Teaching and e-Learning about Cotton Ring Spinning Frame

Summary/Abstract: This paper presents a modern, e-learning method designed for the study of the ring spinning frame for processing cotton fibers, blends of cotton and chemical fibers or chemical fibers cotton types. It envisages a new teaching and learning approach for the laboratory of subject Processes and Machines in Cotton Spinning Mill comprised in the academic curricula of the 3rd year students, specialization Technology and Design Textile Products, by combination of text based learning with audio-visual support. The ring spinning frame is placed at the end of the technological flowchart for processing of cotton and cotton blends for manufacturing of classic yarns. Within this machine the roving resulted from the roving frame is transformed into yarn. The main operations carried out in the spinning process comprise: drawing of roving, twisting of the fibrous and winding of yarn on the cops. The work is done in Power Point aiming to capture the attention of the students. Besides, the transition from chapter to chapter or to additional relevant aspects within a chapter is accomplished by means of hyperlinks. The kinematic and technological schemes developed on AutoCAD serve to calculus (kinematic and technological) and facilitate a better understanding of the machine functioning, part of the machine or different mechanisms. Supplementary, several images, audio and video files support the learning and understanding process. The video material derives from personal records or from processing films available in the public space, www.youtube.com, using Adobe Premiere Pro CS6 software. For each kinematic or technological parameter to be calculated, the respective kinematic chains are revealed by changing the properties of the respective entities (kind, thickness or color of gears). The paper can be accessed from the official website of the university, http://www.uav.ro/, in the platform https://core.uav.ro/ containing all the bibliographic materials uploaded for students. The access requires a username and password, both for teachers who publish information and for students as users.
