Dyed loess and charcoal fabrics are sold in market as bedding. They have a lot of functions so that people are getting to increase their expenditure for them. Thus we investigated a repellent effect of loess fabrics and charcoal fabrics against house dust mites. The evaluation of the repellent effect of dyed loess fabrics and charcoal fabrics was conducted by using Dermatophagoides farinae and D. pteronyssinus. We compared the repellent effect of dyed loess fabrics at different doses of 0.3, 1.0, 3.2, 10.0 ㎎/㎠ and dyed charcoal fabrics at different doses of 0.3, 0.6, 1.0 ㎎/㎠. Commercial loess fabrics did not have a repellent effect against house dust mites. but commercial charcoal fabrics had the repellent effect by 78% against them. In case of dyed charcoal fabrics added with charcoal powder over 0.6 ㎎/㎠, they showed the repellent effect by over 80%. These results suggest that loess fabrics and charcoal fabrics have a repellent effect of against house dust mites and they can be commercially used for the purpose.
