ABSTRACT

In recent years, the use of natural fibers has become highly popular in industrial textile applications. Typha domingensis (TD), a naturally growing plant under wetland conditions characterized by its high-quality leaf and seed fibers. An attempt was made to extract and characterize fibers from its leaves and seeds by water retting. The fibers obtained from the leaves were continuous, more than 0.9 m long, possess high tensile strength and modulus whereas, seed fibers were feathery and porous. The morphological, mechanical, chemical properties, and crystalline structure of both the fibers were analyzed. The scanning electron microscopic studies showed that typha fiber surface is smooth, fine, and circular in cross-section. The crystalline and chemical properties were very close to that of cellulosic fibers. This research has shown the possibility of using biodegradable TD leaf and TD seed fibers in the manufacturing of technical textiles and composites.

摘要

近年来，天然纤维的使用在工业纺织品应用中变得非常流行。香蒲(TD)，一种在湿地条件下自然生长的植物，其特点是其优质的叶子和种子纤维。尝试通过水沤从其叶子和种子中提取和表征纤维。从叶子中获得的纤维是连续的，长度超过 0.9 m，具有高拉伸强度和模量，而种子纤维是羽毛状和多孔的。分析了两种纤维的形态、机械、化学性质和晶体结构。扫描电镜研究表明香蒲纤维表面光滑、细腻、截面呈圆形。结晶和化学性质非常接近纤维素纤维。这项研究表明了在制造技术纺织品和复合材料中使用可生物降解的 TD 叶和 TD 种子纤维的可能性。
