Yarn Count Measurement Organization

  • Share
definition of yarn count:
Yarn count is a number, which express the fineness of coarseness of yarn. It is determined past its bulk per unit length. 

Yarn count measure system:
Yarn count measuring techniques are 2 types.

  1. Direct system
  2. Indirect organization

one. Direct system:
Here count is calculated past measurement weight of fixed/definite length. Tex, Denier and pounds/spyndle are the cite of direct organisation yarn count.

Jute Yarn

Tex:
Weight inwards grams per kilometer fiber or yarn is called Tex.

Example,

If ane km length of filament/yarn weight is x gm, then filament/yarn count is 10 Tex.
If one km length of filament/yarn weight is 25 gm, and so filament/yarn count is 25 Tex.

Denier:

Weight in grams per ix kilometer fiber or yarn is called denier.

Example,

If ix km length of filament weight is 10 gm, so filament count is 10 Denier.
If 9 km length of filament weight is 25 gm, and then filament count is 25 Denier.

Relation betwixt Tex as well as Denier: 

one Denier = nine Tex

Example,

If a filament count is 10 Tex, so this filament count is 90 Denier.
If a filament count is 20 Tex, so this filament count is 180 Denier.

Pound/Spyndle:
Weight inwards pounds per 14400 yards of jute yarn is called pound/spindle.

Example,

If 14400 yards length of jute yarn weight is 7 pounds, and then yarn count is vii pound/spindle.
If 14400 yards length of jute yarn weight is ix pounds, so yarn count is 9 pound/spindle.

ii. Indirect organization:
Here count is calculated past measuring length of a fixed/definite weight. English (Ne), Metric (Nm), woolen too worsted are the cite of indirect organisation yarn count.

English (Ne) count:
No of 840 yards per pounds is called English language (Ne) count.

Example,

If (20×840) yards length of yarn weight is ane pound than its English language (Ne) count is twenty.
If (45×840) yards length of yarn weight is 1 pound than its English language (Ne) count is 45.

Metric (Nm) count:
No of kilometer per kg is called Metric (Nm) count.

Example,

If 20 kilometer length of yarn weight is i kg and then its Metric (Nm) count is xx.
If 35 kilometer length of yarn weight is 1 kg so its Metric (Nm) count is 35.

Woolen count:
No of 256 yards per pounds is called woolen count.

Example,

If (30×256) yards length of yarn weight is i pound and so its woolen count is xxx.
If (45×256) yards length of yarn weight is one pound so its woolen count is 45.

Worsted (NeK) count:
No of 560 yards per pounds is called worsted count.

Example,

If (20×560) yards length of yarn weight is i pound and so its worsted count is xx.
If (30×560) yards length of yarn weight is one pound and then its worsted count is thirty.

Linen (NeL) count:
No of 300 yards per pounds is called linen count.

Example,

If (25×300) yards length of yarn weight is 1 pound so its linen count is 25.
If (45×300) yards length of yarn weight is i pound and then its linen count is 45.

Conversion of yarn count:
English language (Ne) ten Tex = 590.5
English language (Ne) 10 Denier = 5315
English (Ne) = Metric (Nm) x 0.59
Metric (Nm) = English language (Ne) 10 i.seven

At a glance we tin can see conversion of yarn count in below table:

Numbering of Ply yarn:

Direct System
Indirect System
NR = N ten n
NR = Ply yarn count (termination count)
north = Single yarn count (Tex, Denier, Pounds/spindle)
n = No of yarn inward ply
          north
NR = ……
          n
NR = Ply yarn count (final result count)
N = Single yarn count (Ne, Nm, Woolen, Worsted, Linen)
n = No of yarn in ply.

CV% way Co-efficient of variation of information. CV% count agency variation of yarn count.

C.S.P. (Count Strength Product) = English language count (Ne) 10 Lea strength inwards lbs.

Lea:
lxxx layer of yarn inward which each twelvemonth circumference is 1.five yards. So, in that location are 80×1.five = 120 yards inward ane lea.
