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.

    Abstract: A nonwoven primary carpet backing includes thermoplastic polymer filaments or fibers bonded by means of a binder polymer. The backing includes at least a distinguishable thermoplastic woven layer, a distinguishable thermoplastic continuous layer, or a distinguishable nonwoven layer including filaments or fibers bonded by means of a binder polymer, which layer reduces the delamination strength of the backing, measured in accordance with DIN 54310, by at least 30% and preferably by at least 50%, with respect to the same backing without the distinguishable layer. Although the breaking strength of the untufted backing according to the invention is lower than that of untufted backings not including the distinguishable layer, the tufted backing according to the invention actually has a higher breaking strength and elongation than tufted backings not including the distinguishable layer.

    Abstract: A low-stretch and dimensionally stable floor covering (1) comprising polymer-containing pile material (2) which is retained to a polymer-containing primary backing (3), to the back of which an underlying secondary backing layer (5) is retained by means of an interleafing adhesive layer (4). The secondary backing layer (5) comprises a needled fibre structure of thermoplastic, polymer-containing, continuous or staple fibres being inter-fixated by heating. The adhesive layer (4) comprises an organic, polymer-containing binder which is activated by heat application. According to the invention, at least the secondary backing layer and/or the binder layer comprise a substantially re-usable material. After being formed, the carpet is wound onto so-called broadloom rollers and can, if desired, be cut partially into carpet tiles. Thus, carpet tiles and broadloom carpets can be manufactured in the same production process.
