The influence of ammonia gas treatment of silk fiber on its destruction was investigated to observe the change of the surface structure and its physical properties.
Silk fibroins were treated in textural form with ammonia gas for the different length of time (5-10 days), and then their surface structure was observed by means of the the electron microscope.
The action of ammonia gas treatment as the gas phase method was found to be partial and also slight.
While swelling and contraction of the surface, the coloring and destruction of silk fiber was noted. This tendency is similar to that in an alkali treatment (0.1 N NaOH solution).
