Count
Count is the numerical aspect which expresses coarseness or fineness of yarn. It agency that, the yarn count refers how much a yarn is fine or course. We too tin state that the yarn count unwrap indicates the length of yarn inwards relation to the weight.

But according to the Textile Institute, they define yarn count as “Count, a unwrap indicating the mass per unit of measurement length or length per unit of measurement mass of a yarn”.

Yarn count is too known every bit yarn unwrap or linear density.

System of Count Numbering
Different organization or units are used to measuring the yarn count or yarn unwrap which mostly depends on the stuff used for preparing the yarn together with the surface area where it was manufactured.

Count numbering organization tin endure grouped every bit next categories;

• Analytical System &
• Instrumental System.

Analytical System
Actually this procedure is consisting alongside another systems based on several calculations together with this is why it is called Analytical system. The systems are including;

1. Direct System &
2. Indirect System

Direct System
In this procedure the count is based on the unwrap of weight units inwards a length unit. Thus the size or bulkiness of the yarn is straight proportional to the count number. H5N1 coarser yarn volition accept a higher count unwrap spell a finer yarn volition accept a lower count number.The organization is used for really fine together with really coarse yarns. This organization is mostly used for silk, jute etc.

We tin run inwards this organization past times next categories;

• Tex
• Denier &
• Jute Count

Tex
It tin endure defined every bit the weight introduce inwards yard meter of yarn inwards grams where length of yarn is fixed. It agency that, for example, if at that spot is a yard meter of yarn together with accept a weight of 20gm hence the yarn count volition endure 20tex. Because tex refers the weight inwards gram of unit of measurement length.

Here is the equation for determining the yarn count inwards Tex;

              Weight inwards grams
Tex = …………………............……
          Length inwards yard meter

                Sample weight inwards gm X Unit length (1000m)
Or, Tex = ………………………………….....................……………
                          Sample length inwards meter

An extra qualification of Tex organization nosotros know that it is known every bit the universal procedure of yarn count which is innovate past times International Standard Organization (ISO) alongside several textile scientists, technologists together with manufacturers.

Denier
It is defined every bit the weight of yarn thread inwards grams presented inwards per 9000 meter length of that yarn. It is simply similar most Tex organization solely has to alter the unit of measurement length from 1000m to 9000m together with hence the equation of denier becomes as;

           Sample weight inwards gm X Unit length (9000m)
Den = ………………………………………..........................………
                     Sample length inwards meter

As an instance nosotros tin state most 454 meter of yarn containing v gram of weight hence the count inwards Den volition endure

           half-dozen X 9000
Den = …………
               454

= 118.9 den

Jute Count
The weight of yarn of 1 lb introduce inwards 14400 yds length of yarn is known every bit jute count or pounds per spindle.

Indirect System
In this organization the count of yarn expresses the unwrap of length units inwards ane weight unit. Higher the count finer is the yarn. This organization is to a greater extent than oftentimes than non used for cotton, worsted, woolen, linen (wet spun), etc. The indirect organization covers the bulk of the of import types of yarns. The count is based on the unwrap of length units inwards ane weight unit

This is too having some sub-system every bit following;

• Cotton Count
• Metric Count &
• Worsted count.

Cotton Count
Actually past times the term cotton fiber count tin endure defined every bit the unwrap of hanks of 840 yds presented inwards 1 lb weight of yarn. This is too known every bit British or English linguistic communication count. It is denoted past times Ne

The equation of cotton fiber count measuring is every bit following;

                   Length inwards hanks of 840 yds
Count, Ne = ………………………............……

                           Weight inwards lbs

              Sample length inwards yds X unit of measurement weight
Or, Ne = ……………………………...............………
              Sample weight inwards lbs X unit of measurement length

Now for an example, if nosotros reckon a yarn sample of 2000 yds alongside a weight of 0.08 lb hence the cotton fiber count volition endure

                      2000 X 1
Count, Ne = ……………
                    0.08 X 840

= 29.7 Ne

Metric Count
Metric count is limited yard gm or 1 kg weight of yarn tin contains how many numbers of hanks of yard meter. It is denoted past times Nm.

The formula of measuring metric count is;

                               Sample length inwards meter X unit of measurement weight
Metric Count, Nm = ……………………....................…………………
                                 Sample weight inwards kg X unit of measurement length

For example, if nosotros reckon a yarn of 2000m having the weight of 450g. So the count inwards metric organization volition be

                                   2000 X 1
Metric Count, Nm = ………………
                                 0.45 X 1000

= 4.4 Nm

Worsted Count
It is the unwrap of hanks of 560 yds presented inwards 1 lb weight of yarn is known every bit worsted count which is widely used for yarn composed past times wool.

Instrumental System
By this procedure count of yarn is measured past times using unlike sorts of musical instrument where whatsoever variety of calculation is non needed together with nosotros tin larn straight the yarn count. The machines which are mostly used of count measuring are given bellow;

1. Beesley Balance
2. Wrap Reel Balance
3. Quadrant Balance
4. Stubb Yarn Balance

1. Beesley Balance:
When a cotton fiber yarn is supplied inwards brusque length or removed from fabric, the count of yarn tin endure measured past times a particular type of residual is called Beesley’s balance.

Beesley Balance

2. Wrap Reel Balance
By this criterion method of count testing, the count of whatsoever type of a yarn tin endure calculated. In this organization yarn is measured past times the roll reel counter. In instance of cotton, the circumference of roll reel is 1 yd together with required yarn is 120 yds. Again inwards instance of jute, roll reel circumference is 2.5 yds together with required yarn is 300 yds.

3. Quadrant Balance
Quadrant residual is ane type of typical balance. This is lead reading instrument. The count tin endure straight mensurate from quadrant balance.

4. Stubb Yarn Balance
Stubb yarn residual is too worked on the footing of fixed length & fixed weight every bit similar a Beesley residual together with it is used to discovery the count of stuff sample. Here the unwrap of fixed weight yarn gives the count of yarn.
