Sažetak
In woven fabrics, the typical topography is expressed by the periodic repetition of waves in the vertical and horizontal directions resulting from its structure. The term roughness refers to height differences in the range of variations on the fabric surface, quantified by deviations in the direction of the normal vector of the actual surface from its ideal shape, and is characterized by the height and width of the wave. The roughness profile is a profile derived from the primary profile neglecting the long-wave components using a profile filter. Each parameter is classified according to the primary profile (P), roughness profile (R) and waviness profile (W) to categorize different aspects of the profile. To process the data from the primary profile, it is necessary to create a roughness profile, which is done by filtering. It is necessary to select the appropriate wavelength of the section (cutoff line), which separates the roughness from the waviness. In the case of fabric at the level of weave, threads, thread morphology. In the experimental part of the work, samples in plain and satin weave were examined, with the same warp and weft densities. By selecting two cutoff values, two profiles were obtained for each sample. The first profile includes only wavelengths less than the cutoff line (1.02 mm) equal to the length between the two weft threads increased by 10%. The cutoff of the second profile is determined by estimating the one wavelength of the approximated path of one thread in the fabric passing along one weave unit of fabric increased by one thread. A comparison of the filtered profiles shows a similarity between the two profiles in both samples, which suggests that the roughness of the fabric is more influenced by the density of the threads than the fabric weave.
