Type II Cellulose Fine Fiber Processing Without Chemical Defibration

The patent changes the fundamental parameter of the defibration approach from chemical to physical/mechanical methods. By using mechanical energy input (mixing, shearing) instead of chemical agents, the process achieves fiber diameter reduction without introducing chemical complexity or safety concerns. The physical defibration process maintains simplicity while achieving the desired fiber size reduction.

The patent replaces the chemical system with a mechanical system for defibration. Instead of using chemical agents to break down cellulose structures, the invention employs mechanical energy through mixing and shearing forces to achieve fiber separation and diameter reduction. This substitution eliminates the safety and environmental burden associated with chemical agents while maintaining the effectiveness of fiber size reduction.

The patent extracts and eliminates the chemical treatment steps from the defibration process. By removing the chemical agent addition, reaction, and removal steps, the process is simplified to focus on the essential mechanical defibration action. This extraction of unnecessary chemical steps reduces the total number of process steps while maintaining the ability to produce cellulose fine fibers effectively.
