Abstract
Provided is an artificial turf yarn having improved heat resistance, durability, softness and extensibility. The artificial turf yarn contains two components: an olefin block copolymer (OBC) and a linear low density polyethylene (LLDPE). The yarn includes from about 10 wt % to about 80 wt % of the OBC and from about 20 wt % to about 90 wt % of the LLDPE which produces an artificial turf yarn with improved softness and toughness while maintaining heat resistance.
Claims18
An artificial turf yarn comprising:
- from about 10 wt % to about 80 wt % of an olefin block copolymer (OBC) having a density from about 0.866 g/cc to less than 0.900 g/cc and from about 20 wt % to about 90 wt % of a linear low density polyethylene (LLDPE) having a density from 0.910 g/cc to 0.935 g/cc, the yarn having a shrinkage less than 8%.
An artificial turf yarn comprising:
- from about 10 wt % to about 80 wt % of an olefin block copolymer (OBC) having a density from about 0.866 g/cc to less than 0.900 g/cc and from about 20 wt % to about 90 wt % of a linear low density polyethylene (LLDPE) having a density from 0.910 g/cc to 0.935 g/cc, the yarn having a density less than 0.920 g/cc and a shrinkage less than 6%.
An artificial turf comprising:
- a backing substrate;
- and
