1. Morphoagronomic characterization of a germplasm collection of Furcraea spp. and Agave spp.
ABSTRACT This work was carried out in Antioquia, Colombia, in a collection of the Furcraea and Agave genera, important in the country for manufacturing strings, sacks, geotextiles, and handicrafts Currently, to enhance its use, applications have been developed in textiles, biodegradable materials and thermo-acoustic insulation, among others. The aim of this

2. Leachate and vinasse used in a biological process combined with Fenton’s reaction: a green method for treatment of textile effluents
Abstract: The production of textiles generates a large amount of liquid residues considered to be environmentally problematic and which, if discarded without due treatment, may cause eutrophication of water sources, the intoxication of living beings, and the blocking of light penetration. Some methods have been applied for the treatment of this type of waste

3. Bond strength evaluation between textiles reinforced mortar with carbon nanotubes and concrete substrate
Abstract The influence of using carbon nanotubes to improve bond strength between textiles reinforced mortar and concrete was investigated. Forty-two specimens were tested using double-shear test to evaluate the effect of various parameters such as CNTs addition, type of textile material, bond length and width, and number of TRM layers on the bond behavior.

4. APPLICATION OF POLYCARBOXYLIC ACIDS AS BINDERS FOR TiO2 IMMOBILIZATION ON COTTON TEXTILES
ABSTRACT Immobilizing the photocatalyst on a support is an alternative solution to a critical issue in photocatalysis, which is the need for unit operations to remove the photocatalyst from the effluent. In this work, TiO2 was immobilized onto a cotton textile substrate by polycarboxylic acid binders (succinic and citric acids) using a solution deposition me

5. Vestindo o escravismo: o comércio de têxteis e o Contrato de Angola (século XVIII)
RESUMO O comércio transatlântico de escravos africanos esteve estreitamente relacionado às transações de manufaturas entre europeus e africanos, em particular, de tecidos, como, há décadas, a historiografia tem demonstrado. Em Angola, o comércio nos portos e sertões, para obtenção e exportação de cativos, também teve como elemento fundamental a

6. Fabrication of poly(lactic acid) incorporated chitosan nanocomposites for enhanced functional polyester fabric
Abstract This study dealt with the fabrication and analysis of poly(lactic acid) (PLA) mediated chitosan nanocomposite. Such a novel nanobiocomposite may get future applications in drug delivery, and nanofinising of textile and polymer surfaces. Herein, this nanocomposite has been considered as an antibacterial finishing agent for a hydrophobic textile fabr

7. Retardantes de chama bromados: uma revisão
Polybrominated diphenyl ethers (PBDEs), Polybrominated biphenyls (PBBs), Hexabromocyclododecane (HBCD) and Tetrabromobisphenol A (TBBP-A) are flame retardant widely used in plastics, textiles, furniture, consumer electronics, automobiles, among others.They are important components added to retard the spread of flame and, thus,mitigate deaths and destruction

8. Constitutive behaviour of quasi-brittle materials with anisotropic friction
This paper presents an approach to a constitutive model for anisotropic quasi-brittle materials, developed in the framework of rate independent softening plasticity, involving a yield criterion in which an anisotropic friction tensor is involved. It turns out to be useful for materials characterized by ultimate behaviour which varies according to the directi

9. Development and characterization of the amidoxime/Europium (ІІІ)-chelated complex fibers
This paper presents a study of the amidoxime/Europium (ІІІ)-chelated complex (AECC) fibers which can be used as functional fibers for technical textiles such as decorations, protections and medical textiles etc. First, the EuCl3solution were prepared and reacted with amidoxime fibers using optimized process conditions at 50 °C, 5 hours. Subsequently, the

10. Properties and controlled release of chitosan microencapsulated limonene oil
Chitosan microcapsules containing limonene essential oil as active ingredient were prepared by coacervation using three different concentrations of NaOH (0.50, 1.00, 1.45 wt%) and fixed concentrations of chitosan and surfactant of 0.50 wt%. The produced microcapsules were fully characterized in their morphology and chemical composition, and the kinetic relea

12. Acuerdos comerciales y aspectos relacionados con el comercio exterior
La globalización del comercio es una realidad cotidiana por la que se luchó durante décadas por parte de varios países hasta que finalmente se impuso. No obstante, la actual crisis económica mundial, la situación de sectores como la agricultura, los textiles y el vestido, la existencia de cerca de 300 acuerdos comerciales, problemas de seguridad de los países y la lucha contra el terrorismo, entre otras causas, han puesto sobre la palestra la liberalización del comercio y el rol de las aduanas y de las instituciones del derecho aduanero que, de facilitadores del comercio, pasan o pueden pasar a convertirse en verdaderos arsenales de medidas contra el libre comercio, con barreras no siempre conocidas o fácilmente identificables. Así, se hace necesario el estudio de esta problemática, partiendo de lo que se establece desde los entes reguladores del comercio mundial y las aduanas –OMC y OMA− y los acuerdos comerciales hasta el estudio de las barreras que se imponen al tráfico comercial. Y, tratándose de un tema del interés de todos los países, qué mejor que conocerlo o repasarlo de la mano de profesores de varios países, entendiendo que el mismo se basa en buena parte en normas internacionales, algunas de las cuales están armonizadas, lo que hace indispensable conocer las opinión y la experiencias de expertos venidos de diferentes lugares además de la postura de los profesores nacionales. Para esta oportunidad se cuenta con conferencistas de Argentina, Colombia, Ecuador, España, Perú y Venezuela.
