Dust mite protection

Patients suffering from neurodermatitis, an inflammatory skin reaction most common among children, may be reacting to the same allergen that irritates people with respiratory issues—dust mite feces. Does a fabric labeled “house dust and dust mite barrier” protect people from both types of allergic reaction? Not necessarily, according to the Hohenstein Institute, Bönnigheim, Germany. Skin sensitive to dust mite allergens may also be sensitive to lots of other factors. Textiles worn by those with sensitive skin should use infection-preventing yarns that are not cytotoxic, preferably without mechanically irritating fibers, seams or accessories. The microclimate created in clothing is also important in preventing neurodermatitis; clothing should feature the right thermal conductivity, moisture absorption and breathability, for example. Hohenstein Institute has two accredited tests for manufacturers. “House dust and dust mite barrier” is a designation that keeps dust mite excrement away from textile users. “Effective against dust mites” is a designation that goes further—it signifies that the treated textile actually inhibits the growth of dust mites, or even destroys them. Manufacturers marketing products beneficial to sufferers of both respiratory reactions and skin irritation in response to dust mites may want to know—and label—a textile’s properties accordingly.
