Title
(EN) ADSORBENT MATERIAL
(FR) MATÉRIAU ADSORBANT
Abstract
(EN) A flexible material is disclosed comprising a flexible substrate, a sorbent comprising zirconium hydroxide and a binder, wherein the solids weight ratio of the binder to the zirconium hydroxide is in the range 1 : 1 to 1 : 120. Also disclosed is a process for production of a fabric, comprising: providing a flexible material, providing at least one sorbent dispersion comprising zirconium hydroxide and a binder, applying the sorbent dispersion to the flexible material to produce a treated flexible material, squeezing the treated flexible material under pressure, and passing the pressed treated flexible material through a stenter.
(FR) L'invention concerne un matériau souple comprenant un substrat souple, un sorbant comprenant de l'hydroxyde de zirconium et un liant, le rapport pondéral des solides du liant à l'hydroxyde de zirconium étant dans la plage 1 : 1 à 1 : 120. L'invention concerne également un processus de production d'un tissu, comprenant : la fourniture d'un matériau flexible, la fourniture d'au moins une dispersion de sorbant comprenant de l'hydroxyde de zirconium et un liant, l'application de la dispersion de sorbant sur le matériau flexible pour produire un matériau flexible traité, le pressage du matériau flexible traité sous pression, et le passage du matériau flexible traité pressé à travers un orifice d'entrée.
