What is yarn count?

Ans- Count is a numerical expression, which defines the fineness or coarseness of yarn.

According to the textile institute " count is number indicating the mass per unit length" & Length per unit mass".

What types of yarn numbering system?

Ans- There are two basic types-

1- Direct System (Mass per unit Length)

2- Indirect System (Length per unit Mass).

What is the Cotton count?

Ans- It is defined as the length of a number of hanks of 840 yards per pound of yarn.

What is 30 Ne?

It is defined as the 30 numbers of hanks of 840 yards (840 yards x 30 hanks) of length per pound.

What is a counting system?

A counting system is a method to express the yarn fineness and thickness. 

DIRECT SYSTEM

In this system, count indicates the Mass per unit length.

Name of the System	Weight Unit	Length Unit
Denier (D)	1 Gram	9,000 meters
Tex (Tex)	1 Gram	1,000 meters
D tex	1 Gram	10,000 meters
Jute, Hemp	1 Pound	14,400 yards

 

In this system higher will be the count Coarser will be the yarn.

 

 

INDIRECT SYSTEM

In this system, count indicates the length per unit mass (weight).

Name of the System	Weight Unit	Length Unit
Cotton English System (Ne)	1 Pound	Hank of 840 yards
Cotton Matric	1 K.G.	Hanks of 1000 Meters
French Count (Nf)	1.5 K.g.	Hanks of 1000 Meters
Worsted	1 Pound	Hanks of 560 yards
Linen	1 Pound	Hanks of 300 yards

In this system higher will be the count finer will be the yarn.

Method to calculate the actual weight of Warp required:

For Direct System-

If the count is in Tex system (tex):

Then the actual weight Warp yarn required (In gram)

= Total Nos of Ends x warp Count x Length of fabric in meters

                                         1000

 

For Indirect System-

If the count is in the Cotton English system (Ne):

Then the actual weight Warp yarn required (In pound)

=      Total Nos of Ends x Length of Fabric (In yard)

                   Count of Yarn x 840 yard

As we know that the wastage of yarn has occurred in different stages of preparatory the process that is warping, winding & weaving etc. So during the calculation of the actual weight of warp yarn required including wastage, then simply add wastage %.

 Method to calculate the actual weight of Weft required:

For Direct System-

If the count is in Tex system (tex):

Then the actual weight of the Weft yarn required (In gram)

= Reed width (cm) x picks/Cm x Length of Cloth in meters x Weft Count

                                         1000

For Indirect System-

If the count is in the Cotton English system (Ne):

Then the actual weight Weft yarn required (In pound)

=      Reed width (Inch) x Picks/Inch x Length of Fabric (In yard)

                   Count of  weft x 840 yard
