Yarn Count

There is a nice definition of yarn count according to textiles institute of UK, “a count is a number of indicating the mass per unit length or length per unit mass of yarn of yarn”

In other word count can be defined as, the numerical values which express the fineness or coarseness of yarn. It indicates the relationship between length and weight also.

So, “Yarn count is a number which indicates the mass per unit length or the length per unit mass of the yarn”

Classification of Yarn count

Direct Count

Study my another article about direct yarn numbering (direct count) system

Indirect count (length/weight)

The length of a fixed weight of yarn is measured. The length per unit weight is the yarn indirect count. General features of all indirect count systems are the weight of yarn is fixed and the length of yarn varies according to its fitness.

Points should remember during the indirect count

• In indirect count system weight is fixed.
• Higher the yarn number finer the yarn and
• Lower yarn number coarser the yarn.

The following formula is used to calculate the indirect yarn count

Here,

N = Yarn count or numbering system

W= Weight of the sample

L = Length of the sample

l = Unit of the length of the sample

w =The unit of weight

Some indirect yarn count system

•  English count system, Ne: No of 840yd lengths per pound
• Metric count, Nm: No. of kilometers per kilograms
• Woolen count (YSW): No. of 256 yd lengths per pound (lb)
• Woolen count (Dewsbury): No. of yd lengths per oz
• Worsted count, Nek: No. of 560 yd lengths per pound
• Linen count, NeL: No. of 300 yd lengths per pound

Discussion

English Count

English count indicates how many hanks of 840 yards length weighs one pound.

That means, if count 40 Ne, then it means 40 hanks (bundle) of 840 yards will give 1 pound weight.

(Note: So, for gaining 1 pound weight, 840 yards long how many yarn bundle we will in need, this require a number of bundles are the English count of this yarn.)

Here count 40 Ne means, 40 bundles of yarn with 840 yards length will be required to get 1 pound to weigh.

So, hopefully, it was helpful for you to understand English count properly. If you like it do not forget to put down your valuable comments and share on facebook

Direct Yarn Numbering (Yarn Count) System

The count is a numerical value which is used to express the fineness or coarseness of the yarn. yarn count also indicates the relationship between the length and weight of the yarn. So, the definition of yarn count, we also can say yarn count has been introduced as a certain ratio of length to weight or weight to length.

Types of yarn count

There two types of yarn count system. They are as follows.

1. Direct Count System
2. Indirect Count System

Direct Count System

The direct count is determined by the weight of a fixed length of yarn. The weight per unit length is the count (direct count). The common features of all direct yarn count systems are the length of yarn is fixed and the weight of yarn varies according to its fineness.

We should remember in direct yarn count system

• Indirect count system Length is fixed.
• Higher the yarn number coarser the yarn and
• Lower yarn number finer the yarn.

The following formula is used to calculate the direct yarn count

N = (W × l)/L

Here,

N = Yarn count or numbering system

W = Weight of the sample

L = Length of the sample

l = Unit of the length of the sample.

Some direct yarn count system

1. Tex system
2. Denier system
3. Decitex
4. Militex
5. Kilotex
6. Jute count

A brief definition of the above direct count system

As I have given the definition above, now here I am going to present a brief definition of the above direct count system.

Tex system    : Number of grams per 1000 meters.

Denier            : Number of grams per 9000 meters.

Decitex           : Number of grams per 10,000 meters

Militex            : Number of milligrams per 1000 meters

Kilotex            : Number of kilograms per 1000 meters

Jute count     : No. of pound (lb) per 14,400 yards

Indirect Count System: (Will discuss in my next article. Remain with us.)

Discussion

Example :

Now I am going to discuss direct yarn count system with an example so that we can understand it more clearly.

• Suppose 35 Tex,

What does 35 Tex define?

35 Tex means 1000 meters of yarn weighs 35 gram. If 1000 meter long yarn gives 35-gram weight then it is called 35 Tex. Hope it is clear now.

Others direct yarn count system also define so,

Wish it was helpful. Now I am going to ask you some question about direct count system. Try to solve these questions by yourself. Or, you can also give your answer as a comment below the post. I will discuss these following question in my upcoming post. If you have any other question never hesitate to ask me.

Questions :

1. 20 Tex defines…………………
2. 35 Denier defines………………..
3. 35 Tex defines………………………
4. 10 Decitex define…………………….
5. 5 Kilotex defines………………………..
6. 10 Jute count defines……………………..

Calculation of Yarn English Count

English Count

English count indicates how many hanks of 840 yards length weigh one pound. That means if count 40 Ne Than it means 40 hanks(bundle) of 840 yards will give 1 pound weight.

(Note: So, for gaining 1 pound weight, 840 yards long how many yarn bundle we will in need, this require a number of bundles is the English count of this yarn.)

• Why calculation: Most of us are fear from count calculation. But we should have a common sense of calculation to be good textile personnel.

Let’s try to solve the following problem of English count

On one cone there are 9800 m yarns which weigh 490 gm. What is the English count of this yarn?

We know,

For Ne(English count),

So, Here count 12 Ne means, 12 bundles of yarn with 840 yards length will be required to get 1 pound weight.

So, wish it was helpful for you to understand English count properly. If you like it doesn’t forget to put down your valuable comments and share on facebook
