Description

Technology Field

[0001] The present invention relates to a textile fabric, and more specifically, to a textile fabric comprising a structure that improves the textile wicking phenomenon. Background Technology

[0002] When wearing clothing, sweat generated by the human body tends to temporarily accumulate on the body's surface, and if this sweat is not properly released to the outside, the wearer experiences significant discomfort. Particularly in situations involving high levels of indoor and outdoor activity, the amount of sweat pooled on the skin surface increases; if there is a delay in the process of the fabric absorbing this sweat, both the skin and the fabric become damp simultaneously. This dampness can cause a rapid drop in body temperature, or conversely, prevent sweat from evaporating, leading to problems where proper body heat reduction does not occur in high-temperature environments.

[0003] Conventional fibers based on prior art are mostly manufactured based on a circular cross-section, characterized by a simple cross-sectional structure. This simple cross-sectional structure presents a problem in that the capillary space formed on the fiber surface is limited, resulting in insufficient pathways for absorbing and transporting moisture. In particular, while it is advantageous to provide micro-grooves or protrusions on the fiber cross-section to facilitate the rapid diffusion of low-viscosity moisture, such as sweat, conventional circular cross-section fibers have lacked these functional elements.

[0004] Fiber yarns produced by conventional spinning methods also consist of a structure in which numerous fibers are simply twisted and bonded together; consequently, the capillary channels formed at the contact surfaces between fibers tend to be irregular and lack continuity. This irregularity in the channels hinders the rapid movement of moisture in a specific direction and delays its diffusion throughout the entire fiber. As a result, sweat accumulates in localized areas, and the rates of external diffusion and evaporation are significantly reduced.

[0005] In conventional technology, surface coatings or chemical processing treatments are applied to improve moisture absorption rates. However, these treatment methods have the problem that performance is prone to degradation during continuous washing, and over time, the processing layer peels off, making it difficult to maintain the original performance. Additionally, if the coating layer is thick, it reduces the breathability of the fiber itself, causing side effects such as a stuffy feeling when wearing the clothing.

[0006] In addition, while methods involving the blending of functional fibers into clothing materials are also used, it is difficult to significantly improve the overall wicking performance of the fabric if the functional fibers are included below a certain proportion. Although an improvement is needed to stably secure moisture transport pathways based on structural interactions between fibers, conventional blending methods have remained at the level of merely changing the type of material, failing to fundamentally resolve structural problems.

[0007] Techniques for forming fine grooves or irregularities on the fiber surface have also been proposed. However, such irregular structures are mostly limited to only a portion of the fiber surface, making it difficult to form continuous capillary pathways. Simple irregular structures lacking gradually narrowing grooves or radial structural elements had limitations in sufficiently improving the actual movement speed of sweat. Since capillary action does not continue smoothly when the irregularities lack continuity, moisture absorption and transport performance were limited.

[0008] The internal structure of the fiber yarn, formed by spinning multiple fibers, is another element that requires improvement. While the conventional spinning method can increase the bonding strength between fibers, it has the disadvantage of making it difficult to precisely design the capillary formation structure. If fibers are arranged randomly, excessive gaps may form in some areas, or conversely, regions of excessive compression may occur, making it difficult to secure uniform moisture transport pathways. This non-uniformity even increases the likelihood of the fiber yarn structure deforming during long-term use.

[0009] Furthermore, for smooth evaporation to occur during the process of transferring sweat to the outside, airflow must move along with it; however, most conventional fibers are structured without considering these airflow pathways. If airflow is blocked, absorbed moisture becomes stagnant within the fiber, and since the time to fiber saturation is shortened, it is difficult to expect a sufficient wicking effect. Therefore, a technical structure is required that utilizes the internal space of the fiber to simultaneously induce natural air movement and moisture diffusion.

[0010] Furthermore, in the case of fabrics with a simple inter-fiber bonding structure, the fibers themselves lack rotational protrusions or screw threads, making it difficult to form capillary channels through interlocking. If the fibers are loosely positioned within the fabric, sweat movement becomes irregular and slows down, leading to problems where it becomes difficult to provide uniform wicking performance across the entire fabric. In fact, to satisfy the long-duration wicking performance required for sportswear or functional clothing, innovation in the inter-fiber bonding structure itself was necessary.

[0011] The structural limitations of such conventional technology have caused various problems, including reduced comfort experienced by users during activities, decreased sustained performance due to rapid saturation, and difficulty in controlling heat sensation within the garment. Particularly in the field of functional clothing, since wicking speed and evaporation speed determine the overall performance of the garment, it was difficult to satisfy the required performance with simple surface treatments or mixed fiber methods. Conventional technology required fundamental improvement because key elements such as fiber cross-sectional structure, fiber yarn formation method, and internal fabric binding structure were not designed to be suitable for enhancing functionality.

[0012] Consequently, the fiber and yarn structures of the prior art failed to form the continuous and three-dimensional capillary structure required for the series of processes involving the absorption, transport, diffusion, and evaporation of sweat, nor did they possess an evaporation-promoting structure that takes air flow into account. Due to these technical limitations, problems with the prior art have been continuously raised, and the present invention is based on the technical intention to solve these very problems. Prior art literature

[0013] Korean Registered Patent Publication No. 10-0758638 (Registration Date: September 7, 2007) The problem to be solved

[0014] Textile fabrics according to the prior art have limitations in rapidly absorbing sweat from the skin surface and transferring it to the outside due to their circular cross-sectional structure and simple spinning structure. Furthermore, they fail to sufficiently induce capillary action, resulting in a slow rate of evaporation and prolonged dampness. Additionally, continuous and regular capillary pathways are not formed within the fibers, causing sweat to stagnate at specific points, and there is a problem of reduced comfort due to insufficient breathability. Therefore, the objective of the present invention is to require a new textile fabric that improves functional performance without compromising the tactile feel and comfort of the garment, while simultaneously requiring structural improvements to rapidly absorb, transport, and diffuse moisture formed on the skin. means of solving the problem

[0015] A fiber fabric according to one aspect of the present invention for achieving such an objective may be composed of a plurality of fiber yarns formed by spinning a plurality of fibers having a cross-sectional structure in a cross-section and weaving them together.

[0016] In one embodiment of the present invention, the fiber may be configured to include: a groove forming portion formed concavely on the side of the fiber by the cross cross-sectional structure being continuously formed along the length direction of the fiber; and a corner forming portion formed convexly on the side of the fiber by the cross cross-sectional structure being continuously formed along the length direction of the fiber.

[0017] In one embodiment of the present invention, the cross cross-section structure may be a structure that extends radially, spaced 90 degrees from the center.

[0018] In this case, each radial extension may have a structure in which the width gradually decreases towards the end.

[0019] In addition, a round structure having a radius of curvature of a predetermined size can be formed at the end of each radial extension.

[0020] In one embodiment of the present invention, the fiber may be configured to include a capillary channel forming part in which a plurality of fibers are spun to form a groove forming part and a corner forming part interlocking with each other, and is continuously formed along the extended length direction of the fiber, and forms a capillary structure that rapidly absorbs sweat and evaporates it to the outside upon contact with the skin.

[0021] In one embodiment of the present invention, the fiber may be configured to include a helical interlocking structure forming part in which a plurality of fibers are spun to form a groove forming part and a corner forming part interlocking with each other, continuously rotates along the extended length direction of the fiber to form a screw thread structure, and interlocks with a screw thread structure formed on another fiber to form another capillary structure. Effects of the invention

[0022] The fiber fabric according to the present invention forms the fiber cross-section into a cross-sectional structure, thereby securing continuous groove and edge structures along the longitudinal direction of the fiber, which has the effect of naturally enhancing capillary action on the fiber surface. The complex and three-dimensional cross-sectional shape provides a path that rapidly draws up and moves sweat, giving it the characteristic of allowing moisture from the skin to be absorbed into the fabric within a short period of time. Furthermore, the radially extended cross-sectional structure has its ends finished in a rounded shape to ensure the continuity of moisture flow, thereby having the advantage of reducing loss or stagnation during the moisture movement process. The capillary channel forming part, formed by spinning multiple fibers, constitutes regular and continuous micro-passages within the fiber yarn, thereby increasing the speed at which sweat rapidly diffuses throughout the fabric and evaporates upon contact with external air. Moreover, the helical interlocking structure forming part increases the bonding strength between fiber yarns and forms another capillary network through a rotary screw thread structure, thereby enabling simultaneous moisture movement inside and outside the fiber yarn. Through these structural features, the present invention provides a functional textile fabric that significantly improves moisture absorption and quick-drying performance and maintains a comfortable thermal sensation and tactile feel even when worn for a long time.

Specific details for implementing the invention

[0024] Preferred embodiments of the present invention will be described in detail below with reference to the drawings. Prior to this, terms and words used in this specification and claims should not be interpreted as being limited to their ordinary or dictionary meanings, but should be interpreted in a meaning and concept consistent with the technical spirit of the present invention.

[0025] Throughout this specification, when it is stated that one component is located "on" another component, this includes not only cases where one component is in contact with another component, but also cases where another component exists between the two components. Throughout this specification, when it is stated that a part "includes" a component, this means that, unless specifically stated otherwise, it does not exclude other components but may include additional components.

[0026] FIG. 1 shows a perspective view of fibers and fiber yarns constituting a fiber fabric according to one embodiment of the present invention, and FIG. 2 shows a partial enlarged view of the fibers shown in FIG. 1.

[0027] Referring to FIGS. 1 and 2, the fiber fabric according to the present embodiment is composed of weaving a plurality of fiber yarns (120) formed by spinning a plurality of fibers (110) having a cross-sectional structure (111) in a cross-section, thereby allowing for the rapid absorption of sweat and subsequent evaporation to the outside to maximize comfort, and at the same time, providing a fiber fabric that can also improve the wearing comfort.

[0028] Hereinafter, with reference to FIGS. 1 to 3, each component constituting the fiber fabric according to the present embodiment will be described in detail.

[0029] Detailed description of the fiber (110)

[0030] The fiber (110) is a basic unit constituting the fiber fabric of the present invention and is manufactured in the form of a single filament or multiple filaments, and is characterized by having a continuous functional cross-sectional structure formed along its length direction. The fiber (110) can be made of various materials including synthetic fibers, semi-synthetic fibers, or natural fibers, but a filament form based on a thermoplastic polymer is particularly suitable for realizing wicking performance. This choice of material provides the advantage of being able to precisely form the cross-sectional shape and continuously maintain the desired structure during the spinning process.

[0031] In the manufacturing process, the fiber (110) is manufactured using a cross-sectional structure proposed in the present invention instead of a circular cross-section, and this structure increases the surface area of ​​the fiber and naturally forms fine moisture transport pathways. While conventional circular cross-sectional fibers have a limited surface area and thus a slow rate of moisture absorption such as sweat, the composite cross-section formed in the fiber (110) exhibits the characteristic of rapidly attracting moisture even with a small amount of contact. This structural difference has the effect of significantly improving moisture absorption efficiency even at the same fiber thickness.

[0032] The fiber (110) is designed to have excellent durability to withstand various usage environments, such as friction with the external environment, repeated washing, and high temperature and high humidity conditions. The material properties are adjusted so that the overall strength of the fiber is not weakened even if cross-shaped protrusions are naturally formed on the surface of the fiber, and the molecular arrangement direction in the spinning process is optimized so that tensile strength is maintained even if the cross-section is complex. This durable design contributes to maintaining the wicking function stably by minimizing structural deformation of the fiber during long-term use.

[0033] The structural irregularities formed on the outer surface of the fiber (110) are not merely for wicking purposes, but also serve to increase the interlocking bonding strength when spun into fiber yarn (120). This forms the basis of the capillary channel forming part or helical interlocking structure proposed in the present invention, and strengthens the bonding strength between fibers to prevent the fiber yarn from deforming or unraveling. In other words, the fiber (110) is a component that performs not only an independent function but also a function that supports the structural stability of the entire fiber yarn.

[0034] The fiber (110) maintains its structural function even after the fiber yarn and fabric composition, playing a key role in determining the moisture absorption and quick-drying performance of the entire fabric. The continuous cross-sectional structure formed by the fiber (110) forms a wicking network throughout the fabric and helps moisture move and spread quickly without remaining at a specific point. This contributes significantly to maintaining comfort when wearing the clothing and serves as a basic technological element that can be utilized throughout the high-performance fiber industry, such as sportswear, functional clothing, and quick-drying clothing.

[0035] Detailed description of the cross cross-section structure (111)

[0036] The cross-sectional structure (111) is a core structure constituting the cross-section of the fiber (110) and is formed in a shape that includes four protrusions extending radially from the center of the fiber outward. Unlike a simple square or circular cross-section, this structure has the effect of significantly increasing the surface area of ​​the fiber due to its complex shape composed of multiple protrusions. An increase in surface area widens the contact area between the fiber and moisture, thereby promoting natural absorption and significantly improving the initial wicking speed.

[0037] The cross-sectional structure (111) is designed so that each radial extension is spaced at equal angles from the center, thereby ensuring structural stability that can maintain the balance and strength of the entire fiber. For example, four protrusions spaced at 90-degree intervals maintain the balance of the fiber cross-section and disperse the distribution of external stress, thereby reducing the problem of the fiber being deformed or crushed. This arrangement provides the effect of maintaining the cross-sectional structure even when the fiber is exposed to repetitive pressure and deformation while the user is moving.

[0038] The radial extension of the cross-sectional structure (111) is designed to be maintained continuously along the longitudinal direction and, unlike a simple uneven structure, has a continuous structural pattern that forms a moisture transport pathway. As the end portion of the protrusion is configured to gradually narrow, capillary action naturally occurs in that area. This gradually narrowing structure guides moisture to the end of the protrusion, and has the advantage of maintaining a stable path in the direction of movement so that the moisture flow is not interrupted.

[0039] The cross cross-section structure (111) is configured with a round shape having a radius of curvature at the end of the protrusion, thereby preventing the problem of reduced durability that can occur in a sharp cross-section structure. The round structure relieves cross-sectional stress concentration and contributes to reducing damage to the fibers during repeated washing and friction processes. In addition, the round shape allows moisture to naturally diffuse from the end of the protrusion, thereby serving to stably maintain the wicking direction.

[0040] The cross-sectional structure (111) serves as a basis for forming capillary channels and helical structures by facilitating inter-fiber bonding during the formation of fiber yarns (120) as well as moisture transfer. Because the arrangement of the protrusions intertwines with one another and has a certain regularity, micro-passages are naturally formed inside the fiber yarns, which act as a continuous moisture transport network. Consequently, the cross-sectional structure serves as the starting point of the wicking network, which is a core function of the entire invention, and is an important element that fundamentally improves the performance of the fabric.

[0041] Detailed description of the groove forming part (112)

[0042] The groove-forming portion (112) is a concave structure that is naturally formed between the radial protrusions of the cross-sectional structure (111) and is characterized by being formed continuously along the longitudinal direction of the fiber (110). This groove acts as a structural passage that forms the core of capillary action and helps sweat absorbed from the outside to move rapidly along the groove immediately after contacting the fiber. This continuous formation of the groove-forming portion (112) provides significantly higher moisture transport efficiency compared to conventional simple uneven structures.

[0043] The groove-forming portion (112) naturally lowers the contact angle with the fiber surface, thereby allowing even a small amount of moisture to be easily absorbed. Due to the way surface tension acts, the concave structure has the property of easily attracting moisture, which is an important factor in determining the initial absorption rate. Moisture that flows into the groove is drawn up inward by capillary pressure, thereby producing the effect of rapidly removing sweat from the skin surface.

[0044] The groove forming portion (112) is designed so that its depth and width are maintained at a constant ratio, thereby preventing the problem of moisture movement being interrupted or stagnated in the middle of the path. Since the groove is not only continuous in the longitudinal direction but also maintains a regular cross-sectional structure, the speed and direction of moisture movement are maintained stably and naturally connected to the newly formed capillary channels within the fiber. This structure plays an important role in maintaining the wicking performance of the entire fabric consistently.

[0045] The groove-forming portion (112) combines with the edge-forming portion (113) of an adjacent fiber when spun into a fiber yarn (120) to form another micro-channel. That is, beyond the functionality of operating independently, the groove-forming portion also performs the role of a connecting structure that forms a new capillary network at the fiber yarn stage. This is a key element of the multi-walking path formation presented in the present invention and serves as the basis for significantly improving moisture transfer performance compared to conventional fibers.

[0046] The groove-forming portion (112) is combined with a radial cross-sectional structure to secure a capacity capable of handling a rapid influx of sweat, while simultaneously having the structural advantage of allowing airflow to promote evaporation. The concave groove provides a space for air to flow inside even after moisture is filled, thereby helping to quickly release heat and moisture to the outside. Through this, the fiber fabric of the present invention can naturally and continuously carry out the processes of absorption, diffusion, and evaporation, which contributes significantly to the improvement of comfort compared to conventional technology.

[0047] Detailed description of the corner forming part (113)

[0048] The corner forming portion (113) is a convex structure that naturally protrudes when the radial extension of the cross-sectional structure (111) is formed, and is characterized by being continuously connected in the longitudinal direction of the fiber (110). This corner forming portion forms the outer boundary of each protrusion and plays an important role in increasing the surface area of ​​the fiber due to the structure protruding outward from the cross section. Due to the increase in surface area, the area in contact with moisture is widened, which helps the initial wicking reaction occur quickly.

[0049] The corner forming portion (113) has a protruding structure that is structurally contrasted with the groove forming portion (112), and when spun into a fiber yarn (120), this protrusion naturally interlocks with the groove of an adjacent fiber to form a fine capillary space. This structural connection acts as a key element in creating regular capillary paths within the fiber yarn. Since the cross-section of the protrusion is designed to maintain a constant angle and curvature, it is stably bound and has minimal deformation during the spinning process.

[0050] The curvature and protrusion of the corner forming portion (113) provide a function of controlling the moisture movement path. While excessively sharp protrusions may reduce durability, the present invention applies a gentle protrusion structure with a radius of curvature to simultaneously secure fiber wear prevention performance and moisture diffusion performance. This curvature structure smooths the process of moisture diffusing to the outside of the protrusion, thereby providing the effect of continuous capillary action.

[0051] The edge forming portion (113) also affects the fine contact environment between the fiber and the skin. Conventional circular cross-section fibers tend to have a sticky feeling when in contact with the skin over a wide area, but the three-dimensional structure in which protrusions and grooves intersect has the effect of finely dispersing the contact area with the skin. As a result, the feeling when in contact with the skin becomes lighter, and even before absorbing sweat, the breathability is high, providing a pleasant touch. This is an important factor in improving the wearability of functional clothing.

[0052] The corner forming section (113) helps moisture introduced into the fiber to spread in various directions, thereby improving the overall drying speed. Due to the cross-shaped structure with widely spaced protrusions, each protrusion acts as a branching point that disperses moisture in new directions, which contributes to increasing the speed at which moisture spreads throughout the fabric. Consequently, the corner forming section (113), together with the groove forming section (112), is a key functional structure that forms a multilayered and multidirectional capillary network.

[0053] Detailed description of the fiber yarn (120)

[0054] The fiber yarn (120) is a linear structure formed by spinning a plurality of fibers (110) and is a key component that forms a continuous capillary network by combining the functional cross-sectional structures proposed in the present invention. The fiber yarn (120) provides a continuous and regular wicking passage that was difficult to implement in the prior art by having the cross-sectional structure (111), groove forming part (112), and edge forming part (113) of individual fibers interlock to form a new space. This structure serves as the basis for securing stable moisture mobility throughout the fiber yarn.

[0055] During the spinning process, the fibers (120) are twisted and bound together, and during this binding process, microstructures such as capillary channel forming parts (131) are naturally created. The spaces created by the interlocking of the grooves and protrusions of each fiber maintain a constant width and depth and continue uninterrupted along the length of the fiber, serving as the main passages through which moisture flows intensively. This significantly improves the speed of moisture movement and allows liquids such as sweat to spread rapidly without remaining inside the fabric.

[0056] The structure of the fiber yarn (120) goes beyond being a simple fabric component and acts as a key functional structure that determines the moisture absorption and quick-drying performance of the entire fabric. Conventional spun yarns had problems with irregular and unstable moisture flow because the fiber arrangement was randomly formed, but the fiber yarn according to the present invention has the characteristic that the structural shape of each fiber interlocks regularly, so it has excellent structural consistency and stability. As a result, the moisture movement path is maintained uniformly throughout the spun yarn.

[0057] The fiber yarn (120) is designed to ensure spinning strength and durability so that components do not separate or capillary structures are not damaged even during repeated deformation and washing. Because the cross-sectional fibers within the fiber yarn are bound in an interlocking manner, they have high resistance to external pressure and tension and maintain the shape of the capillary passages. This is an important technical effect that allows the initial performance to be sustained even in clothing used for a long time.

[0058] When the fiber yarn (120) is woven into the fabric, the capillary passages extend not only within the fiber yarn but also at the contact surfaces between the fiber yarns, forming multiple moisture transport paths. This structure causes sweat to spread throughout the entire fabric rather than remaining only in specific fiber yarns, thereby maximizing the surface area in contact with air and increasing evaporation efficiency. In other words, the fiber yarn (120) functions not as a single functional element but as a network-centered structure that enhances the overall fabric performance.

[0059] Detailed description of the capillary channel forming part (131)

[0060] The capillary channel forming portion (131) is a micro-channel structure that is naturally formed as the groove forming portion (112) and the edge forming portion (113) of each fiber interlock during the process of spinning multiple fibers (110). This structure is configured to maintain a continuous and constant width and depth along the extended length direction of the fiber yarn (120) and functions as a passage for moisture flow. Unlike conventional randomly arranged spinning structures, in the present invention, fibers with designed cross-sectional shapes are regularly combined, so the continuity of the capillary channel is excellent, and stable moisture transfer performance can be secured.

[0061] The capillary channel forming part (131) is configured in a form where a concave groove and a protruding edge are combined, providing a structure that is highly advantageous for generating physical capillary pressure. The inside of the groove is configured in a curved shape to facilitate drawing up moisture by surface tension, and the edge forming part acts as a wall of the path to prevent moisture from escaping to the outside of the channel. This structural combination enables rapid ascent and movement immediately after moisture absorption.

[0062] The capillary channel forming part (131) performs the function of inducing moisture to flow in a certain direction within the fiber. Conventional fibers had a problem where moisture flowed in random directions and stagnated because the space between fibers was irregular, but the capillary channel of the present invention allows the moisture flow to continue stably in one long axis direction thanks to structural regularity. This plays a decisive role in rapidly diffusing sweat throughout the entire fiber and fabric after absorption.

[0063] The capillary channel forming part (131) also contributes significantly to the evaporation process after moisture has moved. Since the moisture moved through the channel is widely distributed on the surface of the fabric, the surface area in contact with air increases and the evaporation rate increases. In particular, this diffusion and evaporation structure provides a great advantage in fields requiring fast drying performance, such as sportswear or functional clothing. That is, the capillary channel is a dual-function structure that takes into account not only absorption but also evaporation.

[0064] The capillary channel forming part (131) is designed to maintain its structure even during repetitive movements or washing. Since the channel is formed based on the design characteristics of the fiber cross-section rather than a simple uneven structure, it is not easily damaged by external impact or tension. This is highly suitable for maintaining continuous performance required in functional clothing and can solve the problem of 'rapid performance degradation' that commonly occurs in conventional technology. Consequently, the capillary channel forming part (131) ensures long-term performance stability as a core functional element of the fabric of the present invention.

[0065] Detailed description of the helical interlocking structure forming part (132)

[0066] The helical interlocking structure forming part (132) is a structure designed to rotate and be arranged in the longitudinal direction when a plurality of fibers (110) are spun, forming a helical shape similar to screw threads throughout the fiber yarn (120). This structure deviates from a simple linear arrangement and additionally forms helical capillary spaces throughout the fiber yarn, which is an important component of the multilayer moisture transport path proposed in the present invention. The helical path serves to further increase the moisture transport speed and provides a shape that is more advantageous for fluid operation than the existing structure.

[0067] The helical interlocking structure forming part (132) has the characteristic of interlocking even between adjacent fibers, and the helical structures of each other are combined to provide a stronger bonding force. This reduces the phenomenon of fibers moving or spreading out when forming a fabric and contributes to maintaining a constant passage width. In conventional fiber structures, there was a problem where the capillary flow path was deformed when spinning was loose or irregular, but in the present invention, the screw thread structure helps maintain precise spatial consistency.

[0068] The helical interlocking structure forming part (132) establishes a multi-flow system by providing a path different from the capillaries formed by the grooves and edges in the cross-section. If the straight capillary channel acts as the main passage, the helical structure surrounds the main passage and acts as an auxiliary passage to distribute the flow so that moisture is not overloaded in a specific path. As a result, the moisture inside the fiber is diffused over a wide range, and the overall wicking speed is greatly improved.

[0069] The helical interlocking structure forming part (132) plays a significant role in minimizing structural deformation even when the fiber is used for a long time or repeatedly bent. Since the helical structure has mechanical characteristics that absorb external shocks and disperse tension, it is advantageous for maintaining its shape even under strong tensile force or torsional deformation. This means that the internal capillary pathways of the fiber can be maintained stably for a long period, contributing to the extension of the lifespan of the functional clothing.

[0070] The helical interlocking structure forming part (132) provides a structural advantage that favorably induces airflow even during the drying process of the entire fabric. The helical structure increases the surface area in contact with air as moisture diffuses along the channel, and secures a fine air movement path inside, thereby further accelerating the evaporation rate. This feature significantly improves the comfort of the garment, especially in high-intensity exercise environments or high-humidity conditions, and effectively improves the 'drying delay problem' that was not solved in conventional technology.

[0071] Five embodiments regarding a spinning structure capable of maximizing the fiber wicking phenomenon when forming a fiber yarn (120) by spinning a number of fibers (110) are described in detail.

[0072] Example 1; Straight capillary alignment type spinning structure

[0073] The linear capillary alignment type spinning structure is a method of spinning fibers by aligning them parallel so that the cross cross-sectional structure (111) of the fibers (110) is arranged as linearly as possible. In this structure, the groove-forming portions (112) between the fibers are connected in the longitudinal direction and are optimized to form regular and linear capillary channels. Unlike a general random twist structure, in this embodiment, the spinning tension is adjusted so that the fibers do not cross each other and are maintained in a linear arrangement.

[0074] This linearly aligned structure allows capillary pressure to act continuously in a constant direction, enabling moisture to move rapidly from one end of the spun yarn to the other. Moisture stagnation is minimized, and absorbed sweat is immediately pulled up along the length. This is one of the fundamental principles for maximizing wicking speed, and capillary channels remain constant even with a high moisture supply.

[0075] Furthermore, the linear arrangement features a structure where the grooves and edges of the fiber cross-section interlock repeatedly, offering the advantage of maintaining a constant channel width and depth. Because the capillary path is linear, the compression and expansion of moisture flow are minimized, resulting in almost no energy loss during transport. Consequently, moisture absorbed from the surface moves inward immediately, maintaining a rapid drying speed.

[0076] Since the fibers are maintained at a constant tension during the spinning process, the overall structure of the yarn is stable, and the capillaries do not break even under repeated deformation. Generally, the internal structure of spun yarn is prone to collapse under specific pressure due to random arrangement, but this embodiment features a uniform arrangement, resulting in increased durability. This enables long-lasting wicking performance in functional clothing.

[0077] This spinning structure is primarily suitable for applications requiring rapid sweat movement, such as sportswear and running wear, and offers significant advantages, particularly in high-performance textile products that must immediately wick moisture away. The linear capillary network can rapidly transport large volumes of moisture, enabling comfort to be maintained even in extreme environments.

[0078] Example 2: Spiral concentrated capillary spinning structure

[0079] The spiral concentrated capillary spinning structure is a structure designed to rotate the entire fiber yarn at a certain angle and arrange it in a spiral direction during the process of spinning the fiber (110). This is a method that extends the principle of the helical interlocking structure forming part (132) to make the entire fiber yarn have one large screw thread structure. The grooves and edges of the fiber are connected spirally, creating multiple moisture channels.

[0080] The helical structure induces moisture to move within the fibers not only along linear paths but also along rotational paths, ensuring that moisture is dispersed through various routes rather than remaining stagnant. This increases moisture throughput and demonstrates high processing capacity even in environments where sweat volume increases rapidly. Furthermore, the helical structure generates an increased surface area, thereby accelerating the absorption rate.

[0081] The spiral capillaries within the fibers utilize a wider area than straight capillaries, ensuring that the drying speed is maintained evenly across the entire fabric. This prevents excessive wetting in specific areas and allows moisture to rapidly diffuse around the fibers. This is crucial for enhancing comfort.

[0082] Since a constant rotational force is applied during the spinning process, the internal structure of the fiber becomes robust, and the overall structure remains stable even under repetitive twisting or tension. The helical path naturally disperses deformation caused by tension, reducing the possibility of capillary collapse. This is a significant advantage in high-intensity operating environments.

[0083] This structure is optimized for textile products requiring continuous sweat wicking and repetitive movement, such as hiking wear, mountaineering wear, and training wear. The spiral concentrated capillaries provide uniform walking performance even during prolonged activity and maintain rapid diffusion and evaporation effects.

[0084] Example 3: Multilayered capillary network spinning structure

[0085] The multilayered spinning structure is a method of spinning in which multiple fibers (110) are arranged in a multilayer structure, and is designed so that double or triple layers form capillaries in layers. Each layer forms a moisture movement path in multiple directions by having different directions of the cross-sectional structure (111). This structure forms a wider and three-dimensional network than a single capillary layer.

[0086] Since the groove-forming portions (112) of the fibers in each layer are arranged in different directions, moisture does not move in only one direction but diffuses through multiple intersecting paths. This solves the problem of specific path stagnation that commonly occurs in conventional technology and makes the movement of moisture more natural and free. As moisture diffuses, the evaporation area is maximized.

[0087] The multilayer structure uniformly distributes pressure changes that may occur during moisture transport, and if one zone becomes saturated, another layer can provide support. This increases overall drying efficiency and offers significant advantages, particularly in high-humidity environments. The interlayer structure also increases the wicking speed.

[0088] It is designed so that each layer is formed separately during the spinning process and then finally integrated, and the corner forming part (113) acts as a joining point to increase the cohesion between layers. This maintains the multilayer structure firmly and prevents the problem of separation between layers due to repeated washing or tension. The overall structure is very stable.

[0089] Multilayered networks are highly effective, primarily in all-season functional fabrics or base layers that come into direct contact with the skin. They are useful in product categories that require a balanced combination of heat retention, breathability, and drying functions, as well as rapid moisture transfer.

[0090] Example 4: Compression-Expansion Repeating Spinning Structure

[0091] The compression-expansion repeating spinning structure is a structure that applies a repeating pattern to regularly narrow and widen the arrangement spacing of the fibers (110) during the spinning process. That is, the spinning tension is adjusted so that the fibers are densely packed in certain sections and the spacing widens in other sections. In this process, capillary spaces of various sizes are formed.

[0092] In the dense section, high capillary pressure is generated to rapidly draw up moisture, while in the expanded section, a large surface area is secured, providing space for moisture to diffuse. The repeating pattern of these two structures achieves an optimal balance of the absorption-diffusion-evaporation processes. Conventional technology used only a single structure, which resulted in a problem of functional imbalance.

[0093] Furthermore, since moisture collects in the compression zone and rapidly moves to the expansion zone, it effectively prevents moisture from becoming saturated at a specific point. As moisture spreads widely in the expansion zone, the evaporation rate increases, shortening the drying time for the entire fabric. This method is particularly advantageous in environments with high sweating.

[0094] During the spinning process, this compression-expansion pattern is realized through precise tension control, allowing for adjustment of the overall arrangement pattern without affecting the fiber cross-sectional structure. The orientation and angle of the fibers are adjusted to maintain capillary persistence despite the repetitive structure. This also helps ensure mechanical stability.

[0095] This structure is suitable for applications requiring both rapid absorption and drying, such as quick-drying t-shirts, layered base garments, and indoor / outdoor sportswear. The combination of capillary structures of various sizes effectively maximizes wicking performance.

[0096] Example 5: Random-uniform hybrid spun structure

[0097] The random-uniform hybrid spinning structure is designed so that part of the fiber arrangement intentionally maintains a random form, while another part maintains uniform alignment. This allows predictable wicking paths and unpredictable diffusion paths to coexist within the fiber. It is a structure that combines the advantages of both arrangement methods.

[0098] In uniformly aligned sections, immediate moisture ascent occurs through rapid linear movement, while in randomly arranged sections, natural diffusion takes place in various directions. The combination of linear movement and multidirectional diffusion significantly improves overall moisture transport efficiency. This overcomes the 'limitations of unidirectional movement' that conventional technology has failed to address.

[0099] The random arrangement sections are resistant to structural deformation, serving to distribute the yarn load and absorb tension changes. The uniform arrangement provides structural stability, while the random arrangement distributes stress. The complementary relationship between the two structures helps maintain capillary pathways even during long-term use.

[0100] Furthermore, the amorphous capillary structures formed in the random arrangement sections create fine diffusion pockets that are difficult to form in a uniform structure, thereby finely dispersing moisture. This increases the evaporation surface area and enables rapid diffusion. A multi-layered diffusion structure is naturally formed.

[0101] This structure can be utilized in various fields, such as everyday wear, quick-drying underwear, and high-performance sportswear, and is particularly effective in maintaining comfort in environments requiring prolonged wear. The flexible structure, which combines uniformity and randomness, offers the advantage of ensuring both functionality and comfort.

[0102] Five embodiments of a material capable of stably forming a cross-sectional structure and facilitating natural moisture absorption and movement (110) are described in detail.

[0103] Example 1: Polyester (PET)-based functional filament material

[0104] Polyester (PET)-based filaments are thermoplastic polymer materials highly suitable for forming cross-sectional structures. Since PET maintains stable viscosity during the melt spinning process, cross-sectional shapes can be precisely formed, and it is easy to continuously maintain the same cross structure at the spinning nozzle. This molding stability is a critical factor in realizing the structural characteristics of the present invention.

[0105] Polyester possesses excellent durability and tensile strength, so it does not easily deform under external stress even with complex cross-sections such as a cross-sectional structure. This ensures that the fabric maintains its texture even under repeated friction or washing, providing long-term wicking performance. Additionally, its high thermal stability minimizes discoloration and deterioration.

[0106] Chemically, PET has a low property of directly absorbing moisture, but it is very advantageous for inducing capillary action utilizing surface tension. Due to the appropriate surface energy, moisture easily flows into the groove-forming portion (112), and when combined with a cross-sectional structure, rapid moisture mobility is exhibited.

[0107] In terms of spinning efficiency, PET filaments have high length strength, so they are easy to align with uniform tension during the spinning process. This makes the capillary channel forming part (131) stable, and has the advantage of maintaining the structure without the fibers slipping against each other during spinning.

[0108] As a result, the polyester-based fiber is a material that is very suitable for the fiber (110) of the present invention because it can simultaneously secure precise implementation of a cross-sectional structure, high structural stability, and excellent wicking promotion performance.

[0109] Example 2: Nylon (Nylon 6, 6.6) microfiber material

[0110] Nylon-based microfibers are a representative material capable of stably maintaining a cross-sectional structure due to their excellent flexibility and resilience. Nylon possesses high elasticity, ensuring that the protrusions and grooves of the cross-section do not easily collapse under external pressure, thereby securing the durability of the wicking structure. In particular, even after being woven into fabric, it exhibits superior shape recovery and high structural integrity over the long term.

[0111] In terms of physical properties, nylon exhibits excellent tensile strength and abrasion resistance, preventing damage to the cross protrusions caused by repetitive pressure or friction. Additionally, its flexible molecular chain structure ensures that the uniformity of the structure is maintained even during the spinning process. This makes it suitable for clothing and sportswear used for extended periods.

[0112] Chemically, nylon has a slightly higher moisture affinity than PET and can absorb a certain amount of moisture, which helps accelerate the initial absorption reaction in the groove-forming area. As moisture partially moves from the outside to the inside of the filament, it combines with the capillary structure to induce a faster wicking effect.

[0113] In terms of spinning efficiency, nylon ultrafine fibers have the characteristic of fine fibers being precisely bonded to each other, which is advantageous for forming multiple capillaries. The surface friction coefficient of the fibers is appropriate, so the bonding between fibers is stable, and the bonding effect of the corner forming part (113) is maximized.

[0114] Therefore, nylon microfiber material is suitable for realizing cross-sectional functional fibers due to its high flexibility, durability, and wicking-promoting performance.

[0115] Example 3: Polypropylene (PP) low-density lightweight functional material

[0116] Polypropylene (PP) is a material suitable for maximizing wicking action due to its very light density, strong water repellency, and fast drying speed. Because PP has a very low affinity for water, it has the characteristic of rapidly moving moisture over the surface rather than absorbing it internally. This is very advantageous for rapidly moving moisture along the grooves of the cross-sectional structure.

[0117] Due to its physical properties, PP has a low density, allowing for the construction of lightweight fibers even at the same thickness, which improves the wearability of the fabric. Additionally, it possesses excellent chemical resistance, reducing the risk of deterioration caused by sweat, detergents, and UV rays. This provides the durability suitable for clothing intended for outdoor activities.

[0118] The low surface energy level of PP's chemical properties actually helps enhance wicking performance. Since moisture does not adhere to the PP fibers, water entering the groove-forming areas moves rapidly and disperses outward. When combined with the increased surface area of ​​the cross structure, it exhibits very rapid diffusion and evaporation performance.

[0119] In terms of spinning efficiency, PP is a thermoplastic material that maintains its structure well during spinning and exhibits high shape stability at the spinneret, enabling the continuous formation of a uniform cross-section. Additionally, thanks to its lightweight properties, there is minimal tension variation during the spinning process, preventing lifting.

[0120] Overall, PP-based fibers possess ultra-fast drying and ultra-lightweight functions and are highly effective in maximizing the wicking structure.

[0121] Example 4: PBT (Polybutylene Terephthalate) Elasticity Technician

[0122] PBT is a material that has a structure similar to PET but possesses much higher elastic recovery, allowing for minimal deformation even when forming complex cross-sectional structures such as cross-sectional structures. Since the fiber protrusions are not easily compressed by external pressure, the wicking channels are continuously maintained. This is a significant advantage in terms of anti-wrinkle performance and structural recovery.

[0123] In terms of physical properties, PBT has high elongation and elastic modulus, and the flexibility of the fiber is maintained even in a cross-sectional shape. As a result, the cross-sectional structure can be maintained without distortion during weaving or knitting, allowing for the stable formation of a capillary structure.

[0124] Chemically, PBT has very low moisture absorption and excellent heat and chemical resistance, resulting in minimal structural damage from sweat or contaminants. This greatly helps maintain stable fabric performance when functional clothing is used in various environments.

[0125] In terms of spinning efficiency, the low shrinkage rate of PBT is a significant advantage. While uneven fiber tension during the spinning process can easily disrupt the cross-sectional structure, PBT maintains uniform tension, allowing for the continuous formation of a cross-sectional structure without disruption.

[0126] PBT-based fibers exhibit excellent resilience, structural stability, and wicking continuity, making them an optimal material for high-performance sportswear and high-elasticity stretch fabrics.

[0127] Example 5: PET-Nylon composite structure copolymer fiber

[0128] Composite fibers manufactured by copolymerizing PET and nylon in a specific ratio can simultaneously utilize the advantages of both materials. By combining the structural stability and cross-sectional formability of PET with the moisture-reducing effect and flexibility of nylon, a composite material can be formed in which the cross-sectional structure is maintained most stably.

[0129] Since the stiffness of PET and the elasticity of nylon are simultaneously exhibited in terms of physical properties, deformation of the cross protrusions and groove structure is minimized even in repetitive environments such as friction, compression, and washing. This provides optimal conditions for maintaining structural precision.

[0130] Chemically, the low moisture absorption of PET and the appropriate hygroscopic properties of nylon are combined to produce wicking characteristics in which the initial absorption rate and sustained diffusion rate operate in balance. This compensates for the shortcomings of existing single materials, which dry too quickly or too slowly.

[0131] In terms of spinning efficiency, the high spinnability of PET helps to precisely control the cross-sectional molding of the copolymer fiber, and the nylon component strengthens the internal bonding of the fiber to maintain the capillary channel forming portion (131) more strongly. The combination of the two materials provides the highest structural stability.

[0132] Consequently, the PET-nylon copolymer material is a top-tier functional fiber possessing composite wicking performance, durability, and structural stability, making it a particularly suitable material for realizing the cross-sectional-based structure of the present invention.

[0133] Another functional fiber can be spun into the helical interlocking structure forming part (132) to improve the functionality of the fabric. Below, five embodiments regarding functional fibers that can be spun together are described.

[0134] Example 1: Antibacterial and antiviral functional fibers

[0135] The antibacterial and antiviral functional fiber is a functional filament in which metal ions or metal nanomaterials, such as silver (Ag), copper (Cu), and zinc (Zn), are introduced on the surface or inside of the fiber. When spun together with the helical interlocking structure forming part (132), the metal ions are continuously exposed to the surface, providing a function that inhibits the proliferation of bacteria and viruses. As a result, the problem of bacterial proliferation caused by increased humidity inside the garment when worn for a long time can be effectively prevented.

[0136] Antimicrobial functional fibers have the effect of inhibiting the survival of microorganisms by allowing metal ions to denature cell membrane proteins or induce the generation of reactive oxygen species (ROS). These chemical reactions are further activated by the internal environment of the garment, such as sweat, moisture, and body temperature, thereby enhancing hygiene. In particular, since the wicking structure facilitates moisture transport, the continuous exposure of metal ions maintains the antibacterial performance.

[0137] In terms of physical properties, antimicrobial filaments manufactured using a dispersion method rather than a surface coating method exhibit high abrasion resistance, ensuring that performance is not easily lost even when coupled with a helical structure. During the spinning process, they are designed to be evenly dispersed within the fiber to prevent metal particles from separating, while the helical structure enhances durability by dispersing external forces.

[0138] In terms of spinning efficiency, the antimicrobial fibers are designed to possess length strength and surface characteristics similar to general synthetic fibers, allowing them to be stably bonded to the helical interlocking structure. The helical structure enables the antimicrobial fibers to be arranged at regular intervals, ensuring that the antimicrobial effect is uniformly manifested throughout the entire fabric.

[0139] As a result, this embodiment combines hygiene and antibacterial capabilities with functional wicking fibers, providing high added value in applications with high sweat production, such as sportswear, functional underwear, and outdoor clothing.

[0140] Example 2: Far-infrared and thermal insulation functional fiber

[0141] Far-infrared functional fibers contain mineral components such as ceramic powder, graphite-based minerals, and tourmaline, and absorb body heat and re-emit it in the form of far-infrared rays to help maintain the body temperature. When such fibers are spun together with a helical interlocking structure forming part (132), the far-infrared ray emission area increases along the repeating pattern of the spiral structure, thereby improving heat retention efficiency.

[0142] In terms of physical properties, far-infrared fibers reduce body heat loss due to their low thermal conductivity and high radiant heat emission performance. The helical structure enhances insulation by effectively trapping external air, and the thermal insulation structure becomes more sophisticated when combined with far-infrared fibers. This presents a significant advantage for functional winter clothing.

[0143] In terms of chemical properties, ceramic powder is resistant to heat and humidity, and there is minimal loss of functionality even during sweating or washing. The helical structure has the effect of maintaining dispersion so that the ceramic functional particles do not clump together, and enables uniform functional expression even during the spinning process.

[0144] In terms of spinning efficiency, far-infrared fibers possess rigidity, which enhances structural stability when combined with a helical structure. The helical structure arranges functional filaments at regular intervals, ensuring that thermal insulation performance is uniformly distributed throughout the entire fabric.

[0145] This embodiment produces a significant synergy effect in product categories requiring both thermal insulation and walking functions, such as winter sportswear, hiking wear, and thermal underwear.

[0146] Example 3: Cooling and heat transfer functional fiber (Cool Fiber)

[0147] The cooling functional fiber is a fiber designed with a polymer structure that contains mineral components with high thermal conductivity (e.g., jade powder, Quick Cool Mineral) or has a contact cooling function. When such a fiber is spun together with a helical interlocking structure forming part (132), the helical structure finely disperses the contact area with the skin, enabling rapid heat transfer and providing an excellent cooling effect.

[0148] The physical characteristic of cooling fibers lies in their ability to rapidly establish temperature equilibrium, allowing body heat to quickly move into the filaments and disperse. Structurally, the helical structure creates a complex surface area, ensuring that the cooling function is uniformly reflected throughout the entire fabric.

[0149] In terms of chemical properties, the cooling filament exhibits a characteristic where the heat transfer rate increases when exposed to moisture, and when combined with the wicking function, it rapidly dissipates heat accumulation caused by sweat. A structural synergy effect occurs in which the cooling function and the moisture transport function mutually amplify each other.

[0150] In terms of spinning efficiency, cooling fibers have a spinning process similar to general synthetic fibers, so they are stably bound even when entangled with a helical structure. The helical arrangement provides various heat conduction paths, improving the ability to dissipate body heat.

[0151] This functional fabric provides excellent cooling-drying performance when applied to summer sportswear, running wear, training clothing, etc., and is very advantageous in high-performance fields where sweat and heat must be removed quickly at the same time.

[0152] Example 4: Antistatic Functional Fiber (Conductive Fiber)

[0153] The antistatic functional fiber is composed of filaments containing carbon fiber, stainless steel fiber, copper fiber, or a conductive polymer. When this fiber is spun together with a helical interlocking structure forming part (132), the helical structure continuously forms a conductive path in the longitudinal direction, effectively discharging accumulated static electricity.

[0154] In terms of physical properties, conductive fibers have low resistance along their length, and when combined with a helical structure, the spiral structure provides multiple discharge paths, thereby increasing the speed of static electricity removal. This effectively resolves static electricity issues in clothing during winter or in dry environments.

[0155] In terms of chemical properties, carbon-based fibers maintain conductivity even in extreme environments involving high temperature, humidity, and friction, while stainless steel filaments exhibit excellent corrosion and acid resistance, resulting in minimal functional loss even after long-term use. The helical structure stabilizes the spinning process to ensure the uniform distribution of these functional filaments.

[0156] In terms of spinning efficiency, conductive fibers differ somewhat from general synthetic fibers in their physical properties, so proper tension distribution is required in the helical structure. The helical structure serves to relieve tension, preventing the conductive fibers from breaking.

[0157] Antistatic functional fabrics enhance safety along with wicking capabilities in fields where static electricity management is critical, such as workwear, laboratory clothing, industrial textiles, and clothing for handling electronic devices.

[0158] Example 5: Antibacterial, Deodorizing, and Anion-Emitting Composite Functional Fiber

[0159] Functional fibers that provide antibacterial, deodorizing, and negative ion functions are composed of filaments containing zeolite, activated carbon, tourmaline, ceramic powder, etc. When spun together with a helical interlocking structure forming part (132), the helical structure increases the exposed surface area of ​​the composite functional particles, thereby maximizing the antibacterial and deodorizing effects.

[0160] In terms of physical properties, activated carbon and zeolite-based fibers possess a porous structure that adsorbs odor-causing substances, organic compounds, and bacterial growth molecules, thereby exhibiting a deodorizing effect. The helical structure forms an air layer, further accelerating the rate of adsorption and deodorization.

[0161] In terms of chemical properties, tourmaline and ceramic materials emit negative ions, providing a function that enhances wearer comfort and reduces skin stress. When combined with a wicking function, they contribute to relieving mild static electricity and discomfort in the body.

[0162] In terms of spinning efficiency, this composite functional fiber requires dispersion stabilization, and the helical structure solves the problem of composite particles shifting to one side during spinning. The helical arrangement distributes the composite particles uniformly and maintains the function uniformly throughout the fabric.

[0163] This embodiment can be usefully applied to functional wear, outdoor clothing, functional underwear, long-wear clothing, etc., by simultaneously enhancing comfort, deodorization, and antibacterial functions.

[0164] As explained above, the present invention overcomes the limitations of simple cross-sectional structures found in the prior art by forming the fiber cross-section into a cross-sectional structure. While conventional circular cross-sectional fibers had the problem of slow moisture movement due to limited capillary formation, the cross-sectional structure according to the present invention provides continuous and three-dimensional grooves and edges on the fiber surface, thereby promoting natural moisture absorption and movement. This has the advantage of not relying on separate chemical processing, as it can maximize the wicking effect solely through the basic structure of the fiber itself.

[0165] Furthermore, the radial extensions presented in this invention narrow toward the ends and form a rounded shape, preventing the problem of sweat flow being interrupted or stagnating as it moves along the fibers. This structural continuity fundamentally improves the localized moisture stagnation commonly occurring in conventional fibers and enables moisture to diffuse more quickly and uniformly. As a result, sweat from the body surface is absorbed into the fabric more rapidly, significantly reducing initial discomfort.

[0166] The present invention solves the problem of irregular capillary paths that occurred in conventional spun yarns through a capillary channel forming portion that is naturally formed when a plurality of fibers are combined during spinning. Conventional fiber yarns frequently experienced the phenomenon where the moisture transport passage was interrupted or became excessively narrow due to the random arrangement of fibers, but the structure of the present invention stabilizes capillary formation by maintaining a continuous path in a form where grooves and edges interlock with each other. This allows moisture to continuously move inward toward the interior of the fiber yarn.

[0167] Furthermore, the helical interlocking structure forming part provided in the present invention has the effect of simultaneously improving the bonding strength between fibers and capillary formation. Conventional fibers have a problem in that their structure is easily deformed by external impact or repeated use because they are loosely bonded to each other. In the helical structure, screw-thread-shaped grooves interlock to stably bind the fibers, and the spiral micro-channels formed in this process provide another capillary network for moisture transport.

[0168] The structure of the present invention provides enhanced performance not only in the moisture absorption stage but also in the evaporation stage. Moisture absorbed into the fibers through a continuous capillary structure rapidly diffuses across the wide surface of the fabric, and the evaporation rate increases as the surface area in contact with air expands. The "dampness that persists for a long time after moisture saturation," which was pointed out as a problem in the prior art, is significantly alleviated in the present invention, allowing the user to maintain comfort even during prolonged activities.

[0169] Furthermore, the present invention possesses structural durability that maintains performance even after prolonged use and repeated washing. Conventional moisture-wicking and quick-drying performances mostly relied on surface coatings or chemical processing, which suffered from performance degradation over time. However, because the present invention implements these functions based on the inherent cross-sectional structure of the fiber itself and the interlocking structure between fibers, performance persists regardless of damage to the external processing layer. This offers a significant advantage in fields where maintaining continuous performance is critical, such as functional clothing, sportswear, and workwear.

[0170] In summary, the present invention solves the problems of conventional technology, such as slow moisture absorption speed, irregular capillary structure, low evaporation efficiency, and performance degradation during long-term use, through fundamental improvements to the fiber cross-sectional structure and fiber yarn binding method. The fiber fabric according to the present invention stably implements a series of flows that rapidly absorb, move, diffuse, and evaporate sweat, and can be utilized as a functional fabric that maximizes the comfort of the wearer.

[0171] The above detailed description of the present invention describes only specific embodiments thereof. However, it should be understood that the present invention is not limited to the specific forms mentioned in the detailed description, but rather should be understood to include all variations, equivalents, and substitutions within the spirit and scope of the invention as defined by the appended claims.

[0172] In other words, the present invention is not limited to the specific embodiments and descriptions described above, and any person skilled in the art to which the present invention pertains can make various modifications without departing from the essence of the invention as claimed in the claims, and such modifications fall within the scope of protection of the present invention.
