This study objectively evaluates the uneven appearance of the two-needle decorative seams of leather seat covers. The investigation is based on both measurement of the stitch slant angle by image analysis and measurement of the penetration force influenced by different cutting points of the needles. To record the unevenness the new parameter, the d...

The creasing of textiles was evaluated by means of the innovative method of measuring the angle of recovery. Our aim is to find statistically significant features contributing to the determination of creasing materials. For this purpose, to identify the inner structures of data, the method of PCA analysis was used a method with latent variables. By...

The authors of the article are presenting an innovated method of measuring the angle of recovery. The method of measuring was designed to grasp more realistically creasing of textiles when they are worn. The next part of the article is dealing with the evaluation of the influence of material of the textile on its creasing. First the initial speed o...

The article introduces a new methodology of measuring which enables to examine properties of materials (bending rigidity and creasing) in different directions, or more precisely the anisotropy of mechanical properties. The principle of the new method consists in measuring circular samples. This recently suggested method is very effective and enable...

Creasing is one of the most important properties of textiles for apparel application. Most fabrics are regularly evaluated by means of etalons, that is, visual standards. Nevertheless, due to the disadvantages of visual evaluation, which is unreliable and time consuming, several objective methods were developed. In this article, a new objective met...
