The type of fabric was originated by a man called Alfred Shaheen. The name of his fabric company was Surf ‘n Sand Handprints. He was born in New Jersey, the son of a Lebanese immigrant but moved to Hawaii where he built his business and trained a staff that continues to maintain the legacy throughout Hawaii’s textile trade.
His story is really interesting. While the motifs he used in his prints were drawn from traditional sources, he was really into historical research and ethnic artistic heritage, it was his hands on entrepreneurial skills and his innovative mind that took it to new levels and made him the collectible label that he is today. The company still has a website where you can read some of the history of the company. There are photos of the printing plant he used to make not only the fabrics, but the garments themselves.
One of his main innovations was the metallic dyes that you are talking about. He made the dyes in over 100 colors but (according to http://www.causeafrockus.com/2013/11/vintage-hawaiian-prints/ , it was the gold, silver and copper that were the most popular. There are many metallic prints on the market now but he was one of the first and he focused on making a quality product that would hold up to the harsh rays of the sun and not fade or wash off. These prints have really stood the test of time and you can see his items being sold and colliected on Ebay, Etsy and many vintage sites.
I don’t think the fabric has a particular name. Cotton was used and rayon also, but the name you could search under is Alfred Shaheen or Surf ‘n Sand Handprints.
Elvis wore an Alfred Shaheen shirt in Blue Hawaii. Tom Selleck wore a red Shaheen shirt in Magnum, P.I..
