<p>PURPOSE:To provide the titled polyester yarn exhibiting a flat peak at a specific wavelength, having a color tone and hue close to those of a dyed net and containing colorants of group A, group B and group C each exhibiting an absorption spectrum having a maximum absorption peak at respective specific wavelength. CONSTITUTION:The objective yarn exhibits an absorption spectrum having a flat peak within the wavelength range of 430-560mmu and an absorptivity range of 0.22-0.32 and contains (A) a group A colorant having a maximum absorption peak at 440-480mmu (e.g. brown colorant of perinone-type), (B) a group B colorant having a maximum absorption peak at 500-520mmu (e.g. red colorant of anthracene-type) and (C) a group C colorant having a maximum absorption peak at 540-560mmu (e.g. purple colorant of quinophthalone-type).</p> |
