摘要：A tissue sheet is made using a modified wet pressing machine in a modified wetpressing process employing an integrally sealed air press. After initial formation andconventional vacuum dewatering, the wet web is conformed to the surface contour of arelatively coarse fabric to give the web a textured surface. By creating a pressure

differential across the web of at least 30 inches of mercury and an air stream through theweb of at least 500 SCFM/in<2>, the air press noncompressively dewaters the wet webto a consistency of about 30 to about 40 percent prior to a heated drying cylinder. Theweb is dried to substantially preserve its three-dimensional, throughdried-like texture.The process provides a web having an exceptionally high degree of bulk and absorbencynot expected in wet-pressed products.
