Description

Technical Field

[0001] This utility model relates to the field of textile fabrics, specifically a moisture-wicking composite fabric. Background Technology

[0002] With the rapid development of the social economy and the significant improvement of people's living standards, consumers are no longer satisfied with the basic function of clothing—covering the body and keeping warm—but are increasingly focusing on the performance of clothing fabrics and the wearing experience. Consumers, in particular, have raised higher requirements for wearing comfort. However, commonly available clothing fabrics on the market often have certain limitations in terms of functionality, especially in terms of breathability, heat dissipation, and moisture-wicking properties. Specifically, these limitations are reflected in the following aspects:

[0003] 1. Insufficient breathability. Poor heat dissipation is a common problem with traditional fabrics. These fabrics have relatively tight fiber or weave structures, resulting in poor air circulation. This makes it difficult for heat and moisture generated by the body to dissipate effectively, causing them to accumulate inside the garment and creating a stuffy feeling. This stuffiness is especially noticeable in hot environments or during exercise, severely impacting wearing comfort.

[0004] 2. Lack of effective sweat-wicking function. During physical activity, the skin secretes sweat to regulate body temperature. However, traditional fabrics have limited moisture-wicking properties, or the moisture absorbed is difficult to evaporate quickly, causing sweat to remain between the skin and clothing. This makes clothes sticky and uncomfortable, resulting in a damp and sticky feeling. Wearing sweaty clothes for extended periods not only provides a poor wearing experience but can also easily lead to skin problems.

[0005] In summary, traditional clothing fabrics have shortcomings in breathability, heat dissipation, and moisture wicking. Therefore, how to overcome the deficiencies of existing technologies and develop a new type of fabric with good breathability, excellent heat dissipation, and efficient moisture wicking to improve the comfort of clothing and meet people's growing demand for functional clothing has become an urgent technical problem to be solved in this field. Utility Model Content

[0006] The purpose of this invention is to overcome the shortcomings of traditional clothing fabrics in the prior art, such as poor breathability, poor heat dissipation, and insufficient moisture absorption and wicking function, and to provide a novel moisture-wicking composite fabric. This fabric can effectively absorb human sweat and quickly wick it away, while maintaining good breathability and heat dissipation, thereby significantly improving wearing comfort and meeting consumers' growing demand for functional clothing. The technical solution adopted in this invention is as follows.

[0007] A moisture-wicking composite fabric, comprising a moisture-wicking layer and a breathable layer;

[0008] The moisture-absorbing layer is located on the inner side of the composite fabric. The side of the moisture-absorbing layer closest to human skin is the skin-contact surface. Multiple first moisture-permeable channels extending vertically are evenly distributed on the skin-contact surface. The moisture-absorbing layer is woven from hollow yarns. A second moisture-permeable channel is provided in the center of the hollow yarns. The second moisture-permeable channel is a cavity structure formed in the center of the hollow yarns.

[0009] The moisture-absorbing layer is connected to the breathable layer on the side opposite to the skin-contacting surface through a connecting structure. The breathable layer is located on the outside of the composite fabric and has breathable mesh holes evenly distributed on it.

[0010] The first moisture-permeable channel is formed by a groove structure on the skin-contact surface, and the cross-section of the first moisture-permeable channel is inverted V-shaped.

[0011] The breathable layer has a gauze weave structure, and the cross-section of the breathable mesh is hexagonal.

[0012] In some embodiments, the width of the first moisture-permeable channel is 0.5-2.0 mm, the depth is 0.2-0.8 mm, and the spacing between two adjacent first moisture-permeable channels is 1-5 mm.

[0013] In some embodiments, the yarn count of the hollow yarn is 50D-75D.

[0014] In some embodiments, the inner diameter of the second moisture-permeable channel is 0.02-0.1 mm, and the ratio of the inner diameter of the second moisture-permeable channel to the outer diameter of the hollow yarn is 10%-60%.

[0018] The beneficial effects of this utility model are as follows:

[0019] This invention provides a moisture-wicking composite fabric with highly efficient moisture absorption and wicking properties, keeping the skin dry and comfortable. The moisture-wicking layer is made of hollow yarn, and the hydrophilic modified fibers have excellent moisture absorption properties while forming a second moisture-permeable channel in the center, which can quickly absorb sweat from the skin surface. The skin-contact side is provided with a first moisture-permeable channel, which further enhances the capillary action on the fabric surface, guiding sweat to spread and transfer rapidly. The outer breathable layer adopts a woven leno structure and a breathable mesh design, which can promote air circulation and accelerate moisture evaporation, thereby effectively transferring sweat from the skin surface to the outer layer of the fabric and dissipating it, keeping the skin dry and comfortable.

[0029] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the scope of this patent. To better illustrate this embodiment, some parts in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product.

[0030] It will be understood by those skilled in the art that certain well-known structures and their descriptions may be omitted in the accompanying drawings. The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0031] As attached Figure 1-3The illustrated moisture-wicking composite fabric includes a moisture-wicking layer 1 and a breathable layer 2. The moisture-wicking layer 1 is located on the inner side of the composite fabric, with the side of the moisture-wicking layer 1 closest to the human skin being the skin-contact surface 11. Multiple first moisture-permeable channels 12 extending vertically are evenly distributed on the skin-contact surface 11. The moisture-wicking layer 1 is woven from hollow yarns 13, with a second moisture-permeable channel 131 located at the center of each hollow yarn 13. The second moisture-permeable channel 131 is a cavity structure formed at the center of the hollow yarn 13. The breathable layer 2 is connected to the side of the moisture-wicking layer 1 away from the skin-contact surface 11 via a connecting structure. The breathable layer 2 is located on the outer side of the composite fabric and has evenly distributed breathable mesh holes 21. The first moisture-permeable channels 12 are formed by groove structures on the skin-contact surface 11, and the cross-section of the first moisture-permeable channel 12 is an inverted V-shape. The breathable layer 2 has a leno weave structure, and the cross-section of the breathable mesh holes 21 is hexagonal.

[0032] In some embodiments, the width of the first moisture-permeable channel 12 is 0.5-2.0 mm, the depth is 0.2-0.8 mm, and the spacing between two adjacent first moisture-permeable channels 12 is 1-5 mm.

[0033] In some embodiments, the yarn count of the hollow yarn 13 is 50D-75D.

[0034] In some embodiments, the inner diameter of the second moisture-permeable channel 131 is 0.02-0.1 mm, and the ratio of the inner diameter of the second moisture-permeable channel 131 to the outer diameter of the hollow yarn 13 is 10%-60%.

[0035] In some embodiments, the hollow yarn 13 is 50D hydrophilic modified polyester hollow yarn 13.

[0036] In some embodiments, the side length of the breathable mesh 21 is 0.5-3.0 mm, and the density of the breathable mesh 21 is 5-20 per square centimeter.

[0037] When sweat is produced on the surface of human skin, it first comes into contact with the skin-contacting surface 11 of the moisture-wicking layer 1. The skin-contacting surface 11 has evenly distributed first moisture-wicking channels 12. The inclined sidewall structure of the first moisture-wicking channels 12 makes it easier for sweat to be absorbed and quickly rise and diffuse along the first moisture-wicking channels 12. The inclined sidewall of the first moisture-wicking channels 12 changes the geometry of the droplet contact line and optimizes the contact angle and meniscus radius of curvature, thereby maximizing capillary pressure. The vertically extending first moisture-wicking channels 12 provide a pre-defined channel for the flow of sweat. Under the guidance of capillary action and the first moisture-wicking channels 12, sweat flows more quickly along the direction of the first moisture-wicking channels 12, avoiding accumulation or disordered diffusion on the skin surface and improving moisture-wicking efficiency. After the sweat is initially collected and guided by the first moisture-wicking channels 12, it quickly comes into contact with the hollow yarn 13 that constitutes the moisture-wicking layer 1. The hollow structure at the center of the hollow yarn 13 forms a second moisture-wicking channel 131 inside the yarn. The fiber material itself is hygroscopic. In addition, the humidity difference and pressure difference inside and outside the second moisture permeability channel 131 create a siphon effect, which allows the second moisture permeability channel 131 to actively draw moisture from the yarn fibers into the second moisture permeability channel 131 and transport it longitudinally along the hollow yarn 13.

[0038] The second moisture-permeable channel 131 increases the internal space of the hollow yarn 13, effectively increasing its water storage capacity. The hollow yarn 13 can hold more moisture without becoming oversaturated, thus maintaining both its absorbency and the fabric's breathability. When the absorbent layer 1 absorbs sweat, its moisture concentration increases relatively, while the breathable layer 2, being in direct contact with the outside air, has a relatively lower moisture concentration. This moisture concentration gradient drives moisture transfer from the inner layer to the outer layer. The evenly distributed breathable mesh 21 on the breathable layer 2 further increases the fabric's porosity, providing direct airflow channels. Air can freely pass through the breathable mesh 21, allowing the fabric to dry quickly.

[0039] Furthermore, the shape of the first moisture-wicking channel 12 reduces sweat backflow to some extent. When the outer layer does not wick away sweat well or the ambient humidity is high, sweat may seep back from the outer layer of the fabric to the inner layer. The pointed structure of the first moisture-wicking channel 12 provides a certain degree of obstruction, slowing down the speed and extent of sweat backflow and keeping the skin-contact surface 11 relatively dry.

[0040] Example 1:

[0041] The moisture-absorbing layer 1 uses 50D hydrophilic modified polyester hollow yarn 13, which has a circular cross-section with a central cavity inner diameter of approximately 0.05mm. The ratio of the cavity inner diameter to the yarn outer diameter is approximately 30%. The breathable layer 2 uses 75D polyester filament with a conventional circular cross-section.

[0042] The moisture-wicking layer 1 is woven on a weft knitting machine using a weft knitting process. A double-sided weft knitting machine is used, employing a structure combining tuck stitches and plain knit stitches on the reverse needle bed. Specific weave parameters are: plain knit stitches every 4 loops, followed by tuck stitches every 1 loop, arranged in a cyclical pattern. The tuck stitches use single-needle tuck stitches, with a sinker depth of 0.5mm and a starting height of 1.0mm for the loop formation triangle. By adjusting the tuck stitch parameters, the fabric's skin-contact surface 11 forms a first moisture-permeable channel 12 with a width of approximately 1.0mm, a depth of approximately 0.5mm, and a cross-section approximately inverted V-shaped, with an adjacent channel spacing of approximately 3mm.

[0043] The breathable layer 2 is woven on a shuttle loom equipped with a heddle mechanism. A leno weave is used, with both warp and weft yarns made of 75D polyester filament. The warp and weft insertion parameters of the leno weave are adjusted to form approximately hexagonal breathable mesh 21, with a mesh side length of 1.0 mm and a mesh density of 10 meshes per square centimeter.

[0044] Finally, the inner weft-knitted moisture-absorbing layer 1 and the outer woven gauze breathable layer 2 are laminated using a dot-matrix hot-pressing process. A breathable hot melt adhesive is selected and evenly distributed on the back of the inner moisture-absorbing layer 1 using a dot-matrix coating method. Then, the outer woven breathable layer 2 is placed on top of the inner layer. The lamination is then performed using a hot press at appropriate temperature and pressure, ensuring the two layers are firmly bonded at the dotted points to form an integrated double-layer composite fabric. The density of the dot-matrix hot-pressing bonding points is controlled at approximately 5-8 points per square centimeter.
