Study on the Characteristics of Cottonized Indian Industrial Hemp Fibers

ABSTRACT

Hemp fiber is one of the natural bast fibers, mainly obtained from the hemp plant with the species of Cannabis sativa(L). In recent time, hemp fibers have received wide applicability in composite materials on account of their sustainability and low density compared with manmade fibers. Hemp fibers also have inherent mechanical, acoustic, thermal, and physical properties. Industrial hemp is a genetically modified form of C. sativa(L) plant containing low THC (Δ-9 Tetrahydrocannabinol) value of below 0.3%. In this study, an attempt has been made to cottonization of Indian industrial hemp fiber. The fibers were given an alkali treatment for the removal of non-cellulosic content. Three different levels of concentration, time and temperature were selected for the treatments on the Box-Behnken response surface design principle. The effect of alkali treatment on mechanical properties viz; length, strength, and weight loss and physical properties viz; diameter, surface were analyzed. This process has eliminated the Indian traditional tedious water retting and time-consuming process used on Hemp fibers. The resultant fiber obtained from the proposed process is textile grade quality and spinnable by the cotton dry spinning system. The effect of alkali treatment on the mechanical and physical properties was found significant.

摘要

大麻纤维是一种天然韧皮纤维,主要来源于大麻属植物大麻(L). 近年来,大麻纤维由于其可持续性和与人造纤维相比的低密度,在复合材料中得到了广泛的应用. 大麻纤维还具有固有的机械、声学、;热学和物理性能. 工业大麻是一种转基因大麻植物,其THC (Δ-9四氢大麻酚)值低于0.3%. 在这项研究中,对印度工业大麻纤维的棉化进行了尝试. 对纤维进行碱处理以去除非纤维素含量. 根据Box-Behnken响应面设计原则,选择三种不同浓度、;时间和温度水平进行处理. 碱处理对机械性能的影响,即:;长度、;强度、;重量损失和物理性能,即:;对直径、;表面进行了分析. 这一工艺消除了印度传统的麻纤维上繁琐的水脱胶和耗时的工艺. 从拟定工艺中获得的合成纤维具有纺织级质量,可通过棉干纺系统进行纺纱. 碱处理对材料的力学和物理性能有显著影响.
