Absorbent material impregnation - brings fluid to compressed material for distribution through it by air extraction

摘要

The process is impregnate an absorbent material, by inserting it as a stack into a fluid-filled vessel, compresses the material before treatment. The fluid is introduced to the vessel and it passes through the material by extracting air from the stack. The system provides a simple process and simple equipment to ensure that an absorbent material is fully impregnated. It allows the use of paper, woven fabrics or non-wovens to be impregnated with cosmetic, pharmaceutical or technical fluids.
