Kind Code:
B2
Abstract:
To provide a polyester fiber which exhibits high crimping properties after alkali weight loss and is excellent in any of soft texture, deep-dyeing properties, drape properties, and worsted tone when used as a fabric.SOLUTION: The latently crimped deep-dyeing polyester fiber as composite yarn comprises a polyester resin composition A containing a polyester resin A and product particles derived from a phosphorus compound and an alkaline earth metal compound or product particles derived from a phosphorus compound and an alkali metal compound and an alkaline earth metal compound; and a polyester resin composition B containing a polyester resin B having an intrinsic viscosity higher than that of the polyester resin A and inorganic particles having a high specific gravity. The composite shape of the polyester resin composition A and the polyester resin composition B is a side-by-side type or an eccentric core-sheath type. The content of the inorganic particles having a high specific gravity in the polyester resin composition B is 0.1 mass% or more. The crimp rate after the boiling water treatment is 40% or more.SELECTED DRAWING: Figure 1
