The article presents the results of the model textile layered systems, with different applied adhesive medium, in terms of hygienic properties and meeting the requirements of „HEALTHY FOOT – Footwear protecting the proper development and functioning of the child’s feet” mark. The systems were built of cotton fibers textile materials, connected by six kinds of adhesives used in light industry. Comparative studies of hygienic properties were carried out according to standardized test methods, taking into account the change in mass of the surface. The optimal parameters from the footwear hygiene point of view involving textile layer systems, was found in samples with pure forms of the adhesive media – powders, films, and nonwovens, while the worst results were obtained in samples with a pressure-sensitive adhesive. The differences in the results of the study indicate a relationshipbetween the adhesive medium connecting textile materials in layered systems and their hygienic parameters, i.e. water vapor permeability (WVP), water vapor absorption (WVA) and water vapor coefficient. This fact constitutes a premise for further research and detailed analysis in order to confirm the statistical strength of the correlation.

The existing trend in modernization of natural leathers tanning procedures requires elimination of chrome tanning agents. Previous studies have shown that the use of chromium-free technology allows to obtain the high-quality leathers, which can be used in the shoe and upholstery sectors. This article presents the test results of new assortments of natural calf and bovine leathers tanned with modified chrome-vegetable tanning technologies for the purpose to evaluate their applicability in manufacturing of footwear. Organoleptic assessment as well results of laboratory tests, such as physical and chemical parameters, hygiene properties and hazardous substances (chromium VI, formaldehyde, aromatic amines and heavy metals) new ranges of leather, have shown the full compliance with the requirements for the shoe upper leather, ensuring high comfort and durability of shoes manufactured of these leathers. The best results were achieved by vegatable-synthane retanned leathers that exhibited hygienic properties which were exceptionally beneficial to the health. The tested leathers boast proper processing parameters as well as properties ensuring comfortable footwear. Leathers can successfully be applied to other products of light industry.

In recent years, there is an increase in the market share for synthetic leather upholstered furniture, which is competing with furniture upholstered with natural leather. The cost of production of such materials allows the manufacturer to demonstrate flexibility in relation to the rapidly changing trends, but it must meet a series of quality requirements. There are available general requirements for plastics-coated fabrics, it was necessary to update and supplement them with the quality requirements for synthetic leather upholstered furniture. In the article there are presented functional properties of leatherlike materials, and test results for the commercially available materials of that sort, categorized in terms of backing and finish coat. These results as well as analysis of standardized documents, allowed establishing a set of new requirements for coated fabrics upholstered furniture.

The Institute of Leather Industry in Krakow has been testing and evaluating materials designed for special footwear. Such shoes are mainly the interest of the elder who often face the limitation of mobility due to sensible feet, people with temporary limitations of the lower limbs (after various treatments and surgical operations), as well as people with diabetic foot syndrome or rheumatoid arthritis. The analysis of the research allowed selecting as well as to work out new material configurations, that meets the high requirements of such footwear, taking into account the optimal utility and hygienic properties as well as it settles the requirements for physic-mechanical parameters, hygienic parameters and the limits of selected chemical substances for special footwear materials intended for people suffering from limited feet efficiency.

Przeprowadzono badania zawartości 16 WWA w próbkach gleby pobranej pod koniec upalnego lata w odległości: 2,5; 50 i 100 m od jezdni drogi powiatowej Siedlce-Korczew, charakteryzującej się niskim natężeniem ruchu. Próby pobrano w 7 punktach po obydwu stronach drogi. Po analizie jakościowej i ilościowej metodą chromatografii cieczowej i analizie statystycznej wyników stwierdzono, że sumaryczna zawartość WWA nie przekraczała 200 pg/kg s. m. gleby i istotnie zależała od odległości od jezdni. Stwierdzono wiele korelacji występujących pomiędzy zawartością oznaczanych WWA.

The studies of the content of sixteen PAH in the soils sampled at the end of hot summer at the distance 2.5, 50 and 100 m from the Siedlce - Korczew road that is characterized by small traffic, were carried out. The samples were taken from 7 points at both roadsides. After quantitative and qualitative analysis by means of the liquid chromatography method as well statistic analysis it was found that the total PAH content did not exceed 200 pg/kg d. m, of soil and significantly depended on the distance from the road. Many significant correlations between the content of the determined PAH were found.
