Advances in wool spinning technology

Enhancing Strength of Wool Fiber Using a Soy Flour Sugar-Based “Green” Cross-linker

“…3 The cleaned dry wool is commonly processed through a carding machine and comber to produce a continuous web or sliver (wool top) with individual fibers parallel to each other. 4 The length of fibers in the sliver can vary from 2 to 6 in. depending on the wool variety and the processes used.…”

“…Sliver is drawn to the desired linear density and twisted during spinning to form continuous yarn. 4 Since wool fibers are inherently weak, fiber breakage during spinning and weaving processes, which are commonly carried out under tension, is a significant problem. Fiber breakages reduce the production efficiency, create fabric defects, and generate significant amounts of fiber and fabric wastes.…”

“…The fleece (raw wool) obtained from the animals contains 30–70% impurities, such as sand, dirt, grease, dried sweat, etc., most of which are removed through the scouring process . The cleaned dry wool is commonly processed through a carding machine and comber to produce a continuous web or sliver (wool top) with individual fibers parallel to each other .

“…Since wool fibers are inherently weak, fiber breakage during spinning and weaving processes, which are commonly carried out under tension, is a significant problem. Fiber breakages reduce the production efficiency, create fabric defects, and generate significant amounts of fiber and fabric wastes . Increasing the strength of the fibers can not only solve these issues but also allow spinning finer yarns from the same fibers, significantly increasing their value.…”
