How do you harvest the silk for your Natural Silk Floss?

Jun 30, 2015

Our Natural Biodegradable Silk Floss is sourced in cooperation with the CORSEDA Farm Cooperative in Cauca, Colombia. The CORSEDA Cooperative is a family owned and operated initiative that focuses on redirecting worthy sources of livelihood back to the native populations of Colombia in a sustainable and enriching manner. Spun by hand, the silk we use is pure, natural silk thread that is a 100% biodegradable material and comes from silk worms. Silk is used to make clothes, floss and many other products throughout the world.  Silk thread is one of nature’s strongest natural fibers and the only natural fiber strong enough to be made into floss. In order to harvest in an efficient, effective, and safe manner, the silk cocoons are boiled to allow the whole cocoon to be unraveled as one continuous thread, permitting a much stronger thread and reducing the number of cocoons needed to make viable silk thread. The result is a 100% natural product that can biodegrade and causes no impact on the environment after use. We here at RADIUS believe this is a very important offering for our consumers and our environment. For consumers who are looking for a vegan option, we do also offer Vegan Mint and Vegan Cranberry flosses which are made from nylon rather than pure silk.
