PTT is also called elastic polyester, but it does not contain any spandex components. Dupont also calls it Sorona. The cost of the raw material PDO, 1,3 propylene glycol, is higher, and the cost is now reduced by refining it from corn. Due to the introduction of PDO, there is a methylene ch2- on the fiber structure, so that the fiber is spiral, which is the reason why PTT fiber is elastic. PTT fiber has the characteristics of polyester, nylon and acrylic. In addition to good anti-fouling performance, PTT fiber is easy to dye, soft to feel and elastic, and its elongation is as good as spandex fiber. Compared with elastic fiber spandex, PTT fiber is easier to process and very suitable for textile and clothing fabrics. In addition, PTT also has the characteristics of dry, crisp, superior dyeing fastness, sun fastness and stain resistance. Widely used, suitable for the production of carpets, fashion, socks, underwear, sportswear and swimwear. Product specifications are
75D/36F, 150D/72F.
