Detailed Description

Embodiments of the present utility model will be described in detail below with reference to the accompanying drawings.

In the description of the present utility model, it should be understood that the terms "center," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," and the like indicate orientations or positional relationships based on the orientation or positional relationships shown in the drawings, merely to facilitate describing the present utility model and simplify the description, and do not indicate or imply that the devices or elements referred to must have a specific orientation, be configured and operated in a specific orientation, and thus should not be construed as limiting the present utility model.

The terms "first," "second," and the like, are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include one or more such feature. In the description of the present utility model, unless otherwise indicated, the meaning of "a plurality" is two or more.

In the description of the present utility model, it should be noted that, unless explicitly specified and limited otherwise, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be either fixedly connected, detachably connected, or integrally connected, for example; can be directly connected or indirectly connected through an intermediate medium, and can be communication between two elements. The specific meaning of the above terms in the present utility model will be understood in specific cases by those of ordinary skill in the art.

The armband comprises a five-layer composite structure, and sequentially comprises the following components from outside to inside: the surface layer 1 is a flame-retardant silk jacquard woven sheet; an adhesive layer 2; is a flame-retardant high-melting film; the middle layer 3 is flame-retardant lining cloth; an adhesive layer 4; is a flame-retardant high-melting film; the bottom layer 5 is a hook surface of the flame-retardant fastening tape; the peripheral side of the armband is formed by wrapping and stitching the flame-retardant stretch yarn 6.
