壳聚糖可持续涂层织物

Coating textiles sustainably with chitosan

将生物聚合物壳聚糖涂覆在纺织品上,通过结合疏水分子使纺织品具有拒水功能,可以取代目前用于纺织品后整理的有毒的石油基物质。在过去几年中,Fraunhofer界面工程和生物技术研究所IGB以及HydroFichi项目的合作伙伴研究了如何做到这一点,已经开发出一种技术,即利用生物技术工艺和壳聚糖为纤维提供所需的特性。

Textiles can be coated with the biopolymer chitosan and thus made water-repellent by binding hydrophobic molecules.The good thing is that this can also replace toxic and petroleum-based substances that are currently used for textile finishing.In the last few years,the Fraunhofer Institute for Interfacial Engineering and Biotechnology IGB and partners in the HydroFichi project have researched how this can be done:a technology has been developed to provide fibers with the desired properties using biotechnological processes and chitosan.
