Description

Technical Field

[0001] The utility model belongs to the technical field of polyester fabrics, in particular to a one-way moisture-conducting polyester fabric. Background Art

[0002] The design concept of unidirectional moisture-conducting fabrics is based on the differential moisture absorption properties of the two sides of the fabric. The inner side, which is closest to the skin, is significantly hydrophobic, while the outer side is highly hydrophilic. This unique design allows moisture to transfer unidirectionally from the inside to the outside, thereby maintaining a continuously dry inner side of the fabric. Currently available unidirectional moisture-conducting fabrics are generally manufactured using a multi-layer composite technology. This technology creates a significant difference in water absorption by laminating hydrophilic and hydrophobic fabric layers, thereby achieving unidirectional moisture-conducting properties.

[0003] However, it is worth noting that the existing one-way moisture-conducting fabrics only rely on the hydrophobic properties of the inner fabric in terms of hydrophobic performance, and sweat cannot be absorbed quickly. There is still room for improvement in the sweat absorption speed. Utility Model Content

[0005] The purpose of the utility model is to overcome the above-mentioned shortcomings and provide a unidirectional moisture-conducting polyester fabric.

The inner layer includes an inner plane structure and a convex structure, while the outer layer includes an outer plane structure and a concave structure. The convex structure forms a convex shape from the inside to the outside, which effectively avoids direct contact with the skin surface, thereby significantly improving the air circulation performance of the fabric.

[0018] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0019] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are also within the scope of protection of the present invention.

[0020] According to an embodiment of the present utility model

[0021] Reference Figure 1 The present embodiment discloses a unidirectional moisture-conducting polyester fabric, including a fabric body. The fabric body is a double-layer structure, including an inner layer 1 and an outer layer 2. The mesh of the inner layer 1 is larger than the mesh of the outer layer 2. The larger the mesh of the inner layer 1, the smaller the mesh of the outer layer 2. The sweat is accelerated from the inside to the outside and evaporates and dries quickly in the outer layer. The inner layer 1 includes an inner plane structure 11 and a convex structure 12. The outer layer 2 includes an outer plane structure 21 and a concave structure 22. The inner plane structure 11 includes hydrophobic fibers 3, and the convex structure 12 includes hydrophobic fibers 3. The hydrophilic fiber 4 is twisted on one side of the hydrophobic fiber 3, the outer plane structure 21 and the concave structure 22 both include the hydrophilic fiber 4, the hydrophobic fiber 3 includes the hydrophobic polyester fiber, the hydrophilic fiber 4 includes the hydrophilic polyester fiber, and the polyester yarn is treated with a specific process and subjected to water-repellent finishing and hydrophilic finishing respectively, thereby preparing polyester fibers with significant hydrophobicity and polyester fibers with excellent hydrophilic properties. The specifications of the hydrophobic polyester fiber are 50D / 24F, and the specifications of the hydrophilic polyester fiber are 50D / 216F.

[0022] The convex structure 12 forms a raised shape from the inside out, effectively avoiding direct contact with the skin's surface, thereby significantly improving the fabric's air circulation performance. The concave structure 22 closely cooperates with the convex structure 12, increasing the contact area between the inner layer 1 and the outer layer 2, and can quickly absorb sweat into the outer layer 2 for moisture conduction. Convex structure 12 is composed of hydrophobic polyester fibers and hydrophilic polyester fibers twisted on one side of the hydrophobic polyester fibers. Sweat is first conducted through the hydrophobic polyester fibers on the inner planar structure 11 into the convex structure 12. As the hydrophobic polyester fibers in the convex structure 12 disperse sweat, they are simultaneously absorbed by the hydrophilic polyester fibers and then quickly transferred to the hydrophilic polyester fibers of the outer layer 2.

[0023] Reference Figure 3 In this embodiment, the hydrophobic fiber 3 and the hydrophilic fiber 4 adopt an S-twist structure. The S-twist can generate prestress between the fibers, increase the cohesion between the fibers, and thus improve the strength of the yarn. The S-twist structure makes the distribution between the hydrophilic polyester fiber and the hydrophobic polyester fiber more even, which can further increase the speed of sweat absorption.

[0024] Reference Figure 2In this embodiment, the fabric body is weft-knitted using a double-sided circular knitting machine. The fabric body has a minimum repeating structure of 12 loops, and the needle arrangement includes upper and lower disc needle rows AB, where A represents high-heel needles and B represents low-heel needles. The high-heel needles and high-heel needles in loops 1 and 4 are loop-forming, while the low-heel needles in the upper and lower discs are floats. The low-heel needles in loops 2, 3, 5, and 6 are loop-forming, while the high-heel needles in the lower disc, high-heel needles in the lower disc, and low-heel needles in the upper disc are loop-forming. The low-heel needles in loops 7 and 10 are loop-forming, while the high-heel needles in the upper disc and high-heel needles in the lower disc are loops. The high-heel needles in the upper disc and high-heel needles in the lower disc are floats. The high-heel needles in the lower disc, high-heel needles in the upper disc, and low-heel needles in the lower disc are loops. The entire one-way moisture-conducting polyester fabric wicks moisture quickly and effectively.

[0025] The unidirectional moisture-conducting polyester fabric in this embodiment was tested for moisture absorption, quick-drying and moisture absorption and perspiration wicking before and after washing. The test results are shown in Tables 1 and 2:

Specifically, this fabric exhibits excellent water absorption rate, achieving rapid water absorption. Simultaneously, its high unidirectional transfer index effectively promotes directional moisture conduction. Furthermore, this fabric exhibits a rapid diffusion rate and a wide diffusion range, ensuring rapid and even distribution of moisture. In summary, the unidirectional moisture-conducting polyester fabric used in this embodiment demonstrates significant improvements in moisture absorption, moisture conduction, and diffusion properties, with excellent moisture absorption, quick-drying, and moisture wicking properties.
