Implementación de un sistema de lavado de lana en el laboratorio de fibras y lana de la facultad de ciencias pecuarias

Abstract

The implementation of a wool washing system was done in the wool and fiber laboratory, samples of ovine wool were utilized as experimental units to validate the equipment which in tum were compared to fiber of alpaca. The results indicate that in effectuating the design and implementation of the wool washing system, materials of high resistance to corrosion and oxidation were used because they are water-working equipment. The highest results, especially of elongation and hygroscopy percentage (32, 67%), are achieved by washing the ovine wool whilst the best resistance to tension (76, 67 N/cm^2), wool fineness (4, 67 points), coloration (4, 67 points), and tact (4, 50 points), when washing the fiber of alpaca. The quality control, through physical and sensory tests in the laboratory, showed that there is a high efficiency of the equipment that reaches 67%, which will be increased as experience is gained in its operation; however, it is observed very clean, resistant and silky wool. The costs of the mechanical prototype were US $ 2140.15, which are considerably low in relation to equipment of intemational origin that fulfills the same function; nonetheless, its useful life is often inferior to the present mechanical prototype since it has been made with first class materials and skilled labor. It 1S advisable to read the instructions of the maintenance and operation manual for favorable results
