A method of coating a hydrophobic fibrous material with an amphiphilic polyelectrolyte which involves coating the hydrophobic fibrous material with a foam under conditions sufficient to substantially uniformly coat the hydrophilic fibrous material with the amphiphilic polyelectrolyte. The foam is generated from a solution of an amphiphilic polyelectrolyte in water. The hydrophobic fibrous material may be a polyolefin, such as polyethylene or polypropylene. The hydrophobic fibrous material also may be a nonwoven web, such as a meltblown or spunbonded nonwoven web. When the hydrophobic fibrous material is a nonwoven web, the web typically is coated with the foam, vacuum extracted, nipped, and dried.

L'invention porte sur un procédé de revêtement d'un matériau fibreux hydrophobe avec un polyélectrolyte amphiphile, qui consiste à revêtir le matériau fibreux hydrophobe d'une mousse dans des conditions permettant de revêtir de manière sensiblement uniforme le matériau fibreux hydrophobe de polyélectrolyte amphiphile. La mousse est composée d'une solution de polyélectrolyte amphiphile et d'eau. Le matériau fibreux hydrophobe peut être une polyéfine, telle qu'un polyéthylène ou un polypropylène. Le matériau fibreux hydrophobe peut également être un voile non tissé, tel qu'un voile non tissé produit par fusion-soufflage, ou un voile non tissé "spunbonded". Si le matériau fibreux hydrophobe est un voile non tissé, le voile est habituellement revêtu de la mousse, soumis à une extraction par aspiration, pincé et séché.
