Description

Technical Field

[0001] The utility model relates to the technical field of fabric preparation, and more specifically to a fabric, an upper and a shoe. Background Art

[0002] Traditionally, the fabric used to make uppers is usually mesh or leather, and its texture style is usually achieved by embossing the fabric and leather during processing, or directly by electro-embroidery, printing, etc. on the upper fabric to achieve more upper modifications. However, the texture effect obtained by embossing on leather is relatively shallow, while the texture effect obtained by electro-embroidery and printing is relatively heavy and generally feels relatively stiff, making the upper heavier, the surface of the fabric feels stiff, and the style of the upper relatively single, resulting in poor visualization.

[0003] In addition, during the processing of the upper fabric, it is necessary to go through a series of complex processes such as secondary sewing and bonding. The operation process is relatively complicated, which increases the risk of unstable quality during manual operation and results in a high defective rate.

[0004] Therefore, how to improve the visualization effect of fabrics has become a technical problem that needs to be solved urgently by those skilled in the art. Utility Model Content

[0005] In view of this, an object of the present invention is to provide a fabric to improve the visualization effect of the fabric.

[0006] Another object of the utility model is to provide an upper surface using the above-mentioned fabric.

[0007] Another object of the utility model is to provide a shoe using the upper.

[0008] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0009] A fabric, comprising:

[0010] The foam layer is provided with concave-convex patterns, and the concave-convex patterns are formed by hot pressing. The concave-convex patterns include a transparent area arranged at a concave position of the foam layer and a fluffy area arranged at a convex position of the foam layer.

[0011] Optionally, in the above fabric, a fabric layer is also included;

[0012] The fabric layer and the foam layer are bonded and connected.

[0013] Optionally, in the above fabric, the material of the fabric layer is a mesh material prepared by knitting or weaving.

[0014] Optionally, in the above fabric, the melting point of the material of the fabric layer is not lower than the melting point of the material of the foam layer.

[0015] Optionally, in the above fabric, the fabric layer and the foam layer are bonded and connected by a hot-melt film.

[0016] Optionally, in the above-mentioned fabric, the hot-melt film is a mesh film structure.

[0017] Optionally, in the above-mentioned fabric, the material of the foam layer is a thermoplastic material, and the thermoplastic material is at least one of thermoplastic polyurethane, polyamide, polyamide elastomer and thermoplastic polyester elastomer.

[0018] Optionally, in the above fabric, the thickness of the foam layer is 0.1 mm to 10 mm.

[0019] An upper surface, wherein the upper surface is cut from the fabric as described in any one of the above items.

[0020] A shoe comprises a sole and an upper, wherein the upper is the upper as described above.

[0021] The fabric provided by the utility model is provided with concave-convex patterns on the foam layer, and the concave-convex patterns are formed by heat pressing, so as to avoid a series of complicated processes such as secondary sewing and bonding during fabric processing, thereby reducing the risk of unstable quality caused by manual operation. At the same time, by forming the concave-convex patterns on the relatively soft foam layer by heat pressing, that is, forming a transparent area at the concave position and a fluffy area at the convex position, a partially semi-transparent and partially fluffy fabric is produced, which increases the visual effect.

[0022] Compared with the prior art, the fabric provided by the utility model forms concave and convex patterns on the foam layer by means of heat pressing, thus avoiding a series of complex processes such as secondary stitching and bonding in the traditional way, and reducing the risk of unstable quality caused by manual operation. At the same time, by forming a transparent area at the concave position of the foam layer and forming a fluffy area at the convex position of the foam layer, the depth control of the concave and convex patterns formed by heat pressing is more accurate compared with the traditional methods such as electric embroidery and printing. In addition, since the concave and convex patterns are formed directly by heat pressing on the foam layer, there is no need to add additional stitching, so the weight of the fabric is lighter, and the convex area is formed at the convex position of the foam layer, which increases the comfort of the hand feel and improves the visualization effect of the fabric, thereby solving the problem of the single style of the upper.

[0032] The core of the utility model is to provide a fabric to improve the visualization effect of the fabric.

[0033] Another core of the utility model is to provide an upper surface using the above fabric.

[0034] Another core of the utility model is to provide a shoe adopting the upper.

[0035] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0036] like Figures 1 to 4 As shown, the embodiment of the utility model discloses a fabric 100, including a foam layer 101. It should be noted that the fabric for traditional uppers is usually mesh or leather, and its texture style is usually achieved by embossing the fabric tissue and leather during the processing or directly by electro-embroidery, printing, etc. on the fabric of the upper to achieve more upper modifications. However, the texture effect obtained by embossing on the leather is relatively shallow, while the texture effect obtained by electro-embroidery and printing is relatively heavy and generally feels relatively stiff, which makes the upper heavier, the surface of the fabric feels stiff, and the style of the upper is relatively single, resulting in poor visualization.

[0037] In addition, during the processing of the upper fabric, it is necessary to go through a series of complex processes such as secondary sewing and bonding. The operation process is relatively complicated, which increases the risk of unstable quality during manual operation and results in a high defective rate.

[0038] The fabric 100 disclosed in the embodiment of the utility model forms concave-convex patterns on the foam layer 101 by means of heat pressing, thus avoiding a series of complicated processes such as secondary stitching and bonding in the traditional way, and reducing the risk of unstable quality caused by manual operation. At the same time, by forming a transparent area 1011 at the concave position of the foam layer 101 and forming a fluffy area 1012 at the convex position of the foam layer 101, the depth control of the concave-convex patterns formed by heat pressing is more accurate compared to the traditional methods such as electric embroidery and printing. In addition, since the concave-convex patterns are formed directly by heat pressing on the foam layer 101, there is no need to add additional stitching, so that the weight of the fabric 100 is lighter, and the fluffy area 1012 is formed at the convex position of the foam layer 101, which increases the comfort of the hand feel and improves the visualization effect of the fabric 100, thereby solving the problem of the single style of the upper.

[0039] like Figure 1 and Figure 2As shown, the foam layer 101 is provided with concavo-convex patterns, and the concavo-convex patterns are formed by hot pressing, and the concavo-convex patterns include a transparent area 1011 provided at a concave position of the foam layer 101 and a fluffy area 1012 provided at a convex position of the foam layer 101. By providing the concavo-convex patterns on the foam layer 101, and forming the concavo-convex patterns by hot pressing, a series of complex processes such as secondary sewing and bonding during the processing of the fabric 100 are avoided, thereby reducing the risk of unstable quality caused by manual operation. At the same time, by forming the concavo-convex patterns on the relatively soft foam layer 101 by hot pressing, that is, forming the transparent area 1011 at the concave position and forming the fluffy area 1012 at the convex position, a partially semi-transparent and partially fluffy fabric 100 is produced, which increases the visual effect.

[0040] Specifically, the material of the foam layer 101 is preferably a thermoplastic material, and the thermoplastic material is formed into the foam layer 101 by physical foaming. The thermoplastic material can be one of thermoplastic polyurethane, polyamide, polyamide elastomer and thermoplastic polyester elastomer, or a combination of two or more materials. The thickness of the foam layer 101 is preferably 0.1 mm to 10 mm, so that the fabric 100 can increase the three-dimensional visual effect of the concave and convex texture while reducing the weight of the fabric 100. After dissolving a gas such as carbon dioxide or nitrogen into the thermoplastic material, the gas is expanded or vaporized by reducing the pressure or increasing the temperature to form a cellular structure inside the thermoplastic material, thereby forming the foam layer 101. Then, the fabric 100 is placed in a hot pressing mold. Since there is a concave-convex structure in the hot pressing mold, when the hot pressing mold is heated and pressure is applied, the convex structure in the hot pressing mold squeezes the gas in the foam layer 101 to the surrounding area, so that a depression is formed at the convex structure in the hot pressing mold corresponding to the foam layer 101, that is, a transparent area 1011, and a convexity is formed at the concave structure in the hot pressing mold corresponding to the foam layer 101, that is, a fluffy area 1012, thereby producing a partially semi-transparent and partially fluffy fabric 100, which increases the visual effect. In addition, since the concave-convex texture of the fabric 100 is formed by hot pressing, a series of complex processes such as secondary stitching and bonding in the traditional fabric 100 processing process can be avoided, reducing the risk of unstable quality caused by manual operation. Compared with the traditional methods such as electric embroidery and printing, the different concave-convex textures formed by hot pressing can be formed by changing the concave-convex structure in the hot pressing mold, thereby solving the problem of a single style of the upper, and the depth of the texture can be controlled more accurately. In addition, since the concave and convex patterns are formed directly on the foam layer 101 by hot pressing without adding additional stitching, the weight of the fabric 100 is lighter, and the raised positions of the foam layer 101 form fluffy areas 1012, which increases the comfort of the hand and improves the visualization effect of the fabric 100.

[0041] It should be noted that the hot pressing mold is a metal mold with a concave-convex structure on the inner wall. The hot pressing mold can be a single-piece mold or a male-female mold. When the hot pressing mold is hot pressed, the pressure range is 0.1KPa~10MPa, and the processing time is 15s~15min. In addition, when heating and applying pressure to the hot pressing mold, high-frequency assistance can be used at the same time, and the heating temperature needs to be set according to the softening point and melting point of different materials.

[0042] Furthermore, if Figure 3 and Figure 4 As shown, the fabric 100 further includes a fabric layer 102, that is, the fabric 100 can be a combination of a fabric layer 102 and a foam layer 101. Specifically, the material of the fabric layer 102 can be a mesh material prepared by knitting or weaving, or can be a polyester material that is the same as the foam layer 101. When the material of the fabric layer 102 is a mesh material, in order to connect the fabric layer 102 and the foam layer 101, the fabric layer 102 and the foam layer 101 are bonded and connected by a hot melt film 103, as shown in FIG. Figure 3 and Figure 4 As shown, the hot melt film 103 can be a mesh film structure or a non-porous film structure. In order to ensure that when the fabric 100 is subjected to hot pressing treatment, when the foam layer 101 softens, the fabric layer 102 can provide bottom support for the foam layer 101, the melting point of the material of the fabric layer 102 is not lower than the melting point of the material of the foam layer 101. Of course, when the fabric layer 102 and the foam layer 101 are both made of polyester material, such as the fabric layer 102 is made of polyester material and the foam layer 101 is made of thermoplastic polyurethane elastomer, the hot melt film 103 does not need to be provided, and the fabric layer 102 and the foam layer 101 can be bonded and connected by hot pressing.

[0043] The embodiment of the utility model further discloses an upper surface, which is cut from the fabric 100 disclosed in the above embodiment. Therefore, the fabric of the upper surface has all the technical effects of the above fabrics, which will not be described in detail herein.

[0044] The utility model also discloses a shoe, including a sole and an upper, and the sole and the upper can be connected by adhesive bonding or sewing. The upper is the upper disclosed in the above embodiment, so the upper has all the technical effects of the above upper, which will not be described in detail herein.

[0045] like Figure 5 As shown, the embodiment of the utility model also discloses a fabric preparation method, which is a fabric preparation method for the fabric disclosed in the above embodiment, so the fabric prepared by the fabric preparation method has all the technical effects of the above fabrics, which will not be described in detail herein. The fabric preparation method includes:

[0046] Step S100, preparing a foam layer 101;

[0047] The thermoplastic material is physically foamed to form the foam layer 101. Specifically, after carbon dioxide or nitrogen is dissolved in the thermoplastic material, the gas is expanded or vaporized by reducing the pressure or increasing the temperature to form a cellular structure inside the thermoplastic material, thereby forming the foam layer 101.

[0048] Step S101, hot pressing treatment;

[0049] The foam layer 101 is subjected to a hot pressing process to form a finished fabric 100, wherein the fabric 100 includes concave-convex patterns. Specifically, the fabric 100 is placed in a hot pressing mold, and since there is a concave-convex structure forming the concave-convex patterns in the hot pressing mold, when the hot pressing mold is heated and pressure is applied, the convex structure in the hot pressing mold squeezes the gas in the foam layer 101 to the surrounding area, thereby forming a depression at the convex structure in the hot pressing mold corresponding to the foam layer 101, i.e., a transparent area 1011, and forming a convexity at the concave structure in the hot pressing mold corresponding to the foam layer 101, i.e., a fluffy area 1012, thereby producing a partially semi-transparent and partially fluffy fabric 100.

[0050] In a specific embodiment, the foam layer 101 is a sheet of thermoplastic polyurethane foam obtained by physical foaming, the thickness of the thermoplastic polyurethane foam is 1 mm, the melting point of thermoplastic polyurethane is 160° C. The thermoplastic polyurethane foam is placed in a hot pressing mold with a designed concave-convex structure, and hot pressing is assisted by high frequency. The hot pressing temperature is 150° C., the pressure applied to the hot pressing mold is 1 MPa, and the hot pressing time is 1 min, thereby obtaining a fabric 100 having only the foam layer 101 and concave-convex patterns.

[0051] like Figure 6 As shown, the embodiment of the utility model also discloses a fabric preparation method, comprising:

[0052] Step S200, obtaining the fabric layer 102;

[0053] The material of the fabric layer 102 may be a mesh material prepared by knitting or weaving, or may be the same material as the foam layer 101 , such as thermoplastic polyurethane elastomer.

[0054] Step S201, preparing a foam layer 101;

[0055] A foam layer 101 is prepared on the fabric layer 102. Specifically, the thermoplastic material is physically foamed to form the foam layer 101. Specifically, after a gas such as carbon dioxide or nitrogen is dissolved in the thermoplastic material, the gas is expanded or vaporized by reducing the pressure or increasing the temperature to form a cellular structure inside the thermoplastic material, thereby forming the foam layer 101. Furthermore, the foam layer 101 and the fabric layer 102 are connected by bonding. When the fabric layer 102 is made of mesh material, in order to connect the fabric layer 102 and the foam layer 101, a hot melt film 103 is bonded between the fabric layer 102 and the foam layer 101, such as Figure 3 and Figure 4 When both the fabric layer 102 and the foam layer 101 are made of polyester material, for example, the fabric layer 102 is made of polyester material and the foam layer 101 is made of thermoplastic polyurethane elastomer, the hot melt film 103 is not required, and the fabric layer 102 and the foam layer 101 can be bonded and connected by hot pressing.

[0056] Step S202, hot pressing treatment;

[0057] The fabric 100 is placed in a hot pressing mold. Since the hot pressing mold has a concave-convex structure that forms concave-convex patterns, when the hot pressing mold is heated and pressure is applied, the convex structure in the hot pressing mold squeezes the gas in the foam layer 101 to the surrounding area, thereby forming a depression at the convex structure in the hot pressing mold corresponding to the foam layer 101, namely the transparent area 1011, and forming a convexity at the concave structure in the hot pressing mold corresponding to the foam layer 101, namely the fluffy area 1012, thereby producing a partially semi-transparent and partially fluffy fabric 100.

[0058] In a specific embodiment, the foam layer 101 is a sheet of thermoplastic polyurethane foam obtained by physical foaming, the thickness of the thermoplastic polyurethane foam is 0.1 mm, the melting point of thermoplastic polyurethane is 160°C, the sheet of thermoplastic polyurethane foam, the hot melt film 103 with a mesh membrane structure and the fabric layer 102 of polyester material are stacked in sequence and put into a hot pressing mold, assisted by high frequency hot pressing, the hot pressing temperature is 155°C, the pressure applied to the hot pressing mold is 100kPa, and the hot pressing time is 30s. After hot pressing, it is taken out to obtain a fabric 100 having both the fabric layer 102 and the foam layer 101, and having concave and convex patterns formed on the foam layer 101.

[0059] In another specific embodiment, the foam layer 101 is a sheet of thermoplastic polyamide elastomer foam obtained by physical foaming, the thickness of the thermoplastic polyamide elastomer foam is 0.1 mm, the melting point of the thermoplastic polyamide elastomer is 170°C, the sheet of thermoplastic polyamide elastomer foam, the hot melt film 103 with a mesh membrane structure and the fabric layer 102 of polyester material are sequentially stacked and placed in a hot pressing mold, assisted by high frequency hot pressing, the hot pressing temperature is 165°C, the pressure applied to the hot pressing mold is 10MPa, and the hot pressing time is 15s. After hot pressing, it is taken out to obtain a fabric 100 having both the fabric layer 102 and the foam layer 101, and having concave and convex patterns formed on the foam layer 101.

[0060] In another specific embodiment, the foam layer 101 is a sheet of thermoplastic polyester elastomer foam obtained by physical foaming, the thickness of the thermoplastic polyester elastomer foam is 0.1 mm, the melting point of the thermoplastic polyester elastomer is 170°C, the sheet of thermoplastic polyester elastomer foam, the hot melt film 103 with a non-porous membrane structure and the fabric layer 102 of polyester material are stacked in sequence and put into a hot pressing mold, assisted by high frequency hot pressing, the hot pressing temperature is 165°C, the pressure applied to the hot pressing mold is 10MPa, and the hot pressing time is 15s. After hot pressing, it is taken out to obtain a fabric 100 having both the fabric layer 102 and the foam layer 101, and having concave and convex patterns formed on the foam layer 101.

[0061] In another specific embodiment, the foam layer 101 is a sheet of thermoplastic polyester elastomer foam obtained by physical foaming, the thickness of the thermoplastic polyester foam is 0.5 mm, the melting point of thermoplastic polyester is 170°C, the sheet of thermoplastic polyester elastomer foam and the polyester fabric layer 102 are stacked in sequence and put into a hot pressing mold, assisted by high frequency hot pressing, the hot pressing temperature is 150°C, the pressure applied to the hot pressing mold is 10MPa, and the hot pressing time is 5min. After hot pressing, it is taken out to obtain a fabric 100 having both the fabric layer 102 and the foam layer 101, and having concave and convex patterns formed on the foam layer 101.

[0062] Of course, a fabric layer 102 may also be provided on the fabric 100. Specifically, a heat pressing treatment is first performed on the foam layer 101 to form a concave-convex pattern, and then the foam layer 101 and the fabric layer 102 are bonded together, thereby obtaining a fabric 100 having both the fabric layer 102 and the foam layer 101, and the concave-convex pattern is formed on the foam layer 101.

[0063] The fabric preparation method disclosed in the embodiment of the utility model uses a hot pressing mold and a mesh composite form to perform hot pressing treatment on the thermoplastic material, thereby forming a fabric preparation with a partially semi-transparent and partially fluffy structure. At the same time, the fabric with concave and convex patterns is obtained directly through a one-step hot pressing method, which can avoid a series of complex processes such as secondary sewing and bonding, simplify the operation process, reduce the risk of unstable quality during manual operation, and help reduce the defective rate. In addition, the cover formed by the fabric 100 prepared by this method has a certain unique appearance visual style.
