Somalor-Unique Molecular StructureSorona polymer, used for Somalor is a kind of polymer similar as PET and PBT. It is polymerized by 1, 3-propanediol and PTA. Its molecular structure is as shown in Figure. The molecular chain of Somalor fiber is a Z-shaped structure. When stress is exerted on the molecular, strain deformation occurs firstly in its crystalline, lower modulus regions. As stress is released, the crystalline structure locks in, allowing a complete recovery to the initial shape. In conjunction with this distinctive characteristic, Somalor fiber offers additional advantages over both polyester (PET) and nylon. It has a softer feel and supports easier, more versatile dyeability with excellent wash fastness and UV resistance. Somalor fiber, with these specialties in all, has the potential to lead the market.
