| Abstract: | The processes of fiber formation by the fibroin of natural silk have been studied by the methods of birefringence in a longitudinal hydrodynamic field and optical rotatory dispersion. The experiments were performed with the direct drawing of a fiber from the secretion of the silk glands of the silkwormBombyx mori. The position of appearance of a longitudinal hydrodynamic field within the gland has been detected and experimental results have been obtained which permit an evaluation of the critical condition for the  - structural transition of the fibroin chains.Institute of the Chemistry and Physics of Polymers, Academy of Sciences of the Republic of Uzbekistan, Tashkent, fax (3712) 44 26 61.
