  Abstract

Silk has been extensively studied as a promising material for biomedical and cosmetic applications due to its excellent biocompatibility, cytocompatibility, biodegradability, among other unique properties. In addition to these properties, the natural silk nonwoven fabric has attracted attention from researchers in bio-related fields due to its ease of fabrication. The natural silk nonwoven fabric is prepared by reeling silkworm cocoons and subjecting them to heat treatment. In this study, various silkworm variety cocoons were wet- and heat-treated and then, their whiteness index and crystallinity index were measured to gain a better understanding of structural characteristics of cocoons. The whiteness index was significantly reduced above 200 °C and the extent of reduction varied slightly depending on the silkworm variety. Wet treatment of the silkworm cocoons prevented slightly the decrease in the whiteness index of cocoons. The crystallinity index of cocoon was different depending on the silkworm variety and Baekokjam cocoon showed the highest crystallinity index. Outside of cocoon showed a remarkable decrease of crystallinity index above a treatment temperature of 200 °C. However, the crystallinity index of outside of cocoon did not decrease when the wet treatment was conducted prior to heat treatment. On the other hand, the crystallinity index of inside of cocoon increased above 200 °C regardless of wet treatment.
