RESEARCH AND SCIENTIFIC TESTINGS
When we started our research about calotropis we didn't know what to expect since there was not enough research done on these fibers. After almost a year of extensive study and analysis of several test results, we are more than amazed about our new discoveries.
Hollowness of the fibers
Cross-section images in Scanning Electron Microscopy (SEM) done by SITRA show that both pod and stem fibers are hollow inside, which is similar to well-known alpaca wool protein fibers. On the other hand, calotropis fibers are made of cellulose which brings unique qualities to the fabric, thus earning the legendary name WEGANOOL™.
Tests on the fabrics showed positive results in stopping the growth of Staphylococcus (staph) bacteria. Although staph bacteria are not always pathogenic and can exist as members of the normal flora of the body, they are a common cause of several skin infections and a worldwide problem in clinical medicine.
Safe for extraction and human consumption
Our biggest concern was whether it would be safe to extract the fibers on a daily basis, and also if they are safe for use in clothing. During the extraction, we provide the necessary tools to ensure that the sap is not ingested by mistake. Cytotoxicity tests for both types of fabrics have given assurance that the fabrics are suitable for human usage.
