Patent GB-483571-A (GB)
Title: Improvements relating to the treatment of textile fabrics
IPC: D06M15/423
Filed: 1936-10-21
Abstract: Yarns and fabrics comprising cellulosic fibres are rendered resistant to the tendering action of light by impregnating with an artificial resin precondensate of the phenolic or carbamidic type and insolubilizing the resin so that the final resin content is 3-8 per cent.  Suppleness and crease-resistance are substantially unaffected. Insolubilization of the resin may be effected by heat, by steeping in a cold concentrated solution of a salt such as calcium chloride, or by allowing to stand for several days after drying.  In examples: (1) an aqueous mixture of dicyanodiamide and urea together with some barium hydroxide is heated for 1/4 hr. at 50-60 DEG  C. and carbon dioxide passed in to precipitate barium carbonate; the solution is diluted with water and used for impregnating a cotton-warp fabric which is then dried and heated to 200 DEG  C. for 50 secs., and washed off in weak alkali; (2) a urea-formaldehyde precondensate has an acid or potentially acid substance added, is diluted and used to impregnate a viscose-weft fabric, which is dried, and heated to 200 DEG  C.  In both cases, wet tensile strength after prolonged exposure to light is substantially improved.

Abstract: 291,851. Imray, O. Y., (I. G. Farbenindustrie Akt.-Ges.). March 7, 1927. Anthraquinone - hydroazines. - The 9 : 10- disulphuric acid esters, or their salts, of anthrahydroquinones having an amino group, monosubstitued or not, in #-position and a free aposition ortho to the amino group, are converted into va.t dyes by the action of oxidizing agents at raised temperatures in slightly acid solution. In examples (1) the disodium or dipotassium salt of 2-aminoanthrahydroquinone-9 : 10-disulphuric acid ester is heated with ferric chloride or with a mixture of ferric and ammonium or sodium sulphates; the product dyes cotton fast blue shades from the vat, (2) the disodium salt of 2-amino- 6 (or 7)-methylanthrahydroquinone-9 : 10-disulphuric acid ester is heated with ferric and sodium sulphates to obtain N : N<1>-dihydro-6 : 6<1> (or 7 : 7')- dimethyl-1 : 2 : 2<1>: 1<1>-anthraquinoneazine, which dyes in reddish-blue shades from a blue vat; the N : N'-dihydro-6 : 6<1> (or 7 : 7<1>)-dichlor- and - 6 : 7 : 6<1>: 7<1>-tetrachlor - anthraquinoneazines are similarly obtained from the corresponding mono- and dichlor - aminoanthrahydroquinone-9 : 10-disulphuric acid esters, (3) the disodium salt of 2- methylamino - anthrahydroquinone - 9 : 10 - disulphuric acid ester is converted into N : N'-dimethyl-1 : 2 : 2'- : 1<1>-anthraquinoneazine by heating with ferric sulphate solution, and (4) the disodium salt of 2-amino-7 : 8-benzanthrahydroquinone-8 : 10-disulphuric acid ester is heated with ferric and sodium sulphate; the product dyes cotton from the vat in blue shades becoming green on exposure to the air. 2-Aminoanthrahydroquinone - 9 : 10-disulphuric acid esters.-The above-mentioned disulphuric acid esters are obtained by reducing the corresponding acetylamino compounds and treating the resulting leuco compounds with a halogensulphonic acid in the presence of a tertiary base, the acetyl group being finally eliminated by saponification. The 2-amino- and 2-methylaminoanthrahyroquinone-9 : 10-disulphuric acid esters are thus obtained from 2-acetylamino- and 2- acetylmethylamino - anthraquinone. The 2- amino-6 (or 7)-methylanthrahydroquinone-9: 10- disulphuric acid esters are obtained by condensing 4-nitrophthalic anhydride with toluene, reducing, closing the ring, acetylating and treating the acetyl derivative as set out above. The 2-amino-6 (or 7)-chlor, -6 : 7-dichlor, and -7 : 8- benz derivatives are similarly obtained from 4-nitrophthalic anhydride and chlorbenzene, o-dichlorbenzene, or naphthalene. Specification 278,229, [Class 1 (i), Chemical processes &c.], is referred to.

[Also in Group XL (b)] An electromagnetic wave energy absorbing medium comprises resistive material dispersed in a dielectric and in combination with conductive material in such proportions that substantially equal amounts of electric and magnetic energies are dissipated and the wave impedance of the medium is therefore almost entirely resistive. Resistive particles, e.g. comminuted iron or non-magnetic material, may be dispersed throughout a dielectric to form an isotropic energy-absorbing medium 10 in a co-axial line 11, 12, Fig. 1. The medium 10 may be moulded into blocks or discs or extruded upon a line conductor. The optimum radius of the particles is of the order of one radian length( 1/2# of wavelength) measured in the material of the particle. In a line having spaced conductors 11, 12, Fig. 3, alternate dielectric layers 13, 14 may be used having dispersed resistive and conductive particles respectively. The thickness of the layers should be less than one radian length. The electrical length of an air-filled line may be increased, Fig. 4, by surrounding the conductor 12 with energy-absorbing medium 10<SP>111</SP> of suitable thickness.
