Acrylic yarn is made from synthetic, or human-made, fibers. It’s 100% acrylic fiber, which means it has no natural animal hair or cotton materials. Like other yarns, acrylic is formed into a continuous piece and wrapped into a ball, or skein, for sale for use in knitting, crochet, rug making, and other craft projects. Unlike natural fiber yarns, such as cotton, silk, bamboo and wool, acrylic varieties aren’t spun, but rather are twisted into long lengths.
Some acrylic yarns can be rather rough and scratchy. This is in contrast to the lighter, softer, airier natural yarns — especially the kinds made from hand or machine-spun animal hair. The appearance of the yarn can rarely be mistaken for natural types, although sophisticated, softer textures and colors help make acrylics look more genuine.
