dimension)来描述大自然事实上任何物体的微观平面都是凹凸不平的，因而欧氏几何所描述的对象，严格来讲，在现实生活中是不存在的 分形是用来描述大自然的一门几何学，它所描述的图形可以是分数维分形的特征是整体和局部有严格的或统计意义下的自相似性描述分形的定量参数为分维，而维数的定义种类很多，如相似维数、Hausdorff维数、盒维数(box dimansion)、拓扑维数(topological dimension)等，需要随研究对象的改变来选择研究表明，分形在自然界中随处可见，例如，曲折而不规则的闪电路径，弯曲复杂的海岸线形状、密如蛛网的人体血管系统、变换不定的宇宙星云分布以及材料的组织生长、准晶态的晶体结构、材料的损伤等等从地理学、生物学到物理学、化学甚至社会科学都普遍存在分形现象分形理论在高分子科学中的应用研究也有很多文献报道，例如分形理论与各种现代分析手段相结合，已用于研究高分子的链结构、结晶过程、凝胶化过程、高分子的相形态结构等等方面 “Fractal”原是一个几何概念, 意为多维、超维或分维, 它打破了原来3 维空间的概念, 不仅可以超过3 维, 而且还可以有小数维(小数点以后 1 位、2 位或更多位数)空间。“Fractal”引用在纤维纱和织物(称为纤维集合体)中, 就是立体多层次、有不同尺度的纤维粗细、长短配合,以及存在着凹凸状点接触的纱、线织物结构。美国和日本都开始注意纤维的分形（Fractal）结构的研究,它们触及了纤维表面凹凸构造的自相似性与大自然的色、光的对应关系。分形理论和混沌论都是20世纪物理学的第三次革命,它研究自然界非线性过程内在随机性所具有的特殊规律性, 从字面上看是指一类极其零碎而复杂但有其自相似性的体系, 是在自然界中普遍存在的。它是用自相似、无标度方法全面描述宏观、中观、微观大自然的科学概念, 混沌是物理概念, 其几何形态则是分形的概念。 天然纤维内在的分形维自然扭曲是其特有的一种分形结构, 它与合成纤维有本质的不同, 合成纤维的机械或化学卷曲, 包括三维卷曲都与天然纤维的从微纤的扭曲开始、自相似放大、最后导致的纤维扭曲截然不同。合成纤维中的超细旦、竹节丝、异截面丝、异收缩丝等都是1 维、2维甚至3维的整数维变化, 而天然纤维则是符合分形理论的分形维变化。上行开采、概念： 上行开采法是
