We don't really use silk the way we did. Cotton is easier to produce, synthetics are cheaper.
But that might change. Researchers have found a way to treat silk that reflects 95% of sunlight. This could be used for cooling clothing (more important with climate change) and to make sun shirts and the like out of.
Of course, the question is how expensive this is going to be...but a shirt that keeps your skin about 8 degrees Celsius cooler? Sign me up.
