Description

Technical Field

[0001] This application relates to the technical field of cushioning materials, and particularly to a cushioning material. Background Art

[0002] In the prior art, the structure of a commonly used cushioning material is as Figure 1 shown. This cushioning material is a laminated composite material. The structure of this cushioning material generally includes: a flat layer a and layer c, and a layer b with spaced curved supports disposed between layer a and layer c. Since a large number of cavities are provided in layer b, it can play a role in buffering and energy absorption.

[0003] However, the material of the above cushioning material in the prior art is usually cardboard or resin board. The cushioning material made of cardboard is mostly used once, and the honeycomb board - like cushioning material made of resin board generally also has only a limited number of uses, is difficult to be reused for a long time, and has poor compressive resilience. In addition, after the above cushioning material is subjected to impact and / or extrusion, material damage is likely to occur, and most of the structures in the support layer cannot return to their original state. Therefore, the buffering effect is the largest when first subjected to impact, and the buffering effect becomes worse and worse as the number of subsequent impacts increases, and the compressive resilience is poor. In addition, if it is a cushioning material made of paper, it will even cause the buffering performance to fail after being affected by moisture, so it is not resistant to humid environments. Utility Model Content

[0004] In view of this, the present utility model provides a cushioning material, which can better resist external impacts and extrusion, and has characteristics such as impact resistance and easy resilience recovery after being impacted.

[0005] The technical solution of the present utility model is specifically implemented as follows:

[0006] A cushioning material, which includes: a first composite layer, a first fabric surface layer, an intermediate spacer layer, a second fabric surface layer, and a second composite layer;

[0007] The top of the first fabric surface layer is adhered to the bottom of the first composite layer;

[0008] The top of the intermediate spacer layer is connected to the bottom of the first fabric surface layer; the bottom of the intermediate spacer layer is connected to the top of the second fabric surface layer;

[0009] The bottom of the second fabric surface layer is adhered to the top of the second composite layer;

[0010] Both the first fabric surface layer and the second fabric surface layer are first knitted fabric layers formed by using a first type of silk thread and knitting loops simultaneously with one row or more rows of warp threads and interlacing and knitting with each other;

[0011] The middle spacer layer is a second knitted fabric layer knitted by using an independent comb bar pair of second type of silk threads.

[0012] Preferably, the material of the first type of thread is one or more materials selected from polyester, polypropylene, polyamide, polyacrylonitrile, polyvinyl chloride, polyurethane and polyethylene.

[0013] Preferably, the first type of thread is polyester filament.

[0014] Preferably, the second thread is a continuous monofilament yarn;

[0015] The plurality of monofilament yarns in the second knitted fabric layer form an upright structure, and the upper and lower ends of the upright structure are connected to the first fabric surface layer and the second fabric surface layer respectively.

[0016] Preferably, the diameter of the monofilament yarn ranges from 0.055 mm to 0.4 mm.

[0017] Preferably, the material of the second thread is one or more materials selected from the group consisting of polyester, polypropylene, polyamide, polyacrylonitrile, polyvinyl chloride, polyurethane and polyethylene.

[0018] Preferably, the first composite layer and the second composite layer are made of hard resin.

[0019] Preferably, the second type of yarn is a continuous soft multifilament yarn.

[0020] Preferably, the first composite layer and the second composite layer are made of soft surface material.

[0021] As can be seen from the above, in the buffer material of the present invention, since the middle spacer layer can be woven using continuous monofilament yarn, and the monofilament yarn is relatively stiff, its hardness and toughness can produce a bending rebound effect similar to that of an elastic rod. Therefore, the large number of upright monofilament yarns in the middle spacer layer enables the middle spacer layer to support the upper and lower surface layers, so that the three-dimensional fabric (i.e., the buffer material) finally formed has good support and compression resilience, so that it can better resist external impact and extrusion, and has the characteristics of impact resistance, easy rebound recovery after impact, and is moisture-resistant and durable, and can be reused for a long time, so it can be used to make pads, containers or packaging materials, etc. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] To make the technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0025] Figure 2 It is a schematic structural diagram of the buffer material in a specific embodiment of the present application. As Figure 2 shown, the buffer material in a specific embodiment of the present application may include: a first composite layer 11, a first fabric surface layer 12, an intermediate spacer layer 13, a second fabric surface layer 14, and a second composite layer 15;

[0026] The top of the first fabric surface layer 12 is attached to the bottom of the first composite layer 11;

[0027] The top of the intermediate spacer layer 13 is connected to the bottom of the first fabric surface layer 12; the bottom of the intermediate spacer layer 13 is connected to the top of the second fabric surface layer 14;

[0028] The bottom of the second fabric surface layer 14 is attached to the top of the second composite layer 15;

[0029] Both the first fabric surface layer 12 and the second fabric surface layer 14 are first knitted fabric layers formed by using the first type of silk thread and simultaneously knitting loops with one row or multiple rows of warp threads and interlacing with each other;

[0030] The intermediate spacer layer 13 is a second knitted fabric layer formed by knitting the second type of silk thread with an independent comb.

[0031] In the technical solution of the present application, the above buffer material has a total of five layers, and the intermediate spacer layer is knitted by an independent comb. This independent comb shuttles back and forth to lay yarns between two needle beds. On the one hand, it can participate in the knitting of the upper and lower surfaces (i.e., the first fabric surface layer and the second fabric surface layer), and on the other hand, it can form an upright structure, thereby connecting the upper and lower first fabric surface layer and the second fabric surface layer.

[0032] In addition, in the technical solution of the present application, the above buffer material can be realized through a variety of specific implementation methods. The following will take several of these specific methods as examples to introduce the technical solution of the present application in detail.

[0033] In addition, as an example, in a specific embodiment of the present application, the material of the first type of silk thread can be one or more of polyester, polypropylene, polyamide, polyacrylonitrile, polyvinyl chloride, polyurethane, and polyethylene.

[0034] For example, as an example, in a specific embodiment of the present application, the first type of silk thread can be polyester filament, or other suitable silk threads.

[0035] In addition, as an example, in a specific embodiment of the present application, the second thread can be a continuous monofilament yarn;

[0036] The plurality of monofilament yarns in the second knitted fabric layer form an upright structure, and the upper and lower ends of the upright structure are connected to the first fabric surface layer 12 and the second fabric surface layer 14 respectively.

[0037] In addition, as an example, in a specific embodiment of the present application, the material of the second thread can be one or more materials selected from polyester, polypropylene, polyamide, polyacrylonitrile, polyvinyl chloride, polyurethane and polyethylene.

[0038] In the technical solution of the present application, the above-mentioned intermediate spacer layer uses continuous monofilament yarn (that is, a continuous filament spun by a single-hole spinneret), and the monofilament yarn is relatively stiff, and its hardness and toughness can produce a bending rebound effect similar to that of an elastic rod. Therefore, the large number of upright monofilament yarns in the intermediate spacer layer enables the intermediate spacer layer to support the upper and lower surface layers, so that the three-dimensional fabric (that is, the buffer material) finally formed has excellent support and pressure rebound elasticity, so that it can better resist external impact and extrusion, and can be used to make pads, containers or packaging materials, etc.

[0039] In addition, as an example, in a specific embodiment of the present application, the diameter of the monofilament yarn ranges from 0.055 mm to 0.4 mm.

[0040] The larger the diameter of the monofilament yarn, the greater its hardness, its support performance and bending rebound effect are also stronger. Therefore, the diameter of the monofilament yarn can be predetermined according to the needs of the actual application scenario.

[0041] In addition, as an example, in a specific embodiment of the present application, the first composite layer 11 and the second composite layer 15 can be made of hard resin or other suitable materials.

[0042] The first composite layer and the second composite layer made of hard resin can be combined with the first fabric surface layer, the intermediate spacer layer, and the second fabric surface layer to form a cushioning material with two flat and hard surfaces, support and resilience between layers, such as Figure 2 shown.

[0043] In addition, as an example, in a specific embodiment of the present application, the second type of thread can be a continuous soft multifilament yarn (the multifilament yarn is a continuous thread composed of multiple, for example, dozens to hundreds of single fibers).

[0044] By using the multifilament yarn, the three-dimensional fabric finally produced can be made soft and easy to fold.

[0045] In addition, as an example, in a specific embodiment of the present application, the first composite layer 11 and the second composite layer 15 can be made of a soft surface material, or can be made of other suitable materials.

[0046] The first composite layer and the second composite layer made of the soft surface material can be combined with a fabric layer made of continuous soft multifilament yarn to form an air-filled cushioning material with a closed periphery.

[0047] When making the above-mentioned peripherally closed inflatable cushioning material, a three-dimensional woven fabric including a first fabric surface layer 12, an intermediate spacer layer 13 and a second fabric surface layer 14 can be formed first, and then the top of the first fabric surface layer and the bottom of the second fabric surface layer 14 are coated with corresponding soft surface materials (for example, resin materials, etc.), and then a hot molding operation process is performed. When performing the hot molding operation process, a corresponding temperature can be selected so that the second type of silk thread (for example, continuous soft multifilament yarn, etc.) in the intermediate spacer layer 13 is close to a molten state. Under the action of pressure in the hot molding operation process, the first fabric surface layer 12, the intermediate spacer layer 13 and the second fabric surface layer 14 will be bonded together to form a peripherally closed cushioning material. Therefore, the peripherally closed cushioning material formed in the above manner can make the final product structure very stable.

[0048] In addition, as an example, in a specific embodiment of the present application, the first composite layer 11 and the second composite layer 15 can be made of the same material or different materials.

[0049] In addition, as an example, in a specific embodiment of the present application, the first fabric surface layer 12 and the second fabric surface layer 14 can be made of the same material or different materials.

[0050] In addition, as an example, in a specific embodiment of the present application, the weaving structure of the first fabric surface layer 12 and the second fabric surface layer 14 can be: a warp plain structure, a warp satin structure or a heavy warp structure.

[0051] To sum up, in the technical solution of the present application, since the above-mentioned intermediate spacer layer can be woven using continuous monofilament yarn, and the monofilament yarn is relatively stiff, its hardness and toughness can produce a bending rebound effect similar to that of an elastic rod. Therefore, the large number of upright monofilament yarns in the intermediate spacer layer enables the intermediate spacer layer to support the upper and lower surface layers, so that the three-dimensional fabric (i.e., the buffer material) finally formed has good support and pressure rebound resilience, so that it can better resist external impact and extrusion, and has the characteristics of impact resistance, easy rebound recovery after impact, and is moisture-resistant and durable, and can be reused for a long time, so it can be used to make pads, containers or packaging materials, etc.

[0052] In addition, the above-mentioned intermediate spacer layer can also be woven from continuous soft multifilament yarns, and the first composite layer and the second composite layer can be made of soft skin materials, so as to form a peripherally enclosed inflatable cushioning material. Therefore, the technical solution of the present application can be used to match different usage environments by using different materials, and thus can be used to manufacture hard case or soft case materials, with diverse uses.

[0053] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the scope of protection of the present utility model.
