Cashmere refers specifically to cashmere, which is a thin layer of fine velvet covering the roots of the goat's coarse hair. It grows out when it is cold in winter to resist the wind and cold, and it falls off after warming in spring (note that it is down, not goat hair!). Cashmere production is rare and expensive, known as "soft gold". On average, the wool of 5 goats is enough to weave a cashmere sweater. The diameter of cashmere is generally less than 17 microns, and the average diameter of good cashmere is less than 15 microns. It should be known that the diameter of human hair is about 75 microns. There is basically no comparison between wool and cashmere. The warmth retention factor of cashmere is twice that of wool, and the outer scales are finer and smoother than wool. It is thin, light, soft, smooth and warm. It is all the textile materials that humans can use at present are incomparable. 

  Merino wool is the wool closest to cashmere, its fineness is second only to cashmere, and its diameter can reach about 20 microns.Merino wool can be divided into different grades according to thickness, among which only superfine Merino is really good wool.Superfine Merino, 70 or more, with an average fineness of less than 19.5 microns

Fine hair: 66-68 pieces

Medium hair: 64-66

Coarse wool: 60-64 pieces

The biggest feature of ultra-fine merino wool is its softness and delicateness, which does not prick the skin. Because the output is larger than cashmere and the price is not expensive, it can be used as a substitute for entry-level cashmere to some extent. Moreover, cashmere is easier to pilling, while ultra-fine merino is relatively less prone to pilling and is easier to take care of.

In terms of origin, the merino wool produced in Australia is the best. At present, about 40% of the merino wool in the world comes from Australia.
