3 Fehling's Solution
This consists of two solutions: (1) 34.639 gr. of crystallised copper sulphate dissolved in a litre of water; (2) 173 gr. sodium potassium tartarate dissolved in a litre flask to which is added 57 gr. caustic soda of 1.12 gr. (containing 60 gr. sodium hydroxide) and filling up to the mark.Dictionary of the English textile terms > Fehling's Solution

13 Soyeuse La
One of the early types of rayon, invented in France about 1909 and made from spruce pulp or cotton seed husks. It takes dyes, bleaching and finishing better than cottony and resists boiling in caustic soda solution for several minutes. It is claimed to be not more combustible than cotton. -

15 Viscose
Viscose was discovered by two English chemists, Charles F. Cross and E. J. Be van, working in collaboration at Kew, near London, who found that when cellulose was treated with disulphide of carbon in the presence of caustic soda, it was converted into a golden yellow plastic compound which dissolved readily in water. A solution of the plastic was of such viscosity that it was named " viscose," a name that was destined to become world famous, seeing that round about 88 per cent of the world production of rayon is now made by the viscose process. In 1892 Cross and Bevan were granted a patent on the viscose process and it was applied to many purposes before the production of a textile thread was successfully accomplished. Fundamentally, the manufacture of viscose rayon is fairly simple. The raw material may be wood pulp, pulp from cotton linters, or a mixture of the two. The greater part of the world's viscose is made from wood pulp. Viscose rayon manufacture comprises seven distinct treatments as follows: - 1. Making and purifying the cotton or wood pulp which forms the cellulose base. 2. Caustic soda treatment of the cellulose base thereby forming alkali cellulose. 3. Treatment of alkali cellulose with carbon disulphide, forming cellulose xanthate. 4. Dissolving the cellulose xanthate in weak caustic soda to form cellulose solution or viscose. 5. Spinning viscose into yarn. 6. Bleaching, purification and finishing of the yarn. 7. Preparing the yarn for weaving and knitting. -
16 Seersucker
CRINKLE, or SEERSUCKEROriginally a silk fabric with flat and puckered stripes alternating across the fabric. Now applied to cotton dress fabrics of the better quality crimp styles, woven 32-in. wide in many weights. Two beams are required, one for the crimp stripes and one for the ordinary. One cloth has 72 ends and 72 picks per inch, 2/60's and 30's warps, 32's weft, super Egyptian yarns (see Seersucker) ————————SEERSUCKER (See Crinkle)This term is common in the U.S.A., and given to a plain and crimped stripe fabric either bleached or dyed, and used for drapery and furnishings as well as dress purposes. A common quality is made 40-in. wide 64 ends and 64 picks per inch, 26's warp, 20's weft. Woven from two beams in stripes of plain weave and crimp which is also plain weave. The plain ground ends are firmly weighted and the crimping ends are lightly weighted. Fancy designs are obtained by using colour or rayon in the warps. Another class of seersucker is made from a plain cotton cloth that is printed in stripes with a preparation that will resist the action of caustic soda. The cloth is passed through a concentrated solution of caustic soda and the imprinted part shrinks. The effect is that of crimped stripes.

17 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 -

19 Cotton Flax
A name given to flax fibres that have been steeped in a weak solution of caustic soda, boiled in a vat containing 5 per cent of carbonate of soda, and immersed in a vat of water acidulated with sulphuric acid. -
20 Madder Bleach
The most thorough bleach that cotton cloth receives. The process takes about four days and consists of several long boilings with alkalies and a final treatment with bleaching powder. It gives a full white and is generally used for goods to be printed. The usual procedure is as follows: - (1) Singeing to burn off all loose fibre. (2) Grey soaking, a simple steeping in water. (3) Lime boil, boiling in lime water for about ten hours under pressure, then washed in water. (4) Lime sour, a washing in cold acid solution of about 1 per cent strength. (5) and (6) Lye boilings in dilute solutions of caustic soda with resin soap for about ten hours. The sixth operation omits resin soap. (7) Chemicking, treatment in cold dilute solutions of bleaching powder, afterwards washing in water. (8) White sour, treatment in cold dilute acid solution as in No. 4. (9) Thorough washing in water and then drying.
