Abstract
Description
Technical Field
[0001] The utility model belongs to the field of bedding, in particular to a sandwich hemp pad core and a mattress. Background Art
[0002] Among the existing mattress materials, natural antibacterial fibers such as flax, ramie, jute, and coconut palm are used. However, Escherichia coli is an aerobic or facultative anaerobic bacterium that can grow in both an aerobic environment and an anaerobic environment. Conventional mattresses made of natural antibacterial fibers have an unsatisfactory bactericidal effect on facultative anaerobic bacteria such as Escherichia coli. For this reason, most antibacterial products sold on the market are added with chemical antibacterial agents, but the mattresses are not purely natural and are not environmentally friendly. Therefore, it is necessary to replace the core material of the mattress with a more environmentally friendly and better bactericidal effect. The hemp fiber currently on the market has a more ideal natural bactericidal and antibacterial function. This is because hemp fiber contains trace amounts of hemp phenols and more than ten trace elements that are beneficial to human health. These phenols have a significant antibacterial effect on a variety of bacteria. However, using hemp alone cannot keep its shape intact and is prone to loosening. Therefore, existing hemp fiber cannot be used as a core mattress alone. Utility Model Content
[0003] In view of the problem that existing mattress cores cannot take into account both environmental protection and structural integrity, the utility model provides a sandwich hemp mattress core and mattress, which realizes natural bactericidal and antibacterial functions through the hemp layer, ensuring environmental protection while ensuring structural integrity.
[0004] The utility model adopts the following technical solution: a sandwich hemp pad core, comprising two hot-melt cotton layers and a hemp layer, wherein the two hot-melt cotton layers are respectively connected to the upper and lower surfaces of the hemp layer, so that the sandwich hemp pad core forms a whole.
[0005] The hemp layer is made of hemp fiber, which has a hollow structure. The cavity is filled with oxygen, and anaerobic bacteria cannot survive. At the same time, it has good moisture conduction and breathability. The hemp layer is sandwiched by two hot-melt cotton layers to keep it in a good shape. The hot-melt cotton layer has good flexibility and is not easy to break, which provides good protection for the hemp layer and effectively prevents the hemp layer from being crushed or damaged. Therefore, the sandwich hemp pad core of this application can take into account both environmental performance and structural integrity.
[0006] Furthermore, a hot-melt connection layer is provided between the hemp layer and the hot-melt cotton layer, connecting the two layers. The hot-melt connection layer is formed by heat-melting a hot-melt film or low-melting-point fiber. Both hot-melt film and low-melting-point fiber are existing structures. The hot-melt film has excellent softness, ductility, and plasticity, is non-toxic and odorless, and is an environmentally friendly chemical product. It has a fast bonding speed after heating, saving labor and improving production capacity and work efficiency. The low-melting-point fiber is an environmentally friendly fiber that melts at a lower temperature and forms a strong bond with other fibers or materials, with good bonding properties.
[0007] Furthermore, the hemp layer is a hemp adhesive layer, and the hemp layer and the hot melt cotton layer are directly bonded together by hot melting. The hemp layer is set as the hemp adhesive layer, and the hemp layer and the hot melt cotton layer are bonded together by utilizing its own viscosity.
[0008] Furthermore, the hot melt cotton layer and the hemp layer are connected together by sewing them up and down with a knitted thread. The use of a physical connection method to connect the hot melt cotton layer and the hemp layer can ensure environmental protection and a stable structure.
[0009] Furthermore, the hemp layer has a gram weight of 220-250 g / m 2 When the gram weight is too high, the spaces between the hemp fibers become smaller, restricting the flow of air and moisture, and reducing the fabric's moisture absorption and breathability. A hemp layer with a lower gram weight has larger spaces between its fibers, which facilitates the flow of air and moisture, resulting in better moisture absorption and breathability. However, a too low gram weight can lead to insufficient strength and excessive looseness, affecting the performance of the hemp layer. Therefore, choosing the right gram weight for the hemp layer is crucial to achieving both the breathability and strength requirements of the core pad.
[0010] Furthermore, the weight of the hot melt cotton layer is 220-250g / m 2 When the gram weight is too high, the air permeability of the hot melt cotton layer becomes worse and the hardness becomes greater. When the gram weight is too low, its strength becomes worse and it cannot provide a good supporting effect after connecting the hemp layer.
[0011] Furthermore, the total thickness of the sandwich hemp mattress core is 4-6 cm. The thickness will affect the air permeability of the entire mattress, and too small a thickness will affect the comfort of use, so it is important to choose an appropriate thickness.
[0012] Furthermore, the two hot-melt cotton layers have different densities, which makes the hardness of the two sides of the cushion core different to meet different usage requirements.
[0013] The present application also provides a mattress, comprising a mattress cover and a mattress core, wherein the mattress core is the above-mentioned sandwich hemp mattress core. The mattress cover protects the mattress core to prevent it from being punctured by sharp objects.
[0014] Furthermore, the mattress cover comprises an upper layer and a lower layer, wherein the upper layer and the lower layer are connected by a binding edge, so that the upper layer and the lower layer are stably and reliably connected by the binding edge, thereby providing better protection for the mattress core built therein.
[0015] The beneficial effects of the present invention are as follows: the present application is a sandwich hemp pad core and mattress, which utilizes the hemp layer to achieve the bactericidal and antibacterial functions, and the hemp layer is clamped by two hot-melt cotton layers so that the hemp layer maintains a good shape, and the hot-melt cotton layer has good flexibility and is not easy to break, which plays a good protective role for the hemp layer and effectively prevents the hemp layer from being crushed or damaged. Therefore, the present application can take into account both environmental protection performance and structural integrity. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The following is an explanation and description of the technical solutions of the embodiments of the present invention in conjunction with the accompanying drawings of the present invention. However, the following embodiments are only preferred embodiments of the present invention and are not exhaustive. Based on the embodiments in the embodiments, other embodiments obtained by those skilled in the art without creative work are all within the scope of protection of the present invention.
[0026] Example 1
[0027] This embodiment is a sandwich hemp pad core, including two hot-melt cotton layers 1 and a hemp layer 2. The two hot-melt cotton layers 1 are respectively connected to the upper and lower surfaces of the hemp layer 2, so that the sandwich hemp pad core forms a whole.
[0028] Hemp layer 2 is made of hemp fiber, which has a hollow structure. The cavity is filled with oxygen, preventing anaerobic bacteria from surviving. It also has excellent moisture conduction and breathability. Hemp layer 2 is sandwiched between two heat-melting cotton layers 1, which helps maintain its shape. The heat-melting cotton layers 1 are flexible and resistant to breakage, providing good protection for hemp layer 2 and effectively preventing it from being crushed or damaged. Therefore, the sandwich hemp pad core of this application can achieve both environmental performance and structural integrity. Hemp layer 2 can be composed of 30% hemp fiber, 40% low-melting-point polyester fiber, and 30% 3D high-elastic fiber.
[0029] The hemp layer 2 is a hemp adhesive layer, which can be formed by mixing hemp fibers with low-melting-point fibers and heating them, or by using water-based glue, environmentally friendly resin glue or hot-melt glue in the hemp layer 2 to form a hemp adhesive layer. The hemp layer 2 and the hot-melt cotton layer 1 are directly bonded together by hot-melt. If low-melting-point fibers are provided in the hemp layer 2, the low-melting-point fibers can be connected to both the hemp fibers in the hemp layer 2 and the hot-melt cotton layer 1 after hot-melting. The adhesive has good environmental performance. In this way, the hemp adhesive layer itself has viscosity and can bond the hemp layer 2 and the hot-melt cotton layer 1 together. Similarly, using water-based glue, environmentally friendly resin glue or hot-melt glue to form a hemp adhesive layer in the hemp layer 2 also has considerable technical effects.
[0030] The hemp layer 2 has a grammage of 220-250 g / m². If the grammage is too high, the spaces between the hemp fibers will become smaller, restricting the flow of air and moisture, and reducing the fabric's moisture absorption and breathability. A hemp layer 2 with a lower grammage has larger spaces between its fibers, facilitating the flow of air and moisture, and improving moisture absorption and breathability. However, an excessively low grammage can result in insufficient strength and excessive bulk, affecting the performance of the hemp layer 2. Therefore, choosing an appropriate grammage for the hemp layer 2 is crucial to achieving both the breathability and strength requirements of the core cushion.
[0031] The weight of the hot melt cotton layer 1 is 220-250g / m2. If the weight is too high, the air permeability of the hot melt cotton layer 1 will deteriorate and the hardness will increase. If the weight is too low, its strength will deteriorate and it will not provide a good supporting effect after being connected to the hemp layer 2.
[0032] The total thickness of the sandwich hemp mattress core is 4-6 cm. The thickness will affect the air permeability of the entire mattress. Too thin a thickness will affect the comfort of use, so it is important to choose the right thickness.
[0033] The two hot-melt cotton layers 1 have different densities, which makes the hardness of the two sides of the cushion core different to meet different usage requirements.
[0034] Example 2
[0035] like Figure 3 and Figure 4As shown, this embodiment differs from embodiment 1 in that a hot-melt connection layer 3 is provided between the hemp layer 2 and the hot-melt cotton layer 1 to connect the hemp layer 2 and the hot-melt cotton layer 1. The hot-melt connection layer 3 is formed by hot-melt film or low-melting point fiber through heat melting. Both hot-melt film and low-melting point fiber are existing structures. Hot-melt film has good softness, ductility, and plasticity, and is non-toxic and odorless. It is an environmentally friendly chemical product. Its rapid bonding speed after heating can save labor and improve production capacity and work efficiency. Low-melting point fiber is an environmentally friendly fiber that can melt at a lower temperature and form a strong bond with other fibers or materials, with good bonding performance.
[0036] Example 3
[0037] like Figure 5 As shown, the difference between this embodiment and embodiment 1 is that the hot melt cotton layer 1 and the hemp layer 2 are connected together by sewing the hot melt cotton layer 1 and the hemp layer 2 together with the knitted thread 4. The use of a physical connection method to connect the hot melt cotton layer 1 and the hemp layer 2 can ensure environmental protection while ensuring a stable structure and preventing loosening.
[0038] Example 4
[0039] like Figure 6 and Figure 7 As shown, this embodiment is a mattress comprising a mattress cover 5 and a mattress core. The mattress core is the hemp core mattress of Example 1. The mattress cover 5 protects the core mattress from being punctured by sharp objects. The mattress cover 5 comprises an upper layer 51 and a lower layer 52, which are connected by a binding 53. The binding 53 forms a stable and reliable connection between the upper and lower layers 51, 52, providing good protection for the inner core mattress.
[0040] Example 5
[0041] like Figure 8 As shown, this embodiment is a mattress, which is different from Example 4 in that the mattress core is the sandwich hemp mattress core of Example 2.
[0042] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Those skilled in the art will understand that the present invention includes, but is not limited to, the contents described in the accompanying drawings and the above specific embodiments. Any modifications that do not deviate from the functional and structural principles of the present invention are intended to be included within the scope of the claims.
