ABSTRACT

The paper introduces the technique of thread-by-thread tear mending in the conservation of canvas paintings and is dedicated to the investigation of difficulties in the reproducibility of bonding qualities. An insight is given into the basics of the bonding technique as well as the requirements on the adhesives. Based on initial test series, the cause of scattering is investigated and examined on the basis of scale effects, thread geometry and general bond qualities. Selected results from uniaxial tensile tests on single thread and canvas strip specimens are presented and discussed. As a result, it can be stated that the scattering is inherent in the material and technology. Therefore, the aim must be to show the range of possible results within further tests to provide reliable data for practical conservation and restoration treatments.

摘要

介绍了画布画保护中的逐丝撕裂修补技术，并致力于研究粘合质量再现性的难点。深入了解粘合技术的基础知识以及对粘合剂的要求。在初始测试系列的基础上，根据比例效应、螺纹几何形状和一般粘合质量调查和检查散射的原因。介绍和讨论了单线和帆布条试样单轴拉伸试验的选定结果。因此，可以说散射是材料和技术所固有的。因此，目标必须是在进一步测试中显示可能结果的范围，以便为实际保护和恢复处理提供可靠的数据。
