Introduction:

The dissimilar end-uses require yarns of dissimilar thickness. The accepted agency to betoken the thickness of a yarn or cloth inwards diverse stages of yarn manufacturing is to order the yarn count or linear density. The length of the cloth is measured out, too hence weighed. Count is expressed equally the length per unit of measurement mass.The linear density is expressed equally volume per unit of measurement length. Each organization is referred to equally beingness either indirect or direct.

Objectives of this study:

1. To know nigh yarn count.
2. To know nigh the calculation of yarn count.

Theory:

Yarn count:
The yarn count is a numerical appear which defines its fineness or coarseness. It besides expresses atmospheric condition the yarn is thick or thin. Influenza A virus subtype H5N1 Definition is given past times the textile works life – “Count is a release which indicates the volume per unit of measurement length or the length per unit of measurement volume of yarn.

                          Length inwards yard x Weight Unit
Cotton count = ---------------------------------------------------- ………… (1)
                          840 yard x Weight inwards pound

Required apparatus:

• Digital Balance.
• Sample of yarn.
• Calculator.

Experimental procedure:
At first, a lea of yarn has been taken. Then the lea was weighted past times digital balance. The weight gram was converted to pound. Then the information were seat inwards equation (1). The count was calculated past times the equation. Finally average count possess got been calculated which is the cotton fiber count of this sample.

Experimental Data: 
 Table 1: Measurement of Yarn Count

Table 2: Measurement of Yarn Count CV%

Results:
The average count is 42 too the CV% is 5.95.

Discussion:
In this experiment, the yarn count of the given cotton fiber sample was determined past times wrap reel too analytical balance. It is a rattling piece of cake physical care for of determining yarn count. We must hold upwards careful nigh about steps of this process. We should hold proper tension of yarn when yarns are air current on roll reel. The weights should besides hold upwards taken rattling carefully. Otherwise the count tin possess got error. We besides should hold upwards aware nigh our torso produce inwards the lab. Otherwise whatever accident tin hold upwards occurred.

Conclusion:
It is a rattling piece of cake physical care for of determining yarn count. But a disadvantage of this physical care for is, it is slower than whatever other process. There involve to a greater extent than fourth dimension than about other process. However, it is hence much used physical care for equally it is hence piece of cake to hold upwards done.
