CPI And WPI / EPI And PPI Measuring System With The Magnifying Glass Setting Multiplier

In fabric structure; it is important to know, how much yarn is in length wise and width wise. To know the number of yarn in a specific fabric a measurement is done for this. For this yarn in inch is measured by the magnifying glass setting multiplier. It is a off line quality assurance system.



In knit fabric yarn is measure in course and Wales direction. CPI means yarn is in course per inch and WPI means Wales per inch.

Measure the CPI & WPI with the magnifying glass setting multiplier:

1. Take the fabric & marking 1 inch with the ball pen according to the Course & Wales wise of a knitted fabric.


2. Then set the marking point with the multiplier scale & counting the CPI & WPI of knitted fabric in 1inch.


3. Wales per inch and course per inch is counted by the magnifying counting glass.

In woven fabric EPI and PPI is measured to the number of yarn in a fabric. EPI means ends per inch and PPI means picks per inch. Number of yarn in warp direction is measured by EPI and number of Weft yarn in fabric is measured by PPI. In weaving beam is prepared by analyzing the fabric by magnifying glass setting multiplier.

Measure the EPI & PPI with the magnifying glass setting multiplier:

1. Take the woven fabric & marking 1 inch with the ball pen according to the warp & Weft wise of the woven fabric.


2. Then set the marking point with the multiplier scale & counting the EPI & PPI of woven fabric in 1 inch.


3. Ends per inch and Picks per inch are counted by the magnifying counting glass.

So, calculate CPI and WPI for knitted fabrics and EPI and PPI for woven fabrics.
