TUFTED NONWOVEN AND BONDED NONWOVEN

摘要

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 ia) at least bicomponent filaments 1 exhibit a core/sheath geometry wherein component 11 represents the core and component 12 represents the sheath or iß) at least bicomponent filaments 1 exhibit a side by side geometry wherein component 11 represents side 1 and component 12 represents side 2 or i?) 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 Tm(11 ) and the component 22 exhibits a melting temperature Tm(22), iii) the component 12 exhibits a melting temperature Tm(12), the component 21 exhibits a melting temperature Tm(21) and Tm(12) is higher than Tm(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 Tm(11 ) and Tm(22) > Tm(12) > Tm(21 ) and optionally wherein the face material is bonded to bicomponent filaments 2 by a solidified melt of component 21.
