The invention discloses a hollowed-out mini-jacquard weft-knitting elastic silk fabric. The elastic silk fabric forms circulation by mutually connecting single face plain stitch and jacquard stitch, wherein a plain area is woven by coarse count spun silk and spandex; the jacquard part is woven by fine-denier mulberry silk and is of a hollowed-out structure of transverse circulation arrangement and longitudinal dislocation arrangement, and mulberry silk connected with the transversely arranged hollowed-out jacquard part is hidden in the reverse side of the spun silk plain stitch structure without exposing the bottom; circulation is achieved every 14 weaving ways, the ways from the first to the sixth and the ways from the eighth to the thirteenth each adopt the spun silk and spandex, and the seventh way and the fourteenth way adopt the mulberry silk; three knitting needles are arranged in the mode that circulation is achieved every 8 needles, the knitting needles from the first to the third of the ways from the first to the sixth and the ways from the eighth to the thirteenth are woven into a circle to form a single face plain stitch area, the knitting needles from the first to the third of the seventh way are woven into circles, tuck and floating threads to form the hollowed-out jacquard part, and the knitting needles from the first to the third of the fourteenth way are woven into circles, tuck and floating threads to form the hollowed-out jacquard part. The hollowed-out mini-jacquard weft-knitting elastic silk fabric is high in quality and obvious in hollow out.
