A study was carried out to compare several colorimetric, physical and comfort properties of polyester fabric dyed with indigo type vat dye and traditionally used disperse dye. It was observed that in terms of colorfastness properties the results were found similar for both the dyes, however in some cases indigo showed slightly better performances. While comparing physical properties, though pilling resistance was found similar, abrasion resistance and bursting strength were found better for disperse dyed fabric. The lower drape co-efficient, bending length and flexural rigidity exhibited the improvement of limpness of the indigo dyed sample. The comfort property was also found improved attributed by the enhanced air permeability of the indigo dyed polyester fabric.

This study, mainly focused on the effect of core-sheath ratio, twist and stitch length on the thermal comfort properties of single jersey knitted fabrics produced from various ratios (100:0, 80:20 and 60:40) of cotton/ polyester core spun yarns. The Box-Behnken design tool was used to study coresheath ratio, twist and stitch length on the thermal comfort properties of single jersey knitted fabrics and response surface equations were derived and design variables were optimized. From this study, the findings reveal that the decrease in cotton ratio among the fabrics made from core spun yarns decreases the fabric thickness and hence a more porous structure that results in higher thermal conductivity, air permeability, water-vapour transmission and less thermal resistance. It is also evidenced that, increase in the yarn twist (high) and the stitch length (tight) in the fabric structure makes thicker and less porous fabric which results in higher thermal resistance and lesser thermal conductivity, air permeability and water-vapour transmission.

Measuring local levels of marine pollution by microplastics (MP) and identifying potential sources in coastal areas is essential to evaluate the associated impacts to environment and biota. The accumulation of floating MP at the sea surface is of great concern as the neustonic habitat consists of a feeding ground for primary consumers (including filter-feeders) and active predators, which makes these organisms a relevant via of MP input into the marine trophic chain. Here, a baseline evaluation of MP accumulation at the sea surface was conducted with a neuston net (335 μm mesh) at the Arrábida coastal area, in Portugal. The study site encompasses a marine protected area and an estuary, both under strong anthropogenic pressures due to multiple activities taking place. A short-term investigation on local spatiotemporal distribution, concentration and composition of MP was performed for the first time, through the monthly collection (summer 2018 to winter 2019) of samples at 6 stations. All the neuston samples contained MP and their mean concentration was 0.45 ± 0.52 items m−3 (mean ± SD). Both the averaged MP:neuston and MP:ichthyoplankton ratios were higher in December, when concentrations of organisms decreased. Temporal distribution patterns followed expected trends, as MP concentration was clearly higher in winter months due to precipitation and runoff. Although mean MP concentrations did not vary significantly between sampling stations, there was a spatial distribution of MP in relation to particle shape and size. Fragments were the most abundant shape and MP belonging to 1–2 mm size class were dominant. Amongst a diversity of 10 polymers identified by FTIR analysis, polyethylene (PE), polypropylene (PP) and copolymer PP/PE were the most abundant. Potential links between local sources/activities and the different polymers were suggested. Altogether, the information provided in this study aims to raise awareness among the identified sectors and consequently to act toward the prevention of MP inputs in the region.
