| | QuiltingQuilting Thread| Quilting Thread Article | Thread is a type of yarn intended for sewing by hand or machine. Modern manufactured sewing threads may be finished with wax or other lubricants to withstand the stresses involved in sewing.Embroidery threads are yarns specifically designed for hand or machine embroidery. Spun yarn is made by twisting or otherwise bonding staple fibers together to make a cohesive thread.Twisting fibers into yarn in the process called spinning can be dated back to the Upper Paleolithic, and yarn spinning was one of the very first processes to be industrialized. Spun yarns may contain a single fiber, or synthetic fibers which have high strength, artificial lustre, and fire retardant qualities may be blended with natural fibers which have good water absorbance and skin comforting qualities, in different proportions, to manufacture yarn for fabric. The most widely used blends are cotton-polyester and wool-acrylic fiber blends. Yarns are made up of any number of plies, each ply being a single spun yarn. These single plys of yarn are twisted in the opposite direction (plied) together to make a thicker yarn. Depending on the direction of this final twist, the yarn will be known as s-twist or z-twist.
