Anti-skid flame-retardant skin-friendly helmet belt and preparation method thereof

The invention provides an anti-skid flame-retardant skin-friendly helmet belt and a preparation method thereof, and relates to the technical field of textiles. The helmet belt is provided with a first surface and a second surface, the first surface is of a plain structure, and the second surface is of a concave-convex structure. The first surface is used for making contact with a human body, and the second surface is used for making contact with a buckle of a helmet. The surface, making contact with the human body, of the helmet belt is of a plain structure, the helmet belt better fits the face, and the comfort degree is better. The surface, buckled with the buckle, of the helmet belt is of a concave-convex structure, so that the buckle can be attached to the helmet belt more tightly, the anti-sliding effect is achieved, and the safety is effectively improved. In addition, the helmet belt is prepared from the yarn obtained by blending the flame-retardant viscose fibers, the flame-retardant polyamide fibers an
