**Yarn Count:**

We can define yarn count as the coarseness or fineness of the yarn. It is just a numerical expression. There are main two types of yarn count measuring systems. One is direct count and another is indirect count system. Here, we will know the yarn count in the direct system and indirect system.

We can measure the yarn count from the following formula:

…………………………..590.5 x 16.1

Yarn Count = ……………………………….

……………………..S.L. x Grey G.S.M.

**Standard yarn count measuring table: **

**Indirect System:**

In this system, the yarn count expresses the number of the length in one weight unit. That means the Weight Unit is fixed & the Length Unit is variable here.

By the following formula yarn count is expressed in an indirect system:

…………………………………w x L

Indirect count: Ne = ……………..

…………………………………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.

**Yarn Count in Direct System and Indirect System:**

System |
Unit weight |
Unit length |
Uses |

English (Ne) | 1 lb | 840 yds | Cotton yarn |

Metric (Nm) | 1 kg | 1 km | Cotton yarn |

Worsted | 1 lb | 560 yds | Worsted yarn |

Woolen | 1 lb | 256 yds | Woolen yarn |

**Direct System:**

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

The following formula is used to calculate the yarn count:

………………………………W X l

Direct count: Nm = …………….

………………………………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.

Tex | Grams | 1,000m | Polyester |

Denier | Grams | 9,000m | Lycra |

D-Tex | Grams | 10,000m | Lycra |

Pounds/ Spyndle | Pounds | 14400yds | Jute |
