Knitting is a textile manufacturing process involving the systematic interlooping of yarn using two or more needles to create a flexible, interlocking structure. The fundamental mechanical action involves creating continuous loops of fiber material that are passed through previously formed loops. This process dictates the inherent elasticity and resilience of the resulting fabric, allowing knitted goods to stretch significantly while maintaining structural integrity. The properties of the finished textile are highly dependent upon the type and tension of the source fiber—whether natural, such as cotton or wool, or synthetic, such as polyester—as well as the specific pattern and gauge of the looping mechanism employed.
