    • PROBLEM TO BE SOLVED: To provide a sheet material that is produced by directly blowing a hot gas mainly including superheated steam via the air-permeating belt zone restraining the free shrinkage of the sheet into the moisture inside the sheet to cause the instantaneous vaporization (in a pressure flow) of the moisture whereby the sheet is made porous and disclose a method of producing the same and a drier for the foamed sheet.
      SOLUTION: A moistened sheet material 35 is nipped between the externally heated rotor 1 equipped with an outlet 19 for blowing a hot gas from the circumferential direction and the air-permeating endless fabric 36 that moves synchronously to the rotation of the rotor 1 under such a tension that can restrain the drying shrinkage of the sheet whereby the moisture in the sheet is promptly and directly vaporized and the sheet is made porous.

    • 要解决的问题:提供一种片材,其通过空气渗透带区域直接吹送主要包括过热蒸汽的热气体,从而将片材的自由收缩抑制在片材内部的水分中,从而引起瞬时蒸发(在 压力流),从而使片材多孔,并公开了其制造方法和用于发泡片材的干燥器。 解决方案:将湿润的片材35夹在外部加热的转子1之间,该转子1装有用于从圆周方向吹出热气体的出口19和与这样的转子1同步旋转的空气渗透环形织物36 可以抑制片材的干燥收缩的张力,由此片材中的水分迅速并直接蒸发,并且片材被制成多孔的。
