Breakages are inevitable in yarns and threads. Being vulnerable to breakages, threads can prove expensive in the end product if not picked out accurately. The risk of thread breakage is far more with the use of cheap yarns made of inferior quality raw materials and less-sophisticated equipments.

For example:
A 12-head embroidery machine with a speed of 700 stitches/min. and an effective performance of 60% embroiders 420 stitches/min. or 25,200 stitches/h.
The Consumption of Yarn per hour lies at around 1,500 m which, if we base the calculation on No. 40, is equivalent to approx. Rs. 15.
In order to rectify a broken thread, the machine is switched off for approx. 10 seconds, representing a production loss of 504 stitches.
If a 20% cheaper yarn is used, leading to one additional broken thread per hour, the situation is as follows:

One broken thread per head per hour = 12 x down-time of 10 sec = 120 sec = a production loss of 10,000 stitches/hour

With a revenue of only Re 1.5 per 1,000 stitches, this represents a loss of approx. Rs. 15 per hour. Where billing is based on finished items rather than performance, the revenue loss is much greater.

Hence saving on yarn quality cannot be economical. Instead it can affect overall turnover.
