11 Fibres
The textile fibres of commerce are very numerous. They are usually placed in " three natural classes, vegetable, animal and mineral. The rayon filaments so far produced are all vegetable. " Vegetable fibres can be classified as follows: - Seed fibres, growing from the seeds or seed-capsules of certain plants, as cotton, Bombax, Asselepias, etc. Stem fibres, growing in the bast of certain plants, as flax, hemp, jute, etc. Leaf fibres, occurring in the leaves of certain plants, including New Zealand hemp, Manila hemp, etc. Fruit fibres, of which the sole member worth mentioning is the cocoanut fibre. Artificial fibres, represented by viscose, cellulose acetate, cuprammonium and nitrocellulose rayon. The chief fibres in the animal class are wool, silk, and the various kinds of animal hair such as camel, llama, angora, rabbit, horse, etc. The chief member of the mineral group is asbestos, a substance that resists the action of fire. Gold, silver and copper used in the making of tinsel yarns are not fibres as they do not require to be spun. Cellulose-Acetata Rayon - Filaments composed of an acetic ester of cellulose coagulated or solidified from its solution. Cuprammonium Rayon - Filaments composed of regenerated cellulose which has been coagulated or solidified from a solution of cellulose in ammoniacal copper oxide. Nitro-cellulose Rayon (Chardonnet) - Filaments composed of regenerated or denitrated cellulose which has been coagulated or solidified from a solution of nitrated cellulose. Viscose Rayon - Filaments composed of a regenerated cellulose which has been coagulated or solidified from a solution of cellulose xanthate. The preceding four definitions are proposed by the American Society for Testing Materials, Corn. D-13 -
12 Swan, Sir Joseph Wilson
[br]b. 31 October 1828 Sunderland, Englandd. 27 May 1914 Warlingham, Surrey, England[br]English chemist, inventor in Britain of the incandescent electric lamp and of photographic processes.[br]At the age of 14 Swan was apprenticed to a Sunderland firm of druggists, later joining John Mawson who had opened a pharmacy in Newcastle. While in Sunderland Swan attended lectures at the Athenaeum, at one of which W.E. Staite exhibited electric-arc and incandescent lighting. The impression made on Swan prompted him to conduct experiments that led to his demonstration of a practical working lamp in 1879. As early as 1848 he was experimenting with carbon as a lamp filament, and by 1869 he had mounted a strip of carbon in a vessel exhausted of air as completely as was then possible; however, because of residual air, the filament quickly failed.Discouraged by the cost of current from primary batteries and the difficulty of achieving a good vacuum, Swan began to devote much of his attention to photography. With Mawson's support the pharmacy was expanded to include a photographic business. Swan's interest in making permanent photographic records led him to patent the carbon process in 1864 and he discovered how to make a sensitive dry plate in place of the inconvenient wet collodian process hitherto in use. He followed this success with the invention of bromide paper, the subject of a British patent in 1879.Swan resumed his interest in electric lighting. Sprengel's invention of the mercury pump in 1865 provided Swan with the means of obtaining the high vacuum he needed to produce a satisfactory lamp. Swan adopted a technique which was to become an essential feature in vacuum physics: continuing to heat the filament during the exhaustion process allowed the removal of absorbed gases. The inventions of Gramme, Siemens and Brush provided the source of electrical power at reasonable cost needed to make the incandescent lamp of practical service. Swan exhibited his lamp at a meeting in December 1878 of the Newcastle Chemical Society and again the following year before an audience of 700 at the Newcastle Literary and Philosophical Society. Swan's failure to patent his invention immediately was a tactical error as in November 1879 Edison was granted a British patent for his original lamp, which, however, did not go into production. Parchmentized thread was used in Swan's first commercial lamps, a material soon superseded by the regenerated cellulose filament that he developed. The cellulose filament was made by extruding a solution of nitro-cellulose in acetic acid through a die under pressure into a coagulating fluid, and was used until the ultimate obsolescence of the carbon-filament lamp. Regenerated cellulose became the first synthetic fibre, the further development and exploitation of which he left to others, the patent rights for the process being sold to Courtaulds.Swan also devised a modification of Planté's secondary battery in which the active material was compressed into a cellular lead plate. This has remained the central principle of all improvements in secondary cells, greatly increasing the storage capacity for a given weight.[br]Principal Honours and DistinctionsKnighted 1904.
