    摘要: Disclosed is a continuous process of non-compressively and uniformly applying a liquid saturant throughout a permeable sheet. The process includes the steps of: 1) providing a continuously advancing permeable sheet having a first surface and a second surface, 2) depositing a substantially laminar flowing curtain of a liquid saturant generally across and onto the first surface of the continuously advancing permeable sheet, 3) applying a vacuum to the second surface of the continuously advancing permeable sheet, and 4) drawing a substantial portion of the liquid saturant through the permeable sheet to generate a substantially uniform distribution of liquid saturant throughout the permeable sheet. The process may also include the step of drying the liquid saturated permeable sheet. The dry bulk of the liquid saturant treated permeable sheet may be within about 15 percent of the dry bulk of an identical untreated permeable sheet. Also disclosed is a non-compressively and uniformly liquid saturant treated permeable sheet and an apparatus for non-compressively and uniformly applying a liquid saturant throughout a permeable sheet.
