Pashmina refers to a fine variant of spun cashmere, the animal-hair fibre forming the downy undercoat of the Changthangi goat. Pashmina silk sarees are woven with fine silks extracted from the wool of the mountain sheep. The word pashm means "wool" in Persian, but in Kashmir, pashm referred to the raw unspun wool of domesticated Changthangi goats. Pashmina may refer either to the material or to the variant of the Kashmir shawl that is made from it. Both generic cashmere and pashmina come from the same goat, but generic cashmere ranges from 12 to 21 microns in diameter, whereas pashmina refers only to those fibres that range from 12 to 16 microns. The fabric is so subtle and smooth that real Pashmina silk saree can be passed through a small finger ring. You can wear Pashmina silk sari for casual and festive occasions.
The most popular pashmina fabric is a 70% pashmina/30% silk blend, but 50/50 is also common. Some manufacturers use the term pashmina to describe an ultra fine Kashmiri fiber; others use the term to describe a blend of cashmere and silk. If the item contains only cashmere, it should be labeled 100% Pashmina or All Cashmere, by the Wool Act or regulations.
