Optimization of the fiber/matrix interface and integration of a photochromic molecule in the fiber/matrix system
No full textMolecules and supramolecular that are capable of undergoing structural rearrangements when subjected to an external stimulus have attracted a great deal of attention as they can represent a new way to design smart textiles. Azobenzenes are stable molecules in both the isomeric states, i.e., open and closed forms. By mimicking nature, one of the most significant challenges in the realization of switches is to integrate multiple and independent reactive units in a single molecular system allowing to couple a photochromic activity with a mechanical activity to obtain a photo mechanically activatable system. Among the different inputs, photons have been considered as one of the most promising for application in the textile field. This study aims to explore the possible ways to integrate a diarylethene (DTE) either in the core of the fiber or on its surface to create a photoactive textile structure. The integration of DTE by melt spinning into a poly (methyl methacrylate) matrix has demonstrated the feasibility of the process. Nevertheless, even if a photosensitive effect has been observed, the low quantity of molecules coupled with the thermal constraints do not make this process feasible on a larger scale. To overcome this problem, it was considered to integrate the DTE in a functional coating formulation by dispersing them in a polyurethane matrix with a coating step. This part of the study focuses mainly on the fiber/matrix adhesion mechanisms to determine the best couples in terms of adhesion. The results obtained after the pull-out test showed that the polyamide/polyurethane couple has the highest work of adhesion compared to the polypropylene or polyethylene terephthalate ones

Light and darkness - the ephemeral art of the earth
No full textZanieczyszczenie sztucznym światłem jest coraz bardziej
zauważalnym problemem współczesnego świata. Codziennie zamieniamy noc
w dzień, dzięki rozwiniętej technologii, nie zważając na drogocenny wpływ
naturalnego światła, ciemności i rytmu dobowego na jakość życia niemalże
wszystkich organizmów żywych. Artykuł przedstawia przykłady wpływu tego
zjawiska na środowisko naturalne oraz człowieka, skalę jego oddziaływania
i tempo rozwoju. Porusza także temat głównych źródeł sztucznego
oświetlenia, zagłuszających nocny krajobraz oraz egzemplifikuje próby niwelowania
negatywnych skutków zanieczyszczenia sztucznym światłem, podejmowane
współcześnie. Przedstawiono zagraniczne formy ochrony naturalnego
ciemnego nieba oraz przykłady inicjatyw podejmowane na terenie Polski. Na
podstawie koncepcyjnego projektu konkursowego land artu zlokalizowanego
w Izerskim Parku Ciemnego Nieba, zaprezentowano sposoby poszukiwania
korelacji pomiędzy opisanymi zjawiskami a rozwiązaniami architektoniczno-przestrzennymi.Artificial light pollution is an increasingly noticeable problem in the
modern world. Thanks to advanced technology, we turn night into day every
day, regardless of the precious influence of natural light, darkness and
circadian rhythm on the quality of life of almost all living organisms. The article
presents examples of the impact of this phenomenon on the natural
environment and human, the scale of its impact and the expansion rate. It also
puts forward the subject of the main sources of artificial lighting that drown
out the night landscape and exemplifies contemporary attempts to reduce the
negative effects of pollution with artificial light. It describes foreign forms of
protection of natural dark skies and examples of initiatives undertaken in
Poland. On the basis of the competitional, conceptual project of land art
located in the Izera Dark-Sky Park, methods of searching for correlation
between the described phenomena and architectural and spatial solutions
were presented

carbonization. The morphology the as-obtained copper-doped hydrochar was examined by SEM. The
resistive heating properties of the hydrochar was studied by applied various voltages. In addition,
characteristics parameters were calculated by fitting data from the heating and cooling section. The
relevance between temperature and the corresponding required electrical power was also established.
The results showed that copper-doped hydrochar exhibited excellent resistive heating range and
electrical energy efficiency
Linking co-creation to modularity to respond to consumers expectations and improve production efficiency
No full textThis paper aims to understand what the consumers intend to co-create, secondly if modular co-created
products can respond to consumers’ expectations and thirdly, if the process and production efficiency
could be improved, even for small orders, when based on modular products.
This data will serve as a basis for understanding what methods or processes can be applied and benefit
consumers, brands and the supply chain.
A single closed question was made to the consumers. In addition, one open question was made to the
fashion designers and another to the supply chain experts. These were created based on a literature
review, study question, and propositions.
The findings show that the consumers prefer to co-create full fashion products. Fashion designers and
supply chain experts were unanimous about the improvement of the process and production efficiency
due to modular products, even when producing small orders. Although, when responding to the
consumers’ expectations, some concerns were raised by the fashion designers.
This paper will enable, in the future, the development of a consumer, brand and supply chain cocreation
streamlined framework
Knitted interdigital capacitive strain sensor for wearable applications
No full textWearable electronics is a rapidly growing field that has recently begun to enter the consumer electronics
industry with viable commercial devices. To fulfil the increased demand for wearable devices robust,
compact, reliable, and cost-effective solutions are required. As a result, it is critical to do extensive
research into suitable materials and manufacturing processes. This article describes the creation of a
strain sensing textile-based interdigital capacitive sensor that is highly configurable, consumes minimal
material, produces no waste, and is reproducible and rapid in mass production utilizing computerized
weft knitting technology. In this study, it was shown that the knitted interdigital capacitive sensor
structure could match the high working range necessary for wearable electrical and soft robotic
applications, thanks to its capacity to stretch up to 100%. This work is expected to advance existing
technology in wearable electronics and soft robotics in terms of human body motion sensing
Analysis of thermal aging effect on the tensile strength of textile materials intended for the reinforcement of conveyor belt
No full textWoven fabrics produced from high tenacity (HT) polyester/polyamide 66 yarns are most widely used to
reinforce conveyor belts in the mechanical rubber goods industry. The tensile property of the conveyor
belt is primarily dependent on the property of fabrics used to reinforce the belt. During the production
process of the conveyor belt, the textile-rubber reinforcement undergoes a vulcanization process at high
temperature to provide compulsory physio-mechanical properties of the belt by adhering the woven
fabric with a rubber. Subjecting textile materials to high temperatures for the vulcanization process has
an influence on the mechanical properties of the woven fabric. The main aim of this work was to
investigate the effect of thermal aging on the tensile property of HT polyester yarn and woven fabric
which is intended to reinforce conveyor belt. An extensive experiment on HT polyester yarn and the
woven fabric was conducted by subjecting the textile materials to various aging temperatures.
Additionally, the tensile property of fabrics after the vulcanization process of the conveyor belt was
conducted to fully understand the effect of vulcanization temperature on the properties of woven fabric.
The experimental test results of polyester yarn, woven fabric, and fabrics removed from the conveyor
belt revealed that vulcanizing of the textile reinforced conveyor belt at high temperature(220 °C) can
diminish the tensile strength and increase the elongation at break of the yarn and fabric
The Significance of Inconspicuousness - about Smart Contracts
No full textThis article pertains to smart contracts, i.e. an innovative way of concluding
contracts, which is a potential alternative to classic contracts based on civil
law. In the first part of the text, to illustrate the possible revolutionary role of
smart contracts, two examples of inconspicuous discoveries and changes in
history that have led to fundamental transformations in the world are discussed.
Then, the smart contracts are characterised in relation to other types of
contracts in terms of how the agreements concluded with them are enforced.
Furthermore, this paper discusses the technical properties of these contracts
as well as the advantages and disadvantages resulting therefrom in relation
to classic contracts based on civil law. The summary suggests the possible
future development of smart contracts as a way of concluding contracts that
