Description

Technical Field

[0001] The invention relates to the technical field of fabrics, in particular to an antibacterial sofa cover and a preparation method thereof. Background Art

[0002] The sofa cover is put on the outside of the sofa sponge and comes into contact with the body, clothing and other items, reducing damage to the sofa sponge and reducing pollution to the sofa sponge, making it easier to clean the surface of the sofa cover.

[0003] When people come back from outside, their bodies and clothes contain a lot of bacteria and dust. When they sit on the sofa, bacteria and dust will be contaminated on the surface of the sofa cover. Compared with organic or polymer antibacterial materials, photocatalytic antibacterial materials have the advantages of long-lasting antibacterial, broad antibacterial spectrum, green environmental protection and stable performance, and are widely used in fabric production.

[0004] The use of photocatalytic antibacterial agents generally involves applying a padding / coating finishing method or a co-spinning method to textiles to carry photocatalytic antibacterial materials. However, in the padding / coating finishing method, physical contact during the use and cleaning of the textile will cause the photocatalytic antibacterial material to fall off, resulting in a reduced antibacterial effect. The co-spinning method has a complex process, and due to the limitations of the textile weaving structure, less photocatalytic antibacterial material is exposed to light, resulting in a low antibacterial effect. In addition, wear and tear caused by contact with objects cannot be avoided. Therefore, how to provide a method to increase the lifespan of photocatalytic antibacterial materials on textiles is a technical problem that needs to be urgently solved by those skilled in the art. Summary of the Invention

[0005] The purpose of the present invention is to solve the problems in the prior art and to propose an antibacterial sofa cover and a preparation method thereof.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] An antibacterial sofa cover comprises an inner layer and an outer layer, wherein the outer layer is formed with a plurality of light-transmitting areas for light to pass through, a plurality of photocatalytic antibacterial components are arranged at intervals on the sides of the inner layer and the outer layer facing each other, a photocatalytic antibacterial component is arranged between two adjacent light-transmitting areas, and a light guide component is arranged between the inner layer and the outer layer to transmit light from the light-transmitting areas to the photocatalytic antibacterial components.

[0008] The present invention is further configured as follows: the light guide component includes a reflective metal layer 1, a light-conducting resin layer and a reflective metal layer 2 in sequence, the reflective metal layer 1 is connected to the outer layer, the reflective metal layer 2 is connected to the inner layer, and the reflective metal layer 1 and the reflective metal layer 2 are respectively provided with a plurality of openings 1 and openings 2.

[0009] The present invention is further configured as follows: the light-conducting resin layer is provided with groove 1 and groove 2 corresponding to opening 1 and opening 2 respectively; a number of the photocatalytic antibacterial elements are located in groove 2 and part of groove 1; and the groove 1 without the photocatalytic antibacterial element corresponds to the light-transmitting area.

[0010] The present invention is further configured such that: the photocatalytic antibacterial element comprises at least one of nano zinc oxide powder and nano titanium oxide powder.

[0011] The present invention is further configured as follows: the outer layer is woven from transparent weft yarns and a warp yarn group, the warp yarn group includes a plurality of transparent warp yarns and a plurality of connecting warp yarns, and the transparent warp yarns and the connecting warp yarns are arranged in a ratio of 1:3.

[0012] A method for preparing an antibacterial sofa cover comprises the following steps:

[0013] S1, pouring the resin into the mold, heating it for curing, and demoulding it to obtain a light-guiding resin layer;

[0014] S2, sending the light-conducting resin layer obtained in S1 into a vacuum evaporation chamber, and performing vacuum evaporation on the surface of the light-conducting resin layer, so that a first reflective metal layer and a second reflective metal layer are formed on the surface of the light-conducting resin layer;

[0015] S3, processing the reflective metal layer 1 and the reflective metal layer 2 obtained in S2 by laser grooving, so that the reflective metal layer 1 and the light-conducting resin layer respectively form an opening 1 and a groove 1, and so that the reflective metal layer 2 and the light-conducting resin layer respectively form an opening 2 and a groove 2;

[0016] S4. Apply hot melt adhesive to the inner layer, then fill the photocatalytic antibacterial element into the second groove, and use a laminating machine to laminate the inner layer and the second reflective metal layer. Apply hot melt adhesive to the outer layer, then fill the photocatalytic antibacterial element into part of the first groove, and use a laminating machine to laminate the outer layer and the first reflective metal layer, thereby completing the production of the sofa cover fabric.

[0017] S5, cleaning the sofa cover fabric obtained in S4, drying it, cutting it and sewing it to complete the production of the sofa cover.

[0018] The present invention is further configured such that when the photocatalytic antibacterial element is filled into the groove 1 and the groove 2 in S4 , the photocatalytic antibacterial element is flush with the edges of the opening 1 and the opening 2.

[0019] In summary, the present invention has the following beneficial effects:

[0020] The light will pass through the light-transmitting warp yarn and the light-transmitting weft yarn, and enter the light-conducting resin layer through the opening one and the groove one.

[0025] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. In the description of the present invention, it should be understood that the directions or positional relationships indicated by terms such as "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside" and "outside" are based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present invention. Obviously, the embodiments described are only some embodiments of the present invention, rather than all embodiments.

[0026] like Figure 1 and Figure 2As shown, the present application provides an antibacterial sofa cover that can be put on the outside of the sofa, replacing the sofa sponge in contact with clothing, body and other objects, thereby increasing the protection of the sofa sponge. The antibacterial sofa cover includes: an inner layer 1 and an outer layer 2 and a light-guiding layer. The inner layer 1 and the outer layer 2 are respectively located on both sides of the light-guiding layer, wherein the light-guiding part includes a reflective metal layer 3, a light-guiding resin layer 4 and a reflective metal layer 2 5 in sequence. The reflective metal layer 1 3 and the reflective metal layer 2 5 are respectively attached to both sides of the light-guiding resin layer 4 through a vapor deposition machine, and the reflective metal layer 1 3 is connected to the outer layer 2 through hot melt adhesive, and the reflective metal layer 2 5 is also connected to the inner layer 1 through hot melt adhesive. The optimal material for the reflective metal layer 1 3 and the reflective metal layer 2 5 is silver. Silver has good reflectivity and antibacterial effect, so that the sofa cover has an antibacterial effect.

[0027] like Figure 2 As shown, the surfaces of the reflective metal layer 1 3 and the reflective metal layer 2 5 are laser grooved, so that the reflective metal layer 1 3 and the reflective metal layer 2 5 are respectively provided with a plurality of openings 1 6 and openings 2 7, and the light-conducting resin layer 4 is respectively provided with grooves 1 8 and grooves 2 9 corresponding to the openings 1 6 and openings 2 7, the openings 1 6 and grooves 1 8 are connected, and the openings 2 7 and grooves 2 9 are connected, wherein a plurality of photocatalytic antibacterial components 11 are arranged at intervals on the side where the inner layer 1 and the outer layer 2 face each other, and the plurality of photocatalytic antibacterial components 11 are located in the grooves 2 9 and part of the grooves 1 8, and the photocatalytic antibacterial components 11 include at least one of nano zinc oxide powder and nano titanium oxide powder, and the photocatalytic antibacterial components 11 will respectively contact the outer layer 2 and the inner layer 1 through the openings 1 6 and openings 1 6, respectively.

[0028] When external light shines on the surface of the sofa cover, part of the light will pass through the outer layer 2 and shine on the photocatalytic antibacterial component 11. The nano zinc oxide powder and nano titanium oxide powder will produce a photocatalytic antibacterial effect due to the light energy, reducing the bacteria on the sofa cover and improving the antibacterial effect of the sofa cover. This method can achieve photocatalytic antibacterial while not causing damage to the photocatalytic antibacterial component 11 when the surface of the sofa cover comes into contact with the body, clothing and external objects, thereby increasing the antibacterial life of the sofa cover.

[0029] like Figure 2 and Figure 3As shown, the outer layer 2 is woven by light-transmitting weft yarns 12 and warp yarn groups, and the warp yarn group includes a number of light-transmitting warp yarns 13 and a number of connecting warp yarns 14. The light-transmitting warp yarns 13 and the connecting warp yarns 14 are arranged in a ratio of 1:3, wherein the light-transmitting weft yarns 12 and the light-transmitting warp yarns 13 are made of transparent nylon fibers, and the connecting warp yarns 14 are made of polyester fibers. Both transparent nylon fibers and polyester fibers have good wear resistance, which can increase the wear resistance of the sofa cover surface. At the interwoven position of the light-transmitting warp yarns 13 and the light-transmitting weft yarns 12 corresponding to the outer layer 2, a light-transmitting area 10 for light to pass through will be formed. External light can pass through the outer layer 2 through the light-transmitting area 10, and the groove 8 corresponding to the light-transmitting area 10 is not provided with a photocatalytic antibacterial part 11.

[0030] When external light shines on the surface of the sofa cover, part of the light will shine into the light-conducting resin layer 4 through the light-transmitting area 10, the opening 16 and the groove 18. While the light propagates in the light-conducting resin layer 4, it will shine on the reflective metal layer 13 and the reflective metal layer 2 5, and under the mirror reflection of the reflective metal layer 13 and the reflective metal layer 2 5, the light will be transmitted a certain distance in the light-conducting resin layer 4, and the light will shine on the photocatalytic antibacterial part 11 located in the groove 1 8 and the groove 2 9, so that the photocatalytic antibacterial part 11 produces an antibacterial effect, so that both the inner layer 1 and the outer layer 2 produce a photocatalytic antibacterial effect, and at the same time, it can increase the number of photocatalytic antibacterial parts 11 that can be irradiated in the sofa cover, further improving the antibacterial effect.

[0031] A method for preparing an antibacterial sofa cover comprises the following steps:

[0032] S1, pouring the resin into the mold, heating and curing, and demoulding to obtain the light-guiding resin layer 4;

[0033] S2. The light-conducting resin layer 4 obtained in S1 is conveyed into a vacuum evaporation chamber, and vacuum evaporation is performed on the surface of the light-conducting resin layer 4, so that a reflective metal layer 1 3 and a reflective metal layer 2 5 are formed on the surface of the light-conducting resin layer 4;

[0034] S3, processing the reflective metal layer 1 3 and the reflective metal layer 2 5 obtained in S2 by laser grooving, so that the reflective metal layer 1 3 and the light-conducting resin layer 4 respectively form an opening 1 6 and a groove 1 8, so that the reflective metal layer 2 5 and the light-conducting resin layer 4 respectively form an opening 2 7 and a groove 2 9;

[0035] S4. Apply hot melt adhesive to the inner layer 1, then fill the photocatalytic antibacterial element 11 into the groove 2 9 until the photocatalytic antibacterial element 11 is flush with the edge of the opening 2 7, and use a laminating machine to laminate the inner layer 1 and the reflective metal layer 2 5. Apply hot melt adhesive to the outer layer 2, then fill the photocatalytic antibacterial element 11 into part of the groove 1 8 until the photocatalytic antibacterial element 11 is flush with the edge of the opening 1 6, and use a laminating machine to laminate the outer layer 2 and the reflective metal layer 1 3, thereby completing the production of the sofa cover fabric;

[0036] S5, cleaning the sofa cover fabric obtained in S4, drying it, cutting it and sewing it to complete the production of the sofa cover.

[0037] In summary, the antibacterial sofa cover provided in this embodiment increases the photocatalytic antibacterial component 11 exposed to light, improves the overall antibacterial effect, and reduces the probability of direct contact between objects and the photocatalytic antibacterial component 11, thereby increasing the life of the antibacterial effect.
