What is RKM value of yarn?

What is RKM of yarn?

RKM is abbreviation of Resistance per kilometer. It is an important yarn quality parameter without measurement units. It is calculated from the data of single yarn strength tests performed on manual or automatic single yarn testing installations, for example Uster Tensorapid 3 or Tensojet.

What is RKM value?

RKM is the short expression for “Reisskilometer” – “Breaking-kilometer”, which is an unit out of date. E.g.: a Cotton-yarn with 15 RKM means, it would break of its own weight, if you wind off 15 km of the yarn and hang it up in 15km.
