Shape memory fibers

This chapter writes up from the shape memory polymer (SMP) to the conventional shape memory polymer fiber (SMPF) by common spinning method like melt-spun, wet-spun, and dry-spun method. Mechanical properties of the fibers spun by different method will be introduced. Comparisons among shape memory fiber, spandex, and other common fibers will be stressed; then is introduction of shape memory property, stimulus, posttreatment, and evaluation method of shape memory fiber. The application in textiles will include textile processing ability of the fiber and how to combine shape memory functions into textiles. In differential shape memory fiber part, hollow fiber and conductive fiber will be introduced and its potential applications. Nanoscale shape memory fiber or nonwoven will be as an independent part for its novel properties of quick response, multifunction, etc. because of the nanoscale.
