Cellulose and Pectic Polysaccharides

Cellulose and Pectic Polysaccharides

Every plant cell has a cell wall that protects the cell, provides structural support, and gives the cell shape. Cellulose, the main structural component of the plant cell wall, makes up over 30% of plant matter. It is the most abundant organic compound on earth. Cellulose is an unbranched polysaccharide composed of linear chains of glucose molecules linked by β (1→4) glycosidic bonds.
As a cell matures, its cell wall specializes according to its type. For example, the...

Background:

All-cellulose composites (ACCs) are promising renewable and biodegradable materials.
Current ACC research primarily focuses on films and bulk forms, limiting applications.
Petroleum-based synthetic polymers face environmental concerns.

Purpose of the Study:

To develop a simple, efficient, and scalable welding method for all-cellulose composite (ACC) yarns.
To investigate the properties of ACC yarns produced via this novel welding technique.
To establish a green manufacturing route for high-performance bio-based yarns.

Main Methods:

Welding of cellulose yarns by partial dissolution and regeneration using phosphoric acid.
Characterization of the in-situ core-shell structure of the welded ACC yarns.
Optimization of regeneration and drying procedures to enhance yarn strength.

Main Results:

The developed welding method yields green, self-reinforced ACC yarns.
Welded yarns exhibit improved strength (134.6 MPa), friction resistance (8000 cycles), moisture regain (11.89%), and dyeing properties.
Optimized procedures further increased yarn strength to 190.5 MPa.

Conclusions:

The phosphoric acid-based welding method is a straightforward and scalable approach for ACC yarn production.
This technique offers a sustainable route to high-performance bio-based yarns.
The enhanced properties of ACC yarns open possibilities for replacing synthetic materials in various applications.
