Abstract

Pilling is a defect that affects the appearance of fabrics, being its assessment carried out by the textile sector using a subjective method (reference). This method is simple and works well in most cases. However, uncertainties may arise when complicated cases are under evaluation. The current study addresses the use of an optical 3D-system for the topographic surface reconstruction of fabrics for their objective assessment. With the topographic data of the fabrics, it was calculated the total volume of pilling formed in their surfaces. Their equivalent pilling grades were also achieved through use of a correspondence model. A results comparison was then carried out with both methodologies (3D-system and subjective), which made possible to identify cases of analysis where the grading attributed to the fabrics did not match. These cases were thoroughly analyzed, and it was found that one of the studied fabrics seems to have been over-estimated whereas one other seems to have been under-estimated when initially graded with the subjective methodology.

摘要

起球是影响织物外观的缺陷，是纺织部门使用主观方法（参考）进行的评估。这种方法很简单，并且在大多数情况下效果很好。但是，在评估复杂的案例时可能会出现不确定性。当前的研究解决了使用光学3D系统对织物进行表面形貌重建以进行客观评估的问题。利用织物的地形数据，可以计算出织物表面形成的起球总量。通过使用对应模型也可以达到其等效的起球等级。然后使用两种方法（3D系统和主观方法）进行了结果比较，从而可以识别出归因于织物的等级不匹配的分析案例。
