You might have heard and seen a lot of “26/1 or 26/2” fraction when dealing with Cashmere. So what exactly is that fraction denoting?
26/1, It means in 1 kg of yarn there is 26 kilometer of yarn. 26/2, means there is 2x13km of yarn twisted together in 1 kg. So this means, 26/2 is thicker than 26/1. Additionally, as the numerator number increases, for example, to 100/1 then the cashmere product becomes thinner and finer. This is because there is 100 km of yarn in 1 kg, resulting in thinner and finer yarn.
