Cellular Debris in the Grease of Wool Fibers

The study investigated cellular debris in wool grease using transmission electron microscopy. It found that cellular debris from the wool follicle, its appendages, and the epidermis was dispersed in wool grease. The debris showed little interaction with undamaged wool fiber surfaces but adhered to damaged fiber surfaces. Additionally, a negative correlation was observed between the protein content of wool washings and the clean wool yield, suggesting that higher protein contamination in wool washings resulted in lower clean wool yield.
