Knitting Variables

Yarn count: - Yarn count indicates the fineness of yarn. It varies according to weight with length of the yarn.

Yarn twist: - It is the torsion of yarn which help the fibers to adhear with each other.

Spinning system: - This is the systematic way of giving torsion to the fibers.

Yarn ply: - It is the number of ply of the yarn which depends on the required gsm of the fabric.

Stitch length: - It is the length of the yarn which forms a single loop in a knitted fabric. If stitch length is increased, fabric gsm is decreased & vise versa.

Yarn tension: - It is the given tension on the yarn during feeding in circular knitting machine. It depends on the required gsm of the fabric. If yarn tension is increased, then stitch length is decreased and fabric gsm is increased. And if yarn tension is decreased, then stitch length is increased and fabric gsm is decreased.

Take down tension: - It is the tension created by increasing fabric take up roller speed.

Yarn quality: - Fabric quality depends on the yarn quality. As for example, for producing slub single jersey we need slub yarn.

Machine gauge: - It the number of needle in one inch area of a cylinder. G.S.M (gm/m): For knitting it is the main parameter. It is controlled by loop length. If loop length increases GSM will decrease and vice versa. It is measured by GSM cutter & electric balance.
