Sorona Polymer is the latest advanced polymer platform in the continuous innovation of the United States DuPont in its sixty years of fiber raw materials. It not only gives a unique performance of fibers and fabrics, but also uses biotechnology in the chemical fiber feedstock to seek intake in textile function and environmental protection.
SORONA, Chinese Sorina, SORONA polymer is made of two main raw materials of 1,3-propanediol (PDO) and PTA (or DMT). Among them, PDO is its key raw material, accounting for 37% of total raw materials. PDO can be made by petrochemical process, and US DuPont successfully utilizes cornose fermentation to efficiently produce PDO required to produce Sorona, thus injecting environmentally friendly new concepts into chemical fiber.
Glucose was obtained from corn, and the PDO (1,3 propanediol) was produced by fermentation under the action of genetically modified bacteria, and the Draminated PDO was purified and dehydrated. At this time, the PDO looks a clear and slightly viscous liquid. The addition of PTA (terephthalic acid), after the reaction, SORONA slice can be made to produce Sorona fibers.
The SORONA polymer produced by the biochemical method has the following triple environmental value
1 37% of raw materials come from natural renewable resources, rather than petrochemical raw materials, thereby reducing dependence on oil resources;
2 Sorona polymers of the same yield, compared to the nylon polymers based on petrified raw materials, Sorona is consumed less than 30% more energy than the latter;
3 SORONA polymers of the same yield, Sorona? Sorona is less exclusively from 63% of carbon dioxide (i.e., greenhouse effector) than the latter.
DuPont Sorona can give fiber and fabric soft feel, comfortable stretching and recovery, alternatively constant pressure boiling dye, gorgeous and lasting colors, and chlorine / low-resistance and anti-staining characteristics, and It is widely used in the development of various types of clothing fabrics: from a thin underwear to thick jacket. This feature is derived from its unique molecular structure: a semi-crystalline molecular structure that is obvious. When the molecule is stressed, the strain first occurs at the low molecular region of the crystal, and after the external force is removed, the crystallization structure is locked to make it completely restored.
Sorona's fiber franchiseer can produce high-quality fiber products of various specifications. Including short fibers, two-component fibers, single-component fibers, shaped cross-sectional fibers, and moisture absorption. Various filaments or short fibers can make the fabric factory design and produce all kinds of fabrics - from a light lining cloth, the ultraviolet swimsuit and comfortable garment, to the thick shake fabric and stylish jacket. The fibers made of Sorona can be blended with any natural or synthetic fibers, even elastic fibers, thus impart extremely soft feel, long-lasting conformality, bright colors, excellent color fastness, good moisture absorption Performance, comfortable stretching and stain resistance and wrinkle performance, etc.
