The coil structure of the underpinning knitted fabric is fairly stable, the face is flat, the longitudinal pliantness is generally lesser than the transverse direction, and the fabric has different degrees of dispersibility and curling. There is tricot fabric for homewear as apparel on the request. It has two major types of fabrics, one is elastic fabric and the other is velvet fabric. The underpinning knitted fabric can be divided into a single needle bed and a double-needle bed.
