竹、麻纤维的导湿性、染色性比较 总被引:2,自引:0,他引:2
竹纤维是一种新型环保的纤维,与麻纤维同属纤维素纤维.竹纤维表面有较多的裂缝,截面有中腔孔径,其化学和物理性能易受药剂等外界因素的影响,其可及区的增加更有利于染料上染.竹纤维可用染麻等纤维素类染料进行染色.文章分析了竹、麻纤维的吸湿、导湿性能,研究了温度、元明粉、固色剂等因素对纤维染色性能的影响;测试了黛棉丽、汽巴FN型活性染料对竹、麻织物染色的上染率和固着率,结果表明竹纤维的导湿性与染色性比麻纤维更好. 相似文献

The comfort characteristics of bamboo/cotton-blended knitted fabrics made from rotor-spun yarns were studied in this research work. Five different blend proportions namely 100% bamboo, 100% cotton, 50:50 cotton:bamboo, 70:30 cotton:bamboo and 30:70 cotton:bamboo were used to produce rotor-spun yarns of 30sNec. The yarn samples developed out of these different blend proportions were evaluated for yarn strength and elongation, yarn unevenness, yarn imperfections and used to produce single-jersey-knitted fabrics. All the fabric samples were dyed and finished. Fabric samples were evaluated for geometrical properties such as course/inch, wales/inch, stitch density and thickness apart from measuring comfort properties such as airpermeability, thermal conductivity, thermal resistance and water vapour permeability. The results indicated that 50/50 bamboo/cotton-blended knits have comparable fabric quality in terms of comfort properties with respect to 100% bamboo fabrics. 相似文献

以标准线性固体模型为基础,利用玻尔兹曼叠加原理对纱线在拉伸松弛过程中的力学行为进行分析,建立纱线应力松弛的理论方程。在应变一定、拉伸速度不同情况下和拉伸速度一定、不同应变条件下分别对涤/粘纱和竹浆纤维/棉纱进行拉伸应力松弛实验,求得纱线在各种情况下的应力松弛回归方程及其相关系数,理论计算和实测结果在拉伸和松弛阶段都符合得很好。实验结果表明:该模型能够很好地模拟纱线在小应变下的松弛性能;在其他条件相同的情况下,拉伸速度越大或纱线应变越大,纱线的松弛时间越短,松弛现象越明显。 相似文献

竹原纤维织物芯吸效应的测试研究 总被引:1,自引:0,他引:1
为进一步了解竹原纤维织物的导湿性能,研究分析了竹原纤维的化学组成和结构特点,选取棉织物、苎麻织物、精纺毛织物与竹原纤维织物,对它们的芯吸效应进行了测试、比较,并从纤维内部结构特点分析了影响芯吸效应的因素.结果表明:竹原纤维织物相对于棉织物、苎麻织物和毛织物而言,具有更加优良的导湿性能. 相似文献

Ultraviolet protection factor (UPF) of fabrics made of 100% cotton and 100% bamboo viscose yarns were studied and a comparative analysis carried out using curve fitting technique. Bamboo viscose fabrics showed higher shrinkage, cover percentage, areal density and UPF compared to its cotton counterpart woven with identical yarn counts and fabric sett. However, the predictive model of cotton fabric UPF using fabric areal density as the input was able to estimate the UPF of bamboo viscose fabrics with very good accuracy. Furthermore, the 100% cotton and 100% bamboo viscose fabrics showed the same UPF if their cover percentage and areal density is similar. It is inferred from the analysis that the apparently higher UPF of bamboo viscose fabrics can be attributed to their higher cover percentage and areal density instead of bamboo’s inherent UV protective property which has been claimed in various literatures. 相似文献
