Detailed Description of the Embodiments

[0018] The present utility model will be further described below in conjunction with the drawings and specific embodiments.

[0019] First Embodiment

[0020] Combined with Figure 1 and Figure 2 , a detailed description of this embodiment will be given. An antibacterial regenerated polyester fabric involved in this embodiment includes a regenerated polyester fabric layer 1, a thermal insulation fabric layer 2, an antibacterial fabric layer 3, and a skin-friendly fabric layer 4 that are compounded by hot melt adhesive.

[0021] The regenerated polyester fabric layer 1 is woven from regenerated polyester core-spun yarns, which include a first core yarn and a covering yarn. The core yarn is a high-strength polyester filament, and the covering yarn is a regenerated polyester ultra-fine denier DTY yarn with a fineness of 25-75D / 144F-288F. The cross-section of the monofilament in the regenerated polyester ultra-fine denier DTY yarn includes a straight-line fiber body 11 and a number of protrusions 12 symmetrically arranged on both sides of the fiber body 11. The surface of the regenerated polyester fabric layer 1 on the side away from the thermal fabric layer 2 has a fluff layer 5 formed by raising. The cross-section of the monofilament in the regenerated polyester ultra-fine denier DTY yarn is a slender and flat structure, very similar to the appearance of a caterpillar, and has good uprightness, so that the fiber can stand up quickly after bending, thereby restoring the marks on the fluff layer 5 to their original state.

[0022] Furthermore, the thermal insulation fabric layer 2 is interwoven with regenerated hollow polyester core-spun yarn, which includes a second core yarn and a covering staple fiber layer; the covering staple fiber layer is regenerated hollow polyester staple fiber; and the second core yarn is high-strength polyester filament. The hollow polyester staple fiber can provide good thermal insulation.

[0023] Furthermore, the antibacterial fabric layer 3 is woven from golden lian fiber yarns. Golden lian fiber is a regenerated cellulose fiber made by mixing active ingredients extracted from the natural plants honeysuckle, scutellaria, and forsythia with natural wood pulp. This fiber possesses excellent antibacterial and antiviral properties, as well as a natural deodorizing function, while maintaining good moisture absorption.

[0024] Furthermore, the skin-friendly fabric layer 4 is formed by interweaving twisted acetate fiber filaments and cuprammonium fiber filaments.

[0025] Example 2

[0026] Combine Figure 3 , this embodiment is described in detail. The antibacterial recycled polyester fabric involved in this embodiment differs from the first embodiment in that a waterproof and breathable membrane 6 is provided between the recycled polyester fabric layer 1 and the thermal insulation fabric layer 2. The waterproof and breathable membrane 6 used is a PTFE micro-polyester membrane.

[0027] Another difference from Example 1 is that a water repellent is attached to the surface of the regenerated polyester ultrafine denier DTY yarn.

[0028] The preferred specific embodiments of the present utility model have been described in detail above. It should be understood that those of ordinary skill in the art can make many modifications and variations based on the concept of the present utility model without creative efforts. Therefore, all technical solutions that can be obtained by those skilled in the art in the technical field based on the concept of the present utility model through logical analysis, reasoning or limited experiments on the basis of the prior art shall fall within the protection scope determined by the claims.
