Cellulose acetate fibers prepared from different raw materials with rapid synthesis method

Area of Science:

• Polymer Chemistry
• Materials Science
• Textile Engineering

Background:

• Traditional cellulose acetate (CA) preparation involves harsh conditions.
• Transesterification offers a milder alternative for cellulose modification.

Purpose of the Study:

• To develop and evaluate a simple, rapid transesterification method for producing CA fibers.
• To investigate the influence of cellulose raw material properties on CA characteristics.

Main Methods:

• Six different cellulose raw materials were subjected to transesterification.
• Cellulose acetate (CA) solutions were concentrated via vacuum distillation to form spinning dopes.
• Characterization included XRD, FT-IR, and NMR (1H, 13C, HSQC).

Main Results:

• Successful esterification of all cellulose sources within 15 minutes.
• Confirmation of CA synthesis through spectroscopic analysis.
• Degree of substitution (DS) was linked to cellulose degree of polymerization (DP).

Conclusions:

• The transesterification method is efficient for CA fiber production.
• Cellulose DP is a critical factor affecting CA properties and fiber performance.
• This method provides a viable route to tailor CA fiber characteristics.
