Abstract
The application relates to a method of obtaining silk feedstock solution from a gland of a silkworm or another silk-producing arthropod in which the body of the silkworm or the other silk-producing arthropod is cut open and the gland removed. The silk feedstock solution is subsequently extracted from the gland and used for extrusion, spinning or moulding of objects.
Claims14
A method of obtaining silk feedstock solution from a gland of a silkworm or another silk-producing arthropod, wherein the gland has an epithelial layer, comprising:
- a first step of cutting open a body of the silkworm or the other silk-producing arthropod;
- a second step of removing the gland from the body;
- a third step of removing the epithelial layer;
- and
- a fourth step of extracting the silk feedstock solution from the gland.
A method of obtaining silk feedstock solution from a gland of a silkworm or another silk-producing arthropod, comprising:
- a first step of cutting open a body of the silkworm or other silk-producing arthropod;
- a second step of removing the gland;
- and a third step of extracting the silk feedstock solution from the gland, in which the silk feedstock solution is treated with a cross-linking agent.
A silk feedstock solution in pure and isolated form, as directly isolated from a gland of a silkworm or other silk-producing arthropod, wherein the gland has an epithelial layer, by:
- a first step of cutting open a body of the silkworm or the other silk-producing arthropod;
- a second step of removing the gland from the body;
- a third step of removing the epithelial layer;
- and
- a fourth step of extracting the silk feedstock solution from the gland.
