Synthetic filament tow
In plain English
This category covers synthetic filament tow made from various man-made materials. The items are sorted by their specific chemical composition, such as nylon, polyamides, polyesters, acrylics, or polypropylene. Aramid fibers are distinguished from other polyamides within the nylon group. Any other synthetic materials not listed in the previous categories fall into the final group.
