Sorona, Chinese Sorona, Sorona polymer is composed of 1,3-propanediol (PDO) and PTA (or DMT) is made of two main raw materials. Among them, PDO is its key raw material, accounting for 37% of the total raw materials. PDO can be made through petrochemical processes, and DuPont in the United States has successfully used the method of corn sugar fermentation to efficiently make the PDO required for the production of Sorona, thus revolutionizing the field of chemical fibers and injecting a new concept of environmental protection.
Glucose is obtained from corn and fermented to produce PDO (1, 3 propylene glycol), which is purified and dehydrated by distillation of PDO. At this time, PDO looks like a clear and slightly viscous liquid. Then add PTA (terephthalic acid), and after the reaction, perform SORONA slicing to obtain SORONA fiber.
SORONA polymer produced using biochemical methods has the following triple environmental value
1 37% of the raw materials come from natural renewable resources instead of petrochemical raw materials, thereby reducing dependence on petroleum resources;
2 Same output Sorona polymer, compared with nylon polymers based on petrochemical raw materials, Sorona? consumes 30% less energy in making than the latter;
3 Sorona polymer emits 63% less carbon dioxide (greenhouse effect gas) than nylon polymers based on petrochemical raw materials for the same output.
DuPont Sorona can give fibers and fabrics a soft feel, comfortable stretch and recovery, easy dyeability of boiling dyeing at normal temperature and pressure, and bright and lasting color. color, as well as chlorine/UV resistance, stain resistance and easy care properties, and can be used in the development of a wide range of clothing fabrics: from light underwear to thick outerwear. This characteristic stems from its unique molecular structure: a semi-crystalline molecular structure with distinct links. When a molecule is stressed, strain first occurs in the low-molecular region of the crystal. After the external force is removed, the crystal structure locks, allowing it to completely return to its original shape.
Sorona’s fiber licensed manufacturers can produce high-quality fiber products in various specifications. Including short fibers, bi-component fibers, single-component fibers, special-shaped cross-section fibers and moisture-wicking fibers. A variety of filament or staple fibers in various deniers allows fabric mills to design and produce a wide range of fabrics – from lightweight lining fabrics, UV-resistant swimwear and comfortable ready-to-wear, to thick polar fabrics and stylish outerwear. Use Sorona
The fibers made can be blended or interwoven with any natural or synthetic fiber, even elastic fiber, thus giving the fabric an extremely soft feel, long-lasting shape retention, bright colors, excellent color fastness, good moisture absorption and perspiration properties, Comfortable stretch recovery, stain resistance and wrinkle resistance, etc.
