# Yarn Number or Count Measurement System

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.

1. Direct System
2. 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
