Elastic bands antimicrobial functionalization
Ferreira, Ana Francisca; Fernandes, Rui Daniel Vilaça; Vieira, Bárbara Marques; Peixoto, Joaquim Jorge Gomes; Felgueiras, Helena Prado; Zille, AndreaSustainability of textile products encompasses the extension of their useful life period during which they adequately serve their intended purpose. Antimicrobial finishings can prevent microbial damage and extend textile lifespan. Even though the functionalization and characterization processes have been thoroughly described for woven, knitted and non-woven textiles, there is a lack of information regarding ela...
Chromatic and medicinal properties of six natural textile dyes: a review of euc...
Santiago, Diana; Cunha, Joana; Cabral, IsabelThe environmental and health-related impacts of synthetic dyes have led to growing interest in natural dyes as sustainable and eco-friendly alternatives. However, natural dyes have been used to dye textiles with limited color shade and poor fastness properties, and little research has been conducted in this field. Additionally, natural dyes also have the potential to provide added functionalities to textiles, s...
Color in sustainable fashion: a reflection on the importance of design education
Lara, Lívia Rosa; Cabral, Isabel; Cunha, JoanaThe fashion industry has a long chain of activities and processes, with complex issues related to environmental, social, economic, and cultural impacts. Faced with the importance of color in products in contrast to the environmental impact of coloration processes, this study addresses the importance of the relationships between the field of design education and textile processes. Design education represents a w...
ARTILES – augmented reality in textile patterns inspired by Portuguese tiles
Oliveira, Manoella; Cunha, Joana; Cabral, IsabelThis paper aims to present the conceptual development of a project in the field of fashion design that brings Augmented Reality (AR) as a means to integrate technology and cultural sustainability over the interface of a fashion product. From the printed pattern, this technology is proposed to improve the interaction between the artifact and people. The Portuguese tiles were chosen as an inspiration for the patt...
Auxetic textile reinforced composites: classification, mechanical properties an...
Hoa, Nguyen N. X.; Peixoto, Joaquim; Cabral, Isabel; Fangueiro, Raúl; Ferreira, Fernando; QUYEN, NGUYEN-TRONGAuxetic textile reinforced composites are increasingly used in various industries such as aerospace, construc tion, automotive, medicine, sport, etc. due to their distinctive advantages. This paper reports a review of the mechanical properties and applications of auxetic composites. This review puts an emphasis on auxetic fibres, yarns, and fabrics that can be used to fabricate auxetic composites.
A review on auxetic knitted fabrics: geometrical structures, auxetic performanc...
Hoa, Nguyen N. X.; Peixoto, Joaquim; Cabral, Isabel; Fangueiro, Raúl; Ferreira, Fernando; QUYEN, NGUYEN-TRONGKnitting technology is one of the most important textile processes. It has advantages of high structural va riability, high materials adaptability, high productivity and huge potential for applications in both apparel and industries. The studies have shown that both weft- and warp knitting have been adopted for producing auxetic knitted fabrics based on different auxetic geometrical structures. This paper summa...
Screen printing of cotton fabric with hydrochromic paste: evaluation of color u...
Gauche, Heloísa; Oliveira, Fernando Ribeiro; Merlini, Claudia; Hiller, Ana Paula; Souto, A. Pedro; Cabral, Isabel; Steffens, FernandaSmart textiles are promising for the future of the textile industry, providing natural fibers with attractive and interactive features. Within this context, it is possible to emphasize the chromic materials, as, for example, the hydrochromic, which alter their visual properties (color) through an external stimulus (water). The purpose of this work is to functionalize and characterize cotton knitted fabric with ...
Auxetic materials and structures for potential defense applications
Hoa, Nguyen N. X.; Peixoto, Joaquim; Cabral, Isabel; Fangueiro, Raúl; Ferreira, Fernando; QUYEN, NGUYEN-TRONGAn auxetic material exhibits exceptional features compared to conventional material. It gets broadened when it is stretched or becomes smaller when it is compressed because it has a negative Poisson’s ratio. Moreover, auxetic materials possess some enhanced properties, such as shear resistance, indentation resistance, fracture toughness, energy absorption, etc. These enhanced properties make the auxetic materia...
Flexible textile printed piezoresistive pressure sensors
Oßwald, E.; Carvalho, Helder; Cabral, Isabel; Souto, A. Pedro; Cunha, A.The combination of sensor technology and textiles substantially extends the range of textile applications. Smart textiles, especially clothing, might increasingly be equipped with pressure sensors. They could be used in the sports or health sector to measure body activities or other activities which are close to the body. Therefore, it is essential to develop flexible sensors which allow to adapt to the propert...
Dynamic qualities of smart textiles: study of stimuli magnitude with chromic pi...
Cabral, Isabel; Souto, A. PedroSmart textile behaviour encompasses changes over time, which are triggered upon a sensed stimulus. With a focus on dynamic qualities, this research sought to study how gradual and reversible transitions of smart textiles can be influenced by the activation variable – stimuli magnitude. Taking into account an analysis of different external stimuli for the same property change, the experimental work was conducted...
