Microstructural Characteristics of Eri Silk Fibre in Different Layers of Cocoon

Five layers, i.e. floss, upper, middle, lower and pelade, exist in cocoon shell from outer to inner portion. An attempt has been made for assessment of microstructural characteristics eri silk fiber different layers cocoons. Wide angle x- ray diffraction revealed increase crystallinity as well degree orientation decrease crystal size besides lattice spacing remains at par floss pelade layers. So, there is an improvement single fibre tenacity initial modulus position cocoon’s shell.
