System of Conversion of Yarn Count
Conversion of Count System:
We can convert the value of count from one to other system by followings only some formulas. There are 4 systems for conversion of yarn count from one system to another system.
 Conversion from direct to direct
 Conversion from indirect to indirect
 Conversion from direct to indirect &
 Conversion from indirect to direct
 Unknown count = Multiplying converting factor X Given count
 Unknown count = Constant / Given count
 Indirect System of Yarn Numbering and Calculation
 Direct System of Numbering Yarns and Calculations
 Yarn Count Conversion Calculation
The table of converting factor and the count constant is given billow;

converting factor for 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

Metric

Worsted


Cotton
(Ne)

17

1.5

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

Cotton

590.5

5315

Metric

1000

9000

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