Beschreibung
Zusammenfassung:	PURPOSE:The titled polyester sheath-core type conjugate fiber in which the core polymer is colored but the sheath polymer is not and the share of the sheath component is specified, thus giving mohair-like touch in low costs. CONSTITUTION:A polymer containing a pigment dispersed therein such as polyethylene terephthalate is used as the core component and another polymer, preferably containing less than 0.2wt% particles such as titanium oxide is used as the sheath component to effect conjugate spinning by means of a concentric sheath-core spinning device. Then, the resultant yarn is drawn to give the objective fiber in which the core is colored in pale yellow to pale brown with a b- value of 5-15, the sheath is not colored and the share of the sheath polymer is 10-50wt%.
