PROBLEM TO BE SOLVED: To provide a tufted mat made of a polyolefin, suitable for artificial turf and carpet, having light weight and excellent water resistance, closely contacting with the laying base without causing undulation owing to its soft texture, free from the falling-off of the pile yarn and having excellent durability and good recycling property. SOLUTION: A primary base cloth 2 made of a polyolefin is tufted with a pile yarn 3 made of a polyolefin to form a pile cloth 4 and the pile yarn 3 is bonded to the primary base cloth 2 with a bonding polyolefin 6 having a low melting point to form a tufted mat 1. The polyolefins used in the process are polyethylenes, ethylene-α-olefin copolymers and/or polypropylenes polymerized by a metallocene catalyst. COPYRIGHT: (C)2005,JPO&NCIPI
