Clothing/textile technologists work on the design, development, and production of fibers, yarns, and textiles. They carry out technical and quality control work to ensure products meet specifications. Technologists develop manmade fibers, spin fibers into yarn, weave or knit yarn into fabrics, oversee dyeing and finishing processes, and ensure quality in areas like strength and colorfastness. Some specialize in research and product development, undertaking research to find new ways of using yarns or developing chemicals to improve fabric properties.
