not closed in this procedure, the diffusion capacity (breathability) of the material remains virtually unaffected by the hydrophobing treatment. Objective: The [...] contact time Effect: In general, the deeper the Appretur penetrates into the material, the better the effect will be. The ideal degree of penetration has to be [...] and therefore also the achievable improvement are depending directly on the material thickness, density and penetration depth. The Appretur is applied in a curtain
