Abstract
The present invention relates to a regenerated cellulosic fiber which contains an incorporated dye pigment and a fluorescent dye applied by overdying, the use of this fiber for the production of yarns and fabrics and a process for the production of these fibers. This fiber satisfies the demands of EN 471 in relation to luminance factor, the chromaticity coordinates and color fastness and possesses a light fastness (ISO 105-B02, process 2) of more than 5.

-12. (canceled)
A cellulosic regenerated fiber, comprising a spun-in pigment and a fluorescent dye applied by overdyeing, and having a lightfastness greater than 5, measured according to ISO 105-B02, Method 2.
The cellulosic regenerated fiber as claimed in claim 1, which is produced using a viscose, modal or lyocell process.
The cellulosic regenerated fiber as claimed in claim 1, further comprising a flame retardant.
The cellulosic regenerated fiber as claimed in claim 3, wherein the flame retardant is a spun-in organophosphorus compound (preferably 2,2′-oxybis[5,5-dimethyl-1,3,2-dioxaphosphorinane]2,2′disulfide).
The cellulosic regenerated fiber as claimed in claim 1, further comprising one or several antibacterial agents.
A use of the fibers as claimed in claims 1 to 5 for the production of a yarn.
A use of the fibers as claimed in claims 1 to 5 for the production of a fabric.
