Cotton　fabric　composites　were　designed　to　be　protected　by　fire　safe　thermoplastic　polyurethane　(TPU)　composites　for　developing　electromagnetic　interference　(EMI)　shielding　polymer　composites　with　superior　mechanical　properties.　Herein,　the　as-prepared　MXene　was　coated　onto　the　fiber　surface　of　cotton　and　then　thermally　compressed　with　TPU　composites,　which　were　filled　with　the　sodium　dodecyl　sulfate　modified　layered　double　hydroxides　functionalized　the　short　carbon　fiber　hybrids　through　melt　blending　method.　Then,　a　series　of　highly　fire　safe　cotton/TPU　hierarchical　composites　were　constructed　by　a　designed　thermal　compression　technique.　For　instance,　the　obtained　cotton/TPU　hierarchical　sample　showed　greatly　reduced　peak　of　heat　release　rate,　peak　of　carbon　monoxide　production　rate　and　peak　of　carbon　dioxide　production　rate　of　TPU　by　50.1%,　52.1%　and　55.4%,　respectively.　Furthermore,　the　cotton/TPU　hierarchical　composites　possessed　the　EMI　shielding　effectiveness　of　40.0　dB　in　the　X　band　and　54.6　dB　in　the　K　band.　The　mechanical　property　of　the　cotton/TPU　hierarchical　composites　was　also　reinforced,　where　the　elongation　at　break　and　toughness　values　of　the　TPU/SCF/mLDH1/C2　hierarchical　composite　were　21.47　and　18.30　times　higher　than　those　of　pure　TPU,　respectively.　These　mechanically　strong　hierarchical　composites　have　brought　a　promising　attempt　to　broaden　their　practical　application,　removing　the　fire　hazards　and　electromagnetic　waves　radiation　from　the　environment.
