Conventionally, a velour fabric which is excellent in heat retention and excellent in touch as a kind of pile fabric is manufactured by a circular knitting machine (daimaru) or a jacquard machine. In general, circular knitting machines (daimaru) have the advantage of being more economical because the knitting speed is faster than the jacquard machine, while the velour fabric manufactured by the jacquard machine lacks the high visibility or the toughness to knit the formal garment fabric. There are inadequate disadvantages.

Conventional pile fabrics manufactured in circular knitting machines are knitted by a circular knitting mechanism, in which a sinker and a needle are operated by a single knitting cam and a single sinker cam to form a knitted fabric.
