Sewing thread is made from materials like cotton, polyester, and nylon. It must have several key properties to perform well for sewing, including good tensile strength to hold seams securely, tenacity for strength and reduced breakage, and optimum elongation to stretch before breaking. Other important qualities are proper lubrication to reduce wear, suitable twist level to prevent fraying, good elasticity to recover shape after tension, low shrinkage to prevent puckering, high abrasion resistance during sewing, and good color fastness to maintain its hue over time and washing.
