1. There are two main types of knitting: • WEFT KNITS • WARP KNITS Knitted Fabrics In weft knitting the loops of yarn are linked across the width of the fabric. In warp knitting the loops are linked in a vertical direction. Knitted fabrics are made from interlocking loops of yarn. Warp knitting machine

2. Weft Knitting Weft knitting is made using a single yarn. It can be made by hand knitting or by machines. • Characteristics of weft knits: • The fabric has high elasticity and stretch. • The loops of yarn trap air which retains body heat to keep us warm. • The right and wrong sides of the fabric look different. • the fabrics can lose shape easily. • Creases fall out easily. • The fabric can unravel and ladder easily. • Weft knitted fabrics curl up at the edges when they are cut.

4. Warp Knitted Fabrics In warp knitting the yarn loops vertically up the fabric and the process uses many yarns rather than one. The fabric does not unravel or ladder. It is an industrial process only. • Characteristics of warp knits: • The production system is fast so the fabrics are quick to make. • The fabric is elastic but it can keep its shape. • It can be cut and sewn easily as it lies flat when cut. • It is mainly used with synthetic filament yarns.
