US 2006/0141223 A1 · Enhancing the watertightness of textile sheetlike constructions, textile sheetlike constructions thus finished and use thereof

Abstract

The present invention relates to textile sheetlike constructions having an enhanced watertightness and also to a process for producing them. It was found that, surprisingly, the watertightness of porous textile sheetlike constructions is enhanced when a coating of hydrophobic particles having an average particle size in the range from 0.02 to 100 μm is applied to the surfaces of the fibers. The textile sheetlike constructions can be used for example as textile building materials or for producing tents, umbrellas or the like.

Dependent claims

A process for enhancing the watertightness of a porous textile sheetlike construction having fibers, comprising:

applying to the textile sheetlike construction a suspension of hydrophobic particles or nonhydrophobic particles having an average particle size in the range from 0.02 to 100 μm in a solvent, followed by removing the solvent, to fix the particles to the fibers of the textile sheetlike construction and provide the surfaces of the fibers with a structure composed of elevations and/or depressions, wherein the elevations have a spacing in the range from 20 nm to 100 μm and a height in the range from 20 nm to 100 μm, and subsequently hydrophobicizing the nonhydrophobic particles.

Dependencies are inferred from the claim text.
