Gorgeous cardigan with beautiful extra-special buttons on grosgrain ribbon foundation. Nothing made like this today. What is "Kharafleece"? It was Jantzen's exclusive blend of lambswool, Vicara, and nylon yarn that was mothproofed by Mitin. Vicara was a fiber produced by the Virginia-Carolina Corporation. It was made from the extruded plant protein Zein, which comes from corn. Vicara was soft as cashmere, washable, and took dyes well. It had to be blended with other fibers, though, as it was not as durable. Vicara production was discontinued in 1958 due to the advent of better performing synthetic fibers. If you have a Kharafleece sweater by Jantzen, you can properly date it prior to 1959.
