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

细菌纤维素是一种原材料，由于其特性而被用于纺织等许多工业领域，并且是植物纤维素的替代品，其使用量日益增加。在这项研究中，溶解的细菌纤维素被用作涂层材料。在涂覆过程之后，将样品浸入三种不同的凝固浴中以提供涂覆材料的再生。进行了 TGA、FTIR、SEM-EDX、透气性、拉伸试验、热舒适性 (alambeta) 和水蒸气透过性 (permetest) 分析，以比较原料织物和处理过的织物之间的机械、化学和热性能。由于化学分析，观察到结构彼此相似。在热稳定性方面，已经确定，经过涂层处理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%。根据透气度、alambeta和permetest的结果，随着织物中剩余涂层材料的增加，观察到透气度值下降，相对水蒸气渗透率和热导率值增加。
