由淀粉获得经济有效的纺织品

通过再生资源制得的材料的经济有效性、应用广泛性及生物可降解性是纺织市场考虑的关键因素。淀粉基产品满足上述这些要求,因此在服装、土工材料及卫生用纺织品等方面具有极大的应用潜力。然而,天然淀粉的热塑性不佳,不能通过熔融纺丝的方法加工成纤维。通过化学改性和将淀粉与其他生物高聚物共混是改变淀粉性能的一种创新方法,可促进淀粉的熔融加工,如使用连续加工设备实现熔融纺丝获得纤维产品。Star-Tex项目针对改性淀粉的应用,以开发应用于服装、土工材料及医疗卫生等领域的纺织产品。

Cost effective textiles from starch

Cost effective,broad availability and biodegradability of materials produced from renewable resources are the key factors demanded by the textile market. Starch-based products fulfill the listed requirements and therefore show great potential to be used for the applications such as apparel,geotextiles and hygiene textiles. However,the native starches do not show sufficient thermoplastic behavior to be processed through melt spinning into fibers. The chemical modification and blending of starch with other biopolymers is a novel approach to modify the starch properties in order to facilitate melt processing of obtained products using e.g. continuous reaction process equipment. The project “Star-Tex”is aimed at the application of starch modification and will develop textile products,which can be used in apparel,geotextile and the hygiene sector of the textile industry.
