SYNTHETIC FIBER MULTIFILAMENT HAVING MULTIPLE COLOR

摘要

PURPOSE:To obtain a synthetic fiber multifilament dyed in multiple colors using only one kind of polymer and to obtain differently dyed minute parts randomly dispersed in a completely unreproducible manner, by constituting the synthetic fiber multifilament having multiple colors with specific monofilaments. CONSTITUTION:A synthetic fiber multifilament having multiple colors is composed of multiple single filaments y1-y10. Each single filament contains the parts (u) having different color and shown by dots. The parts (u) are randomly and longitudinally distributed in the matrix (n) having the intrinsic color of the polymer shown by the white background. Each single filament y1-y10 contains randomly distributed parts (u) having different color in its cross-section. The part (u) having different color in each single filament y1-y10 is essentially different between the single filaments y1-y10 in the cross-section of a synthetic fiber multifilament containing the part having different color.
