ABSTRACT<\/h2>\n\n\n\n

The Undyeing Swatch utilizes a combination of visible Light Emmiting Diodes \u0085LEDs) and photocatalytic nanoparticles to diminish the color of organically dyed textiles. As such, this swatch explores ‘undyeing’ as a design process that utilizes light and dye as materials for controlled interaction. The swatch itself consists of a knitted cotton I-cord coated with silver doped titanium dioxide nanoparticles \u0085(TiO2\/Ag) and dyed with hibiscus. The I-cord is used to encase a strand of LEDs and was then continuously woven into a swatch. When the LEDs are turned on, the light activates the nanoparticles which in turn break down organic matter (the dye). This swatch provides a proof of concept for the undyeing process, which I believe could be an interesting area of future exploration for HCI researchers and artists alike.<\/p>\n\n\n\n

MATERIALS<\/h2>\n\n\n\n

Size 5\/2 white 100% cotton yarn, size 7 double pointed knitting needles, USA Nanocoat multi- purpose LumaClean (i.e. TiO2\/Ag), Cylaplex meter long light emitting diode \u0085LED\u0088 string lights, and hibiscus tea.<\/p>\n\n\n\n

TOOLS & TECHNIQUES<\/h2>\n\n\n\n

Dyeing with natural dye (hibiscus), coating with aqueous nanoparticles, knitting \u0085I-cord), and continuous weaving where the same knitted I-cord is used in both the weft and warp directions.<\/p>\n\n\n\n
