Corfam poromeric shoe upper material is checked foot by foot for uniformity of texture, color and thickness at the DuPont Company's Old Hickory, Tennessee plant. Corfam is the result of 200 man hours of research and testing at the chemical company.
Continuous roll of Corfam poromeric shoe material is inspected at DuPont's pilot plant for the man made upper material in Newburg, New York. A full scale plant is being built by the chemical company at Old Hickory, Tennessee and commercial quantities will start to come off the line late in 1964. Corfam is the result of 200 man years of research and testing by DuPont.
Final inspection of the cellulose or man made sponge manufactured at the Buffalo plant of E.I. du Pont Nemours & Company showing another diversification of the chemical industry. This sponge has found uses in industry and in the home where the natural sponge failed to produce the service desired. Girls in the picture are preparing the sponges to be wrapped and boxed.
Bobbins of twisted yarn are checked on creel preparatory to winding on beam for weaving. Each individual strand, called an end, must be wound with meticulous care to insure steady feed in high speed weaving operation. Machine at DuPont's $5,000,000 Textile Research Laboratory at Chestnut Run near Wilmington, Delaware is part of production facilities supplementing research in seventeen physical and chemical laboratory units to diversify and improve uses of company's man-made textile fibers.
Every roll of cellophane cellulose film, which is slit to customers' requirements, is weighed and inspected. The illustration shows how the operation is conducted in the plants of E.I. du Pont Nemours & Company.
Intermediate inspection of the substrate for DuPont's Corfam poromeric shoe upper material is one of the many quality control points in the manufacturing process at Old Hickory, Tennessee. At this stage, the substrate is inspected visually for thickness and uniformity. Research and development of Corfam required 200 man years, with much of the effort devoted to perfecting the final product.
