  • Introduction

    Welcome Note

    Dear Students,

    Greetings! and a very warm welcome to all of you.

    This is Mst. Murshida Khatun, and I am here to conduct your new course Textile Physics and share and learn something new about the world of Physics. So, let's gather knowledge with you all together. Feel free to approach me any kind of problem.

    Physics plays a large part in textile technology. But, while there are many applications to textile processing, these are diverse and cannot usefully be studied except as part of the technology of the processes themselves; however, the study of the structure and physical properties of fibres, yarns, and fabrics forms the unified subject that is legitimately called textile physics, and which is an essential part of the education of any textile technologist.

    Thank you very much.

    Regards,


    Course Teacher
