Introduction
When overloading the fabric on the chain pin, which improves the GSM of the fabric, the width of the fabric changes and decreases. When the fabric GSM is reduced using a press machine, feed the fabric lower with the feed roller to the chain pin and the fabric GSM is reduced.

- Determination of yarn count
- Determination of WPI
- Determination of CPI
Yarn count refers to the numerical expression by direct or indirect system of the fineness and coarseness of the yarn. For indirect system, more yarn count is thin and less yarn count is thick. WPI refers to (Wales per inch) which means number of Wales loops per inch. an inch in a knit fabric.
WPI effect on GSM of textiles. If GSM increases WPI (wales per inch), also increase after compaction. CPI refers (loop per inch), which means that there is of course no loop per inch in a knitted fabric.

Conclusion
To complement this report, we studied the effect of fabric structure (before and after condition) on the compact machine. We use four types of fabrics to complete this report Single Flannel, Rib (1×1), Lacoste and Wool. We saw most of the time WPI CPI and Stitch length is increased in case we want to do GSM increase.
But in the case of thread count, the value sometimes increases and sometimes decreases in case of increasing GSM. We have evaluated the research after concluding how it affects the physical properties of the fabric for compact machine use. And also we studied on the compaction machine how it affects the physical properties of the fabric for changing the GSM.
The machine operator sets the fabric width on the machine monitor and accordingly the fabric from the machine. As the GSM was increased, the fabric width decreased.
