A shape memory fiber was prepared and a corresponding shape memory fabric was
fabricated by knitting using the prepared shape memory fiber. Both the fiber and fabric
showed good shape memory properties. The prepared fiber had much higher mechanical
strength than that of corresponding shape memory films due to molecular orientation caused
by the spinning process. The biological evaluations of the prepared shape memory fabric
were preliminarily assessed in terms of cytotoxicity, hemolysis, sensitization and dermal
irritant. The test results show that the shape memory fabric is not cytotoxic, hemolytic,
sensitive, or irritant. Due to the special format of shape memory fiber/fabric being more
compatible with human bodies compared with shape memory films or bulks, the shape
memory fiber/fabric may find broad application in biomedical areas such as artificial tendon,
artificial cornea, hernia repair, artificial bone joints, orthodontics, scaffold material, and
wound dressing.
