A study on the thermophysiological and tactile comfort properties of silk/lyocell blended fabrics

ABSTRACT Certain investigations on the thermophysiological and tactile comfort properties of silk/lyocell blended fabrics have been carried out. A series of yarns were produced as 100% silk (S 100), 75% silk and 25% lyocell (S/L 75:25), 50% silk and 50% lyocell (S/L 50:50), 25% silk and 75% lyocell (S/L 25:75) and 100% lyocell (L 100) and converted to woven fabrics keeping the same fabric set. FTIR study on silk, lyocell and silk/lyocell blended fabrics show the characteristic functional groups for the respective fabrics. The effects of blend compositions on thermophysiological and tactile comfort properties were examined and the results show that thermal resistance of the fabrics containing silk has a higher value in comparison with lyocell-rich blends. Water vapour permeability, absorbency and wickability for lyocell and lyocell-rich blends are found to be superior as compared to 100% silk fabrics. With respect to drape, bending length and crease recovery the lyocell rich fabrics are good in comparison with 100% silk fabrics. The results are discussed using one way ANOVA with 5% significant level.

摘要 本研究针对真丝/莱赛尔（lyocell）混纺织物的热生理与触觉舒适性能开展了相关探究。制备了一系列纱线，包括100%真丝（S 100）、75%真丝与25%莱赛尔（S/L 75:25）、50%真丝与50%莱赛尔（S/L 50:50）、25%真丝与75%莱赛尔（S/L 25:75）以及100%莱赛尔（L 100），并以统一的织物规格加工为机织面料。对真丝、莱赛尔及真丝/莱赛尔混纺织物开展的傅里叶变换红外光谱（FTIR）分析结果显示，各织物均呈现出对应材质的特征官能团。本研究探究了混纺配比对热生理与触觉舒适性能的影响，结果表明：含真丝织物的热阻高于莱赛尔占比更高的混纺织物。研究发现，莱赛尔纤维及高莱赛尔混纺织物的水蒸气透过率、吸湿性与芯吸性能均优于100%真丝织物。在悬垂性、弯曲长度与折皱回复性方面，高莱赛尔混纺织物均优于100%真丝织物。本研究采用显著性水平为5%的单因素方差分析（one way ANOVA）对实验结果进行了讨论。
