Abstract
Disclosed is a fluorescent elastic yarn and method for producing the same. The fluorescent elastic yarn can fluoresce sufficiently to allow a thin elastic yarn to be seen by the naked eye when ultraviolet light is irradiated to the fluorescent elastic yarn by adding a novel organic additive to a polymer or a spinfinish. Therefore, the fluorescent elastic yarn of the present invention is advantageous in that production of inferior covered yarns is prevented.
Claims9
A fluorescent elastic yarn comprising 0.001 to 20 wt % of a fluorescent brightener.
A method for producing a fluorescent elastic yarn comprising the step of spinning a polyurethane-urea copolymer,
- wherein a fluorescent brightener is mixed with the polyurethane-urea copolymer in an amount of 0.001 to 20 wt %.
A method for producing a fluorescent elastic yarn comprising the step of spinning a polyurethane-urea copolymer,
- wherein a spinfinish having a fluorescent brightener dispersed therein is applied to a spun elastic yarn in such an amount that a content of the fluorescent brightener in the resulting elastic yarn ranges from 0.001 to 20 wt %.
