After confirmation ZnO NP content distribution within...
This work compares the effect of different types surface treatments natural fibrous materials, particularly flax, on mechanical properties thermoplastic polymer composites for application in automotive sector. The materials can improve compatibility with polymeric materials. Different were applied, namely: cleaning (L); alkali (A); coupling functional groups, such as benzoyl (B), amino (SA), epoxy (SE); corona (C). After treatments, combined polyolefin (TPO), by compression moulding. tests...
Pressure injuries (PIs) are a major public health problem and can be used as quality-of-care indicators. An incipient development in the field of medical devices takes form Smart Health Textiles, which possess innovative properties such thermoregulation, sensing, antibacterial control. This protocol aims to describe process for new type smart clothing individuals with reduced mobility and/or who bedridden order prevent PIs. paper's main purpose is present eight phases project, each...
In recent decades, the interest in responsive fibrous structures has surged, propelling them into diverse applications: from wearable textiles that adapt to their surroundings, filtration membranes dynamically altering selectivity, these showcase remarkable versatility. Various stimuli, including temperature, light, pH, electricity, and chemical compounds, can serve as triggers unleash physical or changes response. Processing methodologies such weaving knitting using yarns, electrospinning,...
Fibrous materials are often used in the manufacturing of fire protection devices such as curtains. Their optimization and improved performance is still a topic interest. The present work aims to develop test new combination fibers arranged various 2D 3D patterns with coatings. For this purpose, basalt were added into glass fiber fabric, wires shape memory material (SMM) inserted fabric create air pockets induced by temperature. In curtains, base structure basket pattern, all combinations...
Biological hazards can be defined as substances that endanger the life of any living organism, most notably humans, and are often referred to biohazards. Along with use personal protective equipment (PPE), early detection contact is essential for correct management resolution a biological threat, well lower mortality rates those exposed. Herein, Prussian blue (PB) was evaluated functional compound applied on polyester knits act an on-site sensor bacteria detection. In order study best...
Chemical protective clothing (CPC) has become mandatory when performing various tasks to ensure user protection and prevent chemicals from contacting the skin causing severe injuries. In addition protection, there is a need develop simple mechanism that can be attached CPC capable of detecting alerting presence harmful chemical agents. this study, double-sensor strategy was investigated, using six different pH indicators stamped on cotton polyester knits detect acidic alkaline substances,...
Abstract The SLS additive manufacturing industry enables the development of products for diverse applications with distinct properties due to its excellent surface finish and ability create varied part geometries, but it consumes high-performance materials high acquisition costs.
