[UPDATE: Oh, what I meant to say was:
“Local womenswear brand Amour Vert is a favorite for its combination of California cool with French chic—all with a major eco-conscious stamp of sustainability.”
Here you go, here’s your new T, straight outta “up-and-coming” Hayes Valley:
You see, it’s made out of rayon. Check it.
Here’s your release:
“San Francisco-Made Amour Vert Stays Close To Home For Its First Retail Store
SAN FRANCISCO, June 20, 2014 /PRNewswire/ — Contemporary eco-fashion brand, Amour Vert is happy to announce the opening of its first retail store in its home city of San Francisco. With all garments made and designed within a 20 mile radius, the store is the latest addition to the up and coming Hayes Valley neighborhood.
Amour Vert’s retail space reflects their commitment to sustainability. The environmentally conscious store features ecological ingredients and co-founders, Christoph Frehsee and Linda Balti employed local contractors and local interior design stores to bring the eco-forward store to life. Bringing the environment indoors, a focal point of the store will be a living wall, which the brand is installing with the help of San Francisco native, model and philanthropist, Lily Kwong. The wall will serve as a nod to “green love” – the English translation of the brand’s French name.

I’ll tell you, I don’t know how our Austrian “neighbors” make fancy “eco-forward” rayon, but here’s how you make regular rayon. Enjoy:
- Cellulose: Production begins with processed cellulose
- Immersion: The cellulose is dissolved in caustic soda: (C6H10O5)n + nNaOH → (C6H9O4ONa)n + nH2O
- Pressing: The solution is then pressed between rollers to remove excess liquid
- White Crumb: The pressed sheets are crumbled or shredded to produce what is known as “white crumb”
- Aging: The “white crumb” is aged through exposure to oxygen
- Xanthation: The aged “white crumb” is mixed with carbon disulfide in a process known as Xanthation, the aged alkali cellulose crumbs are placed in vats and are allowed to react with carbon disulfide under controlled temperature (20 to 30 °C) to form cellulose xanthate: (C6H9O4ONa)n + nCS2 → (C6H9O4O-SC-SNa)n
- Yellow Crumb: Xanthation changes the chemical makeup of the cellulose mixture and the resulting product is now called “yellow crumb”
- Viscose: The “yellow crumb” is dissolved in a caustic solution to form viscose
- Ripening: The viscose is set to stand for a period of time, allowing it to ripen: (C6H9O4O-SC-SNa)n + nH2O → (C6H10O5)n + nCS2 + nNaOH
- Filtering: After ripening, the viscose is filtered to remove any undissolved particles
- Degassing: Any bubbles of air are pressed from the viscose in a degassing process
- Extruding: The viscose solution is extruded through a spinneret, which resembles a shower head with many small holes
- Acid Bath: As the viscose exits the spinneret, it lands in a bath of sulfuric acid, resulting in the formation of rayon filaments: (C6H9O4O-SC-SNa)n + ½nH2SO4 → (C6H10O5)n + nCS2 + ½nNa2SO4
