Suppose of the Cashmere
We can suppose that Chinese imperators and nobles fitted Cashmere clothes, even if there isn’t any document attesting this. It seems that Marco Polo, in the XIII century, saw graffiti of domesticated goats inside some caves in Mongolia.
So, we can think that man raised and exploited these goats for milk, meat (a female can weigh 30-50 kg, while a male 40-80 kg) and to obtain clothes from their fleece in those countries since the old times.
Certainly, considering the particular isothermal qualities of cashmere, it was very useful to fit where winters are cold.
English began to import to Europe this wonderful texture only in the XIX century.
The first import of cashmere hair from China was made at the end of 1950 by “Filatura d’Angora”. In those years Italy didn’t still have diplomatic relationships with China.
