As known to all, wool harvest from young lambs differs in quality from that of older sheep. As the same saying, wool differs according to superior sheep or inferior sheep, and in no doubt difference exists between wool from live sheep and that from dead sheep, all that necessitates standards for the classification of fleeces.
There are four classification of wool as below explain.
Class-One Wool – Merino wool
Merino sheep is the best sheep species origin from Australia and it produces class-one wool.
Merino wool is the best wool without doubt which is relatively short, but this kind of wool fiber is strong, fine, and elastic and has good working properties. Merino fiber has the greatest amount of crimp of all wool fibers and has a maximum number of "scales": two factors which contribute to its superior warmth and spinning properties.
Class-Two Wool
Class-two wool is not so good quality as the Merino wool. Nevertheless, this variety wool is also very good quality with a large number of "scales", and it comes from sheep originated in England, Scotland, Ireland and Wales. It is 50-200 mm in length and has good working properties.
Class-Three Wool
Class-three wool has fewer "scales" and less crimp than Class-one and Class-two wools. This class of wool comes from sheep originated in the United Kingdom. This kind of wool fiber is coarser but smoother and it is about 100-455 mm long with good luster. Meanwhile, class-three wools are less elastic and resilient. They are nevertheless of good quality to be used for clothing.
Class-Four Wool
The final class wool is really coarse and hair like and this wool is less desirable, with the least elasticity and strength. These wool fibers are from 25-400 mm long, have relatively few "scales" and little crimp, and therefore, more smoother and more lustrous.
In no doubt, Consinee has superior pursuit on yarn material. And annually, Consinee group purchases a large scale of merino wool material to put into wool yarn production and rewards to world designers and consumers.
