needle cylinder float stitch, needle cylinder tuck stitch, needle plate tuck stitch, and needle plate float stitch; the second way's structure is, in sequence, needle cylinder tuck stitch, needle cylinder float stitch, and needle plate tuck stitch; the third way's structure is, in sequence, needle cylinder float stitch, needle plate small loop stitch, and needle plate small loop stitch; the fourth way's structure is, in sequence, needle cylinder float stitch, needle plate loop stitch, and needle plate loop stitch; the fifth way's structure is, in sequence, needle cylinder small loop stitch, needle cylinder small loop stitch, needle plate float stitch, and needle plate float stitch; the sixth way's structure is, in sequence, needle cylinder loop stitch, needle plate float stitch, and needle plate float stitch.

[0015] Furthermore, the sixth thread is woven into the outer layer, the fifth thread into the upper connecting thread layer, the fourth thread into the inner layer, the third thread into the lower connecting thread layer, and the first and second threads into the hollow layer.

[0016] The moisture-absorbing, heat-generating, and warm fleece-like air-layer fabric described in this application has the following advantages:

[0017] First, through the setting of moisture-absorbing and heat-generating fibers in the surface and inner layers, it can absorb the sweat produced by the human body and efficiently convert it into heat energy, achieving rapid heating and continuous warmth.

[0018] Secondly, by setting an air layer between the outer and inner layers, a three-dimensional heat-insulating structure is formed, which effectively stores still air between the outer and inner layers, significantly improving the heat-insulating performance of the fabric while increasing the number of fabric layers and fluffiness.

[0019] Third, the napping process in the finishing stage creates short and dense nap on the front of the fabric, giving the fabric a delicate velvety feel. This not only increases the fabric's warmth but also enhances its comfort and aesthetics. Attached Figure Description

[0020] Figure 1 This is a cross-sectional structural diagram of the moisture-absorbing, heat-generating, warm, and plush-feel air layer fabric described in this embodiment of the present invention. Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the described embodiments are only some, not all, of the embodiments of this utility model. The specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0022] The following describes in detail, with reference to the accompanying drawings, a moisture-absorbing, heat-generating, warm, plush-feel air layer fabric according to an embodiment of the present invention.

[0023] Example 1

[0024] A moisture-wicking, heat-generating, and warm fleece-like air-layer fabric, such as Figure 1 As shown, it includes a surface layer, an air layer, and an inner layer. The surface layer and the inner layer are woven from moisture-absorbing and heat-generating blended yarns, and are connected by a connecting filament layer. There is a certain gap between the corresponding surfaces of the surface layer and the inner layer to form an air layer.

[0025] In this application, the outer and inner layers are relatively independent and connected by a connecting yarn layer, forming a stable three-dimensional air interlayer. The sealed air layer formed therein can effectively store a large amount of still air. Due to the extremely low thermal conductivity of still air, this structure constitutes a highly efficient thermal barrier, which can significantly block the loss of heat generated when the moisture-absorbing and heat-generating blended yarn absorbs human sweat to the external environment. Compared with the traditional method of achieving warmth by thickening wadding or filling, this structure achieves the same or even better heat retention rate while greatly reducing the fabric weight and thickness, successfully solving the technical contradiction of "lightweight" and "warm" in winter clothing, and giving the fabric excellent characteristics of lightweight and high warmth retention. After testing, the heat retention rate of the fabric provided in this example is ≥30%, which is much higher than the heat retention rate of moisture-absorbing and heat-generating fabrics on the market. In this application, the moisture-absorbing and heat-generating fabric generates heat, and the air layer provides insulation, thereby achieving passive heat generation and active heat retention of the fabric, significantly improving the overall heat retention performance of the fabric. Specifically, the number of layers, loft, and specific weave structure of each layer in the fabric can be adjusted according to actual warmth requirements and garment style, which will not be elaborated here.

[0026] As one possible example, the moisture-absorbing and heat-generating blended yarn is formed by blending moisture-absorbing and heat-generating fibers with cellulose fibers. This yarn design cleverly combines the advantages of both fibers. The moisture-absorbing and heat-generating fibers (such as acrylic or polyester) are responsible for the core moisture-absorbing and heat-generating function. They rapidly absorb water vapor emitted by the human body and convert the kinetic energy of water molecules into heat energy, achieving active temperature rise. The average temperature rise within 30 minutes is ≥3.0℃, and the maximum temperature rise is ≥4.0℃. Meanwhile, cellulose fibers such as viscose, modal, lyocell, or cotton, due to their excellent skin-friendliness, moisture absorption, and soft touch, form the basis for the fabric's contact with the skin, ensuring wearing comfort. The moisture-absorbing and heat-generating blended yarn is formed through the spinning process of ordinary short-fiber yarn; specific details can be found in existing technologies and will not be elaborated here. By employing conventional short-fiber spinning processes (such as ring spinning or rotor spinning) for blending, the production of moisture-absorbing and heat-generating blended yarns can be seamlessly integrated into existing mature spinning systems. This ensures process stability, yarn quality uniformity, and the feasibility of large-scale production, thus lowering the industrialization threshold. It should be noted that, while maintaining moisture-absorbing and heat-generating properties, one or more of the moisture-absorbing and heat-generating fibers, such as acrylic, polyester, ecstasy, and heat-reducing yarn, can be selected according to specific needs.

[0027] Specifically, the mass ratio of moisture-absorbing and heat-generating fibers to cellulose fibers in the moisture-absorbing and heat-generating blended yarn is between 20 / 80 and 40 / 60. When the content of moisture-absorbing and heat-generating fibers reaches more than 20%, the fabric can exhibit significant moisture-absorbing and heat-generating properties; when it is increased to 40%, the heat-generating efficiency is even stronger. Maintaining the cellulose fiber content at a high level of 60%-80% ensures that the main body of the fabric has excellent moisture management capabilities and a skin-friendly texture, avoiding the stuffiness that may be caused by excessive synthetic fiber content. On the other hand, using low-cost cellulose fibers as the main body also effectively controls the raw material cost of functional fabrics, making the product more competitive in the market.

[0028] Optionally, the moisture-absorbing and heat-generating blended yarn has a fineness of 50S-30S. 50S yarn is relatively fine, resulting in fabrics with a delicate surface and lightweight texture, suitable for high-end garments requiring a higher level of fashion and fit. 30S yarn is relatively coarser, producing thicker, more voluminous fabrics. This allows the fabric to contain more still air and provides a richer yarn base for the subsequent crucial finishing process of napping, facilitating the formation of dense, uniform, and non-shedding short fibers, achieving a velvety feel. Overall, the moisture-absorbing and heat-generating blended yarn used in this application is relatively coarse, making it easier for the napping rollers to grasp and break it during the subsequent napping process, resulting in a fabric that more easily forms dense, uniform, and strong short fibers.

[0029] As an example of this utility model, the outer layer and the inner layer are respectively woven from moisture-absorbing and heat-generating blended yarn and spandex yarn. In this example, the yarn combination of the outer layer and the inner layer is consistent, and the moisture-absorbing and heat-generating blended yarn serves as the main functional yarn. The inclusion of spandex yarn in the main functional yarns of both the outer and inner layers provides the fabric with appropriate lateral and longitudinal tensile recovery. This elasticity ensures that the fabric conforms to the curves of the human body, adapts to deformation during activity, and provides a sense of freedom, greatly improving the dynamic comfort of wearing the garment.

[0030] The spandex yarn has a thickness of 15D-40D. When the spandex yarn is within this range, it can effectively prevent excessive stretching and compression of the hollow air layer due to excessive elasticity, thereby maintaining the stability of the three-dimensional thermal insulation structure while providing comfortable elasticity, and ensuring the thermal insulation effect of the fabric.

[0031] Optionally, an upper connecting yarn layer is provided on the surface, a lower connecting yarn layer is provided on the inner layer, and an intermediate yarn layer is provided between the upper and lower connecting yarn layers. The intermediate yarn layer is looped between the upper and lower connecting yarn layers to connect the surface and inner layers and form a hollow air layer. The upper and lower connecting yarn layers are firmly bonded to the surface and inner layers respectively, ensuring that the multi-layer structure does not easily delaminate during use and washing. The intermediate yarn layer connects the upper and lower connecting yarn layers through a loop, providing the necessary stiffness and support to the intermediate layer, enabling it to effectively resist external pressure, prevent the air layer from collapsing, and maintain a fluffy hollow state over a long period. Through the above structure, the three-dimensional heat-insulating structure of the fabric not only performs excellently in the initial manufacturing process but also maintains its heat-insulating performance after multiple wears and washes, significantly improving the durability of the garment.

[0032] Specifically, the upper connecting layer, lower connecting layer, and middle layer are all made of polyester filament. These polyester filaments are characterized by high strength, high modulus, wrinkle resistance, and dimensional stability. The connecting layer structure made of polyester filament is stable and fluffy, ensuring both moisture absorption, heat generation, and insulation, while also guaranteeing the durability of the garment.

[0033] Optionally, the upper and lower connecting yarn layers have a denier of 30D-75D, and the middle yarn layer has a denier of 50D-100D. The upper and lower connecting yarn layers provide a certain strength and toughness to maintain the stability of the connection structure, while the middle yarn layer, with its relatively high denier, provides the necessary stiffness and support, enabling the fabric to effectively resist external pressure and prevent the air layer from being flattened, thereby ensuring the long-lasting fluffiness of the insulating air layer.

[0034] Specifically, the fabric pattern is arranged in a six-way cycle, in the following order from bottom to top: The first way's structure is, in sequence, needle tube float stitch, needle tube tuck stitch, needle plate tuck stitch, and needle plate float stitch; the second way's structure is, in sequence, needle tube tuck stitch, needle tube float stitch, needle plate float stitch, and needle plate tuck stitch; the third way's structure is, in sequence, needle tube float stitch, needle plate small loop stitch, and needle plate small loop stitch; the fourth way's structure is, in sequence, needle tube float stitch, needle plate loop stitch, and needle plate loop stitch; the fifth way's structure is, in sequence, needle tube small loop stitch, needle tube small loop stitch, needle plate float stitch, and needle plate float stitch; the sixth way's structure is, in sequence, needle tube loop stitch, needle plate float stitch, and needle plate float stitch. Through the above settings, the fabric can be produced in one piece, so that the weaving structure (air layer) and functional materials (moisture-absorbing and heat-generating blended yarn) are formed in one process, so that the three-dimensional heat-insulating function of the fabric is "woven" into it from the source of production, thereby achieving structural stability and functional durability that are difficult for ordinary composite fabrics to match.

[0035] In this process, the sixth weave forms the outer layer, the fifth weave forms the upper connecting layer, the fourth weave forms the inner layer, the third weave forms the lower connecting layer, and the first and second weaves form the hollow layer. The jacquard structure of the fabric formed by this seven-layer air-layer weaving method allows for one-time weaving, resulting in high production efficiency, strong structural integrity, precise and controllable weaving process, and uniform and stable air-layer thickness in the final fabric. The specific processes and parameters can be determined based on the specific equipment and technological conditions. Furthermore, during production, each step can be optimized and improved according to actual production conditions to enhance production efficiency and product quality; these modifications are not limited here.

[0036] The fabric provided in this example is mainly used in the manufacture of winter clothing. It aims to provide a lightweight, fashionable fabric with excellent warmth retention that combines moisture absorption and heat generation with continuous heat retention, meeting consumers' multiple needs for warmth, aesthetics, and comfort in the cold season.

[0037] Example 2

[0038] A method for preparing a fabric, the method being used to prepare the fabric described in Example 1 above, the preparation method comprising the steps of:

[0039] S1, Yarn preparation; using the yarn from Example 1;

[0040] S2, Fabric weaving; Weaving is performed according to the weaving method described in Example 1;

[0041] S3, dyeing and finishing process.

[0042] Furthermore, step S1, the yarn preparation process includes: selecting moisture-absorbing and heat-generating blended yarn, spandex yarn, and polyester filament as yarns for weaving.

[0043] Preferably, in step S1, a 50S-30S moisture-absorbing and heat-generating blended yarn is selected as the main functional yarn, and 15D-40D spandex yarn, 30D-75D and 50D-100D polyester filament are selected.

[0044] In step S2, a double-sided circular knitting machine is used to weave the fabric, and the weaving process is as described in Example 1.

[0045] Furthermore, step S3, the dyeing and finishing process, includes the following steps:

[0046] S31, staining;

[0047] S32, dehydration and drying;

[0048] S33, brushed;

[0049] S34, Re-fixed.

[0050] As an example of this utility model, step S31 includes:

[0051] S311, Immerse the greige fabric in the dye vat with a liquor ratio of 1:10;

[0052] S312: Adjust the pH of the dyeing solution to 4.5-5.0 by adding glacial acetic acid, add 2-3% disperse dye (owf) and 1.0-2.0 g / L high-temperature leveling agent, raise the temperature from room temperature to 128-130℃ at a rate of 1.0-1.5℃ / min, keep it at this temperature for 40-60 minutes, then lower the temperature to 75-80℃ at a rate of 1.5-2.0℃ / min and drain the dyeing solution. Perform hot water washing, soap washing (soaping agent 0.8-1.2 g / L), and washing with clean water until neutral.

[0053] S313, Refill the dyeing vat with water, and re-immerse the fabric dyed in S312 into the dyeing vat, with a liquor ratio of 1:10;

[0054] For S314, heat to 75-80℃, add 1-2% (owf) of reactive dye and 40-80g / L of sodium sulfate, keep warm for 15-20 minutes, then add 10-20g / L of fixing agent soda ash in two batches, and keep warm at 75-80℃ for 50-60 minutes. Drain the dye solution, then wash with hot water, neutralize with acid, soap, and wash with water until the water is clear.

[0055] Through the above operations, different materials in the fabric are dyed separately, ensuring that different types of yarn can achieve the best dyeing effect and guaranteeing color fastness. Some steps, such as hot water washing, acid neutralization, soap washing, and water washing, can refer to existing technologies and will not be described in detail here.

[0056] As an example of this utility model, step S32 includes:

[0057] Step S321: The dyed fabric from step S31 is centrifuged at low speed to dehydrate, with a rotation speed of 600-800 rppm. The target moisture content after dehydration is 60%-70%.

[0058] Step S322: Dry the dehydrated fabric at 80-110℃ for 30-50 minutes to achieve a target moisture content of 6%-9%.

[0059] Preferably, step S322 includes:

[0060] Step S3221, initial stage: dry at 80-90℃ for 10-15 minutes; use a lower temperature for initial drying to avoid the surface drying too quickly and forming a hard shell that would hinder the escape of internal moisture;

[0061] Step S3222, main drying stage, drying at 100-110℃ for 15-25 minutes; higher temperature is used to accelerate the drying process;

[0062] Step S3223, final drying stage, drying at 90-100℃ for 5-10 minutes; final drying at a relatively mild temperature;

[0063] Step S3224, Cooling: Lay the fabric flat or hang it in a relaxed state to cool to room temperature.

[0064] By following the steps above, the fabric drying process can be effectively ensured to proceed efficiently.

[0065] As one example, step S33 includes: performing a napping treatment on the front side of the fabric (i.e., the fabric material) on a napping machine, wherein the napping roller rotates at 800-1200 rpm and the fabric feed speed is 16-20 m / min, so that the warp and weft threads of the fabric produce short and dense uniform nap with a nap length of 0.3-0.8 mm.

[0066] Specifically, step S34 includes: re-setting the fabric after brushing in step S33 at 130℃-150℃, with a machine speed of 18-25m / min and an overfeed of 5%-15%, to obtain the final moisture-absorbing, heat-generating, warm, and plush-feel air layer fabric. Preferably, the re-setting temperature is 140℃, the machine speed is 22m / min, and the overfeed is 10%.

[0067] In summary, it is easy to conclude that the fabric provided in this embodiment has the following advantages:

[0068] First, through the setting of moisture-absorbing and heat-generating fibers in the surface and inner layers, it can absorb the sweat produced by the human body and efficiently convert it into heat energy, achieving rapid heating and continuous warmth.

[0069] Secondly, by setting an air layer between the outer and inner layers, a three-dimensional heat-insulating structure is formed, which effectively stores still air between the outer and inner layers, significantly improving the heat-insulating performance of the fabric while increasing the number of fabric layers and fluffiness.

[0070] Third, the napping process in the finishing stage creates short and dense nap on the front of the fabric, giving the fabric a delicate velvety feel. This not only increases the fabric's warmth but also enhances its comfort and aesthetics.
