Thermo-physiological Comfort of Woven Fabrics Made from Different Cellulosic Yarns

ABSTRACT

Cellulose is the most abundant substance existing in the form of plants on the earth. These fibers are obtained either directly or indirectly from the seed, leaves, stem, or wood of plants. Cellulosic fibers are preferred for apparels owing to their abundance, ease of processing, biodegradation, and compatible with the human body in terms of better moisture management, thermal regulation, and tactile comfort. In this study, woven fabric made of four different cellulosic yarns, i.e. cotton, bamboo, tencel, and viscose were produced, and their thermo-physiological comfort properties were compared. The linear density of yarns, and thread density and weave structure (3/1 twill) of all the fabrics were kept constant on the weaving machine. Air permeability, thermal resistance, and moisture management tests were carried out to analyze their thermo-physiological comfort properties. The results showed that cotton fabric showed higher air permeability and thermal resistance as compared to other cellulosic fabrics. Whereas the moisture management properties of tencel fabric were superior to the rest of cellulosic fabrics. Moreover, the effect of cellulosic materials on air permeability and moisture management properties of the woven fabrics was found statistically significant.

摘要

纤维素是地球上以植物形式存在的最丰富的物质. 这些纤维可以直接或间 接地从植物的种子、叶子、茎或木材中获得. 纤维素纤维因其丰富、易于 加工、可生物降解、与人体相容, 具有更好的水分管理、热调节和触觉舒 适性, 因此是服装的首选. 以棉、竹、tencel、粘胶4种不同的纤维素纱线 为原料, 制备了织物, 并对织物的热生理舒适性进行了比较. 纱线线密度、 线密度和组织结构(3/1斜纹)在织机上保持不变. 通过透气性、热阻和湿 度管理试验, 分析了它们的热生理舒适性. 结果表明, 与其他纤维素织物相 比, 棉织物具有较高的透气性和耐热性. Tencel织物的吸湿性能优于其它纤 维素织物. 此外, 纤维素材料对机织物透气性和吸湿性的影响具有统计学意 义.
