**Count:**

Count of yarn is very important to produce specific quality yarn. It is the coarseness or fineness of the yarn. On the other hand, we can say the count is a number is determined the mass per length or the length per unit. In this article, we will discuss the yarn number or count measurement system.

**Count Measurement System: **

There are two systems for the measurement of the count.

- Direct System
- Indirect System

**1. Direct System:**

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

**2. 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
