"The book has been prepared considering the dire need of the students. It is indeed intriguing to note that no text books are available, that cover the entire sequence of processes in the area of weaving preparation. Students therefore had to refer to a number of books. The unique feature of the book is that it meets the syllabi requirements of the universities/polytechnics.

The book is divided into four division, namely, winding, warping, sizing and drawing. A special chapter has been devoted to the preparatory aspects of micro denier yarns. Also the latest BTRA norms are included. This makes the book very valuable to students. The topic on winding covers all the basic aspects of the winding process, technological developments, winding aspects of sewing threads, and winding of packages for dyeing. The section in warping discusses about the types of warping, productivity, quality related aspects and modern developments. The section on sizing deals with the basic process, principle, chemistry, developments and quality control. The readers will find the book to be very useful for teaching as well as learning."
