Description

Technical Field

[0001] The utility model relates to a knitting structure of clothing fabrics, in particular to a knitting structure of fabrics used for producing sportswear, outdoor clothing and peripheral products. Background Art

[0002] The functionality of sportswear, outdoor clothing and peripheral products has become an important factor for consumers to choose and evaluate. For professional sports or outdoor enthusiasts, the selection elements usually include the following aspects: tactile performance, moisture absorption and wicking performance, and thermal performance. The tactile performance is evaluated by the relevant performance of the clothing in contact with the skin, for example, evaluated from aspects such as materials, tensile, bending, shear, and compression capabilities. After a large amount of exercise, the sweating and heat generation of the exerciser's body increase, and there will be a periodic pulsating sweating phenomenon on the body surface. The clothing worn must quickly discharge sweat and keep the clothing surface as dry as possible. The moisture absorption, moisture permeability, heat insulation and other indicators of the clothing have become further measurement indicators for most consumers, and thus have become the mainstream direction pursued by most sportswear or outdoor clothing manufacturing enterprises. For the thermal performance of sportswear or outdoor clothing, it is another trend pursued by the market and consumers in recent years. Heat dissipation is the process of heat transfer from the body surface maintained at a certain temperature to the external environment with a lower temperature, and is the combination of heat conduction, heat convection and heat radiation. Manufacturing enterprises have continuously developed various new materials from the perspective of clothing fabrics, expecting to quickly dissipate heat during exercise, or even generate a cool feeling on the skin surface, so that the exerciser can achieve a comfortable body feeling, thereby improving the heat dissipation of sportswear.

[0003] However, the evaluation of the thermal performance of sports or outdoor clothing requires more than just heat dissipation; it also needs to consider thermal insulation and even thermal energy storage. Sweating is one of the primary mechanisms for heat dissipation; when sweat evaporates from the skin's surface, it removes heat and lowers body temperature. In hot environments, athletes lose 1.5 to 2.5 liters of sweat per hour during strenuous exercise, along with a significant amount of electrolytes. Sweat is primarily composed of water, accounting for 98 to 99%. The specific gravity of sweat ranges from approximately 1.002 to 1.003, with a pH of 4.2 to 7.5. In addition to water, sweat primarily contains urea, lactic acid, glucose, uric acid, creatine, creatinine, amino acids, and electrolytes such as sodium ions, potassium ions, calcium ions, magnesium ions, chloride ions, and inorganic phosphorus. Of these, 1 to 2% is a small amount of urea, lactic acid, and fatty acids. The osmotic pressure of sweat is lower than that of plasma. During exercise, athletes produce large amounts of sweat, often losing more water than salt, leading to hypertonic dehydration. However, after replenishing sufficient water, insufficient salt levels can cause a decrease in plasma osmotic pressure, leading to hypotonic dehydration. This excessive sweating rapidly causes the athlete's body temperature to drop, resulting in a transient decrease in surface temperature. The combined effects of these factors can cause discomfort after exercise, even leading to low blood pressure, cold hands and feet, or shock. Therefore, when evaluating the thermal performance of outdoor clothing, simply considering heat dissipation is somewhat one-sided. It is necessary to consider the actual conditions encountered when wearing sportswear or outdoor clothing, taking into account thermal energy storage capacity as a key evaluation metric. This is a commonly overlooked issue in the research and development of sportswear and outdoor clothing.

[0004] There has been some interest in and research on improving the thermal insulation performance of sportswear in the prior art, with most addressing the issue from the perspective of material development. For example, Primaloft cotton (P cotton), a chemical fiber cotton with a short hollow fiber structure, Thinsulate cotton developed by 3M, and G-loft softshell pioneer G cotton, all focus on thermal insulation performance, developing fabrics and materials themselves. However, the background of these developments is to find new thermal insulation fabrics for colder natural environments. A large number of integrated technologies have also emerged in the prior art, such as adding coatings or fiber surfaces to existing fabrics to absorb sweat while achieving thermal insulation and sterilization. However, most of these new fabrics or coated fabrics do not consider the heat energy storage required by athletes after exercise due to sweating and the subsequent instantaneous drop in body temperature caused by sweating. In most cases, these new fabrics or coated fabrics cannot be used as underwear fabrics for sportswear that is close to the skin. Moreover, adding coatings or fibers to the fabric surface often sacrifices comfort, making them generally unsuitable for use as inner layer sportswear or outdoor clothing. Utility Model Content

[0005] The purpose of the present utility model is to provide a novel knitting structure, which not only achieves a better sweat-discharging and heat-dissipating effect during exercise, but also can timely keep warm and store thermal energy when the body has a cold feeling after sweating, so as to avoid physical energy loss caused by hypothermia. For this reason, the present utility model proposes the following technical solutions, among which:

[0030] To make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with specific embodiments of the present invention and the corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] Although the specification of the present invention may include various different forms of embodiments, for some preferred embodiments described in detail in the specification and shown in the drawings, it should be understood that: the content disclosed in the specification of the present invention should be regarded as a schematic illustration of the principles of the present invention, and these shown embodiments are not intended to limit the scope to be protected by the present invention.

[0032] According to the standard of GB / T24254-2009 Determination of the Required Thermal Resistance of Textiles and Clothing in Cold Environments, the factors determining human thermal balance are mainly three aspects: clothing thermal resistance, body heat generation, and environmental physical characteristics. Clothing thermal resistance is related to factors such as textile fiber properties, yarn specifications, fabric structure, clothing structure, style, number of layers, looseness, type and quality of filling materials, etc.

[0033] Since 2002, the applicant has been consistently committed to the research and development in the field of improving the heat storage capacity of sportswear, outdoor clothing and related products, and has developed several generations of core patented technologies of TSIE (Turn Sweat Into Energy). For example, CN1561170A discloses that the yarn facing the skin has a completely closed and smooth surface and is of an integral structure. The yarn facing the skin is made of many single strands of fiber, which are combined into one fiber and have a closed and smooth surface. Yarn 2 is basically made of single strands of fiber. Yarn 2 is basically inelastic and is woven with Yarn 1. Here, a "curled" surface is formed. In addition, CN102481024A discloses a three-dimensional fabric, which on the one hand provides the possibility of generating air bags that can prevent cooling after exercise; the fabric provides insulation to avoid cooling after physical exercise. Turning sweat into energy is the R & D concept that the applicant has always adhered to and explored and implemented. With this as the core, a complete technical development route has been formed. Based on the existing patented technologies, the applicant continues to improve and refine them. In the iterative technologies, the changes in body temperature during exercise are fully considered, and the knitting structure of the fabric is deeply improved. The trend of body temperature change is fully combined with the improvement of the knitting structure, and then the unique knitting structure acts on the human body itself, making an effective contribution to the heat storage of the human body.

[0034] As mentioned above, the purpose proposed by the inventive concept of the present utility model is to solve the problem that when a sports person sweats after a large amount of exercise and the body temperature drops, a part of the sweat can be converted into the heat energy required by the body, and when feeling cold, it can provide effective heat energy for the body.

[0035] The following will, with reference to the accompanying drawings, elaborate on the technical solutions provided by each embodiment of the present utility model.

[0036] To this end, the present utility model provides a novel knitting structure, which can be used for inner sportswear, such as underwear, skin-friendly upper garments, skin-friendly lower trousers, etc., and can also be used for other products in contact with the skin surface, such as hats, socks, gloves, protective masks, etc. Most of the clothing or other products to which the present utility model is applied are knitted products. On the premise of not violating the inventive concept of the present utility model, corresponding embodiments can also be made of other fabrics or materials. This kind of knitting structure has independent knitting units. When specifically applied, the knitting units can be arranged differently according to the set positions to form a shape that conforms to ergonomics and has aesthetic feeling. Figure 1As a cross-sectional view after continuous tiled arrangement of the knitting units, it shows the basic concept of the present utility model. It can be seen that each knitting unit includes multiple evaporation channels 10 and multiple air channels 20. Among them, each evaporation channel 10 and each air channel 20 are adjacent and arranged at intervals, and the two are continuously and coherently arranged. The evaporation channel 10 has a top wall 11, and its bottom has a first open structure with an opening downward. The bottom surface 12 of the evaporation channel 10 is used to contact the skin; the top of the air channel 20 has a second open structure with an opening upward. This second open structure includes an opening 21 and an air chamber 22 formed by smoothly extending downward from the opening 21. The cross-sectional diameter of the bottom of the air chamber 22, that is, the bottom wall 24 of the air chamber, is larger than the cross-sectional diameter of the opening 21. Thus, the first open structure with an opening downward and the second open structure with an opening upward are also arranged at intervals and coherently.

[0037] The evaporation channel 10 serves as a discharge and dissipation channel for sweat 100, forming a continuous and through cavity to guide the sweat away from the skin surface and reduce the humid and sticky feeling on the body surface. Therefore, the evaporation channel 10 has a raised structure compared to other areas, and can form an effective sweat export pipeline or path. In order to achieve an ideal effect in the link of sweat export, a plurality of air holes 111 are laid flat on the top wall 11 of the evaporation channel 10. As Figure 2 shown, the air holes 111 can be arranged continuously along the longitudinal extension line of the top wall 11, or can be arranged at intervals horizontally parallel at regular intervals. The air holes 111 are preferably arranged on the outer surface of the top wall of the evaporation channel 10 to better achieve the effects of sweating and dissipating heat and humidity.

[0038] When evaluating the heat energy storage capacity of outdoor inner-layer clothing, it is necessary to consider the destructive effect of the clothing wetting state on the heat energy storage capacity. Because for the clothing wetted by sweat, the gaps between the fibers will be filled with sweat, and the thermal conductivity of water (the theoretical value is 0.599) is much greater than the thermal conductivity of air (the theoretical value is 0.026), resulting in a significant reduction in the thermal insulation performance of the clothing. If a dry and static air layer can be set on the inner-layer clothing close to the body, the situation of the reduced heat storage capacity of the clothing after being wetted by sweat can be avoided. For a better sweating and heat dissipation effect, another embodiment of the present utility model provides a diversion component with a "funnel structure", that is, a sweat discharge channel. Specifically, as Figure 3As shown in the figure, the diversion component is structured as follows: a hat-shaped disk body 112 is provided below the air hole 111, and the two are connected through an air tube body 113. The air hole 111, the disk body 112, and the air tube body 113 are all hollow structures, and their interiors communicate with each other. The cross-section of the upper port of the air tube body 113 constitutes the air hole 111. The bottom of the disk body 112 faces the bottom surface 12 of the evaporation cavity 10, that is, towards the skin surface. When the sweat 100 evaporates from the skin surface, it first passes through the disk body 112. Obviously, the cross-section of the disk body 112 is larger than that of the air tube body 113 and the air hole 111. When the sweat or moisture continues to pass through the air tube body 113 and the air hole 111, the flow rate will increase, and the sweat will be discharged out of the body faster and away from the body surface. In particular, when the amount of sweat is large, the knitted yarns of the disk body 112 will swell and open wider, and when the sweat decreases, the disk body 112, the air tube body 113, and even the air hole 111 will shrink and close. That is to say, the described funnel structure has the effect of "dry closing and wet opening", which can not only accelerate the discharge of sweat but also prevent the reverse osmosis of sweat. The purpose of this implementation is considered as follows: Although means have been made as much as possible to discharge sweat from the body surface as soon as possible, there will still inevitably be a small amount of sweat 100 remaining on the inner surface of the evaporation cavity 10. At this time, the body temperature of the exerciser is decreasing as the sweat flows out. Through the concept of the present invention, the relatively static air with a certain temperature formed by the remaining sweat 100 in the evaporation cavity 10 can be utilized to convert it into the heat necessary for the exerciser to maintain physical strength. In some preferred embodiments, the cross-section of the upper port of the air hole 111 constitutes a part of the fabric surface, while the disk body 112 and the air tube body 113 are both arranged below the fabric surface, that is, the inner layer of the fabric that can contact the skin surface.

[0039] The discharge and heat dissipation of sweat are issues that are generally emphasized and concerned in the prior art. And how to maintain the necessary thermal energy when the body temperature drops or even hypothermia occurs after the sweat is discharged, so that the exerciser will not feel overly cold and effectively ensure physical strength, is the technical problem concerned by the present utility model.

[0040] Refer to Figure 1 and Figures 4 - 5, according to the concept of the present utility model, continuous evaporation channels 10 and air channels 20 are provided on the surface of the clothing in contact with the skin. The air channel 20 has an opening with an open structure, including an opening 21 and an air chamber 22 smoothly extending downward from the opening 21. The bottom of the air chamber 22 has an air chamber bottom wall 24, which is in contact with the skin surface. A common side wall 23 exists between two adjacent evaporation channels and air channels. As can be seen from the drawings, the cross-sectional diameter of the air chamber bottom wall 24 is larger than that of the opening 21. Such a sac-like structure design is to accommodate more external air 200. When the exerciser sweats a lot, part of the sweat is first discharged from the body surface through the evaporation channel 10. In addition, another part of the sweat and moisture are discharged through the air chamber bottom wall 24 of the air channel 20 and are continuously replaced by fresh air entering from the outside. When the sweat is discharged from the body surface, the body surface temperature of the exerciser will decrease, and a wet and cold feeling will be generated due to the sweat staying on the clothing surface. Especially after relatively intense exercise, due to excessive sweating, there will be a risk of hypotonic dehydration reaction, which will further lead to hypertonic dehydration, and further lead to risks such as low blood pressure and even shock. At this time, it is particularly important to maintain the due heat energy. According to the embodiment of the present utility model, after the sweating ends and the body temperature of the exerciser decreases, a large amount of air is stored in the air channel 20 because no more sweat is generated, resulting in the interruption of the temperature drop in the cavity at this place. Because a large amount of air is stored here, the temperature is maintained in a relatively constant state. In addition, the remaining sweat 100 and the warm air formed by the heat and moisture in the original evaporation channel 10 will also stay inside the evaporation channel 10 and circulate (as shown by the arrows in Figure 1 and Figure 5 . Especially in the case where there are air holes 111, a disc body 112, and a trachea body 113, factors such as the decrease in the body surface temperature of the exerciser and the discharge of sweat cause this part of the structure to close, thereby realizing the basic heat preservation function.

[0041] In the existing known technical solutions, there is no effective solution to how to effectively store more air in the inner layer of the close-fitting sports clothing and how to utilize a part of the remaining sweat to store energy. However, through the implementation mode of the present utility model, significant improvements have been made in similar problems.

[0042] The heat conduction of fibers is partly through the convection transfer of the air contained in the material and partly through the radiation transfer between fibers. For knitted fabrics, there is a large amount of air in the gaps between yarns, and the air content per unit area of the fabric is generally 50-60%. The thermal conductivity of still air is very small and can be regarded as the best thermal insulator and heat preservation medium. Therefore, the more air the knitted fabric retains, the better the thermal energy storage performance of the clothing. In addition, it cannot be ignored that the wettability of the clothing also has a great impact on the heat preservation performance. The thermal conductivity of water is much greater than that of air. When the clothing is in a wet state, the heat preservation performance will be greatly reduced.

[0043] When the clothing is in close contact with the wearer's body, theoretically the thickness of the air layer is zero and the heat preservation is the least. To solve the above technical problems, in the preferred embodiment of the present utility model, it is expected to effectively set an air layer at specific parts of the inner layer of outdoor clothing close to the body, improve the fabric fluffiness, reduce air circulation, and reduce heat conduction, so as to improve the thermal energy storage capacity and achieve a good heat preservation effect. However, when the thickness of the air layer exceeds a certain value and continues to increase, because the convection effect of the air is increased, the heat loss will increase and the heat preservation performance will decrease at any time. Considering this trend, the side wall 23 can be divided into an upper side wall 231 and a lower side wall 232. During the knitting process, the knitting density of the upper side wall 231 is increased and is greater than the knitting density or the degree of density of the lower side wall 232, that is, the density of the material used for the upper side wall 231 is greater than the density of the material used for the lower side wall 232. For example, when the transverse density P A (the number of wales within the specified length in the course direction of the fabric loop) remains unchanged, when the longitudinal density P B (the number of courses within the specified length in the wale direction of the fabric loop) of the lower side wall 232 is 40-45, the longitudinal density P B of the upper side wall 231 is 55-60, and the total density of the upper side wall 231 (that is, the P A *P B value) is increased by 37-55% compared with the lower side wall 232. Of course, it can also be appropriately adjusted according to the physical and chemical properties of the yarn. However, according to the general properties of different materials, such as combed yarns, wool blends, etc., the total density of the upper side wall 231, especially the longitudinal density P B is greater than the longitudinal density P BWhen it is 40 - 45%, the air channels 20 can achieve good airtight performance. At the same time, the overall height range of the side wall 23 is between 2.5 - 6 mm. When it exceeds 8 mm, the heat energy storage capacity will instead decrease. When the exerciser feels the body temperature drop due to sweating, the exerciser can apply force in the area where this knitting structure is arranged. For example, gently grasping with the hand can fill the air channels 20 in this area with air, increasing the air retention amount, and the heat energy storage effect will be better. In addition, through applying force, structures such as pores at the evaporation channels 10 can also be more effectively closed, and the warm gas retained in the evaporation channels 10 can provide better basic heat preservation. Tests have shown that under the conditions of a normal temperature of 21°C, a relative humidity of 45%, and an air flow of 10 cm / s, after the tester's activity, the metabolic level reaches 3 Met (moderate activity state, such as jogging, climbing a mountain at a constant speed, etc.). When testing the test knitted fabric made of warm cotton yarn with this knitting structure, the clo value per unit reaches 0.83 Clo / OZ; while the clo value obtained from testing the same material knitted fabric without this knitting structure is 0.68 Clo / OZ, and the clo value has increased by 22% (The fixed value method for 1 thermal insulation unit (1 Clo): In an environment with a room temperature of 21°C, a relative humidity not exceeding 50%, an air flow rate not exceeding 10 cm / s, the wearer feels comfortable, and the body surface temperature is maintained at 33°C, the thermal insulation value of the clothing worn is set as 1 Clo. The clo value of cotton is 0.04 Clo / OZ; the clo value of Merino wool is 0.08 Clo / OZ; the clo value of Primaloft cotton (P cotton) is 0.90 clo / oz, the clo value of Thinsulate cotton developed by 3M Company is 0.84 clo / oz, and the clo value of G-loft soft shell pioneer material G cotton is 0.92 clo / oz).

[0044] It should be noted here that in a highly active state such as during sports or outdoor activities, the requirement for the heat preservation value of clothing is relatively not too high. Especially considering the characteristics of sports or outdoor activities, it is necessary to first discharge sweat and then store heat energy to prevent adverse consequences caused by an instantaneous drop in body temperature. For example, through ANSI / ISEA201 - 2012 "Classification of Warm Clothing in Cold Environments", it can be known that according to the determination result of the heat preservation value (measurement unit: clo value), the applicable cold-resistant temperature range of clothing is determined as shown in the following table. Among them, 2 Met is light activity, such as walking, simple housework, regular driving and other light activity operations; 4 Met is high activity, such as violent excavation, fast-paced mountain climbing, competitive running and other intense sports. In a highly active state, the required heat preservation value of clothing is relatively low:

[0045]

[0046] Table 1: Determination of the applicable cold-resistant temperature range of clothing based on the heat preservation value determination result

[0047] To achieve better thermal energy storage effect, as Figure 5 shown, there is remaining sweat 100 inside the evaporation channel 10 and it circulates inside (as Figure 5 indicated by the arrow in

[0048] In some preferred embodiments, when weaving the air chamber bottom wall 24 of the air channel 20, a "funnel structure" can also be set. Different from the way and purpose of setting in the evaporation channel 10, as Figure 6 shown, this structure only includes several chassis 25 arranged on the air chamber bottom wall 24, and each chassis 25 extends upward to form an expanding cavity body 26. When sweat evaporates from the skin surface, the temperature and humidity on the surface of the woven structure will rise with the increase of body temperature. Through the chassis 25 of the air channel 20, the woven material here is selected as infrared-sensitive yarn. Therefore, by using the changes in temperature and humidity, the expanding cavity body 26 will expand accordingly. During the process of the expanding cavity body 26 getting larger in volume, sweat conduction will form a more active fluid exchange with the outside world, creating a self-regulating mechanism and prerequisite for the expanding cavity body 26 to absorb more fresh air. When the sweat decreases and the body temperature is in a downward trend, the microenvironment on the skin surface changes, and at this time the yarn shrinks accordingly. The air stored in the air channel 20 flows in a vortex or siphon shape towards the inside of the air chamber as the expanding cavity body 26 tightens, ensuring that the air is stably stored inside the air chamber and endowing the woven structure with the ability of autonomous adjustment when worn.

[0049] In addition, in a preferred embodiment, as Figure 6 shown, when weaving the air chamber bottom wall 24 of the air channel 20 close to the skin surface, one or more metal woven wires 241 can be blended in, such as silver wires or copper wires with antibacterial and odor-removing functions, gold yarns with moisture absorption and sweat discharge functions, and other composite fiber materials with improved heat preservation performance, etc. They are blended with the main material through methods such as melt spinning, wire stretching, and bonding coating, and are added to the woven structure by means of single-sided, double-sided, flat knitting, shuttle knitting, full shuttle knitting, etc. to improve the functionality of the clothing.

[0050] To achieve better thermal energy storage effect and at the same time avoid sweat staying on the skin surface for a long time after flowing out and being absorbed by the skin again, in the key areas where this woven structure is provided, for example, as Figure 4As shown, a reverse osmosis layer 27 is continuously provided on the outer surfaces of the evaporation channel 10 and the air channel 20. A reverse osmosis layer 27 can also be added to a part of the outer surface of the air chamber bottom wall 24 of the air channel 20 (i.e., the outer layer surface not in contact with the skin). The reverse osmosis layer 27 has a dry-closed and wet-open membrane surface. When sweat flows out of the body surface, the reverse osmosis layer 27 swells upon encountering the sweat, and the pores of the membrane swell and expand. The micropore diameter after the pores are opened is between 0.8 - 5 nm, which is used for rapid dehydration and desalination of the skin surface. When the sweat is discharged, the membrane surface of the reverse osmosis layer 27 shrinks, and the pores are in an almost closed state. In this implementation, the reverse osmosis layer 27 can be made of a cellulose acetate membrane or an aromatic polyamide membrane, which has good hydrophilic groups, enables a relatively fast water permeation rate, and also has a good desalination rate. The reverse osmosis membrane made of a cellulose acetate membrane or an aromatic polyamide membrane can function under a relatively low operating pressure, has good tolerance to scenarios such as washing and exposure to sunlight, and is less affected by factors such as pH value and temperature. In addition, the reverse osmosis layer 27 can also be a coating layer provided on the surface of a woven structure, such as a carbon layer or a carbon nanotube layer, etc.

[0051] Adopting the concept of the present utility model, different implementation manners can be achieved when applied to a specific woven structure. For example, Figures 7 - 11 as shown, each weaving unit is arranged flatly and continuously.

[0052] Figure 7 This is an application example of one implementation manner of the present utility model, in which the evaporation channel 310 has a lumen structure with surface protrusions, which is used to quickly separate a part of the sweat from the body surface. The air channel 320 is arranged at a position relatively recessed with respect to the evaporation channel 310, which is used to contact the skin surface and at the same time accommodate as much air as possible in the recess.

[0053] Similarly, Figure 8 This is an application example of another implementation manner of the present utility model, in which the evaporation channel 410 has a lumen structure with surface protrusions, which is used to quickly separate a part of the sweat from the body surface. The air channel 420 is arranged at a position relatively recessed with respect to the evaporation channel 410, and its inner surface is used to contact the skin surface and at the same time accommodate as much air as possible in the recess on the outer surface.

[0054] Correspondingly, Figures 9 - 10 This is an application example of yet another implementation manner of the present utility model, in which the evaporation channel 510 has a lumen structure with surface protrusions, which is used to quickly separate a part of the sweat from the body surface. The air channel 520 is arranged at a position relatively recessed with respect to the evaporation channel 510, and its inner surface is used to contact the skin surface and at the same time accommodate as much air as possible in the recess on the outer surface. Figure 10 is Figure 9 a schematic diagram of a specific application example.

[0055] Furthermore,Figure 11 This is an application example of another embodiment of the present utility model. The evaporation channel 610 has a lumen structure with a convex surface, which is used to quickly separate a part of the sweat from the body surface. The air channel 620 is arranged at a position relatively concave with respect to the evaporation channel 610. Its inner surface is used to contact the skin surface, and at the same time, as much air as possible is accommodated in the concave part of the outer surface. A number of air holes 611 are evenly arranged on the surface of the evaporation channel 610, thereby achieving a better effect of sweating and moisture dissipation. Weaving methods such as "picking and roaring" can be selected to form the air holes 611.

[0056] Furthermore, Figure 12 This is an application example of another embodiment of the present utility model. The evaporation channel 710 has a lumen structure with a convex surface, which is used to quickly separate a part of the sweat from the body surface. The air channel 720 is arranged at a position relatively concave with respect to the evaporation channel 710. Its inner surface is used to contact the skin surface, and at the same time, as much air as possible is accommodated in the concave part of the outer surface.

[0057] In addition, the technical solution of the present utility model fully considers the influence of wind speed on sports, especially on sweat management and heat energy conversion during outdoor sports. In the prior art, the thermal conductivity evaluation of outdoor sports clothing is basically carried out under the condition that the air flow is 10 cm / s or less (i.e., no wind). However, during outdoor sports, wind speed is an important factor that cannot be ignored and will greatly affect the heat conduction ability. Research shows that the greater the wind force, the worse the overall warmth retention and moisture resistance of the clothing. Similarly, the movement speed (such as walking speed) will also have a greater impact on the heat conduction ability of the clothing on the body surface. The faster the walking speed, the worse the overall warmth retention and moisture resistance of the clothing. Therefore, in some other embodiments of the present utility model, the weaving units can be designed in a stacked arrangement. At this time, the weaving density of the weaving structure covering the outer layer is greater than that of the weaving structure of the inner layer to adapt to the influence of wind speed on heat energy storage during outdoor sports. The exerciser can choose to install or not install the stacked weaving layer according to actual needs.

[0058] In the weaving process, the evaporation channel 10 is processed by means of rib weaving, jacquard weaving or rib knitting, etc., or woven into a continuous and through convex tube body, etc. The air channel 20 needs to have as large an inwardly concave accommodation space as possible for storing air. For this purpose, when weaving the area of the air channel 20, overfilling weaving can be carried out to form a surplus space, and when weaving the evaporation channel 10, it can be tightened or shortened as much as possible to achieve a continuous and coherent tight pulling effect, so that the sweat on the body surface can achieve better internal circulation.

[0059] This kind of weaving structure can be set in the key sweat management areas. For example, for the upper garment, it can be set on the front chest, back of the neck, armpits, lower back, etc.; for the lower garment, it can be set above the buttocks, knees, inner thighs, etc.

[0060] In addition, a fluff layer can be generated on the fabric surface through post-treatment methods such as sanding, raising, and brushing, so as to enhance the warmth retention of the clothing.

[0061] According to the technical solution disclosed by the present utility model, in the process of sweat management, first, consideration is given to how to quickly discharge sweat and moisture from the body surface. At the same time, the fact that it is impossible to completely drain the sweat staying in the knitted layer of the clothing is objectively faced. When the body surface temperature drops after exercise and the clothing surface inevitably brings a feeling of wet cold, combined with a unique knitting structure, the remaining sweat is actively utilized and converted into necessary heat energy to help the exerciser maintain the necessary physical energy, thereby effectively continuing and implementing the core concept of TSIE (Turn Sweat Into Energy, that is, "convert sweat into energy").
