Description

Technical Field

[0001] The invention belongs to the technical field of down jackets, and in particular relates to an outdoor down jacket with antibacterial and anti-ultraviolet properties. Background Art

[0002] Down jackets are a type of cold-resistant clothing that is popular among people. This type of clothing is generally made of brightly colored fabrics and linings that can prevent down from leaking out, as well as down filled between the fabrics and the linings.

[0003] When worn in the cold winter, it is light and beautiful. With the improvement of living standards and quality of life, people have higher and higher requirements for clothing. They not only pay attention to beauty and comfort, but also put forward certain requirements for outdoor adaptability, such as anti-ultraviolet and warmth retention.

[0004] At present, down jackets only reduce the harm of ultraviolet rays to the human body by coating the fabric with an anti-ultraviolet coating. However, with the strong exposure to sunlight, the anti-ultraviolet coating will be affected by external interference and age, causing the coating to fall off from the fabric, affecting the service life of the down jacket. Moreover, when wearing a down jacket outdoors, it is difficult for the sunlight to fully shine on the down jacket. When the sunlight only shines on the back of the down jacket, there will be a temperature deviation between the back and the chest of the down jacket, causing the back temperature to be too high, causing discomfort to the wearer, and it is difficult to ensure the overall heating of the down jacket. After the reflection of light, the thermal insulation and heat locking effect of the down jacket will deteriorate. Summary of the invention

[0005] The purpose of the present invention is to provide an antibacterial and anti-ultraviolet outdoor down jacket in order to solve the above problems.

[0006] The present invention achieves the above-mentioned purpose through the following technical solutions:

[0007] An antibacterial and anti-ultraviolet outdoor down jacket, comprising an inner layer, an outer layer and down arranged in a sandwich between the outer layer and the inner layer, wherein the inner layer and the outer layer are sewn together to form an inner liner, the down is filled in the inner liner, and the outer layer comprises inner and outer breathable base fabrics, an anti-ultraviolet layer arranged on the inner surface of the inner and outer breathable base fabrics, and a modified antibacterial layer arranged in the sandwich space between the inner and outer breathable base fabrics;

[0008] The anti-ultraviolet layer comprises a mesh thermal conductive fiber, the mesh of the thermal conductive fiber is coated with an anti-ultraviolet coating, a focusing sheet for focusing sunlight is provided at the intersection of the mesh of the thermal conductive fiber, a thermal conductive edge seal is provided at the outer edge of the focusing sheet, and the thermal conductive edge seal is connected to the mesh thermal conductive fiber;

[0009] The condenser sheet comprises a first reflective sheet in a regular hexagonal shape, a second reflective sheet is arranged on the outer edge of the first reflective sheet, the first reflective sheet and the second reflective sheet form an angle, and an insulating strip is arranged at the connection between the first reflective sheet and the second reflective sheet.

[0010] The first reflective sheet comprises a mirror sheet in the shape of a regular hexagon and a light-transmitting sheet arranged on the side of the mirror sheet, wherein the center position of the light-transmitting sheet is a convex structure.

[0011] As a further optimization scheme of the present invention, the modified antibacterial layer includes porous coconut shell activated carbon particles, the internal pores of the porous coconut shell activated carbon particles are provided with adsorption particles, and the outer surface of the porous coconut shell activated carbon particles is wrapped with chitin fibers containing thermal expansion particles.

[0012] As a further optimization scheme of the present invention, in terms of mass percentage, the adsorption particles include 35%-45% tourmaline particles, 30%-40% far-infrared ceramic particles and 15%-35% carbonized wood particles.

[0013] As a further optimization scheme of the present invention, according to the mass percentage: the modified antibacterial layer includes 55%-60% porous coconut shell activated carbon particles, 25%-30% adsorption particles, and 10%-20% chitin fibers containing thermal expansion particles.

[0014] As a further optimization scheme of the present invention, the mesh thermal conductive fiber is blended from corn fiber, platycodon fiber and plant fiber.

[0015] As a further optimization scheme of the present invention, the anti-ultraviolet coating is prepared by mixing nano titanium dioxide, talcum powder, polyethylene glycol, benzotriazole and acetone.

[0019] As a further optimization solution of the present invention, the angle range is 115°-130°.

[0020] The beneficial effects of the present invention are:

[0021] (1) The present invention can effectively filter out the ultraviolet rays of sunlight by coating the inner surface of the inner and outer breathable base fabrics with an anti-ultraviolet coating. When the sunlight that has filtered out the ultraviolet rays is irradiated on the focusing sheet, the light is condensed together, and part of the focused light will be scattered, and the other part of the light will be heated on the focusing sheet. When the focusing sheet is heated, the temperature is evenly distributed to the mesh heat-conducting fiber through the heat-conducting edge sealing, so that the temperature is evenly distributed on the whole down jacket, ensuring that the wearer is evenly warmed, thereby improving the overall temperature of the down jacket, and having good cold-repelling and warmth-retaining properties and high comfort;

After the temperature is raised, the thermal conductive edge seal and the insulating strip are in a slightly molten state. On the one hand, the elasticity of the entire fabric is improved, direct sunlight is avoided, and anti-aging is strong. On the other hand, the bonding strength between the anti-ultraviolet layer and the modified antibacterial layer and the inner and outer breathable base fabrics is enhanced, the bonding stability between the surface layers is ensured, and the separation between the coating and the fabric is avoided;

[0023] (3) The present invention provides heat-expanding particles in the chitosan fiber. When the anti-ultraviolet layer is heated, the temperature is transferred to the inside of the modified antibacterial layer. Under the action of the heat-expanding particles, the chitosan fiber expands. On the one hand, the heat preservation and heat-locking effect of the expanded chitosan fiber is greatly improved. On the other hand, after the chitosan fiber expands, the pores of the chitosan fiber increase, which is convenient for releasing the adsorption particles in the porous coconut shell activated carbon particles, so as to improve the adsorption effect of the adsorption particles and greatly improve the antibacterial effect.

[0030] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here 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. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0031] Example 1

[0032] like Figure 1-2 As shown, an antibacterial and anti-ultraviolet outdoor down jacket comprises an inner layer 1, an outer layer 2 and down 3 arranged in the interlayer between the outer layer 2 and the inner layer 1, the inner layer 1 and the outer layer 2 are sewn to form an inner liner, the down 3 is filled in the inner liner, the outer layer 2 comprises inner and outer breathable base fabrics 21, an anti-ultraviolet layer 22 arranged on the inner surface of the inner and outer breathable base fabrics 21 and a modified antibacterial layer 23 arranged in the interlayer space between the inner and outer breathable base fabrics 21;

[0033] like Figure 3 As shown, the anti-ultraviolet layer 22 includes a mesh thermal conductive fiber 221, the mesh of the thermal conductive fiber 221 is coated with an anti-ultraviolet coating 222, and the mesh intersection of the thermal conductive fiber 221 is provided with a concentrating sheet 223 for focusing sunlight, and the outer edge of the concentrating sheet 223 is provided with a thermal conductive edge seal 224, and the thermal conductive edge seal 224 is connected to the thermal conductive fiber 221;

[0034] The mesh heat-conducting fiber 221 is made of a blend of corn fiber, platycodon fiber and plant fiber.

[0035] The anti-ultraviolet coating 222 is made of a mixture of nano titanium dioxide, talcum powder, polyethylene glycol, benzotriazole and acetone;

[0036] The material of the thermal conductive edge seal 224 is epoxy resin glue;

[0037] When sunlight shines on the outer layer 2 of the down jacket, the anti-ultraviolet coating 222 is provided on the inner surface of the inner and outer breathable base fabrics 21, so that the ultraviolet rays of the sunlight can be effectively filtered out. When the sunlight that has filtered out the ultraviolet rays shines on the focusing sheet 223, the light is condensed together, and part of the focused light will be scattered, and the other part of the light will be heated up on the focusing sheet 223. When the focusing sheet 223 is heated up, the temperature is evenly distributed to the mesh heat-conducting fiber 221 through the heat-conducting edge sealing 224, so as to improve the overall temperature of the down jacket, and the cold-repelling and warm-keeping performance is good;

[0038] In addition, after heating, the thermal conductive sealing edge 224 and the insulating strip 2233 are in a slightly melted state, which, on the one hand, improves the elasticity of the overall fabric, avoids direct sunlight, and has strong anti-aging properties; on the other hand, it enhances the bonding strength between the anti-ultraviolet layer 22 and the modified antibacterial layer 23 and the inner and outer breathable base fabrics 21, ensuring the stability of the bonding between the various surface layers.

[0039] like Figure 4-5 As shown, the condenser sheet 223 includes a first reflective sheet 2231 in a regular hexagonal shape, a second reflective sheet 2232 is disposed on the outer edge of the first reflective sheet 2231, the first reflective sheet 2231 and the second reflective sheet 2232 form an angle, and an insulating strip 2233 is disposed at the connection between the first reflective sheet 2231 and the second reflective sheet 2232.

[0040] The first reflective sheet 2231 includes a regular hexagonal mirror sheet and a light-transmitting sheet arranged on the side of the mirror sheet, wherein the center of the light-transmitting sheet is a convex structure;

[0041] Both sides of the second reflective sheet 2232 are transparent and arched;

[0042] The second reflective sheet 2232 is connected to the first reflective sheet 2231 and the thermal conductive edge seal 224 respectively through an insulating strip 2233, and the insulating strip 2233 is made of epoxy resin glue;

[0043] The angle range is 115°;

[0044] The sunlight passes through the internal pores of the inner and outer breathable base fabrics 21 and shines on the first reflective sheet 2231. The light first passes through the light-transmitting sheet on the first reflective sheet 2231, and the generated temperature is transmitted to the thermal conductive edge sealing 224 through the insulating strip 2233. Another part of the light is reflected, and the reflected light passes through the second reflective sheet 2232. After being refracted by the second reflective sheet 2232, the generated temperature is transmitted to the thermal conductive edge sealing 224, and the collected temperature on the thermal conductive edge sealing 224 is transmitted to the mesh thermal conductive fiber 221, thereby achieving a uniform heat conduction effect.

[0045] The modified antibacterial layer 23 comprises porous coconut shell activated carbon particles, wherein adsorption particles are arranged in the internal pores of the porous coconut shell activated carbon particles, and the outer surfaces of the porous coconut shell activated carbon particles are coated with chitosan fibers containing thermal expansion particles.

[0046] The adsorption particles include tourmaline particles, far-infrared ceramic particles and carbonized wood particles.

[0047] According to the mass percentage, the modified antibacterial layer 23 includes 55% porous coconut shell activated carbon particles, 25% adsorption particles, and 20% chitin fibers containing thermal expansion particles.

[0048] The adsorption particles include 35% tourmaline particles, 30% far-infrared ceramic particles and 35% carbonized wood particles;

[0049] Regarding the preparation of the modified antibacterial layer 23, the steps include:

[0050] Firstly, tourmaline, far-infrared ceramics and carbonized wood are taken as adsorption raw materials, and tourmaline particles, far-infrared ceramic particles and carbonized wood particles are obtained by ultra-fine grinding technology, and a certain proportion of tourmaline particles, far-infrared ceramic particles and carbonized wood particles are quantitatively added and uniformly mixed to obtain adsorption particles;

[0051] Then, the adsorbent particles and porous coconut shell activated carbon particles are taken as mixed raw materials, and a water suspension is added. After heating and stirring at 120°C for 30 minutes, chitin fibers are added, and the method of "stirring for 10 minutes and then standing for 5 minutes" is adopted. Intermittent stirring is performed for multiple times, and heat expansion particles and polyvinylidene chloride are added. After heating and stirring at 80°C for 15 minutes, the mixture is cooled at room temperature to obtain a modified antibacterial layer 23.

[0052] The adsorption particles are made of tourmaline particles, far-infrared ceramic particles and carbonized wood particles. The carbonized wood particles can adsorb odors and bacteria. Tourmaline particles and far-infrared ceramic particles can transfer far-infrared heat energy to the deeper part of the human skin during outdoor sports. The generated warmth radiates from the inside to the outside, causing the capillaries to dilate, promoting blood circulation, and strengthening the metabolism between various tissues. It is convenient for people to use and plays an antibacterial and health-care role. The chitin fiber is used to block the pores of the porous coconut shell activated carbon particles, which not only improves the overall adsorption of the porous coconut shell activated carbon particles, but also effectively avoids the loss of adsorption particles inside the porous coconut shell activated carbon particles, greatly extending the service life of the fabric.

[0053] In addition, when the temperature of the anti-ultraviolet layer 22 rises, the temperature is transferred to the inside of the modified antibacterial layer 23. Under the action of the thermal expansion particles, the chitin fiber, an effective ingredient of the modified antibacterial layer 23, will expand. On the one hand, the heat preservation and heat locking effect of the expanded chitin fiber will be greatly improved. On the other hand, after the chitin fiber expands, the pores of the chitin fiber will increase, which is convenient for releasing the adsorption particles in the porous coconut shell activated carbon particles, so as to improve the adsorption effect of the adsorption particles, and greatly improve the antibacterial effect.

[0054] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
