Frequently Asked Questions | FAQs

What is the RKM of a yarn equal to?

The RKM is calculated by dividing the breaking strength of the yarn (expressed in cN/tex or grams per tex) by the linear density of the yarn (tex) and then converting the result from meters to kilometers.
Mathematically, the RKM can be calculated as follows:
RKM = (Breaking Strength in cN/tex or g/tex) / (Linear Density in tex) * 1000
The RKM is an important parameter in assessing the strength and quality of yarn. Higher RKM values indicate stronger yarn that can withstand higher tensile forces before breaking. Yarns with higher RKM values are generally considered to be more durable and suitable for applications that require strength, such as in technical textiles or industrial fabrics.
