Description

Technical Field

[0001] The invention belongs to the technical field of heatstroke prevention and cooling clothing, and in particular relates to heatstroke prevention and cooling clothing that can prevent solar radiation. Background Art

[0002] During outdoor work in summer, the temperature in some outdoor areas is as high as 40℃ or above, and the high temperature lasts for a long time around noon. In the outdoor hot environment, the heat in the body of the workers is not only slowly dissipated, but the solar radiation heat from the summer sun will also act on the human body, increasing the heat accumulation in the human body and causing heat stress problems such as heat stroke. About half of the global cases of heat stroke are workers in outdoor hot environments. In work scenarios such as military and police duty, traffic control, construction, take-out food delivery, and express delivery, when air conditioning and other refrigeration equipment cannot be used to cool down, the high temperature environment and solar radiation cause the temperature of the human body's surrounding environment to be higher than 32℃. At this time, the human body cannot maintain temperature balance through its own body temperature regulation, and external measures need to be taken to improve human comfort. The application of cooling clothing is very necessary in outdoor hot environment operations. When sunlight shines on the workers, a large amount of solar radiation heat is absorbed by the cooling material in a short time, thereby significantly shortening the effective cooling time of the cooling clothing. At present, cooling clothing cannot actively reduce its own absorption of solar radiation heat in outdoor hot environments. Therefore, it is very urgent to study a cooling clothing that reduces the absorption of solar radiation heat in outdoor hot environments.

[0003] For example, a Chinese patent application with patent application number 201510761229.1 discloses a heatstroke prevention and cooling clothing, wherein the fabric of the cooling clothing main body includes a supporting layer, a first fabric layer, and a second fabric layer, the cooling module is a water-absorbing resin particle layer arranged between the first fabric layer and the second fabric layer, and the supporting layer is a polyester 3D mesh cloth layer with dual functions of support and breathability. The cooling clothing only needs to be immersed in water for 10-15 minutes, and then dried by hand or by centrifugation in a washing machine for 1-2 minutes to remove the free water in the clothes before use. The cooling clothing does not require refrigeration equipment to cool down, and takes away the heat of the human body through evaporation, and then is filled with water and recycled. The water-absorbing resin particle layer can effectively absorb liquid water and provide sufficient liquid water for evaporation and heat dissipation, thereby reducing the body surface temperature.

[0004] However, in the prior art, only the evaporation of cooling materials is considered to reduce the body temperature. The cooling suit body is combined with breathable fabrics to accelerate the evaporation efficiency. However, in the high temperature outdoor environment, the radiant heat from the sun will greatly shorten the effective cooling time of the cooling suit.

[0005] Based on the above technical problems existing in the prior art, the present invention proposes a heatstroke prevention and cooling clothing that protects against solar radiation. Summary of the invention

DETAILED DESCRIPTION

[0037] In order to more clearly understand the above-mentioned purposes, features and advantages of the present invention, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0038] Example

[0039] As attached Figure 1-3 As shown, the heat-protection and cooling clothing for preventing solar radiation comprises:

[0040] A clothing body 1 and a cooling module 2 fixedly arranged on the clothing body 1, wherein the cooling module 2 comprises a first fabric layer 21 fixedly attached to the clothing body 1, a water-absorbing resin particle layer 22 fixedly attached to the first fabric layer 21, a third fabric layer 23 fixedly attached to the water-absorbing resin particle layer 22, and a second fabric layer 24 fixedly attached to the third fabric layer 23;

[0041] As a specific implementation, the clothing body 1 is made of reflective breathable fabric, for example, the reflective breathable fabric is composed of 87% nylon 6 and 13% spandex, which can effectively reduce the absorption of solar radiation heat; in a test under a simulated daylight xenon light source system, the skin temperature difference between the position covered by the reflective breathable fabric and the position not covered under the same irradiation conditions is as high as 3.5°C, and the fabric has a good effect of reflecting or reducing the absorption of sunlight;

[0042] The reflective breathable fabric used in the clothing body 1 has a gram weight of 179g / m 2 , combined with reflective material transferred to the moisture-absorbing and breathable knitted fabric, the color is white, and it has a cool touch. The reflective breathable fabric not only has the advantages of reflecting light and reducing the absorption of solar radiation heat, but also has the characteristics of breathability and moisture permeability. It can accelerate the evaporation of water absorbed by the cooling module 2 on the basis of reducing the absorption of external solar radiation heat, and take away the heat of the human body;

[0043] like Figure 7 As shown, the reflective breathable fabric includes a reflective layer 11 and a breathable layer 12 bonded to the reflective layer 11, the breathable layer is bonded to the first fabric layer 21, the reflective layer 11 includes a reflective base layer 111 made of spandex and a reflective thread 112 hot-pressed on the reflective base layer 111, and the breathable layer 12 uses cross-section fibers.

[0044] Exemplarily, the cooling module 2 is fixed to the inner side of the clothing body 1 by sewing, the number of the cooling modules 2 is at least two, the number is increased as needed to adapt to different application scenarios, and they are evenly distributed on the front and back parts of the human body;

[0045] Furthermore, the cooling modules 2 are evenly distributed on the front, back, top and sides of the clothing body 1 to achieve cooling of a wider range of the human body;

[0046] The cooling module 2 is set to cool the human body's fever area to improve the cooling effect. An air flow path 3 is provided between adjacent cooling modules 2. The length, width and height of the air flow path 3 are respectively: 20mm×15mm×25mm, so as to ensure that there is enough air circulation space to facilitate air circulation and water evaporation, thereby improving the cooling efficiency;

[0047] The clothing body 1 can be a top, pants, a jumpsuit, a vest, a half-sleeved T-shirt or other styles of clothing.

[0048] The cooling module 2 includes 4 layers, namely the first fabric layer 21 close to the clothing body 1 side, the third fabric layer 23 close to the body side, the water-absorbing resin particle layer 22, and the second fabric layer 24. The first fabric layer 21 close to the clothing body 1 side and the third fabric layer 23 close to the body side are made of the same fabric, and the water-absorbing resin particle layer 22 is wrapped in two parts, front and back. For example, the first fabric layer 21 and the third fabric layer 23 are both made of a blend of 88% nylon and 12% spandex to achieve good water permeability and moisture permeability.

[0049] The water-absorbent resin particle layer 22 is wrapped between the first fabric layer 21 and the third fabric layer 23 to ensure that the phase change cooling material in the water-absorbent resin particle layer 22 does not leak, and the good water permeability and moisture permeability of the first fabric layer 21 and the third fabric layer 23 can ensure that the cooling module 2 is quickly activated during the initial immersion process of the anti-solar radiation and heatstroke cooling clothing described in the embodiment of the present application; the water-absorbent resin particle layer 22 is made of a highly absorbent resin material with antibacterial and anti-mildew treatment. The material has been specially modified, and the free water content after absorbing water is as high as 98%. Heat is taken away through liquid-gas phase change, and each gram of water-absorbent resin particles can absorb about 2430J of heat. In addition, the water-absorbent resin particle layer 22 can repeatedly absorb and release water for more than 60 times, and the effective cooling time can reach more than 4 hours, while maintaining a high water absorption rate and excellent anti-mildew and anti-bacterial properties;

[0050] As a specific implementation method, Figure 4 As shown, the second fabric layer 24 is made of 100% polyester, with a high evaporation rate and good moisture absorption and quick-drying performance. The side of the second fabric layer 24 close to the human skin is a jacquard structure design with a single-sided protrusion 242, which is used to increase the air flow rate in the clothes and increase the air permeability. The surface layer of the second fabric layer 24 close to the human skin is provided with a plurality of fluid flow micro-channels 241. By providing a plurality of interconnected micron-level fluid flow channels on the side close to the human skin, a flow microenvironment in the clothes is formed more quickly to accelerate the evaporation of sweat. Since the channel width of the fluid flow micro-channel 241 is 20nm to 4μm, the fluid is less disturbed during flow, and the flow form is mainly laminar. In the laminar state, there is no obvious mixing and diffusion phenomenon between the layers of the fluid, and the flow velocity is evenly distributed and changes linearly along the flow direction. In addition, the single-sided protrusion 242 structure design of the second fabric layer 24 increases the air permeability and also reduces the dampness in the clothes. After the water-absorbent resin particle layer 22 absorbs water and is dried, the high comfort in the clothes can be quickly maintained.

[0051] The first fabric layer 21 has a gram weight of 91.34 g / m 2 The thickness is 0.22mm, the evaporation rate is high, the thickness and weight are small, the moisture absorption and quick-drying properties are good, and the dampness is low when worn. Therefore, after the water-absorbing resin particle layer 22 absorbs water and is dried, the high comfort of the clothes can be maintained; the fabric weight used in the second fabric layer 24 is 101.6g / m 2 The thickness is 0.40 mm, and the fabric has good hygroscopicity and fast evaporation rate of moisture, and can better absorb human sweat and maintain a dry microenvironment inside the garment. The cooperation of the first fabric layer 21, the third fabric layer 23 and the second fabric layer 24 ensures the overall air permeability and comfort of the garment.

[0052] After multiple tests, the amount of cooling material filled in the water-absorbing resin particle layer 22 in the cooling module 2 was finally determined to be 0.1 g / cm 2 , which can not only ensure cooling efficiency, but also reduce costs and reduce clothing weight;

[0053] The water-absorbing resin particle layer 22 is an antibacterial and anti-mildew water-absorbing resin particle layer that has been treated with antibacterial and anti-mildew treatment;

[0054] like Figure 8 As shown, the water-absorbent resin particle layer 22 includes a first cooling material package 221, a second cooling material package 222 abutting against the first cooling material package 221, and a fiber mesh 223 wrapping the first cooling material package 221 and the second cooling material package 222. The first cooling material package 221 and the second cooling material package 222 are both in the form of fiber-wrapped cooling materials. The use of two relatively independent cooling material packages can significantly extend the service life of the water-absorbent resin particle layer 22. At the same time, the use of two independent cooling material packages allows the water-absorbent resin particle layer 22 to be in block shape without the need for support.

[0055] In actual application, before wearing the anti-solar radiation heatstroke prevention and cooling clothing described in the embodiment of the present application, the anti-solar radiation heatstroke prevention and cooling clothing is pre-soaked in tap water for 10-15 minutes to activate the cooling module 2. After use, it can be spun dry in a washing machine for 3 minutes or the surface moisture can be manually wrung out to remove the free water on the surface of the clothes. The clothes can be used repeatedly, and the effective cooling time can reach more than 4 hours after each activation of the cooling module 2.

[0056] Figure 1The figure shows a schematic diagram of the structure of a universal vest-style solar radiation protection and heatstroke prevention clothing in an embodiment of the present application. The style and structure design concept of the cooling clothing is centered on improving the wearing comfort of the operators without affecting the work and flexibility. The design is based on the certain range of activities of the operators when wearing the cooling clothing. A universal vest-style solar radiation protection and heatstroke prevention clothing is adopted. The clothing style is designed as a universal style for men aged 18 to 60 (170 / 88A). The body is relatively close to the body and the armholes are relatively loose. The region selected is a representative of high temperature and high humidity environment, South China (men aged 18 to 60). Among them, the proportion of men's body types in various regions of China is: A (37.27%)> B (37.04%)> Y (12.34%)> C (11.56%). According to the proportion, select Define body type A, whose chest-waist difference is 16-12cm, height = 170cm, chest circumference = 88cm, the dimensions of various parts of the universal vest-style anti-solar radiation heatstroke cooling clothing are shown in Table 1. Outdoor workers mainly focus on improving work efficiency and reducing labor costs; the armpit area considers work flexibility and comfort, and it is not suitable to set the cooling module 2, and a porous elastic breathable fabric is used to enhance the air flow rate and improve heat dissipation; the shoulder area needs to consider human body mechanics during labor, the load-bearing and wear resistance of the cooling clothing, and it is not suitable to set the cooling module 2; in high temperature and high humidity environments, the form of outward heat dissipation is mostly adopted, so the clothing should be loose and bulky, without a tight feeling; too close will hinder the heat dissipation of the human body, the air layer in the microclimate zone is greater than 1.5-2cm, and the open collar is conducive to accelerating the exchange speed of air from bottom to top in the microclimate zone;

[0058]

[0059] In order to verify the superior technical effect of the anti-solar radiation heatstroke and cooling clothing described in the embodiment of the present application, a specific warm-body manikin is set to test the anti-solar radiation heatstroke and cooling clothing described in the embodiment of the present application, wherein the warm-body manikin is composed of 34 independently controlled thermal zones, all of which are equipped with heaters to simulate the metabolic heat output rate, and the skin temperature is measured using a distributed line sensor. In addition, the warm-body manikin can be controlled to have a constant segmental skin temperature in a constant skin temperature mode, or a fixed segmental heating power in a constant heating power or heating flux mode; the heating power of the warm-body manikin when wearing the cooling clothing is tested in a climate room by using a warm-body manikin, and the segmented heating power of the warm-body manikin is recorded on a computer every minute using the ThermDAC control software. In the embodiment of the present application, a dry warm-body manikin wearing a cooling clothing in a constant skin temperature mode is used to compare and evaluate the heating power. After wearing the cooling clothing in the constant skin temperature mode, the heating power of the manikin will change. In order to maintain a constant temperature, the heating power of the area where the manikin wears the cooling clothing will increase, so as to compare the heating power of the covered section and the uncovered section of the manikin's cooling clothing. Figure 5 The heating power changes of the dummy after wearing the cooling suit. The average heating power of the cooling suit covered area is 82.99W / m 2 The average heating power is significantly higher than that of the uncovered area, which is 38.05W / m 2 The maximum heating power in the first 20 minutes can reach 250-260W / m 2 , indicating that the cooling suit has a good cooling effect;

[0060] The experiment lasted for 2 hours. The average heating power of the manikin was 110.07 W / m 2 The average heating power of the manikin in the last hour is 61.51W / m 2 , the initial cooling should not be too fast, and the human body is cooled at a steady speed to create a comfortable temperature inside the clothing without the stimulation of excessive cooling, while maintaining a high cooling effect, adjusting the clothing environment of outdoor workers, and as the cooling time increases, the cooling rate of the anti-sun radiation heatstroke prevention and cooling clothing described in the embodiment of the present application can still maintain a high cooling effect in the later stage, indicating that the cooling clothing can maintain a long cooling time, prolong the comfortable micro-environment time inside the clothing, and maintain human comfort. Therefore, the cooling effect of the anti-sun radiation heatstroke prevention and cooling clothing described in the embodiment of the present application is relatively excellent;

[0061] The temperature and humidity of the artificial climate chamber were set to the common outdoor working environment conditions with a wind speed of 2.5 m / s and a solar radiation of 600 W / m 2 , the temperature is 35°C, the relative humidity is 50%, in the experimental environment, the thermal manikin is wearing the anti-solar radiation heatstroke and cooling clothing described in the embodiment of the present application, and the skin temperature experiment of the dry thermal manikin is performed based on the constant power mode, such as Figure 6 As shown, Figure 6 Part a in the middle is heatstroke prevention and cooling clothing that is not protected from solar radiation. Figure 6 Part b is the heatstroke-proof and cooling clothing for preventing solar radiation as described in the embodiment of the present application. The test results are as follows: compared with the three cooling areas covered by the heatstroke-proof and cooling clothing without solar radiation protection, the temperatures of the shoulders, stomach and waist are significantly higher than those of the three cooling areas of the heatstroke-proof and cooling clothing for preventing solar radiation as described in the embodiment of the present application. The difference in the maximum temperatures between the two is 2 to 3°C. It can be seen that the heatstroke-proof and cooling clothing for preventing solar radiation as described in the embodiment of the present application can block the heat of solar radiation and has a significant cooling effect.

[0062] Comparing the temperature change trends of the three cooling areas of shoulders, stomach, and waist covered by the heatstroke prevention and cooling clothing without solar radiation protection and the heatstroke prevention and cooling clothing with solar radiation protection described in the embodiment of the present application, the temperature inside the heatstroke prevention and cooling clothing without solar radiation protection is slightly higher than the heatstroke prevention and cooling clothing with solar radiation protection described in the embodiment of the present application, and there is an obvious upward trend, but the temperature inside and outside the heatstroke prevention and cooling clothing with solar radiation protection described in the embodiment of the present application remains stable, without an upward trend, indicating that the heatstroke prevention and cooling clothing with solar radiation protection described in the embodiment of the present application can effectively block the heat of solar radiation and maintain its own temperature stable. , reduce the absorption of external heat; the time from the cooling effect of the cooling suit to the cooling effect disappearance is the effective cooling time, and the cooling effect is lost when the average temperature of the whole body exceeds 34°C. The longer the effective cooling time, the better the cooling effect. The effective cooling time of the heatstroke-proof cooling suit without solar radiation protection during the 2h experimental time is 63min, which is much lower than the effective cooling time of 104min of the heatstroke-proof cooling suit with solar radiation protection described in the embodiment of the present application. Therefore, the heatstroke-proof cooling suit with solar radiation protection described in the embodiment of the present application maintains the cooling effect for a long time and can provide a longer comfortable environment time inside the clothes for the human body;

[0063] At solar radiation of 400W / m 2 , under the environment of 35℃, 50% relative humidity and 0.4m / s wind speed, the surface temperature change test of the warm manikin and the evaporation test of the cooling suit were carried out on the wearer wearing the anti-solar radiation heatstroke cooling suit described in the embodiment of the present application. The test results are as follows: before and after 2h of the experiment, the evaporation was 246.86g, the average temperature of the warm manikin was 36.01±0.99℃, the shoulder temperature was 34.99±1.57℃, the stomach temperature was 32.34±0.42℃, and the waist temperature was 31.45±0.7℃. By calculating that the effective cooling time that can be achieved by the cooling amplitude in the 2h experiment is 120min, it can be seen that the temperature of the shoulders, stomach and waist covered by the cooling suit is much lower than the overall average temperature, and the effective cooling time exceeds 1h, and the cooling suit has a significant cooling effect;

[0064] At solar radiation of 600W / m 2, under the environment of 35℃, 50% relative humidity and 0.4m / s wind speed, the surface temperature change test of the warm manikin and the evaporation test of the cooling suit were carried out on the wearer wearing the anti-solar radiation heatstroke cooling suit described in the embodiment of the present application. The test results are as follows: before and after 2h of the experiment, the evaporation was 307.71g, the average temperature of the warm manikin was 38.6±2.01℃, the shoulder temperature was 38.01±2.61℃, the stomach temperature was 33.79±0.73℃, and the waist temperature was 32.64±0.49℃. By calculating that the effective cooling time that can be achieved by the cooling amplitude in the 2h experiment is 89min, it can be seen that the temperature of the stomach and waist covered by the cooling suit is much lower than the overall average temperature, and the effective cooling time exceeds 1h, and the cooling suit has a significant cooling effect;

[0065] At solar radiation of 800W / m 2 In an environment with an ambient temperature of 35°C, a relative humidity of 50%, and a wind speed of 0.4m / s, a surface temperature change test of a warm manikin and an evaporation test of the cooling suit were conducted on a person wearing the anti-solar radiation heatstroke cooling suit described in the embodiment of the present application. The test results are as follows: before and after 2h of the experiment, the evaporation amount was 324.27g, the average temperature of the warm manikin was 41.23±2.64°C, the shoulder temperature was 41.08±3.55°C, the stomach temperature was 35.23±0.99°C, and the waist temperature was 34.14±0.6°C. By calculating that the effective cooling time that can be achieved by this cooling amplitude in a 2h experiment is 65min, it can be seen that the temperatures of the stomach and waist covered by the cooling suit are much lower than the overall average temperature, and the effective cooling time exceeds 1h, and the cooling suit has a significant cooling effect.
