Filament extrusion and twisting (for nylon)
1 To make floss from nylon, nylon salt is polymerized and the resulting polymer is poured out as a ribbon. Next, it is cut into small chips, flakes, or pellets. These are blended, remelted, and pumped through spinnerets to form filaments. When the nylon cools, the filaments solidify and regather to form a yarn. The ends of the filaments are combined to create one strand of floss. Correctly twisting the nylon is a vital part of this process; the turns average between 2.5 and 3.5 per inch. Twisting adds strength to the floss as well as greatly reducing fraying or breaking.
Since floss consists of many filaments, it can be produced in different "decitexes. " Decitex is defined as the weight of 10,000 meters of unwaxed nylon in grams. Floss is also measured by "Denier. " Denier is defined as the weight of 9,000 meters of uncoated floss in grams. There is a direct correlation between the numerical value of the decitex or denier and the thickness of the strand of floss: if this value increases, the thickness of the strand also increases.
