ThermasilkÔ Construction Silk is the only natural fiber in the world that can go from a raw state into a finished garment without processing. Silk is radiant and lustrous. Like a fine pearl, silk is composed of layers of protein built up to give it a pearly sheen. Silk is truly a miracle of nature. For silk production to take place, the silk cocoons are placed in a liquid to loosen the "glue" which binds the silk filament around the cocoon. Mechanical fingers then "unwind" a continuous, unbroken filaments of silk thread from each cocoon. Fourteen filaments are twisted together to form one "end". Three "ends" of silk filaments are then twisted together to form 1 strand of silk yarn or a total of 42 filaments from 42 silk cocoons.
