COMPOSITE BASE FABRIC AND METHOD FOR PRODUCING THE SAME

PROBLEM TO BE SOLVED: To provide a composite base fabric in which a non-woven fabric with nanofibers can be efficiently and firmly adhesively bonded to surfaces of various base material fabrics, and which also has high productivity; and to provide a method for producing the composite base fabric.SOLUTION: A base layer 12 is impregnated with a coating solution 16 including a hot-melt resin 16a, and is dried, whereby the surfaces of the fibers 12b included in the base layer 12 and portions between the fibers 12b are coated with the hot-melt resin 16a. Electrospinning is performed using a nanospinning solution obtained by dissolving a raw resin 26a for forming a nanofiber 14a in a solvent, to form a non-woven fabric layer 14 with the nanofiber 14a by lamination. The base layer 12 and the non-woven fabric layer 14 are allowed to overlap each other, and are heated and pressurized to thermally melt the hot-melt resin 16a to thermally fuse the base layer 12 and the non-woven fabric layer 14.SELECTED DRAWING: Figure 1 【課題】様々な基材布の表面に効率よく強固にナノ繊維の不織布を接着することができ、生産性も高い複合基布及びその製造方法を提供する。【解決手段】基材層１２に、ホットメルト系樹脂１６ａから成るコーティング溶液１６を含浸させて乾燥し、基材層１２を構成する繊維１２ｂの表面及びそれらの繊維１２ｂ間に、ホットメルト系樹脂１６ａをコーティングする。ナノ繊維１４ａを形成するための原料樹脂２６ａが溶媒に溶解して成るナノ紡糸溶液を用いて電界紡糸を行い、ナノ繊維１４ａの不織布層１４を積層形成する。基材層１２と不織布層１４を重ね合わせ、加熱及び加圧してホットメルト系樹脂１６ａを熱溶融し、基材層１２と不織布層１４を熱融着させる。【選択図】図１
