[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Reference Figure 1The utility model provides an embodiment: an antibacterial polyester fiber special yarn with good elasticity, comprising a core layer 1, a first elastic fiber 2 is arranged at intervals outside the core layer 1, a filling layer 3 is arranged between the core layer 1 and the first elastic fiber 2, a thermal insulation layer 4 is arranged outside the filling layer 3, a second elastic fiber 5 is arranged outside the thermal insulation layer 4, an antibacterial layer 6 is arranged outside the second elastic fiber 5, and an external protective layer 7 is arranged outside the antibacterial layer 6.

[0023] The core layer 1 is provided with holes 8 inside, and a plurality of nano elastic foam particles 9 are provided between the antibacterial layer 6 and the external protective layer 7. The nano elastic foam particles 9 can be evenly dispersed at the boundary between the antibacterial layer 6 and the external protective layer 7 through the electronic action of the bamboo charcoal fibers in the antibacterial layer 6.

[0024] Four groups of the first elastic fibers 2 are provided, and the first elastic fibers 2 are arranged at intervals with the core layer 1 as the center.

[0025] The core layer 1 is polyester shaped fiber. As the core of the yarn, the core layer 1 provides basic structure and strength. The shaped fiber structure enables the yarn to rebound even when it is displaced in multiple directions. The holes 8 arranged inside not only help to enhance the air permeability of the yarn, but also improve the overall elasticity. Using polyester shaped fiber as the core layer 1 material not only ensures the strength of the yarn, but also provides a good elastic foundation for it.

[0026] The first elastic fibers 2 and the second elastic fibers 5 are highly elastic polyester fibers. Four groups of first elastic fibers 2 are arranged at intervals with the core layer 1 as the center. This design can evenly disperse external forces and enhance the overall elasticity and resilience of the yarn. The second elastic fibers 5 further enhance the elasticity and resilience of the yarn. This dual elastic design enables the yarn to quickly recover to its original shape when subjected to external forces, maintaining its original shape and performance.

[0027] The filling layer 3 is spandex fiber, which has good elasticity and recovery, and can further improve the elasticity of the yarn.

[0028] The thermal insulation layer 4 is a blended fiber of polyester and wool, which not only provides good thermal insulation performance but also enhances the softness and comfort of the yarn.

[0029] The antibacterial layer 6 is a bamboo charcoal fiber and polyester blended fiber, which has excellent antibacterial properties and can effectively inhibit the growth of various bacteria, fungi and viruses.

[0030] The outer protective layer 7 is a waterproof polyester fiber, which provides additional protection for the yarn. This protective layer can resist the invasion of moisture and stains, keep the yarn clean and dry, and at the same time, the waterproof property also allows the yarn to maintain good elasticity and appearance in a humid environment.

[0031] Working principle: This elastic antibacterial polyester fiber special yarn has excellent performance in elasticity, antibacterial performance, warmth retention, breathability, moisture absorption and waterproof performance through the combination of various components.

[0032] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
