Among the possible ionic crosslinkers Ca2+ is most widely used. However, due to its numerous physiological functions, other cations such as Sr2+ may be more suitable depending on application. Because a systematic comparison currently lacking, this work aims compare solutions of CaCl2 and SrCl2 alginate- cellulose-based materials investigate their effects structural biological properties 3D bioprinted scaffolds. In particular, swelling degradation under cell culture conditions, mechanical...

Lower-limb prosthesis design and manufacturing still rely mostly on the workshop process of trial-and-error using expensive unrecyclable composite materials, resulting in time-consuming, material-wasting, and, ultimately, prostheses. Therefore, we investigated possibility utilizing Fused Deposition Modeling 3D-printing technology with inexpensive bio-based bio-degradable Polylactic Acid (PLA) material for socket development manufacturing. The safety stability proposed 3D-printed PLA were...

This paper reports the effect of woven fabric construction on macroporosity properties. The area a macropore's cross section, equivalent, maximum, and minimum pore diameters, density, open porosity are observed in this research involving parameters—yarn linear tightness, weave type, denting. Predictive models, determined by genetic programming, derived to describe influence construction. results show very good agreement between experimental predicted values. work provides guidelines for...

Polysaccharide hydrogels and metal alloy nanoparticles have already found use in a range of biomedical applications. Nickel-copper (NiCu NPs) are particularly promising due to their tunable properties, such as ferromagnetism, biocompatibility, antimicrobial activity. At the same time, polysaccharide made polymer mixtures alginate methylcellulose with incorporated reported scientific literature. In view this, this work, NiCu NPs combined 3D printed construct geometrically customizable...

Abstract Low moisture absorbency of hydrophobically coated flame-resistant (FR) fabrics do not correlate well with the thermophysiological comfort. In this frame, we were first to study effect screen-printed microfibrillated cellulose (MFC) on fabric’s breathability and build-up transfer as user-friendly wear-related comfortable coating. The amount MFC applied its patterning was varied using different printing parameters, density thickness FR fabric, studied by add-on measurement microscopic...

A new experimental model based on the geometric parameters of a woven structure's yarn linear density and fabric tightness has been developed to predict volume porosity fabrics. The is factor analysis. Experiments involve fabrics made from staple yams, but mathematical can also be applied mono- or multifilament yarns. results correspond very well with calculated values according proposed equation.

Among many other materials for the reinforcement of composites, technical fabrics are increasingly being used same purpose, especially from glass and basalt tows, which have good mechanical properties.. During tensile stress these elongated in direction force, at time they contract crosswise relation to action force. In this paper properties woven made yarns were investigated. Measurements focused on lateral contraction, according Poisson’s ratio can be calculated. For purposes, an...

Abstract This paper reports the influence of weave and method stitching on mechanical properties double woven fabrics. Double fabrics have a more complex construction, which is altered not only by type weave, yarn fineness, thread density in comparison with single fabrics, but also stitching. The main goal our research was to find out if statistically important effect selected such as breaking strength, elongation, tearing wrinkle recovery fabric stiffness, order extend knowledge...

This paper presents an experimental model to predict the porosity of woven fabrics made from staple-fibre yarns, particularly with regard area pore cross-section, equivalent diameter, maximum and minimum diameters, density, open porosity, on basis geometrical parameters structures, i.e. thread linear weave factor, relative fabric density. The validity models is determined by a three-factor analysis.
