Superfine wool yarn and manufacturing method thereof

Abstract

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.

Description

technical field [0001] The invention relates to a wool yarn and a production method thereof. Background technique [0002] Thin wool fabrics and fabrics are spun from ultrafine wool fibers into ultrafine wool yarns and then woven. They are delicate, soft, considerate and comfortable. High-grade wool fabric products favored by the market and consumers. However, the problem existing in the existing ultra-fine wool yarn spinning process is that since the spinning of ultra-high-count wool yarn requires fine wool fibers, the number of spun yarn cross-sections is not less than 36, and the cost of raw materials is high, while ultra-fine wool is scarce and natural. Resources, the market is in short supply, thus limiting the development of a large number of products. If wool with thicker fibers is used, there will be many details in the spinning process, and the ends will be easily broken. In addition, the cohesion of mercerized wool fibers is poor, and the yarn is prone to pilling...

However, the problem existing in the existing ultra-fine wool yarn spinning process is that since the spinning of ultra-high-count wool yarn requires fine wool fibers, the number of spun yarn cross-sections is not less than 36, and the cost of raw materials is high, while ultra-fine wool is scarce and natural. Resources, the market is in short supply, thus limiting the development of a large number of products

If wool with thick fibers is used, there will be too many fine details in spinning, and the cohesion of mercerized wool fibers is poor, and the yarn is prone to pilling, which affects product quality and yield
