System of Yarn Count Conversions

Conversion of Count System:
We can convert the value of count from one to other systems by following only some formulas. There are 4 systems for yarn count conversions from one system to another system.

System of Yarn Count Conversions:

1. Conversion from direct to direct
2. Conversion from indirect to indirect
3. Conversion from direct to indirect;
4. Conversion from indirect to direct

There are two formulas to convert the yarn count as given below:

1. Unknown count = Multiplying converting factor X Given the count
2. Unknown count = Constant / Given count

Here the first one is used for the first two groups of conversion (direct to direct & indirect to indirect) and the second one is for the last two groups including direct to indirect & indirect to direct.

Before reading this conversion system you should read the following articles, as a result, you can understand easily.

1. Yarn Count Conversion Calculation from One System to Another
2. Direct System of Numbering Yarns and Calculations
3. Indirect System of Yarn Numbering and Calculation

The table of converting factor and the count constant is given below:

Direct to Direct:

Known yarn count in	Multiplying converting factor for the unknown count
	Tex	Denier
Tex	——-	9
Denier	0.1111	——
Jute count	34.45	310

Example:

Denier of unknown count = Tex (known count)  X  9
Tex of unknown count = 0.1111  X  Den or Jute count

Indirect to Indirect:

Known yarn count in	Multiplying converting factor for the unknown count
	Metric (Nm)	Worsted
Cotton (Ne)	17	1.5

Example:

Metric Count = 17 X Known cotton or worsted count
Worsted Count = 1.5 X Known cotton or Metric count

Indirect to Indirect & Direct to Direct:

Known yarn count in	Constant
	Tex	Denier
Cotton	590.5	5315
Metric	1000	9000

Example:

Metric = 9000 /Known Den count
Denier = 5315 /Known Ne

If we see the yarn conversion measurement system at a glance then the concept will be clear about the conversion of yarn count.

Yarn Count Conversion formula:

• Denier = 9 X Tex
• Ne X Denier = 0.5315
• Metric X Tex = 1000
• Tex X Ne = 590.5
• Ne = Metric X 0.5905
• Metric X Denier = 9000
• Tex = 34.45 X lb/ spyndle
