Abstract
A process is provided for identifying a production and/or commercial history of a silk fiber or a product made therefrom.
Claims20
A process for marking silk manufactured from silkworms with an XRF-identifiable marker, the process comprising:
- feeding silkworms with leaves treated with a formulation comprising at least one XRF-identifiable marker or feeding silkworms with a feeding composition enriched with a formulation comprising at least one first XRF-identifiable marker under conditions permitting said marker to be taken up by the silkworms, and/or
- treating a bave with a formulation comprising at least one XRF-identifiable marker, during the bave treatment stage, and/or
- treating a cocoon with a formulation comprising at least one XRF-identifiable marker, and/or
- treating a silk fiber during a degumming stage or during an ennobling stage to thereby mark the bave, the cocoon, and/or the silk fiber with the at least one marker, wherein the XRF-identifiable marker is not a native material to a silk fiber or silk manufacturing process.
A process for identifying a production or commercial history of a silk product, the process comprising
- feeding silkworms or treating a silkworm cocoon or a silk fiber produced therefrom with a formulation comprising a first XRF-identifiable marker at a first stage, to embed said first marker in the silk fiber or bave;
- treating the silk fiber at a second stage with a second XRF-identifiable marker to embed said second marker in the silk fiber;
- and
- analyzing the presence of the first and second XRF-identifiable markers in said silk fiber or product made therefrom to thereby identify the production or commercial history of the silk fiber.
A fibroin rich silk fiber produced from a silk-producing animal, the fiber being associated, embedded or adsorbed with at least one XRF-identifiable marker.
A system for managing a supply chain of silk and silk products, the system comprising a database system (central or distributed) comprising data relating to silk and their marking with an XRF-identifiable marker.
A process for identifying a production and/or commercial history of a silk fiber or a product made therefrom, the fiber or product having been marked with at least one XRF-identifiable marker, the process comprising directing an X-ray or Gamma-ray radiation towards the fiber or product made therefrom and detecting a response X-ray signal emitted from the marker in response, such that said response signal is indicative of presence, concentration or relative concentration of the marker to thereby provide information encoded by the marker on the production or commercial history of the silk fiber or product made therefrom.
