How / why is silk hypoallergenic?
Silk’s hypoallergenic properties stem from a number of features. First, silk starts out simple and clean – merely a strand of natural fiber and held together with a natural glue called sericin. Second, sericin is a natural repellant that is inhospitable to dust mites, a major source of allergens. Third, silk is processed with little or no chemicals. Finally, silk maintains its structure for a very long time, unlike down which can degrade and fall apart, creating tiny pieces that can cause irritations.
