Knitted fabrics differ from woven fabrics in the way the yarns are formed within the fabric. The needle assembly is a crucial component of the textile process, encompassing different types of knitting weaves and knitting methods. By adjusting the yarn type, knitting technique, and knitting tension, fabrics with varying feel and physical properties can be produced to meet diverse customer needs and style requirements.
