Abstract For the application of Jeju scoria scattered around the island as a natural dye, cotton fabrics were dyed with the dye
and their properties were measured including dyeability, colorfastness, antibacterial activity, deodorization efficiency, ultraviolet
protection, and far-infrared emission. The dyed cotton fabrics were in yellowish red and optimal dyeing conditions were obtained
with a colorant concentration of 25%(o.w.b) at a temperature of 80 for the dyeing time of 120 minutes. The ratings of
colorfastness to light, rubbing, perspiration, and washing were 8, 5, 5, and 4~5 respectively. After 15 wash cycles, colorfastness
remained as much as 4~5 rating. The cotton fabric dyed with Jeju scoria demonstrated excellent antimicrobial activity and
deodorization efficiency of 99.9% and 93.9% respectively. Ultraviolet protection factor was 50+. Far-infrared emission rate and
far-infrared emission intensity were 90% and 362(W/) respectively. The Jeju scoria can be introduced as a new colorant for
the natural dyeing of cotton. |
