Abstract: The invention belongs to the field of textile machinery, and discloses weaving equipment and a weaving method of three-dimensional negative-poisson-ratio fabric. The weaving equipment of the three-dimensional negative-poisson-ratio fabric comprises a base, a yarn laying mechanism, an X-direction yarn storage frame, a Y-direction yarn storage frame, a laying yarn compaction mechanism and a Z-direction yarn binding mechanism. The weaving method comprises the steps that multi-layer yarns capable of forming a negative-poisson-ratio effect are laid in an X direction and a Y direction; the laid yarns in the X direction and the Y direction are bound by yarns in a Z direction; and an integral three-dimensional negative-poisson-ratio fabric structure is formed. The weaving equipment is simple in structure and convenient to operate, and damages the yarns less; the weaving method is flexible in technology; the edge of the fabric structure is closed; the integrity is good; the fabric laying thickness can be adjusted; the three-dimensional fabric with the negative-poisson-ratio performance can be woven; and positive-poisson-ratio fabric can also be woven.
