<p>PURPOSE: To obtain an untwisting material capable of surely preventing thread from moving right and left. CONSTITUTION: This untwisting material is obtained by connecting one of two ring materials 2 and 3 for linking threads each comprising two yarns to the other in its ratable state. Curved materials 6 and 7 in which outside edges 6a and 7a are curved inside between right and left side materials 4a/4b and 5a/5b constituting the ring materials 2 and 3 and inner edges 6b and 7b are curved outward are hung. Intervals L1 between the right and left side materials 4a/4b and 5a/5b is set as the interval L1 at which the thread 1 comprising two yarns is arranged just without a gap. When the thread comprising the two yarns is arranged in the curved materials 6 and 7, the degree of curve of the outside ends 6a and 7a of the curved materials 6 and 7 and the positions of the curved materials 6 and 7 against the side materials 4a/4b and 5a/5b are set as a degree of a curve and positions in which half or more of the thread 1 comprising the two yarns is not projected from the end pars of the side materials 4a/4b and 5a/5b to the outside.</p> |
