Camlet

Camlet, also commonly known as camlot or camblet, is a woven fabric that might have originally been made of camel or goat's hair, later chiefly of goat's hair and silk, or of wool and cotton. The original form of this cloth was very valuable; the term later came to be applied to imitations of the original eastern fabric.
The suit, dated to 1647 and which belonged to the Charles X Gustav of Sweden is made from wool camlet.
In the 18th century, England, France, Holland, and Flanders were the chief places of its manufacture; Brussels exceeded them all in the beauty and quality of its camlets, followed by England.
A variety of terms have been used for camlet in different forms:
Manufacturers of camlets had to take care not to introduce any unnecessary pleats in the fabric, as they were almost impossible to undo. This difficulty was so notorious, that a proverb existed, stating that someone "is like a camlet—he has taken his pleat."
Etymology.
The origin of the term is uncertain. While certain authors reference camlets as originally being made of camel hair, others believe it is from the Arabic "seil el kemel", the Angora goat. According to Chambers's Encyclopaedia, it comes from Arabic "chamal", meaning fine.
French scholar Gilles Ménage determined that "camlet" was derived from "zambelot", a Levantine term for stuffs made with the fine hair of a Turkish goat, probably the Angora goat, from which comes the term "Turkish camelot". Bochart claimed "zambelot" was a corruption from Arabic. Others called it "capellote", from "capelle", she-goat. Still others have sourced "camelot" from the bare Latin "camelus", so that "camelot" should properly signify a fabric made of camel hair.
