<P>PROBLEM TO BE SOLVED: To provide a knot structure having knots hardly loosened and having excellent strength. <P>SOLUTION: In a knot structure, the knot is formed at an end 2 of a fiber structure including a high-melting point polymer and a low-melting point polymer, and having a surface where the low-melting point polymer is exposed. The low-melting point polymer is melted and solidified after the knot is formed, so that the knot retains the form of a loop portion 1. <P>COPYRIGHT: (C)2012,JPO&INPIT |
