They are not only essential at fire rescue sites, but also serve as firefighting tools to protect firefighters from injury. Therefore, firefighter uniforms that are suitable for fire rescue activities are particularly important.

[0003] For example, the authorization announcement number "CN220212135U" is named as a Velcro structure. Although the reflective strip can be sewn and installed through the second base fabric, a prompt can be obtained when used at night, so that the user can use it normally in special environments. At the same time, it can also be pasted on the user's clothing as a reminder, indicating the practicality of the Velcro. However, the existing Velcro structure needs to be used on fire-fighting clothing to tie and fix the fire-fighting clothing. Fire-fighting clothing requires firefighters to wear it frequently in and out of high-temperature and high-risk areas such as fire scenes. In this way, the Velcro structure used for tying and fixing will easily come into contact with burning flames and high temperatures. The hook surface and velvet surface of the Velcro structure are directly exposed to the fire scene. The velvet surface and the hook surface will be burnt when encountering open flames, and thus cannot play the role of fixing and adhering. Therefore, it directly affects the poor flame retardant performance of the Velcro structure. Utility Model Content
