[0001] This utility model relates to the field of household products technology, and in particular to an antibacterial pillowcase structure. Background Technology
[0002] Many existing home furnishing products already utilize antibacterial technology, giving them antibacterial and deodorizing functions. Furthermore, numerous patented technologies exist for this purpose.
[0003] For example, Chinese Patent Application No. 200710121723.7 discloses a health-care antibacterial towel pillowcase, comprising two layers: a towel layer and a plain cloth layer, which are connected as one piece at the four sides of the pillowcase. The towel layer is woven from a blend of hemp fiber, arc-shaped hollow antibacterial polyester fiber, and cotton fiber. The towel layer has an outwardly raised pattern and adopts a high-low pile weaving method. The area of the raised pattern accounts for 50% to 70% of the total area of the towel layer, and the height of the pile loops in the high pile part of the pattern is 1 to 2 times higher than that of the pile loops in other parts. The towel layer contains 40% to 55% hemp fiber, 35% to 50% arc-shaped hollow antibacterial polyester fiber, and 5% to 15% cotton fiber.
[0004] Existing antibacterial pillowcases are made of fibers with antibacterial properties, but the content of antibacterial components in the fibers is not high, and the effect is not good enough because they are located within the fibers. Utility Model Content
[0005] The purpose of this invention is to provide an antibacterial pillowcase structure with better antibacterial effect.
[0006] The above-mentioned objective of this utility model is achieved through the following technical solution: an antibacterial pillowcase structure, including a front pillowcase portion and a back pillowcase portion, wherein at least one of the front pillowcase portion and the back pillowcase portion is provided with a photocatalytic surface protection structure, and the photocatalytic surface protection structure appears on at least one of the upper and lower surfaces of the front pillowcase portion and the upper and lower surfaces of the back pillowcase portion.

[0025] The present invention will be further described in detail below with reference to the accompanying drawings.
[0026] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of the present utility model.
[0027] Example 1, such as Figure 1-4 As shown, a textile structure includes a textile substrate layer 1, which can be made of woven fabric, knitted fabric, non-woven fabric, warp-knitted suede, corduroy, plush, or other fabrics. Multiple upper photocatalytic coating films 11 are discretely distributed on the upper surface of the textile substrate layer 1, and multiple lower photocatalytic coating films 12 are discretely distributed on the lower surface of the textile substrate layer 1. This is the most significant design feature of this application: the coating is fragmented and discrete, rather than being applied as a whole in existing technologies. This creates gaps between adjacent upper photocatalytic coating films 11 and adjacent lower photocatalytic coating films 12, forming areas in the textile substrate layer 1 that are easily bent and deformed, resulting in a less rigid overall structure and a softer feel.
[0028] Specifically, the area of the superimposed shadow formed by the overlapping of the projections of all the upper photocatalytic coating films 11 and all the lower photocatalytic coating films 12 in the vertical direction is less than or equal to 20% of the total area of all the upper photocatalytic coating films 11 and less than or equal to 20% of the total area of all the lower photocatalytic coating films 12. The purpose of this setting is to reduce the simultaneous presence of upper photocatalytic coating films 11 and lower photocatalytic coating films 12 on the upper and lower parts of the textile substrate layer 1. That is, the projections of the upper photocatalytic coating films 11 and lower photocatalytic coating films 12 are staggered as much as possible in the horizontal projection plane. This is also for better feel and to reduce the situation where the coating film is present on the upper and lower parts at the same time, resulting in a large thickness in the part and making many local parts feel hard and difficult to bend and deform.
[0029] The thickness of both the upper photocatalytic coating film 11 and the lower photocatalytic coating film 12 can be controlled between 200-500 nanometers. The area of the upper photocatalytic coating film 11 is less than or equal to 1 square centimeter, and the area of the lower photocatalytic coating film 12 is less than or equal to 1 square centimeter, preferably around 0.5 square centimeters. Smaller area structures will yield better results.
[0030] Furthermore, the spacing between adjacent upper photocatalytic coating films 11 is greater than or equal to 2 mm, and can be controlled at around 4 mm. Such a spacing is more suitable. Of course, the spacing between adjacent lower photocatalytic coating films 12 is also preferably greater than or equal to 2 mm.
[0031] Preferably, the upper photocatalytic coating film 11 is circular, rhomboid, or hexagonal, and the lower photocatalytic coating film 12 is circular, rhomboid, or hexagonal. Such shapes are relatively simple and practical.
[0032] Here, we introduce some of the processing techniques for the above-mentioned structure. We need a masking spraying fixture with a panel covering the textile substrate layer 1 and discrete round holes, diamond holes or hexagonal holes on the panel. These holes are for the photocatalytic coating to be sprayed onto the textile substrate layer 1 to form the upper photocatalytic coating film 11 or the lower photocatalytic coating film 12.
[0033] Preferably, the total area of the upper photocatalytic coating film 11 and the lower photocatalytic coating film 12 is 50%-90% of the area of the textile substrate layer 1, with 85% being more suitable. Here, the area is calculated only on one side; that is, even if both the upper and lower photocatalytic coating films 11 and 12 are placed on one side of the textile substrate layer 1, they will not cover the entire surface. This ratio allows for a staggered arrangement, with a portion of the photocatalytic coating film remaining on either the upper or lower side of each section. This improves practicality.
[0034] Furthermore, the textile substrate layer 1 includes two or more textile fabric pieces 10 arranged vertically, with multiple textile fabric pieces 10 stacked on top of each other, and the peripheries of all the textile fabric pieces 10 are sewn together with sewing thread. Of course, to further enhance the connection, the middle area of the textile fabric pieces 10 can also be sewn vertically to strengthen the connection effect. As mentioned above, the textile fabric pieces 10 can be woven fabric, knitted fabric, non-woven fabric, warp-knitted suede fabric, corduroy fabric, plush fabric, etc.
[0035] Furthermore, the upper photocatalytic coating film 11 is located on the upper surface of the uppermost textile fabric piece 10, and the lower photocatalytic coating film 12 is located on the lower surface of the lowermost textile fabric piece 10. The upper photocatalytic coating film 11 and the lower photocatalytic coating film 12 are staggered in the upper and lower projection planes. This design means that the upper photocatalytic coating film 11 and the lower photocatalytic coating film 12 do not overlap vertically. Moreover, an upper antistatic thread surrounds the sewing coil 110 around the upper photocatalytic coating film 11. The upper antistatic thread surrounds the sewing coil 110 and is sewn onto each textile fabric piece 10. The upper antistatic thread surrounds the sewing coil 110, which is a conventional antistatic thread bundle sewn vertically and wraps around the coil, primarily serving to stabilize the structural connection and provide antistatic effects. Similarly, a lower antistatic thread surrounds the sewing coil 120 around the lower photocatalytic coating film 12 and is sewn onto each textile fabric piece 10. Of course, the textile substrate layer 1 can also be made of just a piece of textile fabric 10 with photocatalytic coating films on the upper and lower sides, which also has good results.
[0036] Furthermore, a conductive fiber bundle 130 is sewn between the upper antistatic thread surrounding the sewing coil 110 and the lower antistatic thread surrounding the sewing coil 120. The antistatic mechanism of the antistatic thread is to dissipate most of the generated static electricity through moisture absorption, which is a leakage effect. The antistatic mechanism of the conductive fiber is mainly that when the conductive fiber is close to a charged body, it uses the electric field to induce its own corona discharge, thereby neutralizing the static electricity, which is a discharge effect. Therefore, this structure means that when the ambient humidity is low, the antistatic ability of the upper antistatic thread surrounding the sewing coil 110 and the lower antistatic thread surrounding the sewing coil 120 will decrease. At this time, the conductive fiber bundle 130 can be used to assist in the discharge.
[0037] Example 2, as Figure 5As shown, a textile protective device includes a textile structure as described in Embodiment 1. The periphery of the textile structure is connected to peripheral connectors 2 for installation and connection to the protected product. The peripheral connectors 2 can be zippers, Velcro, or plastic clips for easy disassembly. They are mainly connected around the periphery of the textile substrate layer 1, for example, by sewing the peripheral connectors 2 around the periphery of the textile substrate layer 1. These peripheral connectors 2 can be used to connect to food protective covers or daily necessities such as quilts for protection. Their antibacterial properties are very suitable for daily life. Of course, they can also be used in other situations requiring antibacterial and deodorizing properties.
[0038] Example 3, as Figure 6-8 As shown, this embodiment provides an antibacterial pillowcase structure, including a front pillowcase portion 31 and a back pillowcase portion 32. At least one of the front pillowcase portion 31 and the back pillowcase portion 32 is provided with a photocatalytic surface protection structure. The photocatalytic surface protection structure appears on at least one of the upper and lower surfaces of the front pillowcase portion 31 and the upper and lower surfaces of the back pillowcase portion 32. Pillows typically have a front pillowcase portion 31 and a back pillowcase portion 32, whose edges are sewn together using stitching, zippers, etc., to form a pillowcase for inserting a pillow core. The space between the front pillowcase portion 31 and the back pillowcase portion 32 is thus formed for inserting the pillow core. The feature of this embodiment lies in the design of the photocatalytic surface protection structure. This structure is directly applied to one or both surfaces of the front pillowcase portion 31 and / or the back pillowcase portion 32, forming a photocatalytic protective structure directly on the surface. This allows for a greater amount of photocatalytic material and a better direct surface effect.
[0039] Specifically, the photocatalytic surface protection structure includes a photocatalytic coating layer, which can be formed on the surface directly by existing photocatalytic coating methods, thereby playing a protective role on the surface.
[0040] Furthermore, the photocatalytic coating layer can be a continuous rectangular photocatalytic coating film or multiple discrete photocatalytic coating films distributed in a discrete manner. The continuous photocatalytic coating film can be formed into a large, complete film using existing continuous spraying methods. For this type of integral photocatalytic coating film structure, the area of a single continuous photocatalytic coating film 4 should ideally occupy at least 80% of the horizontal projected area of the front pillowcase portion 31, thus covering a larger area and achieving a decent antibacterial effect. However, the feel might be slightly stiff, as described in the previous embodiments. Therefore, we recommend the latter implementation method, where the photocatalytic coating layer is composed of multiple discrete photocatalytic coating films distributed in a discrete manner. This structure of multiple discrete photocatalytic coating films can adopt the implementation method of the upper photocatalytic coating film 11 and the lower photocatalytic coating film 12 in Examples 1 and 2; that is, the solutions in Examples 1 and 2 can be used in this embodiment.
[0041] Specifically, at least one of the front pillowcase portion 31 and the back pillowcase portion 32 serves as a textile substrate layer, and the photocatalytic coating layer is applied to at least one of the upper and lower surfaces of the textile substrate layer. The photocatalytic coating layer can be a continuous photocatalytic coating film structure, but multiple discrete photocatalytic coating films are more recommended and disposed on the front pillowcase portion 31 and / or the back pillowcase portion 32. Alternatively, the front pillowcase portion 31 and the back pillowcase portion 32 can be directly coated with the photocatalytic coating film as in the aforementioned embodiment's textile substrate layer. This method is relatively low-cost, but the antibacterial effect will deteriorate over long periods of use or in the event of significant accidental wear. Therefore, we recommend the following implementation method:
[0042] The first inner textile layer 33 is detachably connected to the lower surface of the front pillowcase portion 31, and the second inner textile layer 34 is detachably connected to the upper surface of the back pillowcase portion 32. Both the first inner textile layer 33 and the second inner textile layer 34 are provided with a photocatalytic coating layer. The detachable nature of the inner lining structure allows for washing and replacement, making it convenient to use and replaceable. The photocatalytic coating layer is also convenient to replace if problems occur.
[0043] Furthermore, the first inner textile layer 33 is connected to a photocatalytic coating layer at least on its lower surface and consists of multiple discrete photocatalytic coating films, and the second inner textile layer 34 is connected to a photocatalytic coating layer at least on its upper surface and consists of multiple discrete photocatalytic coating films. These discrete photocatalytic coating films can adopt an upper photocatalytic coating film 11 structure design on the upper side of the corresponding textile layer and a lower photocatalytic coating film 12 structure design on the lower side of the corresponding textile layer.
[0044] Furthermore, peripheral connectors 2 are sewn around the periphery of the first inner textile layer 33 and the periphery of the second inner textile layer 34, respectively, for detachable connection with the front pillowcase portion 31 and the back pillowcase portion 32. The peripheral connectors 2 can also adopt the structure of the aforementioned embodiment. The front pillowcase portion 31 and the back pillowcase portion 32 need to be connected to the corresponding peripheral connectors 2 on the inner textile layer to achieve detachable connection. For example, the peripheral connector 2 is a Velcro or zipper strap, then the front pillowcase portion 31 and the back pillowcase portion 32 are connected to the corresponding inner textile layer with matching Velcro or zipper straps for assembly or disassembly.
[0045] Specifically, the first inner textile layer 33 serves as a textile substrate layer, with multiple upper photocatalytic coating films discretely distributed on its upper surface and multiple lower photocatalytic coating films discretely distributed on its lower surface. The second inner textile layer 34 also serves as a textile substrate layer, with multiple upper photocatalytic coating films discretely distributed on its upper surface and multiple lower photocatalytic coating films discretely distributed on its lower surface. Both the upper and lower photocatalytic coating films are discrete photocatalytic coating films. These structures can refer to the designs in Examples 1 and 2, and antistatic and conductive structures can also be applied to them. This first inner textile layer 33 and its connected structures form the textile structure and textile protective device in Examples 1 and 2, which, when applied to pillowcases, provides excellent performance. In addition, in this embodiment, the textile substrate layer in Embodiment 1 can also be used in reverse in this embodiment. For example, the first inner textile layer 33 serves as the textile substrate layer and has multiple lower photocatalytic coating films in a discrete distribution on its upper surface and multiple upper photocatalytic coating films in a discrete distribution on its lower surface. That is, the structure of the aforementioned embodiment can also be used in reverse in this embodiment and achieve the same beneficial effect.
[0046] To further enhance comfort, a gel sheet 35 is sandwiched between the front pillowcase portion 31 and the first inner textile layer 33, making it very cool and breathable for use in summer.
[0047] Through the above structural design, the pillowcase not only has enhanced antibacterial, deodorizing, and self-cleaning capabilities, but also offers greater flexibility and comfort.
[0048] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
