Description

Technical Field

[0001] The present invention relates to the technical field of down jackets, and particularly to a heat and moisture force balance fabric layer and a down jacket. Background Art

[0002] At present, the balance between the warmth retention and the heat and moisture comfort of down jackets is a common problem. Specifically, when the human body is exercising, the body temperature will rise and a large amount of heat will be generated. At the same time, the human body will dissipate heat by sweating. However, traditional down jackets often have insufficient breathability and are difficult to help the human body quickly dissipate heat after exercise. As a result, sweat will accumulate on the skin surface of the human body, causing discomfort. And taking off the down jacket at this time will make the human body catch a cold due to the sudden drop in temperature. On the other hand, when the external temperature drops, since the human body's perception of cold becomes particularly sensitive, the down jacket is required to quickly provide sufficient heat in a short time to ensure its warmth retention effect. Correspondingly, although in the prior art, different functional areas are divided on the down jacket to improve the warmth retention performance and control the amount of cold air entering from the outside, and some down jackets are provided with warm bodies at the waist and other parts to improve the comfort of wearing the clothes, it is difficult to ensure the heat and moisture comfort of the down jacket. Therefore, how to ensure that clothing such as down jackets can be intelligently adjusted according to the temperature change of the human body, improve the warmth retention while ensuring the heat and moisture comfort of users is a problem that needs to be solved by those skilled in the art at present.

[0014] Optionally, the water outlet of the heat and moisture balance fabric layer is arranged on the bottom edge of the back piece of the back piece area.

[0015] Optionally, one end of the connecting piece part is connected to the back piece part, and the other end is connected to the front piece part. A side seam is arranged between the back piece area and the front piece area. The connecting piece part and the front piece part are both arranged at an angle to the side seam.

[0016] Advantages of the present invention:

[0017] In the present invention, the heat and moisture balance fabric layer is provided with a temperature control layer and an exhaust passage, and the exhaust passage is opened when the temperature control layer is in a contracted state, so that the sweat and hot air of the human body after exercise can be quickly discharged, avoiding discomfort caused by the accumulation of sweat, etc.; when the temperature control layer is in an expanded state, the exhaust passage is closed, so as to avoid excessive dissipation of the hot air of the human body, so that enough heat can be provided in a short time to ensure the temperature of the human body and achieve the heat preservation effect.

[0028] The technical solution of this embodiment will be further described below in conjunction with the accompanying drawings and through specific implementation manners.

[0029] As Figures 1 - 5 shown, this embodiment provides a thermo-humidity force balance fabric layer, which includes a moisture-conducting layer 10, a temperature-control layer 20, a bladder cloth 30, a moisture-exhausting and heat-preserving layer 40, and a surface cloth 50 arranged in sequence from inside to 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-exhausting and heat-preserving layer 40 and the surface cloth 50. When the temperature-control layer 20 is in the contracted state, the exhaust channel 102 is opened, and hot air 100 can enter the exhaust channel 102 through the moisture-conducting layer 10, the temperature-control layer 20, the bladder cloth 30, and the moisture-exhausting and heat-preserving layer 40 for exhausting air and draining water; when the temperature-control layer 20 is in the expanded state, the temperature-control layer 20 expands and presses the moisture-exhausting and heat-preserving layer 40 to close the exhaust channel 102, so as to avoid the loss of hot air 100.

[0030] On the other hand, the down jacket includes a front piece area 210, a shoulder piece area 220, a rear collar area 230, and a rear piece area 240. The thermo-humidity force balance fabric layer is respectively distributed on the front piece area 210, the shoulder piece area 220, and the rear piece area 240, and is connected to the rear collar area 230.

[0031] Specifically, in this embodiment, the thermo-humidity force balance fabric layer is provided with a temperature-control layer 20 and an exhaust channel 102, and the exhaust channel 102 is opened when the temperature-control layer 20 is in the contracted state, so that the sweat and hot air 100 of the human body after exercise can be quickly discharged, avoiding the accumulation of sweat and the like from causing discomfort to the user; when the temperature-control layer 20 is in the expanded state, the exhaust channel 102 is closed, so as to avoid excessive dissipation of the hot air 100 of the human body, enabling sufficient heat to be provided in a short time to ensure the body temperature of the human body, achieving a heat-preserving effect, and thus realizing intelligent adjustment according to the temperature change of the human body and ensuring the effect of heat-preserving performance. Correspondingly, the down jacket provided with the thermo-humidity force balance fabric layer can also achieve the effect of simultaneously having heat-preserving performance and thermo-humidity comfort performance, and the three-wing ring-flow distribution of the thermo-humidity force balance fabric layer on the down jacket can also increase its contact area with the human body, thereby improving the moisture-exhausting efficiency and heat-insulating effect.

[0032] The specific structure of the thermo-hygroscopic force balance fabric layer in this embodiment will be described below.

[0033] As Figure 4 and Figure 5 shown, the thermo-hygroscopic force balance fabric layer in this embodiment includes a moisture-conducting layer 10, a temperature control layer 20, a liner cloth 30, a moisture-exhausting and heat-preserving layer 40, and a surface cloth 50 that are sequentially arranged from the inside to the outside. Optionally, in this embodiment, the human body is in contact with the moisture-conducting layer 10, and the surface cloth 50 is located on the outside and exposed to the external environment. Specifically, the thermo-hygroscopic force balance fabric layer in this embodiment is applicable to clothing such as down jackets, and can efficiently conduct ventilation, exhaust moisture, and automatically control temperature, so as to ensure the heat preservation performance of the down jacket and improve its thermo-hygroscopic comfort when the human body is in different cold and hot environments and different physiological states. Optionally, the moisture-conducting layer 10 in this embodiment is set as a sandwich mesh structure, so as to promote the circulation of air and the like, that is, the hot air 100 and sweat 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] Combined with Figure 4 and Figure 5 shown, the temperature control layer 20 in this embodiment has at least a contracted state and an expanded state. When the temperature control layer 20 is in the contracted state, the hot air 100 inside can be quickly exported to the outside to avoid the human body being in close contact with the inside of the clothing 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, improving the heat preservation effect of the clothing. Specifically, the temperature control layer 20 in this embodiment is made of a cold-expandable material, so that the temperature control layer 20 can autonomously sense the temperature rise and transform into a normal temperature mode in the contracted state, and transform into the expanded state to increase the air layer when sensing the temperature drop, providing additional heat preservation for the human body.

[0035] Specifically, a number of expansion cavities 21 are arranged in the temperature control layer 20 in this embodiment, and the internal material is made of aerogel, and the surface layer is set as a knitted mesh structure. Specifically, when the temperature rises, the expansion cavities 21 are in the contracted state, so as to ensure the smooth circulation of the hot air 100. When the temperature drops, the expansion cavities 21 are in the expanded state to provide a heat preservation effect. Exemplarily, the temperature adjustment range of the temperature control layer 20 is 5°C - 15°C, so as to ensure the effects of air permeability, high-efficiency moisture exhaust, and automatic temperature control of the thermo-hygroscopic force balance fabric layer.

[0036] Furthermore, in this embodiment, a liner cloth 30 is provided between the temperature control layer 20 and the moisture exhaust and heat preservation layer 40, which can effectively prevent the moisture exhaust and heat preservation layer 40 from slipping due to friction, thereby affecting the moisture exhaust, air exhaust and heat preservation effects. Exemplarily, the raw material of the moisture exhaust and heat preservation layer 40 in this embodiment is cotton. Specifically, it is made of needle-punched cotton, so that the hot air 100 and liquefied water vapor generated under the human body's motion state can be quickly discharged, and its interior can be insulated in the cold state to improve the heat preservation effect. In other embodiments, other materials can also be used according to needs, which is not limited here.

[0037] Combined Figures 3 - 5 As shown, in this embodiment, an exhaust channel 102 is provided between the moisture exhaust and heat preservation layer 40 and the face cloth 50. When the temperature control layer 20 is in a contracted state, the exhaust channel 102 is opened at this time, and the internal hot air 100 can enter the exhaust channel 102 through the moisture-conducting layer 10, the temperature control layer 20, the liner cloth 30 and the moisture exhaust and heat preservation layer 40 for exhaust. At the same time, its liquefied water vapor and human sweat can also enter the exhaust channel 102 through this conduction path for drainage, so that there will be no excessive hot air and sweat inside between the human body and the internal part of the heat and moisture balance fabric layer, causing problems such as airtightness and dampness. Further, when the temperature control layer 20 is in an expanded state, the temperature control layer 20 expands and presses the liner cloth 30 and the moisture exhaust and heat preservation layer 40, so as to achieve the effect of closing the exhaust channel 102, so that the internal hot air 100 will not escape to the outside in large quantities, and thus the heat preservation effect of the heat and moisture balance fabric layer can be ensured, and heat loss can be avoided. Further, 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. In this way, the hot air 100 can be discharged from the air outlet 101, and the liquefied water droplets and sweat can be discharged from the water outlet 103, so as to quickly regulate the internal temperature, and the liquid can be uniformly collected and discharged, avoiding accumulation inside the heat and moisture balance fabric layer and affecting subsequent moisture exhaust and heat preservation operations.

[0038] The following describes the specific structure of the down jacket in this embodiment.

[0039] As Figures 1 - 5 shown, the down jacket in this embodiment includes a front piece 210, a shoulder piece 220, a rear collar area 230 and a rear piece 240, and the above-mentioned heat and moisture balance fabric layer is respectively distributed on the front piece 210, the shoulder piece 220 and the rear piece 240, and is connected to the rear collar area 230, so that the heat and moisture balance fabric layer can wrap most parts of the human body, and thus achieve efficient moisture absorption and sweat discharge and ensure efficient heat preservation effect under the condition of its large coverage area.

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

[0041] Further, in this embodiment, the connecting piece portion 120 is also arranged on the rear piece area 240, the front piece portion 130 is arranged on the front piece area 210, and the shoulder piece portion 140 is arranged on the shoulder piece area 220, so as to be able to cover the human body's back, waist, abdomen, and shoulders, quickly discharge moisture and sweat during its movement and other states, and ensure the warmth effect on the human body in a cold environment. Specifically, one end of the connecting piece portion 120 is connected to the rear piece portion 110, and the other end is connected to the front piece portion 130. Both the connecting piece portion 120 and the front piece portion 130 are arranged at an angle to the side seam, so as to cover a large area in front of and behind the human waist. Exemplarily, both the connecting piece portion 120 and the front piece portion 130 are arranged in a long strip structure, and the two are symmetrically arranged with respect to the side seam, so as to ensure moisture discharge, sweat discharge, and heat preservation in front of and behind the human abdomen.

[0042] Exemplarily, in this embodiment, the back piece portion 110 and the connecting piece portion 120 are connected, and the shoulder piece portion 140 is disposed in the shoulder region 220, so that the thermo-humidity force balance fabric layer forms a three-wing circulation distribution on the down jacket, and then the thermo-humidity force of the entire down jacket can be automatically balanced according to the ambient temperature. Specifically, the thermo-humidity force balance fabric layer extends vertically downward from the back collar region 230 to the northern region in the back region 240 of the down jacket, and further expands to the side seams on both sides, showing a trend of gradually narrowing from a wider size at the upper part to a narrower size at the lower part, so as to improve the collection path of moisture absorption and sweat discharge, improve the effects of breathability, moisture discharge and automatic temperature control. Furthermore, when the human body is in different hot and cold environments and its physiological states, while ensuring the warmth retention performance of the down jacket, the thermo-humidity comfort of the down jacket is improved. Further, in the front region 210, the thermo-humidity force balance fabric layer extends obliquely upward from the side seam and covers the center line of the front region 210 and the shoulder region 220, and the positions where the thermo-humidity force balance fabric layer is not provided are filled with down. Thus, when the temperature rises, the heat and moisture emitted by the human body can be quickly discharged out of the body through the air outlet 101 and the water outlet 103 of the thermo-humidity force balance fabric layer, and when the temperature drops, the inflation of the inflation cavity 21 is used to thicken these parts, so that the user can quickly feel warm and comfortable, improving the warmth retention effect of the down jacket and realizing the intelligent balance of thermo-humidity comfort and warmth retention. Specifically, in this embodiment, the settings of the air outlet 101 and the water outlet 103 can be changed according to needs in terms of position, shape, etc., and there is no limitation here.

[0043] Working principle: When the temperature rises, the temperature control layer 20 in the thermo-humidity force balance fabric layer is in a normal state, that is, the inflation cavity 21 is in a contracted state. At this time, the exhaust passage 102 is opened, and the water vapor generated by the human body's heat dissipation can enter the exhaust passage 102 through the air-permeable holes of the moisture-conducting layer 10, the temperature control layer 20, the bile cloth 30 and the moisture-discharging and warmth-retention layer 40, and the hot air 100 is discharged upward through the air outlet 101, and the liquid such as sweat is discharged downward through the water outlet 103; when the temperature drops, the temperature control layer 20 makes the inflation cavity 21 in an inflated state under the action of its cold-expandable fabric, forming multiple air layers. On the one hand, the air-permeable holes are closed, and the moisture-discharging and warmth-retention layer 40 is squeezed until the exhaust passage 102 is closed. Thus, under the inflation effect of the temperature control layer 20, a thickness difference is generated between the thermo-humidity force balance fabric layer and the human body, so that the position of the down jacket provided with the thermo-humidity force balance fabric layer provides an efficient warmth retention effect, enabling the human body to quickly warm up and reach the 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-discharging and warmth-retention layer 40, the thermo-humidity comfort balance system of the thermo-humidity force balance fabric layer can be ensured, enabling the human body to quickly adapt to temperature changes under the alternation of hot and cold environments and achieving the effect of thermo-humidity comfort balance.

[0044] Obviously, the above embodiments of the present invention are merely examples given to clearly illustrate the present invention, rather than limitations on the implementation manners of the present invention. For those of ordinary skill 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 enumerate all implementation manners here.
