A Definition of Knit and Woven Fabric

Knit Fabric:

Knit fabric is a textile created by weaving loops of thread or yarn together using either knitting machines or hand knitting techniques, commonly referred to as knitting techniques.

Knitted fabrics are known for their stretch ability due to the loops woven within, enabling it to stretch and recover more quickly for comfort and flexibility. Common fiber types used are polyester cotton wool which make this versatile fabric comfortable as clothing options such as T shirts sweaters activewear as well as undergarment accessories and even headgear.

Woven Fabric:

Woven fabric refers to textiles constructed by interlacing two or more threads or yarns at right angles to form fabric. The horizontal threads are known as weft or filling, while the vertical threads are called warp. The interlacing of these threads creates a structured and sturdy fabric with little to no stretch.

Woven fabrics are commonly produced on weaving looms, where the warp threads are held under tension while the weft threads are passed over and under them to create different weave patterns. Fabrics can be created using cotton, linen and synthetic yarns woven together. Fabrics can then be used to manufacture clothing such as shirts and trousers as well as home textiles, accessories, bags or any other number of goods that meet our everyday needs.
