Description

Technical Field

[0001] The present invention relates to the technical field of clothing, in particular to a high-altitude down jacket. Background Art

[0002] Down jackets, thanks to their light weight, warmth, and excellent compressibility (they can be easily stowed in a summit bag), have become essential equipment for high-altitude climbing. However, during sustained climbing, sweat produced by human metabolism evaporates and forms moisture. This moisture is difficult to effectively dissipate in the relatively closed environment of a down jacket, and tends to condense and accumulate as water droplets inside the down or on the lining. This significantly weakens the down's loftiness and thermal insulation properties, causing a sharp drop in the jacket's warmth. In extremely cold or damp conditions at high altitudes, this problem can even cause climbers to suffer from hypothermia, with serious consequences.

[0003] To address the problem of moisture accumulation, some researchers have installed ventilation zippers in the armpit area of ​​down jackets. By fully opening the ventilation zippers, air circulation can be enhanced to quickly discharge moisture. However, in high-altitude environments with temperatures below -20°C, this method of discharging moisture has significant drawbacks:

[0004] When the ventilation zipper is fully opened, the human body's underarm area will be in direct contact with the cold air outside, causing rapid loss of body heat; test data shows that when the ventilation zipper is fully opened in a high-altitude environment below -20℃, the surface temperature of the human body's underarm will drop sharply by 8 to 12℃ within 5 minutes. This drastic local heat loss not only brings intense discomfort, but also significantly increases the climber's overall risk of hypothermia. Summary of the Invention

DETAILED DESCRIPTION

[0033] Clearly, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the protection scope of the present application.

[0034] The present application provides a high-altitude down jacket, Figure 1 The overall structure of the high-altitude down jacket is shown, and the high-altitude down jacket comprises a down jacket body, the down jacket body is composed of a body 100, a hat 200 and a sleeve 300, the body 100 has an armhole 110, the sleeve 300 is fixed on the armhole 110, and a shaping strip is arranged in the edge of the armhole 110, and the armhole 110 is kept in an arched state under the support of the shaping strip; in the arched state of the armhole 110, there is a micro-space between the surrounding area of the armhole 110 and the human body;

[0035] The armpit area of the down jacket body is spliced with a passive gradient breathable cloth sheet 400, a part of the passive gradient breathable cloth sheet 400 is spliced in the sleeve 300, and the other part of the passive gradient breathable cloth sheet 400 is spliced in the body 100.

[0036] In the passive gradient breathable cloth sheet 400, the wet guide lining layer 410 can allow moisture to pass quickly, and can also quickly absorb sweat and conduct it to the fluffy cotton layer 430, which is conducive to the removal of sweat; the fluffy cotton layer 430 has a large number of curved and interlaced pores and channels, which provide space for the transmission of moisture, and can also resist the invasion of cold air; the breathable surface cloth layer 420 has stronger air permeability than the wet guide lining layer 410, which is conducive to the better removal of moisture. The passive gradient breathable cloth sheet 400 combines the wet guide lining layer 410, the fluffy cotton layer 430 and the breathable surface cloth layer 420, which can resist the invasion of cold air while removing moisture, thereby effectively reducing the loss of body heat.

[0037] When the climber moves, the moving body will deform the down jacket body, especially the area around the shoulder of the down jacket body, which constantly deforms, so that the moisture in the micro-space is extruded, thereby efficiently pushing the moisture to flow out from the passive gradient breathable cloth sheet 400, realizing the efficient and automatic removal of moisture without active operation.

[0038] In some embodiments, the body 100 includes a body lining layer contacting the human body, a body surface layer contacting the outside world, and a body down inner chamber sandwiched between the body lining layer and the body surface layer; Figure 3 An exploded structural schematic diagram of the high-altitude down jacket in the embodiment of the present application is shown, the body surface layer forms a first arc-shaped edge 111 at the armhole 110, the body down inner chamber forms a second arc-shaped edge 112 at the armhole 110, the body lining layer forms a third arc-shaped edge 113 at the armhole 110, the second arc-shaped edge 112 is retracted inwardly of the body 100 relative to the first arc-shaped edge 111, and the third arc-shaped edge 113 is retracted inwardly of the body 100 relative to the second arc-shaped edge 112, that is, the first arc-shaped edge 111, the second arc-shaped edge 112 and the third arc-shaped edge 113 are retracted inwardly in sequence, and there is a distance difference therebetween;

[0039] The first arc-shaped edge 111, the second arc-shaped edge 112 and the third arc-shaped edge 113 are all provided with a shaping strip, so that the armhole 110 can better maintain an arched state.

[0040] The sleeve 300 includes a sleeve lining layer contacting the human body, a sleeve surface layer contacting the outside world, and a sleeve down inner chamber sandwiched between the sleeve lining layer and the sleeve surface layer, the sleeve surface layer forms a fourth arc-shaped edge at the armhole 110, the sleeve down inner chamber forms a fifth arc-shaped edge at the armhole 110, and the sleeve lining layer forms a sixth arc-shaped edge at the armhole 110, the fourth arc-shaped edge, the fifth arc-shaped edge and the sixth arc-shaped edge coincide;

[0041] The first arc-shaped edge 111 and the fourth arc-shaped edge are fixedly connected, that is, the body surface layer and the sleeve surface layer are fixedly connected, which determines the appearance contour of the down jacket body; the second arc-shaped edge 112 and the fifth arc-shaped edge are fixedly connected, that is, the body down inner chamber and the sleeve down inner chamber are fixedly connected, which ensures the continuity and sealing of the down filling layer, prevents the down from being drilled, and maintains the integrity of the warm layer; the third arc-shaped edge 113 and the sixth arc-shaped edge are fixedly connected, that is, the body lining layer and the sleeve lining layer are fixedly connected, which forms a neat seam inside the garment, improves the wearing comfort, and further fixes the internal structure.

[0042] Moreover, since there is a distance difference between the first arc-shaped edge 111, the second arc-shaped edge 112 and the third arc-shaped edge 113, and the fourth arc-shaped edge, the fifth arc-shaped edge and the sixth arc-shaped edge coincide, they are pulled by each other after corresponding fixed connection, and are supported by the shaping strips, which is conducive to maintaining the arched state of the armhole 110 and improving the swayable effect of the armhole 110, so that the micro space can better promote the moisture to be discharged from the passive gradient breathable cloth sheet 400 in the movement process of the climber.

[0043] Further, the body surface cloth layer and the sleeve surface cloth layer are waterproof fabric, which can prevent rainwater from penetrating; the body lining cloth layer and the sleeve lining cloth layer are skin-friendly fabric, which is soft and comfortable.

[0044] Figure 4 The structure schematic diagram of the pressure adhesive strip in the embodiment of the present application is shown. The passive gradient air-permeable cloth piece 400 is spliced with the sleeve 300 and the body 100, and the surface of the splicing part is provided with a pressure adhesive strip 500. The pressure adhesive strip 500 is located on the outer surface of the down jacket body, and there are a plurality of air-permeable gaps 510 between the pressure adhesive strip 500 and the outer surface of the down jacket body. The pressure adhesive strip 500 can cover and protect the splicing part, and enhance the stability of the joint; at the same time, due to the existence of the air-permeable gaps 510, the moisture cannot be blocked by the pressure adhesive strip 500, and can be smoothly discharged from the air-permeable gaps 510.

[0045] Specifically, please refer to Figure 4 The width of the air-permeable gap 510 is less than or equal to 0.5 mm, which is sufficient to guide the moisture to be discharged; the air-permeable gap 510 can be formed by a non-continuous pressure adhesive process, or the air-permeable gap 510 can also be formed by rolling and pressing with a rolling wheel with indentations, and the air-permeable channel is reserved, which can avoid the influence of the pressure adhesive strip 500 on the discharge of moisture.

[0046] In some specific embodiments, the shaping strip is one of a memory metal strip, a stainless steel wire strip and a rigid plastic strip; preferably, the shaping strip is a memory metal strip, such as a nickel-titanium shape memory alloy strip, which can accurately control the phase transition temperature in the range of 35-40℃, so that even if it is deformed, it can also restore to the original state under the action of human body temperature, thereby ensuring the structural stability of the micro space.

[0047] Specifically, the width of the shaping strip ranges from 3 to 5 mm, and the thickness of the shaping strip ranges from 0.3 to 0.6 mm, which can effectively support the armhole 110 and maintain the arched state of the armhole 110, and the hiding property is good, which will not be prominent on the surface of the down jacket body.

[0048] Optionally, the width of the shaping strip can be 3 mm, 4 mm or 5 mm, and the thickness of the shaping strip can be 0.3 mm, 0.4 mm, 0.5 mm or 0.6 mm; preferably, the width of the shaping strip is 3 mm, and the thickness of the shaping strip is 0.5 mm, which has excellent supporting effect.

[0049] In some specific embodiments, the moisture-conducting lining cloth layer 410 is formed by mixing hydrophilic modified polyester fiber and bamboo fiber, the content of the hydrophilic modified polyester fiber ranges from 65 to 75 wt%, and the content of the bamboo fiber ranges from 25 to 35 wt%. The hydrophilic modified polyester fiber is hydrophilically modified by grafting polyethylene glycol (PEG), and its surface is rich in hydrophilic groups such as hydroxyl groups; the bamboo fiber has a natural porous structure and skin-friendliness, and the combination of the two can form a high-efficiency moisture-absorbing and moisture-conducting system, and at the same time has good antibacterial performance.

[0050] Optionally, the content of the hydrophilic modified polyester fiber can be 65wt%, 70wt% or 75wt%, and the content of the bamboo fiber can be 25wt%, 30wt% or 35wt%; preferably, the content of the hydrophilic modified polyester fiber is 70wt%, and the content of the bamboo fiber is 30wt%.

[0051] It should be noted that the porosity is an important indicator for measuring the ratio of the area occupied by the holes and gaps in the fabric to the total area of the fabric. The porosity of the moisture-conducting lining layer 410 ranges from 75% to 82%, which is significantly higher than the porosity level of 50% to 55% of ordinary lining fabric; the high-porosity pore structure of the moisture-conducting lining layer 410 cooperates with the hydrophilic property of the hydrophilic modified polyester fiber to utilize the capillary effect, so that sweat can be quickly absorbed and rapidly conducted and diffused along the pore network to the fluffy cotton layer 430.

[0052] In some embodiments, the air-permeable surface cloth layer 420 is woven from island fibers made of polyamide 66 (PA66) and polyethylene terephthalate (PET) by conjugate composite spinning. The content of polyamide 66 ranges from 40wt% to 50wt%, and the content of polyethylene terephthalate ranges from 50wt% to 60wt%. After alkali reduction treatment, the island fibers made of PA66 (40wt% to 50wt%) and PET (50wt% to 60wt%) conjugate composite spinning will form PA66 ultrafine fiber bundles, which will gather and entwine with each other to form an extremely complex, tortuous and interconnected micropore network structure inside and on the surface of the air-permeable surface cloth layer 420. This micropore network structure allows air to pass through these micropore channels by convection exchange when there is a pressure difference (such as wind, human movement) between the inside and outside of the air-permeable surface cloth layer 420, thereby realizing air permeability; moreover, the small gaps between the PA66 ultrafine fiber bundles are natural capillaries, which have excellent physical moisture absorption and sweat-wicking functions and can quickly guide moisture out.

[0053] Optionally, the content of polyamide 66 can be 40wt%, 45wt% or 50wt%, and the content of polyethylene terephthalate can be 50wt%, 55wt% or 60wt%; preferably, the content of polyamide 66 is 45wt%, and the content of polyethylene terephthalate is 55wt%.

[0054] It should be noted that "g / m 2 ·24h" is a unit for measuring mass permeability and is commonly used to describe the air permeability of various materials. The water vapor transmission rate of the air-permeable surface cloth layer 420 ranges from 8000g / m 2 ·24h, which indicates that the air-permeable surface cloth layer 420 has extremely strong moisture transmission capacity to ensure that moisture can pass through quickly.

[0055] Optionally, the water vapor transmission rate of the air-permeable surface fabric layer 420 can be 8000g / m 2 · 24h, 9000g / m 2 · 24h or 10000g / m 2 · 24h; preferably, the water vapor transmission rate of the air-permeable surface fabric layer 420 is 9000g / m 2 · 24h.

[0056] In some embodiments, the fluffy cotton layer 430 is a three-dimensional polyester fiber consisting of 100% polyester fiber, and the three-dimensional polyester fiber has a grammage ranging from 80 to 100g / m 2 , and a loft ranging from 250 to 300 puffs, and has a large number of curved and interlaced pores and channels, which not only transport moisture, but also resist cold air.

[0057] Optionally, the three-dimensional polyester fiber can have a grammage of 80g / m 2 , 85g / m 2 , 90g / m 2 , 95g / m 2 or 100g / m 2 , and the three-dimensional polyester fiber can have a loft of 250 puffs, 270 puffs, 290 puffs or 300 puffs; preferably, the three-dimensional polyester fiber has a grammage of 95g / m 2 and a loft of 300 puffs.

[0058] In some embodiments, referring to Figure 1 , the part of the passive gradient air-permeable fabric sheet 400 spliced in the sleeve 300 extends to the middle region of the human arm, and the part of the passive gradient air-permeable fabric sheet 400 spliced in the body 100 extends to the side region of the human abdomen. The passive gradient air-permeable fabric sheet 400 not only covers the main sweat gland area of the armpit, but also extends to the side of the abdomen, so as to accelerate the air circulation on the side of the torso and remove accumulated moisture.

[0059] In some embodiments, the moisture-conducting lining fabric layer 410 and the fluffy cotton layer 430 are bonded based on a plurality of first point-shaped hot melt adhesives, the plurality of first point-shaped hot melt adhesives are distributed in a first interval array to form a first honeycomb-shaped air-permeable bonding layer, and the first interval ranges from 0.5 to 0.8cm; the first honeycomb-shaped air-permeable bonding layer not only ensures the interlayer stability between the moisture-conducting lining fabric layer 410 and the fluffy cotton layer 430, but also makes the air-permeable area between the moisture-conducting lining fabric layer 410 and the fluffy cotton layer 430 retain more than 85%.

[0060] The breathable surface cloth layer 420 and the fluffy cotton layer 430 are bonded based on a plurality of second point-shaped hot melt adhesives, the plurality of second point-shaped hot melt adhesives are distributed in a second interval array to form a second honeycomb-shaped breathable adhesive layer, the second interval ranges from 0.5 to 0.8 cm; the second honeycomb-shaped breathable adhesive layer not only ensures the interlayer stability between the breathable surface cloth layer 420 and the fluffy cotton layer 430, but also makes the breathable area between the breathable surface cloth layer 420 and the fluffy cotton layer 430 retain more than 85%.

[0061] The breathable principle of the high-altitude down jacket of the present application is:

[0062] In the passive gradient breathable cloth piece 400, the moisture-conducting lining layer 410 can allow moisture to pass quickly, and can also quickly absorb sweat and diffuse and conduct to the fluffy cotton layer 430, which is beneficial to the removal of sweat; the fluffy cotton layer 430 has a large number of curved and interlaced pores and channels, which provide space for the transmission of moisture, and can also resist the invasion of cold air; the breathable surface cloth layer 420 has stronger breathability than the moisture-conducting lining layer 410, which is beneficial to the better removal of moisture.

[0063] The passive gradient breathable cloth piece 400 can resist the invasion of cold air while removing moisture through the combination of the moisture-conducting lining layer 410, the fluffy cotton layer 430 and the breathable surface cloth layer 420, thereby effectively reducing the loss of body heat.

[0064] When the climber moves, the moving body will deform the down jacket body, especially the area around the shoulder of the down jacket body, which constantly deforms, so that the moisture in the micro space is squeezed, thereby efficiently pushing the moisture to flow out from the passive gradient breathable cloth piece 400, realizing efficient and automatic removal of moisture without active operation.

[0065] Compared with the existing way of removing moisture through fully open breathable zippers, the high-altitude down jacket of the present application has more obvious advantages in removing moisture through micro spaces and passive gradient breathable cloth pieces, as shown in Table 1 and Table 2:

[0066] Table 1

[0067]

[0068] Table 2

[0069]

[0070] The high-altitude down jacket of the present application completely gets rid of the dependence on "breathable zippers", removes moisture automatically through the cooperation of micro spaces and passive gradient breathable cloth pieces, utilizes the synergistic effect of structure and material, realizes passive ventilation, and this process is continuous and stable, which will not cause the body temperature of the climber to fluctuate sharply, and avoids the risk of hypothermia.

[0071] Moreover, the moisture discharged by the micro-space matched passive gradient air-permeable cloth sheet is gaseous, which blocks the phase change process of "moisture→liquid water→ice crystal" from the source. After 24 hours of testing, no ice crystal is deposited on the surface of the passive gradient air-permeable cloth sheet, which can still work stably and continuously, and will not have the "freezing failure" problem at low temperature like the air-permeable zipper, and is suitable for harsh scenes such as high-altitude climbing and polar exploration.

[0072] The high-altitude down jacket provided by the embodiment of the present application is described in detail above, and the principle and implementation mode of the present application are described by using specific examples in this paper. The above embodiment is only used to help understand the method and core idea of the present application. Meanwhile, for the general technical personnel in the field, the specific implementation mode and application range will be changed according to the idea of the present application. In summary, the content of the specification should not be understood as a limitation of the present application.
