Abstract
Official abstract text for this publication.
A method for producing yarns separated from reinforcing fiber strands including a process of intermittently separating fibers of the reinforcing fiber strands.
First claim
Opening claim text (preview).
1 . A method for producing yarns separated from reinforcing fiber strands comprising: a process of intermittently separating fibers of the reinforcing fiber strands, wherein the process of intermittently separating fibers of the reinforcing fiber strands is performed using a separating jig, and wherein the separating jig is provided with a separating portion having a concave-convex shape and the following conditions (1) and (2) are satisfied, (1) a height of a convex portion set to one or more times a whole thickness of the strands, and (2) curvature radius R of a distal end of the convex portion set to 0.01 mm to 50 mm. 2 . (canceled) 3 . The method for producing yarns separated from the reinforcing fiber strands according to claim 1 , wherein the separating jig has a plurality of the separating portions. 4 . The method for producing yarns separated from the reinforcing fiber strands according to claim 1 , wherein the reinforcing fiber strands are brought into contact with the separating portion of the separating jig a plurality of times. 5 . The method for producing yarns separated from the reinforcing fiber strands according to claim 1 , wherein the reinforcing fiber strands are carbon fiber strands. 6 . The method for producing yarns separated from reinforcing fiber strands according to claim 1 , wherein, when the reinforcing fiber strands are brought into contact with the separating jig, a whole width of the reinforcing fiber strands is 1 mm to 300 mm. 7 . The method for producing yarns separated from the reinforcing fiber strands according to claim 1 , wherein the reinforcing fiber strands are widened by a widening jig before the process of intermittently separating the reinforcing fiber strands. 8 . The method for producing yarns separated from the reinforcing fiber strands according to claim 1 , wherein the concave-convex shape of the separating portion of the separating jig is concavity and convexity of the separated strands disposed in a width direction. 9 . A separating jig comprising: a separating portion having a concave-convex shape, wherein the following conditions of (1′) and (2) are satisfied, (1′) a height of a convex portion set in a range of 0.008 mm to 10,000 mm, and (2) curvature radius R of a distal end of the convex portion set to 0.01 mm to 50 mm.
