Fiber Science - I is a free Android application developed by Engineering Hub, designed to provide a simple yet detailed guide for textile engineering students. The app offers a clean and organized set of notes that cover all the essential topics of fiber science, chapter-wise.

The first chapter of the app discusses the general classification of fibers, including the structure, properties, and uses of cotton, bast fibers, wool, and silk fibers. The second chapter covers the basic concepts of polymer, its classification, methods of polymerization, molecular weight measurement, and distribution. The third chapter explains the manufacturing process of rayon, nylon, polyester, acrylic, and poly-olefins, along with their physical and chemical properties.

The fourth chapter discusses the advantages and disadvantages of man-made fibers, methods of rectification of man-made fibers, basic requirements for fiber formation, and the concept of order and morphology. The fifth and final chapter covers the physical structure of principal natural and man-made fibers, investigating fiber structures through X-ray diffraction, optical and electron microscopy, and I R absorption.

Overall, Fiber Science - I is an informative and useful app for textile engineering students seeking to gain a comprehensive understanding of fiber science. The app's well-organized content and easy-to-use interface make it a must-have tool for students in this field.
