         10 . The yarn of  claim 1 , wherein a twist direction of the plurality of monofilaments is the same as a twist direction of the multifilament or the spun yarn. 
     
     
         11 . The yarn of  claim 1 , wherein diameters of the plurality of monofilaments are 0.1-0.6 mm. 
     
     
         12 . The yarn of  claim 11  wherein the diameters of the plurality of monofilaments are 0.2 mm. 
     
     
         13 . The yarn of  claim 1  wherein the multifilament or the spun yarn has a linear density of 50-150 dtex. 
     
     
         14 . The yarn of  claim 1 , wherein the multifilament or the spun yarn is twisted or non-twisted. 
     
     
         15 . The yarn of  claim 1  having an overfeed of the multifilament or the spun yarn of 5-25% 
     
     
         16 . The yarn of  claim 1  wherein the yarn has an overfeed of the multifilament or the spun yarn of about 15%. 
     
     
         17 . The yarn of  claim 1  having a linear density of 200-600 tex. 
     
     
         18 . A method for manufacturing a yarn of  claim 1  comprising:
 providing a plurality of monofilaments and a multifilament or a spun yarn; 
 twisting the plurality of the monofilaments together, and simultaneously or afterwards; 
 winding the multifilament or the spun yarn around the plurality of the monofilaments; and 
 wherein the multifilament or the spun yarn comprises a bio-based material, a recycled bio-based material or a recycled synthetic material. 
 
     
     
         19 . An industrial textile comprising a yarn of  claim 1 .
