Determination of Thread Count of a given fabric by Beesley Balance


Yarn Count is a numerical expression that indicates the coarseness or fineness of a yarn. (or) A count is a number indicating the mass per unit length or length per unit mass of the yarn.

Beesley Balance


It is working on the principle of fixed weight and fixed-length system.

It is used for assorting the count of warp and weft yarns from a small sample of the fabric. It consists of pillar A which carries a cross beam B fulcrummed at a knife-edge at point C.

At one end the cross beam is a hook E upon which the yarn to be tested can be placed. The other end of the beam tappers to a point C. When the beam is in balance the pointer will coincide with the datum line or the arrow mark on the beam. The pillar is mounted on the base. The whole instrument is levelled by a levelled screw at one end of the base. The crossbeam has a small notch at point D to take the counterweight or rider. A template is also supplied with the instrument and it can be used to measure full cotton, 1/2 cotton lengths, samples of woollen and worsted yarns depending upon the material to be tested and the quality available, the said length can be chosen to cut the sample of length correspondingly marked.

The pointer is set directly opposite to the datum line, with no material on the counterweight in their proper places, by adjusting the levelling screw. The Counterweight (rider) for the particular length which is supplied with the instrument is chosen and suspended at the notch and for 1/2 cotton, the small rider is placed. Then the material is cut to the size of the template and then it is hung in the sample hook. The samples are added to the sample hook until the pointer comes in level with the datum line. At that stage, the threads are taken out and counted which gives directly the count of yarn taken for testing. if there are 30 threads in the sample hook at the balanced condition, then the count of the yarn is the 30s.

How to Determine Thread Count of a Given Fabric by Beesley Balance?


To determine the thread count of a given fabric by Beesley balance.


Template, Beesley balance, Marking pen, scissors, Needle, Pin.

Objectives of Experiment:

  • To Know about Yarn count.

  • To know about Template & Beesley balance.

  • To know how to determine the thread count by template & Beesley balance.


Template is a length measuring instrument that contains eight arms. When a sample has a short length (Fabric) which we cannot determine by the wrap reel then we use a template using that we can determine the length.

Template Measurements:

Cotton: 4.32 Inch

1/2 Cotton: 2.16 Inch

Linen: 1.543 Inch

Wool: 1.315 Inch

Worsted: 2.88 Inch

Working Procedure:

  1. Select the sample for which count need to be measured.

  2. Condition the sample at standard atmospheric conditions.

  3. Mark the fabric by using a Template and also mark direction (warp or weft).

  4. Cut the sample by using scissors.

  5. Unravel the yarns from the fabric according to the marking.

  6. Set the Beesley balance, make sure that the datum line and pointer are at the same line before placing the rider. If the datum line and pointer are not at the same line then adjust them by using Levelling screw.

  7. Place the rider on the notch.

  8. Now place the yarns (marked and cut) on the sample hook and check whether the datum line and pointer are matching, if they are not balanced then add yarns till it matches.

  9. Count the number of yarns required to balance that will be the count of yarn.

  10. Example: If there are 30 threads in the sample hook at the balanced condition so the count of the yarn is the 30s.


  1. Make sure that markings are done properly.

  2. Be careful while withdrawing the yarns from the fabric.
