The application discloses a
processing technology and cocoon silk, and
processing is performed according to the following steps: S1: swelling dispersion and anti-sticking treatment: placing silk containing
sericin in a weak acid buffer prepared from an
organic acid, the pH value being 1.0-4.0, and performing swelling treatment by heating,
unsaturated fatty acid is added in the weak acid buffer in advance or is added in the initial stage of swelling in step S1, S2: post-treatment: taking out the swelled silk and
drying, and performing
drying to obtain dispersed single-
fiber cocoon silk which does not adhere to each other. Through the two-step cooperation of 'pH-temperature dominant swelling' and '
oleic acid preventing secondary adhesion', the prepared cocoon silk retains 60%-90% of natural
sericin and is in a fluffy and dispersed single-
fiber state; the cocoon silk replaces the traditional degumming process, reduces
pollution, has high spinnability, and the retained
sericin has excellent
biological activity and
biocompatibility, so that the cocoon silk material has higher competitiveness and can become a
raw material of biomedical textiles.
