  • Patent number: 10448678
    Abstract: A front panel for a sports bra has an interior liner layer having a back face contacting a wearer's skin, and an exterior shell layer having a back face facing a front face of the interior liner layer and coupled to the interior liner layer. A film layer is located between the front face of the interior liner layer and the back face of the exterior shell layer. The film layer becomes stiffer as a frequency of movement of a wearer's breasts increases, thereby absorbing forces caused by the movement of the wearer's breasts. A method for constructing a sports bra front panel with a thermally-induced shape memory polymer that exhibits viscoelastic properties when at body temperature and stiffens to absorb between about 0.015 N and about 0.03 N of force at frequencies of breast movement of between about 6 Hz and about 15 Hz is also disclosed.
