色差仪在织物视觉遮蔽性测试上的应用

Application of Colorimeter in the Measurement of Fabric Visual Shielding Property

目前,分光光度计是国内最为通用也相对权威的一种织物视觉遮蔽性测试仪器,但购置成本较高。基于比较背衬黑白板后织物的色差变化的理论可行性,提出并验证了用色差仪测试方法表征织物视觉遮蔽性的新思路。结果表明:对白色织物而言,色差仪、分光光度计和人眼视觉观察结果几乎一致;而对有色织物而言,色差仪的测量结果更加接近于人眼视觉观察结果。因此,色差仪存在着取代分光光度计进行织物视觉遮蔽性评价的可能性。

At present, spectrophotometer is one of the most commonly used and relatively authoritative textile testing equipment for visual shielding property, but the cost is high. Then, since the comparison of color against backing black and white board is feasible in theory, new ideas of testing the visual shielding property of fabrics with colorimeter method are put forward and verified. The results show that the characterization results are almost the same among the spectrophotometer, colormeter and human visual evaluation method for the white fabrics. As for the colored fabrics, the measurement results of colorimeter are much closer to the human visual observation results than that of spectrophotometer. In conclusion, it is possible that the colorimeter can replace the spectrophotometer for the evaluation of the visual shielding property of the fabrics.
