Description

Technical Field

[0001] The utility model belongs to the technical field of functional fabrics and relates to a wear-resistant light-shielding composite fabric. Background Art

[0002] Blackout fabrics are fabrics used to block sunlight and light, and are functional auxiliary fabrics. In existing blackout fabrics, the blackout layer as the core is easily worn out by friction with the outside world during daily use, thereby affecting its blackout effect.

[0003] For example, CN201921925230.3 discloses a flame-retardant, light-shielding, environmentally friendly curtain fabric, comprising an outer fabric layer, an intermediate fabric layer, and an inner fabric layer connected in sequence from top to bottom, wherein the outer fabric layer is a flame-retardant layer, the intermediate fabric layer is a waterproof layer, and the inner fabric layer is a light-shielding layer. This patent ensures the light-shielding effect by coating the surface of the intermediate fabric layer with a light-shielding coating, but the light-shielding layer in the form of a coating on the surface is easily worn and fallen off, thereby affecting its light-shielding effect. Utility Model Content

[0004] The purpose of the utility model is to provide a wear-resistant shading composite fabric to solve the problem that the existing shading fabric is easy to wear and tear, resulting in its performance being damaged.

[0005] The purpose of the utility model can be achieved through the following technical solutions:

[0006] A wear-resistant light-shielding composite fabric comprises a light-shielding layer and a wear-resistant layer respectively compounded on the upper and lower surfaces of the light-shielding layer, wherein the light-shielding layer is formed by interweaving light-shielding yarns as warp and weft yarns respectively, and the wear-resistant layer is a fabric layer formed by interweaving wear-resistant yarns as warp and weft yarns respectively and having holes evenly distributed therein.

[0007] Furthermore, the shading layer is a thick and dense fabric layer formed by floating and sinking woven shading yarns. Specifically, the shading layer is woven in a floating and sinking manner in which each warp yarn passes through one weft yarn and then presses one weft yarn.

[0008] Furthermore, in the wear-resistant layer, the warp yarns are divided into first warp yarns and second warp yarns, and the weft yarns are divided into first weft yarns and second weft yarns, each second warp yarn and two first warp yarns form a group of warp yarn units, and each second weft yarn and two first weft yarns form a group of weft yarn units, and a group of warp yarn units and a group of weft yarn units are interwoven to form a fabric unit.

[0009] In the same fabric unit, two first warp yarns are located on both sides of the second warp yarn, and each first warp yarn is interwoven with the weft yarn in a "one over one press one" or "press one over one" manner. The two first warp yarns have the same weaving direction as the weft yarns, and each second warp yarn is pressed above the three weft yarns of the weft yarn unit or below the three weft yarns of the weft yarn unit (that is, in the fabric structure, the second warp yarn and the weft yarn are interwoven in a "three over three press three" manner).

[0010] In two adjacent fabric units, the weaving directions of the first warp yarns and the weft yarns are opposite, and the weaving directions of the second warp yarns and the weft yarns are opposite.

[0011] Furthermore, in the same fabric unit, when the first warp yarn is interwoven in a manner of passing over a first weft yarn, pressing a second weft yarn, and then passing over a first weft yarn (i.e. passing one, pressing one, and then passing one again), the second warp yarn is pressed on top of three weft yarns.

[0012] Furthermore, in the same fabric unit, when the first warp yarn is interwoven in a floating and sinking manner of pressing a first weft yarn, passing a second weft yarn, and then pressing a first weft yarn (i.e. pressing one, passing one, and then pressing one again), the second warp yarn is located below the three weft yarns.

[0013] Furthermore, the second warp yarn and the second weft yarn are both composited by a core yarn and reinforcing fibers wound around the core yarn.

[0014] More preferably, the core yarn is made of 40D acrylic fiber;

[0015] The reinforcing fibers are 32S carbon fiber yarns.

[0016] In the above more preferred embodiment, there are two or more reinforcing fibers.

[0017] Furthermore, the first warp yarn and the first weft yarn are formed by composite entanglement of nylon fiber and bamboo fiber.

[0018] Furthermore, the thickness of the composite fabric is 0.2-0.5 mm.

[0019] Compared with the prior art, the utility model has the following advantages:

[0020] (1) The light-shielding layer is interwoven with light-shielding yarns having a light-shielding effect. In this way, it not only has good light-shielding performance, but also has good air permeability. In addition, a fabric layer with holes distributed on both sides of the light-shielding layer is compounded as a wear-resistant layer, which can effectively protect the light-shielding layer from external friction, thereby maintaining the durability of the light-shielding performance.

[0021] (2) The wear-resistant layer introduces highly wear-resistant polyester fiber and highly antibacterial bamboo fiber as warp and weft yarns, which can effectively improve the overall wear-resistant and antibacterial properties, and is particularly suitable for use in light-shielding fabrics. At the same time, the second warp yarn and the second weft yarn use reinforced composite fibers, which can also improve the strength and durability of the wear-resistant layer.

[0027] The present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments. This embodiment is implemented based on the technical solution of the present invention, and provides a detailed implementation method and a specific operation process, but the protection scope of the present invention is not limited to the following embodiments.

[0028] In the following examples, unless otherwise specified, raw materials or processing techniques are conventional commercially available raw materials or conventional processing techniques in the art.

[0029] Embodiment 1:

[0030] In order to solve the problem that the existing shading fabric is easy to wear and tear, resulting in its performance being damaged, the present embodiment provides a wear-resistant shading composite fabric, whose structure is as follows: Figure 1 and Figure 2 As shown, it includes a shading layer 1, and a wear-resistant layer 2 respectively compounded on the upper and lower surfaces of the shading layer 1, the shading layer 1 is formed by shading yarns interwoven as warp and weft yarns, and the wear-resistant layer 2 is a fabric layer with evenly distributed holes formed by wear-resistant yarns interwoven as warp and weft yarns.

[0031] In this embodiment, the shading yarn can be made of textile fibers with shading effects commonly used in the art, such as commercially available dark-colored UV-proof fibers, etc., or it can be prepared using the technology reported in existing public literature, such as CN206768481U, etc. This part belongs to the existing conventional technology and is not protected by the present utility model.

[0032] The shading layer 1 is made of a thick and dense fabric layer formed by floating and sinking woven shading yarns. Specifically, in the shading layer 1, the shading layer is woven in a floating and sinking manner in which each warp yarn passes through a weft yarn and then presses a weft yarn. The fabric layer serving as the shading layer 1 can effectively ensure its shading effect due to its dense fabric structure and in combination with specific shading yarns.

[0033] Please see again Figure 2 As shown, in the wear-resistant layer 2, the warp yarns are divided into the first warp yarns 21 and the second warp yarns 22, and the weft yarns are divided into the first weft yarns 23 and the second weft yarns 24. Each second warp yarn 22 and two first warp yarns 21 form a group of warp yarn units, and each second weft yarn 24 and two first weft yarns 23 form a group of weft yarn units. A group of warp yarn units and a group of weft yarn units are interwoven to form a fabric unit.

[0034] In the same fabric unit, two first warp yarns 21 are located on both sides of the second warp yarn 22, and each first warp yarn 21 is interwoven with the weft yarn in a floating and sinking manner in a "one over one press one" or "press one over one" manner. The two first warp yarns 21 have the same weaving direction as the weft yarn, and each second warp yarn 22 is pressed above the three weft yarns of the weft yarn unit or is located below the three weft yarns of the weft yarn unit (that is, in the fabric structure, the second warp yarn 22 and the weft yarn are interwoven in a floating and sinking manner in a three over three press three manner).

[0035] In two adjacent fabric units, the weaving directions of the first warp yarns 21 and the weft yarns are opposite, and the weaving directions of the second warp yarns 22 and the weft yarns are opposite.

[0036] Things to note, as Figure 2 As shown, in the same fabric unit, when the first warp yarn 21 floats and sinks and interweaves in the manner of passing through a first weft yarn 23, pressing a second weft yarn 24, and passing through another first weft yarn 23 (i.e. passing through one, pressing one, and then passing through one), the second warp yarn 22 is pressed on top of three weft yarns;

[0037] In the same fabric unit, when the first warp yarn 21 is interwoven in a manner of pressing a first weft yarn 23, passing a second weft yarn 24, and then pressing a first weft yarn 23 (i.e. pressing one, passing one, and then pressing one again), the second warp yarn 22 is located below the three weft yarns.

[0038] When the wear-resistant layer 2 is interwoven using the above weaving method, the second warp yarn 22 and the second weft yarn 24 in the fabric structure will force the first warp yarn 21 and the first weft yarn 23 in the corresponding warp yarn unit or weft yarn unit to move closer to the second warp yarn 22 and the second weft yarn 24, respectively, thereby forming a gap between two adjacent warp yarn units and two adjacent weft yarn units, thereby causing evenly distributed holes to appear in the entire fabric structure, thereby ensuring the air permeability of the composite fabric and not affecting the protection of the wear-resistant layer 2 on the shading layer 1.

[0039] In addition, in order to further improve the strength and durability of the wear-resistant layer 2, in this embodiment, the second warp yarn 22 and the second weft yarn 24 are both composited by a core yarn and a reinforcing fiber wound on the core yarn. The core yarn is made of 40D acrylic fiber; the reinforcing fiber is made of 32S carbon fiber. At the same time, the above-mentioned reinforcing fibers can be provided with more than two as needed. The first warp yarn 21 and the first weft yarn 23 are made of nylon fiber and bamboo fiber composite intertwined, which can improve their long-term antibacterial properties, etc., and are particularly suitable for occasions where light-shielding fabrics are applicable.

[0040] The thickness of the composite fabric obtained by the above method is about 0.2-0.5mm, which is light and thin as a whole, and has good air permeability and shading effect. At the same time, the composite effect of the wear-resistant fabric layer on the outer surface and the core shading layer 1 is natural, coordinated and beautiful, and high-end and classy.

[0041] The above description of the embodiments is to facilitate the understanding and use of the utility model by those skilled in the art. It is obvious that those familiar with the art can easily make various modifications to these embodiments and apply the general principles described herein to other embodiments without creative work. Therefore, the utility model is not limited to the above embodiments, and improvements and modifications made by those skilled in the art based on the disclosure of the utility model without departing from the scope of the utility model should be within the scope of protection of the utility model.
