Description

Technical Field

[0001] This utility model relates to the field of quick-drying fabric technology, specifically to a quick-drying and breathable fabric and garment. Background Technology

[0002] Traditional natural fibers (such as cotton) have good hydrophilicity and moisture absorption, but once they absorb sweat, the moisture is difficult to evaporate, resulting in slow drying and causing wearers to experience a damp, cold, and sticky discomfort, and even the risk of hypothermia in certain environments. While conventional synthetic fibers (such as polyester) dry quickly, their inherent hydrophobicity and poor moisture absorption cause sweat to remain on the skin's surface for extended periods, leading to a stuffy feeling. To address these issues, current technologies have shifted towards functional finishing and multi-layered fabric composites. A common practice is to add hydrophilic finishing agents to hydrophobic synthetic fiber fabrics to improve their moisture absorption. However, this hydrophilicity is usually not washable, and its function significantly diminishes or even disappears with repeated use. Therefore, current fabrics do not fully meet user needs in terms of quick-drying and breathability. Utility Model Content

[0003] The purpose of this utility model is to overcome the above-mentioned defects or problems in the background art and provide a quick-drying and breathable fabric and garment, which has good quick-drying and breathable properties.

[0008] Technical Solution 4 based on Technical Solution 3: The diagonal length of the through hole in the moisture-absorbing layer is 0.5-1.0mm, and the diagonal length of the through hole in the quick-drying layer is 1.5-2.0mm.

[0009] Technical Solution 5 based on Technical Solution 3: The apex position of the through hole in the moisture-absorbing layer, moisture-permeable layer and quick-drying layer is fixed by a reinforcing yarn that runs through the fabric body along the thickness direction; the reinforcing yarn is an elastic yarn.

[0012] Technical solution eight based on technical solution one: the polyester yarns used in the moisture-absorbing layer and quick-drying layer have deniers of 40D / 70F-50D / 70F and 75D / 34F-150D / 68F, respectively.

[0013] Technical Solution Nine based on Technical Solution One: The core material of the core-spun fiber is polytetrafluoroethylene filament, and its sheath is polyester staple fiber.

[0014] In addition, this utility model also provides technical solution ten: a quick-drying and breathable garment, which is made of quick-drying and breathable fabric as described in any one of technical solutions one to nine.

[0015] As can be seen from the above description of this utility model, compared with the prior art, this utility model has the following beneficial effects:

[0016] Technical solution one provides a quick-drying and breathable fabric. The fabric body includes a moisture-absorbing layer, a moisture-permeable layer and a quick-drying layer stacked in sequence. Through the cooperation of the three, efficient and unidirectional moisture transfer and quick-drying of the fabric are achieved.

[0017] First, when the human body sweats, sweat accumulates on the skin's surface, creating a damp, cold, and sticky discomfort. The moisture-wicking layer, in direct contact with the skin, features a tightly arranged structure of raised and recessed sections formed by yarn weaving. The raised sections create point-like contact with the skin, reducing the actual contact area between the fabric and the skin, thus minimizing the sticky feeling after the fabric becomes wet. Simultaneously, the recessed sections between adjacent raised sections utilize capillary action to actively and quickly absorb liquid sweat from the skin's surface into the fabric's interior. This structure not only increases the surface area in contact with sweat, accelerating the moisture absorption process, but also provides the initial channel and driving force for sweat to migrate to the outer layer. Furthermore, the moisture-wicking layer in direct contact with the skin utilizes its dense capillary network formed by fine denier polyester fibers to generate a capillary effect, rapidly absorbing liquid sweat from the skin's surface into the fabric's interior. Therefore, the macroscopic structure and the weaving structure of the moisture-wicking layer work synergistically to further improve its moisture absorption efficiency.

[0018] Subsequently, the middle breathable layer plays a crucial role in unidirectional moisture permeability. This layer uses core-spun yarn, whose hydrophilic outer layer (water contact angle 10-50 degrees) actively draws moisture from the absorbent layer. Meanwhile, its hydrophobic core material (water contact angle 100-140 degrees) forms a physical barrier, preventing moisture from seeping back from the breathable layer to the absorbent layer by utilizing the difference in surface energy. This design ensures unidirectional sweat conduction, solving the problem of moisture backflow and re-wetting of the skin under pressure, a common issue with traditional fabrics. Moisture transferred from the breathable layer enters the quick-drying layer, where the larger pores between the coarse denier polyester fibers facilitate rapid diffusion and spread. More importantly, the irregularly shaped polyester fibers used in this layer have a much larger specific surface area than round cross-section fibers, significantly increasing the contact area between moisture and air. Moisture spreads rapidly along the fiber direction in the grooves on the surface of the irregularly shaped fiber, forming a thinner water film, which significantly improves the evaporation rate and achieves rapid drying.

[0019] Furthermore, the tapered channels that run through the three layers and gradually widen from the inside out provide an additional, efficient path for moisture transfer. This channel structure, which is smaller inside and larger outside, helps guide the high-humidity air inside to diffuse directionally into the low-humidity environment outside, further improving the overall breathability of the fabric and preventing stuffiness.

[0020] In summary, the quick-drying and breathable fabric provided by this technical solution integrates a moisture-absorbing layer with a specific physical structure, a breathable layer with unidirectional moisture permeability, and a quick-drying layer with high evaporation capacity into a single weave, supplemented by through-hole conical units. While ensuring the softness and comfort of the fabric itself, it constructs a highly efficient unidirectional moisture permeability system. This system can quickly absorb sweat from the skin surface, forcibly conduct it unidirectionally to the outer layer of the fabric, and finally evaporate it quickly, thus providing the wearer with a lasting dry and comfortable experience.

[0021] Technical Solution Two further clarifies the implementation method of the conical channel, which is formed by sequentially stacking through-holes of varying sizes on the moisture-absorbing layer, the moisture-permeable layer, and the quick-drying layer. This structure has clear manufacturing advantages and functional stability. By setting through-holes of specific sizes in each layer, rather than performing subsequent conical hole-enlarging processing on the entire fabric, the manufacturing process is simplified, and production efficiency and yield are improved. At the same time, since the through-holes in each layer are of uniform size, the structure of the pore units can remain relatively stable when the fabric is stretched or deformed, thereby ensuring that the conical geometry with gradually increasing openings from the inside to the outside is reliably maintained. This provides a continuous and stable physical channel for the directional diffusion of moisture from the inside to the outside, ensuring the uniformity and durability of the overall moisture permeability of the fabric.

[0022] In technical solution three, the shape of the perforated unit on the fabric plane is defined as a regular hexagon. The regular hexagonal structure itself has excellent mechanical stability and can evenly distribute the external force received throughout the entire structural network. This makes the fabric less prone to local deformation or damage caused by stress concentration while maintaining a high porosity, thus enhancing the fabric's durability and tear resistance.

[0023] Technical Solution Four defines the size range of the through-holes in the moisture-wicking layer and the quick-drying layer. The smaller pore size of 0.5-1.0 mm in the moisture-wicking layer ensures that the inner layer in contact with the skin has a sufficiently large solid fabric area to maintain the core function of the moisture-wicking layer relying on the capillary effect of the yarn, avoiding sacrificing moisture-wicking capacity due to excessively large pores. The larger pore size of 1.5-2.0 mm in the quick-drying layer provides a smooth diffusion outlet for the sweat vapor that has already been converted into gaseous form, accelerating its exchange with the outside air.

[0024] In technical solution five, an elastic reinforcing yarn is introduced that runs along the fabric thickness direction to fix the vertices of the regular hexagonal through-holes. The reinforcing yarn effectively prevents relative slippage between layers during washing, wearing, and stretching, thus ensuring that the conical channel formed by the aligned through-holes of different layers does not misalign or deform. Using elastic yarn as the reinforcing yarn further endows the fabric with excellent resilience. When the fabric is stretched, the elastic yarn can elongate accordingly; when the external force is removed, it can pull the hole unit structure back to its initial regular shape, allowing the fabric's breathability and shape stability to be maintained over a long period.

[0025] In technical solution six, a specific proportion of spandex twisted yarn is added to the moisture-absorbing layer. The addition of spandex gives the moisture-absorbing layer, which comes into direct contact with the skin, better elasticity and stretch. This ensures that the fabric closely conforms to the contours of the human skin, maintaining its shape even during vigorous movement. This ensures that the moisture-absorbing structure, composed of raised and recessed sections, remains effectively applied to the skin surface, achieving efficient sweat absorption. Furthermore, because the moisture-absorbing layer has a different elasticity than the breathable and quick-drying layers, it allows for the removal of dander and other debris adhering to its inner surface through subtle vibrations, preventing blockage of the capillary channels.

[0026] Technical Solution Seven specifically specifies that the cross-section of the polyester fibers in the quick-drying layer is Y-shaped or propeller-shaped. The Y-shaped or propeller-shaped cross-section not only significantly increases the specific surface area of ​​the fibers, providing a broader platform for moisture evaporation, but its unique groove structure also forms multiple capillary channels between the fiber surfaces. When liquid water is conducted to the quick-drying layer, these capillary channels utilize capillary forces to rapidly transport and spread the water along the fiber axis, quickly transforming concentrated water droplets into a uniform thin water film. The combined effect of moisture spreading and increased surface area greatly enhances the evaporation rate, thereby optimizing the quick-drying effect of the quick-drying layer.

[0027] Technical Solution 8 further specifies the denier and fiber count of the polyester yarns for the moisture-absorbing layer and the quick-drying layer. The fine denier yarn used in the moisture-absorbing layer can form a dense capillary network, thereby ensuring the moisture-absorbing effect of the moisture-absorbing layer. The coarse denier yarn used in the quick-drying layer has lower capillary pressure, which can ensure that moisture is forcibly transferred unidirectionally from the moisture-absorbing layer to the quick-drying layer.

[0028] Technical Solution Nine specifies the material combination of the core-spun yarn: the core material is polytetrafluoroethylene (PTFE) filament, and the sheath is polyester staple fiber. The high hydrophobicity of PTFE effectively prevents moisture from seeping back from the quick-drying layer to the moisture-absorbing layer. The sheath composed of polyester staple fiber has suitable hydrophilicity to absorb moisture from the moisture-absorbing layer, and its structure is more porous than that of the filament, with more end groups and voids, further enhancing its ability to absorb and temporarily store moisture from the moisture-absorbing layer.

[0029] Technical Solution 10 provides a quick-drying and breathable garment. When worn, sweat produced by the body is rapidly absorbed and unidirectionally conducted to the outer layer of the garment, where it evaporates quickly, thus avoiding the damp, cold, and sticky feeling that traditional clothing produces after sweating. Simultaneously, the perforated unit structure throughout the fabric ensures excellent breathability, effectively dissipating heat and moisture and preventing stuffiness. The overall elasticity and stability design of the fabric ensures that the garment maintains a comfortable fit, good freedom of movement, and long-term functional durability during various activities, providing the wearer with a dry and comfortable experience all day long.

[0042] Example

[0043] This utility model embodiment relates to a quick-drying and breathable fabric, referring to... Figure 1 and Figure 2The fabric body comprises an integrally woven fabric body, which includes, from the inside to the outside, a moisture-absorbing layer 1, a moisture-permeable layer 2, and a quick-drying layer 3 along its thickness direction, and is provided with multiple perforated units 4 along the thickness direction; each perforated unit 4 is a conical channel with an opening size that gradually increases from the inside to the outside; the inner surface of the moisture-absorbing layer 1 is woven with yarns to form several closely arranged protrusions 5, and recesses are formed between adjacent protrusions 5; the moisture-absorbing layer 1 and the quick-drying layer 3 are woven with polyester yarns, and the denier of the polyester yarns used in the quick-drying layer 3 is greater than that of the polyester yarns used in the moisture-absorbing layer 1, and the polyester fibers in the polyester yarns used in the quick-drying layer 3 have irregular cross-sections; the moisture-permeable layer 2 is woven with core-spun yarns, and the water contact angles of the fiber materials used in the core material and the sheath of the core-spun yarns are 100 to 140 degrees and 10 to 50 degrees, respectively.

[0044] The following sections will describe in detail the structure and manufacturing method of the moisture-absorbing layer 1, the moisture-permeable layer 2, and the quick-drying layer 3.

[0045] First, the moisture-absorbing layer 1 will be described. Specifically, this moisture-absorbing layer 1 is the innermost layer of the fabric, and its inner surface, which directly contacts the skin, has a three-dimensional structure. This surface is not flat, but consists of a large number of closely arranged, independent dot-like or island-like protrusions 5. These protrusions 5 are arranged in a dense matrix on the fabric plane, and their apexes constitute the main contact points between the fabric and the skin. Between adjacent protrusions 5, interconnected grid-like or dot-like moisture-absorbing grooves are formed. In cross-section, the surface of this layer presents a wave-like undulating shape. The three-dimensional structure of the moisture-absorbing layer 1 is formed on a double-sided circular knitting machine through specific needle arrangement and knitting techniques. Specifically, by combining tucking and floating at specific needle positions, some yarns form closely arranged protrusions 5 on the fabric surface that are higher than the fabric plane, while areas without tucking or floating naturally form recesses. To achieve efficient capillary action, this layer is preferably woven using fine denier porous polyester yarn of 40D / 70F or 50D / 70F. To enhance the fabric's fit and elasticity, spandex yarn, such as 20D or 30D bare spandex yarn, can be fed in simultaneously during weaving, allowing it to twist together with the polyester yarn. The spandex accounts for 3% to 5% of the total weight of this layer. The resulting moisture-absorbing layer 1 has a textured inner surface, with raised portions 5 forming dotted contact with the skin and recessed portions forming moisture-absorbing channels.

[0046] Next, the moisture-permeable layer 2 will be described. Specifically, this layer is located between the moisture-absorbing layer 1 and the quick-drying layer 3, playing a crucial role in one-way moisture wicking. Its core is a specially structured core-spun yarn. This yarn can be made using core-spun spinning techniques such as air-jet vortex spinning or ring spinning. Its core material is a highly hydrophobic filament, preferably a circular cross-section polytetrafluoroethylene (PTFE) filament; its sheath is composed of hydrophilic short fibers, preferably polyester short fibers. The hydrophilic polyester short fiber sheath ensures that this layer can effectively absorb moisture from the moisture-absorbing layer 1, while the hydrophobic PTFE core material forms a physical barrier, utilizing its high surface tension resulting from a water contact angle greater than 100 degrees to prevent moisture from seeping back from the outer layer to the inner layer. During the integrated weaving process, this core-spun yarn constitutes the middle layer of the fabric body, tightly bonded to the moisture-absorbing layer 1 and the quick-drying layer 3.

[0047] Finally, the quick-drying layer 3 will be described. Specifically, this quick-drying layer 3 is the outermost layer of the fabric, and its outer surface is relatively smooth. Structurally, this layer is woven from coarser denier polyester yarns, and the gaps (i.e., porosity) formed between the yarns are significantly larger than those in the moisture-absorbing layer 1. The core structural feature of this layer lies in the polyester fibers that make up the yarns themselves. These polyester fibers are as follows... Figure 4 The irregularly shaped cross-section of polyester fiber 7 is shown. The cross-section of each polyester fiber is not circular, but rather Y-shaped or propeller-shaped (cloverleaf-shaped) irregularly shaped. The Y-shaped cross-section resembles the letter "Y," with three blades radiating outwards from a central point; see reference... Figure 4 The propeller-shaped cross-section has four or more blades. Multiple open grooves or channels running along the fiber axis are formed between these blades, constituting a microscopic channel network on the fiber surface. This layer is preferably woven from coarse denier polyester yarn in the range of 75D / 34F to 150D / 68F. The irregularly shaped polyester fibers can be achieved by using specially shaped spinneret orifices during polyester melt spinning. For example, a Y-shaped spinneret orifice with three radial slits or a propeller-shaped spinneret orifice with four blades can be used. The extruded melt, after cooling and solidification, forms fibers with the corresponding cross-sectional shape.

[0048] Among them, reference Figure 1 and Figure 2The perforated unit 4 is formed by sequentially stacking through holes on the moisture-absorbing layer 1, the moisture-permeable layer 2, and the quick-drying layer 3, and the radial dimension of each through hole in its respective moisture-absorbing layer 1, moisture-permeable layer 2, or quick-drying layer 3 remains consistent in different positions along the axial direction. Specifically, from an overall perspective, each perforated unit 4 presents itself in three-dimensional space as a hollow frustum-shaped channel that is wider at the top and narrower at the bottom (i.e., wider on the outside and narrower on the inside). The sidewall of this channel is formed by the walls of the through holes aligned on the three layers of fabric. The opening of this channel on the moisture-absorbing layer 1 side is the narrow end of the frustum, and the opening on the quick-drying layer 3 side is the wide end of the frustum, with the opening size gradually increasing smoothly from the inside to the outside. The through holes on each layer are themselves cylindrical (non-conical) holes. These perforated units 4 are knitted in one go on a double-sided circular knitting machine by controlling the needle selection and loop shifting actions of the knitting needles through a preset jacquard program. Specifically, on the needle plate on the absorbent layer 1 side, a smaller opening is formed by transferring loops from a specific needle to an adjacent needle; simultaneously, on the needle cylinder on the quick-drying layer 3 side, a larger opening is also formed at the corresponding position by transferring loops. Since the breathable layer 2 is located between the two and is knitted together, a through channel is naturally formed.

[0049] Furthermore, referring to Figure 1 , Figure 2 and Figure 3 The perforated units 4 are hexagonal in shape on the plane of the fabric body. Specifically, the perforated units 4 are not arranged closely together on the fabric body, but are spaced apart by a certain distance, thus forming an array with a specific shape. Each regular hexagonal perforated unit 4 is defined by six vertices and six sides connecting the vertices, and its sides are formed by the arrangement direction of the knitting loops. This arrangement allows the fabric to maintain a high open area ratio while forming a stable and uniform geometric network in structure. In the jacquard program design of the knitting machine, the loop transfer action is set to cycle in units of six vertices, thereby forming a regular, closely arranged array of regular hexagonal perforations on the fabric plane.

[0050] Preferably, the diagonal length of the through-hole in the moisture-absorbing layer 1 is 0.5-1.0 mm, and the diagonal length of the through-hole in the quick-drying layer 3 is 1.5-2.0 mm. Specifically, the distance between the two opposite vertices (i.e., the diagonal length) of the regular hexagonal through-hole on the inner moisture-absorbing layer 1 is a smaller value, between 0.5-1.0 mm. The diagonal length of the regular hexagonal through-hole on the outer quick-drying layer 3 is a larger value, between 1.5-2.0 mm. The diagonal length of the through-hole in the middle moisture-permeable layer 2 is between these two values. By precisely controlling the number of stitches and the spacing during the transfer in the knitting machine's transfer program, the hole diameter can be set. For example, a small-span transfer operation can be performed on the moisture-absorbing layer 1 side, while a large-span transfer operation can be performed on the quick-drying layer 3 side. This dimensional differentiation design works together to form a gradient channel structure, which helps to guide moisture from the inside of the fabric with higher pressure to the outside of the fabric with lower pressure, thus accelerating its diffusion.

[0051] In addition, refer to Figure 3 The apex positions of the through holes in the moisture-absorbing layer 1, the breathable layer 2, and the quick-drying layer 3 are fixed by reinforcing yarns 6 that penetrate along the thickness direction of the fabric body; the reinforcing yarns 6 are elastic yarns. Specifically, at each of the six vertices of each regular hexagonal hole unit 4, an independent elastic reinforcing yarn 6 passes through all three layers of fabric in a direction substantially perpendicular to the fabric plane. This reinforcing yarn 6 is preferably bare spandex yarn or spandex-covered yarn, which has excellent elastic recovery properties. During the weaving process, the elastic reinforcing yarn 6 is fed in at specific times by an independent yarn guide and is woven only on the needles corresponding to the vertices of the hexagonal through holes, so that it firmly connects the three layers of fabric together at those vertices like rivets. This not only prevents interlayer slippage and ensures the structural integrity of the conical channel, but also gives the entire fabric excellent tensile resilience, allowing it to maintain its original shape and function after wearing and washing.

[0052] This embodiment relates to a quick-drying and breathable fabric. The fabric body includes a moisture-absorbing layer 1, a breathable layer 2, and a quick-drying layer 3 stacked sequentially. Through the cooperation of these three layers, efficient and unidirectional moisture transfer and quick-drying of the fabric are achieved. First, when the human body sweats, sweat accumulates on the skin surface, producing a damp, cold, and sticky discomfort. The moisture-absorbing layer 1 is in direct contact with the skin. It has a tightly arranged structure of protrusions 5 and depressions formed by yarn weaving. The protrusions 5 form point contact with the skin, reducing the actual contact area between the fabric and the skin, thereby reducing the sticky feeling caused by the fabric becoming wet. At the same time, the depressions formed between adjacent protrusions 5 can actively and quickly absorb liquid sweat from the skin surface into the fabric interior by utilizing capillary effect. This structure not only increases the surface area in contact with sweat and accelerates the moisture absorption process, but also provides an initial channel and driving force for sweat to migrate to the outer layer. Furthermore, the absorbent layer 1, which comes into direct contact with the skin, utilizes its dense capillary network formed by fine denier polyester fibers to generate a capillary effect, rapidly absorbing liquid sweat from the skin surface into the fabric's interior. Therefore, the macroscopic structure and weave structure of the absorbent layer 1 work synergistically to further improve its absorbency. Subsequently, the intermediate permeable layer 2 plays a crucial role in unidirectional permeability. The core-spun yarn used in this layer has a hydrophilic outer layer (water contact angle 10-50 degrees) that actively draws moisture from the absorbent layer 1; while its hydrophobic core material (water contact angle 100-140 degrees) forms a physical barrier, using the difference in surface energy to prevent moisture from seeping back from the permeable layer 2 towards the absorbent layer 1. This design ensures unidirectional sweat conduction, solving the problem of moisture backflow and subsequent skin re-wetting under pressure, a common issue with traditional fabrics. Moisture transferred from the breathable layer 2 enters the quick-drying layer 3. Because this layer uses coarse denier polyester yarn, the larger pores between the fibers facilitate rapid diffusion and spread of the moisture. More importantly, the polyester fibers with irregular cross-sections used in this layer have a much larger specific surface area than circular cross-section fibers, significantly increasing the contact area between moisture and air. Moisture spreads rapidly along the fiber direction within the grooves on the surface of the irregular cross-section fibers, forming a thinner water film, thus significantly increasing the evaporation rate and achieving rapid drying. Furthermore, the tapered channels that run through the three layers and gradually widen from the inside out provide an additional, efficient path for moisture transfer. This channel structure, smaller inside and larger outside, helps guide the high-humidity air inside to diffuse directionally into the low-humidity environment outside, further improving the overall breathability of the fabric and preventing a stuffy feeling.In summary, the quick-drying and breathable fabric provided by this technical solution integrates a moisture-absorbing layer 1 with a specific physical structure, a breathable layer 2 with unidirectional breathability, and a quick-drying layer 3 with high evaporation capacity into a single weave, supplemented by a through-hole conical perforation unit 4. While ensuring the softness and comfort of the fabric itself, it constructs a highly efficient unidirectional breathability system. This system can quickly absorb sweat from the skin surface, forcibly conduct it unidirectionally to the outer layer of the fabric, and finally evaporate it quickly, thereby providing the wearer with a lasting dry and comfortable experience.
