Preparación, caracterización y evaluación in virto de textiles de
algodón recubiertos con gel antibacteriano con liberación
prolongada de curcumina
Publicada el 19/03/2015
The aim of this study was to develop a textile-based sol–gel release
system with antibacterial properties intended for medical applications.
Curcumin (a herbal compound extracted from Curcuma longa L.) was
embedded in an acid-catalyzed silica xerogel coating on cotton textiles.
The release of curcumin was found to be diffusion-controlled, as
expressed by the Higuchi and the first-order models. Matrix dissolution
release was ruled out by the absence of dissolved silica in the release
medium. Results from nitrogen sorption analysis confirmed the presence of
mesopores in the xerogel coating, and an increase in both the BET surface
area from 1.95 to 2.23 m2 g–1 and in the mesopore volume from 0.003 to
0.004 cm3 g–1 after the sol–gel treatment. Thicker xerogel coatings
therefore provided greater porosity for curcumin entrapment, leading to
retardation of the diffusion processes and consequently extended release
profiles. The treated samples showed better antibacterial properties
against Staphylococcus aureus (99% reduction) compared with
Escherichia coli (37% reduction). Overall, the developed sol–gel coated
textiles demonstrate promising potential for use as wound dressing
materials.

Christophe Leys. Antimicrobial non-woven polyethylene terephthalate
(PET) fabric containing nano-silver of different concentrations has been
prepared in a novel three step process. Nano-silver has been incorporated
in between two layers of organosilicon thin film deposited by an
atmospheric pressure plasma system. The top layer of 10nm thickness
was used as a barrier to prevent release of nanoparticles from the surface.
The antimicrobial activity of the nano-silver fabrics was tested using
Staphylococcus aureus and Escherichia coli by dilution method. The effect
of silver concentration on the lag phase, the specific cell growth rate, and
the cell concentration has been studied and discussed based on bacterial
growth curves.

Comportamiento de filtros geotextiles en laderas blindadas

Volume 43, Issue 1. Author(s): Ennio M. Palmeira , Janaina Tatto.
Geotextile filters can be used in several geotechnical and
geoenvironmental applications. Regarding the protection of banks or
slopes against erosion caused by the action of waves, these materials can
be employed under revetments and armour layers. This paper presents
results of large scale tests on armoured slopes where geotextile and
granular filters were employed. A wave flume was used in the tests and
three types of nonwoven geotextiles and a conventional granular layer
were employed as filters between the armour layer and the base soil slope.
The armoured slope was subjected to the impacts of waves produced by a
wave generator opposite to the channel slope. Pore pressures in the soil
slope were measured during the tests and soil particles that piped though
the filters and that were entrapped in the geotextile were collected for total
mass and particle diameter measurements. The results obtained showed
that the geotextile and the granular filters presented similar performance.
In addition, retention criteria available for this type of geotextile filter
application provided very conservative results. The findings highlight the
importance of the development of more accurate testing techniques and
filter criteria for designing armoured slopes with geotextile filters.

Fibras de nanotitanio y mora como un nuevo textil con
propiedades anti-amarillamiento y antimicrobianas intrínsecas

Hyun-Chel Kim , Jong-Hui Kim , Sang-Ho Baik , Myung-Seob Khil. The
present work for the first time introduces a new class of textile consisting of
mulberry fibers uniformly laden with titania nanorods. This unique naturalsynthetic composite textile is self-cleaning and environmental friendly. The
utilized composite was characterized by scanning electron microscopy
(SEM), energy dispersive X-ray analysis (EDX), X-ray diffraction pattern
(XRD), electron probe microanalysis (EPMA), transmission electron
microscopy (TEM), thermogravimetric analysis (TGA) and UV-Vis diffused
reflectance spectrum (UV-DRS). The SEM images clearly show
homogeneous distribution of titania nanorods on the surface of mulberry
fibers (MF). XRD and FTIR results confirm the presence of titania in the
composite materials. Antimicrobial potential and UV protection due to
presence of titania nanorods on MFs was investigated in this study.
Results of this investigation indicated that MFs-TiO2 composite exhibit
admirable antibacterial activity. From the antimicrobial kinetic test on E.
coli, it was established that the composite textile possess improved
bactericidal activity than pure mulberry textile. Moreover, titania present on
the mulberry fibers impart anti-yellowing, self-cleaning properties, which
were endorsed due to the scattering effect of UV radiation by titania
nanorods. Thus our study provides the clue/grounds to select mulberry
fibers/titania composite as a material of choice for fabrication of promising
antimicrobial future textile.

Método innovador de funcionalización de textiles para la

Author(s): Marianne Vandenbossche , Dominique Derozier , Mathilde
Casetta , Maude Jimenez , Séverine Bellayer , Michel Traisnel. A new,
efficient and fast process was developed to coat poly(ethylene
terephthalate) (PET) fabrics with acrylic acid (AA) and this novel ecofriendly material was designed to be used as a filtration medium for
complexing heavy metals from aqueous media. PET is impregnated with
acrylic acid, and directly polymerized using a KrF excimer laser. The
conditions of irradiation were optimized using the experimental design
technique: a 40×3.5 mm2 surface was irradiated per pulse, and 24mJ/cm2
and 700 pulses were necessary to obtain a good coating without degrading
the textile structure. For industrial purpose, these conditions were
extended to treat larger surfaces (40×11.5 mm2 pulse) using a fluence of
24mJ/cm2 and 700 pulses. Scanning Electron Microscopy (SEM) and Xray Photoelectron Spectroscopy (XPS) were carried out to characterize the
functionalized surfaces. A thick coating, resistant to low-temperaturewashing was obtained. Finally, the efficiency of this coated textile was
evaluated with copper sulfate solutions: 0.131mg copper was trapped per
cm2 of PET, which is a promising result.

Publicada el 12/01/2015
Composite materials are starting to be used extensively in many industrial applications. This is the case for
example of the transport (automotive, rail and aeronautic), marine, wind energy and construction industries.
New developments such as textile preforming combined with liquid moulding technologies together with recent
automation developments will support this tendency. Although it seems that composite manufacturing
technologies are already mature, actually they are not.

Alfombra muro a muro con calefacción radiante para la
eficiencia energética en el calentamiento de espacios en
edificios no residenciales
Publicada el 22/12/2014
Energy efficiency is using less energy while maintaining an equivalent service. EU set a target for 2020 of
saving 20% of primary energy consumption. Nearly 40% of the energy is consumed by buildings. Large efforts
are being invested in future low energy buildings, but the reality is that existing buildings represent 99% of the
stock. The EPBD recast sets minimum requirements for existing buildings: Member States must set targets for
the transformation of existing buildings into near zero energy buildings by 2014 (consuming 40-60 kWh/m2).
Thus the current average energy consumption (150 -300 kWh/m2) will need to be reduced by <75%. Few
innovative technical systems in the market are directed and optimised for the efficient use of energy in existing
buildings. Therefore RADCARPET will be a radiant heating wall-to-wall carpet covering the floor surface of
non-residential buildings (offices, hotels and educational buildings) that will work as a space heating system.
