Title: Reinforcement of textile materials
IPC: D04H1/74
Filed: 1975-09-15
Abstract: 1527733 Non-woven fabric HOECHST AG 15 Sept 1975 [13 Sept 1974] 37861/75 Headings D1R and D2B A non-woven fabric is bonded with a polymer containing groups of formula In example 4 340g butyl acrylate, 60g acrylonitrile and 20g acrylamide are emulsion polymerised in the presence of 500 ml water, 25g sodium alkylsulphonate and 7.5g ammonium peroxidisulphate. To the polymer dispersion at pH 2.6 is added 20.8g N-methylol-formamide at 60‹C and the temperature maintained at 60‹C for 90 minutes to convert the acrylamide units to units of partial formula I. Alternatively, as in ex. 1-3, a copolymer is obtained from a monomer mixture containing 0.2 to 50% by weight of the monomer where R 1  and R 2  may each be independently hydrogen or methyl. The monomer mixture may also include 40 to 95% of acrylic and/or methacrylic esters having 1 to 8 carbons in the alcohol radical, e.g. butyl and isooctyl, 0.5 to 2% of acrylic and/or methacrylic acid, 0-6% of acrylamide and/or methacrylamide, 0-47% of other monomers having one olefinic double bond, e.g. acrylonitrile, styrene, crotonic or maleic acid or ester thereof, ethylene and propylene and 0-5% of butanediol, dimethacrylate, diallylphthalate, tetraallyloxethane or other polyolefinic monomer. Copolymerisation is carried out at 10 to 90‹C in an aqueous emulsion in the presence of specified peroxy catalysts, reducing agents and emulsifiers. The polymer is stable to storage. It may be cross linked at above 80‹C or above 50‹C in the presence of acid or alkaline catalysts. Polymers containing sufficient (meth)acrylic acid units are soluble in water. Fabric. Fibres or filaments of jute, cotton, linen, viscose or cuprammonium rayon, cellulose 2¢ or 3 acetate, wool, silk, glass, asbestos, polyester, polyamide, polyacrylonitrile, modacrylic, polyolefine, polyvinyl and/ or polyurethane may be formed into carded, wet laid, felted or spun laid fabrics and may be needled or stitch bonded. As 25-55% aqueous solution or emulsion of the copolymer binder is applied by spraying, padding, dipping or doctoring to give an uptake of 10 to 100% of solids based on the weight of the fibres. In Example 5 a carded polyester fleece was coated by spraying 15g/m<SP>2</SP> of copolymer onto each side. In example 6 suction was applied to the reverse side to cause the copolymer to largely penetrate the fleece to form a filter. The bonded or coated fabric may be dried at 60-100‹C on a perforated drum, conveyor or cylinder then heated to 80-250‹C to cross-link the copolymer, or the drying and crosslinking steps may be combined.

Title: Process of treating phosphate rock
IPC: C05B11/06
Filed: 1961-10-26
Abstract: Water insoluble citrate soluble calcium phosphate, which is more basic than dicalcium phosphate is produced by heating a mixture of finely divided phosphate rock and finely divided ammonium sulphate to a temperature of 373-500 DEG  C., hydrating the intermediate product with ammonia while maintaining the temperature below 80 DEG  C. to produce calcium phosphate and ammonium sulphate and separating the ammonium sulphate from the calcium phosphate. Ammonium sulphate solution may be added to the hydrated intermediate product before reacting it with ammonia.  In a preferred aspect the hydrated intermediate product may be reheated to a temperature of from 375 DEG to 500 DEG  C. and again hydrated at a temperature of 100 DEG  to 130 DEG  C. before the addition of the ammonium sulphate solution.  The hydrated product obtained after the reheating is suspended in the ammonium sulphate solution and the suspension may then be added to another ammonium sulphate solution containing the ammonia. Phosphoric acid may be added to the mixture of hydrated product and ammonium sulphate solution in an amount sufficient to react with substantially all the calcium present in excess of that in combination with P2O3 in the phosphate rock to form calcium phosphate.
