- PublicaciónAcceso abiertoEstudio de vigilancia tecnológica para la exploración del uso de fibras PET en la industria textil(Universidad de Ibagué, 2022) Tique Muñoz, María Fernanda; Salazar Camacho, Natalia Andrea; Sánchez Echeverri, Luz AdrianaDado el gran impacto ambiental generado por la industria textil, se han propuesto diferentes estrategias tanto a nivel comercial como gubernamental para mitigar dicho problema. Dentro de estas propuestas, el reciclaje se encuentra como pilar fundamental y la transformación de botellas PET en fibras textiles es actualmente una de las alternativas más llamativas en el mercado; sin embargo, uno de los principales inconvenientes es la afectación de algunas de sus propiedades. Partiendo de este punto, el presente trabajo de grado tiene como principal objetivo explorar el uso de fibras PET en la industria textil mediante un estudio de vigilancia tecnológica en donde inicialmente se describe la obtención de fibras PET, luego se describen y caracterizan tratamientos para mejorar sus propiedades y por último se identifican aplicaciones potenciales. Los resultados de este proyecto sirven al mercado y grupos de interés, como base para la toma de decisiones relacionadas con el uso de fibras PET en la industria textil.
- PublicaciónAcceso abiertoInclusiones de tereftalato de polietileno como refuerzo en estructuras de suelo(Universidad de Ibagué, 2019) Rivera Lozano, Andrés Fabián; Bedoya Correcha, Juan David; Salazar Susunaga, María Paula; Rojas Rodríguez, Isabel CristinaThis project aims to evaluate assess the degree of a low-plasticity silt soil using circular inclusions of polyethylene terephthalate (PET) fibers in order to improve the mechanical properties of the soil under analysis. In this way, through time in the civil engineering, its advances in the improvement of the soil have helped to make the structures more stable from their foundations, in the same way in the construction of roads and in the stabilization of slopes. For this reason, in this project it was decided to use polyethylene terephthalate fibers with a geometric shape in circles, with a diameter of 6 mm, handling percentages of PET in the ground of 0.3%, 0.5%, 0.8%, 1% and 1.2%. Having said the above and understanding that this material constitutes a large part of the waste produced daily because it is a material that can be found in many commonly used products, it has led to work worldwide to improve environmental conditions, for Therefore, the use of plastic waste to reinforce the soil and improve its mechanical and physical properties contributes to the environment and to the research of new materials for soil improvement. This project consists of three phases: a first phase deals with the characterization of the soil, where the respective laboratory tests were carried out and the characterization of the Polyethylene Terephthalate was continued, a second phase where the samples were already made of the material with PET inclusions.
- PublicaciónAcceso abiertoRefuerzo de estructuras terreas utilizando tereftalato de polietileno (PET)(Universidad de Ibagué, 2019) Arbeláez Varón, Juan Sebastián; Góngora Plazas, Daniel Fernando; Salazar Susunaga, María PaulaIn this project will be demonstrated the process to improve a clay soil (CH), using an experimental method that consists in including the random ones of PET to improve the mechanical behavior of the soil studied. The way to implement this material will be in the form of strips of PET recyclable material, cut to 8 cm in length, 2 mm in width and 0.5 mm in thickness. This type of plastic material is used. This material is one with a higher demand in consumption market today (angel, 1993). In order to corroborate if there is an increase in the resistance in the soil to be analyzed (CH), a sample of altered soil was taken from the Altamira farm, 3 km from the city of Ibagué. Soil samples including PET fibers will be published using 0%, 0.3%, 0.8%, 1%, 1.2% of the weight of the soil test pieces, 45 test pieces of 4 "dimensions will be prepared. high and 2 "in diameter, discretized in 15 compacted to 15 strokes, 15 with 25 strokes and 15 compacted in 56 strokes Concorde with this, 3 specimens with each percentage of inclusion of PET. As a result of this monograph, the reinforcing material in the PET fibers is obtained, improving the cutting resistance by increasing 137.24% with respect to the specimens without reinforcement.
