In West Africa, consumers pay a major attention on the coat colour of the sheep due to religious and cultural reasons. White coated individuals reach selling prices up to three-fold higher than black coated sheep. The aim of this study was to ascertain the genotypic and allelic frequencies of MC1R and ASIP genes in order to assess possible implementation of breeding programmes focusing on the i...

In this study, the influence of dyeing on the antibacterial efficiency of polyamide and polyester fabrics loaded with colloidal Ag nanoparticles and the influence of the presence of Ag nanoparticles on the color change of dyed fabrics were investigated. Dyes C.I. acid green 25 and C.I. disperse blue 3 were used for dyeing of polyamide fabrics, while dye C.I. disperse violet 8 was used for dyein...

Ultrasonic technology is widely used to assist many industrial and domestic applications. However, the effect of ultrasonic washing on the thermophysiological properties of natural based fabrics has not been studied yet. This study aims to examine the relationship between unwashed, ultrasonically washed, and conventionally washed fabrics in terms of their abrasion behavior, flexural rigidity, a...

In light of the eco-friendliness and antimicrobial property mangosteen pericarp (MP), this research investigates antibacterial activity biodegradable poly(lactic acid) (PLA)/poly(butylene succinate) (PBS) nonwoven fabric coated with MP extract. experiment, extract concentrations were varied between 0 (uncoated), 0.3, 0.5, 1, 3, 5 wt%, experimental bacteria strains Escherichia coli Staphylococcu...

Carbon-based fibres hold promise for preparing multifunctional fabrics with electrical conductivity, thermal conductivity, permeability, flexibility and lightweight. However, these fabrics are of limited performance mainly because of the weak interaction between fibres. Here we report non-woven graphene fibre fabrics composed of randomly oriented and interfused graphene fibres with strong inter...

A weaving drawdown is a rectangular grid of black and white squares with at least one black and one white square in each row and column. A pattern results from vertical and horizontal translations of the defining grid. Any such grid defines a tiling pattern. However, from a weaving point of view, some of these grids define actual fabrics while others correspond to collections of threads that fa...

The detection of latent traces is an important aspect of crime scene investigation. Blood stains on black backgrounds can be visualized using chemiluminescence, which is invasive and requires a darkened room, or near-infrared photography, for which investigators need to change filters manually to optimize contrast. We demonstrated the performance of visible reflectance hyperspectral imaging (40...

A concept of a nature-inspired pedestrian bridge which tries to merge architectural, structural and manufacturing aspects in an optimized way is presented. The 18.0-m-span bridge is designed as an overhead spatial frame of a complex double-curved shape, which is composed of twelve modules consisting of lightweight carbon fiberreinforced polymer (CFRP) sandwich construction. The modules are fabr...

Ultra-high molecular weight polyethylene (UHMWPE) woven fabrics have been shown to possess a high strength-to-weight ratio, low density, high-energy absorption, and abrasion-resistant properties. When subjected dynamic impact, the primary failure mode of UHMWPE fabric is yarn pullout, which results from poor inter-yarn friction between weft warp yarns. This work investigates potential use zinc ...

Indonesia is among the largest countries in global rice production. Annual generation of straw about 20 million tons were reported. It therefore, utilization as natural dye considered to minimize pollutant problem. Rice composed 48.7% carbon that generate black color. In this research, dyes ash applied cotton and rayon fabrics, followed by mordanting using lime, alum, ferrous sulphate. The colo...
