Figure 2 (b), cylindrical fibers are observed with diameters of 13 +/- 7 [micron]m, randomly oriented composite fibroin, because the thermal process degummed at 60[grados]C removes the sericin coating; morphology and reduction in the value of the average fiber diameter are evidence of correct degumming.
They boiled the cocoons in a solution of sodium carbonate to separate a protein called fibroin, which is the one they want, from one called sericin, which they do not.
Sericin hides the brightness and whiteness of the silk as well as causing it to have a hard handle.
It contains about 75% actual fibre fibrion and 25% of sericin gummy protein that holds filaments.
6) The removing process of exposed sericin at the surface of silk which is twisted of original yarn.
There is some scientific evidence dating back almost 20 years that may explain the benefits of silk on the skin: Swiss scientists published research in the Cosmetics and Toiletries Journal to show that sericin, the protein in silk, can adhere to the keratin (protein) in skin and hair resulting in a perceptible "homogeneous protective film".
These glands also produce another protein, sericin, that glues the two threads together as the silk hardens in the air.
To form the devices, Tufts scientists boiled cocoons of the Bombyx mori silkworm in a water solution and extracted the glue-like sericin proteins.
The silkworm encases its two main silk proteins in a coat of sericin, a gluelike protein that seals the cocoon together, when used as sutures or for other medical applications, this sericin glue can provoke an immune response in people and therefore must be coated over or removed.
The boiling water softened the sticky protein called sericin that held the fibers together.
