Quality control
•
•
•
•
•
•
•
The two main contributing factors to the quality control on knitting machines are.
Stitch density and stitch length.
Other contributing factors on the machines are.
Yarn tension [Input Tension] and fabric take down [Output Tension].
Other external contributing factors are.
Uneven thickness of yarn, package hardness, uneven winding, temperature ,humidity etc.
The gauge of machine .

Stitch density
•
•
•
•
Stitch density is used on both flat and circular knitting machines. For checking quality and reproducing the same fabric quality at a later date.
The total number of loops in a square area measurement = courses x wales.10 courses by 10 wales = 100.
If this changes the fabric will become thicker or thinner
Can be changed by yarn thickness , yarn twist , input tension , out put tension and stitch settings .
