The development and successful testing of a method for unreeling the strands of silk in wild silkworm cocoons could clear the way for establishment of new silk industries not only in Asia but also in vast areas of Africa and South America. The report appears in ACS’ journal Biomacromolecules.
The group found that the surfaces of wild cocoons were coated with a mineral layer and that removing this layer (“demineralizing”) made it easy to unreel the cocoons into long continuous strands with commercial reeling equipment. These strands were just as long and strong as those from Mulberry silkworm cocoons. The researchers say that the new method could expand the silk industry to new areas of the world where wild silkworms thrive.
