The most expensive and desirable cashmere hair is meticulously hand combed or carefully sheared from the cashmere goats during the spring, when they naturally shed their winter coats. Skilled cashmere processors are capable of retaining the longest hairs from the goat’s undercoat; the longer, thinner hairs can be more tightly woven into stronger yarn.
Some good things written above which explains why cashmere jumpers can cost so much. The good cashmere is more labour intensive to harvest, and it isn't harvested with machines which [I think] result in making the fibers shorter than they need to be.
the longer, thinner hairs can be more tightly woven into stronger yarn.
This quote is funny. The top Italian and Scottish mills use the top cashmere which would be thinner hairs, yet Scottish cashmere is generally more tightly woven and dense than from the Italian mills. The Scottish ply is often thicker too.
pure cashmere makes up just a fraction of that amount, 6,500 tons (PDF). Compare that figure with the massive 1.08 million metric tons of wool (PDF)
Just goes to show how rare cashmere is, but it makes one appreciate how special the old vintage Scottish cashmere jumpers are. One day one won't be able to get those vintage jumpers anymore. Many were for the wealthy and were probably in short supply, so any vintage is a treat that future generations will never experience. The old skills have probably died out too along with the quality.
appetite for luxury goods, and you understand why cashmere remains an expensive commodity.
They talk about luxury, but little is luxury compared to the golden age of cashmere. Hermes made-in-Scotland is definitely luxury (Barrie/Chanel), even in this modern day, especially with it's dense tight thick ply weaves and m.o.p buttons etc, but no other cashmere strikes me as luxury because much of it has an average weave with a thin ply (skimps on cashmere) and pills and has plastic buttons where-as Hermes is special because it doesn't skimp, but not as special like it used to be. I have cashmere jumpers from Brunello Cucinelli and Loro Piana etc, but none are true luxury Italian cashmere jumpers.
High-quality long-fiber cashmere, however, remains scarce as heritage and luxury brands such as Italy’s Loro Piana, where you can easily spend thousands of dollars for a single cashmere sweater, buy up the majority of premium-grade cashmere. The yarn spun from shorter and broken cashmere filters down into the mass market, though sometimes higher-priced fashion brands use it, too, so you can’t rely on price as an indicator of quality.
Explains why prices can be high. You get what you pay for.
According to Derek Guy of Put This On, “the best cashmere sweaters came by the way of Scotland prior to the 1990s,”
He is right. Ballantyne after the 80's was never that good. Ballantyne before the 90's was EXCELLENT and unbeatable. They made a lot of hard minimally processed hard cashmere that rarely pilled and made to last longer than anything else. Pringle also made some hard cashmere on occasions, but Ballantyne was king imo. Those 50's, 60's 70'sand 80's Scottish jumpers were WOW, you don't see that quality anymore. Always loved Lyle & Scott too, they had a nice thick spongy cashmere that was truly unique.
