Description

Technical Field

[0001] The invention relates to the technical field of down jackets, and in particular to a thermal and moisture balance fabric layer and a down jacket. Background Art

[0002] At present, the balance between warmth retention and thermal and hygroscopic comfort of down jackets is a common problem. Specifically, when a human body is exercising, its body temperature rises and a large amount of heat is generated. At the same time, the human body dissipates heat through perspiration. However, traditional down jackets are often not breathable enough, which makes it difficult to help the human body dissipate heat quickly after exercise. As a result, sweat accumulates on the skin surface of the human body, causing discomfort. Taking off the down jacket at this time will cause the human body to catch a cold due to the sudden drop in temperature. On the other hand, when the outside temperature drops, the human body will become particularly sensitive to cold, so it is necessary for the down jacket to quickly provide enough heat in a short time to ensure its warmth retention effect. Correspondingly, although the prior art divides different functional areas on the down jacket to improve the warmth retention performance in order to control the amount of cold air entering from the outside, and some down jackets are provided with a warming body at the waist and other parts to improve the comfort of wearing the clothes, it is difficult to ensure the thermal and hygroscopic comfort of the down jacket. Therefore, how to ensure that down jackets and other clothing can be intelligently adjusted according to the temperature changes of the human body, and how to improve the warmth retention while ensuring the thermal and hygroscopic comfort of the user is a problem that people in this field need to solve.

[0028] The technical solution of this embodiment is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0029] like Figure 1-Figure 5 As shown, the present embodiment provides a thermal and moisture balance fabric layer, comprising a moisture conductive layer 10, a temperature control layer 20, a liner cloth 30, a moisture dissipating and thermal insulation layer 40 and a surface cloth 50 which are arranged sequentially from the inside to the outside, the temperature control layer 20 has at least a contracted state and an expanded state, and an exhaust channel 102 is arranged between the moisture dissipating and thermal insulation layer 40 and the surface cloth 50. When the temperature control layer 20 is in a contracted state, the exhaust channel 102 is opened, and the hot air 100 can enter the exhaust channel 102 through the moisture conductive layer 10, the temperature control layer 20, the liner cloth 30 and the moisture dissipating and thermal insulation layer 40 for exhaust and drainage; when the temperature control layer 20 is in an expanded state, the temperature control layer 20 expands and squeezes the moisture dissipating and thermal insulation layer 40 to close the exhaust channel 102 to prevent the loss of hot air 100.

[0030] On the other hand, the down jacket includes a front area 210 , a shoulder area 220 , a back collar area 230 and a back area 240 , and the thermal and moisture balance fabric layers are respectively distributed on the front area 210 , the shoulder area 220 and the back area 240 , and connected to the back collar area 230 .

[0031] Specifically, in this embodiment, the heat and moisture balance fabric layer is provided with a temperature control layer 20 and an exhaust channel 102, and when the temperature control layer 20 is in a contracted state, the exhaust channel 102 is opened, which can quickly discharge the sweat and heat 100 of the human body after exercise, and avoid the accumulation of sweat and the like causing discomfort to the user; when the temperature control layer 20 is in an expanded state, the exhaust channel 102 is closed, so that the excessive escape of the heat 100 of the human body can be avoided, so that sufficient heat can be provided in a short time to ensure the temperature of the human body and achieve a warming effect, so that intelligent adjustment can be achieved according to the temperature change of the human body, and the effect of warming performance can be ensured. Correspondingly, a down jacket provided with a heat and moisture balance fabric layer can also achieve the effect of both warming performance and heat and moisture comfort performance, and the three-wing circulation distribution of the heat and moisture balance fabric layer on the down jacket can also increase its contact area with the human body, thereby improving the moisture removal efficiency and the heat preservation effect.

[0032] The specific structure of the thermal and moisture balance fabric layer in this embodiment is described below.

[0033] like Figure 4 and Figure 5 As shown, the heat and moisture balance fabric layer in this embodiment includes a moisture conducting layer 10, a temperature control layer 20, a lining 30, a moisture dissipation and thermal insulation layer 40 and a face cloth 50 arranged sequentially from the inside to the outside. Optionally, in this embodiment, the human body is close to the moisture conducting layer 10, and the face cloth 50 is located on the outside and exposed to the external environment. Specifically, the heat and moisture balance fabric layer in this embodiment is suitable for down jackets and other clothing, and can be highly ventilated, dehumidified and automatically temperature controlled, so that when the human body is in different hot and cold environments and different physiological states, the warmth retention performance of the down jacket is guaranteed while improving its thermal and humid comfort. Optionally, in this embodiment, the moisture conducting layer 10 is set as a sandwich mesh structure, so that the circulation of air and the like can be promoted, that is, the hot air 100 and sweat on the inside can quickly leave the inside of the clothing under the conduction of the moisture conducting layer 10, thereby ensuring that the inside of the clothing always maintains a comfortable gas exchange.

[0034] Combination Figure 4 and Figure 5 As shown, in this embodiment, the temperature control layer 20 has at least a contracted state and an expanded state, and when the temperature control layer 20 is in the contracted state, the internal hot air 100 can be quickly discharged to the outside to avoid the human body and the inside of the clothing from being in close contact and affecting the wearing experience. When the temperature control layer 20 is in the expanded state, a large amount of hot air 100 can be prevented from escaping, thereby improving the thermal insulation effect of the clothing. Specifically, in this embodiment, the temperature control layer 20 is made of cold expansion material, so that the temperature control layer 20 can autonomously sense the temperature increase and transform into a normal temperature mode of a contracted state, and transform into an expanded state to increase the air layer when sensing the temperature drop, thereby providing an additional warming effect for the human body.

[0035] Specifically, in this embodiment, a plurality of expansion cavities 21 are provided in the temperature control layer 20, and the internal material is made of aerogel, and the surface layer is provided with a knitted mesh structure. Specifically, when the temperature rises, the expansion cavity 21 is in a contracted state, so as to ensure the smooth flow of hot air 100, and when the temperature drops, the expansion cavity 21 is in an expanded state to provide warmth. Exemplarily, the temperature adjustment range of the temperature control layer 20 is 5°C-15°C, so as to ensure the breathability, efficient moisture removal and automatic temperature control effects of the heat and moisture balance fabric layer.

[0036] Furthermore, in this embodiment, a lining cloth 30 is provided between the temperature control layer 20 and the moisture dissipation and thermal insulation layer 40, which can effectively prevent the moisture dissipation and thermal insulation layer 40 from slipping due to friction, thereby affecting the moisture dissipation, exhaust and thermal insulation effects. Exemplarily, the raw material of the moisture dissipation and thermal insulation layer 40 in this embodiment is cotton, specifically, it is made of needle cotton, so that the hot air 100 and liquefied water vapor generated by the human body in motion can be quickly discharged, and the inside can be kept warm in a cold state to improve the thermal insulation effect. In other embodiments, other materials can also be used as needed, which is not limited here.

[0037] Combination Figure 3-Figure 5 As shown, in this embodiment, an exhaust channel 102 is provided between the moisture dissipation and thermal insulation layer 40 and the surface cloth 50. When the temperature control layer 20 is in a contracted state, the exhaust channel 102 is open, and the internal hot air 100 can enter the exhaust channel 102 through the moisture conductive layer 10, the temperature control layer 20, the lining cloth 30 and the moisture dissipation and thermal insulation layer 40 for exhaust. At the same time, its liquefied water vapor and human sweat can also enter the exhaust channel 102 through the conduction path for drainage, so that there will not be too much hot air and sweat between the human body and the inside of the heat and moisture balance fabric layer, causing problems such as airtightness and humidity. Furthermore, when the temperature control layer 20 is in an expanded state, the temperature control layer 20 expands and squeezes the lining cloth 30 and the moisture dissipation and thermal insulation layer 40, thereby achieving the effect of closing the exhaust channel 102, so that the internal hot air 100 will not escape to the outside in large quantities, thereby ensuring the warmth effect of the heat and moisture balance fabric layer and avoiding heat loss. Furthermore, in this embodiment, an air outlet 101 is provided at the top of the exhaust channel 102, and a water outlet 103 is provided at the bottom, so that hot air 100 can be discharged from the air outlet 101, and liquefied water droplets and sweat can be discharged from the water outlet 103, so as to quickly regulate the internal temperature and enable the liquid to be uniformly collected and discharged to avoid accumulation inside the thermal and moisture balance fabric layer, affecting subsequent moisture removal and warmth retention operations.

[0038] The specific structure of the down jacket in this embodiment is described below.

[0039] like Figure 1-Figure 5 As shown, the down jacket in this embodiment includes a front area 210, a shoulder area 220, a back collar area 230 and a back area 240, and the above-mentioned thermal and moisture balance fabric layer is respectively distributed on the front area 210, the shoulder area 220 and the back area 240, and is connected to the back collar area 230, so that the thermal and moisture balance fabric layer can wrap around most parts of the human body, thereby achieving efficient moisture absorption and perspiration and ensuring efficient warmth retention when its coverage area is large.

[0040] like Figure 3As shown, specifically, in this embodiment, the heat and moisture balance fabric layer is provided with a rear sheet 110, a connecting sheet 120, a front sheet 130 and a shoulder sheet 140. Specifically, in this embodiment, the rear sheet 110 is set to a trapezoidal structure, and the rear sheet 110 is set in the rear sheet area 240, and the top of the rear sheet 110 is connected to the rear collar area 230, and the air outlet 101 is set at the top of the rear sheet 110, so as to ensure the smooth discharge of the hot air 100. Further, the water outlet 103 is set on the bottom edge 241 of the rear sheet of the rear sheet area 240, and at least two water outlets 103 are provided, which are respectively arranged near the side seams between the rear sheet area 240 and the front sheet area 210, so as to ensure that the liquid in the heat and moisture balance fabric layer can be uniformly collected to the water outlet 103 for discharge, thereby ensuring that the liquid such as sweat can flow out smoothly.

[0041] Furthermore, in this embodiment, the connecting sheet 120 is also arranged on the back sheet area 240, the front sheet 130 is arranged on the front sheet area 210, and the shoulder sheet 140 is arranged on the shoulder sheet area 220, so that the back, waist, abdomen and shoulders of the human body can be covered, and moisture and sweat can be quickly discharged when the human body is in motion, and the warming effect of the human body can be ensured in a cold environment. Specifically, one end of the connecting sheet 120 is connected to the back sheet 110, and the other end is connected to the front sheet 130, and the connecting sheet 120 and the front sheet 130 are both arranged at an angle with the side seam line, so as to cover a large area of ​​the front and back of the human waist. Exemplarily, the connecting sheet 120 and the front sheet 130 are both arranged in a long strip structure, and the two are symmetrically arranged relative to the side seam line, so as to ensure moisture and sweat discharge and heat preservation of the front and back of the human abdomen.

[0042] For example, in this embodiment, the back sheet 110 and the connecting sheet 120 are connected, and the shoulder sheet 140 is arranged in the shoulder area 220, so that the heat and moisture balance fabric layer forms a three-wing circulation distribution on the down jacket, thereby achieving the effect that the heat and moisture of the entire down jacket can be automatically balanced according to the ambient temperature. Specifically, the heat and moisture balance fabric layer extends vertically downward from the back collar area 230 to the northern area in the back sheet area 240 of the down jacket, and further extends to the side seams on both sides, showing a trend of gradually narrowing downward from the wider size at the top, so as to improve the collection path of moisture absorption and perspiration, improve the effects of ventilation, moisture removal and automatic temperature control, and then ensure the warmth retention performance of the down jacket while improving its heat and moisture comfort when the human body is in different cold and hot environments and its physiological state. Furthermore, at the front area 210, the heat and moisture balance fabric layer extends obliquely upward from the side seam line and covers the center line of the front area 210 and the shoulder area 220, while the remaining positions where the heat and moisture balance fabric layer is not set are filled with down. Therefore, when the temperature rises, the heat and moisture emitted by the human body can be discharged from the body as quickly as possible through the air outlet 101 and the water outlet 103 of the heat and moisture balance fabric layer, and when the temperature drops, the expansion of the expansion cavity 21 is used to thicken these parts, so that the user can quickly feel warm and comfortable, improve the warmth retention effect of the down jacket, and achieve intelligent balance of heat and moisture comfort and warmth retention. Specifically, the settings of the air outlet 101 and the water outlet 103 in this embodiment can be changed in position and shape as needed, and there is no limitation here.

[0043] Working principle: when the temperature rises, the temperature control layer 20 in the thermal and moisture balance fabric layer is in a normal state, that is, the expansion cavity 21 is in a contracted state, at this time, the exhaust channel 102 is opened, and the water vapor generated by the heat dissipation of the human body can enter the exhaust channel 102 through the air permeable holes of the moisture conductive layer 10, the temperature control layer 20, the bile cloth 30 and the moisture dissipation and thermal insulation layer 40, and discharge the hot air 100 upward through the air outlet 101, and discharge the sweat and other liquids downward through the water outlet 103; when the temperature drops, the temperature control layer 20, under the action of its cold expansion fabric, makes the expansion cavity 21 in an expanded state to form multiple air layers, on the one hand, closes the air permeable holes, and squeezes the moisture dissipation and thermal insulation layer 40 until the exhaust channel 102 is closed, so that under the expansion effect of the temperature control layer 20, a thickness difference is generated between the thermal and moisture balance fabric layer and the human body, so that the position where the thermal and moisture balance fabric layer of the down jacket is set provides an efficient warming effect, so that the human body can quickly warm up and reach a corresponding comfortable temperature. Therefore, under the action of the three-layer structure of the breathable moisture-conducting layer 10, the intelligent temperature control layer 20 and the moisture-wicking thermal insulation layer 40, the thermal and moisture-balanced fabric layer's thermal and moisture-comfortable balance system can be ensured, so that the human body can quickly adapt to temperature changes in alternating cold and hot environments, achieving a thermal and moisture-comfortable balance effect.

[0044] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the embodiments here.
