Yarn is a continuous spun strand, functioning as an intermediary material derived from various fibers, which can be either natural (such as cotton, wool, or silk) or synthetic (such as acrylic or polyester). The process of creating yarn involves drafting and twisting fibers to achieve consistent strength and diameter. The physical characteristics of the yarn, including its staple length, twist rate, and yarn count, significantly determine its final performance when used in weaving, knitting, or other textile applications. Functionally, yarn facilitates the formation of larger textile structures, providing the foundational component for garments, upholstery, and various crafts, making its structure and material science integral to the modern textile industry.
