Abstract:
     A silk extract gel or spongy silk extract gel with chemical cross-linking structure is prepared from cocoon shell through refining in aqueous solution of Na2CO3, washing with distilled water, and drying to obtain silk extract fibres, dissolving in aqueous solution of CaCl2, dialyzing with cellulose dialysis membrane in flowing water, removing CaCl2, concentrating, regualting pH value, mixing with epoxy compound as cross-linking agent, laying aside for solidification to obtain the gel, immersing in distilled water, and removing unreacted substance. It has high compressive strength (greater than 100 g/sq.m) and high compression deforming rate (greater than or equal to 60%).
