New fabrics: Sorona bio-based fabrics. Due to heavy reliance on petroleum and petrochemical products, the clothing and textile industry is one of the most polluting industries, producing a lot of greenhouse gases every year. As a new type of fabric, Sorona bio-based fabrics are derived from nature and can achieve low-carbon green sustainability. Sorona fiber is the latest advanced polymer platform launched by DuPont in the United States in its continuous innovation. It not only gives fibers and fabrics unique properties, but also revolutionizes the use of biotechnology in chemical fiber raw materials to achieve a perfect combination of textile functions and environmental protection. What is Sorona bio-based fabric? DuPont uses corn sugar fermentation to produce PDO required for the production of Sorona. Glucose is obtained from corn, and PDO is fermented to produce PDO under the action of genetically modified bacteria. PDO is purified and dehydrated by distillation. At this time, PDO looks like a clear and slightly viscous liquid. PTA (terephthalic acid) is added, and after reaction, SORONA slices are made to produce Sorona fiber. Fabrics mainly used Fibers made of Sorona can be blended or interwoven with any natural or synthetic fiber, even elastic fiber, giving the fabric an extremely soft feel, long-lasting shape retention, bright colors, excellent color fastness, good moisture absorption and perspiration wicking performance, comfortable stretch recovery, stain resistance and wrinkle resistance, etc. 1. Advantages of making knitted denim Permanently no deformation, no blistering. The surface of the cloth is flat, like woven denim. It can be washed in any way, and the silk will not break during the washing process. 2. High cost performance In terms of price, if only the raw materials are calculated, the price of Sorona's knitted denim will not increase.
