Thermal, Chemical and Mechanical Properties of Regenerated Bacterial Cellulose Coated Cotton Fabric

ABSTRACT

Bacterial cellulose is a raw material that is used in many industrial areas such as textile due to its properties and an alternative to plant cellulose whose usage is increasing day by day. In this research, dissolved bacterial cellulose was used as a coating material. After the coating process, samples were immersed in three different coagulation baths to provide regeneration of the coated material. TGA, FTIR, SEM-EDX, air permeability, tensile test, thermal comfort (alambeta), and water vapor transmission (permetest) analyses were carried out to compare the mechanical, chemical, and thermal properties between raw fabric and treated fabrics. Because of chemical analysis, it was observed that the structures are similar to each other. In terms of thermal stability, it has been determined that the samples that have been coated are more durable than the raw fabric. The tensile test revealed that there was a decrease between 15.05% and 41,62% in the strength of coated materials. According to the results of air permeability, alambeta, and permetest, a decrease in air permeability values, an increase in relative water vapor permeability, and thermal conductivity values were observed with the increase of the remaining coating material in the fabric.

摘要

细菌纤维素是一种用于纺织等许多工业领域的原材料,由于其特性,它是植物纤维素的替代品,植物纤维素的使用量日益增加. 在本研究中,溶解的细菌纤维素被用作涂层材料. 涂层工艺完成后,将样品浸入三种不同的凝固浴中,以提供涂层材料的再生. 通过TGA、FTIR、SEM-EDX、透气性、拉伸试验、热舒适性(alambeta)和水蒸气透过率(permetest)分析,比较了原织物和处理后织物的机械、化学和热性能. 由于化学分析,观察到这些结构彼此相似. 就热稳定性而言,已确定已涂覆的样品比原织物更耐用. 拉伸试验表明,涂层材料的强度下降了15.05%至41.62%. 根据透气性、alambeta和permetest的结果,观察到随着织物中剩余涂层材料的增加,透气性值降低,相对水蒸气透气性和导热性值增加.
