【摘要】 香蕉纤维是一种新型的天然纤维素纤维,由于具有天然环保的优势在目前的新材料开发中非常热门。我国是世界香蕉的主产国之一,每年香蕉产量有五六百万吨,为香蕉纤维的开发和利用提供了非常丰富的资源条件。香蕉纤维的开发和利用也进行到了服装生产的阶段,为消费者增加了纺织品的花色品种,同样也带来了可观的经济效益。因此,了解香蕉纤维的结构特征、基本性能与鉴别方法是将来纺织生产中必需解决的问题。本文选用国内主要生产香蕉纤维产品的苏州圣竹家纺有限公司提供的香蕉工艺纤维为主要研究对象,通过显微投影、红外光谱、化学溶解以及纤维强力测试的方法讨论与分析了香蕉纤维的形态结构与基本性能。实验结果表明,香蕉纤维的表面具有横节竖纹,截面为腰圆形,内有裂纹存在,与苎麻纤维相似；具有较为典型的纤维素纤维的化学溶解特征；纤维强力测试表明香蕉纤维具有较高的干湿强度,其中湿态强度比干态强度要高出达50%。在认识纤维形态结构与基本性能的基础上,从定性与定量两方面对香蕉纤维的鉴别技术进行了初步探讨,定性鉴别的研究选用香蕉纤维与苎麻、亚麻纤维进行对比,通过纤维形态与红外光谱的分析,提出了一个切实可行的香蕉纤维的定性鉴别方法,即香蕉纤维的鉴别可以同时从两条路径出发同时测试纤维的形态结构与红外光谱图,当两条路径全部符合时即可判定该纤维为香蕉纤维；在定量鉴别方法的探讨中,参照国家标准GB/T2910.4-2009规定的方法,以香蕉纤维与羊毛纤维混纺的试样鉴别为例,介绍了定量分析方法的溶剂选择与重量修正系数的测定及计算,以实验验证,该办法测试出来的结果准确度符合标准的要求。更多还原

【Abstract】 Banana fiber is a new natural, cellulosic fiber which is very popular in development of new material at present because of its natural environmental advantages. Our country is one of the world production of bananas, annual output of bananas is about 5 million to 6 million ton which provides a very rich resource conditions to develop and apply banana fibers. The development and application of banana fibers have reached the cloth stages which add the designs of textiles for consumers and also bring remarkable economic benefits. So it is necessary to know the structure properties, common performance and identification method of banana fibers to prepare for subsequent textile processing.This article selects banana fiber goods as researching ones which produced by Su Zhou Shengzu domestic textiles limited company to discuss and analyze the morphological structure and common performance of banana fibers by microscope projection, infrared spectrum, chemical dissolving and testing fiber strength, etc. It is indicated that the appearance of banana fibers have some crossed marks and vertical lines, its cross-section is oral. Its inner cracks are similar to the ramie ones. Also banana fibers have typical dissolution characteristic of cellulosic fibers. From the strength testing results, it is indicated that banana fibers have higher dry-and wet-strength, of these wet-strength is fifty percent higher than dry-strength. Based on knowing the morphological structure and common performance of fibers, preliminary discussion of bananas fibers is carried out by using the qualitative and quantitative identification techniques. The qualitative study refers to comparing banana fibers with ramie and flax fibers. By analyzing the morphological structure and infrared spectrum of fibers, a practical qualitative identification is presented, i.e. the identification of banana fibers may be carried out by concurrent testing morphological structure and infrared spectrum of fibers. When two ways show no difference, it can be determined that this fiber is banana fiber. The quantitative study refers to the national standard GB/T GB/T2910.4-2009, taking the banana fiber and wool fiber blends as testing specimen to introduce the quantitative analysis method to select solvent, determine and calculate the weight correction coefficient. From the experiment, it is verified that the accuracy of the testing results meet the standard required.更多还原
