We all have some questions to answer because we are curious and want to make the world a better place to live. I am primarily support engineering research to environment, production managements, or high efficiency with low cost products. We are most interested in research that could affect a large number of people. Once we understand the research gaps in these fields, we assess which gaps are underfunded and seem most amenable to progress if funded. And when the Fabrics are the only engineering products inherent to a person from the moment of his birth until his death, and since clothes cannot be produced without waste, and the amount of these wastes has reached 91 million tons annually, it was necessary to search for a solution to this problem, and this is my goal in this book.
