ABSTRACT
The study was conducted at the Graduate School of Agriculture Faculty, Hokkaido University, Japan. 2017 to 2019 to Electrostatic fiber formation through dry-electrospining with optimum CA concentration is demonstrated in this study. Optimum CA concentration with minimize parameter could be reduced the cost as well as the time and also can serve a potential alternative materials from bio-based lignocellulosic biomass. The lignocellulosic biomass is most abundant materials over the world. Most of the lignocellulosic biomass consists of cellulose which the most interesting biopolymer which has different attractive properties can provide new sophisticated materials and technology in the current world. The objective of this study was to develop a new class CA dope concentration technique for suitable electrospining from biodegradable materials. There are different CAs are available in which Water Soluble Cellulose Acetate (WSCA) and Cellulose Di-acetate (CDA) were selected from both side. One is water soluble another one is water insoluble and solvent was selected according to the low environmental effect such as ethanol and acetone. Aqueous solvent was used to suppress the quick evaporation rate. Dope concentration was used 1% to 17%. Lower CA concentration produced became lower fiber diameter (0.81 µm) for WSCA and higher CA concentration higher fiber diameter (6.73 µm) for CDA. There is no fiber formation was observed from 1 to 5 % of CA concentration. Similar phenomena were occurring in both cases of CAs (WSCA and CDA). Finally, fine electrospun fibers were achieved from 11% (w/w) of WSCA and 9% (w/w) from CDA suspension.
