Tufted nonwoven, bonded nonwoven, methods for their manufacture and uses |
摘要 |
A tufted nonwoven includes a face material which tufts a bonded nonwoven having a mixture of a plurality of bicomponent filaments 1 with a plurality of bicomponent filaments 2. At least bicomponent filaments 1 have component 11 and component 12. Component 11 exhibits a melting temperature Tm(11), and component 22 of the bicomponent filaments 2 exhibits a melting temperature Tm(22). Component 12 exhibits a melting temperature Tm(12), and component 21 of the second bicomponent filaments exhibits a melting temperature Tm(21), and Tm(12) is higher than Tm(21). The melting temperatures of components 11 and 22 and the melting temperatures of components 12 and 21 obey a relationship in which Tm(11) and Tm(22)>Tm(12)>first Tm(21) and optionally wherein the face material is bonded to bicomponent filaments 2 by a solidified melt of component 21. Also described are a bonded nonwoven and methods for their manufacture.
