61 Cross, Charles Frederick
[br]b. 11 December 1855 Brentwood, Middlesex, Englandd. 15 April 1935 Hove, England[br]English chemist who contributed to the development of viscose rayon from cellulose.[br]Cross was educated at the universities of London, Zurich and Manchester. It was at Owens College, Manchester, that Cross first met E.J. Bevan and where these two first worked together on the nature of cellulose. After gaining some industrial experience, Cross joined Bevan to set up a partnership in London as analytical and consulting chemists, specializing in the chemistry and technology of cellulose and lignin. They were at the Jodrell laboratory, Kew Gardens, for a time and then set up their own laboratory at Station Avenue, Kew Gardens. In 1888, the first edition of their joint publication A Textbook of Paper-making, appeared. It went into several editions and became the standard reference and textbook on the subject. The long introductory chapter is a discourse on cellulose.In 1892, Cross, Bevan and Clayton Beadle took out their historic patent on the solution and regeneration of cellulose. The modern artificial-fibre industry stems from this patent. They made their discovery at New Court, Carey Street, London: wood-pulp (or another cheap form of cellulose) was dissolved in a mixture of carbon disulphide and aqueous alkali to produce sodium xanthate. After maturing, it was squirted through fine holes into dilute acid, which set the liquid to give spinnable fibres of "viscose". However, it was many years before the process became a commercial operation, partly because the use of a natural raw material such as wood involved variations in chemical content and each batch might react differently. At first it was thought that viscose might be suitable for incandescent lamp filaments, and C.H.Stearn, a collaborator with Cross, continued to investigate this possibility, but the sheen on the fibres suggested that viscose might be made into artificial silk. The original Viscose Spinning Syndicate was formed in 1894 and a place was rented at Erith in Kent. However, it was not until some skeins of artificial silk (a term to which Cross himself objected) were displayed in Paris that textile manufacturers began to take an interest in it. It was then that Courtaulds decided to investigate this new fibre, although it was not until 1904 that they bought the English patents and developed the first artificial silk that was later called "rayon". Cross was also concerned with the development of viscose films and of cellulose acetate, which became a rival to rayon in the form of "Celanese". He retained his interest in the paper industry and in publishing, in 1895 again collaborating with Bevan and publishing a book on Cellulose and other technical articles. He was a cultured man and a good musician. He was elected a Fellow of the Royal Society in 1917.[br]Principal Honours and DistinctionsFRS 1917.Bibliography1888, with E.J.Bevan, A Text-book of Papermaking. 1892, British patent no. 8,700 (cellulose).Further ReadingObituary Notices of the Royal Society, 1935, London.

63 Abel, Sir Frederick August
[br]b. 17 July 1827 Woolwich, London, Englandd. 6 September 1902 Westminster, London, England[br]English chemist, co-inventor of cordite find explosives expert.[br]His family came from Germany and he was the son of a music master. He first became interested in science at the age of 14, when visiting his mineralogist uncle in Hamburg, and studied chemistry at the Royal Polytechnic Institution in London. In 1845 he became one of the twenty-six founding students, under A.W.von Hofmann, of the Royal College of Chemistry. Such was his aptitude for the subject that within two years he became von Hermann's assistant and demonstrator. In 1851 Abel was appointed Lecturer in Chemistry, succeeding Michael Faraday, at the Royal Military Academy, Woolwich, and it was while there that he wrote his Handbook of Chemistry, which was co-authored by his assistant, Charles Bloxam.Abel's four years at the Royal Military Academy served to foster his interest in explosives, but it was during his thirty-four years, beginning in 1854, as Ordnance Chemist at the Royal Arsenal and at Woolwich that he consolidated and developed his reputation as one of the international leaders in his field. In 1860 he was elected a Fellow of the Royal Society, but it was his studies during the 1870s into the chemical changes that occur during explosions, and which were the subject of numerous papers, that formed the backbone of his work. It was he who established the means of storing gun-cotton without the danger of spontaneous explosion, but he also developed devices (the Abel Open Test and Close Test) for measuring the flashpoint of petroleum. He also became interested in metal alloys, carrying out much useful work on their composition. A further avenue of research occurred in 1881 when he was appointed a member of the Royal Commission set up to investigate safety in mines after the explosion that year in the Sealham Colliery. His resultant study on dangerous dusts did much to further understanding on the use of explosives underground and to improve the safety record of the coal-mining industry. The achievement for which he is most remembered, however, came in 1889, when, in conjunction with Sir James Dewar, he invented cordite. This stable explosive, made of wood fibre, nitric acid and glycerine, had the vital advantage of being a "smokeless powder", which meant that, unlike the traditional ammunition propellant, gunpowder ("black powder"), the firer's position was not given away when the weapon was discharged. Although much of the preliminary work had been done by the Frenchman Paul Vieille, it was Abel who perfected it, with the result that cordite quickly became the British Army's standard explosive.Abel married, and was widowed, twice. He had no children, but died heaped in both scientific honours and those from a grateful country.[br]Principal Honours and DistinctionsGrand Commander of the Royal Victorian Order 1901.

64 Artificial Wool
Is really a recovered waste product, and has grown to an important branch of the textile industry. A large quantity of cheap suits are made from these yarns, of which there arc several varieties, known as mungo, shoddy, extract wool, etc. The various wool wastes which are obtained from rags and waste containing wool, cotton or other fibres are so treated that the vegetable fibres are destroyed by chemical means. The animal fibres remaining are respun into yarns. The term is wrongly applied because the fibre is actually wool, although recovered (see also under Mungo, Shoddy, Extract Wool). The term is also given to a rayon fibre manufactured in Italy and sold as "Snia-fil". The Wool Textile Delegation should give a definite ruling on materials such as this which have no wool in their make-up (see Wool Substitutes) -
65 Fibreglas
Fibreglas textile fibres are produced by two methods, the continuous filament process and staple fibre process. In each process glass marbles, made from melted and refined raw materials are remelted in small electrical furnaces, each of which has many small holes in the base of the melting chamber, through which the molten glass flows in fine streams by gravity. In the continuous filament process more than 100 filaments are drawn simultaneously and gathered into a thread or strand. The strand is attached to a high-speed winder that, as it draws the strand, attentuates each stream of molten glass to a fraction of the diameter of the hole through which it emerges. In the staple fibre process the streams of molten glass are struck by jets of high-pressure air or steam which attentuate the glass into fibres varying in length from 8-in. to 15-in. These fibres are driven on to a revolving drum on which they form a web, which is gathered from the drum and wound on to a tube in the form of a sliver. Strands of either continuous filament or staple fibres are twisted and plied into yarns on standard textile machinery. Fibreglas yarns are particularly suitable where fire-proofness, resistance to acids or other chemicals other than alkalis is demanded. Uses include electrical yarns, cords, tapes, cloths and sleevings which form the basis for a plain and varnished or impregnated electrical insulation material; chemical filter fabrics, anode bags used in electroplating, wicking for oil lamps and stoves, pump diaphragms, special fabrics for resisting high-temperature fumes and acids, facing materials for insulating or acoustical blankets, also rubber-coated, acid-proof and waterproof fabrics. Decorative uses include draperies, shower curtains, tablecloths, bedspreads, lamp shades and some apparel accessories, such as men's neckties. Also decorative work in architecture, dress fabrics, particularly for fancy effects, non-stretching cord for use in radio indicating dials, bookbinding, fire-screens, etc. -
66 Fireproof Cloth
Cotton cloth treated with various chemical solutions is rendered flameproof, but only asbestos is truly fireproof. For fabrics that are not to be washed, sodium tungstate, borax, boric acid, aluminium acetate or sodium silicate are used mixed with some organic salt such as gypsum, chalk, Epsom salts, china clay, alum, etc. For fabrics that are to be washed such as flannelette - A soaking in a solution of sodium stannate and then in a solution of ammonium sulphate, dried and washed, will render the material flameproof. This process forms a more or less insoluble compound on the fibre. Other compounds used are aluminium sulphate and after-treatment with desodium hydrogen phosphate, to form aluminium phosphate on the fibre (see Asbestos cloth) -

68 Burring
This is a process in wool yarn manufacturing to extract burrs, seeds, vegetable matter, etc., from the raw wool. These impurities are destroyed without injury to the fibre by the chemical action of dilute sulphuric acid. They are also removed mechanically by the burring machine. The chemical method is preferred for wools containing a large quantity of small impurities, while the burring machine is usually employed for fine wools, as the natural strength and colour of the fibres is preserved. -
69 Nylon
Nylon was first made in the laboratories of E.I. du Pont de Nemours, of Wilmington, Delaware, U.S.A., under the direction of the late Dr. W. H. Carothers as a result of researches started 1928. In October, 1938, it -was announced to the world that a new form of textile fibre had been made by man, and that " nylon " was to be its name. Nylon stockings were on sale to the general public in U.S.A. on May 15, 1940, and many other items of wearing apparel were shown at the New York Pair that summer. In Great Britain, plans made jointly before the war by Courtaulds and Imperial Chemical Industries were responsible for production being started in 1941 by British Nylon Spinners Limited. The " 66 " polymer (each molecule of these reagents contains 6 carbon atoms and hence the name or designation " 66 ") was first made in 1935. Nylon is a name, not for a single material, but for a whole class or family of entirely new materials. There are many nylons and there may be many more. Nylon is the generic or family name for them all, just as glass and coal are names of classes of substances. Nylon, in the general sense, is a man-made material having a chemical composition akin to proteins, of which silk, hair and wool are examples, although nylon has not an exact counterpart in nature. It is not an " artificial " product, nor a man-made copy of a natural material. It can be made up into powders, sheets, solutions, strands or yarns, each with special properties according to requirements. The " 66 " polymer, from which yam is made, was synthesised in 1933, although not announced to the world until October, 1938. The raw material from which the diamine and acid for making " 66 " polymer are obtained are phenol from coal, oxygen and nitrogen from the air, and hydrogen from water. Particularly suitable where high elasticity is required. Uses include parachute fabrics, tyre cords, glider tow ropes, shoe laces webbing, braid, tape and thread, fully-fashioned hosiery, seamless hosiery, underwear fabrics, lace, nets, dress fabrics, marquisettes, neckties, transparent velvet, coated fabrics for raincoats and food covers. Industrial uses include shoe fabrics, sash cords, window screens, filters and bolting fabrics, also slip covers, motor car upholstery, shirtings, tents and shower curtains. -
70 Bevan, Edward John
[br]b. 11 December 1856 Birkenhead, Englandd. 17 October 1921 London, England[br]English co-inventor of the " viscose rayon " process for making artificial silk.[br]Bevan began his working life as a chemist in a soap works at Runcorn, but later studied chemistry at Owens College, Manchester. It was there that he met and formed a friendship with C.F. Cross, with whom he started to work on cellulose. Bevan moved to a paper mill in Scotland but then went south to London, where he and Cross set up a partnership in 1885 as consulting and analytical chemists. Their work was mainly concerned with the industrial utilization of cellulose, and with the problems of the paper and jute industries. Their joint publication, A Text-book of Paper-making, which first appeared in 1888 and went into several editions, became the standard reference and textbook on the subject. The book has a long introductory chapter on cellulose.In 1892 Cross, Bevan and Clayton Beadle discovered viscose, or sodium cellulose xanthate, and took out the patent which was to be the foundation of the "viscose rayon" industry. They had their own laboratory at Station Avenue, Kew Gardens, where they carried out much work that eventually resulted in viscose: cellulose, usually in the form of wood pulp, was treated first with caustic soda and then with carbon disulphide to form the xanthate, which was then dissolved in a solution of dilute caustic soda to produce a viscous liquid. After being aged, the viscose was extruded through fine holes in a spinneret and coagulated in a dilute acid to regenerate the cellulose as spinnable fibres. At first there was no suggestion of spinning it into fibre, but the hope was to use it for filaments in incandescent electric light bulbs. The sheen on the fibres suggested their possible use in textiles and the term "artificial silk" was later introduced. Cross and Bevan also discovered the acetate "Celanese", which was cellulose triacetate dissolved in acetone and spun in air, but both inventions needed much development before they could be produced commercially.In 1892 Bevan turned from cellulose to food and drugs and left the partnership to become Public Analyst to Middlesex County Council, a post he held until his death, although in 1895 he and Cross published their important work Cellulose. He was prominent in the affairs of the Society of Public Analysts and became one of its officials.[br]Bibliography1888, with C.F.Cross, A Text-book of Papermaking.1892, with C.F.Cross and C.Beadle, British patent no. 8,700 (viscose). 1895, with C.F.Cross, Cellulose.Further ReadingObituary, 1921, Journal of the Chemical Society.Obituary, 1921, Journal of the Society of Chemical Industry.Edwin J.Beer, 1962–3, "The birth of viscose rayon", Transactions of the Newcomen Society 35 (an account of the problems of developing viscose rayon; Beer worked under Cross in the Kew laboratories).RLH -
71 Whinfield, John Rex
[br]b. 16 February 1901 Sutton, Surrey, Englandd. 6 July 1955 Dorking, Surrey, England[br]English inventor ofTerylene.[br]Whinfield was educated at Merchant Taylors' School and Caius College, Cambridge, where he studied chemistry. Before embarking on his career as a research chemist, he worked as an un-paid assistant to the chemist C.F. Cross, who had taken part in the discovery of rayon. Whinfield then joined the Calico Printers' Association. There his interest was aroused by the discovery of nylon by W.H. Carothers to seek other polymers which could be produced in fibre form, usable by the textile industries. With his colleague J.T. Dickson, he discovered in 1941 that a polymerized condensate of terephthalic acid and ethylene glycol, polyethylene terephthgal-late, could be drawn into strong fibres. Whinfield and Dickson filed a patent application in the same year, but due to war conditions it was not published until 1946. The Ministry of Supply considered that the new material might have military applications and undertook further research and development. Its industrial and textile possibilities were evaluated by Imperial Chemical Industries (ICI) in 1943 and "Terylene", as it came to be called, was soon recognized as being as important as nylon.In 1946, Dupont acquired rights to work the Calico Printers' Association patent in the USA and began large-scale manufacture in 1954, marketing the product under the name "Dacron". Meanwhile ICI purchased world rights except for the USA and reached the large-scale manufacture stage in 1955. A new branch of the textile industry has grown up from Whinfield's discovery: he lived to see most people in the western world wearing something made of Terylene. It was one of the major inventions of the twentieth century, yet Whinfield, perhaps because he published little, received scant recognition, apart from the CBE in 1954.[br]Principal Honours and DistinctionsCBE 1954.Further ReadingObituary, 1966, The Times (7 July).Obituary, 1967, Chemistry in Britain 3:26.J.Jewkes, D.Sawers and R.Stillerman, 1969, The Sources of Invention, 2nd edn, London: Macmillan.LRD -

76 Cottonin
A substitute for cotton produced in Russia. It is made from Kendir (or Kendyr) fibre which undergoes a special chemical treatment, and it is stated that flax and hemp also can be used. -
77 Dyes
The following list gives a general classification of colouring matters for dyeing textile fibres: - Acid Colours dye animal fibres only and have no affinity for cellulose. If union goods are dyed with acid dyes the cotton remains white and the wool is dyed. They dye wool and silk from baths containing Glauber's salt and some acid, hence their name. Acid colours consist principally of the Azo compounds and are fairly cheap, so are used for the dyeing of dress materials, suitings, etc. No preparation of the fabric is necessary prior to dyeing. Wool and silk fabrics ate simply steeped in a warm acidified solution. Azo Dyes - These are colouring matters used for cotton dyeing and are developed direct on to the fibre. Basic Dyes - Cotton has no direct affinity for basic dyes, which consist of colour bases in combination with other chemicals, as tannic acid, sumach, or other tanning substances. Tannic acid is taken up by cotton which will then absorb the basic colours. They are very bright but not very fast. They dye wool and silk direct from plain baths. Developing Colours - See Developing Colours. Direct Cotton Colours - Dye cotton, linen, wool or silk directly, will dye cotton direct but by the addition of various salts deeper shades are obtained. With the addition of a little acid will dye wool and silk. See direct Dyes. Mordant Colours - As a rule these are very fast to washing and mostly fast to; light, such as logwood, black, Turkey red, etc. The mordant forms insoluble compounds with the colours, which are then applied to the fibres so that the insoluble coloured compounds are formed within the fibres The cotton is prepared first with some metallic mordant, as chrome, iron or alumina. Substantive Dyes - Have the property of dyeing fibres direct. They are Direct Dyes, that is they have an affinity for fibres. Sulphur and vat dyes are substantive towards cotton. Sulphur Colours are used for vegetable fibres only. These colours are insoluble in water and require the addition of sodium sulphide which converts them into soluble substances which will dye cotton. Usually fast to washing and alkalis - not so fast to bleaching (see Sulphur Colours). Vat Colours - These are fast dyes for cotton. They are insoluble in water so are converted into a soluble compound by some chemical reducing agent, and then they have a direct affinity for cotton which is dyed when immersed in the solution. There are two main classes, those prepared from anthraquinone and those related to indigo. They will dye viscose and cuprammonium rayons (see Vat Dyes) -
78 Kendir
The bast fibre obtained from the plant Apocynum Venetum or A. Sibiricum around the Adriatic Sea. It grows wild. It is of recent introduction into commerce and used for ropes, nets, bags, etc. Under suitable chemical treatment it can be spun into yarns of medium counts and used as a substitute for cotton in coarse fabrics. It is also known as Dog's Bane. -
79 Retting
After rippling, the stalks of flax plants are " retted " to destroy resinous matters which bind the fibre to the wood portions. Retting is a system of putrefaction by steeping the plants in water, or by mechanical and chemical means. The principal methods are: - Steeping in stagnant water for up to 15 days. Dew retting by spreading over fields for 30 to 35 days. Steeping in running water. -
80 Skin Wools
These are the product of the fellmongering industry as carried on in the Colonies, on the Continent, and in this country to a smaller extent. They consist of the wool removed from the skins of sheep slaughtered for mutton purposes. Many of these " skin " wools are of excellent quality; but large quantities, through unsatisfactory treatment during separation, and because of the absence of sorting, and neglect in skirting, picking, etc., are only useful for medium and low-class goods. Such wools lack spinning property, have a harsh handle, and do not mill and dye in the manner of the " fleece " wools. " Skin " wools are of the following types: - (1) Sun-dried and removed from the skin by a process of sweating; (2) separated by chemical agency, chiefly by sodium sulphide; (3) sliped from the skin after fibre separation through the application of lime (see slipe). Mazamet, France, is a great centre of the fellmongering industry, and a big business is done. Wools that are often of excellent quality and colour are taken from skins collected from all the principal wool-growing parts, and forwarded to all the important manufacturing centres through agents. Wools of Class 2 are largely the product of Colonial fellmongering stations in which the industry is of more recent growth. The system employed is the sodium sulphide process. Sodium suphide has the property of destroying the epidermis of the skin while improving the quality of the pelt. A 10 per cent solution of sodium sulphide will dissolve wool completely in 15 minutes. After washing, the skins are painted on the flesh side with thick paint of sodium sulphide. The skins are allowed to lie overnight, and the roots of the wool become loosened, the hair bulbs being destroyed, after which the wool is readily pulled by hand.
