Description

Diethylene glycol diacetate is a coagulating agent that is used in the production of polyester fibers. It reacts with fatty acids and forms ester compounds, which are then polymerized and cross-linked to form a film. The acetylation of the hydroxyl group on the molecule provides an additional degree of polymerization, thereby increasing the molecular weight of the product. The reaction vessel used for this process is typically heated at a temperature between 180°C and 220°C to promote polymerization. This polymer film can be made into filaments by extruding it through a spinnerette or die head. The filament may be cut into small particles before being placed in a section, which is then processed as desired.
