Title
(EN) INFILL MATERIAL FOR SYNTHETIC TURFS AND SYNTHETIC TURFS SO OBTAINED
(FR) MATÉRIAU DE REMPLISSAGE POUR GAZONS SYNTHÉTIQUES ET GAZONS SYNTHÉTIQUES AINSI OBTENUS
Abstract
(EN)
Synthetic turf (1) comprising a mat (2) equipped with a first face (2a), which in use is arranged next to a surface (50) to coat, and with a second face (2b) opposite to the first face (2a). The synthetic turf (1) comprises, furthermore, a plurality of filaments (3) knitted to the mat (2) and made of a synthetic material. Above the second face (2b) of the mat (2), furthermore, an infill material (10) is present that is arranged all around the filaments (3) of artificial material. The infill material (10) comprises, in particular at least one layer (15) consisting of a mixture of a predetermined amount of cereal husks, such as rice husks, husks of wheat, husks of rye, husks of oat, husks of spelt, or a combination thereof, and of at least one defibrated arboreus material which is resistant to microbial digestion, such as a loose final product from raw material based on coir, or sawdust of a wood obtained by a raw material with high content of lignin, such as Teck pulp material, Mahogany pulp material, Iroko pulp material, or a combination thereof (Fig.1).
(FR)
L'invention porte sur un gazon synthétique (1), qui comprend un matériau (2) équipé d'une première face (2a) qui, lors de l'utilisation, est disposée au voisinage d'une surface (50) à revêtir, et d'une deuxième face (2b) opposée à la première face (2a). Le gazon synthétique (1) comprend de plus une pluralité de filaments (3) tricotés sur le mat (2) et réalisés en un matériau synthétique. Au-dessus de la deuxième face (2b) du mat (2), en outre, un matériau de remplissage (10) est présent, lequel est disposé tout autour des filaments (3) de matériau artificiel. Le matériau de remplissage (10) comprend, en particulier, au moins une couche (15) comprenant un mélange d'une quantité prédéterminée de balles de céréales, telles que des balles de riz, des balles de blé, des balles de seigle, des balles d'avoine, des balles d'épeautre, ou une combinaison de celles-ci, et au moins un matériau d'arbre défibré qui est résistant à la digestion microbienne, tel qu'un produit final lâche venant d'une matière première à base de coir, ou de la sciure d'un bois obtenue à partir d'une matière première avec une haute teneur en lignine, telle qu'un matériau de pâte de teck, un matériau de pâte de mahogany, un matériau de pâte d'iroko, ou une combinaison de ceux-ci (figure 1).
