extile structures with negative Poisson’s ratio are a
special class of textile materials. Known as auxetic
textiles, they transversally expand when axially stretched
or transversally contract when compressed. This
nonconventional deformation behavior leads to a series of
special properties of textile structures such as formation of
dome shape under out of plane bending, increase of pore
opening effect under extension, enhancement of energy
absorption ability and indentation effect under impact
force, etc. In this talk, different types of textile structures
with negative Poisson’s ratio which have been recently
developed at PolyU will be presented, including auxetic
plied and braided yarns, 2D and 3D auxetic weft and warp
knitted fabrics, uni-stretch and bi-stretch auxetic woven
fabrics, and 3D auxetic textile structure and composites.
Auxetic behavior and mechanical properties of these
textile structures obtained from both experimental
and theoretical analyses will be discussed. In addition,
potential applications of auxetic textiles in different areas
will be demonstrated.
