(57) [Summary] [Problems] A collagen nonwoven fabric obtained by a conventional method has a problem that a part having low strength is partially generated, and a nonwoven fabric having a uniform thickness cannot be obtained. In addition, the conventional manufacturing process requires complicated work, and even if it can be performed at a laboratory level, industrial production is difficult. An object of the present invention is to provide a simple method for producing a nonwoven fabric in which collagen is uniformly dispersed. A second layer in which a plurality of similar collagen filaments are arranged in parallel on a first layer in which a plurality of collagen filaments spun using a solubilized collagen solution as a spinning solution is arranged in parallel. Collagen nonwoven fabrics in which the layers are laminated so that the direction of arrangement of the filaments of the first layer and the direction of arrangement of the filaments of the second layer are at an angle, and a method and an apparatus for producing the same . |
