PROBLEM TO BE SOLVED: To provide a shield member for a building material, consisting of a nanofiber laminate, having air-permeability, low light shielding property, and sufficient strength, and capable of being inexpensively manufactured, and a manufacturing apparatus therefor.SOLUTION: A first polymer adhesive in a fiber state is blown onto a base material which is a strong monofilament or multifilament woven or knitted fabric having a coarse mesh to form a finer mesh in the mesh of the base material and provide a reinforcement base material. A second polymer adhesive in a fiber state with a diameter of 500 nm to 10 μm is thinly blown onto the reinforcement base material so as not to close clearances of the mesh to laminate nanofibers onto the second polymer adhesive, and the reinforcement base material and the nanofibers are bonded to each other. Thus, there is provided a nanofiber laminated thin film shield member for a building material, which has air permeability as well as light permeability, and collects pollen particles, while the second polymer adhesive does not close clearances of the nanofibers.COPYRIGHT: (C)2014,JPO&INPIT【課題】ナノファイバーの積層体からなる通気性があり、遮光性が低く、十分な強度を有し、安価に製造できる建材用の遮蔽部材及びその製造装置を提供する。【解決手段】モノ又はマルチフィラメントの織編物で粗い目の強度のある基材に、第1高分子接着剤をファイバー状にして基材に吹き付けて基材の目に更に細かい網目を形成して補強基材とし、補強基材に第2高分子接着剤を500nmから10μmのファイバー状の径とした接着剤を網目の隙間を塞がないように薄く吹き付け、第2高分子接着剤上にナノファイバーを積層して補強基材とナノファイバーとを接着し、第2高分子接着剤がナノファイバーの隙間も塞がないようにして通気性と光透過性とを有し花粉粒子を捕集するナノファイバーを積層した建材用の薄膜遮蔽部材。【選択図】図1
