**What is yarn count | Different types of count**

**Yarn count**

The yarn count is a numerical expression which defines its fineness or coarseness. It also expresses weather the yarn is thick or thin. A definition is given by the textile institute – “Count is a number which indicates 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. The system is generally used 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.
