    摘要： Disclosed is a fiber made of a polyester resin, wherein the polyester resin is a copolymer including a dicarboxylic acid component and a glycol component; of the dicarboxylic acid component, 80 mol % or more is accounted for by a terephthalic acid component, 4.0 to 12.0 mol % is accounted for by a cyclohexane dicarboxylic acid component, and 2.0 to 8.0 mol % is accounted for by an adipic acid component; and the glycol component contains an ethylene glycol component as a main component thereof. A polyester fiber is thereby provided which can be dyed with excellent deep color property and fastness property in dyeing under a normal pressure environment and which can offer stable quality and processing performance also by a direct spinning stretching method or other general melt-spinning methods.

    摘要： A fiber made of a polyester copolymer (B), wherein the polyester copolymer (B) comprises a dicarboxylic acid component and a glycol component, and the dicarboxylic acid component comprises 75 mol % or more of a terephthalic acid component, 1.0 mol % to 3.5 mol % of component (a) derived from a compound represented by formula (I), 2.0 mol % to 10.0 mol % of a cyclohexane dicarboxylic acid component (b), and 2.0 mol % to 8.0 mol % of an aliphatic dicarboxylic acid component (c). This can afford a polyester fiber that exhibits deep color property to cation dyes and disperse dyes under a normal pressure environment and is superior in color fastness to washing and color fastness to light and can secure good spinnability.
