Fiber traces are one of (micro)traces that can be found at a crime scene. They are easily transferable and, like other forms of evidence, can provide a link between a suspect and a victim. The main purpose of this review is to present methods developed to examine textile dyes extracted for forensic purposes using different capillary electromigration methods (CEMs). Scientific papers, mainly from the 20th century, provide reliable methods for the separation of water-soluble dyes. However, dyes insoluble in aqueous solutions have been and still are a challenge. Another problem is the sensitivity of the developed methods, which is, in most cases, insufficient for forensic examination of dyes extracted from a single fiber preserved at the crime scene. Although the methodologies already developed and presented in this review have the potential to be applied in a comparative analysis of textile dye traces, there seems to be a lot of work to be conducted. Some ideas on how to resolve these problems are presented and discussed in the article.
纤维痕迹是犯罪现场中可以发现的（微）痕迹之一。它们很容易转移，并且像其他形式的证据一样，可以在嫌疑人和受害者之间建立联系。本次综述的主要目的是介绍为了法医目的而开发的用于检查从不同毛吸管电泳方法（CEM）提取的纺织染料的方法。主要来自 20 世纪的科学论文为分离水溶性染料提供了可靠的方法。但是，不溶于水溶液的染料一直是并且仍然是一个挑战。另一个问题是开发方法的灵敏度，在大多数情况下，对于从保存在犯罪现场的单个纤维中提取的染料进行法医检查是不够的。尽管已经开发并在本综述中提出的方法有可能应用于纺织品染料痕迹的比较分析，但似乎还有很多工作要做。本文提出并讨论了一些解决这些问题的想法。
