Fabric properties

Silver nanoparticles (Ag NPs) with a size of around 9 nm were fabricated and quantified through fluorescence quenching of rhodamine B (RhB). A series of solutions composed of RhB with various concentrations of Ag NPs ranging from 0.09 pM to 0.98 pM were prepared, and optical properties were investigated by absorption and fluorescence spectroscopies.

The plasmon characterization of AgNS on paper was systematically investigated by the diffuse reflectance spectroscopy. The fabricated paper-based SERS substrates were used to detect melamine in an aqueous solution and to determine the influence of type RAs on the enhancement factor (EF) and signal uniformity of SERS substrates. Among the four types of RAs, the SERS substrates used NaBH4 have the highest SERS signal with the limit of detection of 10-8 M for melamine and the EF = 2.3 × 109 .

The 3D printing PMMA/ZrO2 filaments with a diameter of 1.75±0.05 mm were fabricated by using a single-screw extruder at temperatures of four heating zones of 190, 200, 210, and 210°C. Testing samples were prepared from the extruded filaments by using a fusion deposition modeling 3D printer and a Haake MiniJet piston injection molding machine. Fourier transform infrared spectroscopy, mechanical properties, field emission scanning electron microscopy (FESEM), differential scanning calorimetry, and thermogravimetric analysis of the filaments were investigated.

The objective of the present study is to produce base layer winter active sportswear fabrics using natural and synthetic fibres and their blends which will deliver good comfort properties. Polyester, wool and bamboo fibres were selected for this study. Polyester is the most common fibre used in sportswear, wool is increasingly being used in sportswear and bamboo is a relatively new fibre that offers properties suitable for base layer sportswear. Bamboo is also regarded as a 'green' and eco-sustainable fibre.

While it is recognised that knitted fabrics may have their place in firefighting PPC, especially for undergarments, from the point of view of fire performance, strength and presentation, woven fabric constructions appear to be more suitable for work wear applications. Hence, this study is concerned with developing and testing a range of functional, woven Station Wear fabrics designed to enhance flame protection, durability and thermo-physiological comfort properties. In trying to improve all three aspects, a compromise in the properties of fabrics developed would be very likely.
