Abstract
The abrasion resistance and susceptibility of textiles to surface damage is an important issue for their utility properties. The currently used test method for abrasion resistance assessment has been based on criteria that define the breakage point of fabrics, visually identified and highly depended on observer perception. Taking under consideration the character of abrasion assessment process the efforts were made to elaborate the new alternative test technique which supports this evaluation. The abrasion resistance tests using instrumental method (based on image analysis tools) parallel with standard method were carried out. There were two steps of analysis. Firstly, the preliminary analysis for selecting the most effective and sensitive algorithm was carried out. Secondly, the final analysis, involving whole range of captured image samples, using chosen algorithm, based on image histogram calculation was done. Summarizing the abrasion resistance tests results obtained using both standard and instrumental methods it was found that the instrumental method gave more complex results during identification of surface changes caused directly by the abrasion process. The instrumental method is more sensitive to surface texture modifications and colour fade and its discrimination threshold is significantly lower than standard methods with qualitative breakage criteria (such as broken threads, loss of pile).
Highlights
The abrasion resistance and susceptibility of textiles to surface damage is an important issue for their utility properties and is widely discussed in the subject literature
The analysis showed the existence of a linear correlation between the abrasion resistance of woven fabrics and the yarns these fabrics were made of
Fabric 1 showed gradual damage of pile and progressive colour fade, which caused the loss of aesthetic properties without reaching the breakage criteria described in the standard, Fabric 2 showed intense damage of singular filaments in threads after just 6000 rubs, which caused the occurrence of a dense pile-like structure on the fabric surface made of damaged filaments
Summary
The abrasion resistance and susceptibility of textiles to surface damage is an important issue for their utility properties and is widely discussed in the subject literature. The abrasion resistance parameters are crucial in durability evaluation, especially when the new kind of treatment of textile product surface is created. The proper abrasion resistance was highly important for textile products when electronics elements have been incorporated (smart textiles), as was investigated in research work [4] These elements could have different functions, for example, transmitting an ECG signal in medical applications or collecting energy for smart textile accessories which use fibres with piezoelectric properties, as was described in research works [5,6,7,8] The fibres-based construction of photovoltaic units, dedicated to electric power harvesting, for smart textile garments purposes, but as a renewable power source, was investigated by Zhang et al [9].
