Patent Searching and Data

Document Type and Number:
Japanese Patent JP2001522000
Kind Code:
A tissue sheet is made using a modified wet pressing process employing an integrally sealed air press. After initial formation and conventional vacuum dewatering, the wet web is conformed to the surface contour of a relatively 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 the web of at least 500 SCFM/in2, the air press noncompressively dewaters the wet web to a consistency of about 30 to about 40 percent prior to a Yankee dryer. The web is dried to substantially preserve its three-dimensional, throughdried-like texture. The resulting web has an exceptionally high degree of bulk and absorbency not previously found in wet-pressed products.
