Sorona, as a biobased polymer material, has been gradually expanding its application in the textile and clothing industry. This fiber was developed by DuPont of the United States. The core raw material consists of 37% plant-based components, derived from 1,3-propanediol produced by fermentation of corn sugar. Understanding the material properties and actual performance of Sorona can help fabric developers and clothing brands use this raw material more appropriately.
The molecular structure of Sorona directly affects its performance. The molecular chains of Sorona have a spring-like semi-crystalline structure. When stretched, the deformation occurs in specific areas of the crystal, and the original state can be restored after the external force is removed. This structural characteristic enables Sorona fibers to have a good elasticity recovery rate. Data shows that after being stretched by 300%, it can recover more than 92%. Compared with spandex, Sorona has higher durability and is less likely to lose elasticity after long-term use.
In terms of fabric performance, Sorona exhibits a variety of characteristics. It has a soft and smooth texture, similar to that of cotton fabric, while also possessing the strength and wrinkle-resistance of polyester. The dyeing performance is excellent, allowing for boiling dyeing at normal temperature and pressure. The color vividness and color fastness can reach a good level. The moisture absorption and sweat-wicking function is also one of its features, enabling the rapid evaporation of sweat and maintaining dryness during wear. The chlorine bleach resistance and UV resistance properties make it suitable for special categories such as swimwear.
Sorona's application scope covers various types of clothing. In the sportswear and casual wear sector, Sorona is commonly used in items such as T-shirts and jackets, providing elastic shaping functionality. The fabric does not sag easily after being stretched. In the household products category, it is also applied to items like carpets and artificial fur. Sorona can also be blended or interwoven with fibers such as cotton, wool, and polyester to develop a variety of products such as knitted jeans, underwear, and workwear.
