METHOD FOR PRODUCING A FLOOR COVERING (INCLUDING CARPET AND CARPET TILE) WITH POSITIVE DEFINED RECYCLED CONTENT

摘要

The present invention relates to a method for producing floor covering (including carpet and carpet tiles) with recycled content, comprising the steps of gaining CaCO3 from ground or surface water during a softening process by adding a grain to the water, grafting the CaCO3 to the grain, adding the CaCO3 to the (fluid) backing material for a carpet or carpet tile (precoat or heavy coating layer), using the thus obtained backing material in a carpet or carpet tile manufacturing process, wherein the grain comprises essentially CaCO3.
