SUMMARY:

The growing concern over the environmental impacts generated by the textile industry has driven the search for sustainable alternatives in fiber and staple yarns production. In this context, the present dissertation proposes the study of canine wool—a byproduct typically discarded during animal care—as an alternative and environmentally viable raw material for the manufacture of textile filaments. This work investigates the feasibility of incorporating canine wool into blends with synthetic fibers (polyester and acrylic) and natural fibers (cotton) at varying proportions (30%, 50%, and 70%), with the aim of analyzing the physical, mechanical, thermal, and aesthetic properties of the resulting filaments. The adopted methodology included the collection and hygienization of canine wool, followed by its spinning in different blend compositions combined with each type of fiber, yielding a total of nine distinct formulations. The samples were subjected to standardized laboratory tests, focusing on tensile strength and elongation measurements performed on a dynamometer in accordance with textile technical standards. The results demonstrated that staple yarns containing up to 50% canine wool exhibited good mechanical strength, maintaining satisfactory levels of elongation and structural integrity, particularly in blends with polyester. When the canine wool content reached 70%, a slight decrease in tensile strength was observed, although elasticity remained within acceptable levels for use in light apparel and accessories. It was noted that the yarns composed of cotton (CO) and canine wool (DW) were not linear; their structure exhibited exposed surface fibers that appeared loose. Consequently, regions with thickened spots were more pronounced in the blends containing 50% and 30% canine wool. Overall, the findings indicate that canine wool possesses characteristics comparable to conventional animal fibers, and its utilization can help reduce environmental impacts while adding value to urban waste.
