Gray Area: Kelp is On the Way

In the search for interesting sustainable fabrics that look and feel good, I often come across blends that offer one technological and environmental marvel adulterated with something altogether less appealing. Take the seaweed-blend shirting shown here on Lykke. Seaweed is micronized and combined with a substrate of lyocell (wood pulp cellulose, which is produced very cleanly) to form fiber. It doesn’t retain heat, so it’s cool against the skin in the summer. Its manufacturers also claim that the marine minerals and other nutrients absorb into the skin, protecting it from free radicals and “creating a sense of well-being.” The catch? In this fabric, the fiber comes blended with 75 percent conventional cotton, which, for those of you who haven’t heard, is more or less poisoning us all.

I decided to make the dress, if only to raise awareness of a new, interesting natural textile technology. Algae is a promising substance in all sorts of fields, like fuel (jets have flown on algal oil blends to much recent fanfare) and on-site CO2 absorption at power plants. Although, as it turns out, only the organic cotton gauze version of the dress is going into production (look for it at Steven Alan this spring).
Still, and I hope I’m not going to get in trouble for saying this, I wonder about the “well-being” angle. It’s all well and good if a fabric feels nice and comes from an abundant self-generating source, but I’m curious about the actual structure of the fiber. If it turns out the seaweed is only there to dose the fabric with vitamins, does that violate the principle of sustainability?
What do you think?
