Description

Technical Field

[0001] The present invention belongs to the technical field of special down jackets, and in particular relates to an aviation-use self-temperature regulating component in a special down jacket, and a manufacturing method, a device and an application thereof. Background Art

[0002] At present, the research on down jackets generally focuses on properties such as lightness, fluffiness, windproofness and warmth, while the research on special down jackets for special purposes is relatively lacking. The demand for special down jackets generally requires that they can meet the warmth needs in general environments and can also cope with extreme challenges in special environments to protect users from being affected in a short period of time.

[0003] Among them, special down jackets used for aviation generally need to be temperature-controlled according to the ambient temperature. However, existing special down jackets are relatively lacking in temperature control and lack independent self-temperature-regulating components. It is difficult for the same down jacket to effectively perform functions such as windproof, breathable, warm, and temperature-control, and it cannot provide effective protection for users in extreme environments. Summary of the Invention

[0004] The purpose of the present invention is to provide a self-temperature regulating component for aviation use in a special down jacket and its manufacturing method, device and application in order to solve the above problems.

[0005] The present invention achieves the above-mentioned purpose through the following technical solutions: A self-temperature regulating component for aviation use in a special down jacket includes an inner layer of fabric and a temperature sensor and a controller arranged on the surface of the inner layer of fabric. The inner layer of fabric includes a fabric base layer and a composite layer. A heating element is arranged between the composite layer and the fabric base layer. A ventilation cavity is provided at the joint between the composite layer and the fabric base layer. The ventilation cavity extends longitudinally and has an opening at the bottom of the ventilation cavity for communicating with the outside world.

[0006] After the composite layer is bonded to the fabric base layer, they are connected by adhesion, and the bonding area is provided with an adhesion area and a non-adhesion area. The ventilation cavity is formed by the bulge of the non-adhesion area. The function of the ventilation cavity is to ventilate and exhaust in a higher temperature environment. When necessary, air can be pumped in through an external device. The air enters the ventilation cavity to prop up the composite layer into a strip-shaped bulge, and then enters between the down jacket and the human body through the tiny gaps in the ventilation cavity to take away moisture. When exhaust is not needed, the ventilation cavity does not bulge, so that the inner layer of fabric is bonded to the surface of the human body.

[0007] As a further optimization scheme of the present invention, the heating element is a strip-shaped electric heating wire, which is evenly distributed in the fitting gap between the composite layer and the fabric base layer. The temperature is precisely controlled by the heating element, a temperature sensor, and a controller. It has effective heating ability under extremely low temperature external environment. The composite layer includes a sandwich portion and outer fabrics arranged on both sides of the sandwich portion, one side of the outer fabric is used to adhere to the fabric base layer, and the sandwich portion is also provided with temperature-sensitive shape memory polymer particles. In an extremely cold environment, the heating element heats it to expand, blocking the composite layer and reducing the air permeability of the composite layer to improve the windproof effect.

[0008] As a further optimization scheme of the present invention, the self-temperature regulating component also includes an inner hem, which is used to be connected to the hem of the down jacket. A hollow cavity is provided inside the inner hem, and an elastic band is fixedly provided in the hollow cavity. The air supply structure includes a ventilation pipe fixedly provided on the surface of the elastic band, and the ventilation pipe is provided with a plurality of auxiliary connecting pipes for communicating with the ventilation cavity. One end of the ventilation pipe is connected to an external air supply pump. This scheme allows the inner hem to fit the human body by providing an elastic band. When ventilation is needed, the pressurized airflow enters the ventilation pipe and tends to expand outward. The elastic band is driven by the ventilation pipe to open a leakage gap, which facilitates the discharge of airflow.

[0009] As a further optimization scheme of the present invention, the elastic band is connected to the ventilation pipe through a point-shaped adhesion portion, and a pleated portion is provided on the ventilation pipe, and the pleated portion is provided between the point-shaped adhesion portions. This scheme is to further improve the ability of the elastic band to stretch out when the ventilation pipe is subjected to internal airflow pressure.

[0010] In order to manufacture any of the above-mentioned self-temperature-regulating components, the present invention further provides a method for manufacturing a self-temperature-regulating component for aviation use in a special down jacket, comprising the following steps: S1: Pure acrylic latex is used as an adhesive, and thermosensitive shape memory polymer particles are added to it. After mixing, it serves as a sandwich part to adhere the two outer fabrics to form a composite layer; S2: A heating element is arranged on the surface of the fabric base to heat-press the fabric base layer and the composite layer. A ventilation cavity is left during the bonding process, and an opening is provided at the bottom of the ventilation cavity; S3: Connect the ventilation chamber to the external air supply pump.

[0011] As a further optimization scheme of the present invention, the interlayer part is mixed by weight of 15-20 parts of pure acrylic latex and 5-10 parts of thermosensitive shape memory polymer particles, the mixing temperature is 45-60°C, and the particle size of the thermosensitive shape memory polymer particles is 50-200μm.

[0012] In order to implement the above-mentioned manufacturing method, the present invention further proposes a manufacturing device for bonding the fabric base layer and the composite layer, comprising: A hot pressing mechanism, comprising a base and a hot pressing portion, wherein the hot pressing portion is provided with a groove; A support device, which is used to form a ventilation cavity during hot pressing, includes a box body and several pairs of support plates extending from the box body. Each pair of support plates is provided with a protrusion that slides in and out of each other, and the end portions of the support plates are slidably connected to the box body along the vertical direction of the support plates. The end portions of the support plates are provided with internal threaded parts, and a threaded drive portion is provided in the box body to drive each pair of support plates to open and close.

[0013] As a further optimization solution of the present invention, the supporting device further includes a track and a feeding assembly, and the box is arranged on the feeding assembly.

[0014] As a further optimization scheme of the present invention, a pulling device is provided in the box body and the support sheet to prevent the far end of the support sheet from being adhered during hot pressing, including a guide wheel arranged on the internal threaded part, an inner groove is provided inside the support sheet, and a pulling rope is provided through the inner groove. One end of the pulling rope is connected to the raised portion at the far end of the adjacent support sheet, and the other end is connected to the connecting portion arranged in the box body after being turned by the guide wheel. The pulling device is provided to prevent the far end support sheet from being adhered by glue, which makes it difficult for each pair of support sheets to be folded.

[0015] The present invention also proposes the application of a self-temperature-regulating component for aviation use in a special down jacket. The self-temperature-regulating component is attached to the inner side of the down jacket, and the fabric base layer is fixedly connected to the inner lining of the down jacket by sewing, bonding, zippers or buttons. The connection between the fabric base layer and the down jacket can be set to a detachable type through zippers and buttons, or can be set to a fixed connection such as sewing, bonding, etc.

[0016] The beneficial effects of the present invention are: The present invention provides a ventilation cavity, which is heated and insulated by a heating element when the external airflow is extremely low; when the temperature is higher, gas is introduced into the ventilation pipe through an external air pump, so that the ventilation cavity is pressurized and bulges, and after the bulge, a gap is formed between the down jacket and the human body. The gas in the ventilation cavity enters the above gap through the pores on the surface of the composite layer, takes away the heat and is discharged from the hem, thereby improving the temperature regulation ability and being suitable for aviation down jackets.

[0018] The present application is described in further detail below in conjunction with the accompanying drawings. It is necessary to point out that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technicians in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0019] Example 1 like Figure 1-6 As shown, a self-temperature regulating component for aviation use in a special down jacket includes an inner layer fabric 1, a temperature sensor 15 arranged on the surface of the inner layer fabric 1, and a controller. The inner layer fabric 1 includes a fabric base layer 11 and a composite layer 12. A heating element 14 is provided between the composite layer 12 and the fabric base layer 11. A ventilation cavity 13 is provided at the joint between the composite layer 12 and the fabric base layer 11. The ventilation cavity 13 extends longitudinally and has an opening at the bottom of the ventilation cavity 13 for communicating with the outside world. The ventilation cavity 13 can also be connected to the ventilation cavity 13 through an external device such as a small portable air supply pump or an airbag.

[0020] After the composite layer 12 is bonded to the fabric base layer 11, they are connected by adhesion, and the bonding portion is provided with an adhesion area and a non-adhesion area. The ventilation cavity 13 is formed by the bulge of the non-adhesion area. The function of the ventilation cavity 13 is to ventilate and exhaust in a high temperature environment. When necessary, air can be pumped in through an external device. The air enters the ventilation cavity 13 to stretch the composite layer 12 into a strip-shaped bulge, and then enters between the down jacket and the human body through the tiny gaps in the ventilation cavity 13 to take away moisture. When exhaust is not needed, the ventilation cavity 13 does not bulge, so that the inner layer of fabric 1 is bonded to the surface of the human body.

[0021] The heating element 14 is a strip-shaped electric heating wire, which is evenly distributed in the fitting gap between the composite layer 12 and the fabric base layer 11. The heating element 14 also includes a switch and a button power supply, which is arranged on the outside of the fabric base layer 11. The heating element 14, the temperature sensor 15, and the controller are used to accurately control the temperature. Under extremely low temperatures in the external environment, it has effective heating capabilities. The composite layer 12 includes a sandwich portion 1202 and outer fabrics 1201 arranged on both sides of the sandwich portion 1202, one side of the outer fabric 1201 is used to adhere to the fabric base layer 11, and the sandwich portion 1202 is also provided with temperature-sensitive shape memory polymer particles 1203. In an extremely cold environment, the heating element 14 heats it to expand, blocking the composite layer and reducing the air permeability of the composite layer 12 to improve the windproof effect.

[0022] The self-temperature regulating component also includes an inner hem 2, which is used to be connected to the hem of the down jacket. A hollow cavity 21 is provided inside the inner hem 2, and an elastic band 22 is fixedly provided in the hollow cavity 21. The air supply structure includes a ventilation pipe 23 fixedly provided on the surface of the elastic band 22. The ventilation pipe 23 is provided with a number of auxiliary connecting pipes 2302 for communicating with the ventilation cavity 13. When necessary, one end of the ventilation pipe 23 is connected to an external device. This solution allows the inner hem 2 to fit the human body by providing an elastic band 22. When ventilation is needed, the pressurized airflow entering the ventilation pipe 23 tends to expand outward. The outward expansion of the ventilation pipe 23 drives the elastic band to open a gap, which facilitates the discharge of airflow from the hem.

[0023] The elastic band 22 and the ventilation tube 23 are connected by a point-shaped adhesion portion, and a pleated portion 2301 is provided on the ventilation tube 23, and the pleated portion 2301 is provided between the point-shaped adhesion portions. This solution is to further improve the ability of the ventilation tube 23 to stretch the elastic band 22 when it is subjected to internal airflow pressure.

[0024] In order to manufacture any of the above-mentioned self-temperature regulating components, the present invention further provides a method for manufacturing a self-temperature regulating component for aviation use in a special down jacket, comprising the following steps: S1: Pure acrylic latex is used as an adhesive, and thermosensitive shape memory polymer particles 1203 are added thereto. After mixing, the mixture serves as an interlayer 1202 to bond the two outer fabrics 1201 together to form a composite layer 12; S2: A heating element 14 is arranged on the surface of the fabric base 11 to heat-press the fabric base 11 and the composite layer 12, leaving a ventilation cavity 13 during the bonding process, and an opening is provided at the bottom of the ventilation cavity 13; S3: Connect the ventilation chamber 13 to an external air supply pump.

[0025] The interlayer portion 1202 is composed of 15 parts of pure acrylic latex and 8 parts of thermosensitive shape memory polymer particles 1203, by weight, and the mixing temperature is 50°C. The particle size of the thermosensitive shape memory polymer particles 1203 is 100 μm. In this embodiment, the thermosensitive shape memory polymer particles 1203 are polyurethane-based shape memory polymers. The glass transition temperature is adjusted to about 50°C by adjusting the length of the soft segment or introducing a flexible chain segment, and the amplitude of its volume expansion is increased by using a thermally expandable filler.

[0026] In order to implement the above-mentioned production method, Figure 7-10 As shown, the present invention further provides a manufacturing device for implementing the bonding of the fabric base layer 11 and the composite layer 12 in step S2, comprising: The hot pressing mechanism 3 includes a base 31 and a hot pressing portion 32 , wherein the hot pressing portion 32 is provided with a groove 33 ; The support device 4 is used to form a ventilation cavity 13 during hot pressing, and includes a box body 43 and several pairs of support plates 44 extending from the box body 43. A protrusion 45 that slides in engagement with each other is provided between each pair of support plates 44, and the end portions of the support plates 44 are slidably connected to the box body 43 along a vertical direction of the support plates 44. A limiting portion 46 is provided on the support plate 44 to limit the sliding direction of the support plate 44. An internal threaded part 47 is provided at the end portion of the support plate 44, and a threaded drive portion 48 is provided in the box body 43 to drive each pair of support plates 44 to open and close.

[0027] The supporting device 4 further includes a track 41 and a feeding assembly 42 , and a box 43 is disposed on the feeding assembly 42 .

[0028] A pulling device 5 is provided in the box body 43 and the support sheet 44 to prevent the distal end of the support sheet 44 from being adhered during hot pressing, including a guide wheel 51 provided on the internal threaded part 47, an inner groove 49 is provided inside the support sheet 44, and a pulling rope 52 is provided through the inner groove 49. One end of the pulling rope 52 is connected to the protrusion 45 at the distal end of the adjacent support sheet 44, and the other end is connected to the connecting part 53 provided in the box body 43 after being turned by the guide wheel 51. The pulling device 5 is provided to prevent the distal end of the support sheet 44 from being adhered by glue, which makes it difficult for each pair of support sheets 44 to be folded.

[0029] When the device is in operation, the adhesive on the fabric base layer 11 is placed on the base 31, and the position of the ventilation cavity 13 is not coated with adhesive. Then the feeding assembly 42 extends the support sheet 44 above the base 31. At this time, each pair of support sheets 44 are away from each other to increase the width. Corresponding to the position of the ventilation cavity 13, the support sheets 44 are used to make the composite layer 12 on the ventilation cavity 13 have a small amount of wrinkles during hot pressing, so that it can have a larger expansion amplitude when inflated, and support the gap between the human body. The groove 33 of the hot pressing mechanism 3 corresponds to the support sheet 44, and the hot pressing After completion, in order to facilitate the retraction of the support sheets 44, the two support sheets 44 are driven by the threaded drive part 48 to move closer to each other and fold together, thereby reducing the total width of each pair of support sheets 44. Furthermore, in order to prevent the distal ends of the support sheets 44 from being stuck to the edges by the adhesive and becoming difficult to fold, a pulling device 5 is provided in this embodiment. When the support sheets 44 are folded together, the traction rope 52 provides a pulling force, which causes the protrusions 45 at the distal ends of the support sheets 44 to fold together, thereby solving the problem of the edges of the support sheets 44 being stuck together. After folding, the support sheets 44 return to leave the ventilation cavity 13 through the feeding assembly 42.

[0030] The above-mentioned self-temperature regulating component can be applied to down jackets. When in use, the self-temperature regulating component is attached to the inner side of the down jacket, and the fabric base layer 11 is fixedly connected to the inner lining of the down jacket by sewing, bonding, zippers or buttons. The connection between the fabric base layer 11 and the down jacket can be set to be detachable through zippers and buttons, or it can be set to be fixed by sewing, bonding, etc.

[0031] Comparative Example 1 Different from Example 1, a manufacturing method of this embodiment includes the following steps: S1: Using pure acrylic latex as the interlayer 1202 to bond the two outer fabrics 1201 to form a composite layer 12, stirring at 50°C; S2: A heating element 14 is arranged on the surface of the fabric base 11 to bond the fabric base 11 and the composite layer 12, leaving a ventilation cavity 13 during the bonding process; S3: Connect the inner hem 2 to the inner layer fabric 1 and connect the air supply structure to the ventilation cavity 13.

[0032] Comparative Example 2 S1: Pure acrylic latex is used as an adhesive, and aerogel particles are added thereto. After mixing, the two outer fabrics 1201 are bonded together to form a sandwich portion 1202, whereby the sandwich portion 1202 is formed by mixing, by weight, 18 parts of pure acrylic latex and 7 parts of aerogel particles at a mixing temperature of 50°C. The aerogel particles have a particle size of 100 μm. S2: A heating element 14 is arranged on the surface of the fabric base 11 to bond the fabric base 11 and the composite layer 12, leaving a ventilation cavity 13 during the bonding process; S3: Connect the inner hem 2 to the inner layer fabric 1 and connect the air supply structure to the ventilation cavity 13.

[0033] Based on the national standard (GB / T5433), the air permeability of the fabric samples was tested using a YG461G fully automatic fabric air permeability meter. The air permeability was measured with and without the heating element activated. The experimental parameters were: ambient temperature 25°C, relative humidity 60%, differential pressure 100 Pa, air permeability area 20 cm², and nozzle diameter 0.8 mm. The fabric samples were tested 10 times at different locations, and the average value was used as the final air permeability data. The obtained air permeability data is as follows: ; It can be seen that in Comparative Example 1, the interlayer portion 1202 does not contain the thermosensitive shape memory polymer particles 1203, and the interlayer portion 1202 lacks pores, so its air permeability is poor. In Comparative Example 2, aerogel is used to form pores in the interlayer portion 1202, which has good air permeability. However, after the heating element is turned on, that is, when windproof and warmth-keeping are required, its air permeability cannot be reduced as required, and its ability to adapt to the temperature regulation of the environment is poor.

[0034] The above-described embodiments merely illustrate several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, and all such variations and improvements fall within the scope of protection of the present invention.
