Abstract
Disclosed are artificial turfs having a nonwoven backing layer and a plurality of turf fibers extending through the nonwoven backing layer such that a face side portion of the turf fibers extends from the face side of the nonwoven backing layer and a back side portion of the turf fibers extends from the back side of the nonwoven backing layer, wherein at least a portion of the back side portion of turf fibers are bonded to themselves. Also disclosed herein are the methods of making the same.
Claims18
An artificial turf, consisting of:
- a homogeneous nonwoven backing layer having a face side and a back side, wherein the homogeneous nonwoven backing layer comprises low-melt fibers having a melting point from about 100° C. to about 180° C. and high-melt fibers having a higher melting point than the low-melt fibers;
- and
- a plurality of turf fibers extending through the homogeneous nonwoven backing layer such that a face side portion of the plurality of turf fibers extends from the face side of the homogeneous nonwoven backing layer and a back side portion of the plurality of turf fibers extends from the back side of the homogeneous nonwoven backing layer, wherein at least a portion of the back side portion of turf fibers are bonded to themselves, wherein the plurality of turf fibers consists of only one type of a single polymer fiber being selected from the group consisting of nylon, polyester, polypropylene (PP), polyethylene (PE), polyurethane (PU), polyvinyl chloride (PVC), polyethylene terephthalate (PET), polypropylene terephthalate PPT), polybutylene terephthalate (PBT), and polytrimethylene terephthalate (PTT),
- wherein melted low-melt fibers in the homogeneous nonwoven backing layer form globules of the melted low-melt fibers at crossover points where low-melt fibers and high-melt fibers-intersect.
