Polymeric yarn and method for manufacturing

Abstract

The invention relates to a yarn comprising polymeric filaments and/or polymeric staple fibers containing a filler, wherein said filler is a plurality of fibrils having an average length of between 50 μm and 200 μm.

1 . A yarn comprising polymeric filaments and/or polymeric staple fibers containing a filler, wherein said filler is a plurality of fibrils having an average length of between 50 μm and 200 μm. 
     
     
         2 . The yarn of  claim 1  wherein the average length of said plurality of fibrils is at most 180 μm, more preferably at most 150 μm. 
     
     
         3 . The yarn of  claim 1  wherein said average length of said plurality of fibrils is at least 75 μm, preferably at least 100 μm. 
     
     
         4 . The yarn of  claim 1  wherein the plurality of fibrils has a mass averaged fibril diameter of at most at most 20 μm, more preferably at most 15 μm, even more preferably at most 10 μm, most preferably at most 8 μm. 
     
     
         5 . The yarn of  claim 1  wherein the plurality of fibrils has a mass averaged fibril diameter is at least 1 μm, more preferably at least 3 μm. 
     
     
         6 . The yarn of  claim 1  wherein the fibrils are hard fibrils. 
     
     
         7 . The yarn of  claim 1  wherein the fibrils are hard fibrils having a Moh's hardness of at least 2.5. 
     
     
         8 . The yarn of  claim 1  wherein the polymer used to manufacture the polymeric filaments and/or staple fibers is a polyolefin, more preferably a polypropylene or a polyethylene. 
     
     
         9 . The yarn of  claim 1  wherein the polymer used to manufacture the polymeric filaments and/or staple fibers is an ultrahigh molecular weight polyethylene (UHMwPE). 
     
     
         10 . The yarn of  claim 1  wherein the polymeric filaments and/or polymeric staple fibers comprise between 0.1 wt % and 55 wt % of filler. 
     
     
         11 . A composite yarn containing one or more of any one of the yarns of  claim 1  and one or more further yarns, wherein the further yarns are preferably yarns manufactured from a glass, a metal or a ceramic material. 
     
     
         12 . Fabrics, architectural textiles, ropes, fishing lines and fishing nets, cargo nets, straps and restraints for shipping and aviation comprising the yarn of  claim 1 . 
     
     
         13 . Garments, in particular gloves, aprons, trousers, cuffs and sleeves comprising the yarn of  claim 1 . 
     
     
         14 . Protective products against injury by stabbing comprising the yarn of  claim 1 . 
     
     
         15 . Protective garments against injury by slashing comprising the yarn of  claim 1 .
