Description

Technical Field

[0001] This utility model relates to a polyester fabric, specifically a tear-resistant polyester fabric. Background Technology

[0002] Polyester fabrics are widely used in clothing, home textiles, and industrial textiles due to their numerous advantages, including crispness, wrinkle resistance, easy washing and quick drying, and good shape retention. With the improvement of people's living standards and their love for outdoor sports, the outdoor products market is developing rapidly. Outdoor gear such as tents, backpacks, and waterproof jackets place higher demands on the tear resistance of fabrics. In the complex outdoor environment, fabrics may be subjected to external forces such as scratches from branches, friction from rocks, and pulling from strong winds. If the fabric's tear resistance is insufficient, it is easily damaged, affecting the safety and lifespan of outdoor gear. Therefore, it is necessary to provide a tear-resistant polyester fabric.

[0013] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0014] Combination Figure 1-2 This embodiment provides a detailed description of a tear-resistant polyester fabric, comprising: an abrasion-resistant layer 1, a tear-resistant layer 2, and a moisture-wicking and antibacterial layer 3 sequentially arranged, wherein the abrasion-resistant layer 1, the tear-resistant layer 2, and the moisture-wicking and antibacterial layer 3 are composited by an array of dot-matrix hot-melt PU adhesive; the abrasion-resistant layer 1 is woven from abrasion-resistant yarns; the tear-resistant layer 2 is a three-dimensional fabric woven from a first yarn 4, a second yarn 5, and a third yarn 6 interwoven at 60° intervals, wherein the first yarn 4, the second yarn 5, and the third yarn 6 are polyester filaments; the moisture-wicking and antibacterial layer 3 is woven from warp and weft yarns, wherein the warp yarns are moisture-wicking yarns, and the weft yarns are antibacterial yarns.

[0015] Conventional woven fabrics are made of warp and weft yarns interwoven perpendicularly. This orthogonal planar fabric can effectively transfer loads in the direction parallel to the yarns. However, when the force direction is not along the warp or weft yarn arrangement direction, the fabric's ability to resist deformation and damage decreases significantly. In contrast, a three-dimensional fabric, made of the first yarn 4, the second yarn 5, and the third yarn 6 interwoven at 60° intervals, has a more uniform load-bearing capacity in all directions. Regardless of whether the force direction is along the yarn direction, there are no obvious weak directions that resist shear deformation and shear damage. Even in thinner fabrics, the dimensional stability is very good. When subjected to normal external force impact, the fabric deforms more evenly in the circumferential direction, and it is less likely to experience localized stress concentration in two-dimensional planar fabrics that could lead to yarn breakage. Therefore, it has better tear resistance.

[0016] Furthermore, the abrasion-resistant yarn is a bio-based polyamide 56 fiber filament. The raw materials and processing of bio-based polyamide 56 fiber filament are green and environmentally friendly. Its fibers have better moisture absorption and quick-drying properties, skin-friendliness, abrasion resistance, softness, and low-temperature dyeing properties than ordinary polyamide fibers, making them suitable for use in the apparel filament field.

[0017] Furthermore, the polyester filament is a high-strength polyester filament. The breaking strength of high-strength polyester filament is typically between 5-8 cN / dtex, much higher than that of ordinary polyester filament, which allows it to withstand greater tensile forces. High-strength polyester filament also has a high elastic modulus, generally around 100-150 cN / dtex. High modulus means that the fiber is not easily deformed under stress and can maintain good shape stability, which can give the tear-resistant layer 2 good strength and tear resistance.

[0018] Furthermore, the moisture-wicking yarn is a U-shaped cross-section polyester filament. U-shaped cross-section polyester filament is a fiber produced using U-shaped spinnerets and is a differentiated fiber. The cross-section of U-shaped polyester filament resembles the English letter U. Because the fiber grooves are deep, some fibers are even flattened, causing the grooves to disappear. When this structured fiber is formed into a fabric, it easily generates more fine grooves, thus forming more capillary channels, which is very beneficial for moisture conduction. In addition, it has a large specific surface area, resulting in fabrics formed from U-shaped cross-section polyester filament with excellent moisture-wicking and quick-drying properties.

[0019] Furthermore, the antibacterial yarn is a nano-copper ion antibacterial yarn. The nano-copper ion antibacterial yarn is a 60 / 40 blend of 18.5tex viscose fiber and copper ion polyester fiber. Copper ion polyester fiber is a functional antibacterial fiber made by processing antibacterial copper materials to achieve a nano-sized particle size, then adding it to polyester spinning solution and spinning. The nano-copper ions are firmly embedded in the polyester fiber molecular structure, making it a non-leaching antibacterial fiber with long-lasting antibacterial and deodorizing effects. The high strength of copper ion polyester fiber compensates for the lower strength of viscose fiber, while the good moisture absorption of viscose fiber compensates for the lower moisture absorption of polyester fiber. Therefore, the nano-copper ion antibacterial yarn possesses both high strength and moisture-wicking breathability, along with excellent antibacterial properties.

[0020] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
