Description

Technical Field

[0001] This utility model relates to a moisture-wicking, quick-drying, environmentally friendly polyester fabric, belonging to the technical field of polyester fabrics. Background Technology

[0002] With increasing global environmental awareness, the demand for eco-friendly textiles is growing. Polyester is a synthetic fiber made from organic diacids and diols through chemical polymerization; it belongs to the category of polymer compounds. As the most widely used and consumed synthetic fiber, it primarily utilizes non-renewable petroleum resources. With the rapid development of the global PET industry, related waste is also increasing. To address PET waste, recycling and reusing PET waste has become an important environmental protection measure, which not only helps control environmental pollution but also promotes sustainable development. Polyester fabrics tend to stick to the skin after absorbing moisture, causing discomfort to the wearer. Therefore, how to utilize recycled polyester fibers to prepare an eco-friendly polyester fabric with moisture-wicking and quick-drying properties has become a problem to be solved. Utility Model Content

[0003] The purpose of this invention is to provide a moisture-wicking, quick-drying, environmentally friendly polyester fabric that uses environmentally friendly recycled polyester filaments. While being environmentally friendly, it also has the effect of wicking away moisture and drying quickly.

[0004] To solve the above-mentioned technical problems, the purpose of this utility model is achieved as follows:

[0005] This utility model relates to a moisture-wicking and quick-drying environmentally friendly polyester fabric, which is woven from warp and weft yarns in a satin weave, and includes a warp surface and a weft surface.

[0006] The warp yarn comprises shaped cross-section recycled polyester filaments, wherein the shaped cross-section of the monofilaments in the shaped cross-section recycled polyester filaments is 60%-70%; the weft yarn comprises hydrophilic modified recycled polyester filaments.

[0007] Based on the above scheme and as a preferred embodiment of the above scheme: the cross-section of the monofilament in the irregular cross-section recycled polyester filament is trilobal or cross-shaped.

[0008] Based on the above scheme and as a preferred embodiment of the above scheme: the irregular cross-section recycled polyester filament and the hydrophilic modified recycled polyester filament have the same twist direction.

[0009] Based on the above scheme and as a preferred embodiment of the above scheme: the warp yarn further includes bio-based polyamide cooling fiber yarn; the bio-based polyamide cooling fiber yarn and the irregular cross-section recycled polyester filament are arranged in the order of m:m, where m is a positive integer multiple of the minimum number of warp yarn cycles.

[0010] Based on the above scheme and as a preferred embodiment of the above scheme: the weft yarn also includes fully dull polyester filament; the fully dull polyester filament and the hydrophilic modified recycled polyester filament are arranged in an order of n:n, where n is a positive integer multiple of the minimum number of weft yarn cycles.

[0011] The beneficial effects of this utility model are as follows: The moisture-wicking and quick-drying environmentally friendly polyester fabric involved in this utility model uses recycled polyester filaments with highly irregular cross-sections for the warp yarns, which have excellent moisture-wicking properties and can reduce the contact area with the skin. The weft yarns use hydrophilic modified recycled polyester filaments, which can absorb sweat to the weft side. Furthermore, because polyester fibers have poor water absorption, the absorbed sweat can evaporate, thus enabling the fabric to dry quickly. Attached Figure Description

[0015] The markings in the diagram are explained as follows: 1-warp side; 2-weft side; 10-warp yarn; 20-weft yarn. Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0017] Example 1

[0018] Combination Figure 1 and Figure 2 This embodiment will be described in detail below. The moisture-wicking, quick-drying, environmentally friendly polyester fabric involved in this embodiment is woven from warp yarns 10 and weft yarns 20 in a satin weave, including a warp face 1 and a weft face 2. Due to the characteristics of the satin weave, one side is the warp face 1 representing the warp floats, and the other side is the weft face 2 representing the weft floats. This allows the warp face 1 of the fabric to exhibit the characteristics of warp yarns 10 on one side, and the weft face 2 on the other side to exhibit the characteristics of weft yarns 20.

[0019] The warp yarns comprise shaped cross-section recycled polyester filaments, wherein the irregularity of the cross-section of each filament in the shaped cross-section recycled polyester filaments is 60%-70%. Shaped cross-section recycled polyester filaments have good moisture-wicking properties and can reduce the contact between the fabric and human skin during use, thus preventing sweat from adhering to the skin after it has accumulated on its surface.

[0020] Furthermore, the cross-section of the monofilament in the irregularly shaped recycled polyester filament is either trilobal or cross-shaped. In this embodiment, a trilobal shape is used, specifically with a fineness of 38.9 dtex / 48F.

[0021] The weft yarn comprises hydrophilic modified recycled polyester filaments. The recycled polyester fibers were pretreated by washing them with ethanol and deionized water followed by ultrasonic treatment for 5 minutes each, and then dried in an oven at 60°C. The recycled polyester fibers were then treated for a certain period using a DBD-50 atmospheric low-temperature plasma device from Nanjing Suman Plasma Technology Co., Ltd.

[0022] The stability of the hydrophilic modification effect of plasma-modified recycled polyester fibers was determined by measuring the water contact angle. The untreated recycled polyester fibers had a water contact angle of 135.9°, exhibiting hydrophobicity. After plasma treatment, the surface of the recycled polyester fibers became superhydrophilic, with a contact angle of 0°. This indicates that atmospheric pressure air plasma treatment can improve the hydrophilicity of recycled polyester fibers. This is because the etching effect of plasma creates numerous pits on the surface of the recycled polyester fiber monofilaments, thereby increasing the adsorption of water droplets. Another reason is that plasma introduces a large number of oxygen-containing functional groups onto the surface of the recycled polyester fibers, thus enhancing hydrophilicity.

[0023] Furthermore, the irregularly shaped cross-section recycled polyester filament and the hydrophilic modified recycled polyester filament have the same twist direction. When the warp and weft yarns have the same twist direction, they are entangled and do not easily slip.

[0024] Furthermore, in this embodiment, a 5-ribbed satin weave is selected.

[0025] Example 2

[0026] Furthermore, the warp yarns also include bio-based polyamide cooling fiber yarns; the bio-based polyamide cooling fiber yarns and profiled recycled polyester filaments are arranged in an m:m ratio, where m is a positive integer multiple of the minimum warp yarn repeat number. The weft yarns also include fully dull polyester filaments; the fully dull polyester filaments and hydrophilic modified recycled polyester filaments are arranged in an n:n ratio, where n is a positive integer multiple of the minimum weft yarn repeat number. In this embodiment, an 8-end satin weave is selected, specifically, in this embodiment, both m and n are 8.

[0027] 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.
