Effect of Incorporating Design Data into New Fabrics

I will try to give you some idea of the complex problems which the practical textile manufacturer faces in connection with the incorporation of design data into the production of parachute fabrics. There are probably no other classes of textile fabrics in large scale production which are covered by such exacting specifications regarding so many properties. Because many of these properties are closely inter-related, the change in the requirements for any one of them is very apt to throw others out of balance and when this is done great problems develop in the textile manufacturing and processing plants. Our good friends, in the Materials Laboratory, have fortunately been keenly aware of these facts and have proceeded very cautiously when they desired to make changes or additions to specifications, and I would like to give them full credit for having done a wonderful job in respect to the development of very effective, very practical specifications, covering a considerable range of parachute fabrics.
