METHOD FOR MANUFACTURING A CARPET OR A RUG AND A CARPET OR RUG OBTAINED THEREBY
Method for manufacturing a carpet or a rug, comprising the following steps: the step (S 1 -S 2 ) of providing a primary backing ( 1 ), being a woven or non-woven layer comprising filaments ( 2 ) of polyethyleneterephthalate and copolymer of polyethyleneterephthalate, the coPET having a lower melting temperature than the PET and wherein said PET is available in said primary backing ( 1 ) in a higher amount than said coPET; the step of providing a glue layer ( 11 ) consisting for 50% or more out of coPET; the step of tufting yarn at least into said primary backing ( 1 ); the step of activating said glue layer ( 11 ) at least for partially fixing said yarn ( 12 ) on said primary backing ( 1 ). The invention also concerns carpets ( 16 ) and rugs that are obtained or obtainable by means of such method.
