Badania trwałości funkcjonalnie drukowanych dzianin przeznaczonych na podkoszulki

Knitted shirts are an appropriate carrier of easily readable information, and therefore, in recent years, QR Codes have been very often printed on T-shirts. With the purpose of investigating QR Code fastness printed on textiles, in this paper a methodology is proposed for the durability assessment of functionally printed knitted fabrics that includes the implementation of long-term care and wearing simulation - which the T-shirts are exposed to over their lifetime. Dimensional changes after multiple washing and drying cycles were determined for non-printed and functionally printed white knitting, as well as the abrasion resistance and tendency to surface pilling after multiple rubbing cycles. The effect of usage simulation on the functional print’s durability was defined, as well as the color fastness, readability and aesthetic properties. It was found that the structure of knitted fabrics, their dimensional stability, the number of care and wear cycles performed, the printing technique and size of black modules in the QR Code all have an influence on the results obtained.Z włókien naturalnych najczęściej wytwarzane są materiały zaliczane do grupy modnych wyrobów odzieżowych. Takim produkowanym wyrobem są dziane koszulki T-shirts. W trakcie ich produkcji niezbędnym jest wszywanie metek i innych informacji o sposobie konserwacji i użytkowania. Z uwagi na koszty produkcji i skrócenie samego procesu produkcyjnego wielu producentów decyduje się na wykonywanie nadruków na tych wyrobach odzieżowych. Dokonano ocenę trwałości wybarwień kodów QR w wyrobach włókienniczych i opisano metodę oceny trwałości i funkcjonalności wydrukowanych kodów na dzianinach w odniesieniu do ich właściwości użytkowych i funkcjonalności stosowania tego typu nadruków. Przeprowadzono analizę zmian wymiarów ubioru po wielokrotnych cyklach prania i suszenia, dla dzianin niedrukowanych, a także funkcjonalnie drukowanych białych dzianin. Została również przeprowadzona ocena odporności na ścieranie i skłonność do tworzenia się powierzchniowego pillingu po wielokrotnych cyklach ścierania. Oceniano również trwałość wybarwień, poziom rozróżnialności kodów QR i właściwości estetyczne. Stwierdzono, że struktura dzianin, ich stabilność wymiarowa, liczba wykonanych cykli noszenia, technika drukowania, a także rozmiar czarnych modułów w kodzie QR mają wpływ na uzyskane wyniki badań

The tectonic evolution of a critical segment of the Dinarides‐Alps connection: Kinematic and geochronological inferences from the Medvednica Mountains, NE Croatia

The transition zone between the Alps and Dinarides is a key area to investigate kinematic interactions of neighboring orogens with different subduction polarities. A study combining field kinematic and sedimentary data, microstructural observations, thermochronological data (Rb‐Sr and fission track), and regional structures in the area of Medvednica Mountains has revealed a complex polyphase tectonic evolution. We document two novel stages of extensional exhumation. The first stage of extension took place along a Late Cretaceous detachment following the late Early Cretaceous nappe stacking, burial, and greenschist facies metamorphism. Two other shortening events that occurred during the latest Cretaceous‐Oligocene were followed by a second event of extensional exhumation, characterized by asymmetric top‐NE extension during the Miocene. Top‐NW thrusting took place subsequently during the Pliocene inversion of the Pannonian Basin. The Cretaceous nappe burial, Late Cretaceous extension, and the Oligocene(‐Earliest Miocene) contraction are events driven by the Alps evolution. In contrast, the latest Cretaceous‐Eocene deformation reflects phases of Dinaridic contraction. Furthermore, the Miocene extension and subsequent inversion display kinematics similar with observations elsewhere in the Dinarides and Eastern Alps. All these processes demonstrate that the Medvednica Mountains were affected by Alpine phases of deformations to a much higher degree than previously thought. Similarly with what has been observed in other areas of contractional polarity changes, such as the Mediterranean, Black Sea, or New Guinea systems, the respective tectonic events are triggered by rheological weak zones which are critical for localizing the deformation created by both orogens
