Title (EN) BI-ELASTIC DOWN-PROOF NON-WOVEN INSERT
(FR) DOUBLURE EN NON-TISSÉ BI-ÉLASTIQUE ÉTANCHE AU DUVET
(DE) BI-ELASTISCHE DAUNENDICHTE VLIESSTOFFEINLAGE
Abstract:
(EN) The invention relates to a bi-elastic insert comprising a melt-blown non-woven material containing melt-spun melt-blown polyurethane fibers, the non-woven material being coated on at least one face with foam that contains vinyl acetate copolymer and/or polyacrylate and/or polyurethane. The insert can be produced to have a low weight per unit area and to be yet down-proof, as well as to have the air permeability and tear resistance required for good wear and performance characteristics.
(FR) L’invention concerne une doublure bi-élastique comprenant un non-tissé obtenu par fusion-soufflage contenant des fibres de polyuréthane filées par fusion-soufflage, le non-tissé présentant au moins sur un côté un revêtement de mousse qui contient un copolymère d’acétate de vinyle et/ou du polyacrylate et/ou du polyuréthane. La doublure peut être produite à un faible poids par mètre carré tout en présentant une étanchéité au duvet ainsi que la perméabilité à l’air et la résistance au déchirement nécessaires pour de bonnes propriétés de port et d’utilisation.
(DE) Bi-elastische Einlage umfassend einen Meltblown-Vliesstoff enthaltend schmelzgesponnene Meltblown-Polyurethan-Fasern, wobei der Vliesstoff auf zumindest einer Seite eine Schaumbeschichtung aufweist, die Vinylacetat- Copolymer und/oder Polyacrylat und/oder Polyurethan enthält. Die Einlage kann mit leichtem Flächengewicht gefertigt werden und dennoch gleichzeitig Daunendichtigkeit sowie eine für gute Trage- und Gebrauchseigenschaften erforderliche Luftdurchlässigkeit und Reißfestigkeit aufweisen.
