Claim Text:
1. A three dimensional negative Poisson's ratio spacer knitted fabric, wherein, the three dimensional negative Poisson's ratio spacer knitted fabric includes a first surface layer fabric, a second surface layer fabric, and a spacer yarn layer connecting the first surface layer fabric with the second surface layer fabric, and both the first surface layer fabric and the second surface layer fabric are surface structures having the negative Poisson's ratio effects; each of the first surface layer fabric and second surface layer fabric is any one of a re-entrant quadrangle mesh structure, a re-entrant hexagon mesh structure, a rotary triangle mesh structure, a rotary square mesh structure, a rotary rectangle mesh structure, a star honeycombed mesh structure, or a chiral honeycombed mesh structure.
