Title
(EN) NONWOVEN BACKING AND CARPET COMPRISING SAME
(FR) SUBSTRAT NON TISSE ET MOQUETTE LE COMPRENANT
Abstract
(EN)
The invention pertains to a nonwoven primary carpet backing comprising thermoplastic polymer filaments or fibres bonded by means of a binder polymer, wherein the backing comprises at least a distinguishable thermoplastic woven layer, a distinguishable thermoplastic continuous layer, or a distinguishable nonwoven layer also comprising filaments or fibres 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 said distinguishable layer. Although the breaking strength of the untufted backing according to the invention is lower than that of untufted prior art backings, the tufted backing according to the invention actually has a higher breaking strength and elongation than tufted prior art backings.
(FR)
L'invention porte sur un substrat de moquette non tissé, de filaments ou fibres de polymère thermoplastique, liées par un polymère, et comportant: une couche discernable de thermoplastique tissé et une couche discernable continue de thermoplastique ou une couche discernable de non tissé également faite de filaments ou fibres liées par un polymère. Les forces de délaminage du substrat selon DIN 54310 sont réduites d'au moins 30 % et de préférence d'au moins 50 % par rapport à un substrat semblable, mais ne comportant pas lesdites couches discernables. Bien que la résistance à la rupture du substrat non touffeté de l'invention soit moindre que celle des substrats non touffeté de conception antérieure, le substrat touffeté de l'invention présente une résistance à la rupture et une élongation supérieure à celles des substrats touffetés de conception antérieure.
