**How to Calculate the Nep Count from Card Web**

**Nep Count:**

Nep

**count**is the number of neps per 100 square inch of card web forming a standard hank of sliver of 0.12 Ne on a 40 inch wide card.

**Mathematically, n**= m X 100

Where, m = No of neps per inch 2 card web

**Problem:1**

**A 42” wide card web of multiplying 100 of the mean value per square inch. Calculate the nep count of that card web.**

**Solution:**

**Nep count, n**= m X 100 = 0.13 X 100 = 13

**(ANS)**

**Problem:2**

**4 kilotex is produced from a web of card width 38” after testing 5 cells web formed to contain nep. Calculate nep count.**

**Solution:**

Sliver hank = 4 Ktex = 590.6/4000 Ne = 0.14765 Ne

Card width = 38”

No. of cells = x = 5
