Title:
【発明の名称】セルロース繊維構造の多重ゾーン制限オリフィス乾燥と、そのための装置と、これによって製造されるセルロース繊維構造
Document Type and Number:
Japanese Patent JPH11507417
Kind Code:
A
Abstract:
A limiting orifice through-air-drying apparatus for papermaking or other absorbent embryonic webs. The apparatus has a first zone (41) and a second zone (42). The first (41) zone is maintained at a differential pressure less than the breakthrough pressure, while the second zone (42) is maintained at a differential pressure greater than the breakthrough pressure. The residence time of the embryonic web to be dried with the apparatus is maintained at preferably less than 35 milliseconds on the first zone. Using the dual zone system described above, the overall energy required to run the apparatus can be reduced.
