竹纤维的表面化学特性及与棉纤维的比较

Comparisons of the Surface Properties of Bamboo Fiber and a Comparison with Cotton Linter Fiber

报道了竹纤维的表面化学性能,如:表面能、Lifshitz-vanderWaals力、Lewis酸性和碱性。为了认识竹纤维的表面性能,同时还对棉纤维的表面性能进行了测试以作对比。结果表明,竹纤维的表面性能与棉纤维基本相同,但两者具有一个非常明显的差异,即前者的Lewis酸性是后者的一倍。这个发现极好地解释了人体皮肤在夏天接触竹纤维时感到舒适的现象。研究还指出,竹纤维的取向性略差于棉纤维,这可能会导致竹纤维的柔软性、面料性能略逊于棉纤维。

This paper reported the surface properties of bamboo fiber, e.g. the surface free energy, the Lifshitz-van der Waals force and Lewis acid and base component. In order to understand the surface properties for bamboo fiber, cotton linter fiber was also employed to determine the same parameters as that of bamboo fiber. A comparison of these two fibers shows that the surface free energy for both is similarly. However, one difference of interest observed is that the Lewis acid component for bamboo fiber is greater almost double comparing to cotton linter fiber. Therefore, it perfectly explained the phenomenon why people touch bamboo fiber in summer would be comfortable than that of touching cotton fiber. Additionally, based on the polarity and orientation values, this paper indicated that bamboo fiber might not be good as cotton linter fiber for textile production.
