Questions about oligomer-induced dye defects are quite common, severely affecting product quality and causing contamination to equipment that is difficult to clean. Here's a summary of the issues:

Oligomers, also known as polycondensates, oligopolymers, or short polymers, are low molecular weight substances with the same chemical structure as polyester fibers, found within the fibers themselves. They are a byproduct of the polyester spinning process. Typically, polyester contains 1% to 3% of oligomers. Oligomers are polymers composed of fewer repeating units and have a relative molecular weight that falls between that of small molecules and large molecules.

The term "oligomer" is derived from the Greek prefix "oligo," meaning "some." Most polyester oligomers are cyclic compounds formed by three ethyl terephthalate units.
