Abstract
The invention discloses a blended yarn of wool and ramie and a manufacturing method thereof. The manufacturing method uses the following raw materials for the blended yarn in the following weight ratio: 30 - 70% of wool fiber with the main length between 70 and 80 mm, and 70 - 30% of ramie fiber with the main length between 120 and 130 mm. The manufacturing method adopts a process flow as follows: cutting the ramie fiber to the main length of the wool fiber, adding wool lubricating oil to the wool fiber and finishing the wool fiber, then blending the ramie fiber and the wool fiber, and obtaining the blended yarn of wool and ramie through processing steps of loosening, carding, joining, roving, spinning, twisting and winding. The wool lubricating oil accounts for 0.8 to 1% of the weight of the raw materials. The wool lubricating oil is sprayed on each layer of wool fiber. After the finishing, the fiber is covered for standing for 24 to 36 hours. A wool type roller carder is used for carding. A roving frame and a spinning frame are both wool type spinning devices. The rotation speed of a cylinder of the carder is between 580 and 620 r/min; the rotation speed of a flyer of the roving frame is between 350 and 450 r/min; the doffing speed of the flyer is between 250 and 350 r/min; and the flyer speed of the spinning frame is between 10500 and 11500 r/min. Through blending of the wool fiber and the ramie fiber, the blended yarn with good performance is obtained.
Description
Technical field [0001] The invention belongs to the textile field, and specifically relates to a blended yarn of wool and ramie and a manufacturing method thereof. Background technique [0002] There are many types of yarns on the market. With the improvement of processing technology and the improvement of people's living standards and consumption levels, a single natural fiber yarn is far from meeting people's requirements. Wool fiber has excellent properties such as good elasticity, full hand feeling, good warmth retention, good moisture permeability, softness and a certain degree of water repellency, but it is a protein fiber with poor antibacterial properties and low strength. In order to make up for these shortcomings of wool There are studies on blending wool with other fibers. For example, the patent 201010566931.x blends acrylic fiber with wool. Because acrylic fiber is a chemical fiber, its blended yarns and fabrics have poor moisture absorption and are easy to stain, an...
