    Welcome Note

    Welcome to my course blog at DIU Blended Learning Center (BLC). This is Alamgir Hossain, and I am your facilitator in this course. I am hopeful that you will find various information and help to complete this course successfully. Yarn Manufacturing I is the first course where you will learn how yarns are produced from fibers and the different steps of yarn manufacturing techniques. The course is designed based on practical knowledge of spinning mills where yarns are manufactured. So this course will be very helpful to build your career in the spinning sector as well as in textile sector.
