The only sure way to tell what anything is made of is with a mass spectrometer.Originally they were prohibitively expensive,in the millions of dollars,but they've gotten to the point where they are affordable.Many older but functional units are available for sale to the general public:
Plasma quad 2 for only 6k:http://www.medwow.com/used-mass-spec...543260304.item
Labx has tons of them: http://www.labx.com/v2/newad.cfm?catid=12
This one is a portable self contained system,not sure of the price:http://www.kore.co.uk/ms-200.htm
This one in very compact and the base unit is only $600!: http://www.labx.com/v2/adsearch/deta...?adnumb=431314
These are amazingly tiny:http://www.labx.com/v2/adsearch/deta...?adnumb=431633
The cheapest way is to pay someplace that has one to analyze a sample,I've seen places that will test a sample for as low as $10.Most universities and decent medical labs have one,if you know someone who works there they could hook you up.I had a girlfriend who worked at WHOI who would test anything I wanted but she quit because her boss,Robert Ballard,was a douchebag(to work for).Of course it can analyze anything,not just fabric,and the possibilities are endless.
