    摘要: A disclosed process for producing granular infill material for a synthetic turf surface includes providing scraps of a composite material comprising a textile support. A coating of the textile support includes a polymeric material. A weight percentage of the textile support is greater than or equal to 5% of a total weight of the composite material. The production process includes grinding the scraps to obtain scrap pieces, preparing a mixture comprising the scrap pieces, and heating the mixture to obtain a blend comprising the polymeric material in a softened state and pieces of the textile support dispersed in the polymeric matrix. A plurality of solid granules may be obtained from the blend to make the granular infill material. Each granule includes a polymeric matrix including the polymeric materials and a reinforcing filler dispersed in the polymeric matrix. The reinforcing filler may include pieces of the textile support.
