Superfine wool yarn and manufacturing method thereof

The invention discloses a superfine wool yarn and a manufacturing method thereof. The superfine wool yarn comprises 100-120Nm/2 of yarn counts, 1050-1200t/m of single twist with a twist direction of Z and 480-550t/m of plied twist with a twist direction of S. The manufacturing method comprises the process steps of wool top recombing, primary silver mixing, secondary silver mixing, quartic gilling, triple roving, spun yarn, spooling, doubling, two-for-one twisting, reeling silk, checking and the like. In the invention, raw materials of the superfine wool are selected, and the reasonable yarn counts and the twist are determined at the same time. By adopting some special measures on the spinning process and optimizing the technological parameters, the excellent and low-consumption superfine wool yarn with the yarn counts of 120Nm/2, and the yarn levelness of less than 15 percent and anti-pilling of more than or equal to the third level is successfully manufactured; and the number of the cross-section fibers of the fine yarn is only 28, which is far lower than the limit of the number of 36 in the international standard. The invention not only provides a new yarn product with excellent quality and high cost performance, but also provides a beneficial spinning method for sufficiently utilizing and reasonably developing tight wool resources.
