    • A molten fibre-forming aromatic polyester, obtained by heating a glycol with terephthalic acid or an ester-forming derivative thereof, is extruded or otherwise formed into a ribbon which is rapidly cooled and solidified and then cut into small pieces, chips, or flakes, suitable for feeding into a melt-spinning apparatus for the production of artificial filaments. The glycol used in making the polymer has the formula HO(CH2)nOH, where n is an integer greater than 1 but not exceeding 10. Instead of terephthalic acid there may be used an aliphatic, cycloaliphatic, or aryl ester, or an acid halide, ammonium, or amine salt of terephthalic acid. Rapid cooling of the ribbon may be effected by quenching with water or an aqueous liquid or by using a blast of cold or cooled air or other gas, or by directing the molten ribbon on to an intensely cooled surface such as a rotating and internally cooled metal cylinder or wheel or a moving metal band. In an example, polyethylene terephthalate is prepared in an autoclave provided with a valve and orifice from which the molten polymer is extruded as a thin ribbon. The ribbon impinges on a brass wheel and is quenched by jets of cold water. It is dried in warm air and then fed to a cutting machine. In another example, the molten polymer is forced between rotating nip-wheels set 1/16 inch apart and cooled internally. The ribbon thus formed is passed to a cutting machine. Specification 533,306 is referred to.

    • A finely-divided, inert, inorganic or organic substance or mixture of substances is incorporated with highly polymeric linear esters obtainable by heating glycols of the series HO(CH2)nOH, where n is greater than 1 and not greater than 10, with terephthalic acid or an ester-forming derivative of the acid by adding the substance or mixture of substances in the form of a dispersion in a glycol of the series HO(CH2)nOH, where n is an integer greater than 1 but not exceeding 10, preferably the glycol used in the polyester formation, to the mixture of polyester-forming reactants or to a low molecular weight product thereof and continuing the reaction to yield a highly polymerized product. The substances added may be titanium dioxide, zinc sulphide, barium titanate, barium sulphate, calcium sulphate extended with titanium dioxide, zinc titanate, magnesium titanate, calcium titanate, lithopone, zirconium dioxide, calcium sulphate, aluminium oxide, thorium oxide, talc, mica, kaolin, carbon black, phthalocyanine pigments, lead chromates, iron oxides, chromium oxides and ultramarine, and the particle size is not larger than 25 microns and preferably less than 5 microns. The substances are added in the form of a suspension formed by ball milling the inert filler in the glycol. Ten parts titanium dioxide are ball milled for three days with 115 parts of ethylene glycol, thus obtaining a dispersion of particle size 0.3-1.3 microns. The dispersion is mixed with dimethyl terephthalate, ethylene glycol and magnesium oxide in a closed flask heated to 197 DEG C. while circulating nitrogen therethrough and taking of methanol. The temperature is increased to 277 DEG C. under pressure of 0.3 mm. glycol, being distilled off and a melt obtained which can be extruded into fibres.

    • Cellulosic materials are treated with a halogeno-methyl ether of the general formula R--O--CH2--Hal, in which R is a normal or branched chain aliphatic hydrocarbon radical, saturated or unsaturated, of not less than 8 carbon atoms, and Hal is a halogen atom, the treatment being carried out at a raised temperature in an inert organic diluent or solvent for the reagents, and preferably in the presence of an acid-binding agent. As an alternative, there may be used a quaternary ammonium salt formed from the halogeno methyl ether and a tertiary organic amine. The cellulosic material may consist wholly or in part of natural or regenerated cellulose or cellulose esters, e.g. cotton, viscose or other artificial silk including cellulose acetate material, linen, jute or mixtures of these fibres. Paper or films, threads, yarns, woven or knitted fabrics may be treated. The materials may be dyed. The chlormethyl ethers used are obtained by treating the respective alcohol with formaldehyde and hydrogen halide. Chloro methyl dodecyl, sec-dodecyl, cetyl, or octodecyl ether, or a chloromethyl ether of the mixture of alcohols from sperm oil may be used. The treatment renders the material waterproof and gives it a soft handle and these effects are resistant to laundering and dry cleaning. Toluene, benzene, acetone, carbon tetrachloride, trichlorethylene, and other hydrocarbons or chlorinated hydrocarbons may be used as organic diluent or solvent. Pyridine, aniline, N-alkylaniline or dialkyl aniline, di- or triethylamine, piperidine, alkyl piperidines, sodium or potassium carbonate, potassium acetate, or calcium hydroxide may be used as acid binding agent. The treatment is carried out at raised temperature, preferably at or near the boiling point of the diluent. In an example, a -chloromethyl octadecyl ether is dissolved in dry toluene and pyridine is added. Undyed boiled out cotton limbric is immersed in this solution which is heated at 90 DEG C. The fabric is removed, pressed, washed with alcohol, and dried. In other examples, cotton-wool union fabric, gaberdine and limbric are treated. Cotton fabric is impregnated with a solution of octadecoxymethyl pyridinium chloride in trichloroethylene, squeezed, and dried in a current of warm air. It is then baked at 105 DEG C. Limbric is padded with chloromethyl octadecyl ether, diethylaniline, and benzene mixture. It is dried in warm air and then heated at 120 DEG C. on a drying cylinder. Knitted cellulose acetate fabric is immersed in a solution of toluene containing a chloromethyl ether of sperm-oil alcohols, and pyridine. The solution is heated for 30 minutes and the fabric is then rinsed in alcohol and dried. Specifications 340,555, 390,553, 396,992, and 426,482 are referred to.

    • Blends of aromatic polyesters of the kind obtainable by heating glycols of the series HO-(CH2)n-OH, where n is an integer greater than 1 but not exceeding 10, with terephthalic acid, with other synthetic linear condensate polymers are obtained by heating them together at a temperature above their melting points at least until a homogeneous blend is obtained. The synthetic linear condensation polymers may be polyamides and interpolyamides such as polyhexamethylene adipamide, polyhexamethylene sebacamide, the polyamides from caprolactam, interpolyamides from caprolactam and hexamethylene diammonium adipate, interpolyamides from hexamethylene diammonium adipate, hexamethylene diammonium sebacate and caprolactam; polyesters and interpolyesters such as polytrimethylene terephthalate, polydiethylene glycol terephthalate, polyethylene-1 : 2-ethane bis - (phenoxy - p - carboxylate), polyethylene adipate, polyethylene sebacate and polyethylene hexahydroterephthalate, polyurethanes and polyureas. The heated melt may be stirred, the heating may be effected under reduced pressures, a stream of oxygen-free gas, e.g. nitrogen, may be passed through the melt, or the blending may be preceded by a drying operation. In the examples, blends are made from polyethylene terephthalate and (1) polyhexamethylene adipamide; (2) the interpolyamide formed from hexamethylene diammonium adipate, hexamethylene diammonium sebacate and caprolactam; (3) polyethylene adipate; (4) the polyurethane obtainable from tetramethylene glycol and hexamethylene diisocyanate; (5) polyethylene-1 : 2-ethane bis-(phenoxy-p-carboxylate); and (6) polyethylene hexahydroterephthalate.
