Consumers use their sense of touch instinctively to evaluate a garment's quality and faculty for specific use. The roughness of textiles is an important parameter for customers' choice of garments. This work focused on surface roughness of woven fabrics. A Textile Surface Tester (TST) was used in this study. For surface height variation (SHV) characterization, the standard roughness parameters described in the ISO 4287 was frequently used. During this analysis, we examined the effect of different parameters of manufacturing and finishing samples on the variation in surface roughness. It was found that the fabric type had an important effect on surface roughness as well as the weft count of woven samples, while chemicals treatments, as coating with different commercial products via ink-jet printing and drying processes, did not affect this parameter.
This paper presents an experimental study of impact of water drop on a surface in a spreading regime with no splashing. Three surfaces were studied: virgin glass, coating film and woven cotton fabric at different construction parameters. All experiments were carried out using water drop with the same free fall high. Digidrop with high-resolution camera is used to measure the different parameters characterising this phenomenon. Results show an important effect of the height of the free fall on the drop profile and the spreading behaviour. An important drop deformation at the surface impact was observed. Then, fabric construction as the weft count deeply affects the drop impact. For plain weave, an increase of weft count causes a decrease in penetration and increase in the spreading rate. The same result was obtained for coated fabric. Therefore, the impact energy was modified and the drop shape was affected, which directly influenced the spreading rate.
Inkjet printing is a type of non-impact printing with the ability to produce high quality color images. The application of this
procedure is very delicate in term of the paste composition and the operative conditions. In this field, firstly the present
paper investigates the drying morphologies for the coating film. Then, the effect of film compounds which are widely as
functional coatings in textile was studied. Results show that the drying condition and the system thickener – urea
compounds affect deeply the film coating morphology. Furthermore, the wetting and the impregnation behaviors are
directly related to the studied system compounds and the experiment applications. Finally, these obtained results are
confirmed by the wetting behavior on the knitted polyamide fabrics
