Beschreibung
Zusammenfassung:	PURPOSE:The titled fibers for colored polyester fibrous structures, e.g. nonwoven fabrics, consisting of a polyester having a low softening point as a sheath component and polyester given the same color as the main fibers with a high softening point as a core component and having improved adhesive properties without whitening of ground color, etc. CONSTITUTION:Fibers, obtained by joining (A) a polyester having 90-210 deg.C softening point, preferably polyester, having 100-190 deg.C softening point and produced from terephthalic acid and ethylene glycol as a sheath component to (B) a polyester given the same color as the main polyester fibers of a fibrous structure with >=240 deg.C softening point, preferably copolyester produced from terephthalic acid, isophthalic acid and ethylene glycol as a core component at 30/70-70/30 weight ratio of the sheath component to the core component, consisting essentially of the colored polyesters having >=240 deg.C softening point and useful for fibrous structures.
