摘要:
Die vorliegende Erfindung betrifft ein Verfahren zur Herstellung von querelastischen Materialbahnen, bestehend aus einer Oberlage, einer Unterlage sowie einer vorgereckten, mit dem Ober- Und Untervliesstoff (9,10) verbundenen elastischen Zwischenlage (7), bei welchem man den Obervliesstoff und den Untervliesstoff über Walzen zwischen zwei seitlichen, mit Haken (5) versehenen umlaufenden Bändchentransportketten (1,2) zusammenbringt, mit Hilfe eines Bändchenlegers (6) elastische Bändchen (7) zwischen den Transportketten (1,2) hin- und herführt und dabei um die Haken (5) schlingt, so dass parallele Lagen quer zur Umlaufrichtung der Transportketten entstehen, wobei die Bändchen vorgereckt sind. Oberlage und Unterlage werden gegen die Bändchen gedrückt und die Lagen miteinander verklebt oder verschweißt.

A sheet for civil engineering and construction comprising a lubricant layer sandwiched between two or more substrates, whereinat least one of the substrates has a coefficient of kinetic friction (µ) of 0.45 or lower; and a sheet for civil engineering and construction comprising a lubricant layer sandwiched between two or more substrates, wherein at least one of the substrates is a lattice-like substrate.
摘要:
A composite fabric garment (100) includes a first garment portion (105) disposed in one or more upper regions of the fabric garment, i.e. those regions relatively more likely in use to be exposed to wind and rain, and a second garment portion (110) disposed in one or more lower regions of the fabric garment, i.e. those regions relatively less likely in use to be exposed to wind and rain. The first garment portion is formed of a first composite fabric having first inner (120) and outer (115) fabric layers and a first intermediate barrier layer (125) disposed between and bonded to at least one of the first inner and outer fabric layers, the first intermediate barrier layer being breathable and substantially impermeable to wind and liquid water. The second garment portion is formed of a second composite fabric formed of second inner and outer fabric layers and having predetermined air permeability. In one embodiment, the second garment portion further includes a second intermediate, breathable, air-permeable barrier layer disposed between and bonded to at least one of the second inner and outer fabric layers. In another embodiment, the second garment portion is formed of a composite fabric having controlled air permeability in a non-laminate absent a barrier.
