My company changed its name from Alphatech Corporation to AlphaInsight today, and as part of the rebranding, gave us beautiful blue oxford shirts. They are 87% polynosic.
According to the web, "Polynosic is a high wet modulus rayon." High wet modulus means when it gets wet, it maintains shape. Low wet modulus would be those rayons that get all wacky if you wash them instead of dry cleaning them. Apparently the brand name is Modal (tm). In Europe, rayon is called "Vicose" on all the labels, but technically, Vicose is a specific form of rayon, which is low wet modulus. Rayon, if you care, is my favorite textile. For me, rayon serves as a non-staticy version of polyester. It can be molded into almost anything, and can have beautiful stability and wrinkle resistance. I've worn a certain rayon skirt about once a week for the past 8 years, under trying circumstances more often than not, and it is still looking beautiful.
(Staticwise, since I have long hair, in the winter static electricity is one of the main axes of my life. I spend way too much mindspace in the winter months designing coping strategies for zapping myself on everything I touch. Wearing rayon clothing is like entering a force field.)
I'm pretty excited about all the new fabrics out there that have blossomed since they did that huge PR blitz with Tencel a few years back. It's nice to know that we homo sapiens have still got the touch with that whole fur/scale analog strategy.
