Abstract
This present application relates to a three dimensional negative Poisson's ratio spacer knitted fabric and a method for making the same; the 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, both the first surface layer fabric and the second surface layer fabric are bi-dimensional structures having the negative Poisson's ratio effects; the method is to compress and/or stretch a three dimensional mesh spacer knitted base fabric along one or two plane directions to form a structures having the negative Poisson's ratio effects. The advantages of the present application include low making cost, simple operation method, significant negative Poisson's ratio effects, good elastic recovery, and high practical application value.
