**Count:**

**Count of yarn**is very important to produce specific quality yarn. It is the coarseness or fineness of yarn. In the other hand, we can say count is a number is determined the mass per length or the length per unit.

**Count Measurement System:**

There is two systems for the measurement of count.

- Direct System
- Indirect System

**Direct System:**

In this counting system, the yarn number or count is the weight of a unit length of yarn. Here, higher the number, finer the yarn and vice versa. Here, the weight of yarn is fixed, length is variable.

**Formula:**W X l

**N = …………….**

w X L

**Where,**

N = Yarn count

L = Length of sample

l = Unit length

W = Weight of sample

w = Unit weight

**Commonly used units in this system of measurement are:-**

- Tex ( 1 Tex = 1g/ 1000m )
- Spyndle (1 Syndle = 1lb/14400yds)
- Denier ( 1 Denier = 1g/ 9000m )

**Indirect System:**

In this counting system the yarn number or count is the length of a unit weight of yarn. Here, lower the number, finer the yarn and vice versa. Here, the length of yarn is fixed, weight is variable.

**Formula:**L X w

**N = ………………..**

l X W

**Where,**

N = Yarn count

L = Length of sample

l = Unit length

W = Weight of sample

w = Unit weight

**Commonly used units in this system of measurement are:-**

- Cotton or English Count
- Metric Count
- Worsted Count
