[0026] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of 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.

[0027] The utility model is further described below in conjunction with embodiments.

[0028] Example: Refer to the attached Figure 1-5 As shown in the figure, a cold expansion fabric with autonomous temperature sensing function includes a support layer 100, an adhesive layer 200, an aerogel layer 300, a filling layer 500 and a protective layer 600 arranged in sequence from the outside to the inside; wherein, a plurality of aerogel layers 300 are provided, and are intermittently distributed between the adhesive layer 200 and the middle part of the filling layer 500; it should be noted that in the present application, the support layer 100 is one of cotton cloth, linen cloth or silk, and it can be selected according to actual needs; or a waterproof material is used as the support layer 100.

[0029] It should be noted that in the present application, the aerogel layer 300 is provided, which will shrink when it is cold, and because a through groove 310 is provided in the middle of the aerogel layer 300, when the aerogel layer 300 is cold, it will shrink. Figure 5 As shown in the figure, the aerogel layer 300 will shrink when it is cold, so that the space of the through groove 310 will increase, and the corresponding thickness of the fabric will increase, thereby significantly improving its thermal insulation performance. It should be noted that when the space of the through groove 310 increases, it will be filled with air, which serves as an isolation layer to effectively isolate the external cold air.

[0030] A connecting layer 400 is provided between the middle parts of the two aerogel layers 300, and the connecting layer 400 is also located between the middle parts of the adhesive layer 200 and the filling layer 500. Specifically, when the set aerogel layer 300 expands, the distance between the corresponding support layer 100 and the filling layer 500 will become larger, and the thickness of the fabric will increase. Therefore, in order to ensure the overall stability of the fabric, a connecting layer 400 is provided on the side of the aerogel layer 300. Through the setting of the connecting layer 400, when the aerogel layer 300 shrinks when cold, the stability of each layered structure can be ensured. Furthermore, the adhesive layer 200 is made of thermoplastic polyurethane, and its surface is coated with an adhesive for adhering the support layer 100 to the aerogel layer 300.

[0031] A depression 101 is provided on the support layer 100 at the position of the connecting layer 400, and a plurality of elastic bands 700 are evenly provided on the upper side of the depression 101, and an elastic layer 110 is provided on the support layer 100 at both sides of the depression 101; it should be noted that, by providing the depression 101 on the support layer 100, the so-called depression 101 can be understood as that the support layer 100 is provided relatively thin here, and when the space of the through groove 310 is increased, the support layer 100 will be lifted up, and by providing a relatively thin here, the adhesive layer 200 can be ensured. Adhesion effect, and it should be noted that, in order to ensure that the fabric can be stably restored, in the present application, an elastic layer 110 is also provided on both sides of the recess 101, which can assist the support layer 100 on the fabric to recover when the through groove 310 recovers, and the elastic band 700 connected on both sides of the recess 101 also has the same function. Through the set elastic band 700, when the through groove 310 is restored, the set elastic band 700 can be used to pull the support layer 100 on the fabric, thereby improving the smoothness of the fabric surface after recovery.

[0032] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some of the technical features therein by equivalents. These modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
