Role of Lignin Enriched Natural Sesbania aculeata (Dhaincha) Fiber for Ultraviolet Protection and Thermal Comfort of Woven Textiles

ABSTRACT

Sesbania aculeata (Dhaincha), a lignocellulosic bast fiber, has been explored here as an ultraviolet blocker due to the presence of natural lignin of about 19% on its surface. Various woven fabrics are prepared with various dhaincha/jute-blended yarns as weft to measure ultraviolet (UV) protection ability, drying rate, and thermal conductivity. Effect of linear density of blended yarn, blend ratio, and pick density of the prepared fabrics on UV protection ability, drying rate, and thermal conductivity have been studied and optimized using 3³ Box–Behnken response surface design. The optimum level of these parameters to obtain high UV protection, high drying rate, and high thermal conductivity are reported. The UV protection factor (UPF), drying rate, and thermal conductivity of the fabric are achieved as high as 92.68, 0.3589 ml/H, and 0.185754 W/mK, respectively. The presence of lignin in jute and dhaincha fibers is evidenced by FTIR study. This research work establishes the new application of dhaincha fiber in the field of textiles for UV protection and thermal comfort.

摘要

田菁(Dhancha)是一种行话中的纤维素韧皮纤维, 由于其表面含有约19%的天然木质素, 因此被用作紫外线阻滞剂. 各种机织物采用各种达因查/黄麻混纺纱作为纬纱, 以测量紫外线(UV)防护能力、干燥速度和热导率. 采用3³-Box-Behnken响应面设计, 研究并优化了混纺纱线密度、混纺比和制备织物的拾取密度对紫外线防护能力、干燥速度和导热系数的影响. 报告了获得高紫外线防护、高干燥速率和高导热性的这些参数的最佳水平. 织物的紫外线防护系数(UPF)、干燥速率和导热系f数分别高达92.68、0.3589ml/H和0.185754w/mK. FTIR研究证明黄麻和达因查纤维中存在木质素. 这项研究工作为达因查纤维在纺织品领域的紫外线防护和热舒适性提供了新的应用.
