The invention discloses a production process of a finely woven velvet fabric with antibacterial and flame-retardant functions. The weight ratio of cotton fiber to terylene fiber to bamboo charcoal fiber to aramid fiber is 65:10:12:13. A manufacturing method of the finely woven velvet fabric comprises the following steps of shaping the fabric by using the step (1), the step (2) and the step 3 as the basis through a warp knitting machine; performing dyeing, dewatering width opening, galling, luster finishing, wool cutting and curling processing on the shaped fabric; coating glue onto the fabricsurface layer; bonding nylon velvet onto the glue layer. The cotton fiber is used as yarn A; terylene fiber is used as a yarn B; the bamboo charcoal fiber is used as a yarn C; the aramid fiber is usedas a yarn D; the yarns A, B, C and D are used as raw materials to obtain the fabric in a warp knitting mode; then, epoxy resin is coated onto the surface layer of the fabric to be used as adhesives;a layer of nylon fiber is bonded to be used as the velvet, so that the surface layer of the whole fabric is flat; the antibacterial and flame-retardant effects are achieved; meanwhile, the fabric dimension structure is stable; the long-time use is convenient.
