Cellulose is extracted from natural fibers through retting, chemical treatments, or green solvents to remove non-cellulosic components. Nanocellulose is then produced via acid hydrolysis, mechanical fibrillation, or combined methods, with process parameters optimized for yield, crystallinity, and sustainability. Optimization focuses on balancing chemical concentrations, mechanical forces, and eco-friendly practices to achieve high-quality cellulose and nanocellulose.

Hello

In preparing cellulose from natural fiber:

1: which natural fiber? Tree or residual agriculture?

In nano cellulose:

1: mechanical process

2: ultrasonic process

The ultrasonic is better.
