Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of functional clothing, and particularly relates to a sports down jacket capable of achieving sterilization and deodorization by activating a photocatalyst through an embedded ultraviolet light source. BACKGROUND

[0002] With the continuous rise in popularity of ice and snow sports such as mountaineering, skiing, and skating, down jackets, as one of the key equipment for such ice and snow sports, have higher requirements in terms of warmth, wind resistance, waterproofness, and the like, considering their use environment. Meanwhile, since users need to engage in continuous and / or intense sports, such down jackets also need to have good air permeability. However, down, which is used to provide core warmth, has a large adsorption capacity for water vapor, bacteria, organic pollutants, and the like, which is the reason why down raw materials need to be subjected to strict cleaning and deodorization treatment to remove odors. The adsorption capacity of down makes the down jacket produce unpleasant odors due to the adsorbed bacteria, VOCs, and the like after being worn for a long time or stored in a closed state. Although washing can reduce the unpleasant odor to a certain extent, it has a high requirement for the degree of washing, that is, direct and sufficient washing of the down clusters is needed to effectively remove the bacteria, VOCs, and the like adsorbed by the down clusters.

[0003] However, due to the higher requirement level of sports down jackets, the fabric used is usually a functional fabric that is subjected to special coating and / or film coating treatment, and has a more stringent requirement for the washing method. Therefore, such down jackets usually only support dry cleaning, and even some sports down jackets using special stain-resistant fabric only support wiping. The main purpose is to prevent the fabric from being rubbed and damaged or losing functionality during washing. However, it is obvious that dry cleaning and wiping cannot effectively wash the down clusters, and therefore cannot effectively remove the bacteria, VOCs, and the like adsorbed by the down clusters.

[0004] As a means that can effectively decompose VOC and other unpleasant gases, photocatalysis technology is widely used in air purification, wastewater treatment and other fields. There are also attempts to apply photocatalysis technology to down jackets in the prior art. For example, Chinese patent CN113997653B discloses an anti-fouling and antibacterial children's down jacket, which implants titanium dioxide photocatalyst on the surface of the shell fabric and the lining fabric by mixing nano titanium dioxide with photosensitive glue and then irradiating with ultraviolet light. However, the photosensitive glue will quickly solidify after being irradiated with ultraviolet light, which results in the loss of flexibility of the shell fabric and the lining fabric or the breakage or even peeling of the coating when the shell fabric and the lining fabric are bent. Obviously, neither of these two results can meet the use requirements of the shell fabric of the down jacket. Korean patent KR20250070278A discloses another means of applying photocatalysis technology to down jackets, which realizes functionality by attaching functional particles to the surface of the down. The functional particles used are a mixture of germanium, cypress powder, volcanic ash extract, silicon dioxide nanoparticles, olivine, titanium dioxide (TiO2), nano silver powder, jade powder, red clay, adhesive resin, etc. However, the adhesion of particles to the down through an adhesive will seriously damage the fluffy structure of the down clusters and even cause the down to stick and agglomerate, resulting in the loss of its warmth retention function. In fact, since ice and snow sports are usually carried out in outdoor scenarios, especially for mountaineering, at high altitudes, the air is thin and already above the cloud layer, which will withstand much more ultraviolet radiation than at low altitudes. Therefore, to protect the user, such down jackets usually also need to have excellent ultraviolet protection function, but this will make it difficult for ultraviolet light to effectively penetrate the shell fabric, thus preventing the photocatalyst disposed on the inner side of the shell fabric from being activated, resulting in the loss of its function. SUMMARY

[0005] The technical problem solved by the present application is to provide a sports down jacket with deodorizing function to solve the problem of odor of down jackets without damaging the functionality of the shell fabric and the fluffiness of the down.

[0006] The technical solution of the present application is a sports down jacket with deodorizing function, which comprises: a shell fabric layer made of waterproof, windproof and ultraviolet-resistant material, the outer surface of which is provided with a plug-in interface, and the inner surface of which is provided with a flexible wire, the flexible wire being fixed at a predetermined position by a shielding material; a down clamping layer disposed on the inner side of the shell fabric layer, the outer surface of which is provided with a second connector; a first connector disposed on the flexible wire at intervals, one end of which is electrically connected to the flexible wire, and the other end of which is detachably connected to the second connector; an ultraviolet lamp disposed on the inner surface of the down clamping layer or the end of the second connector, and in electrical communication with the second connector; A photocatalytic layer, wherein the photocatalytic layer is loaded with nano-titanium dioxide, is correspondingly disposed inside the fleece layer and is wrapped with down, and the photocatalytic layer is activated by ultraviolet light irradiation; The inner material layer is disposed inside the photocatalytic layer.

[0007] Preferably, the photocatalytic layer is a meltblown nonwoven fabric, which is made by electrospinning a melt-mixed resin masterbatch and nano-titanium dioxide.

[0008] Preferably, the first and second connectors are male-female plug-in structures or magnetic structures, and they play a positioning role for the fleece layer when plugged in.

[0009] Preferably, the lining layer is the outer layer of an independent lining, and the second joint is located at the four corners of the lining and restricts the displacement of the lining.

[0010] Preferably, the connection between the flexible conductor and the plug interface is provided with a hot-pressing fusion, adhesive, or sewing fixing structure.

[0011] Preferably, it further includes a second fleece layer, which is disposed between the photocatalytic layer and the lining layer, and together with the fleece layer and the photocatalytic layer, forms a double-cavity down layer.

[0012] Preferably, the photocatalytic layer is filled with down on both sides to form a separated down-filled cavity and restrict the migration of the photocatalytic layer.

[0013] This invention provides a sports down jacket with deodorizing function, achieving the following technical effects: 1. This invention uses an external power source to power the ultraviolet lamp, eliminating the need for sunlight. The ultraviolet lamp directly irradiates the photocatalytic layer to decompose bacteria / VOCs, without needing to penetrate the UV-protective fabric, and can radiate to the photocatalytic layer to effectively sterilize and deodorize the down. 2. It is permissible to perform electrical sterilization and deodorization treatment on down jackets when they are not being worn, avoiding human contact with ultraviolet rays. This process will not cause ultraviolet damage to the user. 3. The ultraviolet lamp is located inside the down filling layer. The photocatalytic layer uses a melt-blown photocatalytic layer with high abrasion resistance and is wrapped in down. The butt joint structure can fix the down filling and prevent down from running out. 4. The flexible conductor and connector structure used in this sports down jacket are compatible with functional fabric layers. The flexible conductor and shielding material can avoid damaging the waterproof, windproof and UV-resistant coating of the fabric layer. Attached Figure Description

[0016] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will be described in conjunction with the accompanying drawings. Figures 1-6 The technical solutions of the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. All other embodiments obtained by those skilled in the art based on the described embodiments of the present invention are within the scope of protection of the present invention.

[0017] like Figures 1-4 As shown, this invention discloses a sports down jacket with deodorizing function, including a fabric layer 1, a lining layer 2, a fleece lining layer 6, a photocatalytic layer 7, and an ultraviolet lamp 9. The fabric layer 1 is made of waterproof, windproof, and UV-resistant material. Its outer surface is provided with a power interface 3 that penetrates the fabric layer 1, and its inner surface is provided with multiple flexible wires 4 that connect to the power interface 3. The flexible wires 4 are fixed in a preset position by a shielding material (not shown in the figure). The shielding material can be made of fabric, adhesive strips, or other materials. Its main function is to fix and shield the flexible wires 4 to restrict them to the preset position, thereby preventing the user's movements when wearing the jacket from pulling the flexible wires 4 and causing them to become misaligned.

[0018] like Figure 2 and Figure 3As shown, a plurality of first connectors 5 are spaced apart on the flexible conductor 4. One end of each first connector 5 is electrically connected to the flexible conductor 4, and the other end passes through the shielding material and is detachably connected to a second connector 8. The first connectors 5 are fixed to the inner side of the fabric layer 1 or to the shielding material by one or more conventional fixing methods such as hot pressing, adhesives, or sewing. In a specific embodiment, the first connectors 5 are fixed to the shielding material, which can maintain the stiffness of the fabric layer 1 and avoid damaging its functional structure, such as waterproof and windproof coatings.

[0019] like Figure 2 and Figure 3 As shown, the fleece layer 6 is disposed inside the fabric layer 1. The fleece layer 6 serves as a barrier between the down and the fabric layer 1. Its outer surface is provided with multiple second connectors 8 that correspond one-to-one with the first connectors 5. Thus, through the docking action of the two connectors, an electrical connection is established between the fleece layer 6 and the power interface 3. The second connectors 8 can be fixedly connected to the fleece layer 6 in the same way as the first connectors 5.

[0020] like Figure 6 As shown, the first connector 5 and the second connector 8 are male-female plug-in structures, but magnetic head structures or other structures common in the art can also be used. In a specific embodiment, the first connector 5 and the second connector 8 adopt a male-female head structure because their male-female plug-in structure can also play a positioning role for the down filling layer 6. This is very important in some down jacket manufacturing processes. For example, when the down filling layer 6 is not a whole piece of fabric similar to the outer fabric layer 1 and the lining layer 2, but multiple independent down filling outer layers, the male-female plug-in structure can achieve electrical connection while fixing the down filling in a predetermined position, preventing it from shifting due to its own weight, user movement, etc., and thus causing insulation voids (referring to areas of the down jacket without down coverage due to down accumulation or down filling misalignment).

[0021] like Figure 3 As shown, a specific arrangement of the first pair of connectors 5 and the second pair of connectors 8 is given, wherein... Figure 3 (a) Figure 3 (c) shows a planar schematic of the male-female plug-in structure and the connection method of the flexible wire 4. This example is not applicable to the two cases where the fleece layer 6 is a single piece of fabric and the outer layer of the fleece lining. Figure 3 (b) Figure 3 (d) mainly demonstrates the arrangement of the two pairs of joints when the fleece layer 6 is the outer layer of the fleece lining. Figure 3 In (d), the second pair of joints 8 are arranged at the four corners of the fleece layer 6, which serves as the outer layer of the fleece lining, compared to Figure 3 The arrangement in (c) can achieve better positioning of the wicking and effectively reduce the gap area between adjacent wickings.

[0022] like Figure 2 As shown, multiple ultraviolet lamps 9 are provided on the inner surface of the fleece layer 6 or at the end of the second connector 8 away from the first connector 5. The ultraviolet lamps 9 are electrically connected to the first connector 5, so that when the power interface 3 is connected to an external power source, the ultraviolet lamps 9 can be lit and emit ultraviolet light. The ultraviolet lamps 9 can be implemented using LED beads.

[0023] like Figure 2 and Figure 4 As shown, photocatalytic layers 7 are also spaced apart on the inner side of the fleece layer 6. When the down jacket is manufactured, the photocatalytic layers 7 are wrapped by the down. The photocatalytic layers 7 are loaded with nano-titanium dioxide. The loading method can adopt conventional forms in the art, such as using a solution composed of solvent, nano-titanium dioxide, dispersant, adhesive, etc., and loading nano-titanium dioxide onto the mesh structure by means of impregnation, spraying, brushing, etc. However, the loading fastness provided by such loading methods is too low, and due to the special application scenario of this application, that is, the photocatalytic layers 7 are wrapped by down, it needs to withstand the long-term friction of the down. Under such friction, the low loading fastness makes it difficult to maintain the photocatalytic performance for a long time.

[0024] Therefore, this invention employs a photocatalytic layer 7 in the form of meltblown nonwoven fabric. Specifically, resin masterbatch and nano-titanium dioxide particles are melt-mixed and then electrospun to form a meltblown nonwoven fabric with photocatalytic function. This load-bearing strength far exceeds that of the aforementioned impregnation, spraying, and brushing loading processes. Furthermore, when manufacturing down jackets, down can be separately filled onto both sides of the photocatalytic layer 7, forming two separate down-filled cavities on both sides of the photocatalytic layer 7. While being wrapped by the down, the photocatalytic layer 7 can also restrict its migration and prevent localized down aggregation. The nano-titanium dioxide loaded on the photocatalytic layer 7 is activated by ultraviolet light 9, thereby achieving air purification function.

[0025] like Figure 2 As shown, the inner layer 2 can be directly disposed on the inner side of the photocatalytic layer 7, thereby forming a double-cavity down layer by the combined enclosure of the fleece layer 6, the photocatalytic layer 7, and the inner layer 2. Alternatively, as... Figure 5 As shown, a second lining layer 10 is provided between the photocatalytic layer 7 and the lining layer 2, so that the lining layer 6, the photocatalytic layer 7 and the second lining layer 10 together form a double-cavity down layer; this method can be adapted to the down jacket manufacturing process using down filling, and the second lining layer 10 is actually the inner layer of the down filling.

[0026] This invention uses an external power source to power the ultraviolet lamp, eliminating the need for sunlight. The ultraviolet lamp directly irradiates the photocatalytic layer to decompose bacteria / VOCs without penetrating the UV-protective fabric, effectively sterilizing and deodorizing the down. It allows for sterilization and deodorization treatment of the down jacket when not worn, avoiding human contact with ultraviolet rays and preventing UV damage to the user. The ultraviolet lamp is located inside the down-filled layer, and the melt-blown photocatalytic layer has high abrasion resistance and is encased in down. The connector structure securely positions and fixes the down filling, preventing down leakage. The flexible conductors in this sports down jacket, combined with the connector structure, are compatible with functional fabric layers. The flexible conductors, combined with the shielding material, prevent damage to the waterproof, windproof, and UV-protective coatings of the fabric layers.

[0027] The above are preferred embodiments of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
