Increasing interest in bio-based polymers and fibers has led to the development of several alternatives to conventional plastics and fibers made of these materials. Biopolymer fibers can be made from renewable, environmentally friendly resources and can be fully biodegradable. Biogenic resources with a high content of carbohydrates such as starch-containing plants have huge potentials to substitute conventional synthetic plastics in a number of applications. Much literature is available on the production and modification of starch-based fibers and blends of starch with other polymers. Chemistry and structure-property relationships of starch show that it can be used as an attractive source of raw material which can be exploited for conversion into a number of high-value bio-based products. In this review, possible spinning techniques for the development of virgin starch or starch/polymer blend fibers and their products are discussed. Beneficiation of starch for the development of bio-based fibers can result in the sustainable replacement of oil-based high-value materials with cost-effective, environmentally friendly, and abundant products.
对生物基聚合物和纤维的兴趣日益浓厚，促使人们开发出了几种替代传统塑料以及由这些材料制成的纤维的产品。生物聚合物纤维可由可再生、环境友好的资源制成，并且可以完全生物降解。诸如含淀粉植物等富含碳水化合物的生物资源在许多应用中具有巨大潜力，可替代传统合成塑料。关于淀粉基纤维以及淀粉与其他聚合物共混物的生产和改性，已有大量文献。淀粉的化学性质和结构-性能关系表明，它可以作为一种有吸引力的原料来源，用于转化为多种高价值生物基产品。在本综述中，讨论了开发原生淀粉或淀粉/聚合物共混纤维及其产品可能采用的纺丝技术。为开发生物基纤维而对淀粉进行的精选，可以用具有成本效益、环境友好且储量丰富的产品可持续地替代石油基高价值材料。
