JL HE victory convention of the American Association of Textile Chemists and Colorists was held on Jan. 3 to 5, 1946, at the Hotel Pennsylvania in New York City. Presentation of several papers on new developments in the textile field was made to this well-attended gathering of the industry. The meeting closed on Jan. 5 with the award of the Olney Medal of 1945 to Milton Harris, director of research of Milton Harris Associates, at the association's annual banquet in the Grand Ballroom of the hotel. The medal, endowed by the Howes Publishing Co. and named after Louis A. Olney, first recipient of the award, is given each year for outstanding achievement in the field of textile chemistry. A. P. Howes, president of the Howes Publishing Co., made the formal presentation after Alban Eavenson, past president of the AATCC, spoke on "The Medalist—the Man", and H. A. Neville, director of the Institute of Research of Lehigh University, spoke on "The Medal· ist—the Scientist".
A large portion of the papers presented at the meeting concerned the remarkable contributions made by the industry in the recent war. The protection and comfort of the American military man in the varied climates to which he was exposed were accomplished by the development of fabrics and textile finishes which could meet extreme conditions of weather and wear.
In his· paper, "The Quartermaster Fights the Weather", W. M. Lee of the office of the Quartermaster General pointed out that in addition to the usual conditions of temperature, humidity,
matical, physical, biological, medical, and social sciences) ? and the extension of investigative findings and theories of a scientific or technical nature into practical application, including the experimental production and testing of models and processas.
(b) "Federally financed research and development" means research and development financed in whole or in part from funds designated for research and development by the Federal Government under a contract, grant, or other form of financial assistance.
(c) "Government agency" includes departments, independent agencies and commissions, corporations, and other instrumentalities of the Federal Government.
(d) "Organizations" includes state and local government agencies, corporations, partnerships, nonprofit institutions, ana individuals.
(e) "Scholarships and fellowships" means stipends covering tuition and other fees/ and such living, travel, and other expenses as the Administrator may determine.
light, wind, rain, snow, and ice the effect of alkaline dusts, salt spray, blown sand, and mildew had to be considered when designing the fabrics for the tentage and clothing of the armed forces. In the case of tentage the problem of flammabiiity had to be solved. The successful solution of this latter problem is shown by the fact that no deaths or injuries caused by burning tents were reported.
Extensive work was done in the field of water-repellent clothing. Prospe. t ive fabrics were subjected to a series of laboratory tests which included wet abrasion, field laundering, dynamic equilibrium, and air permeability. Confirmation of these tests was then made on a rain course which had been installed at Camp Lee. Soldiers wearing clothing made from these materials performed a basic set of maneuvers in a continuous artificial rainstorm coming from a series of 50-foot standpipes. The violence of the storm could be changed from a heavy downpour to a penetrating drizzle. In this way, the actual wear conditions under which the fabrics would be used were simulated.
R. A. Pingree of the Warwick Chemical Co. discussed German work in the field of water-repellents. Their efforts were directed mainly toward decreasing the water-absorptive characteristics of rayon to the point of equaling cotton and wool. In addition to work on aluminum salt-wax emulsions with which we are familiar they used zirconium salts in emulsion with high molecular waxes of a type not available in this country. It is possible that this latter treatment may exhibit some advantage in durability over our corresponding treatments. Probably their most important development in durable type water
repellents, according to Mr. Pingree, vras their work using an aqueous dispersion of octadecyl ethylene urea. This material supplied i n the form of an emulsion is d i luted with water at room temperature to a concentration o f approximately 5%. T h o material i s passed through this emulsion, squeezed, and dried in a normal manner at any temperature above 80°. N o additional heat treatment is necessary since reaction takes place with the fiber during the drying operation. I t is also unnecessary to subject the material to any neutralizing or washing treatment since the product is practically neutral and the drying operation produces no by-products.
The aromatic ethylene ureas were also studied and one type of these compounds shows promise of development in the water-repellent field for use on wool and possibly on nylon and other synthetic fibers. Various resin-forming materials were used to increase the water resistance of rayon and it w a s found that the shrinkage and creasing resistance was increased as well. A condensate of melamine formaldehyde and triethanolamine used in solution with zinc nitrate or glycollic acid as a catalyst seemed to» increase solubility with less embrittling o f the fiber.
Considerable interest was shown in the paper by M. A. Dahlen on "Dyestuff Developments in Germany during World War II". Although 5 5 % of all the I . G. Farbeh properties are located in the Russian zone of occupation most of the dyestuff plants are in the American and British zones. Mr. Dahlen reported that in general the I. G. technical personnel responded very well to our requests and data on 119 dyestuffs and pigments were obtained. In the main these materials were merely extensions of classes of dyes alreadjr known and no new chromophores or startling products in a cnemical sense were to b e reported. Mention was made, however, of a new method of screen printing in which a. light-activated polymerization catalyst i s used in conjunction with a water-soluble resin on a fine metal screen. Exposure to a n are light using the patter on translucent material much in the manner of a photographic negative results in polymerization of the resin where exposed. After this, the unpolymerized resin is removed by washing.
Wm. D . Appel, president of the AATCC, announced plans for an expanded program of the association. These included the appointment recently of H. Stiegier as the first full-time director of the association's varied and dispersed research activities. H e will be charged with the coordination of the efforts of the many subcommittees and the associates at Brown University, National Bureau of Standards, tfcte university of Chattanooga^, and the association's own laboratories at Lowell Textile Institute. The latter lal£ oratories are to be strengthened and additional siibcoammittees will be formed to handle many new projects.
