CROSS-LINKED ACRYLATE-BASED FIBER DYEABLE BY REACTIVE DYE, FIBER STRUCTURE AND METHOD FOR PRODUCING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a cross-linked acrylate-based fiber dyeable by a reactive dye, and having excellent moisture-absorbing and releasing properties, antibacterial properties, deodorant properties and color fastness to wet friction, and to provide a fiber structure containing the cross-linked acrylate-based fiber dyeable by the reactive dye, and a method for producing them.;SOLUTION: The cross-linked acrylate-based fiber dyeable by the reactive dye has ≥20 wt.% saturated moisture absorption at 20°C in 65% RH, and ≥3 grade color fastness to the wet friction. The fiber structure contains ≥3% cross-linked acrylate-based fiber dyeable by the reactive dye, and has ≥5 wt.% saturated moisture absorption at 20°C in 65% RH, and ≥3 grade color fastness to the wet friction. The fiber and the fiber structure maintain the excellent characteristics of a conventional cross-linked acrylate-based fiber and a fiber structure of the cross-linked acrylate-based fiber such as the moisture-absorbing and releasing properties, and enable the dyeing by the reactive dye which is impossible in the conventional fiber. The fiber and the fiber structure have excellent color fastness to the wet friction and are suitably used in a field requiring the dyeing.;COPYRIGHT: (C)2004,JPO
