Visualisation of fingermarks and grab impressions on dark fabrics using silver vacuum metal deposition [PDF]

, 2013
Vacuum metal deposition (VMD) involves the thermal evaporation of metal (silver) in a vacuum, resulting in a uniform layer being deposited on the specimen being treated.

Optimizing the colour and fabric of targets for the control of the tsetse fly Glossina fuscipes fuscipes [PDF]

, 2012
Background: Most cases of human African trypanosomiasis (HAT) start with a bite from one of the subspecies of Glossina fuscipes. Tsetse use a range of olfactory and visual stimuli to locate their hosts and this response can be exploited to lure tsetse ...

Development auxiliaries for dyeing polyester with disperse dyes at low temperatures [PDF]

, 2017
High-molecular weight organic compounds known as carriers are widely used to expedite polyester dyeing at atmospheric pressure at 100 °C. However, carriers are usually poorly biodegradable and can partially plasticize fibres. Also, dyeing at temperatures

Theoretical simulation of the infrared signature of mechanically stressed polymer solids

Beilstein Journal of Organic Chemistry, 2017
Mechanical stress leads to deformation of strands in polymer solids, including elongation of covalent bonds and widening of bond angles, which changes the infrared spectrum.

Effect of fibre treatments on interfacial shear strength of hemp fibre reinforced polylactide and unsaturated polyester composites [PDF]

, 2011
Surface treatment of hemp fibres was investigated as a means of improving interfacial shear strength (IFSS) of hemp fibre reinforced polylactide (PLA) and unsaturated polyester (UPE) composites. Fibres were treated with sodium hydroxide, acetic anhydride,

Anti-Frothing Effect of Poultry Feathers in Bio-Based, Polycondensation-Type Thermoset Composites

Applied Sciences, 2020
The formation of polycondensation-type thermoset resins from natural reactants such as citric and glutaric acid, as well as 1,3-propanediol and glycerol, was studied. Monitoring the mass loss by thermogravimetric analysis (TGA) allowed the rate constants

Development of an individual warp beam tension control system for warp assembling machines in direct warp preparation

Journal of Engineered Fibers and Fabrics
Warp preparation is a process prior to weaving that brings all the ends side by side and then winding them on a warp beam with the same tension and length at a predetermined width, density and length.
