CA 2257272

This invention relates to a new nonwoven material which has very high Frazier permeability while having substantial hydrostatic head liquid barrier properties. The material is comprised of fibers which are approximately one denier and finer fibers which have sufficient strength properties so as not to need a support scrim. The fabric is quite comfortable because of its breathability, quite soft because of its construction, and protective from liquids from rain to hazardous chemicals.

Nouveau matériau non tissé présentant une perméabilité de Frazier très élevée tout en présentant des propriétés barrière de liquide à charge hydrostatique substantielle. Ce matériau est composé de fibres d'environ un denier et de fibres plus fines dont les caractéristiques de résistance sont suffisamment importantes pour qu'elles ne nécessitent pas de renfort tissé. Cette étoffe est très confortable en raison de sa perméabilité à l'air et très souple en raison de sa structure, et assure une protection par rapport aux liquides allant de la pluie aux produits chimiques dangereux.
