Máquinas para la producción del espacio: los diagramas como herramientas del planeamiento relacional

No habitamos ciudades sino territorios, la ciudad-territorio que no es árbol, sino rizoma, sistema que produce lo múltiple, extensión superficial ramificada en todas direcciones (redes) que, en sus zonas de intensidad, genera concreciones (nodos, centralidades). ¿Cómo articular esta ciudad que se expande indefinida e improgramablemente? Quizás desde un urbanismo cuyo objetivo no sea la representación de la Idea, sino la producción inmanente de espacio dotado de sentido. Urbanismo al servicio de la expresión de la subjetividad a través de códigos ecológicos proyectados sobre el territorio para garantizar la sostenibilidad de sus potenciales. Se investiga así un planeamiento cuyo papel es la modelización del campo de juego: Establecer trazados diagramáticos entendidos como expresión gráfica y procedimental para dotar de infraestructura relacional a la ciudad contemporánea. Diagramas que son el resultado de un debilitamiento de su clásica armazón geométrica, en beneficio de lógicas integradoras de las tres ecologías (medioambiental, social y mental).We do not habit cities, but territories, the city-territory that is not a tree but rhizome, a system that produce the multiplicity, a superficial extension bifurcated in all directions (networks) that, in its zones of intensity, generates concretions (nodes, centralities). How can we articulate this city that grows undefined and with no program? Perhaps with an urbanism which aiming not to the representation of the Idea, but to the immanent production of space and sense. Urbanism for the expression of the subjectivity through ecological codes projected on the territories, to ensure the sostenibility of their potentialities. Thereby, that investigation is about a planning whose role is the modelization of the field, to define diagramatic outlines as graphics and procedimental expression for outfit of relational infrastructure to the contemporary city. Diagrams which result of the weakening of their classic geometric structure, for the integration of the environmental, social and mental ecologies

Caracterización de microencapsulados aplicados sobre materiales textiles

La aplicación de microencapsulados a los textiles no es una aplicación que esté tan extendida como en otros campos, como puedan ser las industrias farmacéuticas, agroalimentarias y cosméticas. Los microencapsulados son una nueva forma de obtener acabados textiles que resultan de la aplicaciónsobre los tejidos de estos productos lo que proporciona "acabados no convencionales". La microencapsulación ha permitido la obtención de tejidos con fragancias y perfumes resistentes a los lavados. Los microencapsulados para aplicaciones textiles, a diferencia de las utilizadas en farmacia, no necesitan membranas solubles, salvo excepciones, ya que los principios activos de los núcleos de las microcápsulas, se liberan por rotura de la cápsula, o por permeabilidad de la misma; esto supone una diferencia importante con el resto de fabricaciones de microcápsulas, así como en las características de los polímeros a utilizar para las membranas, lo que nos proporciona un motivo de estudio. El uso continuado, de tejidos con microencapsulados conteniendo una materia activ cuyo efecto se manifiesta por rotura de algunas capsulas, evidentemente, genera una degradación y una pérdida del efecto transmitido y será todavía mayor, si se le suman los efectos de los mantenimientos. En este trabajo se ha determinado la degradación de las microcápsulas (sobre tejidos), en función del uso y el mantenimiento. Para ello se han preparado tejidos con concentraciones variables de un mismo producto (aroma microencapsulado) y sometido a diferentes ensayos. En la aplicación de los microencapsulados sobre los textiles, se han realizado ensayos, exclusivamente por impregnación, puesto que es el procedimiento que mejores resultados nos ha proporcionado. Como trabajo previo se han analizado las características de los productos microencapsulados comerciales, determinando el tamaño medio de las microcápsulas, la cantidad de materia activa por eliminación de agua, su comportamiento térmico mediante calorimetría diMonllor Pérez, P.

BLEACHING NEPTUNE BALLS

Posidonia Oceanic is a seaweed from Mediterranean Sea and it is more concentrated at the Balerian SEA. This implies the Valencian Community also. It forms vaste underwater meadows in the sea and are part of the Mediterranean ecosystem. It is a sea-grass specie with fruits and flowers. Leaves are ribbon-like and they grow in winter and at the end of summer some of them are separated and arrive to some sea line. Fuit is separated and can floate, it is known as “the olive of the sea” mainly in Italy, or as the Neptune Balls. As it can be used in different fields, it is is being studied in order ro have the precitice tests. Some authors have reported the manufacturing of fully bio-based comites with a gluten matrix by hot-press molding. And it has been considered as an effective insulator for building industry or even though to determine the presence of mercure in the Mediterranean sea some years ago. As many applications can be designed from that fibers, it has been considered to be bleached in order to used them in fashionable products. Consequently, its original brown color is not the most suitable one and it should be bleached as many other cellulosic fibers. The aim of this paper is to bleache neptune balls however, the inner fibers were not accessible at all and it implied not to bleach the inner fibers in the neptune ball. Further studiesd will consider bleaching the individualized fibers

A comparison between padding and bath exhaustion to apply microcapsules onto cotton

The final publication is available at Springer via http://dx.doi.org/10.1007/s10570-015-0600-8[EN] The use of Microcapsules has increased in the textile sector. They have been applied as a possible means of introducing new products to textiles, such as insect repellents, antibiotics, skin moisturizers, etc. Microencapsulation technology has improved the fragrance durability on fabrics. Historically, the durability of the fragrance was poor, especially once the fabric had been washed. Microcapsules have been used in textiles for many years, however their previous characterization, adhesion behaviour and permanence on the fabrics are not well known. Nowadays the majority of textile industries are not able to characterize commercial products, or to study the process of adhering the microcapsule to the fibre's surface nor their functionality. Thus, the characterization of microencapsulated fabrics with different active core and the knowledge of the various application processes becomes a major challenge in the field of microcapsules use. There are various industrial processes to apply microcapsules, but determining optimal amounts of products, temperature, conditions and other process variables are an important challenge for the textile sector in order to achieve the highest depositions and retention of microcapsules. This work is focused on determining and quantifying presence fragrance microcapsules when applied onto fabrics by padding and by bath exhaustion and determining which method is the most effective. Consequently, diverse analysis techniques such as microscopy (SEM), spectroscopy FTIR and XPS have been used. We concluded that proposed techniques seem to be useful to compare fabrics treated with microcapsules. Results demonstrate that padding application gives better yields than bath exhaustion.Bonet Aracil, MA.; Monllor Pérez, P.; Capablanca Francés, L.; Gisbert Paya, J.; Díaz-García, P.; Montava Seguí, IJ.

Studying bath exhaustion as a method to apply microcapsules on fabrics

[EN] Textile industry is one of the fields that have increased their consumption of microcapsules. They can be applied to textiles using different methods, such as, padding, bath exhaustion, spraying and foaming. Although the most extended industrial application is by padding, commercial brands also suggest bath exhaustion as a possible procedure. In the research reported herein, bath exhaustion treatments are compared to padding. X-ray photoelectronic spectroscopy (XPS) technique showed that it was a suitable method to detect microcapsules¿presence on fabric surface. Results reported that high concentrations were required to obtain similar behaviours to those of padding. Moreover, we suggested reusing bath exhaustion baths, in order to minimise the loss of so much product in wastewater. We concluded that it was not possible because microcapsules de flate following contact with water for a per- iod of time, and what is more interesting, microcapsule preparation must be done immediately before use, so as to avoid microcapsule de flation due to contact with water.Authors gratefully acknowledge the financial support received by this research project from the Spanish government in the programme "Plan Nacional 2008-2011" reference Mat 2009-14210-C02-01.Bonet Aracil, MA.; Capablanca Francés, L.; Monllor Pérez, P.; Díaz García, P.; Montava Seguí, IJ.

Thermal behaviour of microencapsulated fragances on cotton fabrics

Microencapsulated products are very common in some fields, such as pharmacy, and the textile industry has recently incorporated them into their products. First, this research assessed the presence of fragrance microcapsules on cotton fabric using different padding applications and evaluated them using scanning electron microscopy (SEM) and Fourier transform infrared spectroscopy (FTIR). When the OH stretching region between 3700-3000 cm(-1) from spectra was examined, we proposed some area ratios to quantify the microcapsules' presence on the fabric. The ratios proposed showed that when the concentration of microcapsules in the padding bath increased, their value increased too. Secondly, we analyzed the effect that thermal treatment can cause on microcapsules. This was undertaken using hot air at 120 degrees C, 140 degrees C and 160 degrees C, or by ironing the fabric impregnated with microcapsules at 110 degrees C, 150 degrees C and 200 degrees C, by ironing 1, 5 and 10 times on the analyzed zone. It was found that when the temperature was higher than 120 degrees C, microcapsules were deflated and damaged. This could be seen using SEM images and checked using FTIR analysis.The authors are grateful to COLOR CENTER Company for kindly providing the microencapsulated samples used in this study.

Improvement of microcapsules adhesion to fabrics

[EN] The presence of microcapsules has increased in the textile field. They have been applied as a possible means of introducing new products to textiles, such as fragrances, antibiotics, skin hydrants, etc. This work studied the influence of resin on the adhesion of microcapsules to cotton fabrics. To paste microcapsules to fabrics, they should be in contact with a bath which contains microcapsules, resin and water. Different concentrations of resin were applied to a fragrance microcapsule bath by impregnation. This research focuses on determining the influence of resin quantity on the microcapsule resistance to washing out of the fabrics during washing treatments. Two experimental techniques, scanning electron microscopy and counter apparatus, were used to determinate this influence. We conclude that with a higher quantity of resin, more microcapsules remain on the fabric surface. It was shown that longer microcapsules are washed out of the fabric faster than smaller microcapsules.Financial support from the Valencian Regional Government in the program of IMPIVA for increasing competitiveness in Valencia Companies ref: IMPCNG/2008/5, is gratefully acknowledged.
