**How to Calculate Winding Efficiency with Example**

Winding:

Winding:

**Winding**is basically transferring a yarn from one type of package to another. This simple definition may make the winding sound like a trivial process, however, it is an important and essential process in warping and spinning for ring spun yarns.

**Winding Efficiency:**

The ratio of actual production and calculated production is called winding efficiency. It is expressed as percentage. The efficiency of a highly automated winding operation is calculated by modification of the mathematical model developed for a similar problem.

Actual Production

**Winding Efficiency**=

**……………………………**X 100

Calculated Production

*If you want to understand this problem then before you should must read the following articles*

**Note:****Example:**

**How long will it take for a winder to wind 3.00 lbs of 16 Ne yarn if the winder operates at 745yd/min. with the efficiency 95%?**

We know that,

= L / V

**Time, t**= length / speed= L / V

**Here,**- L = Length of yarn in the package
- Speed, V = 745yd/min.
- Weight of the yarn in the package, W =3.00 lbs
**Yarn count**, Ne = 16

L × w

**Yarn count, Ne**=

**………………………………..**

W × l

Ne × l × W

**Therefore, L**=

**……………………………**

W

16 x 3.00 x 840

=

= 40,320 yds

40,320

**So, t**=

**.....................**

745

= 54.12 minutes (assuming no breaks or stops)

**To consider the effect of efficiency,**

54.12

**Therefore, t**= …………

0.95

= 56.97 minutes
