On the Methods of Prevention of Silｋ from Browning

摘要

The degummed silk has a tendency to browning. This comes from the active character of amino and hydroxyl groups in the fibre. Hence it can be considered that the browning may be prevented by the locking of these groups or the isolation of fibre from air and moisture. On this object we have examied acetylation, formation and resin finishing as such treatment for silkfibre. The result were not so satisfactory.
