Abstract

This paper reports the structure and properties of novel long natural cellulose fibers obtained from rice straw. Rice straw fibers have 64% cellulose with 63% crystalline cellulose, strength of 3.5 g/denier (450 MPa), elongation of 2.2%, and modulus of 200 g/denier (26 GPa), similar to that of linen fibers. The rice straw fibers reported here have better properties than any other natural cellulose fiber obtained from an agricultural byproduct. With a worldwide annual availability of 580 million tons, rice straw is an annually renewable, abundant, and cheap source for natural cellulose fibers. Using rice straw for high-value fibrous applications will help to add value to the rice crops, provide a sustainable resource for fibers, and also benefit the environment.

摘要

本文报道了从稻草中获得的新型长天然纤维素纤维的结构与性能。稻草纤维含有64%的纤维素，其中结晶纤维素占63%，强度为3.5克/旦（450兆帕），伸长率为2.2%，模量为200克/旦（26吉帕），与亚麻纤维相似。这里报道的稻草纤维比从农业副产品中获得的任何其他天然纤维素纤维都具有更好的性能。稻草全球年产量达5.8亿吨，是天然纤维素纤维每年可再生、丰富且廉价的来源。将稻草用于高价值纤维应用将有助于提升水稻作物的价值，为纤维提供可持续资源，同时也有利于环境。
