Sheath-core microporous polyamide 6 fibers via in situ foaming and bicomponent melt spinning for thermal insulation.
The development of thermal insulation materials that simultaneously integrate lightweight characteristics, mechanical robustness, and wearing comfort remains a formidable challenge. In this study, a facile strategy was proposed for the continuous fabrication of sheath-core microporous polyamide 6 fibers (MPA6 fibers) v...
