COLOR DEEPENING AGENT FOR HYDROPHOBIC FIBER, COLOR DEEPENING METHOD USING THE SAME AND DYED HYDROPHOBIC FIBER TREATED WITH THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a method for obtaining a dyed hydrophobic fiber having water absorption properties and a deep color by deepening the color of a hydrophobic fiber or a dyed hydrophobic fiber-containing fiber.;SOLUTION: The dyed hydrophobic fiber having a deep color and water absorption properties is obtained by treating a dyed hydrophobic fiber with a color deepening agent containing silica fine particle treated with an amino group-containing silane coupling agent under an acidic condition and a polyether-modified polysiloxane.;COPYRIGHT: (C)2006,JPO&NCIPI
