Title:
NON-WOVEN FABRIC FOR STERILIZATION PACKAGING MATERIAL
Document Type and Number:
WIPO Patent Application WO/2020/196340
Kind Code:
A1
Abstract:
The present invention 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. The non-woven fabric for a sterilization packaging material according to the present invention is characterized in having, as an obverse-layer heat seal surface, a fiber layer (I) that has a void ratio of 30-60% inclusive, and having, as a barrier layer, a fiber layer (II) that has a fiber specific surface area ranging from 1.0 m2/g to 10 m2/g and has a one-centimeter-equivalent fiber count of 800-1,000,000 inclusive per milligram, the fiber layer (I) and the fiber layer (II) being laminated. In addition, the non-woven fabric for a sterilization packaging material is characterized in having a weight-average fiber diameter of 3-30 μm inclusive and a formation coefficient of 1.0-5.0 inclusive.
