Summary
The existing methods of silkworm cocoon treatment, including heat, chemicals, and vacuum, essentially damage the silk thread and considerably decrease the yield of raw silk as compared with untreated cocoons. A possibility of treating the silkworm chrysalis by Co/sup 60/ gamma rays was studied in this connection. A comparative study of the properties of the silk thread obtained by this method was made. The nature of radiation effecta of y rays on the substance of the silk thread was investigated. While the cocoons treated in vacuum decompose when stored, the irradiated cocoons are preserved well in storage for many months, additional preservation being unnecessary. Moreover, gamma rays have a beneficial effect on the thread properties. The unwinding of the cocoons becomes much easier, and the return and break coefficients become lower. Such properties of the cocoon shell as swelling and water permeability improve as well. The knitting property of the irradiated cocoon thread is better than that of the thread of the heat-treated cocoons or of the raw cocoons. (C.H.)
