Save the Surface and You Save AH! ill I oil ill etC!a its a good adhesive," said the bookbinders, "and we earn break our worst bottleneck,'* Du Pont chemists obliged with mew hot-melt adhesives ............................... By PEG MINER ' ^ ...................... When the art of bookbinding fell into step with ma chine methods, a new idea was bom. About SO years ago, companies in that industry started wondering; "Do we really have to sew or staple the pages together to make books? Why not glue them together using assembly-line techniques?** . The available glues, however, were bad actors. In the bindery, they were temperamental to handle. It took hours for them to dry, and millions of books were standing around in American binderies every day. That meant extra space, extra handling, and a costly delay in the flow of operations. In service, they picked up moisture from the air, weakened, and books started to fall apart. Or in dry climates, they dried out, got brittle, and failed just as badly. Then in 1944 the W.-F. Hall Printing Company of Chicago wrote to the president of Du Pont, saying in effect: "With your research facilities and back ground in bookbinding and adhesives, we think you can help in with our problem. Can you develop an ad hesive that will dry quickly, so we can trim our books right after binding? It's got to be strong and flexible --and stay that way under al climatic conditions." Here was a chance for the Fabrics and Finishes Department to make an original contribution to book binding. So its technical men set to work. After an intensive research program and construc tion of a special pilot plant, they presented Hall and other firms, both large and small, with a completely new type of product--hot-melt adhesives based on a new synthetic resin. Here were materials that were melted at high temperatures, applied to the backbone of a book, and would set immediately on cooling. Books could be trimmed'right away, and the flexible bond was unaf fected by humid weather. It looked like the old bottle neck could be broken. Cooperating with the T. W. and C. B. Sheridan Company of New York, Du Pont engineers than worked on the problems of adapting machines to the new adhesives. To help iron out difficulties, Du Pont even built a complete bookbinding machine--a smaller replica of the giant units used in industry--in a labo ratory of the Finishes Division at Partin, N. J. The lessons learned from this engineering and chemical research made it possible for the binderies to swing into high gear. The first widespread use of the new products was in the familiar "Pocket Books." More than a quarter of a billion of these economical little volumes are now in circulation. Says the director of manufacturing of Pocket Books, Inc.: "The use of Du Pont hot-melts has resulted in books that are more attractive to our readers, since they open flatter. We're very happy the adhesives don't change with changes in climate--and have the permanence and flexibility that were lacking in previous ones." : Next came certain types of catalogs, magazines, such as -Fortum, and larger paper-covered books such as the $1.00 edition of the best-seller, The Cardinal Even some makers of hard-back or "edition" books began to replace their time-honored stitching process with hot-melt adhesives. The trend In that direction seems to be growing--and may someday be industry-wide. I.iwge aheeta of-paper are printed? folded Into so-called........... =......

And "Zelan" keeps its protection even after several washings or cleanings. Later, rainwear was made of cloth coated with linseed oil to make it waterproof. These were the familiar oilskins, or slickers, as they are still known and made today. Although they gave protection from the rain, they were often hot and uncomfortable to wear. Today, rainwear is made from fabrics that are not coated, but are treated with chemicals called water repellents. Such compounds make possible a wide variety of stylish raincoats that are both protective and comfortable to wear. You can also select the degree of protection against rain . . . according to the weave of fabric and construction of the garment. Water repellents are divided into two classes. One type loses its protection after a single trip to the laundry or dry cleaner. In contrast, there are chemicals like Du Pont "Zelan" durable wa ter repellent which keep their protection even after several washings or cleanings. Compounds like "Zelan" impregnate only the individual fibers and do not coat the surface of the fabric. Thus, air can circulate through the small spaces between the fibers. Because of pro tection and comfort, not only raincoats, but jackets and many other types of garments are made from cloth treated with water repellents.
