What is the structure of cellulose acetate tow

Vertical form
The longitudinal surface of acetate fiber is smooth with obvious grooves. This morphology enables better control of the structure and properties of fibers during the spinning process.

Cross-sectional shape
The cross-section of acetate fiber is in the shape of alfalfa leaves, with a relatively smooth periphery, few shallow serrations, and no skin core structure. This cross-sectional shape has a significant impact on the mechanical and filtration properties of fibers.
