         9 . The fibre according to  claim 1 , wherein the fibre is a multifilament fibre. 
     
     
         10 . The fibre according to  claim 9 , having a yarn denier of approximately 400 to 100. 
     
     
         11 . The fibre according to  claim 9 , wherein the multifilament fibre is comprised of up to approximately 200 individual filaments/strands. 
     
     
         12 . The fibre according to  claim 1 , wherein the IR reflective pigment is anyone of Colanyal™ Oxide Yellow BV531, Colanyal™ Scarlet GO532, Colanyl™ Oxide Red G531 or Colanyl™ Oxide Blue COR531, or titanium dioxide, or mica, or silicon dioxide, or a combination thereof. 
     
     
         13 . The fibre according to  claims1 , wherein the IR reflective additive is titanium dioxide, mica, or silicon dioxide, or a combination thereof. 
     
     
         14 . A fabric for use as a shade cloth comprising a plurality of warp knitted fibres according to  claim 1 . 
     
     
         15 . The fabric according to  claim 14  wherein the fibre filaments are warp knitted on a raschel knitting machine, or woven, or tufted. 
     
     
         16 . The fabric according to  claim 14  having a warp density of approximately 4 to 12 gauge.
