Abstract

In this research, cotton fabrics were treated with carboxylated chitosan, loaded by the pad-dry-cure method for investigating the absorption of heavy metals and the Ultraviolet (UV) protection properties of fabric samples. For this purpose, chitosan-treated cotton fabrics were soaked in CuSO4 solution to investigate the rate of heavy metal absorption. The surface morphology of cotton fabrics was investigated using Scanning electron microscopy (SEM) analysis. Inductively coupled Plasma Spectroscopy (ICP) analysis was employed to examine the amount of heavy metals' absorption upon chitosan-treated cotton fabrics. Besides, reflection and transmission spectrophotometry analyses were used to examine the optical properties of cotton fabrics. The results show a noticeable increase in copper absorption by increasing the amount of chitosan. The maximum absorption of Cu belongs to the %6 chitosan-treated sample by 7357.6 PPM, equal to %7.35. The more concentration of chitosan in the fibre causes a higher rate of UV protection. Therefore, the chitosan-treated cotton fabrics examined in this work can be used for various water filtration purposes, notably to eliminate toxic metals. Also, It can be used as a wearable textile for protecting against harmful UV rays.

壳聚糖对棉机织物金属吸收和紫外线防护性能的影响

本研究采用羧化壳聚糖对棉织物进行处理，采用衬垫干燥固化法对织物样品的重金属吸收和紫外线防护性能进行了研究。为此，将壳聚糖处理的棉织物浸泡在硫酸铜溶液中，研究其对重金属的吸收速率。用扫描电子显微镜（SEM）分析了棉织物的表面形貌。采用电感耦合等离子体光谱法（ICP）分析了壳聚糖处理棉织物对重金属的吸收量。此外，还用反射和透射分光光度计分析了棉织物的光学性能。结果表明，随着壳聚糖用量的增加，铜吸收率显著提高。Cu的最大吸收属于用7357.6PPM处理的%6壳聚糖样品，相当于%7.35。纤维中壳聚糖浓度越高，紫外线防护率越高。因此，本工作中检测的壳聚糖处理的棉织物可用于各种水过滤目的，尤其是用于消除有毒金属。此外，它还可以作为一种可穿戴的纺织品来抵御有害的紫外线。
