Abstract
Description
Technical Field
[0001] This utility model relates to the field of textile fabric technology, specifically to a tear-resistant polyester fabric structure with a hydrophobic interwoven composite layer. Background Technology
[0002] With the rapid development of textile materials technology, polyester fabric has been widely used in clothing manufacturing, industrial protection, and other fields due to its excellent abrasion resistance and high strength. Especially in applications such as outdoor sportswear and protective workwear, higher performance requirements are placed on the material.
[0003] Existing polyester fabrics primarily improve their performance by increasing fiber weave density or adding coatings. While traditional techniques enhance the strength of polyester fabrics to some extent, they still have significant shortcomings in practical use: Firstly, conventional hydrophobic coatings reduce the fabric's breathability and softness, and the coating is prone to wear and peeling; secondly, simply increasing fiber density, while improving tear resistance, leads to fabric stiffness and increased weight. More importantly, when polyester fabrics are in humid environments, water absorption significantly reduces their performance: absorbing water not only increases weight but also reduces breathability, and moisture weakens the bond between fibers, further deteriorating tear resistance. These technical deficiencies severely limit the application of polyester fabrics in harsh environments.
[0004] In view of the technical shortcomings of existing polyester fabrics in terms of hydrophobicity and tear resistance, especially the problem of performance degradation in humid environments, this utility model proposes a novel composite structure polyester fabric, which aims to solve the technical problems of hydrophobicity and tear resistance at the same time. Utility Model Content
[0005] To address the shortcomings of existing technologies, this invention provides a tear-resistant polyester fabric structure with a hydrophobic interwoven composite layer, thus solving the aforementioned problems.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a tear-resistant polyester fabric structure with a hydrophobic interwoven composite layer, comprising: The base fabric layer is woven from polyester fibers; The hydrophobic interwoven composite layer is formed by three-dimensional interweaving of hydrophobic fibers and polyester fibers, wherein the hydrophobic fibers form a continuous hydrophobic network structure. A gradient transition zone is provided between the base fabric layer and the hydrophobic interwoven composite layer to form a gradient change in fiber density and composition.
[0007] Preferably, the hydrophobic fiber is selected from fluorocarbon modified polyester fiber or silane modified polyester fiber, and its contact angle is ≥125°.
[0008] Preferably, the weight blending ratio of the hydrophobic fiber to the polyester fiber is 15%-35%.
[0009] Preferably, the thickness of the hydrophobic interwoven composite layer is 0.1-0.3 mm.
[0010] Preferably, the width of the gradient transition region is 0.5-1.5 mm.
[0011] Preferably, in the hydrophobic interwoven composite layer, one hydrophobic fiber is inserted every 2-4 polyester fibers in the warp direction, and one hydrophobic fiber is inserted every 3-5 polyester fibers in the weft direction.
[0012] Preferably, the hydrophobic fibers and polyester fibers in the hydrophobic interwoven composite layer form an anchoring structure at the interlacing points.
[0013] Preferably, the warp density of the base fabric layer is 80-120 threads / inch, and the weft density is 60-100 threads / inch.
[0014] Preferably, it also includes a low surface energy finishing agent disposed on the surface of the hydrophobic interwoven composite layer, the amount of which is 0.5%-2% of the fabric weight.
[0015] Beneficial effects This invention provides a tear-resistant polyester fabric structure with a hydrophobic interwoven composite layer. It has the following beneficial effects: 1. Durable hydrophobic properties: Through a three-dimensional continuous hydrophobic network structure, it can maintain excellent hydrophobic properties even after the surface finishing agent is worn away, solving the problem of poor durability of traditional coated fabrics.
[0016] 2. Enhanced tear resistance: The special fiber interlacing structure and anchoring design significantly improve the fabric's tear resistance, especially maintaining high strength in humid environments.
[0017] 3. Superior comfort: The optimized fiber arrangement and gradient transition design maintain the softness and breathability of the fabric while ensuring performance, thus improving wearing comfort.

[0019] Figure 1 Here is a schematic diagram of the structure of this utility model: In the diagram: 1. Base fabric layer, 2. Hydrophobic interwoven composite layer, 3. Gradient transition zone. Detailed Implementation
[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Please see Figure 1 This utility model provides a technical solution: a tear-resistant polyester fabric structure with a hydrophobic interwoven composite layer, comprising: Base fabric layer 1 is woven from polyester fibers. As the basic support structure of the entire fabric, base fabric layer 1 is woven from conventional polyester fibers, providing the fabric with basic mechanical properties and structural stability. Polyester fibers can include, but are not limited to, synthetic fibers with high strength properties such as polyethylene terephthalate (PET) fibers and polypropylene terephthalate (PPT) fibers. The fiber form can be filaments, staple fibers, or a combination thereof.
[0022] The base fabric layer 1 can be woven using basic structures such as plain weave, twill weave, or satin weave, or it can be woven using variations or composite structures to meet the requirements of different application scenarios for the basic properties of the fabric.
[0023] The base fabric layer 1 has a warp density of 80-120 threads / inch and a weft density of 60-100 threads / inch.
[0024] The hydrophobic interwoven composite layer 2 is formed by three-dimensional interweaving of hydrophobic fibers and polyester fibers, wherein the hydrophobic fibers form a continuous hydrophobic network structure. The hydrophobic fibers are selected from fluorocarbon-modified polyester fibers or silane-modified polyester fibers, with a contact angle ≥125°. The weight blending ratio of the hydrophobic fibers to the polyester fibers is 15%-35%. The thickness of the hydrophobic interwoven composite layer 2 is 0.1-0.3 mm. In the hydrophobic interwoven composite layer 2, one hydrophobic fiber is inserted every 2-4 polyester fibers in the warp direction and one hydrophobic fiber is inserted every 3-5 polyester fibers in the weft direction. The hydrophobic fibers and polyester fibers in the hydrophobic interwoven composite layer 2 form an anchoring structure at the interweaving points.
[0025] The hydrophobic interwoven composite layer 2 is the core innovative structure of this invention. It forms a composite structure with special functions by three-dimensionally interweaving hydrophobic fibers and polyester fibers. Three-dimensional interweaving means that the hydrophobic fibers and polyester fibers form interweaving points in the warp, weft, and thickness directions, thereby constructing a three-dimensional network structure. This structure differs from simple surface coatings or laminated structures, achieving an organic combination of hydrophobic and mechanical properties. The continuous hydrophobic network structure refers to the interconnected network pathways formed by the hydrophobic fibers in the hydrophobic interwoven composite layer 2. This structure ensures that even if some fibers are damaged, the overall hydrophobic properties are maintained.
[0026] A gradient transition zone 3 is disposed between the base fabric layer 1 and the hydrophobic interwoven composite layer 2, forming a gradient change in fiber density and composition. The width of the gradient transition zone 3 is 0.5-1.5 mm.
[0027] The gradient transition zone 3 is a key structure connecting the base fabric layer 1 and the hydrophobic interwoven composite layer 2. Through the gradual change of fiber density and composition, a smooth transition of performance is achieved. The gradient change can include changes in the proportion of fiber types, changes in fiber arrangement density, changes in fiber orientation, etc. These changes can be linear or non-linear. The setting of the gradient transition zone 3 can effectively alleviate interlayer stress concentration, prevent interface peeling, and improve the overall structural stability and service life of the fabric.
[0028] It also includes a low surface energy finishing agent disposed on the surface of the hydrophobic interwoven composite layer, the amount of which is 0.5%-2% of the fabric weight.
