The present disclosure provides: a non-woven fabric for a sterilization packaging material, the non-woven fabric being capable of being compatible with all sterilization treatment methods and maintaining a sterile state in the interior without breaking even in a variety of environments in which the non-woven fabric can be assumed to be used as a sterilization packaging material; and a non-woven fabric for a sterilization packaging material, the non-woven fabric achieving both easy-peel properties that enable easy handling without breakage and barrier properties for retaining the sterile state in the interior.

Nonwoven fabric for sterilization packaging material

Provided is a device () for drying a columnar structure () supported upright on a supporting surface (), wherein a feeding part () for feeding drying gas toward the supporting surface () and a discharge part () for discharging the fed drying gas are both provided in an opposing surface () facing the supporting surface (). A plurality of feeding parts () and a plurality of discharge parts () are preferably provided, and the plurality of discharge parts () are preferably symmetrically disposed around one feeding part ().

Drying device for columnar structure, and method for manufacturing columnar structure

The present invention provides a novel packaging material for sterilization which has processing suitability as a packaging material, is compatible with all sterilization processing methods such as those performed under high-temperature conditions, has small variation in shapes and dimensions, and is capable of maintaining an internal sterilized condition. This packaging material for sterilization is configured from at least two layers of laminated non-woven fabrics comprising a non-woven fabric layer (I) formed of continuous long fibers having an average fiber diameter of 5-30 &#x3bc;m and a non-woven fabric layer (II) formed of ultra-fine fibers having an average fiber diameter of 0.1-4 &#x3bc;m.
