ABSTRACT:
A process for producing non-woven silk fiber fabrics comprises the following steps: a) obtaining silk fibroin, for example either from silk cocoons, or silk textiles or waste silk; b) removing the sericin layer covering the silk fibroin fibers, when present; c) breaking the disulfide bonds between heavy (350 kDa) and light (27 kDa) chains of silk fibroin in order to obtain the production of chain fragments which serve as a specific cellular recognition sites promoting the attachment and growth of cells, d) homogenising of the material resulting from step c).
