Article suitable for household or industrial cleaning made of pile looped fabric comprising a yarn of thermoplastic material and process for the manufacture thereof

Abstract

Article suitable for household or industrial cleaning, comprising at least one pile fabric ( 500 ), wherein the pile fabric ( 500 ) comprises a ground portion ( 80 ) and at least one pile portion ( 70, 71 ), the ground portion ( 80 ) of the fabric ( 500 ) comprises a solidified/hardened material, consisting of a material obtained after having melted a yarn consisting of a thermoplastic material having a melting point between 120 and 180° C., and/or after having melted the lower melting component ( 82 ) of a bicomponent yarn comprising two materials ( 81, 82 ) with different melting point. The ground portion is stiffened in an effective manner and allows reliable fastening on a support. Also a corresponding method of manufacturing said article is disclosed, especially comprising Raschel type warp knitting.
