Description

Technical Field

[0001] This application belongs to the field of knitted fabric technology, specifically relating to a polyester fabric with moisture-resistant and antistatic functions. Background Technology

[0002] Polyester fabric, due to its excellent strength, abrasion resistance, ease of care, and low cost, has become one of the core materials in the current textile market. It is widely used in clothing, home textiles, and industrial textiles, especially in winter thermal clothing. According to industry statistics, polyester fiber accounts for more than 70% of global synthetic fiber production, demonstrating its important position in the modern textile industry.

[0003] However, the chemical structure of polyester inherently presents two major drawbacks: firstly, static electricity buildup. Due to its hydrophobicity and high insulation, polyester is highly susceptible to static electricity in dry environments, causing clothing to attract dust, feel uncomfortable against the skin, and even pose safety hazards in certain conditions. Secondly, its moisture-wicking ability is poor. Polyester's standard moisture regain is only 0.4%, far lower than cotton's 8%, resulting in sweat remaining on the skin's surface, causing stuffiness and exacerbating the feeling of cold in low-temperature environments. Therefore, moisture-wicking treatment is particularly important. Existing technologies have proposed various moisture-wicking structures or process designs for hydrophobic synthetic fibers such as polyester and acrylic to improve their wearing comfort.

[0004] Patent application CN202221025619.4 proposes a double-layer composite moisture-wicking fabric. This fabric utilizes an outer layer of acrylic-viscose blended yarn to promote moisture evaporation, an inner layer of cotton yarn to absorb sweat, and a grooved structure in the middle layer of Kanglun antibacterial moisture-wicking filaments to achieve one-way moisture wicking. This solution can improve wearing comfort through the synergistic effect between multiple fiber components and structures. However, significant limitations exist in practical use: moisture wicking relies on capillary action, and the grooved structure is prone to deformation and blockage after repeated washing or friction, leading to a decrease in moisture-wicking performance; cotton fibers tend to swell and clump after absorbing moisture, affecting breathability and warmth, thus reducing wearing comfort; simultaneously, the processing of antibacterial filaments is complex and costly, limiting its large-scale production. Furthermore, this solution does not address the problem of static electricity buildup in the fabric, which may still cause discomfort such as dust accumulation and electric shock during wear. Therefore, how to integrate long-lasting moisture wicking and antistatic functions while retaining the lightweight and warmth advantages of polyester remains a core challenge that urgently needs to be overcome in the current research and development of polyester fabrics. Utility Model Content

[0005] To solve the above-mentioned technical problems, this application provides a polyester fabric with moisture-proof and antistatic functions, which is achieved through the following technical solution:

[0006] The moisture-resistant and antistatic polyester fabric includes a ground yarn structure and a face yarn structure, and a moisture-wicking structure for transferring moisture from the ground yarn structure to the outer surface of the face yarn structure. The moisture-wicking structure includes an evaporation zone on the outer surface of the face yarn structure, and the evaporation zone has evaporation zone yarns. The outer surface of the face yarn structure has face yarns, and the face yarns and the evaporation zone yarns interweave to form a moisture-wicking cluster, and the moisture-wicking cluster has a breathable space inside.

[0007] Preferably, along the direction from the ground yarn to the face yarn, the moisture-wicking cluster includes a capillary moisture-wicking area arranged in a gathered shape, and an interwoven moisture-wicking area formed at the end of the capillary moisture-wicking area and arranged in an expanded shape.

[0008] Preferably, air channels are formed between the moisture-wicking clusters, and the air channels include bottom channels distributed between the interwoven moisture-wicking zones and top channels distributed between the capillary moisture-wicking zones.

[0009] Preferably, the outer surface of the yarn structure has a windproof tuft formed by the interlacing of the yarn fibers; along the direction from the ground yarn structure to the yarn structure, the windproof tuft includes a gathering area that is arranged in a gathered shape, and a windproof area formed at the end of the gathering area that is in an expanded shape.

[0010] Preferably, the windproof zones are connected to each other, and the windproof zones are connected to the moisture-dissipating zones of the moisture-guiding clusters; and the collection zones are connected to the bottom flow channels and the top flow channels by forming internal flow channels.

[0011] Preferably, the yarn structure includes a tufted loop, and the moisture-wicking structure is connected to the tufted loop to form a moisture-wicking cluster.

[0012] Preferably, the moisture-wicking structure includes a support area distributed between the ground yarn structure and the face yarn structure, wherein the moisture-wicking structure in the support area forms a heat-insulating cavity with the ground yarn structure and the face yarn structure.

[0013] Preferably, the yarn structure uses a composite yarn with filaments as the core layer and stub filaments as the covering layer.

[0014] Compared with the prior art, this application has the following beneficial effects:

[0015] This application incorporates yarn fibers and evaporation zone fibers on the outer surface of the yarn structure, interweaving them to form a moisture-wicking cluster structure. On one hand, moisture from the moisture-wicking structure can be transferred to the relatively dry surface of the yarn fibers via capillary action, creating a larger moisture-dissipating area and improving evaporation efficiency. On the other hand, the moisture-wicking cluster, constructed by the yarn fibers and evaporation zone fibers, creates a breathable space, further enhancing air circulation and significantly accelerating the evaporation rate of moisture.

[0016] This application employs a unique structural design for the moisture-wicking clusters. The capillary moisture-wicking zone efficiently guides sweat absorbed by the moisture-wicking tissue to the outer layer of the fabric via capillary action. Meanwhile, the interwoven moisture-wicking zone at the ends has a looser structure, providing a larger specific surface area and breathable space, which facilitates rapid evaporation and diffusion of moisture. Furthermore, and more importantly, the expanded interwoven moisture-wicking zone not only possesses a certain degree of windproof performance, effectively reducing heat loss caused by cold air penetration, but also promotes moisture evaporation through its windproof properties, achieving a dual function of windproofing and moisture resistance.

[0017] This application enhances airflow and improves drying efficiency in the end area by setting up top and bottom flow channels. Moisture at the end of the capillary moisture-conducting zone undergoes initial drying under the action of the top flow channel, while moisture in the interlacing moisture-dissipating zone undergoes secondary efficient evaporation treatment, thus forming a multi-stage drying mechanism with progressive steps and clear division of labor.

[0018] This application effectively enhances the overall windproof performance of the fabric by introducing windproof yarn clusters. At the same time, by connecting the windproof zone with the interwoven moisture-wicking zone in the moisture-wicking cluster, the moisture migrating from the inner layer can be further expanded to a larger area of ​​the fiber surface after entering the interwoven moisture-wicking zone, and achieve faster moisture evaporation with the help of the windproof zone.

[0019] This application forms a moisture-wicking cluster by setting a tufted coil in the yarn structure and connecting the moisture-wicking structure to the tufted coil. This structure can use the abundant yarn of the tufted coil to disperse moisture to a larger fiber surface area, significantly increasing the effective surface area for evaporation and enhancing the directional transport of moisture from the ground yarn structure to the face yarn structure.

[0020] This application utilizes a thermal insulation cavity structure formed by the enclosing of the moisture-wicking fabric, the ground yarn, and the face yarn. This thermal insulation cavity can accommodate air, effectively improving the overall thermal insulation performance of the fabric. Attached Figure Description

Detailed Implementation

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. Those skilled in the art will be able to implement the present invention based on these descriptions. Furthermore, the embodiments of the present invention described below are generally only a part of the embodiments of the present invention, and not all of the embodiments. Therefore, all other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention.

[0028] Example 1

[0029] This embodiment discloses a moisture-resistant and antistatic polyester fabric, including: a ground yarn structure 100 and a face yarn structure 200 respectively, and a moisture-wicking structure 300 for transferring moisture on the ground yarn structure 100 to the outer surface of the face yarn structure 200.

[0030] Please see the appendix Figure 2 and 3 In this embodiment, the ground yarn structure 100 is made of 75D heterogeneous hollow polyester filament plain knitting, and the face yarn structure 200 is made of 75D filament (core layer) / 50D staple fiber (outer layer) composite yarn. While it is made of plain knitting, tuck loops 220 are set in some positions. Tuck loops 220 and plain knitting are existing technologies and will not be described in detail in this part.

[0031] Moisture-wicking structures 300 are interleaved on the ground yarn structure 100 and the face yarn structure 200 to connect them. They include an evaporation zone on the outer surface of the face yarn structure 200, a moisture-absorbing zone on the inner surface of the ground yarn structure 100, and a support zone between the ground yarn structure 100 and the face yarn structure 200. The moisture-wicking structures 300 in the support zone form an insulation cavity 600 with the ground yarn structure 100 and the face yarn structure 200. The evaporation zone is formed with evaporation zone yarns 310; the looped coils 22 on the outer surface of the face yarn structure 200 form face yarns 210, which interweave with the evaporation zone yarns 310 to form a moisture-wicking cluster 400. Along the direction from the ground yarn structure 100 to the face yarn structure 200, the moisture-wicking cluster 400 includes a capillary moisture-wicking zone 420 arranged in a gathered shape, and an interwoven moisture-dissipating zone 430 formed at the end of the capillary moisture-wicking zone 420 and exhibiting an expanded shape. The moisture-wicking clusters 400 have an air-permeable space 410 inside. In addition, air channels 440 are formed between the moisture-wicking clusters 400, and the air channels 440 include bottom channels 441 distributed between the interlaced moisture-dissipating zones 430 and top channels 442 distributed between the capillary moisture-wicking zones 420.

[0032] In this embodiment, the moisture-wicking and antistatic polyester fabric, during use, first absorbs sweat or moisture from the skin surface through the moisture-absorbing zone on one side of the ground yarn weave 100. Subsequently, under the action of capillary effect, moisture is directionally transported from the inside to the outside along the moisture-wicking weave 300, passing sequentially through the support zone, the capillary moisture-wicking zone 420, and finally reaching the interwoven moisture-dissipating zone 430. The support zone not only provides structural support but also lays the foundation for the formation of the insulation cavity, helping to improve the fabric's warmth retention performance. The capillary moisture-wicking zone 420, through its converging structure, efficiently guides moisture, ensuring stable migration of moisture to the outer layer. The interwoven moisture-dissipating zone 430, due to its more open structure, has a larger specific surface area and breathable space 410, which facilitates rapid evaporation and diffusion of moisture. Furthermore, the airflow channels 440 located on the outer layer and the breathable space 410 inside the moisture-wicking cluster work synergistically to enhance the overall airflow capacity of the fabric, further accelerating the evaporation rate of moisture on the fabric surface. This achieves a complete moisture removal process from moisture absorption and conduction to evaporation and drying, while also ensuring dryness and warmth during wear, significantly improving the overall comfort and functionality of polyester fabrics in sportswear, winter thermal clothing, and other scenarios.

[0034] The difference between this embodiment and Embodiment 1 is that, in this embodiment, the outer surface of the yarn structure 200 is formed with a yarn windproof cluster 500 formed by the interlacing of the yarn strands 210; along the direction from the ground yarn structure 100 to the yarn structure 200, the yarn windproof cluster 500 includes a gathering area 510 arranged in a gathered shape, and a windproof area 520 formed at the end of the gathering area 510 and arranged in an expanded shape. The windproof areas 520 are connected to each other, and the windproof areas 520 are connected to the interlaced moisture-dissipating areas 430 of the moisture-wicking cluster 400; and an internal flow channel 530 is formed between the gathering areas 510, communicating with the bottom flow channel 441 and the top flow channel 442.

The preparation method includes: preparing a ground yarn structure 100 and a face yarn structure 200 using a plain knitting process; interlacing a moisture-wicking structure 300 on the loops of the ground yarn structure 100 and the face yarn structure 200 to connect them and form the basic skeleton of the moisture-resistant and antistatic polyester fabric; performing a napping process on one side of the outer surface of the fabric to obtain a fluffy pile structure; and performing a tumbling process on the fabric using a tumbling machine to obtain the moisture-resistant and antistatic polyester fabric.
