[0015] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0016] A type of warm composite knitted fabric, such as Figure 1 As shown, the device includes an insulation layer 1 and an outer covering layer 2. The outer covering layer 2 covers both sides of the insulation layer 1. The insulation layer 1 has two layers, and multiple elastic strips 3 are wrapped between the two insulation layers 1. The elastic strips 3 are arranged parallel to each other, and the elastic strips 3 cause the insulation layer 1 to form multiple protrusions 4. The outer covering layer 2 forms a cover for the insulation layer 1, thereby protecting the insulation layer 1 and reducing the airflow of the insulation layer 1 to the outside, thus creating an air retention effect. The setting of the elastic strips 3 increases the air retention space of the insulation layer 1. The elastic strips 3 are set in a folded shape, and the elastic strips 3 form abutment with the insulation layer 1 through their outer surface. The folded shape of the elastic strips 3 can increase the space for the protrusions 4 of the insulation layer 1, thereby providing a supporting effect for the knitted fabric when it is under pressure, and reducing the contact area between the knitted fabric and other objects.

[0017] Adhesive is provided on the side of the insulation layers 1 that are close to each other, and the insulation layers 1 are bonded together to form an adhesive fixation for the elastic strip 3. The elastic strip 3 is fixed to each other in the insulation layers 1 by adhesive, thereby fixing the position of the elastic strip 3 and preventing the elastic strip 3 from shifting in the insulation layers 1. Yarn is provided between the insulation layers 1 and the outer covering layer 2, and the yarn forms a stitch between them. The stitch between the yarn and the insulation layers 1 and the outer covering layer 2 makes the insulation layers 1 and the outer covering layer 2 mutually fixed.

[0018] The insulating layer 1 is made of wool. Wool fibers have many tiny scales and crimps in their structure, which can store a large amount of air, thus providing a warming effect. The elastic strip 3 is made of needle-punched material. Needle-punched material can be made of polyester staple fiber or hollow fiber. The felt-like structure produced by it is elastic. The outer covering layer 2 is made of polyester fiber material. Polyester fabric has the advantages of smooth surface, high strength, and wear resistance.

[0019] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0020] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
