# Yarn Count : Definition & Types

The Yarn Counts of the textile industry is crucial. Without this phrase, the spinning or weaving mills cannot function. Since it has a complete impact on product cost. Therefore, it is the most crucial phrase in the textile industry. We shall get more specifics about it in this post.

## Yarn Count

Its fineness or coarseness is expressed numerically by it. It also conveys the thickness or thinness of the yarn. The Textile Institute defines count as “a number indicating the mass per unit length or the length per unit mass of yarn.”

## Types Of Yarn Count

- Indirect system- English, Metric, Worsted.
- Direct system- Tex, Denier, Lbs/Spindle.

## Indirect Count

The count of yarn expresses the number of length units in one weight unit. Thus higher the count, finer the yarn. People use the system for cotton, worsted, linen (wet spun), etc.

w x L

Indirect count: N= _____________________

W X l

Where, W = The weight of the sample.

w = The unit weight of the system.

L = The length of the sample.

l = The unit length of the sample.

## Direct Count

The count of yarn expresses the no. of weight units in one length unit. Thus higher the count, coarser the yarn. The system is generally used for synthetic fibre, jute, silk, etc.

W X l

Direct count: N = ____________

w X L

Where,

N = The yarn number or, count.

W = The weight of the sample.

w = The unit weight of the sample.

L = The length of the sample.

l = The unit length of the sample.

## In Details:

**English system:** It is defined as the number of hanks (840 yds) per pound. count.

Length (yds) 1 pound

English count N =______________ X _______________

840 yds Weight (Pound)

**Metric system:** It is defined as the number of hanks (1000m) per kg.

Length (m) 1 kg

Metric count = ______________ X _______________

1000m Weight (kg)

**Worsted system:** It is defined as the number of hanks (540yds) per pound.

Length (yds) 1 Pound

Worsted count =____________ X ___________

560 (yds) Weight (Pound)

**Tex system or Lea count:** It is defined as the weight in grams of 1000 m.

Weight (gm) 1000m

Tex count =____________ X ______________

1 gm Length (m)

**Denier:** The number or, count in the denier system is the weight in grams of 9000 m.

Weight (gm) 9000m

Denier count = ____________ X ____________

1 gm Length

**Pounds per spindle (Jute system):** Count in the pound per spindle system is the weight in pounds of 14400 yards of yarn.

Weight (Pound) 14400 (yds)

Pound per spindle = ______________ X ______________

1 Pound Length (yds)
