Pozycja Scale and composition, a strategy of redeveloping the historic area in Shanghai Old Town(Lodz University of Technology Press, 2023) Xuanbing YangThe old town of Shanghai is the cradle of Shanghai city and still at the centre of the grand urban pattern. Being an important historical and cultural area, together with its surrounding district formed the core of the city's economy, public activity and culture. The renewal of the old town will also be a crucial component of the establishment of Shanghai as a distinct global city which combines difficulties from all aspect of the economic sustainability and cultural feature and no longer can be avoided in the following development. Complicated and specific issues could be located in the renovation and design of the old town. And this study mainly hopes to discuss the realization of the cultural feature and the urban fabric in the process of redevelopment, focusing a certain area of the old town. The area selected was the block between Wangyun Road and middle Henan Road, in the centre of the old town, which significantly influenced the continuity of the urban fabric, as the object of the research. Through detailed mapping and field visits, we explored the variegated and spontaneous spatial characteristics of the town’s fabric and the unique local humanistic structure reflected in between. Searching for a way to achieve the integral development and cultural continuity in the context of local urban renewal. Through research, we found that in the old town of Shanghai which has the characteristics of Jiangnan water town landscape and Lilong Shikumen residence, scale and composition are important factors for understanding the spatial and humanistic structure of this area, corresponding to the richness of morphological texture and the anfractuous spatial network. On this basis, attempt to propose a method of typifying different scales and combinations, thus, achieve the goal of guiding the following practice of the local urban redevelopment.Pozycja Estimating biodegradation of cotton fabric by soil burial(Wydawnictwo Politechniki Łódzkiej, 2022) Sánchez-Martínez, Ainhoa; Belda-Anaya, Raquel; Capablanca, Lucía; Payá, Jaime Gisbert; Bonet-Aracil, MarilésToday we can see a greater awareness of sustainability and environmental protection, however, there are many environmental impacts that are not measured and therefore taking measures to minimize them is not easy. In this article we intend to evaluate the biodegradability of a cotton fabric through the generation of one of the greenhouse gases, CO2. For this, the cotton fabric is buried in an artificial ecosystem and accelerated aging is carried out. The results show that the biodegradability of cotton fabric is around 70-80% of the biodegradability of cellulose.Pozycja Analysis of thermal aging effect on the tensile strength of textile materials intended for the reinforcement of conveyor belt(Wydawnictwo Politechniki Łódzkiej, 2022) Lemmi, Tsegaye Sh.; Barburski, MarcinWoven 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.Pozycja Modification of cotton fabric using a three-component Ag/TiO2/g-C3N4 composite to improve protection against UV radiation(Wydawnictwo Politechniki Łódzkiej, 2022) Glažar, Dominika; Štular, Danaja; Urbas, Raša; Tomšič, Brigita; Šobak, Matic; Jerman, Ivan; Chouhan, Raghuraj S.; Simončič, BarbaraIn this study, the chemical modification of cotton fabric to develop UV-protective properties is presented. For this purpose, TiO2 and a three-component Ag/TiO2/g-C3N4 composite were synthesised ex-situ and were applied to cotton fabric using a pad–dry–cure method. The presence of the composite on the cotton fibres was detected using the SEM, EDS and FTIR methods and with a digital microscope. The results show that the application of TiO2 increased the UV protection of the cotton fabric compared with the untreated fabric. The combination of TiO2 with Ag and g-C3N4 in the composite further improved the UV protection of the cotton fabric, as the absorption in the UVA range increased significantly. This resulted in a large increase in the UPF value, placing the cotton fabric in the excellent protection category. This proves the cumulative effect of the components in the composite.Pozycja Research on surface geometry of woven fabrics of different structure(Wydawnictwo Politechniki Łódzkiej, 2022) Kosiuk, Gabriela; Matusiak, MałgorzataThe geometric structure of surface of textile materials is of significant functional, operational and aesthetic importance. Generally, the geometric structure of the surface of materials consists of three main elements: shape, waviness and roughness [1,2]. Parameters characterizing a quality of fabrics surface, i.e. surface topography are strongly related to the fabrics’ structure, raw material composition and a way of finishing. The aim of presented work was to analyse the parameters characterizing the geometric structure of the surface of cotton woven fabrics with different weaves. Totally, 12 fabric variants were the objects of the investigations. They were woven fabrics of 6 weaves and 2 kinds of weft yarn. Surface topography measurements were made by means of the MicroSpy® Profile profilometer by FRT the art of metrology™ [3]. Using the Mark III software cooperating with the profilometer, the basic parameters characterizing the geometric structure of the fabrics’ surface were determined according to standard [4]. Results showed that the fabrics differ between each other in the aspect of the majority of parameters characterizing the surface geometry. Statistical analysis confirmed that weave and linear density of weft yarn significantly influence the surface properties of the investigated fabrics.
