Sažetak
For the purpose of comparing the parameters of the arithmetic mean of the profile (Ra) and the mean value of the square deviation of the profile (Rq), the roughness of eight samples. The original profile was filtered on a suitable cutoff which was calculated according to the weft density. A filtered profile was obtained, ie a part of the profile that includes only wavelengths less than the cutoff, ie 1.02 mm, which includes irregularities in the fabric caused by thread interlacements and yarn morphology. The results show that in this choice of cutoff, the fabrics in plain and satin weave have the greatest roughness in relation to twill weave. In the case of fabrics in plain, with increase of weft density the roughness increases, which is in line with the theory. More interlacements per length will also result in greater roughness. In satin weave fabric, a sample with a lower weft density has higher roughness values, even more than fabric in plain weave. Since the roughness method was mechanical, the presence of a small sense of force on the fabric led to local compressive deformation at the points of contact where the weft system threads were registered regardless of floating warps. The denser structure of satin fabric had a lower roughness due to its greater compactness so the sensor of the test device encountered greater resistance from tensed, compacted weft threads. On the other hand, fabrics in twill weave (K2/2 and K3/1) had the least roughness.
