Sewing thread is the yarn used to combine two or more fabric pieces together in garments, accessories, and other textile products. Thread may be comprised of the same construction and fibre content as the garment, but is often different. Thread encompasses the majority of the stress and strain from movement and needs to be strong and durable. It must resist breaking and be compatible with the rest of the garment in terms of color, care instructions, and construction. Major quality checks for sewing threads include construction (diameter and fineness), strength and elongation, shrinkage, twist, twist balance, and color. The other parameters include sewability, imperfections, finish, package density, and winding. Sewability is tested by sewing the thread in the intended fabric at the highest machine speed. The sewn fabric should consist uniform and consistent stitches, which indicates good sewability. Sewing thread should be free from imperfections such as knots, slubs, thick and thin places.
