Influence of different finishing treatments over mechanical and thermal properties of bed linen
This work aims to assess the relationship between the
mechanical and the thermal properties of summer bed
linen using different softener formulations in home
textiles finishing. Objectively, we intend to study the
effect of different softeners and their concentrations,
based on non-ionic polyethylene dispersions and a
cationic silicone softener micro-emulsion on textile
properties.
The research shown that thermal related properties are
influenced by polyethylene softeners, while the silicone
softener influences the mechanical behavior of the tested
samples. Finally, selected softened samples of bed linen
were evaluated by a dry thermal manikin to validate some
conclusions.(undefined
Cost and efficiency analysis of commercial softeners in the sewability behavior of cotton fabrics
This paper reports a comparative case study on the use of different softening products for bed linen fabrics, specifically regarding the sewability of the fabrics. The market offers a wide variety of commercial formulations of softeners for this purpose, but the composition and price varies considerably. This work was aimed to assess the relationship between the cost and effectiveness of different softener formulations in home textiles finishing. Objectively, the effect of different softeners and their concentrations on sewability of the fabrics was studied. Non-ionic polyethylene dispersions and a cationic silicone softener micro-emulsion in different concentrations and combinations were considered in this investigation.
It was found that a combination of silicone and polyethylene based softeners presents the most interesting cost/performance behavior.This work has been funded by FEDER through Programa Operacional Factores de Competitividade - COMPETE and by national funds by FCT - Fundacao para a Ciencia e a Tecnologia in the context of project PEst-C/CTM/UI0264/2011
Optimization and thermal stability of TiAlN-Mo multilayers
In this work we focus on the optimization and thermal stability of nanocomposite TiAlN/Mo multilayers that were produced by reactive
magnetron sputtering on high-speed steel substrates, with modulation periods below 5 nm. These multilayers were annealed between 600–
900 ºC for 1 h in a vacuum furnace. Preliminary X-ray diffraction results reveal that these coatings are very stable up to 900 ºC, since the multilayer
chemical modulation is not severely affected. At intermediate annealing temperatures the modulation period decreases due to interdiffusion at
the interface, resulting in a thicker interface between metal/nitride and hence decreasing the thickness of those layers.Portuguese FCT/MCES scientific program
