Although　individual　carbon　nanotubes　(CNTs)　are　superior　to　polymer　chains,　the　mechanical　and　thermal　properties　of　CNT　fibers　(CNTFs)　remain　inferior　to　synthetic　fibers　because　of　the　failure　of　embedding　CNTs　effectively　in　superstructures.　Conventional　techniques　resulted　in　a　mild　improvement　of　target　properties　while　degrading　others.　Here,　a　double-drawing　technique　is　developed　to　rearrange　the　constituent　CNTs.　Consequently,　the　mechanical　and　thermal　properties　of　the　resulting　CNTFs　can　simultaneously　reach　their　highest　performances　with　specific　strength　~3.30　N　tex(-1)　(4.60　GPa),　work　of　rupture　~70　J　g(-1),　and　thermal　conductivity　~354　W　m(-1)　K-1　despite　starting　from　low-crystallinity　materials　(IG:ID　~　5).　The　processed　CNTFs　are　more　versatile　than　comparable　carbon　fiber,　Zylon　and　Dyneema.　On　the　basis　of　evidence　of　load　transfer　efficiency　on　individual　CNTs　measured　with　in　situ　stretching　Raman,　we　find　that　the　main　contributors　to　property　enhancements　are　the　increasing　of　the　effective　tube　contribution.
