Abstract

A tufted nonwoven with improved stitch holding, a bonded nonwoven and methods for their manufacture are described. The tufted nonwoven with improved stitch holding comprises a face material which tufts a bonded nonwoven comprising a mixture of a plurality of bicomponent filaments 1 with a plurality of bicomponent filaments 2 wherein iα) at least bicomponent filaments 1 exhibit a core/sheath geometry wherein component 11 represents the core and component 12 represents the sheath or iβ) at least bicomponent filaments 1 exhibit a side by side geometry wherein component 11 represents side 1 and component 12 represents side 2 or iγ) at least bicomponent filaments 1 exhibit an islands in the sea geometry wherein component 11 represents the islands and component 12 represents the sea ii) the component 11 exhibits a melting temperature T_m(11) and the component 22 exhibits a melting temperature T_m(22), iii) the component 12 exhibits a melting temperature T_m(12), the component 21 exhibits a melting temperature T_m(21) and T_m(12) is higher than T_m(21) and iv) the melting temperatures of both component 11 and 22 and the melting temperatures of components 12 and 21 obey to the relation both T_m(11) and T_m(22)>T_m(12)>T_m(21) an wherein the face material is bonded to bicomponent filaments 1 and 2 by a solidified melt of components 12 and 21.
