Title:
多層型銅系ゼオライト繊維医療用材料、医療用防護用品及びその製造方法
Document Type and Number:
Japanese Patent JP7197870
Kind Code:
B2
Abstract:
The present disclosure is to provide a medical material, protective equipment with both low cytotoxicity and high-efficiency antibacterial, antiviral properties and its manufacturing method. The multi-layer copper-based zeolite fiber medical material of the present disclosure includes a four-layer structure, including the outermost layer, the first intermediate layer, the second intermediate layer, and the innermost layer in sequence; the outermost layer and the second intermediate layer are copper-based zeolite fiber layer, the first intermediate layer is a hydrophobic fiber layer, and the innermost layer is a hydrophilic fiber layer; the pore size of the copper-based zeolite fiber layer of the outermost layer is greater than the pore size of the hydrophobic fiber layer of the first intermediate layer; the copper-based zeolite fiber layer contains copper-based zeolite and fiber threads, the fiber threads are formed by twisting fibers; the copper-based zeolite is independently dispersed on the fiber surface., and the mass of the copper-based zeolite decreases in a gradient from outside to inside along the radial interface of the fiber thread. The medical material and the prepared medical protective equipment of the present disclosure have multiple technical advantages of low cytotoxicity, high antibacterial and antiviral properties. It also has high efficiency in killing viruses (especially SARS-CoV-2) and sufficient biological safety, which is expected to reshape the medical masks industry standard, and has high theoretical and practical value.
