Description

Technical Field

[0001] This utility model relates to the field of polyester fabric technology, specifically to an antibacterial polyester fabric. Background Technology

[0002] Polyester fabric is a common synthetic fiber fabric, also known as polyester fiber. This fabric is favored for its strength, durability, elasticity, resistance to deformation, and corrosion resistance. Polyester fabric is widely used in the sports field, mainly due to its excellent physical and chemical properties.

[0003] When polyester fabric is used in sportswear, the sweat and moisture released during exercise can cause the fabric to remain damp and hot for a long time, increasing the chance of bacteria growth inside. In addition, polyester fabric is a water-wicking fabric, and sweat tends to accumulate on the skin surface when worn during exercise in summer. Furthermore, after exercise, the wearer loses heat quickly through the fabric, making them more susceptible to catching a cold if there is a large temperature difference between the outdoor environment and the body surface. Utility Model Content

[0004] The purpose of this invention is to provide an antibacterial polyester fabric to solve the problems mentioned in the background art, such as the fact that the sweat and moisture expelled during exercise can cause the inside of the fabric to remain damp and hot for a long time, which increases the chance of bacteria growing inside the fabric. In addition, polyester fabric is a water-wicking fabric, and sweat tends to accumulate on the skin surface when worn for exercise in summer. Also, after exercise, the wearer loses heat to the outside through the fabric at a relatively fast rate, which can easily lead to colds when there is a large temperature difference between the outdoor temperature and the body surface temperature.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an antibacterial polyester fabric, comprising a polyester layer, a core layer between two polyester layers, the polyester layers being sewn together with the core layer by sewing thread, the outer polyester layer having a first blended yarn internally, the second blended yarn being composed of a protective yarn and a reinforcing yarn, the protective yarn and the reinforcing yarn being twisted and woven together, the inner polyester layer having a second blended yarn internally, the second blended yarn being composed of a cooling yarn and an elasticizing yarn, the cooling yarn and the elasticizing yarn being twisted and woven together.

[0006] Preferably, the surface of the sandwich layer is uniformly provided with a plurality of air vents.

[0007] Compared with the prior art, the beneficial effects of this utility model are as follows: This antibacterial polyester fabric has the following advantages over traditional technology:

[0008] Through the combination of polyester layers, first blended yarns, second blended yarns, a core layer, and sewing threads, the fabric is processed into sportswear for wear. The inner polyester layer, with the second blended yarn, faces inward and contacts the wearer's skin, while the inner polyester layer, with the first blended yarn, faces outward and away from the wearer's skin. The polyester layer is spun from modified polyester fibers, possessing excellent moisture-wicking and antibacterial properties. Sweat and moisture generated during exercise can be quickly wicked away, improving the damp and stuffy environment inside the fabric. Combined with the antibacterial effect, it can significantly reduce the chance of bacteria growing inside the fabric. In addition, the cooling yarn in the second blended yarn has excellent thermal conductivity, and the skin-friendly yarn can enhance the comfort of wearing it. The core layer can store some of the heat lost by the skin during exercise, slowing down the rate at which the wearer's heat is lost to the outside through the fabric after exercise, making it less likely to catch a cold when there is a large temperature difference between the outdoor temperature and the body surface temperature.

[0009] Through the combination of polyester layer, first blended thread, second blended thread, core layer and sewing thread, the first blended thread blended towards the inside of the outer polyester layer can improve the fabric's resistance to ultraviolet rays, reduce the impact of ultraviolet rays on the inner skin during outdoor sports, and also improve the abrasion resistance of the polyester layer, thus improving the fabric's durability.

[0015] 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.

[0016] Please see Figure 1-3This utility model provides a technical solution: an antibacterial polyester fabric, including a polyester layer 1, which is woven from modified polyester fiber yarns. The modified polyester fiber yarns are produced by introducing substances capable of inhibiting bacterial growth into the fiber surface and interior using chemical or physical methods, thereby inhibiting bacterial reproduction on the fiber and preventing the production of volatile odors. Specifically, the antibacterial and deodorizing functions of the fabric are achieved through a blending spinning method. Antibacterial agents mainly fall into two categories: one is inorganic antibacterial agents, primarily metal oxides and silver series; the other is organic antibacterial agents, primarily organosilicon, quaternary ammonium salts, etc. The antibacterial material is added during the polymerization process using a blending spinning method to ensure uniform distribution. Dispersed within the chips, the fibers are spun into fibers with a long-lasting antibacterial effect. The spinning process requires a spinneret with a cross-shaped structure, resulting in grooves on the surface of the modified polyester fiber filaments to increase surface area and facilitate the rapid outward removal of sweat and moisture. A core layer 4 is located between the two polyester layers 1. This core layer 4 is a phase-change temperature-regulating fiber fabric, made by coating the fiber surface with microcapsules containing phase-change materials using high-tech methods. At normal body temperature, this material exists in both solid and liquid states. When clothing is made from this fiber, upon entering a higher temperature environment from a normal temperature environment, the phase-change material changes from solid to liquid to absorb heat. In low-temperature environments, the phase change material changes from liquid to solid, releasing heat and thus slowing down changes in body surface temperature. The polyester layer 1 is sewn to the core layer 4 by sewing thread 5. Sewing thread 5 is an anti-static thread, made from a mixture of conductive carbon fiber and polyester filament, possessing high tensile strength. It eliminates static electricity on the fabric through the corona discharge and leakage effect of the conductive fibers. The outer polyester layer 1 has a first blended thread 2 internally blended. The second blended thread 2 consists of a protective thread 21 and a reinforcing thread 22, which are twisted and woven together. The protective thread 21 is made of pearl fiber, where nano-grade pearl powder is added to the viscose fiber during spinning, making the fiber both internally and externally... The fabric is uniformly distributed with nano-pearl particles, which have the function of resisting ultraviolet rays. The reinforcing thread 22 is an aramid fiber thread with ultra-high strength. The inner polyester layer 1 is internally blended with a second blended thread 3, which is composed of a cooling thread 31 and an enhancing thread 32. The cooling thread 31 and the enhancing thread 32 are twisted and woven together. The cooling thread 31 is a master cooling fiber thread with excellent thermal conductivity. The enhancing thread 32 is a real silk thread that is very skin-friendly and has the lowest coefficient of friction against human skin. This blend of threads can improve the skin-fitting experience of the fabric to a certain extent after it is finished. The surface of the sandwich layer 4 is evenly provided with multiple breathable holes 6, which can improve the breathability of the sandwich layer 4.

[0017] The processing personnel first lay the sandwich layer 4 between the two polyester layers 1, and then sew the polyester layers 1 and the sandwich layer 4 together using sewing thread 5. This allows the fabric to be processed into sportswear for wear. The polyester layer 1 with the second blended yarn 3 inside faces inward and contacts the wearer's skin, while the polyester layer 1 with the first blended yarn 2 inside faces outward and away from the wearer's skin. The polyester layer 1 is made of modified polyester fiber, which has excellent moisture-wicking and antibacterial effects. The sweat and moisture generated by the wearer during exercise can be quickly wicked away to the outside, improving the damp and stuffy environment inside the fabric. Combined with the antibacterial effect, it can significantly reduce the chance of bacteria growing inside the fabric. In addition, the cooling yarn 31 in the second blended yarn 3 has excellent heat conduction effect, and the conditioning yarn 32 is very skin-friendly, which can improve the comfort of wearing. The sandwich layer 4 can store some of the heat lost by the skin during exercise. After exercise, the rate of heat loss from the wearer to the outside through the fabric is slowed down, making it less likely to catch a cold when there is a large difference between the outdoor temperature and the body temperature.
