What is Yarn Count ? Type of Yarn Count ?

 

 

Yarn Size or Yarn Number :

We want to be able to tell someone what the size of a yarn is,and make these numbers comparable for different materials. If we just reported the diameter of the yarn, we would not be able to give accurate numbers because the edges of a yarn are fuzzy, and yarns can be extended so they would be narrowed or distorted. To give us a measure of yarn size that is comparable for different materials, we use linear density or reciprocal of linear density, because the length and mass of the yarn can each be accurately measured.

Type Of Yarn Count :

• Direct Systems
• Indirect System

Direct Systems- Used for Filament Yarns :

• Terms of weight per unit length
• Denier•
Tex- weight in grams of 1000 meters of yarn
• Decitex- weight in grams of 10,000 meters of yarn, A dtex is close in
value to a denier.
• Can be reported as A/B
• Example 1000/200 which means this is a 1000 denier yarn with 280
filaments present

 

 Indirect System :

• The length of a hank depends upon the spinning system:
– Cotton system: 1 hank = 840 yards
– Worsted system: 1 hank = 560 yards
– Woolen cut system: 1 hank = 300 yards
– Woolen run system: 1 hank =1600 yards
Indirect System, the English system
