The present invention relates to synthetic fibers and artificial lawn comprising such a fibre. More particularly, the invention relates to grass-like monofilament type fibers having a curved cross section and an artificial grass lawn, especially an artificial grass sports field, comprising such a fibre. According to an aspect of the invention, a synthetic fibre is provided of the monofilament type for use in an artificial lawn, in particular an artificial sports lawn, which synthetic fibre has a curved cross section, wherein the synthetic fibre has a centre line arc length to maximum thickness of less than 8, preferably between 4.5 and 3.8, and even more preferably between 4.4 and 4.0. In an other aspect of the invention, a synthetic fibre is provided of the monofilament type for use in an artificial lawn, in particular an artificial sports lawn, which synthetic fibre has a curved cross section, wherein the circumferential surface of the fibre is provided with a wave shaped pattern.

An improved heavy denier fibrillated polymer carpet yarn is densely knit, deknit and heat treated. An improved carpet face yarn is provided in an omnidirectional carpet pile.

Knit-deknit yarn and method and apparatus for making same

The disclosure relates to a carpet product, a process for manufacturing carpet, and an apparatus used in a carpet manufacturing process. The carpet product is made from tufted polymer filament yarn and includes a sheet of extruded polypropylene, integrally fused to the individual yarn filaments of the yarn back loops. The yarn fibers are substantially all secured to the integrally fused sheet so that the carpet resists fuzzing. The process includes providing a carpet base having a primary backing penetrated by yarn, applying heat to the underside of the base, extruding a heated sheet of polymer and continuously contacting the heated extruded sheet of polymer with the base thereby integrally fusing the base to the extruded sheet. The apparatus includes a source of carpet precursor, a heated cylinder for heating the underside of the carpet, an extruder and a casting roll against which the extruded sheet and heated carpet are pressed.
