The invention discloses a fluorescent inflaming-retarding multifunctional double-layer fabric. The surface layer of the fabric is woven from inflaming-retarding yarn capable of being dyed with fluorescence color, and the inner layer of the fabric is woven from non-melting inflaming-retarding yarn incapable of being dyed with fluorescence color. The warps of the inner layer are lifted to be interwoven with the wefts of the surface layer to form a binding texture so that the two layers can be connected. The fabric is prepared in the way that the warps of the inner layer are lifted to be interwoven with the wefts of the surface layer to form the binding texture so that the two layers can be connected, and then dyeing treatment is conducted to generate the fluorescent inflaming-retarding multifunctional double-layer fabric. Specifically, the two layers of the fabric are connected in the way that when surface wefts are put in for surface layer weaving, all inner warps must sink to the space below a shed and can not be interwoven with surface wefts; when inner wefts are put in for inner layer weaving, all surface warps must be lifted and can not be interwoven with inner wefts. The double-layer fabric can have different spaces and can be used for making protection garments in a plurality of fields.
