Abstract
Description
Technical Field
[0001] This utility model belongs to the field of aramid fabric manufacturing technology, specifically relating to a high-strength and wear-resistant aramid fabric structure. Background Technology
[0002] Aramid fabric, also known as Kevlar fabric, aramid fiber fabric, or aramid textile, is an insulating and heat-retaining fabric. It is a high-performance fiber fabric widely used in various fields due to its excellent physical and chemical properties. The main component of aramid fabric is aramid fiber, officially called "poly(p-phenylene terephthalamide)", a new type of high-tech synthetic fiber with excellent properties such as ultra-high strength, high density, high temperature resistance, acid and alkali resistance, and light weight. The strength of aramid fiber is 5-6 times that of steel wire, its modulus is 2-3 times that of steel wire or glass fiber, its toughness is twice that of steel wire, while its weight is only about 1 / 5 that of steel wire. At a temperature of 560 degrees Celsius, aramid fiber does not decompose or melt, exhibits good insulation and anti-aging properties, and has a long lifespan. The discovery of aramid is considered a very important historical process in the field of materials science.
[0003] Problems with existing technology:
[0004] Most aramid fabrics currently available are made from yarns of aramid material. Aramid has advantages such as fire retardancy, light weight, puncture resistance, cut resistance, abrasion resistance, heat resistance, chemical corrosion resistance, good mechanical properties, and good dielectric properties. However, during use, when aramid fabric comes into contact with other objects through friction or is subjected to mechanical stretching, the yarns on the aramid fabric reach a critical point, causing fraying or separation. This makes the aramid fabric prone to wear and breakage, reducing its overall performance and tensile strength, thus affecting its usability. Utility Model Content
[0005] The purpose of this invention is to provide a high-strength, wear-resistant aramid fabric structure that can solve the above-mentioned technical problems.
[0006] The specific technical solution adopted by this utility model is as follows:
[0007] This utility model provides a high-strength and wear-resistant aramid fabric structure, including an outer sheath, an adhesive layer, and an inner lining layer, wherein the outer sheath is bonded to the inner lining layer through the adhesive layer;
[0008] The outer sheath includes multiple upper warp yarns, multiple lower warp yarns, and weft yarns. The multiple upper warp yarns and multiple lower warp yarns are woven from the weft yarns using a twill weave process to form the outer sheath.
[0009] The lining layer includes yarn, which is knitted to form the lining layer. The yarn is soaked in an adhesive layer and bonded to the upper warp yarn, lower warp yarn, and weft yarn.
[0010] Preferably, the denier value of the upper warp is set to twice that of the lower warp.
[0011] Preferably, the upper warp yarn is made of Sovit brand 203 aramid yarn, and the lower warp yarn is made of aramid fiber yarn of aramid F-12.
[0012] Preferably, the adhesive layer is made of water-based latex.
[0013] The beneficial effects are:
[0014] 1. This utility model is formed by twill weaving of the upper warp yarn, lower warp yarn and weft yarn on the outer layer. The material used for the upper warp yarn forms a wear-resistant layer on the outer surface of the outer layer, thereby improving the wear resistance. The lower warp yarn uses its tensile strength to improve the overall strength of the aramid fabric. In this way, the overall performance of the aramid fabric can be improved and the service life can be extended.
[0015] 2. This utility model uses a knitted inner lining layer to form an elastic and soft texture. This ensures that the outer layer will not be affected by tension, thus improving the performance. Attached Figure Description

[0017] Figure 2 This is a schematic diagram of the meridional cross-sectional structure of the outer layer in this utility model.
[0018] The attached diagram lists the components represented by each number as follows:
[0019] 1. Outer layer; 11. Upper warp yarn; 12. Lower warp yarn; 13. Weft yarn; 2. Adhesive layer; 3. Inner lining layer; 31. Yarn. Detailed Implementation
[0020] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.
[0021] like Figure 1 As shown, a high-strength and wear-resistant aramid fabric structure includes an outer layer 1, an adhesive layer 2, and an inner lining layer 3. The outer layer 1 is bonded to the inner lining layer 3 through the adhesive layer 2.
[0022] The outer sheath 1 includes multiple upper warp yarns 11, multiple lower warp yarns 12, and weft yarns 13. The multiple upper warp yarns 11 and multiple lower warp yarns 12 are woven from the weft yarns 13 in a twill weave using a shuttle weaving process to form the outer sheath 1.
[0023] The inner lining layer 3 includes yarn 31, which is made of polyester yarn. The yarn 31 is woven into the inner lining layer 3 by knitting. The yarn 31 is soaked in adhesive layer 2 and bonded to the upper warp yarn 11, lower warp yarn 12 and weft yarn 13. This allows the inner lining layer 3 to have elasticity and soft texture through knitting, so that the outer covering layer 1 will not affect the inner lining layer 3 when subjected to tension, thereby improving the performance.
[0024] See attached document Figure 2 The denier value of the upper warp yarn 11 is set to twice that of the lower warp yarn 12, so that the upper warp yarn 11 protrudes from the lower warp yarn 12 after weaving. This allows the upper warp yarn 11 to be located on the outer surface of the aramid fabric. To prevent wear when in contact with other items, the warp tightness of the upper warp yarn 11 and the lower warp yarn 12 during weaving is not less than 80%, and the weft tightness of the weft yarn 13 is not less than 70%. This allows the upper warp yarn 11 to be squeezed by the weaving force after weaving, which can squeeze the weft yarn 13 between the two adjacent upper warp yarns 11 and the two lower warp yarns 12. Thus, the outer surface of the aramid fabric can be formed with a wear-resistant protective layer using the upper warp yarn 11.
[0025] Furthermore, the upper warp yarn 11 uses Sovit brand 203 aramid yarn, which can improve the wear resistance of the outer surface of the aramid fabric by utilizing the characteristics of Sovit brand 203 aramid yarn. The lower warp yarn 12 uses aramid fiber yarn of aramid F-12, which can improve the strength of the aramid fabric and enhance the tensile strength by utilizing aramid fiber yarn of aramid F-12.
[0026] Furthermore, the adhesive layer 2 uses water-based latex, which improves the adhesion between the yarn 31 and the upper warp 11, lower warp 12 and weft 13, and enhances the fixation effect of the inner lining layer 3 on the aramid fabric.
[0027] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
