Silk yarn is mainly made from natural fibers such as silk, or chemical fibers that are first made into long silk and then transformed into other forms as needed. Silk thread has the characteristics of smoothness and uniformity, strong luster, and high strength, and is often used as a thread for mid to high end clothing. Its structural characteristics are that the fibers are highly parallel, tightly arranged, and have strong regularity, making the yarn structure monotonous and generally less twisted. In terms of physical and mechanical properties, silk yarn has a high fiber strength utilization coefficient, small yarn diameter, high density, low fluffiness, relatively uniform mechanical properties, and high bending stiffness. Visually, the fibers are straight, the yarns are smooth, and the luster is good. In terms of touch, it feels hard, smooth, waxy (referring to fibers), and cold
